Official Miui 9 stable after bootloader unlock - Xiaomi Redmi 4X Questions & Answers

Hi . . . I am new in redmi 4 but i know all about roms flashing and unlocking bootloader because i am tried a lot of roms on my previous mobile . . I want to know is possible to flash official miui fastboot update after unlocking bootloader on redmi 4 ?? And after flashed fastboot update is bootloader will be locked again ??

Yeah, you can flash official miui with fastboot. MI flash app have an option to re-lock the bootloader or simply flash the rom without touch anything. You can see this option at the bottom right of the program
Also can happen that you flash the rom and accidentally lock the bootloader, because this option is marked by default. In this case you only need to unlock the bootloader again with Xiaomi's program, don't need to wait 72 hours. This already happened to me.

With locked bootloader I prefers xiaomitool for upgrading or downgrading any miui rom.
Use xiaomitool it is safest tool

Tnx for the replys i got it

Just want to relock global version 8.2

My frustration level is super high with this brand new Mi Mix I bought from a US reseller that came unlocked with the official latest global rom version. Before I decide to return it, can anyone please tell me a simple way to relock the bootloader so I can download Netflix and use this device like normal? I can't even get the Mi PC suite to recognize its connected. Very annoying!
do you try mi flash? there are options clean install dirty and clean relock install
No, do I need too flash the rom again with the tool to relock or is there an option to just lock the bootloader only? Will I still get Global Rom updates after relocking? Am I able to unlock in the future since it's already been unlocked once by the reseller? Thanks for your earlier response! I'm just not that good with all the modification stuff.
No You cant relock without clean install anda yes You will recieve otas
And for The re unlock You have to need a code if your seller unlock it then You have to get xiaomi unlock permission again once You recieve The code with your acc You can lock relock unlock anytime You want

Thanks! So can I just do a clean reinstall directly from the phone and will it automatically lock for me? I apologize - I'm not really technical with this stuff. I'm on the latest Global Rom that's on the official site. I don't want to change my rom or root in any manner. I just want keep it the way it is and simply lock the bootloader. I have read some other guides about flashing and downloading a whole bunch of drivers and changing settings on my PC to get it to work. Isn't there any easier way of doing this? I want it to work like if I just bought it at a store and allow me to set it up like have with my S8+.
Then install mı flash and fasboot rom of your choise global stable or global beta then close The phone and open pressing w power button and wolume down button at The same time once You ses The tinker bunny (fasboot mode pic) connect your phone with a cable and install with mı flash of your choise of rom and ext its very easy en.miui.com download section You can fallow The steps there its tooooo easy You can spor

Hi Egentreri,
I am surprised to read by your reply; I thought the bootloader could be relocked using a fastboot command. I have bought a Mi6 a few days ago and it came with an EU rom. I decided to flash the Global Rom using the regular update tool from the rom itself, but unfortunately TWRP was installed, something I hadn't checked... and I bricked the phone. I managed to reflash the stock recovery (in chinese) in fastboot and I the phone some how booted again and I could reflash the rom from the update tool and this seems to have flashed a new stock recovery as it is now in english?
My bootloader is still unlocked, but I guess I could use the fastboot command to relock the phone as I now have a stock recovery along with a stock Global Rom? What do you think?
Thanks,
Alex

In my non expert opinion and little experience flashing som custom roms and then going back to official (beta and stable), and back again to custom with twrp recovery and all... Sure and easiest method for going to any of the official roms and having the bootloader relocked is to flash chosen rom with fastboot update: for the Mix: http://en.miui.com/a-234.html
That way, which I understand is what @gman901 did, with the same package you get back to locked bootloader, stock recovery, etc.
I got my Mix unlocked also, which I didn't mind as I quickly rooted and went to try some fantastic custom roms. But the first weeks, when going back and forth and trying this and that, at some point I wanted to go back to vanilla official global stable, and from there to global developer. To do the first step from custom rom only fastboot update worked.
Hope this helps!

