Constant restarts on S21 ultra

[FacedCyber]

Constant restarts on s21 Ultra had to force a factory reset and still continues to crash. Factory reset returned an error

[libfs_mgr] Error updating for slotselect

Checking recovery logs found
Check_mdm_policy: /efs/MDM/FactoryReset does not exist. MDM allows factoryreset ( no such file or directory)

Can someone with the knowledge of what's going on help. As far as my phone is concerned it's bricked

Welcome to Android Central! Did this start after a recent system update? Did you modify the phone in any way, like rooting it and installing a custom ROM?

Here's the full last recovery log. The problem happened for about an hour the day before and last night it didn't stop. I'm not sure if it auto updated but it wouldn't allow me to check due to it saying the Sim card wasn't detected

Reinstall the firmware with Odin , which version you have international or US ?

 

[B. Diddy]

I made you the owner of the original guest post to make it easier for you to find.

That sure doesn't look good -- seems like either firmware corruption or hardware failure. Is the phone still under warranty? That may be your best option.

Let's see if @mustang7757 has any ideas.
EDIT: He already read my mind and beat me to it.

The phone hasn't been rooted or modified in any way

Correct

Look at the link i provided for help on this , get Odin and Frija the latest version from xda forums and when you extract the 4 files to put in Odin CSC use home CSC file in Odin so you dont need a factory reset

I successfully managed to use Oden and Frija and booted it up however the problem still continued after. Still doesn't detect a sim card or go without restarting long enough for me to make it past a few pages of the first time startup.

Sounds more like a hardware failure, then. You also tried Safe Mode? www.samsung.com/us/support/answer/ANS00062983/

Is the phone still under warranty? If so, I'd contact Samsung for warranty repair or replacement.

 

[FacedCyber]

Unfortunately not haha. I was kinda hoping to be able to fix this since I can't really afford to repair or replace it. I have a Samsung tablet that I'm going to swap Sims with to make due. It's crazy how it suddenly just started acting up too I treated this phone like gold.

Try once more to flash with odin but use CSC not home CSC so it can Reset the phone, if same after that it would need a repair shop

I've tried quite a few things already including csc and home csc, it's an att phone, the userdata I found from the fourms didn't work so I attempted the T-mobile one it worked. The problem continued however
