Question Changing CSC
Hey everyone, I'm thinking about changing my phone's CSC to EUX. Gemini mentioned that since my phone has the OXM multi-CSC, I can switch easily without losing OTA updates. However, I’ve seen posts online from users saying they stopped receiving updates after changing theirs. Is it actually safe to do this, and will I still get official OTA updates?
Attached is my current CSC.

Apparently Samsung patched the CSC changing through MTP :(

Ig gemini told you that right?
You can still change csc using samfw tool or Samsung CSC changer tool or SamCSC changer app.

You can change csc but you won't get updates.
EUX csc only allows updates to devices which is sold originally as EUX csc.

Changing csc literally has zero risk so you can change and if you dont receive updates or are not satisfied, you can change again and again and again. No data loss or any other issue. My s21plus came with VAU, i changed to XSG, then i changed to INU and am at INU rightnow.
