[Q] Re-unlock bootloader?

Already unlocked via HTCdev.
Locked it back for OTA.
I want to reunlock it. Do I have to fastboot flash unlocktoken Unlock_code.bin or can I just oem unlock as it's already been unlocked before?

So far i know
U have to flash the token again untill we have S-Off

You gotta re-flash the token.

You can unlock and relock many times, relock with the file sended by htcdev and relocked by: fastboot oem lock

RELOCK Bootloader -> UNLOCK BOOTLOADER

if i want to unlock bootloader again do i have to do all the steps again or unlocking or ?

Yes.
Sent from my HTC One X

If you still have the unlock token.bin you can flash that directly from Fastboot with the Fastboot commands, you don't have to do all the steps on the htcdev site !

Try EDL mode to flash the stock rom, search on google to find instructions, NEVER LOCK YOUR BOOTLOADER ON A CUSTOM ROM OR EDITED SYSTEM.

Question How to flash stock rom? I'm on arrowos 13, but my bootloader is somehow locked.

I'm currently on arrowos 13. I wanted to go back to stock rom. So I tried flashing the fastboot rom via Mi Flash Tool. I got an error saying my device is locked. So, I checked if my bootloader was locked by using this command on fastboot " fastboot getvar unlocked" . It says "no", which means my bootloader is locked. I don't know how that happened. I tried to unlock the bootloader with Mi unlock tool, but it fails at the verification step itself. I don't how to proceed from here. I'm stuck with arrowos now.

You can't install custom roms on bootloader locked device.
