I flashed stock rom with Toolkit, many times wipe data - cache - factory reset - sd reset etc. But problem not solved. Tried 4.4.3 - 4.4.4 nothing boot system. Just stuck on bootloader animation or Updating system apps...

I can boot with 4.2.2. but just one time. After i reboot don't boot. Stuck on bootloader animation... If i do wipe, stuck at Starting System Apps.
Its something wrong with 4.4.3+ or baseband version idk. What can i do other than flash stock Google img?

Also sim card don't working... No imei no imei sv no baseband. 4.3+ don't boot. I really don't know what should i do.

Now flashed 4.2.2 (JDQ39) Google img with toolkit + TWRP 2.7.0.1 everything is Ok. Then flashed 0.48 Radio (Source: JDQ39). Nothing changed.

I also tried 0.84 radio.

And always boot takes a long time.

Maybe its hardware problem, how can fix it?

Try too when flashing 4.2.2 with toolkit changing your recovery to CWM. And it's not necessary to flash a radio after, the radio is included in the image.

If all else fails, take a look at this tutorial, in theory could recover access to your imei with it.

Good luck.

Don't know if it could work, but to have two mobiles with the same imei may be illegal.
