Hello Guys,
i have a redmi 5a and i made a rollback on rom from 10 to 9.
i had to unlock the bootloader and install previous verson of miui.
i could done that succesfully.
but i also installed twrp and root.
now i want to relock bootloader but when i do it via adb
not just the bootloader locks but the whole device too
and the phone does not start.
then i go back to fastboot and unlock the device with miflash unlock
and it works again but the bootloader is still open
what did i do wrong?
It's possible to relocked your device after rooting but relock the bootloader means locking the mod of your device, you'll lose your root. And again, if you need to root your device, you need to open the bootloader.
U cant relock the bootloader with custom recovery coz phone it doesnt start and maybe hard brick.always relock bootloader with stock recovery.also consider relocking,because u maybe cant unlock again until unofficial way found

Hi,
I just woundring if after unlock bootloader with HTCDEV is it possible to back to factory state with *** LOCKED *** status of bootloader again.
I think that it's not possible, but many times I read here on XDA it coud be done.
I know that it's a tool to lock bootloader from CWM - but if we LOCKED bootloader from CWM after that we can't reflash bootloader to oryginal HTC ( becuse it's LOCKED ).
If we first reflash bootloader to stock ( by fastboot) one we can't use this tool.
So the last way to lock bootloader is to RELOCK it afrer flash ROM --> BOOTLOADER --> USB FASTBOOT, and after that we have factory state phone, but the status of bootloader is RELOCKED.
Am I Right ? There is no another way to LOCK bootloader after unlocking to use OTA ?
I'm just curious.

If your wanting to relock the bootloader I would flash to a stock Rom using fastboot and relock after that.

What locking tool you using? That seems long to get locked status.
I know this is not a phone but I locked a bootloader today on a Nexus 7 by using the same shell I unlocked it with.
I might be getting my wires crossed sorry if I am. Glad you got it sorted though.

by the shell on WFS You can lock bootloader using the same metod like before to unlock of course , but when you do this the bootloader status will be **RELOCKED** not **LOCKED**, so of course RUU and OTA update will works fine but Warranty is lost.
If you lock bootloader with this tool ( superversion option ) phone status will be **LOCKED** and you be able to flash stock ROM and stock bootloader.
Hi I lost my phone but my phone is locked with samsung id. Just wondering if any one can install custom recovery and custom rom without unlocking or if bootloader can be unlocked using adb or fastboot?

it is not possible to relock the bootloader, from Fastboot directly ... The device will be corrupted later. To relock the bootloader, use the restore tool which will return the phone to its factory configuration ... Under ROM 10.0.7 .. The bootloader will be relock ... and all the data on the phone will be erased. It's the only way.

I tried re-locking the bootloader using fastboot and it happened successfully.
I am on Beta 2. It got successful because i haven't modified my system. Also it did wipe all the data.

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.
