I had rooted S4 Active (i9295) wit FW4.2.2 and wanted to flash stock 4.3. FW, then OTA to 4.4. I have several experiences with flashing FW. I think I'm on built MF3, but now I'm not sure now. My steps, that soft-bricked device:
-I unrooted phone in SuperSU, made factory reser and wiped cache
-I downloaded "I537UCUBML2" (4.3) Released 2014-01-07 - OFFICIAL
-Putted all files into ODIN 3.09 (BL,AP,CS,CSC), pressed Start
-Imediately FAIL! appeared in ODIN and this on display
START [224, 1440]
SECURE CHECK FAIL : PIT
When I turn it on, there is no logo, just blackscreen. But I can still go to download mode and recovery.
I dont know what to do now
Please, I will really appreciate your help...
Thank you very much!
