First of all this process takes a long time, make sure you do it at a suitable time :)
Dont worry, the process of prepare account, mi unlock... its just one time.
If you bricked your phone before this tutorial just go to the bottom of the page, I can help you, so easy!

I made this tutorial from my experience.
I had a lot of bricks and mistakes and I want to share how to do it correctly and how to solve some errores.
I Hope I help you. :D

Prepare your account

- The first step is go to https://i.mi.com/

- Login with your account, or in the case you dont have one, register.

- FIND DEVICE needs to be ON, you should be able to see your phone here https://i.mi.com/mobile/find#/.
If you can see your phone, we can continue.


Observations:
MAKE SURE THE ACCOUNT YOU HAVE ON YOUR PHONE AND THE ACCOUNT YOU USE TO REGISTER IN THE NEXT STEP IS THE SAME.

Turn on Developer Settings and Mi Unlock Status

- Go to Settings, go to About Phone, Android Info and touch on Compilation Number until it appears "Now you are a developer".

- Go back and scroll down on settings to go to "advanced settings" or "aditional settings".

- If all is right, you need to see on the bottom a new option called "Developer Options", enter on it and look for "Mi Unlock Status".

26414


Press add account and device.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Now leave your phone appart and take your computer.​
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Mi Unlock

- Go to this page https://en.miui.com/unlock/download_en.html
- Click on Download and install Mi Unlock on your computer.
- Start MiFlash Unlock Tool
26416


LOGIN TO MI ACCOUNT WITH THE ACCOUNT YOU HAVE ON YOUR PHONE (FIRST STEP)

26417



Enter on Fastboot Mode and Connect to MiUnlock


- Take your phone and turn it off

- Press and hold volume down and lock buttons at the same time.

- Wait for this screen

26415


- Now connect your phone to your computer (It needs to be in Fastboot mode)

- When the program recognize the phone this is what you are going to see:

26418


- Click Unlock, you need to see an error like this, in my case it was 168h.
You need to wait the time is showing you the program. Dont worry, you can use your phone as always.

26419


At this moment you need to press and hold volume down and lock button and the phone is going to make a reboot. (This combination is so useful when a phone due an error it freezes itself)

Observations:
With a simply reboot you can use your phone as always, your aren't going to lose your data (Do a backup before)

Don't do a factory reset, try to have always internet connection during this time.

After the time

After the time the program showed you, simply go back to fastboot, reopen Mi Unlock and try again. This time this window will come out.

(This step will erase all the contents of your phone, make sure you make a backup before.)


26420


AFTER SUCCESFULLY UNLOCK
- Now reboot the phone (Now you dont have nothing on your phone, It's like we turn on a phone for the first time so it will take a while)
- You're going to need WIFI signal. You are going to see a message of Xiaomi with 2 opcions "WI-FI settings" and "Activate this device"
- Press on WI-FI Settings, put your WIFI password and go back
- Select Activate this device and just put your account password (This is the reason of how important is the account step)

-Go to Developer Setting
If you don't see it, follow one of the first steps on the top of the post.

Go to Mi Unlock Status to make sure it place that your phone is unlocked.

26421


After comprobe that, turn on USB Debugging and OEM Unlock.
In developer settings too.

26422



NOW LETS START WITH THE INSTALLATION.

Install TWRP
26424


Download TWRP installer. Includes TWRP version (3.3.1-2):

http://www.mediafire.com/file/xqf8k1c80qzn3d6/twrp-3.3.1-2-davinci-fix.zip/file

Dowload TWRP installer. Includes Russian TWRP. (I prefer this one)
https://www.mediafire.com/file/mvkklin37lfgnak/Install_TWRP.rar/file

The Installer is universal, It means that if you want to install other TWRP version you just need to replace TWRP.IMG for the other TWRP that needs to have the same file name.

- Enter on your phone on Fastboot mode

- Run Flash_TWRP.bat and just follow the indications, press a key when the program tells you.

- Press and hold Volume down + lock button to reboot

- During the reboot press and hold Volume Up + Lock button to enter in TWRP menu.

- Go to Backup, select all the options and press continue, that backup its going to be located on TWRP - Mi9t - and the folder.
Save that folder on your computer.
You can do it from TWRP, just connect or reconnect the cable to your computer to access to your internal storage, in case this doesn't work go to mount option in TWRP, select all options and click on the right button.

Observations:
If the screen turns black instantly, try to press lock button and slide as its indicated.

Its going to request you a password, It's the same of your phone (your lockscreen password)

Download and install Xiaomi EU ROM

AFTER THE INSTALLATION OF THIS VERSION IT'S SO IMPORTANT TO CONTINUE AND FINISH THE INITIAL CONFIGURATION AND LOGIN IN YOUR GOOGLE ACCOUNT.

Some betas have problems with the initial configuration and you could have a black screen with no solution on the Google Login so you can't continue configuring. Make sure to do the initial configuration it in this version.

