Samsung Galaxy S21 series, the same old thing again?

[kelvinti]

Hi bros, can i check whether we can flash Swiss (AUT) firmware with home CSC?
So far, i have flashed DBT but just wanted to check whether AUT firmware is also multi CSC and can flash on our phones without any issue.
Thanks

Yes! AUT is compatible! Nothing to worry!

Thanks Bro..
This one is to upgrade my Note 20 Ultra to Android 12.. I asked here because this thread is more active and have people who really flash their phone from different regions..

Comparing the CSC of OXM3 between XSP and AUT for SM-986B . They should be using the same multi-CSC firmware.

First full working day in office flashed with XSP BULC instead of the DBT. Batt set to optimized. At this time, still have 74%. Using outlook, teams and signal as well as some calls. Would say quite good, 5G network quite stable when switching to 4G.

Yes! 5G/4G switching has improved a lot. 5G cell strength and coverage have improved as well if the firmware does play a part in this mystery.

Use Frija, download speed is so much faster than sammobile.

I use the XSP version of BULC yesterday when I was back in the office full day. Compared to the XSP version of BUK8, it's much more snappy and batt saving. Somehow also resolved the 4G/5G switching too.

Performing a clear cache partition in recovery mode should help if you have not done so.

Anyway, I'm with M1 5G SA. No such telco problem. All are good.

Must off the stupid 5G. It's broken.

How is this broken? I'm using S21u with Singtel 5G, I don't experience any issue at all.

$4 button replacement from aliexpress.
It's so easy to replace no need to open the phone.

Saved like $80 from samsung service center lol.

I also replaced the power button to make it black as well since silver is sold out.

Yeah. The button is only to be inserted on the small square slot. The inside is well covered.

Funny! Singtel BULC look like XSP version to me, no more annoying Singtel apps. Singtel Dash oso not there anymore.
