Thank you very much!
I fixed it!
I restored my old files modem1st and modem st2. After i'm restored QCN backup (with the help of your file). And, before reboot, was loaded QCN file from firmware (WBW8901GI_0301).
I'm used QPST 2.7 build 402. Only this version, 402, has helped me!
I'm happy!!! Yeeeah!!! Thank you for help!!!
What about me - i have a bootloop after restore on 4.2.2 firmware, and "unknown" IMEI, network and other on 4.4.2 firmware... I can restore IMEI, but i have not gsm/umts network signal.
If you get a working phone - can you make a backup memory of your phone (without userdata, system and other your private files) with "Partitions Backup&Restore" (from market) ?
I think my problem - the consequences of my "experiments" with memory...
in developers menu you activated "write diag interface" and debug via usb?
