CyanogenMod 7.2.0+ Galaxy5 Port

News: The galaxy5 device is now officially supported within the CyanogenMod project - I am the device maintainer. This means that in future, you may see future release or weekly builds for the 7.x branch on the CyanogenMod website.

Even though I am an official CyanogenMod developer, you should not consider the builds that I release here as official. I have applied several patches to fix minor issues that are not yet part of the official CyanogenMod code (such as FM radio popping, camera crash on zoom, etc.).

CyanogenMod 7.2.0 Galaxy 5 Port
Latest testing release: none
Latest release: v3.0 [20131216]
Latest Google Apps package: 20110828

Hey folks,

This is a port of CyanogenMod 7.2.0-RC2+, a community-developed Android ROM based on Gingerbread 2.3.7, for the Samsung Galaxy 5 I5500 (Europa) phone. The current port status is stable - most hardware is working correctly, but see post #2 for known issues.

Special thanks to Motafoca for starting CyanogenMod development, OuNao for the fake dual-touch module, sensor work and general assistance, DSM for (re)writing the EuropaParts settings app, DrMacinyasha for the hosting, mikereidis (author of Spirit FM Radio app) for helping with FM audio issues, and of course, thanks to all of you for testing!

Latest Changelog:

• 20131216 [v3.0]
  • md5: 02e59caf63d9ed2c6cac996fefe9b003
    
  • Updated CyanogenMod source
  • Optimization: modify dalvik.vm.dexopt-flags for best performance
  • Optimization: disable .asrc resource compression (improves performance & lowers overall memory usage)
  • Optimization: process png assets using pngquant

• 20130613 [v2.9]
  • md5: 545aa2a59aa3e4b87523b0a96dc909d6
    
  • Updated CyanogenMod source; backported some core libraries to newer Jellybean revisions; libfreetype updated to 2.4.12 with new Adobe CFF rendering engine enabled.
    
  • Kernel: rebuilt with gcc 4.6; fixed Bluetooth wakelock; set default USB configuration when ADB is disabled to pure UMS mode (should be helpful if you need to use mass storage on a user-restricted or old Windows PC); switched from older fsr drivers (built from partial source) to official gingerbread versions (hex-edited for compatibility with our Froyo bootloader). These changes should improve overall phone stability, reliability and performance.
  • Potential fix for battery drain in Phone app that may occur after making/receiving a call (caused by missing proximity sensor).
    
  • Refreshed all proprietary files & wifi driver (same versions used for androidarmv6 cm10.1 build).

  • Small change to fake dual-touch driver to slightly improve touchscreen edge sensitivity.
  • Added support for ROM downloads/OTA updates via MAD Manager. Note: GooManager is still supported - it's your choice which application to use.
    

• 20120401 [v2.3]
  • Hotfix 3 [18th April]: kernel: fix shutdown issue.
    
  • Hotfix 2 [16th April]: kernel: enabled CGROUPS + CFQ IO scheduler (seems to reduce lag), various patches to improve performance/stability; g5sensord updated to v3.4 (low pass filter to reduce compass needle dancing).
    
  • Hotfix 1 [10th April]: kernel: fix headset detection problems, experimental change to improve stability when rebooting to recovery; g5sensord updated to version 3.3 (corrected bug in calibration file, hack to stabilize compass on high pitch)
    
  • Updated CyanogenMod source - version 7.2.0 RC1.
  • New kernel (label: gio2europa). Based on Samsung Gio Froyo source, updated to latest Code Aurora froyo_almond revision. This kernel has a more accurate battery driver, more efficient power saving for the mmc (wifi/sd) interface, and includes many fixes from Samsung and Code Aurora Forum in contrast our original kernel source.
    
  • New wifi driver + firmware (3.0.70.23, from Samsung Gio Froyo system image). This wifi driver is more recent than our official source, has better mmc power management code, and appears to be more stable. The minimum CPU frequency also set to 122Mhz (really). This frequency usually caused sleep of death issues, but this new driver may be immune.
  • Various patches for memory leaks and minor bugs from gerrit.
  • Updated sensor daemon (g5sensord) to latest revision (v3.1) - adds calibration data persistence, calibrated data and magnetic z-axis, saving of hard and soft iron calibration data. Should fix the Google Sky sensor issue. Thanks OuNao!
  • Enable setup_fs tool by default. This tool will check /data and /cache on each boot, ensuring that they are formatted properly as ext4 filesystems. If not, the partitions will be formatted automatically. This should make upgrading from Froyo more painless, and also fixes a common issue in which /cache corrupts randomly (perhaps due to unclean dismounts when the phone is not rebooted properly).
  • GooManager support now working correctly, which allows for future OTA updates.

