How to unlock bootloader and install EU Rom ?

I don't have my Mi Max 2 by now but i suppose it works like this:
1) Unlock the bootloader officially (there should be some tutorials for this as it works the same on all mi phones)
2) Download an adb/fastboot package
3) Download and flash TWRP (http://en.miui.com/thread-644074-1-1.html)
4) Start TWRP (Turn phone off and then hold Power and VoL- (or VOL+ - not sure) i think) and flash ROM, then SuperSU. Maybe you have to format data first to get rid of the encryption
5) done

I've got my device with unlocked bootloader. So no need to unlock again. Tried to OTA update, but never successful. Then tried flash global update rom manually from twrp (have to install first). Now I have latest update global rom abd of course with root (for some system mod ).
I don't know how to back to stock recovery and locked bootloader. But I will find away to do it someday :laugh:

How do I relock the bootloader and go stock?

Hi XDA.
I was curious to find out is it possible to flash stock rom back on the device and relock the bootloader without bricking the device.
The EDL method seems like a pain..
The model is Raphaelin.
Flashed chinese 10.3.16.0, wiped system, flashed HAVOC, formatted data, wiped, booted. Everything works fine.
My questions are...
If and can i flash the EU rom and lock bootloader? Maybe through MiFlash.
Or
If and how can I flash the indian global rom and lock the bootloader after that?
Thanks guys!

Raphaelin means Indian ROM? If, you cant lock bootloader after flash different region ROM. If you lock bootloader after flash CN MI or RU type ROM, your device will boot lop means brick. You have to flash IN (india) official ROM to relock bootloader.
Download Indian Global Fastboot ROM and flash by XiaoMiFlash software.

You can only lock the bootloader with the ROM from the same region as the phone. In your case you can only lock the bootloader when flashing an official Indian fastboot ROM. If you try to lock the bootloader flashing any other ROM you will hard brick the phone. This can only be done when flashing the official fastboot ROM with the Mi Flash Tool.

Okk.. Thanks a lot!!!
Won't dare try anything stupid..

I have the Chinese version of k20pro and now I'm running the eu version of rom that is saying that my redmi is a 9t pro.
I also tried to lock the bootloader with this rom, but the phone got stuck on bootloop.
I thought that my phone is bricked, as no unlocked bootloader, there is no possibility to install the twrp and mi flash gave me an error. Luckily I put the phone in fastboot mode and run again the process of unlocking the bootloader and worked for me.
I would like to give it another try, but when I will have more time to read what other steps are needed and not to end up with a bricked device, especially that I enjoy this phone a lot.

You can not lock the bootloader again if you have any ROM that is not for the same region as your phone. With a Chinese phone, this means you can only lock the bootloader when installing Chinese MIUI.
You were lucky you had already unlocked the phone before and so had unlock permission on your Mi account. Many others have bought phones with the bootloader already unlocked, then done the same as you. Because they could not then unlock the bootloader, they have ended up with a hard bricked device, which needed flashing with an authorised service account.

How to Re-lock bootloader
Hi... I'm on stock rom Raphaelin v11. 0.4.0 global stable and my bootloader is unlocked. While using mantra RDservice app, it gives an error of rooted device. My device isn't rooted and every payment app runs fine. So I want to try locking bootloader to see if it works.

How to remove Alert Unlock Bootloader Screen V409N ?

im unlock boot loader , and them im relock phone to remove that alert , but i can't enter dl mode to stock , phone display red image

By red image you mean your phone failed the safty check or whatever check it is? You have to try flashing back original kdz then relock bootloader after that. Dont just be rooted with twrp and then decide to relock it.

my phone is v40 korea - no bootloader , i tried flash stock , then flash v35 bootloader to relock but after relock and reflash stock bootloader i can't enter dl mode , only red warning show

You flash the stock rom using LG UP then you use fastboot to relock your bootloader. If you have custom rom or recovery installed and then you relock then basically you ****ed up your phone. On every phone you always flash stock rom then relock after.

just download twrp flashable stock .zip for jasmine. Flash with recovery like any rom. Afterwards *enable* oem unlock and adb permissions... connect to pc via cable ...reboot to recovery ..if you still have twrp flash stock recovery ...
if you have stock recovery ..enter fastboot mode and use to lock bootloader
alternatively download a stock fastboot image amd flash it using Miflash
*just use a tutorial
* i suggested using first option because this option sometimes causes a soft brick if you use the wrong options

Question 12 Pro Bootloop - bricked?

Hi everyone,
I'm afraid that my 12 Pro commited suicide... :/
It's pretty new, only 2 weeks old now. I was using it with the latest Xiaomi.eu ROM a did not have any problems - tilll yesterday.
Out of nowhere it started lagging and crashed during normal use. After the reboot it seemed to be fine again.
But in the following hours it crashed several times and rebooted by itself. Even while sitting on the table with screen off.
Finally it ended in a bootloop.
What I've tried so far:
- reflash Xiaomi.eu ROM without wiping data
- reflash Xiaomi.eu ROM with data wipe
- reflash Global ROM with the Mi Flash Tool and "clean all"
- reflash Global ROM with the Mi Tool, "clean all" and Relock Bootloader
- factory reset in stock recovery
- start without inserted SIM card
What is working:
Fastboot
Recovery Mode (and ADB sideload using the Mi Tool option in recovery mode)
Unlocking the BL using the official Xiaomi Unlock tool
Occasionally it boots into system but crashes afer a short time, so I'm not eben able to complete the setup assistant.
Most of the time it just hangs at the boot screen (the one with the Mi Logo, "Powered by Android" text and open lock at the top).
Any suggestions how to bring it back to life?

It sounds like hardware problems.

Flash it back to the original rom that came with the phone.
Then check if the problem occurs again or not.
When not than it is a problem with the EU rom, and when it has the same problem it probably is an hardware issue.

Unlock bootloader again.
Flash with full Chineese ROM (i assume that yours is a Chinese edition) with the option bootloader relock selected.
Please note, you are good to flash Global ROM on the top of any Chinese ROM including xiaomi.eu ROM. But do not choose relocking because it will brick your phone permanently.
Avoid your step,
"- reflash Global ROM with the Mi Tool, "clean all" and Relock Bootloader"

Nope, I have the Global Edition.
So flashing the Chinese Rom and locking the BL is probably not the best idea
The device is at the service center at the moment, let's hope it won't take too long.

Worst out of worst, I can perform soldering and replace the nand chip of the device to recover it

I got my 12 Pro back und it's running fine so far.
Have had some random reboots in the past but they seem to be gone since the .18 update

Hi
That's exactly what I did. Is there any way to fix it?

What a situation?
You have locked the bootloader on a CN version with a Global rom or vice versa?

I opened the bootloader and uploaded the global rom to Chinese. I locked the bootloader. I got into a loop. Now I can't open the bootloader to load the new firmware
