Ideally, yes. There's a pretty good chance that you'll run into issues with your lock screen, Samsung account and other apps if you don't.

Did you find any solution to this? Same happens here - once you've bootet to system (Realme UI) recovery is reverted back to stock.

I am not going to include recovery in this tutorial, you are free to choose what to use
Prerequisites:
Download SP FlashTool version 5.1916 (If you use another it probably won't work properly)
Download the old version of the stock rom from this link
Extract the Flashtool and the stock rom into your preferred folders
Don't forget to get the MT67xx preloader drivers
Don't forget to have adb and motorola drivers installed
Steps to unlock the bootloader:
Start flashtool, go to options and disable the option "check lib da match"
Select the DA (Download Agent) of the stock rom, also load the stock scatter and finally load the .auth that is in the stock rom
Start flashing the stock rom without first connecting your device, once you have used the download button you can connect your device, wait for the flashing to finish
Once the old system is flashed, disconnect the computer and go to fastboot (use the power and volume down buttons)
From fastboot use the command "fastboot flashing unlock" or "fastboot flashing unlock_critical" with that the bootloader is already unlocked, but it is necessary to flash 3 files to be able to use a custom recovery
To flash those files use these commands
fastboot flash lk lk.img
fastboot flash vbmeta vbmeta.img
fastboot flash recovery (recovery name) .img
Suggestions:
I recommend flashing dm-verity and force encrypt disabler (currently recoveries do not support encryption)
Once you flash that file from the recovery go to wipe, and from wipe touch the option "format data" and type "yes"

The drivers for this device are not installed. (Code 28) tried installing about a dozen drivers, do you have the specific one? for fastboot

Plug a usb cable at the phone to your computer and hold volume down and bixby and join download mode, at download mode you can go to Lineage recovery (repack that recovery.img into a recovery.tar for him) go to flash it in any slot BL AP CP CSC it don't matters he will flash to file namé partition, Pls clean flash rom with factory reset, or bootloop may occur.

I got the same problem with him, I cant enter recovery or download mode. I tried to enter download mode in various ways without success
Hello, A couple of regressions.
I have made a small investigation and now I'm sure that flashing BananaDroid is not a culprit of this "issue"
My ROM may touch only partitions which are fully recoverable by flashing stock ROM using PC Odin + potentially may touch EFS (if you e.g. forced to change CSC). I have a confirmed report that even flashing pure stock and restoring EFS backup created before I released BananaDroid for G965F/G960F did not help for this behaviour, so reason just CAN'T be dependent on this ROM.
Also, since we have not found any negative side effects of having this "bootloop" besides having to wait for battery to drain, install through download mode a ROM with the levels of **6*FXXU4DSAA or N97*FXXU1ASHE (if port ROM) (or just be on stock Android 10 already before flashing this ROM so your bootloader is actualized to Android 10) and you will be able to flash without trouble using your prefered recovery or Lineage recovery (verified working)
this ROM does not run any init.d scripts on boot, and also it does not include anything in ZIP install script that would touch your recovery partition or anything related to Mode Download, and as you can see above, some people have had success with the ROM, because the operation was not the same as what you did.
I'm on NobleROM before flashing your ROM
My step is format data, reboot recovery & sideload your ROM
When I hit reboot it stuck on bootloop and shows Galaxy S9+ but my device is regular S9
Now I can't enter download mode even after fully drained

Lets just say the issue is not great, about the boot animation, You should have only BananaDroid
If you have anything else than BananaDroid it has been installed incorrectly or there is currently brickwave and your device was flagged by Samsung Knox and has been disabled

I don't know <3 maybe Samsung Smartswitch software
As I said not my ROM has caused this because i'm not running a init.d that affects recovery or any partition like that, and i'm not running anything in my zip installer script either that touches those, recovery.img is included for only wireless update purpose.
You can try to take a thread about the problem and see if you can have more help of others to fixed it
For me the bootloader has a change.
