Hi guys,
I have a same problem. I can't flash my S4. At time I have Android-Version 4.4.2 KK, but I want to flash 4.2.2 JB. I found at Sammobile the firmware, what I need and downloaded it. I set my phone in dowload mode, chose in Odin the right firmware and clicked on start. After a few seconds it failed with the message aboot.mbn write protection failed. Well, I removed aboot.mbn in the tar.md5 and tried it again. Nice! It worked, BUT when I started the phone there was a black screen with an triangel between a mobile and a computer symbol with the message in red in the left corner on the top: Secure Fail: Kernel. If I choose Firmware with the Android-Version 4.4.2, the flashing works nice. Why it doesn't work with other versions? Need help!
I'm looking forward.
Best wishes
David
