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
to choose which model to compile you have to edit the file build.sh and change the variable MODEL (valid values are 990a, 990b, 980a, 980b, 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
for clean: ./clean.sh
