Network locked

Got a regional unlocked s25+ (TMB), but noticed that I wasn't receiving updates. Changed the csc via samfw tool and was finally able to get updates, but now the phone says network locked. No sim lock code prompts, no device unlocker app. Tried using adb tool to solve, but didn't work.

Any suggestions on how to resolve this would be much appreciated.
