ALWAYS USE DOWNLOAD ONLY MODE OF SP FLASH TOOL.
DON'T TOUCH ANYTHING RELATED TO FORMAT ON SP FLASH TOOL! (IT'S WRITTEN EVERYWHERE, YOU WILL LOSE YOUR IMEIS IF YOU USE FORMAT ALL + DOWNLOAD. YOU ARE SAFE IF YOU USE DOWNLOAD ONLY.)

  • Select all the Partitions except opporeserve2 and cdt_engineering. otherwise you will get errors.

Again Make SURE "Download Only" is selected. Don't select ANYTHING ELSE! You will lose your IMEIs, Serial Numbers, Capability of Hardware Attestation etc. if you choose "Format data + Download" make SURE you selected "Download Only".

After flashing it should look like this. Download has been complete. Enjoy!

Realme 8
Some people having this problem so I want to add one more thing to the guide. If you are not having any issues related to boot then don't follow these steps.

After waiting more then 10 minutes, if it doesn't boot up/bootloop. Or shows DM-Verity corrupt error then do this.

1) Try boot into stock recovery by pressing volume up + power button after that when your screen flashes quickly unpress buttons.

2) Now press volume down + power button, by pressing these you will boot into stock recovery.

3) Go to format option and do a full format.

4) Your phone will definitely boot up after that.

if "Brick" occured in rooting process - then can recovery be done without data loss :

Prerequisite: firmware version on the body must the same as downloaded "Decrypted OFP" (as example both is A.22 )

HowTo:
at step of SPFlashing (currently that is 10-th)
- check ONLY next partitions in SPFlash to restore :
PRELOADER RECOVERY VBMETA LK LK2 BOOT
... and NO any of other
(as thats only are touched by currently described rooting processes)
 
Ok. format from recovery menu solves ...
now that boots normally =
- no alert
-no boot allowing by pressing key required

good behaviour to see when boot subsystem altered, as at every boot alerted and required to press longer power button to confirm/allow starting ...
interesting, that is something new on mine (device versions) or overall ...

I have it anyway. have you solved it yet? Do I understand correctly?
I Think that is not so solvable /possible if someone decode debug and finds /... but that is quite acceptable for rooting /if you don't want to make illegal spionage and so on/ ... also as if your device will be rooted by someone - you will see alert of changes on boot ... that is good ...
if you are rooted - you must be alerted .

but if you will going to stock rom and have protection - then flashing "stock" (surely without 3 partitions that IMEI-and-so-on-related ) and then format from recovery menu helps return to "factory" operation

Maybe you missed some step. Can u explain ur problem briefly. What u did and what happened.
just a casual day to update my firmware, reboot and my phone refused to boot anymore, and then i came here, following all the steps very carefully (i read every steps twice so i dont make any mistake), and no luck.

on your firmware package, it does not flashes super.img by default. Because in scatter file
- partition_index: SYS48
partition_name: super
file_name: super.img
is_download: false
changing false to true helps fixing destroyed super partition

    Does the phone warranty will be void once the brom.bat ends its work?
    The warranty will be valid.
    If you want to return the phone to the service, lock the bootloader and say that it is after the update.
    They will load original system and after problem data will be lost
