Cant return to MIUI from LineageOS

Wipe everything
Install global developer zip file
When reboot, twrp says no OS installed
Help pls

if the recovery method of flashing the full rom fails, then you have no other recourse except to flash via fastboot method.
take note of this "Please wipe all data in Recovery mode if you want to update to a discontinuous ROM version, or downgrade to an older ROM version using MIUI full ROM pack. If you upgrade from MIUI Stable ROM based on Android M to MIUI Developer ROM based on Android N, please flash it via Fastboot update. Recovery update might cause upgrade failure."

Did you just tried rebooting to system after flashing? I also got that error "no OS installed" in TWRP so many times, but rebooting to system with no problems at all.

Unmounted system before flashing ROM .

in my opinion why just not use rom from xioami.eu because you have custom recovery .

The reason is, that you can't flash OFFICIAL Chinese (Developer/Stadle) Rom with cusom recovery (TWRP). But you can flash anything esle. Like Lineage OS. If you want to use MIUI Rom, you have to flast a Xiaomi.eu ( developer or stable) rom. NOT OFFICIIAL CHINESE !!! If you prefer Official Chinese Global rom, you must download a FASTBOOT rom (not recovery) , and flash it in fastboot mode, with MiFlash.

instead of beating around the bush, why not follow the official procedure of flashing an official miui rom
if you are coming from a custom rom, as specified herein?:

When can we expect official RR for mi max 2?
It was already available for redmi note 4 which is having the same processor.

You have to wait for custom Rom until miui release the kernel source which is must have to develop a custom one. please be patience...

If you flash rom with out error, Even no os installed warning, you can boot into system without problem.

I'ts not so hard is it ? You will have some problems with custom roms, cause they don't include one like MIUI roms.

Just flash as usual.
- Wipe data, cache, system (dont forget to backup your important files)
- Flash MIUI
- Flash lazy flasher (optional)
Keep in mind
If you flash global beta version, it will replace your TWRP, you need to flash your recovery by fastboot whith pc.
China version, cannot replace your TWRP.

Hi,
with the xiaomi.eu rom, you won't loose your recovery. Just follow instructions told by @MattHdH :
- Wipe data, cache, system (dont forget to backup your important files)
- Flash MIUI
Reboot.
Done !

Custom rom to stable

Hello,
I'am french and sorry for my very bad english.
i have buy the xiaomi mi 8 china Version. After waiting 360h for unlock bootloader i Do it and install xiaomi.eu rom (MIUI 10 beta). Now i would like to install the global official global beta rom
What Can i need to do?
Do it with TWRP and wipe data and dalvik cache and flash the global rom with TWRP and reboot?
No bootloop?
Or maybe use miflash?
What is the good method.
Do i need to use dm-verity for twrp and to doesn't brick phone or bootloop?
Twrp will be loose?
Sorry again, And thanks for all replies.

download the global beta miui 10 8.8.21. it's a zip file, here in xda
if it's a zip file always use TWRP.
if it's tgz file - use Fastboot ( Mi Flash tool)
make sure you are in latest twrp version and flash Force-encryption/DM-Verity after flashing rom.
don't ever try to lock bootloader and be careful when using mi flash tool it has option to lock so don't use it this option.

Thanks. And when i need to do wipe cache and wipe dalvik?
Cache before flashing rom?
Dalvik After dm-verity or After rom flash?

Redmi 4X: .EU don't wipe system / LOS wipe system (?)

Hi everyone,
I'm using Redmi 4X (China Version) currently with the latest 8.11.15 Global Beta ROM. I would like to flash TWRP again and go back to Xiaomi.EU ROM. I'm a bit confused because: If I want to flash LineageOS for Redmi 4X (santoni), in the instructions it says "wipe system" but in Xiaomi.EU they say "don't wipe system". So if I want LOS for now, and then Xiaomi.EU, who is wrong and who is right? Or will I have any issues if I wipe system?
Yours sincerely,
CyNote / peryson

Wiping system is must before flashing any custom rom.

In Xiaomi.EU site they are saying when you flash their rom, do not wipe system or persist! (I'm confused)
Because I wanted to try LineageOS, and in LOS site they say to wipe system.

You must need to clean flash (including wiping system) when switching between different ROM but you don't need to wipe system if you are flashing same ROM or it's update.
E.g. as now you are using MIUI 8.11.15, so whenever next update releases you can flash update without wiping system.
So if you want to flash Lineage OS and your device has currently installed ROM is MIUI then you'll have to clean flash including wiping system.
This same applies to all other ROMs. If currunt ROM and the ROM you want to flash are different then you'll have to wipe system too.
If you've already installed xiaami.eu ROM installed already then you don't need to wipe system, you can directly flash update/on top of it.
Xiaomi.eu and MIUI are two different ROMs.
MIUI is official ROM from Xiaomi and Xiaomi.eu is modified ROM from official MIUI ROM hence they are different and requires clean flash if you switch in between.
You'll have clean flash including wiping system in order to flash Lineage OS on your device.
Do take full backup of your data before flashing.
Hope it clears your doubt.
