This is based on Quarx's repo (seems abandoned?), build with recent updates.
2.6.32 kernel updated to AOSP Android 4.4.1 (most parts of the system) all hardware-related fixes in Quarx cm11 build app2sd fixed add apn list (aosp specific) chromium black box fixed (aosp specific) full language support low_ram flag enabled by default, toggle with AeroControl no defyparts, replace your own bp_nvm_default before flash no fm trimed ringtones
common bugs of defy 4.2+ (bt headset, no phonecall sound when bt enabled, mute mic...) panorama not working wifi-tether not working occasional graphics glitches you say ;) expect to have less random bugs than cm, or more
Because there are problems that I can't fix.
* frameworks_av -need-> frameworks_native -need-> system_core --> hang at boot
stuck after green led, adb cannot connect
tried re-apply this fix, didn't help
*frameworks_opt_telephony --> broken mobile data
will be glad if you would like to help
Thanks to TJKV for guidance and of course Quarx for his fundamental work.