Bricked Mi8

Hello,
I have a mi8 bought at GeekBuying. It had a open bootloader and a "Global Rom". I tried to update to the eu Rom. Now I have a bootloader locked and the phone only goes into safe mode and fastboot mode. I tried to go back to the official Chinese firmware which did not work as the phone is bootlocked. Also can not do the unlock process using the Xiaomi homepage as I can not access the dev settings...
Any suggestions? Send back to China?
How is it possible to lock the bootloader? Did u use fastboot lock bootloader? Or using Mi flash?
Normal u can flash Xiaomi.eu rom without a problem with a unlocked bootloader it isn't possible to lock a bootloader by flash the eu rom in Twrp.
By the way, I never and I mean never seen so much ppl with bricked phones.

I used fastboot flash. With the official unzipped Rom from the official site. There was also no option to lock or unlock. Old rom had unlocked written on the bootscreen, now shows nothing about it anymore?
Maybe has to to do with a modified firmware by the shop I bought? I myself did not unlock the phone... Came like this.
I bought it also from Geekbuying. I told them that I want to sent it back, cause the box was not a new one, the box was not sealed and the boot loader was unlocked. I have also a bricked phone and I can't use Mi unlock since my account is not bound to this phone.

It´s posible install xiaomi.eu rom with bootloader locked ?

Id like to know if i can install rom in a redmi 4x with bootloader locked (not official rom)
Actually i have Global last developer Miui10
Thanks

Phone will not allow you flash unofficial img when bootloader is locked. I dont think it will let you lock after flashing rom with unlocked bootloader. At least i cant manage to lock bootloader after debloating miui stable.
With locked bootloader only official update can be installed through the updater app and that to stable ROM.
You can relock bootloader again regardless if you use official MIUI beta or stable ROM.
You'll have to unlock bootloader in order to flash any other ROM let it be any ROM.

Questions about the anti rollback

Hello
I have the Mi9 T PRO running MIUI Global 10.3.1.0 stable (PFKEUXM).
I don't intent, and there is no reason, to mess with the different MIUI versions.
I am interested to root the phone or try a custom ROM.
My questions are :
1)If I unlock the bootloader only for root and then relock it, my phone will be bricked?
2)If I try a custom ROM and then relock the bootloader the phone will be bricked?
3)In a previous post is mentioned that if you downgrade from beta Q to stable P the phone will not be bricked. What about the anti roll protection?

Its EEA (EU) ROM
MIUI Global ROM PFKMIXM
You can re lock your bootloader wothout problem but only if your original rom. If you are on EU or EEA you can flash and lock BL.
The problem is only if you flash different rom and re lock bootloader

This applies for AOSP ROMs too, right?
AOSP+relock=brick ?
And something else.
TWRP+ROOT+stock MIUI, can I relock bootloader?

As far as I'm aware relocking the bootloader doesn't work using fastboot commands. I can't remember if it will brick the device if you try, so best not to try.
When using the Mi Flash Tool you can only lock the bootloader when flashing a fastboot ROM, so this will restore the phone to factory and you'll lose any custom ROM installed and any recovery and root installed.
Really it's only safe to lock the phone when staying on the original ROM of the phone.

replace russian rom official with global rom official

i bought a mi 9 lite and it came with the russian rom.
I wanted to unlock the bootloader and install the official globlal ROM with mi flash. can i lock the bootloader again with me flash when i install an official global rom?
or
is there a guide to install a global rom without unlocking the bootloader? and without using tools?
You need to first unlock your bootloader in order to fastboot flash the global rom (using MiFlash). After that in the MiFlash tool there is an option to "Flash all and lock" which will lock your bootloader again. Unfortunately there is not a way of doing it to my knowledge without unlocking your bootloader.
Here's the official guide here: https://c.mi.com/oc/miuidownload/detail?guide=2
Never, ever re-lock your bootloader as this will result in a hard brick that can only be resolved with EDL/authorized account!

Not to my knowledge. I have done it before with my device. Sure if you want to use custom roms/recoveries you will need to unlock your bootloader again which you can do if you are using an authorised account. However, if you are really worried about this happening, you might as well just keep your bootloader unlocked.

Before i could unlock my device, i was able to flash a global rom with a non official tool which name i can't remember.
Global rom was the only one i was able to flash. So yes it's possible.
ok
On which ROM and Device you CAN and CAN'T Lock Bootloader!
