First of all, if you want to unlock your phone, check the date of manufacturing first! It is well documented here plenty of examples of newer phone brick when unlocking bootloader, so better be careful!
Secondly, if you ran into problem, you need to re-lock your phone using flash tool. Then re-unlock again! I previously lost my phone GSM radio when unlocking bootloader (while on GingerExperia). I have to flash into stock ROM (it's a must) using flash tool, and relocked again.
Finally, it is safest to unlock bootloader in stock rom.

No, you don't need to unlock it again. BL is the flash partition of the phone, what contains a secret code. When you unlock the BL, you'll remove the code and the flash partition will be open. When you flash a new ROM, it changes the system partition. When you flash a new kernel, it changes the flash partition but nothing else. So you'll not need to unlock BL again.

Can I install stock rom and bootloader locked??
Hello
Yesterday I've rooted my phone and then I wanted to install a custom rom (CarbonRom).
I've read that I have to unlock the bootloader for installing a custom rom. I did this with the flashtool.
After that my phone stuck in bootloop.
I have restored my phone with twrp recovery and it works now. But I still have a locked bootloader.
I have read that I have to install a stock rom to prevent a bootloop. I only rooted my device so my phone still should have the stock rom on it.
Does anyone know how to unlock the bootloader properly?
Thanks in advance
Hi all,
I have a Mi 9 europe version and want to get back to stock.
The current status of my device is:
- Bootloader unlocked
- TWRP
- flashed GSI FlokoRom
Can I just put the phone into fastboot mode and flash (10.2.24.0 PFAEUXM from there) with MI flash tool as mentioned there? Is it possible to relock the bootloader after this or will it brick my device?
I recommend you to flash rom WITHOUT LOCKING at first time. Even if something is wrong you should be able to flash twrp and then flash any rom.
But if after flashing your ohone boot up normally, flash it again and tick LOCK BOOTLOADER. Simple and secure way to get stock phone.