• 20120317 [v2.2]
  • Hotfix 1: changed kernel config (to test for battery improvements), re-enabled WOW suspend in wifi driver
    
  • Updated CyanogenMod source - version 7.2.0 RC1.
  • Cherry-picked various patches from gerrit to fix issues with core binaries/libraries (dalvik, bionic, zlib, etc.).
  • Kernel: updated europa-battery, pmem, fsa9280, android staging drivers.
  • Kernel: reduce minimum CPU scaling frequency to 122Mhz (to see if sleep of death occurs with the new wireless driver).
  • Wifi: using AR6kSDK.3.0_RC.298 source with patches to allow usage of Samsung's firmware blobs, disable WoW (Wake on Wlan), and fix a certain case in which the driver blocks suspend. Note: the newest driver from freescale (AR6kSDK.3.1_RC.563) is not stable with our phone. This can't be fixed easily, as the problem appears to be within the new proprietary firmware blobs, which is something I can't fix. In the meantime, this driver should work well (and hopefully without any sleep of death issue).
  • dhcpcd: patches to optimize dhcp requests for Atheros AR6003. This improves connection/reconnection speed and reliability.
  • libhardware_legacy: increase wifi loader timeout from 1 second to 5 seconds. This ensures that the wireless driver is given time to settle before the first scan occurs.
  • wpa_supplicant_6: wait for control interface monitor to be brought up before starting. Improves reliability of wireless when reconnecting from idle.
  • libaudio: fix for minimum in-call volume being incorrectly muted in certain cases (including on speakerphone); fix FM audio when using no-microphone headphones.
  • Switched to OuNao's open libsensors - completely fixes accelerometer lag.
  • Switched to "g5sensord", Ounao's open memsicd replacement based on freescale's eCompass code - more battery efficient than proprietary memsicd daemon.
  • GPS: use worldwide SUPL server by default. Initial reports indicate that people are having better connectivity with this setup overall.
  • Compcache: back to 18%.
  • ADWLauncher: lock action buttons by default (helps avoid cases in which users accidentally detach the icons for these buttons).
  • Change scrolling cache setting to further improve scrolling speed.
  • Disable automatic brightness setting by default. Our phone has no light sensor, and I suspect that the software implementation may be causing battery drain.

• 20120305 [v2.1]
  • Hotfix 2test3 [10th March]: Kernel: reverted all changes since v2.0 release (to hopefully prevent battery drain); ar6000: avoid setting refClock rate (may improve wireless stability); reverted to CyanogenMod wpa_supplicant v6.
    
  • Hotfix 2test2 [8th March]: Same as hotfix2test1, but using stable kernel instead. Please compare against hotfix2test1.
    
  • Hotfix 2test1 [7th March]: Reintroduce CodeAurora kernel with fixes for battery usage (but further testing is needed by the community); updated new ar6000 driver to match suspend/resume/bluetooth coexistence behaviour of stock driver; switched to wpa_supplicant & hostapd 0.8.x from Atheros SDK to improve wireless behaviour; fix FM audio when using no-microphone headphones.
    
  • Hotfix 1 [6th March]: New wireless driver (AR6kSDK.build_3.1_RC.563) from Freescale i.MX53 source release - wireless is now stable. Modified source is available on github (freescale branch).
    
  • Updated CyanogenMod source
  • New ar6000 driver (adapted from AR6kSDK3.1 source package used by the Sony PRS-T1/JP e-book reader); enabled combo scanning in wpa_supplicant_6.
  • libaudio: fixed combo device issue (ringtone in speaker + headset/headphone)
  • libsensors: using OuNao's libsensors with change to further reduce battery consumption during idle. This completely fixes sensor lag. Thanks to OuNao.
  • Adjusted smartassV2 CPU scheduler to idle at lower frequencies
  • Enabled CGROUPS in kernel to minimize data starvation issues.
  • Updated fake-dualtouch module to v9.1 (fixed).
  • Enabled Goo-inside.me OTA update support (requires Goo-inside.me app)
    

• 20120206 [v2.0]
  • hotfix 2 (6th February): more fixes for microphone and headset routing. I can't reproduce call echo, so it may or may not be fixed.
    
