ProxyBiohazard , was the v9.0.48 version the original installed firmware before you flashed anything?
If so, then likely your player would be the ATJ209* series, and you'll be needing the v9.xx firmwares here

It is not possible to identify which particular firmware would work with your player fully, so you'll need to try all of those for your screen size until you get one working. Good luck.
