If it is still with kitkat based rom, first you have to get partitions merged together, install new China developer rom with MiFlash. (There is other method, but it has many more steps.)

Download Mi PC Suite, MiFlash and china dev rom, install PC Suite and MiFlash. Restart phone in fastboot mode, hold volume down and power button at the same time until fastboot picture. Unpack dev rom, install it with MiFlash and boot to MIUI.

Download latest xiaomi.eu beta rom to phones internal memory. Restart phone in fastboot mode.

https://dl.twrp.me/cancro/twrp-3.0.2-0-cancro.img.html

Download latest TWRP Recovery and unpack twrp-3.0.2-0-cancro.img to "C:\Program Files (x86)\Xiaomi\MiPhone\Google\Android" (or where you installed MiFlash or to other fastboot location).

cd "C:\Program Files (x86)\Xiaomi\MiPhone\Google\Android"
fastboot devices
fastboot flash recovery twrp-3.0.2-0-cancro.img
fastboot boot twrp-3.0.2-0-cancro.img

Install twrp and boot it (in fastboot mode). Devices command to check phone is in fastboot mode and driver is working, it should return serial number. Then install recovery and last line to boot directly in TWRP Recovery, it also disables automatic stock recovery install.

Then from TWRP Recovery wipe cache+dalvik+user data, install xiaomi.eu rom and reboot system.

Wow.... now that's quite a detailled description!

One question, how do you merge The partitions together?
And that New China developer rom is that only in Chinese language ?

Tx aggain!

MiFlash install also writes new partition table. It has chinese and english.

hi,

i now have got the Phone installed with the latest chinese dev.rom: MIUI 8 6.7.14 Beta.
Next step is to install TWRP and than flash the latest EU dev rom.

I ám stuck on installing TWRP.
I have tried it for almost 5 hrs and it just wont work....

On the Phone after installing the chinese rom i have done a wipe on the dalvik,system,user data and even the sd card.
Downloaded the latest version of TWRP,cancro,on the Phone (zip File) and tried to install it via the updater app.
it gives me the error:install.update.zip failed
error applying update.

I have also tried an older version of TWRP but it gives me the same error.

I have also got the same files on my laptop,booted the Phone into Fastboot,had the file from ADB imnstalled on the C disc and tried to open the ADB Via CMD and than is doesn't recognize the command fastboot.

can somebody please help me?

im out of options now and stuck....

 

[Michel M]

i would prefer an option to install via updater app as Im not experienced to work with the fastboot method at all...

 

[Michel M]

Okey....it is solved...ik roled back to Version 6.2.25 and that came out with twrp.
Booted into twrp and installed The latest eu rom.