  • hotfix 1 (6th February): due to popular demand, the microphone has been enabled to allow voice calls. [sarcasm]In future releases this will be a paid feature.[/sarcasm]
    
  • Updated CyanogenMod source (almost 7.2.0-RC1).
  • Kernel: updated OuNao's dualtouch module to the latest version (v9.1, which also has edge sensitivity fix).
  • Kernel: updated android staging kernel drivers from 2.6.35 kernel (notably bringing improvements to the lowmemorykiller driver).
  • Kernel: audio driver patches to prevent rare blackscreen during incoming calls from idle/low memory conditions.
  • Framework: disable scrolling cache (prevents lag in certain apps).
  • Framework: switched to stable copybit version with blending bug fix.
  • Audio: further updates to latest CAF libaudio version with FM support added. Bluetooth calling needs testing (I don't have a peripheral to test).
  • Camera: fixed force close error during zoom.
  • Mobiledata: added 2g/3g mobiledata switch option (you can set the mobiledata button to switch between 2g/3g mode instead of simply turning on/off data)
  • FM: Fix audio routing (where headphones sometimes stopped working after closing the radio app); respect upper and lower frequency limits; looping between low/high frequency limit during manual seek is now possible.
  • Network: SIM lock messages will no longer be ignored. This may help people who have problems using SIM cards that require a PIN unlock (note: this is not related to the reboot problems with certain SIM cards).
  • Updated USBController.cpp (tethering) code to possibly prevent reboots after extended use.
  • Refreshed ClockworkMod Recovery official build to 5.0.2.8 (thanks to koush)
  • Moved to new hosting on goo-inside.me (thanks to DrMacinyasha), which allows for better ROM Manager integration. This also means no more weekend download restrictions!
  • Improved LatinIME key sensitivity (key presses are recognised with better precision than before).
  • Settings -> About phone -> Mod version will now show the exact build date, which helps you to know exactly what version you're running.
  • Update notifications & automatic ROM updating now available (ROM Manager Premium users only).
  • Increased compcache to 26% (may be useful for those who have no swap).
  • Decreased wifi scan interval to 45 seconds to help with reconnection problems if you use hidden SSIDs.
  • Switched to US GPS servers by default.

  • Due to reported problems, reverted to stock wifi driver - the only change is that wireless-N mode is activated.
  • Replaced CyanogenMod's v5 wpa_supplicant with Samsung's v6 version. This should improve wireless signal with the stock driver.
  • Fixed light toggle button in notification menu.
  • Optimizations: reduced VM heap size to 24m, disabled surface dithering.
  • Small tweaks & fixes.

• v1.5 - 1 October 2011:
  • Battery stats wipe?: You must wipe your battery stats in ClockworkMod for this release, since we are using a modified kernel battery driver (and your existing stats file may be invalid).
    
  • Data wipe?: A regular data-wipe is only necessary if you have problems (as usual).
    
  • Hotfix 2 [5 October 2011]: Kernel: Bluetooth initialization fix; enabled compatibility with new basebands - you are now free to use any Froyo-based baseband with CyanogenMod. Framework: enhanced dual-touch compatibility (enabling/disabling dual-touch will now change the touchscreen permissions to the proper type).

  • Now includes fake dualtouch driver by default - see OuNao's Fake DualTouch thread for more details.
    
  • Now using improved ar6000 wireless-N wifi driver (based on Linux compat-wireless-20110329 ath6kl driver, with Samsung's patches for the G5).
  • Small tweaks to the new battery driver's voltages.
  • S2E corruption issues should now be completely solved. If your existing /sd-ext partition is corrupt from previous usage in older ROMs, see post #2 for instructions on how to manually format your partition (this is the only way to clear the bug).
  • [I5508] Touchscreen driver for I5508 now partially working. The x/y axis orientation is correct, but the accuracy is not good. I will try to fix this in future releases/hotfixes.

• v1.4 - 23 September 2011:
  • Battery stats wipe?: You must wipe your battery stats in ClockworkMod for this release, since we are using a new kernel battery driver.
    
