I've had my S3 for over a year now and it has been mostly running great. Whenever I've had issues I tried to solve them by myself, but this time I was unable to fix my phone, so I must ask for help.
Here's what happened. I left my phone on my desk today and one of my co-workers fiddled with it. He opened SuperSU and then a message popped up saying that SU binary needs to be updated. He then choose to update it via CWM. The phone then restarted and upon starting shows the startup screen then it tries to enter the recovery, but instead it just shows it for a brief moment and then it restarts again. It keeps doing that over and over again. If I remove the battery and then insert it back again, the phone will turn on by itself and continue to reboot after failing to open CWM.
I tried to enter the recovery, but had no success. The phone did enter the Download Mode though, but flasing a ROM via ODIN will remove all of the data stored on the phone and I really need it. The phone is currently running Android Revolution HD 40.
Is there a way to get my phone operational again without loosing the data stored on it?
Thanks in advance.
