S23 Ultra 6.1 update rollback is possible.

[Sayam_Hossain]

Current bit number is 3 for Asian devices, 

You guys can roll back to 6.0 or even to 5.1 if you want as the bit number is still "3". 

You can downgrade till August/2023.

Why? You want to rollback?

Till now, I think 5.1 is the Best, android 13 is good.

[Sayam_Hossain]

No. I am just letting people know that if they want. They can roll back

[Mayur000]

How's that possible?

[Sayam_Hossain]

With SamFw tool. But I will erase all of your data...

[Sayam_Hossain]

Matching bit number is very important though.

Visit Samfw... search your model no. Then select the country as per model number, then you can download it...
Flast it through odin.
