DESCRIPTION
Update 15.01.2014
Fixed color temperature bug (please see #2).
Alpha version
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
Good work man. Testing your ROM!
Installation aborted why??
You need a proper CWM. Use this one: http://d-h.st/QxB . Rename it to recovery.img, place on sdcard and flash through MobileUncleTools (install from Market). This is the easiest way, but you need to be rooted.
My instalation was also aborted…
It's a safety measure, so people will other phones won't be able to install it.
Hi Infrared… what is the difference between this one and your other ROM (which is soooo popular ) ?
Ohh… I get it. This one is 4.2.1. Sweet.
Tried using TWRP also installation aborted!!
Then it is not properly modded. It fails on the first line of the update script
assert(getprop("ro.build.device") == "A820" || getprop("ro.build.product") == "A820");
had no problem with TWRP til now…don't really want to flash CWM is the ROM not compatible with TWRP? frustrated really want to give this a go to compare with the recent baidu rom!!
not properly modded??
Yes, it does not have A820 device strings. Open the archive and copy updater-script file outside.
The file is in META-INF\com\google\android\
Then open the file with text editor andremove the first line. Copy it back to the archive and replace the original file. Don't exctract the whole archive. just the script.
tried that infrared….didn't work my friend:"error executing updater binary in zip"
you edited updater-script, not update-binary, right? Will upload another verions without the check.
yes edited updater-script got error message…come on infrared can't wait to give it a try
Thank you infrared forma your help
