can i flash latest stable rom via fastboot and set relock ? I read a lot about bricked devices during locking again

If you're device it's a china version china rom with locked bootloader if it's a global version device global rom with locked bootloader.
China version->China rom locked bootloader ok!
Global version->Global rom locked bootloader ok! /Unlocked bootloader=ok!
China version->Global rom locked bootloader =brick! / Unlocked bootloader=ok!
Global version->China rom locked bootloader=brick!

Please help me with my soft bricked Redmi k20 pro

I bought my phone in Aliexpress with global room. It had already unlocked bootloader and because of that my phone didn't pass safety net. So i wanted to lock bootloader.
I was following this tutorial: How to Lock / Re-Lock Bootloader in any Phone
up to 1:49 when my phone suddenly restarted and then this screen appeared: miui can't be installed on this device
And now I am stuck in this infinite loop. Can anyone help?

You locked your Chinese phone with the fake global rom? You can only lock a chinese phone with chinese miui, this is known.

Fastboot ROMs are used to restore soft bricked phones. Hopefully, despite your efforts, your bootloader is still unlocked.
Download a fastboot ROM from here.
https://forum.xda-developers.com/k2...irmware-10-3-8-0-9-6-13-t3939647/post79726515
Follow this guide here to flash it.
http://en.miui.com/a-234.html
In step 5 the options at the bottom of the Mi Flash Tool are set to 'clean all and lock' by default. This will lock the bootloader after flashing the official Chinese ROM. If you want a global ROM, then you do not want to lock the bootloader, you will need to change the option to 'clean all' before installing.
If you have managed to re-lock the bootloader and screw up the phone at the same time, then see this thread and read it all.

MiFlash Pro

Xiaomi tool for flashing your Xiaomi/Redmi phones:
https://miflashpro.com/
It's better than the standard MiFlash. Because you can flash the phone even without unlocked bootloader or if you forgot PIN/fingerprint/pattern in order to reset. Also it can automatically download the firmware for you. However, it does not delete your Mi account data. You need to login with your Mi account in order to use the tool with all options.
In case you experience any problems with latest version under Windows 8 or 8.1, first install MiFlashPro oldest version and then update to new version.

How to unlock bootloader on Oneplus Nord N100

Hello everybody
I need to know if there is a method to unlock the bootloader for an Oneplus Nord N100 but the BE2015 model (Metro PCS by T-Mobile) because I have not found out how to do it in this Forums
My smartphone is running Android 11 by an update (version 11.0.9.BE82CF).
My goal is to unlock the bootloader in order to install TWRP for a future custon ROM
Thanks to everybody and excuse my English.
Happy 2023

If I understand correctly you have to have the phone for 180(?) days and then "OEM unlock" will be available in developer settings. Then you have to request en unlock token from T-Mobile. (I don't have an american phone, I'm not 100% on the method)
You can get an unstable TWRP for this phone, but it will have very limited functionality. And custom ROMs is basically a forgotten dream on this phone.
Basically what you can do is sideload Magisk through TWRP (you have to use adb sideload command) and some people have installed GSI ROMs.

Really I bought the phone already unlocked, it has the "OEM unlock" function in the "Developer options". Because I didn't buy the phone directly from T-Mobile it's impossible to request the unlock token, so better I continue using it normally until I can buy another phone (I didn't comment but I live in Cuba...)
Thanks anyway for your answer...

I think you might be able to load a European/Global ROM through MSM tools. Then you can use OEM unlock command without token. Rummage through the N100 forums here and you can find guides.

I already searched and the ROMs are for BE2011/BE2013 models and mine is BE2015. My fear is to brick the phone in the process because it has a modified ROM especially for T-Mobile, thanks anyway

If all you want to do is unlock the bootloader I think you can just do this.
** WARNING: YOUR DATA WILL BE WIPED **
1. enable developer options -> oem unlock
2. start adb
3. adb reboot fastboot
4 fastboot oem unlock
if step 4 fails then try
5. fastboot reboot fastboot
6. fastboot oem unlock
The phone will show a screen to confirm unlocking. YOUR DATA WILL BE WIPED.
7. fastboot reboot
The phone should reboot. Unfortunately It will display an annoying message warning the bootloader is unlocked for quite a while before it boots into system from now on.
BTW: I had problems with twrp 3.5 for Nord N100 floating around these forums. Latest is twrp 3.7 which I'm still suspicious of. All of my flashing using TWRP on the N100 has resulted in bricking.
My successful flashes have been with fastboot.
I use TWRP on another phone and it works like a dream.

Hi,
In step 3, do
adb reboot bootloader
This will reboot in the ancient fastboot, not fastbootd. This is in this mode that you can unlock the bootloader.

Question System has been destroyed & bootloader locked because of DSU Loader installing

Hi Guys
Need your assistance, its a complete mess here.
I found android 14 pre releases in developer options -> DSU Loader -> Installed GSM+ARM64. Thought it will install android 14 pre release (Saw in one of youtube video -
).
Post restart phone it went to system has been destoryed.
1. OEM unlock option was not checked (Bootloader locked)
2. Only booting in fastboot mode.
3. Flashing through EDL/ Flash Auth not working.
I can only think of unlocking bootloader may fix this issue but problem is bootloader is locked. Can't unlock it because oem unlock is not enabled under developer options.
Please help me bypass OEM unlock check so that I can unlock bootloader & probably flashing TWRP or Orange recovery will fix the problem
Thank you

This tutorial is for those who have the bootloader unlocked (see the video at 3 minutes 38, the padlock is open).
What did you want to do?
The phone is bricked, nothing to do with the locked bootloader, see a Xiaomi repair center.

Hi
I missed that it is for unlocked bootloader.
So if bootloader is locked, it should not update the partitions & if so it should roll back to original miui if it fails.
But instead it bricked my phone.
So if someone can help me unlock bootloader I can try flashing recovery & then rom.
Or suggest better option. service center people asked to replace motherboard.

hi!
If there is any way to fix it, unfortunately it is paid.

It is imperative to unlock the bootloader with a xiaomi account where unlocking is authorized and associated with your smartphone. Without it, not worth it...
So unlock the bootloader and apply one of those countless FAQs that you'll find on XDA or youtube.
For me, settled in an hour.
Good luck,

What is the use of this post since the user has the bootloader locked?
