Back to official EU rom? - Redmi K20 / Xiaomi Mi 9T Guides, News, & Discussio

Hello. I came here for help. As i no longer focusing for phone rooting, i'm not able to switch back to stock rom for Mi 9T. Currently i have old MIUI 10.5 by xiaomi.eu 9.8.1 . I want to switch back to stock, most up to date version of ROM for this phone. I would like to ask how to do it. I'm pretty sure i need to update my firmware before flashing latest stock rom but i don't know which firmware. Can somebody post here up to date manual with steps how to do it? I also know about some MIUI program for Windows that can help but i saw many times it just hard bricked the device. I would appreciate some experienced user to tell me what to do.
I'm really sorry to ask here for this (newbie help) but as i said, i'm out of it for like 2 years now.
PS: It would be nice to don't have anti-rollback protection (just in case)

This guide should help you. This is for locked bootloaders but the main procedure is almost the same:
[GUIDE] Flash Official Xiaomi Firmwares with a locked bootloader GLOBAL/CN
Hi, in this guide I will show you how to flash different official firmware (Global and CN) without having to unlock the bootloader. DISCLAIMER: Just to be sure, I am not responsible for any bricks or damage to your smartphone. Use this guide at...

As your bootloader isn't locked anymore the whole thing is less risky.

[Q] Noob question: install custom rom / revert to stock

Hi all,
I'm quite new to the sony and android scene. My iphone 3GS broke down a while ago (actually I dropped it ) and I had it replaced by a Mini Pro.
I'm on the stock 2.3.4 rom and would like to test the miui version on this forum.
So, my question is simple: I need to unlock the bootloader to install a custom rom.
Can I revert to a stock rom (or upgrade to the new upcoming ics stock version) without loosing DRM etc?
And what's the procedure to do so?
you will have to follow this guide http://forum.xda-developers.com/showthread.php?t=1285285 that is the only way to unlock it without losing drm and the ability to officially update.
Looks quite scary stuff to me. Coming from a jailbroken iphone, it looks like this is a bit trickier. Thank you for the reply though
Another small question then: can I still upgrade to a stock rom version if I have unlocked the bootloader? (via an unofficial way that is)
yes you can, but if you unlock your bootloader the official way you are not going to be able to update using sony software.
and yeah it looks scary but it is easier than it looks.
Great, thanks for the info. I'll search around the forum for the unofficial unlock mechanisms and will have a try with them!

Some guidance redmi note 3 pro before i commit to buy

Hi Folks,
Been reading alot of different threads and searching the net. I see some of the sellers on e bay have roms with google play store and multi languages pre installled. From what i gather these seem to be a custom rom and not the global rom. (which has me thinking is the bootloader unlocked on these ones?)
Are there any disadvantages to buying these? will the rom get OTA updates( probably not) ? will they contain more bloatware than the stock original rom?
So should I buy stock rom? Then upgrade to the Global rom for the english and to get rid of any chinese stuff on the phone?
If i want to install custom roms, then i gather the best way is to request via the mi link to have bootloader unlocked and flash to the developer ROM.
i have read a few different ways, users maybe bricking phones. So want to ensure I do things right from the start.
Any advice is most welcome.

1.bootloader is not unlocked
2.all phones,which don't come from mi.com have custom roms installed and you will not receive OTA upadtes in future,but you can install original MIUI Global Rom.It don't care if they contain bloatware,you will flash new rom
3.you don't need to buy sotware,it is free from miui forum
4.i don't recommend you to unlock bootloader and to install custom roms;too many people around us cry after this action.Stay with original rom and you will don't have problems
P.S:i suggest you to buy from trustworthy reseller and not from Ebay or untrusted sources,easy you can receive a fake device.
Thanks for the tips, one final question as a lot of the flashing process seems to be all over the place or conflicting information.
If I had a stock version rom and a custom rom , do both require for the boot loader to be unlocked to flash to the global rom? Basically I just want the global rom, that will get updates and just install google services . It's a phone for the wife. Don't want a lot of bother. So in just trying to force a reliable seller and gather whether I need to request to get the boot loader unlocked or not.
There is a way to flash roms with locked bootloader. Just having vendor rom doesn't necessarily mean the bootloader is unlocked.
Vendor ROMs or unofficial MIUI ROM might have malware/bloatware pre-installed. I myself prefer official ROM unless the customized ROM is from well recognized developer.
If you'd like to have global rom, then you should buy the redmi note 3 with qualcomm cpu, aka redmi note 3 pro.

You can install Global Rom even the bootloader is locked(mine is locked);global rom have google services preinstalled,you don't need to install nothing related to Google apps.The phone is very good and speedy and nice.One more timeON'T UNLOCK BOOTLOADER.Think a litlle and ask your self:Why Xioami had to invest more money in extra security?

How to root after official unlock of bootloader (SNAP650).