  • Data wipe?: A regular data-wipe is only necessary if you have problems (as usual).
    
  • Hotfix 1 [24 September 2011]: Fixed wifi tethering (reverted to v5 supplicant - should not reduce wireless quality as we are still using the newer WEXT driver); fixed stock FM radio; improved FM radio volume code (thanks to OuNao); improved FM audio quality (reduced hiss sound).
    
  • Updated CyanogenMod source.
  • Deodexed ROM: you can now install the full Google Apps package if you desire. Keep in mind that your first boot after upgrade/fresh install will be slower compared to previous versions, but regular boots will continue to be fast.
  • Patch to prevent S2E from applying bad filesystem tweaks (won't interfere if you don't use S2E).
  • Linked /cache/download -> /data/download by default (so all users can download large apps from Market, even if not using an app2sd method).
  • Kernel: Updated battery driver (based on tass_battery.c 2.6.35 kernel driver) - this should reduce battery drain and prevent the phone from staying stuck on 99% battery for extended periods. Note: your battery stats will be erratic for one or two charging cycles - make sure to wipe your battery stats to help this process.
    
  • Wireless: new driver with Wireless-N capability & better signal (based on Atheros source from Samsung I5508, with patches from 2.6.35 kernel).
  • Updated to wpa_supplicant v6 (awext -> wext driver) & reverted to CM7 dhcpcd. This restores wireless signals to Froyo levels.
  • Kernel: Updated fsa9280 USB switch driver (from 2.6.35 source).
  • Kernel: change default TCP congestion control method to "veno" - should improve wireless reliability, especially if there is wireless congestion in your area. It can also improve wireless throughput under normal wireless conditions.
  • Enabled hardware-accelerated 2D rendering (note: this feature wasn't working properly in the previous test hotfixes - it's working now, and there is no graphical corruption).
  • Various small bugfixes.

• v1.3 - 10 September 2011:
  • Data wipe?: only if you have problems.
    
  • Updated CyanogenMod source.
  • Hotfix 2 [18 September 2011]: Boot: removed custom lowmemorykiller tweaks; kernel: various updates (smartassV2, TinyRCU, Simple and V(R) IO schedulers), bugfixes and optimizations, changed default scheduler to Simple IO; libaudio: code cleanup and reduced overall FM volume; Framework: enabled hardware-accelerated 2D rendering.
    
  • Hotfix 1 [10 September 2011]: Fixed volume controls on stock FM app (thanks again to OuNao and Mike).
    
  • Stock FM Radio app now working! Huge thanks to mikereidis and OuNao for the assistance. Note: the volume will be stuck at 100% in the stock app, so take care not to blow out your speakers (will be addressed in a later hotfix). Alternatively, you can use Mike's excellent Spirit FM application which has working volume controls (as well as many other features not present in CyanogenMod's stock FM app). See this thread and Mike's thread on XDA. Be sure to show your appreciation for Mike's work by purchasing the unlock key for his app.
    
  • Boot: small fix to /dev/log/* permissions (was causing log errors).
  • Graphical tweak to improve GUI performance.

• v1.2 - 21 August 2011:
  • Important: mad2sd has been removed from this ROM. Please turn off mad2sd before upgrading, and read the notes in post #2.
    
  • Data wipe?: only if you have problems / forgot to disable mad2sd properly before upgrading.
    
  • Hotfix 2 [7 September 2011]: Kernel: experimental config changes for better battery savings. Framework: fixed lag on incoming call; small fix to "mad2sd" script (note: it is only used to control swap).
    
  • Hotfix 1 [27 August 2011]: Modified kernel config to reduce SD lag; reduced VM heap size to 32Mb; potential fix for lag on incoming call; modifications to better support S2E - its script will now mount the drive with its own parameters, giving better performance. Important: Due to changes in the way S2E works, you must move all folders back to internal memory (and make sure to do a full reboot), before installing hotfix1. When you flash hotfix 1, you should also format /sd-ext, or else you will have problems. See: this post.
    
  • Updated CyanogenMod source.
  • Changed default configuration: 48Mb VM heap size, 18% compcache memory usage.
  • Fixed tethering via 3g.
  • Boot: removed mad2sd, updated CyanogenMod's existing script to properly mount /sd-ext drive as ext4 format.
  • Kernel: small fixes, now built using gcc version 4.4.3 (to increase compatibility with existing proprietary kernel modules).
  • Kernel: rebuilt wifi module using original, unmodified source.

