I've been crawling the net and forums to try to fix this problem of mine but not sure what else can be done.
Some background to my issue.
My S3 has been in cold storage for awhile and last booted it up back in March after doing a stock firmware OTA update to 4.3 after a factory wipe. Everything was fine and dandy then.
However, when I booted the phone up a few days back, it was stuck at the splash screen and when I went into recovery mode to try to do a factory reset to see if it helped, I kept getting mount errors. I tried using odin to reflash the phone with the stock 4.3 firmware but the problem does not go away even though the flash goes through successfully.
I have since installed the CWM 22.214.171.124 and did a 'mega wipe' of the phone and tried putting in an alternate rom in cyangenmod 10.2 but the mount errors are still there.
I have attached the screen capture of the issue I am facing for reference.
Any advice to resuscitate the phone will be gladly appreciated.
