New Update UI 6.1 touch screen unresponsive on S21

[MPopescu]

After installing the latest update on both phones (S21 5G and S21 5G Ultra 512 GB 16 RAM) the touchscreen became unresponsive. I noticed that the date automatically was changed on both phones to 3rd May 16.00.

The only thing that is working are sides buttons. 

I managed to start the recovery console using:

 1. Side button + Volume down to restart the phone

2. Then very quick I change to Side button + Volume up

I wiped the cache partition and also performed a factory reset on S21 5G but unfortunately did not solve the issues. The only change is that the phone is starting the setup (with a padlock locked on top left corner) a new phone but I cannot interact to set it up.

I assume that the main and major issues are with UI.6.1

Is there anything I can do for downgrading the android/UI and recover the information I have on S21 Ultra?

I hope that there is a quick solution as it is so frustrating for having two top phones and to not be able to use any of them. At the moment I'm lucky to have an A70 with older android and UI but I'm thinking of leaving Samsung after many years and products and not buy any other.

Thank you.

Thanks for the solution but in this video, Its clearly mentioned that its risky as it can destroy your phone. So why I will take that much of a risk for Samsung's blunder in this new update.

They made this update and now they are responsible to solve our problem as I was not begging for their phone to give it to me for free, I purchased it.

We all gave our money to them and now they have to fix our problem. This is their responsibility.

Good afternoon everyone,

Thank you all for your great support and for sharing potential solutions.

Regarding the YouTube solution mentioned above, please is good to be aware that in some situations, it could be a real disaster and damage your phone.

However, I have tried multiple times to update my Samsung S21 Ultra 5G using different firmware, but my phone is still frozen but not completely broken.

As mentioned by someone else, you cannot downgrade the firmware version.

My phone (Samsung Galaxy S21 Ultra 5G SM-G998B) was updated through an automatic update pushed by Samsung to the latest UI6.1 (11/RP1A.200720.012/G998BxxSBGXDH).

The fifth character from the end is the Bit/Sw rev number (in my case B).

After looking on the SamFw website, I noticed that this is the last version for multiple carriers worldwide, so you should carefully select the correct version and firmware/file.

The files from the firmware update are:

- AP: system partition with recovery and other components

- BL: bootloader

- CP: modem

- CSC: contains customised settings, system configurations, localisations and geo-specific things such as the system language, APN settings, and carrier branding

CSC is essential and will cause a complete wipe of your phone's data, while using home-CSC will not reset your phone completely.

In conclusion, if there is a previous firmware with the same Rev/Sw number, you have a chance to repair your phone.

Otherwise, you'll have to wait for the next update from Samsung. In the meantime, I have already switched to Apple, and Samsung should really work hard to change my mind. I was hugely disappointed to lose access to such an expensive phones.

I think any purchase from Samsung is risky 

[Mohamed Hashish]

The devices are stopped and there is no support 

[Mohamed Hashish]

I bought the phone from Noon store 

And while the settings were working, I updated the phone 

And it stopped working before I used it.

If your device is new you should ask for being repaired or replaced as I assume that you're covered by the warranty policy.

How many users are being affected? How is Samsung not even responding? It is illegal.