• v1.1 - 13 August 2011:
  • Known issue (not directly related to this release): If you cannot access Google Apps after flashing, you are using a buggy version of ClockworkMod v0.4. Please re-download CWM v0.4 from the latest link in the other topic, reflash CWM, reboot into the fixed CWM, and then flash Google Apps once again.
    
  • Known issue: If you experience the sleep of death issue, make sure you upgrade to hotfix 1.
    
  • Data wipe?: recommended if you have problems.
    
  • Hotfix 2 [14 August 2011]: More fixes to FM routing code (thanks to OuNao); fixed compass direction issues (x2); upgraded brcm_patchram_plus tool; changed hciattach service parameters. Bluetooth initialization should no longer fail, and Bluetooth SCO operation may be fixed/improved - please test.
    
  • Hotfix 1 [13 August 2011]: Increased minimum scaling frequency to 245Mhz. This is necessary to fix sleep of death on some (but not all) phones. If you know that 122Mhz is stable for your device, you can manually set the lower frequency.
    
  • Framework: updated CyanogenMod code (more Gingerbread 2.3.5 code merges).
  • Framework: increased default camera exposure level.
  • Framework: more updates to libaudio FM routing (still needs more work).
  • Kernel: fixed compass direction issues.

• v1.0 - 2 August 2011:
  • Known issue: wifi sleep of death bug is present. Fixed in hotfix1+.
    
  • Hotfix 1: Boot: reduced default minimum frequency to 122Mhz. Kernel: improvements to CPU schedulers, KGSL driver, disabled CGROUPS (it causes slowdown), improved wifi kernel driver. Framework: changed camcorder recording format (playback now works), fixed wifi sleep of death issue.
    
  • Data wipe?: recommended if you have problems (since it is a new Gingerbread point release).
    
  • Framework: updated to Gingerbread 2.3.5 code release.
  • Framework: improved camera quality - should now match or exceed Froyo's camera/video quality.
  • Framework: small fixes to libaudio, and beginning of work to support FM radio (not ready yet).
  • Boot: increased disk readahead cache; various bugfixes & improvements to mad2sd script & init.rc script - reduces startup delay and fixes bootloop problems for some users with slow SD cards.
  • Kernel: reduced sensor wakeups by 50% (less wakeups = less battery used); fixed disk-related stability & SD card lag problems; now using zram.ko module (newer compcache version); improved wifi reliability; improved overclock stability (kernel will now initialize at safe 604Mhz frequency); increased default minimum frequency to 245Mhz to avoid lag when resuming from idle; small improvements to smartass scheduler; re-enabled CGROUPS support; enabled CGROUPS support in BFQ scheduler.
  • Summary: new Gingerbread release, more stable kernel, faster SD card speed, better camera quality, improved battery life.

• v0.9 - 15 July 2011:
  • Data wipe?: not needed.
    
  • Known issue: it's very fast...
    
  • Known issue (really): cannot hang up calls. Fixed with hotfix 1.
    
  • Hotfix6 [20 July]: Framework: reverted to wpa_supplicant v5 with patch for reconnect issue. Wifi is now 100% stable, including reconnect from idle .
    
  • Hotfix5 [20 July]: Boot: increased mad2sd reliability. Framework: now using patched wpa_supplicant_6. This appears to almost completely fix wifi reconnection, but the reconnection may not happen unless you open the Settings -> Wifi menu for some reason. I'll continue troubleshooting, but in the meantime this is a big improvement.
    
  • Hotfix4 [19 July]: Boot: fixed problem with mad2sd script (some people could not activate); fixed incorrect ramzswap module loading. Kernel: really add smartass 122Mhz sound fix (please re-test again). Wifi: backported some patches from 2.6.35 kernel to increase stability of ar6000 module. Framework: replaced Samsung wpa_supplicant with CyanogenMod version (it was causing Google account sign-in problems, and it's just Samsung's dhcpcd that's required to improve wifi stability).
    
