TLDR: Odin says it flashes recovery successfully, it doesn't seem to be working.

Note 4 was damaged and brought out the S3 for a temp backup phone. I activated it, made some test calls everything worked great. Came back a couple hours later to the phone in download mode with a red error stating it could not normal boot. I attempted to go into recovery, pulled up TWRP 2.6.0.0 with a password prompt but I've never set one. I googled the TWRP issue and there was a problem with Sprint GS3 and TWRP, I loaded up Odin 3.0.9 and attempted to flash a newer version of TWRP as my searching had recommended, Odin flashed, said PASS! and I rebooted but it was still on 2.6.0.0 requesting a password. I pulled up ODIN again, tried CWM/Philz/Stock - same issue still TWRP 2.6.0.0 even though ODIN stated it successfully flashed. Tried a different computer, a different USB cable, same issue. ODIN states that it is successfully flashing but it doesn't seem to take. Then I tried flash stock ROM, got an error in ODIN this time, stating it couldn't write, googled that was told to get a pit file, that can't be written either.

I can't seem to find many people in my situation, was hoping I could get some input before I started buying hardware to try to fix it (JTAG and micro SD/linux solutions).
