S20 5G ULTRA No mobile network after july 2022 update

[NickLaz]

Hello,

I have an issue that I've been working on for 2 months now and I found no solution. 

After the july update my Samsung S20 Ultra 5G cannot connect to any mobile network.

I got this sign!

Of course I did all the basics and advanced recomandations but nothing works.

The only thing that worked only one time was the factory reset. Unfortunately the phone managed to do a new update and the problem comes back.

Now when I do a factory reset, I got a message telling me that I've done an unauthorized reset and the problem persist.

So this is not an hardware problem, the problem comes with the update. And I cannot downgrade to get back to the working state, it seems to be impossible!

I'm desperate because the phone only work with WiFi wich is not the first objective of a phone, I cannot even make a phone call or receive a message. 

So is there anyone with a real working solution and not just remove sim or change sim, restart phone,  reset network, clear cache, factory reset, adb command line, odin firmware loader etc...

Thanks a lot.

Best regards.

I'm assuming you already tried using the same SIM on a different device? And I'm also assuming you've performed a Wipe Cache Partition? If yes, I would take this unit to a Service Center soon.

Your device was somehow factory reset protected (FRP). Assuming hindi mo ninakaw yan ✌️, this tool should work to remove FRP: https://samfw.com/blog/samfw-frp-tool-1-0-remove-samsung-frp-one-click

Maybe a SIM card problem?????? Maybe try it on another phone.....Or check your SIM card tray. Even if the SIM card is removed, it should still show a Emergency Bar. And not a BLOCKED logo. Oh wait, your SIM card might be blocked. Try another SIM card.
