I am trying to return a Galaxy S4 Duos GT-I9502 back to stock, for someone who attempted to root the device, which failed. I am however experiencing some difficulty doing so, and would appreciate some help, if anyone has any suggestions.
This is the screen on the device:
I am able to put the device into download mode, though I keep getting this error message when I try flashing the device in Odin.
"Complete(Write) operation failed."
When attempting to flash the device, it quickly goes through boot.img, recovery.img and system.img (when it should take longer for each step, and you should see the little green progress bar move), before failing. Does this mean that Odin is having issues writing to the device?
I am pretty confident that I have the correct Samsung drivers installed, and I have tried completely closing all of the Samsung Kies processes on the computer. I have even tried using a different computer, and two different ROMs.
I have tried flashing the below ROMs:
I have also tried the 'Firmware upgrade and initialization' option in Samsung Kies, though I keep on getting this error message, before it closes (I do not know what it says, Google translate doesn't give a good translation).

Does anyone have any suggestion / idea of what is going wrong? Any help would be highly appreciated!
