Recently i just flashed my i9070 to JB hongkong firmware (zsmg2),then i kind of feel that i prefer the old firmware rather than this version of JB,Before this i had use GB XME region..So you all know the issues of this hongkong firmware right,i had search entire site to find the solution on downgrading from this hongkong firmware,but still didnt find it..i tried to flash up with a custom rom but still the baseband and the imei appear to be 'UNKNOWN'..so i was hoping for the experts here to tell me the solution for this one.Please!!

Try to root and debloat, then try CoCore Kernel 8.x.

CoCore: http://forum.xda-developers.com/show....php?t=2140597

For the first time, download kernel, unpack, transfer kernel.bin.md5 to phone. Install Universal Kernel flasher and some root explorer (like ES file explorer or Root Browser) from Play store. Open Universal kernel flasher and install kernel.

For debloat look on links in this post: http://forum.xda-developers.com/show...54&postcount=3

ART is only available on KitKat roms.
