I found that also around the upgrade from 12.22.to 12.29 & then upgraded all the way to 7.1.19 to see if it got better & it didn't...So I gave up & moved to another ROM.

Hi,
It is very possible that the issue you are experiencing is because of a buggy unofficial Vendor/Shop ROM (8.0.3.0.0)
The extra .0 at the end of the version is what gives it away.
Shop ROMs can possibly contain Malware, Spyware & can have many bugs that don't get fixed because they never...
When updating all you need to do is install the .Zip & wipe Dalvik & Cache afterwards.
No need to wipe anything.
That's why you lost your apps & data.

It is most likely because you are running a fake/vendor ROM.
Flash one of the latest Global developer ROMs & then check under developer options for "OEM unlock" & "Mi Unlock Status" (add Account & Device)

Xiaomi only allows you to unlock your bootloader once every 30 days, that is why it allowed you yesterday but not again today.
Hope this helps everyone.

I have read a few posts on en.miui about this error message when attempting to "Add Account & Device"
This has been solved in a few cases by factory resetting the device & sign-in to.Mi Account during setup then attempting to "Add Account & Device" again.
Hi,
I have similar drops with this ROM version & same P62 baseband but I am using Redmi Note 4 (practically same hardware)
My only solution for the time being was to drop it down to 3G & only then it remains stable.
