[DEV] [WIP] [Commtiva Z71/FIH-F0X variant] Ice Cream Sandwich AOSP/CM9
Hi there,
I'm starting new topic to start this ICS porting development for FIH-F0X variant.
calling all F0X developers to start develop this device
this thread talk about build from CM9 source but I've AOSP project before that I use it to port the touchscreen driver
this is history of the release
*for demonstration only*
AOSP build
05022012 then flash this kernel fix
> working touchscreen driver and softkey
02022012
> partially working touchscreen driver, softkey not working*for demonstration only*
#PLEASE DON'T MIRROR THESE FILES#
not working:
- RIL
- graphic
- sdcard
- call/sms
- bluetooth
- wifi
- mic
- video
- audio
- headset
- gps
- auto rotation sensor
- proximity sensor
- etc
and i think almost all features not working so don't give me a protest about it,
and I'll begin the CM9 build from here, maybe cyanogenmod team not support this phone to cm9 as lack of hardware. so
so if you have idea to this device please post in here
problem:
> system partition was too small ~160MB
thanks to:
- tj_style for guidance, touchscreen porting tutorial
- Edgar86 for lastest kernel source
- PJ for device config
- and all people that support this

没看错的话，大意就是这个开发者对z71的4.0做了一些尝试，解决了某些问题。他在大神辈出的XDA号召更多的开发者加入到Z71的4.0的编译中来。
看文章好像现阶段他这个初步的4.0触摸是正常的，但不知是不是像之前那个4.0那样。
自然，依然在初步阶段，not working 一大堆额。想用可用的4.0依然遥遥无期。
所以如果长时间没有换机计划的吧友依然可以期待。


慢慢等吧~

等吧，估计出来也就是刷着玩，然后还得用2.2或者2.3
