Hello, 

I am currently running One UI 3.0 First Beta and today I've received an new update when I try to update it restarts the phone then gets the 25% on updating then it says error then boots back into normal saying failed to update firmware

This has happened before, if you just wait a day or two then it should work.

do you have enough free space on your internal storage? Also ensure your device is on a totally stock firmware.
