Ported a rom successful from mobile with the exactly same specifications with mine, unfortunatelly the power key does not trigger screen lock and unlock, what to replace to make it work? Plus when the phone goes to deep sleep it takes ten to twenty seconds to come back on when power key pressed, please advise thanks.

The importantly for fixing is in system/lib. Theres so many bug when first time porting a ROM's and lib is the first to solve that bugs. Trying to replace the lib files from Stock ROM to your PORT ROM but not all. Just replace it one by one. If it makes your phone bootloop, the lib files is not compatibility with your PORT ROM's. And especially don't forget to backup the lib files before replace it from your Stock ROM.

Hope it helps

I ported CM10 for my mtk6592 and there's just one error, when I put a number in dialer app and click on call, it says "searching for networks" and it remains there. However sometime it calls. And it can receive calls from other phones.
Copied all the SIM1/SIM2 files from base to port and the firmware folder and everything but its just not working.
And no apns are being displayed in settings.
3g turns on and displays "3G" on statusbar but net doesn't work.
Have copied apns_config but still doesn't work
Do you have any clue how to fix?

In system/framework, you can replace telephony-common.jar and telephony bla la. And in the system/lib replace all file with the name of "ril" and in system/bin replace it too the file "ril" to your Port ROM from Stock ROM.

Hope it helps
