Unrooting from CM 11 after a previous stock 4.3 OTA update - NAND Write Fail!! topic

Hi Guys,

I have an unlock code from AT&T and I want to use it from the Stock ROM. I am currently running CM 11 nightlies.

I tried the standard method of using ODIN from PC to flash stock ROM. It doesnt seem to work. I am always stuck in ;NAND write Fail'.

Before installing CM a while ago I updated OTA to 4.3, and based on what I read everywhere this seems to have something to do with the issue.

Any help on how to proceed will be great.

I am using ODIN 3.07
Downloaded Stock ROM from sammobile.

This is what my download screen reads.

ODIN MODE
PRODUCT NAME: SGH-I747
CUSTOM BINARY DOWNLOAD: Yes (2 Counts)
CURRENT BINARY: CUSTOM
SYSTEM STATUS: Official
QUALCOMM SECUREBOOT: ENABLE
Warranty Bit: 1
BOOTLOADER AP SWREV: 2
SW REV CHECK FAIL: Fused 2 > Binary 0

Thanks!
