The first thing that you can do for us is to get us the libota_jni.so
This will not help you in the least but it could help someone with a P6Pro.
Have you enabled ADB yet? Get that working.
Code:
adb pull system/lib64/libota_jni.so
Zip it and post it please.
Then you will need to get conversant with EDL.
You can install a custom recovery that can install the Palma2Pro software.
