Samsung 20 Ultra (Failed to update)

[manty]

So my device just downloaded the January patch, it started installing it and just flashed error and the phone booted up like it was finished. The device optimized apps and then an error popped up 'Failed to install update'. Should I be concerned?

Turn off the phone. Then connect it to a computer (still off), wait until info about charging is displayed and thed press volume up and power buttons and holt them until Samsung logo appears.

Then the phone starts info recovery console.

Select menu Wipe cache partition (use volume buttons to move selection) and confirm pressing power button

Then select menu Repair applications and confirm.

The phone will restart and process again applications optimization.

Data will not be deleted, only caches.

If my answer was helpful please set it as a solution, thanks.

I followed your steps but the update isn't there to download anymore but shows Security patch: 1 January 2021, but I don't think it's installed

Updates depend on your model of device, S20 Ultra in your case, and your CSC code.

Could you post your CSC code.

To locate your device's CSC, (Consumer Software Customization), code, go to...

Settings > About phone > Software information > Service provider software version (see screenshot)

The steps should have to fix applications

Here it is

[ironass]

That is the stock, non-carrier, CSC code for the U.K.... BTU, and is eligible for the update. 

As Libb states in his previous post, the instructions that he posted earlier should have fixed the issue. Perhaps running them a second time may help.
