CyanogenMod 9 (Ice Cream Sandwich) based port for HTC Liberty ("Aria/Gratia")

This is a port of CM9 (Ice Cream Sandwich) started by me for Liberty
Currently in Beta

Big thanks to:
CyanogenMod Team
Ganster41 (hardware video decoding)
gladiac(aka modpunk on xda) & Droste from marvel (EGL & HW acceleration, camera, GPS, kernel, and probably more)
munjeni (GPS, EGL & HW acceleration)
s0be (EGL & HW acceleration, kernel)
Qualcomm (ARMv6 ICS GPU drivers needed for EGL & HW acceleration)
Everyone who has shared their working ICS source


  • Pretty much everything not listed below

Partially working:
  • Backlight for navigation buttons (on static brightness) - Turns off with the screen, and only comes back on when the brightness is changed
  • Camcorder - Effects don't work, time lapse doesn't work, only one resolution @ 15fps
    Default camera app will output bad video. Use another app for camcoder until this is fixed
  • Panorama - Slow, preview freezes after capturing (switching to camera/camcorder then back will unfreeze it)

Not working:
  • Voice search and voice button on keyboard
    Solution: delete /system/app/VoiceSearch.apk & download Voice Search from the Play Store

Known bugs (that aren't listed above):

USB Mass Storage pops up in front of everything when USB is plugged in, and after "Preparing SD card" is done (while plugged in)

Sound behavior with headphones/headset plugged in:
Not sure if ICS is like this by design or not, but ringtones notifications and alarms are played through both the headset/headphones and the back speaker.
Media (like music or videos) is only played through the headset/headphones

Mobile data notification tray toggle: Sticks on enabled, but it still toggles the data correctly
Not sure if this is a problem with the button on CM's end, or if it's Liberty-specific.
Hitting another button will fix it

Inserting an SD card while running will sometimes show as damaged. A reboot will fix it

Watching videos for too long can crash the whole system

Emergency calling is untested



MediaFire mirror (slower, ads, captcha):

If Wifi isn't working, try this:

Google Apps for Ice Cream Sandwich:

ROM source:

Kernel source:

Old releases:

Install Guide:
Recovery version 5.* would probably be best

Old bootloader from 2.1 Eclair:
- Update to 2.2 Froyo and S-OFF -

Clean install (from CM7, sense, or any other ROM):
- wipe data/factory reset
- Install ROM package
- Install Google Apps package (optional)

Update from previous CM9 build:
- Install ROM package
- Reinstall Google Apps package (if previously installed)

Normal cache isn't used for anything that persists through reboots (from what I can tell), and the Dalvik cache is updated as needed upon booting (that's what the "Android is upgrading..." message is doing)
The ROM package is supposed to restore Google Apps, but doesn't sometimes, so I added that as a step

Tips & tricks:

FM Radio: Use Spirit FM (and allow any root requests)

Trackball wake:
Open Terminal Emulator and type:
then reboot.
To disable it, run the same thing again.

- Kernel changes (credit to gladiac):
