Fixed color temperature bug (please see #2).
Port from ZTE V987. Thanks to bruno for the base. Also thank to cloudROM and MIUI teams, their roms helped me for the final fixes. Unfortunately, it is still based on S139 kernel. I couldn't find a way to overcome the issue with messed up touchscreen and orientation. It was working on my phone only.
Don't forget this is just a test version for those who like to experiment. It would be a big luck if everything works as intended, so if you're looking for a bug-free and stable rom, then it's adviseable not to install this version before bugs are fixed.
Install through CWM/TWRP.
Needless to say – make a backup of your current system first.
Spent a lot of nights working on this and finally managed to fix everything…or almost.
Most of the things seem to work, but needs testing. It is guaranteed that won't mess up the touchscreen (verified on another A820).
The ROM is permanently rooted and multilanguage, gapps not included, but you can install from this link: http://goo.im/devs/UniqueDroid/gapps/gapps-4.2.1/gapps-jb-4.2.1-20121129-signed.zip through CWM/TWRP.
If you get installation aborted, then you don't have a proper recovery installed. Download this one http://d-h.st/QxB rename it to recovery.img, copy to sdcard and install through MobileUncleTools (you can download it from Google Play).
Working: GPS, Wi-Fi, Sensors, GSM module, camera, audio, video with h/w decoding, mount points, charging
Untested: Bluetooth (turns on, but have no device to test it with), FM radio tested, but needs headphones as antenna
Not working / known bugs:
1. MP3, but plays FLAC – replace libstagefright.so from this link http://d-h.st/Zn6 in /system/lib/, set rw-r–r– permissions and restart the phone.
2. Color temperature changing in some cases - Replace /system/app/Gallery2.apk with attached Gallery2.apk rom the zip file and delete Gallery2.odex. Reboot the phone. Playing the recorded videos directly from the Camera leads to FC, but otherwise everything seems fine. This version is unaltered in any way, but fixes the nasty color temperature bug. FC problem will be fixed in the next full release.
3. USB Tethering – disable USB Debugging from Developer options and it will work
4. Contacts binding (don't have 2 SIM cards, so unable to test)
5. Search in contacts stops at 2nd symbol
※Please make a backup of your device before installing or updating ROM
