My S3 died last night. Stuck it on charge, under my pillow, like every other night. Woke at 1am to it very hot and stuck on the boot screen. Read around the net, deleted all data etc, tried a new firmware with ODIN, tried re-partitioning it, everything. Phone is dead, I can't boot into Recovery, I can only get onto 'Download' and even then ODIN won't work it's magic. When trying to stick a firmware on, ODIN hangs at "NAND Write Start" and when I try to re-partition it fails...
I think my phone has SDS...
