The first time you unlocked the device the .bin unlock code was send in your mail box, check if its there. If its there you copy it to the fastboot folder (or the folder where you flash from)
Phone in fastboot usb mode and do this command
Fastboot flash unlocktoken unlock_code.bin
This unlocks the bootloader and you can start flashing

Bricked with access to only Fastboot in oem locked state

A chain of unfortunate(or reckless) events led to my soft bricked Robin. This is the current state of the device:
Does not boot normally, stuck at boot loop.
Have access to fastboot mode and Stock recovery.
No access to adb.
Device is OEM Locked and does not allow flashing anything from Fastboot.
What are my options? I have seen posts for other devices where they toggle OEM Lock status from Fastboot
Also some other cases where they use QFIL to flash stock OS.
Please advise.
Can unlock the boot loader with
Code:
fastboot -i 0x2c3f oem unlock
Did you get the drivers n stuff?
(apologies if you know all that).

How to stop Stock ROM overwriting the Custom Recovery?

I was trying to flash a Custom Recovery(TWRP) on my Friend's phone(Realme 3) It was officialy supported by TWRP and was listed on their website so I downloaded the Custom Recovery. Then I unlocked the bootloader of his phone but yes a strange thing happened there after it asked for pressing the volume button to be pressed it unlocked the bootloader but after that there was option "Select boot type"(Not sure what it said). It had three options Boot to Bootloader, Boot to recovery and last Normal boot and also there was a arrow on the bootloader option. And there were some instructions something like volume up for select and volume down to move. But I tried every button but the arrow was stuck on the bootloader option. So I connected it to my device and used the "fastboot reboot" command to restart the device after restarting at the realme logo it was saying "You are unlocked you cannot be trusted" But after it booted normally and the phone was Factory Reset. After this in the Developer options the OEM unlocking was grayed out saying Bootloader is unlocked. Ok so we were successful in unlocking the bootloader. After that I pasted the twrp img file in the platform tools directory and put the command adb reboot bootloader and after the device was in bootloader I used the command fastboot flash recovery name.img to flash the recovery. It said sending and then writing in my terminal after that I used the command fastboot reboot and the the key combinations(power+volume down) for the device which used to get into recovery for that phone but this time instead of going into recovery it was in the bootloader. So again I tried fastboot reboot command and this pressing the power+volume up but the phone booted normally so this time I tries adb reboot recovery but it booted into stock recovery so again I tried flashing the recovery and tried using fastboot reboot recovery but it didn't work. And yes I know that after flashing the custom recovery the phone should first boot into the recovery but as I said neither the key combinations nor the fastboot reboot recovery command so what can I do to prevent the system from overwriting? PS: Sorry for long paragraph...