  • Hotfix3 [19 July]: Boot: improved init/mad2sd scripts to prevent bootloop problem for some users; ensure /system is mounted read-only. Framework: replaced wpa_supplicant & dhcpcd binaries with Samsung versions - fixes all problems with slow/unreliable wifi (re)connection.
    
  • Hotfix2b [19 July]: Framework: increased Dalvik VM heapsize to 24mb (can improve game performance and fix rare force-close problems with Market and other apps). Kernel: smartass scheduler tweak to fix TuneIn Radio distortion during sleep (please set your minimum CPU frequency back to 122Mhz & re-test); moved some kernel modules from ramdisk to /system (reclaims 5mb RAM); disabled loading of RFS modules (reclaims 5mb RAM); fixed lowmemorykiller properties to avoid unnecessary task killing; re-added compcache module. Please make sure you have version "2b", as the original hotfix2 was buggy.
    
  • Hotfix1 [16 July]: fixes call hangup bug. We were missing some Samsung RIL files.
    
  • Kernel: backported 2.6.35 KGSL & DRM drivers.
  • WiFi: now using ar6000.ko built from source; should solve sleep of death, but connecting/reconnecting is still not 100% perfect.
  • Framework: fixed incorrect cellular network signal reporting.
  • Framework: replaced all adreno200 libs with Samsung Ace Gingerbread versions.
  • Framework: removed all graphics workarounds.
  • Updated CyanogenMod source.
  • Summary: this release has significantly better graphics performance and more stable wifi.

• v0.8 - 10 July 2011:
  • Data wipe?: not needed.
    
  • Known issue: high battery drain and wifi sleep of death issues reported. Please install hotfix2+ to resolve.
    
  • Hotfix4b [13 July]: Kernel update: added CPU & AHB overclocking support. Maximum selectable frequency is now 768Mhz but I do not recommend using the highest value. WARNING: I am not liable for any damage that you may experience as a result of using the overclock feature.
  • Hotfix3 [11 July]: Kernel updates: added interactive, smartass CPU governors (smartass set as new default); added BFQ IO scheduler (set as new default), added ramzswap (compcache) module, CPU frequency selection fix (CPU frequency settings now selectable in Options -> CyanogenMod -> Performance -> CPU); reduced minimum CPU scaling frequency  to 122Mhz. Framework: added compcache support; enabled compcache by default & using 18% of total memory. Translation: big kernel update that should improve responsiveness & increase battery life.
    
  • Hotfix2 [11 July]: reverts kernel + ar6000 to known stable versions. Should fix wifi sleep of death issue.
    
  • Hotfix1 [10 July]: upgrades ar6000.ko module, fixes kernel battery driver - should fix wifi sleep hang and battery drain (battery was not actually draining - the driver was misreporting).
    
  • New kernel based on Samsung Ace/Mini 2.2.1 source release with better kernel config. This fixes all reboot hangs, and should also fix wifi sleep issues, give better stability & performance, and may help reduce battery drain (needs testing).
  • Upgraded all proprietary kernel modules (e.g. AR6000 wifi, NAND fsr & fsr_stl)  to latest versions.
  • Small USB tethering fix - it will refuse to allow tethering if you have UMS enabled.
  • Improved Bluetooth boot-time initialization (should help prevent cases where Bluetooth refuses to turn on).
  • Updated CyanogenMod source & other small fixes.

• v0.7 - 2 July 2011:
  • Data wipe?: yes, you absolutely must data-wipe if upgrading from v0.6 or earlier.
    
  • Hotfix5 [5 July]: Kernel update: ported 2.6.35 USB switch code, disabled control groups, second fix for I5508 MSM legacy touchscreen support. Framework: fixed UsbController.cpp code. This release should really fix I5508 support (but I need testers to confirm), and also fixes USB tethering for all.
    
  • Hotfix4 [4 July]: Kernel update: adds support for Europa I5508, adds CIFS kernel module (if people need to use Samba/sharing apps).
    
  • Hotfix3 [4 July]: fixes audio/call instability & framework restarts related to Bluetooth & the FM radio.
    
  • Hotfix2 [3 July]: fixes sensors, codecs (Youtube now works).
    
  • Hotfix1 [2 July]: fixes WiFi sleep issue.
    
  • Now packaged for ClockworkMod.
  • Updated CyanogenMod source.
  • Fixed camcorder.
  • Reverted to older Samsung kernel (until new kernel is stable enough for use).
