Dude it works perfect when you have some weird problems with the signal (? unknown) or imei (null/random imei) after flashing. You only need to re-flash unchecking all that options from your guide and then set the imei(s) manually. Always use the latest version of the program (Research Download R4.x.x for e.). In this version Calibration option is "Backup".

Thanks a lot!

Hello Hovatek.
I have done all that, and also tried a different pac file.
I'm facing the same issue.
And when I tried to flash one file at the time, I was getting this "Write flash failed".
Any suggestion, please ?

Note : The phone is Lenovo A388T.
