hey, i have an LG optimus G 97310H i have rooted my phone but now i must send it away as it is having hardware issues.
i used superSU to permanent unroot. but for some reason SUPERSU PRO is still in my applications list.
and it dose not give me an option to remove just Enable OR DISABLE. so what im trying to do is remove it. so i thought if used KDZ and installed the official ROM. i downloaded the ROM from 2 sources. and when ever i put my phone in download mode. KDZ gives me this error.
"File Extract Error."
"Finished"
any help on how to fix the KDZ error. or if i can remove the superSU another way?

**** its also not a custom ROM installed ***

I see no any reference between "File Extract Error" and "different usb port"

.KDZ is an archive, which will be privately unpacked by update tool and if the checksum of .dz (or .tot) is ok, flashed to the device.

"File Extract Error" means .kdz unpacking went wrong.

Any updates for this issue? I got a LG Optimus G Pro F240L from south korea and it is stuck in download mode. Everytime I use KDZ updater I got the same error: Extract File Error

Since it's a model less common I managed to get the KDZ from only one place (lg servers).

Need help lol!

Tablet KDZ unpack error
Have the same problem. Mine is Optimus G E977. I download 4, Official KDZ stock from LG Firmware list and very one gives the same error. I try to donwload again, and still the same error.

I also have a Optimus L7 and KDZ update function flawless. Maybe it's because the size (more than 1 gb).

Would appreciate any help
