I have the i747, AT&T model of S3. The phone has been running without any issues for over a year. Currently, for the past month, I've had Task650 4.4.2 kitkat installed with all up to date bootloader, modem and TWRP (184.108.40.206). Today the phone suddenly died, and got stuck on bootloader image. Rebooting, removing battery doesn't work. When logged in to TWRP menu I see 0MB internal memory for some reason. I re-flashed the TWRP, reformatted internal memory and still no go, 0MB. Is there any way to get it back up or is it completely hosed?
