[POCO X3 NFC/SURYA] System is unstable: Black screen, lags, stuttering and bugs

[Allenzoko]

System apps crashing, settings app doesn't work, system-wide lag and stuttering.​

First, I'm using the latest V14.02.​

I've recently come back to Xiaomi.eu ROM, because the system integrity bypass method is basically the best and my banking apps keep demanding a lot of things to work.
The problem is that ever since the first boot, I'm encountering sudden crashes, black screens, unable to set up fingerprint unlock, and it seems that everything settings-app related is buggy.

​

I cannot:​

— Set FP properly;​

— Set themes​

— Close apps in tasks​

— Setup system preferences;​

— Download backups without crashes;​

— Download WhatsApp backup;​

— Connect to PC properly (it crashes randomly);​

And everything system-related.​

I did format all needed partitions and format /data with the “yes” option.
I did it twice and can't get it to work properly.

As always, if need be, I'll try to get some logs if devs deem necessarily.

Thanks for your hard work.

A bit late, but the best thing to do in that case would be to start clean from a miflash installation

I'm doing for the third time in 45 days. The system will bootloop after some time.
