Flash a custom rom with cwm..
wipe your data/system first.
wipe catche
install from sd card (Flashable file must be store in root of your sdcard.)
wipe catche
wipe dalvik catche
Imp:
Make your currunt working rom backup before anything you do with your phone. it will save you.

go to this post and flash the stock firmware via odin.
for installing custom rom, you will need root and cwm
go to recovery mode
choose install zip from sd card
choose the cwm file
this will install the cwm.
now wipe data and cache
go to advanced menu and wipe dalvik cache
then go to choose zip from sdcaed and select the rom
please make sure that you are using a proper custom rom file meant for your phone.
hit thanks if it helped

Boot Loop

When I was using stock RealmeUI (android 10) just looking some ROMs for RMX1851. And I've see Corvus ROM, just wanted to install my phone. I enter the TWRP and took a nandroid backup except data section and just deleted cache, internal storage, dalvik cache, cache and... vendor. Then I swipe to install and boom! ERROR 7. And I just wanted to back to stock ROM via TWRP nandroid backup. What happened? of course it didn't work. Nothing see wrong while restoring backup but the device doesn't boot up. I can still enter TWRP and flash somethings. And last thing is the build.prop file is not in their place.(/system/build.prop) Please help me.
Can someone take and share realmeUI nandroid backup please? This method might work.
Just flash realme ui ota file
Don't you think I didn't try that? It doesn't work.
