I've tried to change imei with original firmware:
I8262XXAMJ2_I8262MTLAMJ1_I8262XXAMJ2_HOME.tar.md5
result was:
Waiting for phone...
Checking if phone is Rooted...
Root Access Granted!
Waiting for phone...
Preparing phone. This may take a while...
Resetting IMEI...
Rebooting phone...
Waiting for phone...
and phone not powering on.
After flash with the same firmware phone power up, but both imeis are:
0/01
0/01
After that I've tried flashing:
I8262 Special Firmware For IMEI.tar.md5
phone powered up and I proceed to change imei,
same situation again, nspro stops at:
Resetting IMEI...
Rebooting phone...
Waiting for phone...
and phone doesn't power up.
So I flashed it again with:
I8262XXAMJ2_I8262MTLAMJ1_I8262XXAMJ2_HOME.tar.md5
Phone powered up and voila - both imeis are changed correctly
P.S.
All these test are done with latest nspro version: 6.7.0
If you need more info or tests, pls don't hesitate to contact me.
Regards!
