Hello there,

I want to port the J120W firmware (Android 6.0) to the J120x phones (Android 5.1.1). I have both firmware files and I only see a difference in overall size of the partitions.

After updating my Android Dev Tools I've fixed CSC, boot.img, and system.img. I don't know what to do with the J120W references in the configuration files, I could change those to refer to any other J120 model. Nonetheless I want to test the firmware without said changes and see what odin, or hopefully logcat has to say. The firmware "should" be ready to flash, but I can't seem to find the phone to do so.

If you want to help beta test the firmware, hit me up.

Update: It works!, It's booting up!. Bluetooth pairing and 4G support both seem to be broken. I think I can easily fix that.

Not yet, I've tried many things but both Bluetooth and 4G are broken. It also has wifi and battery problems.

It seems like these problems can only be solved by making an appropiate rom from the extracted resources of this firmware. The problem is that I don't know how to do that. I've tried before to no avail.
