Just asking to be sure. I'm on rooted global 10.3.11 with fixed russian 3.3.1-2 TWRP at the moment. If I want to install stable xiaomi.eu 10.3.15, do I need to wipe or format anything before/after installation or can I just dirty flash it over my current global ROM?
If I followed the installation guide correctly it doesn't say you have to wipe anything, correct?
Thanks in advance

From Official ROM, it's required to "Format Data" before flashing EU ROM or phone will always reboot to Fastboot (bricked state).
EDIT: My steps to install:
1) Boot to TWRP
2) Wipe -> Format Data (type "yes" to confirm)
3) Back to main TWRP menu -> Reboot -> Recovery
4) Copy EU ROM zip file in internal storage via USB
5) Install -> Select EU ROM zip, flash it and wipe Dalvik/Cache before reboot

Its necessary to install beta versions after the installation of xiaomi.eu 10.3.15
Sorry if i dont make myself clear enough google keyboard betrayed me. I was just asking since the new stable version is the 11.0.3. Can i install this one directly instead of the 10.3.15 and the beta one

Hi, i'm on 11.0.2 EEA stock ROM. I want to install weekly xiaomi.eu ROM after unlocking bootloader. Do I need to install all versions from the 1st post of this thread?

Hey, I just updated directly from MIUI 10.3.15 (Android 9) to MIUI 11.1 (9.11.21 beta) (Android 10) with no problems:

unlock bootloader (Follow the tutorial, including TWRP installing)
install twrp ( rus that's in this thread) via fastboot (WITH .BAT FILE) and REBOOT TO TWRP (critical step) by holding power butrón and +volume, if not the stock rom will replace the stock recovery and you'll have to flash it again
format data and then reboot again to recovery
copy rom (i'm using weekly 9.11.21)
install
wipe cache

Hi, I've seen many people saying different ways to install this so I'm still kinda confused..
I'm on latest Global Stable MIUI 11.0.1 and I want to install the latest weekly EU ROM.

- flash LRteam 3.3.1-1109 TWRP
- reboot to recovery
- format data > type yes
- reboot to recovery
- install latest weekly EU
- wipe dalvik/cache
- reboot system

Is this correct? Going from Global Stable MIUI 11.0.1 to latest weekly.

miflash? MIFLASH?
You are using Miflash?
That's impossible .
Please install EU weekly with TWRP.

I've started using .EU yesterday for the first time and the difference from Global Stable is brutal. Android 10, bunch of new features, improved smoothness.. so much better! Thanks for all the hard work devs!

In case there's still someone wondering how to install latest weekly, that's how I did it:

Coming from latest Global Stable MIUI 11:

- flash LRteam 3.3.1-1109 TWRP
- reboot to recovery
- format data > type yes
- reboot to recovery
- copy ROM from PC to phone
- install latest weekly EU
- wipe dalvik/cache
- reboot system

I can confirm the same... coming as well from Miui 11 stable. It's so much better, incredible! So many thanks for all the efforts! :)

Is this safe to update? Found it under Settings > Privacy > Security Stats > Google Play System Update

Latest weekly, no root.
