SKEY: 42310316
BKEY: 8F8E94E605D68332D43526391A7EBD34
The all dependency is corrected, but SKEY and BKEY not working to be writed in your phone...
So, I suppouse to your bootcore is wrong (HASH) after trying to unlock your phone with testpoint.
You need to flash your phone (included bootcore area) with good fullflash file and after unlock it with the following steps:
-open papuautils ( I suggest to use the version 1.1.1b or c).
-go to the "Codes" menu and write in the SKEY case any key with 8 numbers.
-go to the "Flash" menu and set COM speed to 115200, CHECK ONLY "??????OTP", "in Flash" (Recalculate Keys -> automatically wil be checked other three options) AND "Pause" (verry important!). OTHER OPTIONS NOT BE CHECKED!!! Select Phone "C72".
-click on "Do the Job...", push shortly power on button (from the phone) and wait to finished.
After message "Close all connections" your phone will be unlocked. Enter in Service mode to verify if appeair message: Phone is in "Service Mode". SecurityStatus: "FactoryMode"....
