ZOPO kernel source code (unofficial)
ZOPO has never released the kernel source of ZP980 and ZP990 I managed to compile a compatible kernel using the sources of different phones (iocean and yaiyu) (original development discussion: http://www.androidiani.com/forum/zopo-modding/409433-zopo-980-990-c2-c7-wip-sviluppo-kernel-sorgenti-compatibile-con-kk.html sorry is in italian)
first of all thanks to dr-shadow (https://github.com/Dr-Shadow/android_kernel_mt6589) for his kernel source that I used as base
this kernel is compatible with ZOPO model: 980, 990, C3
for the 980 and 990 there are variants that differ in the accelerometer sensor, try first with the A version...if the rotation of the screen (in landscape) is upside down recompile with B version
you also need to edit the path of toolchain
feature included: selinux enabled, binder.c patched for KK, sweep2wake and doubletap2wake, various tweaks
for compile: ./build.sh
to choose which model to compile you must specify as a parameter for build.sh (valid values are 990a, 990b, 980a, 980b, C3)
./build.sh 990a
./build.sh 990b
./build.sh 980a
./build.sh 980b
./build.sh C3
for clean: ./clean.sh
