Releases / Changelog:

  • v1.2 (20120403):
    • Updated CyanogenMod source.
    • New kernel (based on latest CodeAurora froyo_almond branch).
    • Enable workaround to reduce audio distortion at higher volume levels.
    • Completely fixed instability/freezes related to USB tethering.
    • Various patches for memory leaks and minor bugs from gerrit.
  • v1.1 (20120317):
    • Hotfix 1: disable CGROUPS, fix wireless suspend stability issue
    • 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: reverted to stable 2.6.32.9 kernel due to issues with battery consumption. Note: CGROUPS is still enabled, but the Application Not Responding issue on first boot seems to be fixed
    • Kernel: disabled OTG support due to battery consumption issues (will package a separate kernel for interested testers)
    • Kernel: updated pmem driver, fixed issues with smartassV2 & interactiveX CPU governors
    • Wifi: stability patch for bcm4329 driver
    • wpa_supplicant_6: wait for control interface monitor to be brought up before starting. Improves reliability of wireless when reconnecting from idle.

  • v1.0 (20120227):
    • Known issue: you may see the message "process system is not responding" after unlock on first boot. This is due to CGROUPS being enabled in the kernel (and also happens with the stock kernel - it's not a problem with my updates). You can safely disregard the message as no harm will be done.
    • Hotfix 1test1 [8th March]: Changes to kernel to fix battery drain - please test.
    • Updated CyanogenMod source.
    • Kernel: now using version 2.6.32.57 (Code Aurora's froyo_almond updates + upstream's longterm 2.6.32.y updates merged)
    • Kernel: new bcm4329 wifi driver, which should fix reconnect from idle for hidden networks
    • Kernel config: enabled CGROUPS, tweaks to improve battery usage
    • Scrolling cache tweak.
  • v0.9 (20120203):
    • Hotfix 4test5 [21 Feb]: Revert longterm patches due to random reboot issue.

    • Hotfix 4test3 [20 Feb]: Kernel: rebased to CodeAurora froyo_almond branch & merged longterm 2.6.32.57 changes, updated wifi source driver.
    • Hotfix 3 [12 Feb]: Kernel: more stable config (enabled ARMv6 K extensions which stops USB errors; fix for U8180 key issues).
    • Hotfix 2 [10 Feb]: Fix call audio via Bluetooth headset; disabled AHB overclocking due to instability during USB tethering (and possibly also during other activities); wifi module now built from source to improve reliability; updated wpa_supplicant_6 to use combo scanning; re-enabled SCHED_HRTICK in config (it wasn't the cause of instability).
    • Hotfix 1: Fix audio routing issues that were causing problems with the mic and headset detection during calls. This may or may not affect the Bluetooth headset bug - please let me know.
    • Updated CyanogenMod source (almost 7.2.0-RC1).
    • Performance: disable scrolling cache (prevents lag)
    • Performance/battery: disable ICS rotation animation (it's slow and causes instability; ICS transition animations are still working smoothly)

    • Fancy: enable electron beam animation for screen off by default (performance is satisfactory)
    • Reverted SIM lock change that was causing people to have problems with certain SIM cards.
    • FM: fixed audio routing (headphones will not longer malfunction if you use the speaker and then exit the FM app); prevent frequencies out of bounds being used; allow looping between the top/bottom of the frequency bands.
    • Improved mac address generator script to prevent errors for certain devices.
    • Increased default compcache memory allocation to 26%.
    • Miscellaneous code cleanups.
    • Now distributed via ROM Manager with a greatly simplified installation procedure.
  • v0.8 - 26 January 2012:
    • Updated CyanogenMod source (still 7.2.0-RC0).
    • Fix for rare issue where notification area items can get "stuck", causing notifications to malfunction.

    • Kernel stability fix (disabled SCHED_HRTICK due to instability/random reboot issue).
    • MAC addresses for Bluetooth and wifi are now accurate.
    • Improved Bluetooth audio.conf based on this bug report. This should improve Bluetooth stability with audio peripherals.
    • Reduced default compcache memory usage from 18% -> 10% to reduce potential lag.
    • Reduce LatinIME landscape keyboard key height (.25in -> .23in)
    • Use automatic brightness setting by default.
  • v0.6 - 29 December 2011:
    • Hotfix 2 [31 December 2011]: Updated "madconfig" script. You can now run adb shell madconfig u8180 to activate U8180 ROM branding that will survive future ROM upgrades (of my own release).
    • Hotfix 1 [31 December 2011]: Updated kernel (further stability fixes, added interactiveX cpu scheduler, unlocked overclock frequencies up to 768Mhz); updated libaudio to increase buffer size (this improves smoothness of apps using audio - e.g., Gensoid can now play games at full 50/60fps in landscape with no visual stuttering @633Mhz, whereas before it would stutter constantly); renamed tethering device from usb -> rndis (cosmetic fix); tweaked LatinIME keyboard to use .23in key height (down from .26in).

    • Patched framework to swap volume controls when the phone is rotated 90 degrees.
    • Improve USB transfer speed while in UMS (USB Mass Storage) mode.
    • Fix some graphical corruption on widgets in stock Camera app.
    • Other small fixes.
  • v0.3 - 10 October 2011:
    • Updated CyanogenMod source - final 7.1 release.
    • Improved 2D rendering speed.
    • Switched to EU GPS servers.
    • Fixed headset/media control keys.
    • Re-enabled automatic brightness.
  • v0.2 - 3 October 2011:
    • Hotfix 3 [6 October 2011]: Kernel: reverted to stable compcache (ramzswap) driver. Framework: disabled JNI debugging -this fixes force-close errors in some applications such as TapFish, and increases overall system performance.
    • Hotfix 2 [4 October 2011]: Kernel: improved multitouch driver to fix touchscreen accuracy (especially soft keys), improved haptic feedback, fix to zram module. Small fixes to libaudio (the distortion is not yet resolved, however).
    • Hotfix 1 [3 October 2011]: Kernel: added compcache (zram.ko) module, reduced boot delay, unlocked 729Mhz frequency, small bugfixes. Framework: enable compcache by default (18% RAM usage, customizable in CyanogenMod Settings - Performance -> Compcache RAM Usage.)
    • Updated CyanogenMod source: now based on Gingerbread version 2.3.7.
    • Kernel now supports under/overclock from 30Mhz - 710Mhz (min/max frequency is set to 30Mhz - 600Mhz by default, so you must manually activate the higher frequencies via Settings -> CyanogenMod Settings -> Performance -> CPU settings). Thanks to estebanSannin. NOTE: My phone is very unstable at 691Mhz, and freezes immediately at 710Mhz. I am providing these higher frequencies just in case your phone has better tolerance for overclocking. I accept no responsibility for any damage caused as a result of overclocking.
    • FM Radio app: fixed seeking (left/right arrows).
    • Disabled automatic brightness (it potentially avoids battery drain, and never worked anyway). Thanks to tas0s for the tip.
    • Enable workaround to prevent corruption issues if you use the Simple2EXT app2sd app.
    • Reverted Gallery app to 2D version, due to lack of hardware 3D acceleration on our phone.
    • Added compatibility with sebastian404's ClockworkMod port. You can now install this ROM using his CWM recovery (as well as my own).
    • Improved FM volume calculation, reduced overall volume & small fixes to audio code.
    • Various small bugfixes.
  • v0.1 - 12 September 2011:
    • Hotfix 1 [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; Framework: enabled hardware-accelerated 2D rendering.
    • First release. All hardware appears to be working correctly.
