Hello,

is it please possible to change the CSC from ORS (SK provider Orange) to ORX (standard for SK)?

On S10+ it was possible just with flashing multi CSC ROM via Odin and a factory reset. Is it the same on S21 Ultra, please?

Thanks.

Both CSC's, ORS & ORX, are part of Multi-CSC OXM. If your CSC is ORS now, you can't change it to ORX (it's automatically set)

Well, I have ORS/ORS and ORS/EUX/ORS on my S21 Ultra.

I had ORS/ORS and ORS/ORS on my S10+ and I simply flashed a multi CSC rom via Odin and did a factory reset. The CSC got changed to ORX/ORX and ORX/ORS.

My problem with S10+ was that the simple ORS CSC has delayed updates by multiple months and they do not release every update from Samsung. The ORS is a customised anrdoid by Orange SK tele-provider.

After I changed the S10+ to ORX, I got finally the updates as the non-provider-purchased users.

That were the "good old days"...

Somehow Samsung changed this, and it's not possible anymore.

AUAC vs AUA4?
Anyone know the differences? I'm currently on AUAC
Also, is there an easy way to know which one is later etc?
