S20+ Ultra Crashing since OneUI 5.0 Update

[IbnSams]

Hi Folks - posting on hear as a last resort. I've had a S20+ Ultra for a while, and its been working great. Ever since the OneUI 5.0 update though its been rebooting, and often goes into multiple reboots. Have googled around and done the following things but it still happens!

1. Factory reset - twice
2. Removed all apps and using only core apps - still crashes
3. Booted into safe mode, multiple times it continues to crash

I have the latest 5.1 update on there too and its still crashing! Is there any advice you can give on what I need to do next?

Hi @IbnSams  It is advisable to wipe the cache partition after updates and can help with  instability/crashes.  Temporary files are deleted but  Data is  kept intact. Follow these steps:

1. Turn off the device.
2. Connect To Computer or plug in USB-C Headphones , Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release all three keys.
4. An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

can also Repair apps from the same Recovery Menu.

If does not help you may wish to send an error Report via Samsung Members-Support-Error Reports.   System logs are generated and can also attach screen recordings.

Clearing the cache partition did not do anything. Still crashing.
