BUG FIXING
If you found any bugs repalce from BASE to PORT
Bootloop?
Replace following files(from stock to port):
Code:
libandroid_runtime.so
libandroid_servers.so
libmedia_jni.so
FOR CAMERA NOT CONNECTED ISSUE / CAMERA GREEN / CAMERA FORCE CLOSE "unfortunately camera has stopped"
No success after the files replaced above then keep on replacing one file at a time and check.
Camera problem is the one major bug in this type of porting. You have to have patience. This will take half of your energy.
Replace all "libcam*.so" files from stock to port if even after trying these files camera can't connect (It may lead to bootloop if ROM boots successfully)
Another fix Init.rc (very important)
Unpack port boot.img and stock boot.img
compare the init.rc file inside extracted boot.img and find (ctrl+F)“cam”. Copy and replace ALL lines related to camera from stock boot.img to port ROM boot.img.
