I flashed my S9 to a U1 firmware using the patched Odin 3.13.1 and it worked fine. Now I'm trying to flash back to the U firmware and it's sticking on file analysis. I've tried changing ports, cables, I re-downloaded the firmware, the bootloaders match, but nothing works. I tried a different Odin and they go but they fail. I tried the 3.09, 3.10, and 3.12. I would stay on U1 but it has the same issues as U and using the phone gets stuck on the phone unless I restart the phone itself.
