Hi!

This process takes a long time, make sure you do it at a suitable time :)

Bricked Phone?
The instructions to solve it are at the end of the post.

Telegram: @Danxell

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1.Prepare your account

Computer Step

- The first step is enter here https://i.mi.com/

- Login with your Mi Account with the same account you are logged in to your phone
(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 use on your phone and the account you use to login is the same

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
2.Developer Settings and Mi Unlock Status

Phone Step


- Enter on Settings About Phone → Android Info and touch repeatedly on Compilation Number until it appears "Now you are a developer".

- Go back to Settings and look for "Advanced settings" or "Aditional settings".

- Enter on "Developer Options" → "Mi Unlock Status".

- Press Add Account and Device and continue to next step.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
3.Mi Unlock

Computer Step

- Enter this page: https://en.miui.com/unlock/download_en.html

- Click Download and install Mi Unlock

- Start MiFlash Unlock Tool

26416


- Login to Mi Account.

26417


Observations:
Do not close the program, keep it open
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
4.Fastboot Mode and MiUnlock connection

Computer / Phone Step.

- Make a backup of your files, messages, apps...

- Turn off your phone

- Press and hold Volume down and Lock Button at the same time.

- Wait for this screen

26415


- Connect your phone to your computer (in Fastboot mode)

- When the program recognize your 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 168 hours.

26419


To continue with the process you need to wait the time is showing you the program.

Press and hold Volume down and Lock button and the phone is going to make a reboot.
With this simply reboot you can use your phone as always.

Volume down + Lock button
This combination is so useful to reboot in situations when your phone gets freezed or you can't select a turn off option

Observations:
Use your phone as always, don't do a wipe or factory reset, try to have always internet connection during the 168 hours.


---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
5.After "error" time

Computer / Phone Step

- Take your phone and enter on fastboot mode.

- Connect your phone to the computer.

- Open Mi Unlock and try again.

-This time this window will come out.
This step will erase all the contents of your phone

26420


---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
6.AFTER SUCCESFULLY UNLOCK

I consider a succesfully reboot when you can use your phone as always, It means for example enter your SIM code, use apps, call...

Phone Step.

- 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 need WIFI signal. You are going to see a message from Xiaomi with 2 options "WI-FI settings" and "Activate this device"

- Press on WI-FI Settings, put your WIFI password and go back

- Select Activate this device and put your account password

- Enter in Developer Setting → Mi Unlock Status to make sure that your phone status is unlocked.
If you don't see Developer Settings, go back to 2nd step.

26421


- Turn on USB Debugging and OEM Unlock. (In developer options too)


26422


---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
NOW LETS START WITH THE INSTALLATION.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
7.Install TWRP

Computer / Phone Step

26424


- Download TWRP:

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.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
- Put your phone on Fastboot mode

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

- Press and hold Volume Down and Lock button to reboot

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

- Go to Backup, select all the options and press continue
(Backup its going to be located on TWRP - Mi9t - and the folder).
Save that folder on your computer.

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)

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.


---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
8.Download and install Xiaomi EU ROM

Computer / Phone Step

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 in this version.

Download this ROM (Xiaomi.eu 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 ROM (.zip) (xiaomi.eu_multi_HMK20MI9T_V10.3.15.0.PFJCNXM_v10-9.zip),
- Select 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



9.AFTER INSTALL 10.3.15 STABLE
If you want to install directly the last version (20.1.16 Beta) continue to last part of the post!


Phone Step

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 installation steps are the same 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 / 9.10.24 / 9.11.7. Just install 9.9.26 and use the new TWRP version to flash (Just install, no wipe) the
new 9.10.17 / 9.10.24 / 9.11.7 version.

Maybe when you try to enter in TWRP your phone reboots and does not enter, just wait for the second reboot and press Volume down and Lock button.

Download Beta 9.9.26

Download Beta 9.10.17

Download Beta 9.10.24

In my case I didn't had any problem (Maybe because I used the first version) but Xiaomi EU did a reupload with a 2nd version of 9.11.7 (don't know why) and some people are having problems installing it with the TWRP of 9.10.24 (That is the same of 9.9.26, 9.10.17 and 9.11.7).
Xioami Eu suggest this TWRP:

Install It before continue installing.

Download It, enter on TWRP, Install and touch on Install Zip to change to Install image, search the new TWRP version (.IMG) and touch It, Select recovery and Install, press reboot system and download the next versions: (Install as always)

Download Beta 9.11.7

Download Beta 9.11.14

Download Beta 9.11.21

Download Beta 9.11.28

Download Beta 9.5.12

Download Beta 9.12.12

Download Beta 9.12.19

Download Beta 9.12.26

Download Beta 20.1.2

Download Beta 20.1.9

Beta 9.1.16 can be installed directly without install the other roms, remember that this tutorial is made from the view of a person who installed the first rom from the beginning, surely many of these roms can be installed directly only by having the indicated TWRP, format data and flashing.

I have done this tutorial from the beginning following my steps and therefore I know that with it you will not have any problem, but it is tedious to download and install all roms 1 by 1, so I tried to do a format data and flash this Beta 20.1.16 and I had no problem.

So the steps would be to have the TWRP 3.3.1-Davinci, Do a format the data, restart the device again in TWRP, connect to your computer and transfer the rom to your internal storage and flash. Then as always wait, calm that it usually takes a long time, up this page on installing the stable version I explain some details of how to know if the flash went well.


Download Beta 20.1.16

Unbrick Phone:

Download 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

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...)

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.
