how to restore to stock? Impossible

[hexen88]

hey

I just wanted to restore my s4 to stock cos im not sure why, but it isnt stock (custom system status) and kies doesnt see any updates. And I can't do anything.

current CSC is BTU, tried BTU rom from sammobile - cant flash - FAIL in odin
FAIL with PIT file too
FAIL to root (for changing CSC to XEO) - FAIL every root method I found - CF, Kingo, Vega, and with toolkit

Just - I can't do anything, can't flash with odin - always failed, with rom and root methodes too.
Can't root = can't change CSC
Can't change CSC = can't flash other CSC rom
etc...

Current rom: 4.2.2 official samsung btu
system state: custom
knoxa: 0x32
no root

any suggestions? I just wanted to update it to Android 5, maybe change CSC to XEO too - nothing more.

You CANNOT flash a 4.2.2. rom. You are already on a Knox bootloader. Why do all that trouble and don't you just flash a Lollipop rom if you just want to update?

1. Flash Lollipop rom.
2. Perform factory reset.
3. Voila.

99% of Odin errors can be resolved by different usb port / different usb cable.

I wanted to do that - downloaded newest BTU 5.0.1 - can't flash

changing usb doesnt help
