[Q] [PICS] Stuck on "Firmware Upgrade Encountered an Issue" [URGENT]

Silotolis said:

Hello XDA, haven't been on these forums for a while.

I have a slight issue with a Galaxy SIII I just picked up off a friend.

The S3 goes to this screen every time I try to boot it with the power button:

And I AM able to get to the download mode screen:

I've tried to flash a Stock Rooted Firmware onto the phone using Odin 3.07, and all it does is say it failed.

Another thing to note is that I CAN'T boot into recovery, and that I do not have Clockworkmod installed.

Also, I am not sure if my device is rooted as it was given to me by someone else..

Any help on trying to solve this issue will be much appreciated!! Thank you! ��

EDIT: if you can't see the images for some reason, it is just a photo of the "Firmware Upgrade Encountered an Issue" screen and a photo of the download mode screen.