Download this (ROM 10.3.15 Stable)
https://sourceforge.net/projects/xiaomi-eu-multilang-miui-roms/files/xiaomi.eu/MIUI-STABLE-RELEASES/MIUIv10/xiaomi.eu_multi_HMK20MI9T_V10.3.15.0.PFJCNXM_v10-9.zip/download

To install
- Download the rom
- Connect your phone to the computer
- Move the rom (.zip) to your phone internal storage
- Enter in TWRP Mode

In TWRP
- Go to Install,
- Search for the .zip (xiaomi.eu_multi_HMK20MI9T_V10.3.15.0.PFJCNXM_v10-9.zip),
- Click on it and slide to confirm installation.
- Wait

Important Observations:

After the process you have two options "Wipe Dalvik Cache" or "Reboot", in the case you want to press both of them, first do it with the "Wipe Dalvik Cache" (This dont delete any data of your phone) after that press reboot.


BE PATIENT! Xiaomi is so sloooooooow to start new roms and updates so if you see this with the 3 dots moving, dont worry 99,9% you did it well.
Other indicator that you did it well is that on the first or second minute you are gonna notice that the brightness of the screen goes down, dont worry at this point it may take 5 minutes more maybe.

26425



AFTER INSTALL 10.3.15 STABLE

VERY IMPORTANT TO INSTALL ROMS IN THIS ORDER AND WITHOUT WIPES TO AVOID BRICK.
DON'T WIPE SYSTEM, DATA,CACHE... JUST INSTALL, WAIT FOR A SUCCESSFULLY REBOOT AND REPEAT.

(TWRP -> Install 10.3.15 -> Successfully reboot -> TWRP -> Install 9.8.1 -> Successfully reboot -> TWRP...)

THE SAME INSTALLATION STEPS OF THE LAST FILE (10.3.15)

Download Beta 9.8.1

Download Beta 9.8.8

Download Beta 9.8.15

At this point, installing 9.9.26, your TWRP version is going to change to chinese, don't worry its completely funcional.
You can use it to install 9.10.17. Just install 9.9.26 and use the new TWRP version to flash (Just install, no wipe) the
new 9.10.17 version.

Download Beta 9.9.26

Download Beta 9.10.17

HOW TO UNBRICK YOUR PHONE

Dowload MiFlash

https://www.mediafire.com/file/kgj7o1ssbouo22h/MiFlash20181115.rar/file

Download 10.3.6.0 Global Rom (.tgz)
https://www.mediafire.com/file/w9oqcdr2obvpqlm/davinci_global_images_V10.3.6.0.PFJMIXM_20190603.0000.00_9.0_global_a0c4a98edb.tgz/file

STEPS
- Unzip the files
- Enter in MiFlash folder and search for "xiaoMiFlash.exe" and open it.
- Enter on your phone on fastboot mode
- Now on XiaoMiFlash program, press select, and select the folder you obtained from .tgz file.
- Click on Flash
- Wait (In my case 334 - 385 seconds)
- All ready! When you start the most common is that you get an update to 10.3.11, do it and follow my tutorial from install TWRP.

Observations:
Don't worry If you don't see your phone on the program at the moment to click flash. Just open the program, select the folder extracted from .tgz and click flash, you will see that your phone its going to appear with a progress bar.

I hope I helped you! Enjoy it, It takes a lot of effort and time :D
Don't forget to share and comment.

Hi!
The steps after installing the 10.3.15 are a little bit unclear for me:
First, after installing the Beta 9.8.1... I need to reboot to system or immediately go to install the 9.8.8 and the others?

First you need to install 10.3.15, after install you just need to install the other versions in order, without any type of wipe (just dirty flash) , we are installing updates. (TWRP -> Install 10.3.15 -> Successfully reboot -> TWRP -> Install 9.8.1 -> Successfully reboot -> TWRP...)

thank you.
Some people say that for example you can Install 9.8.15 after 10.3.15, in my experience I prefer to Install the updates from the beggining.
If you are on 10.3.15 you need to install 9.8.1 - 9.8.8 - 9.8.15 - 9.9.26

once you installed 10.3.15 and then 9.8.1, you can install directly 9.9.26?
i mean, no need to wipes data before/after install 10.3.15?

You need to install 10.3.15 - 9.8.1 - 9.8.8 - 9.8.15 - 9.9.26 in this order. In my case, I did it without wipes so I not sure of recommend you to do it.

Hi!
To check if I could solve some errors besides to see if I had made a mistake in some step of the tutorial or if I had put a file wrong, I have made a format data to start over, MIUI 11 had quite a few errors but I have realized that reinstalling all have been solved.
In my case, OTA works again, Gmail and mail apps are working so fine, Movistar Next works again too...

All is working fine and smooth for me this time. If you're so fan of dual apps I will recommend you to wait for a Stable release, but if you don't need it follow my post and update to miui 11.
It's so smooth and works really fine, I have very good battery too, better than Miui 10.

Thanks for this post.
Tried going directly to 26 as advised by the official release post, I just ended up in a logo boot loop.
Tried this method and it worked :)
Battery drain is a little worrying though compared to what I had on stock, it seems to be going down faster than usual.

Thanks to you for trust on me! :D
In my case the battery is better than stock but maybe is because the other day I install MIUI 11 from 0, starting from official 10.3.12.
I'm not sure because before do this I had some errors, now they are all solved. Maybe I should erase the DATA partition with each installation.
I have preferred not to investigate further at the moment.

I will continue investigating doubts and looking for improvements in the process. :)

Hi! So happy to hear that my tutorial helped you! :)
Don't worry it's normal, Xiaomi.eu roms are based on China Rom, K20 and Mi9t are the same phone.
The companies are always trying to give a easy name for every place, so in Europe is Mi9T and on China is K20.