Hi guys,
I'm from India, and I have the Redmi Note 3 Snapdragon 650 variant. I have successfully unlocked my bootloader via the official process using MiFlashUnlock tool. I am on MIUI Global Stable 7.3.2.0.
Now that I have unlocked my bootloader, I want to root my device, and I had a few questions.
1. What's the method of rooting. I read that I need to install TWRP. A link to the latest updated guide would be much appreciated.
2. After rooting, will I be able to get proper regular updates? If yes, will it unroot my device after the update? If yes, then what do I do?
All in all, I am looking to root my RN3 and keep getting proper OTA updates and still retain my root access.
Any help in this regards would be highly appreciated.
Thanx a lot in advance. Desperately waiting for a reply
Edit: The main reason for creating this thread is coz there is a lot of confusion right now as there are various methods to root RN3 and then there is a different way to do it if you've unlocked your bootloader UNOFFICIALLY.
With all this chaos, I just wanna know what's the correct procedure for me
+1 good question, i also want to know, see complete guide for ppl who unlocked officially ONLY.
You can receive OTA's, and you can download them, but you can't install them.
Also you should flash the official TWRP if you officially unlocked the bootloader. Be sure to download the universal boot image patches from the safe TWRP thread and also you can root from TWRP. When you open TWRP, it'll ask you if oyu want to root.
Use this recovery : http://en.miui.com/thread-282773-1-1.html , then you dont need flash modified boot.img everytime you flash miui roms.
After you flash OTA updates , your root access will be gone, so you need root again from twrp.

Exactly i m stuck here( kind of), cause this installation guide start like this.
" Reboot to twrp.
........
...........etc,etc.
Now it doesn't say how to flash twrp.
That alka.... author thinks/ want us to on twrp preinstalled. Help if possible to officially unlocked ppl
You have to flash recovery via fast boot
Sent from my Redmi Note 3 using XDA-Developers mobile app
Thanx a lot for the replies guys.
Well, I wanna learn everything that's related to Redmi Note 3 flashing, rooting, etc.
Like, to install TWRP, why do we need to flash a modified boot.img file? Is this also required if we have UNLOCKED OFFICIALLY?
Also, @justinxfan @ddarshan - why won't it install the OTA? Nonetheless, after downloading that OTA zip, we can install the OTA zip using TWRP without losing any data, right? And then, of course, as you said, we can again gain root access via TWRP right?
By the way, for now, I am not interested in any roms. Am very happy with the current MIUI Global Stable ROM. Just want root access but also wanna learn
It will be awesome if someone can list the differences and what to do after official and unofficial unlocking methods. Few more questions, does flashing any miui rom via twrp after official method will relock the bootloader or it can be done only by edl method? Also, flashing by edl method will remove twrp right?
Seriously guys, please help us out
if u unlock bootloader unofficially ,it will void your warranty but official unlock will not.

+1 for cofface's TWRP. I'm on officially unlocked and rooting works by flashing the latest SuperSU.zip through TWRP. I am not sure if Global Stable even allows root though, since I'm on Global Dev. I can also recommend going to xiaomi.eu ROM when you are unlocked. It's rootable and based on the latest version of MIUI without the chinese bloat. A good filler until a stable version of CM13 is released.

Original firmware backup/download

I have an Mi 10 with QJBEUVF firmware. (brand vodafone)
Where can I download this version?
Can I boot with TWRP recovery and make a full backup of the entire phone and then restore it and return to stock?
My goal is to test other ROMs but then return to stock.
Thank you.

You have operator based version of MIUI, not released. You can unlock bootloader, then flash twrp. You can use EU rom for better experience. You can lock bootloader with Global or EEA rom.
Thanks, but I knew that.
I explain to you.
I've always had Nexus and Pixel, I just don't like the Miui.
I wanted to test Pixel experience rom, and if it doesn't convince me return stock and return the phone.
I can't return it with another firmware ...

Search for the firmware on the internet and download it so it can be flashed if needed.
i have same issue here, same firmware code, so i guess the phone of the OP is a Mi 10. i cannot find to download this firmware, as like sceryavuz said, it's not relased since it's a vodafone fw.
the process to swap it's quite simple i saw, only using miflasher, and selecting clean all and lock(for locking bootloader again) but i simply want to make a full backup of this one, in case something goes wrong. (i only have this phone, and cannot risk to lose bank support, gpay or the phone at all, for work reasons).
thank you in advance for the great support here

Question Relocking bootloader

Hi
I bought a second hand K50 gaming but working with poco f4 gt rom. If I proceeded to relock the bootloader, will that cause a brick doing so? And may I know why in simple way?

Are you 100% sure about it? I am aware that it has been like that for a good while now, the thing is that i just installed the lastest MIUI CN via fastboot. I have a F4 GT and its now showing device model as 21121210C which is for CN. The device model of F4 GT is 21121210G and i believe that would prevent from properly locking it. I think MIUI 13 would always show 21121210G no matter the rom you flashed but they may have changed it, perhaps due to too many RMA's.
Sadly im not gonna risk it to lock it since i cant really afford the trouble it could cause, if we ever get a leaked qfil programmer ill give it a go.
