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?:
http://en.miui.com/a-234.html
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 dont know if this is the right place to post this issue,sorry if this violates any rules
Recently I've shifted to custom roms on my device.I've always wanted to use one of those 9.0 ROM's.I tried 2 flavours-Pixys and Havoc.Both based off 9.
I tried flashing it with TWRP 3.2.1-0,as soon as I installed and rebooted it shows me Decryption failed and proceeded to factory reset my device.I had to repair my phone's file system to EXT4 to correct it and install an 8.1 based rom
Since I thought it might have to do something with TWRP, I tried RedWolf Recovery and tried installing Pixys and Havoc only to return to the same "Decryption Failed" issue.
Is there something different that I am doing?Can anyone help me in this regard.
Also,Im not able to install Magisk, recovery shows me Error-1 Couldnt mount vendor partition.What's the solution to this?
Did you tried another recovery? Try Batik Recovery!

Hey there, how about u try to install Pitchblack twrp the latest one and install Pixel experience pie riva, it can be used for rolex also because the developer make the rom to unified for both rolex and riva. Then install the magisk after that. I've been using pixel experience pie for a month and it is so far so good.

An update
I installed Batik recovery.Magisk could be flashed but Im still getting the decryption unsuccessful message when I install Pixys
Solved Magisk Error!
I've been using Pixys OS on my Redmi 4A and it works fine smoothly. I recommended to clean wipe before installing. Android Pie us amazing and I've installed stable version. Do backup before clean wipe.
For Magisk I recommended this: https://freaksterism.blogspot.com/2018/10/solved-cannot-mount-vendor-magisk.html?m=1
It worked for me. Also go through this step before any custom ROM. Do let me know the status

to solve decryption unsuccesful message, format data (Wipe>Format Data) after installing the rom, make sure you backup your internal storage coz Format Data will also ERASE the internal storage. This how i got over the decryption unsuccessfull message. hope this helped.
You have two problems.

You need to flash the twrp separated vendor version by my friend Offain https://androidfilehost.com/?fid=962187416754475993
The other problem with the decryption:
You must enter in the twrp press wipe and format data. Type yes and then reboot into twrp again. After that flash the rom and gapps and you will not have the decryption problem again

I had the same problem. Its because your phone is encrypted. The only solution I found is to boot the device into fastboot and using command: [fastboot format userdata] on PC. This will wipe all data off your phone so do backup. It removes encryption and now you can install any custom rom.
Decrypt ur phone first then flash, use twrp vendor

Format Data was the only thing that worked for me. First backup everything on your mass storage.
Please help me. I can't seem to understand what exactly I need to do in order to install a custom ROM on my K20 Pro (Global 10.3.5.0.) I have tried following this (https://forum.xda-developers.com/k20...0-pro-t3953844) post thoroughly and others as well, but can't seem to exactly understand what I am required to do. Most custom ROM's state [Raphael], but as I purchased this device in India, it would most probably be [Raphaelin], after unlocking the Bootloader and installing TWRP, am I supposed to flash a Custom ROM (for ex. Lineage OS) directly or would I have to install a ROM which would make my device [Raphael]? Vendor and Firmware have gone over my head, I do not understand what I need to di. If someone could help me out, It would be mean a lot. Thank you.

If you're running stock MIUI and haven't moved to any custom MIUI's till date then you can straight away flash LOS. Moreover, most of the custom roms work on multiple vendors irrespective of whether it is a China Vendor or India or Global. It doesn't matter till the time the developer specifically asks you to be on a particular vendor.
Vendor isn't a dreaded thing. It's just the drivers needed to run the various components in the device (BT, WiFi etc). Till the time you don't wipe the vendor partion in twrp, you would always be good to go. You could carry on flashing custom roms w/o careing about the vendor.

Thank you very much for your reply. So, just to check if I have understood correctly. I can just install TWRP and then flash Lineage OS straight away, right? I checked (https://forum.xda-developers.com/k20-pro/development/rom-lineageos-16-0-t3965311), and it mentioned:
Instructions :
Download the latest build and GApps
Reboot to recovery
Flash proper vendor and firmware
Flash the latest build and GApps
Reboot
What is "proper vendor and firmware"? And would I also be required to flash this?
Thank you.

Go back to the Lineage instructions and read immediately below that. It starts P.S.
It explains exactly proper vendor and firmware means.
No you won't need to install anything for this step

Nope ! You don't need to flash vendor + firmware as you already running an untouched stock MIUI build. That is for people who are coming from either modified MIUI builds (EU, Miroom etc) or custom roms with a different vendor (India device running on China Vendor)
Custom roms don't carry the Vendor Firmware files and you can only modify the existing Vendor when you move to other region stock or custom MIUI roms.
Back up your data on Internal storage to a safe place either on a PC or OTG. Skip this step if you have nothing important.
Boot In TWRP
Wipe System, Data , Cache , Dalvik
(Don't reboot at this point, Not Even a Recovery reboot)
Flash LOS
Flash GApps
Go to Advanced Wipe and Format Data by typing Yes
Reboot

I was using pixel experience ROM for some time and I tried to update to the latest plus edition. The installation guide recommended full format data and flashing. I did as instructed. Now I'm stuck in booting into TWRP recovery. I looked up a few kinds of stuff and none of them worked. Is anyone else facing the same problem? has anyone got a working fix? I tried removing the TWRP folder, re-flashing TWRP with TWRP and orange fox recover, and then flashing ROM. non helped. got a broken phone now any help is appreciated.

Wipe everything, system, vendor, internal storage, dalvik, cache via advanced wipe, then flash firmware and vendor or if your rom has included firmware then just flash the rom directly. Try to boot into OS if it still bring back to twrp then again repeat the above steps and this time flash stock vendor and firmware from mi website and try to boot into OS.

Why bothering to manually search here and there for official ROMs
Install the app:
MIUI Downloader - Apps on Google Play
MIUI upgrade app for Mi users.
play.google.com
and the app will show you links to download the latest Global, EEA, etc, zip/recovery or tgz/fastboot, or you can scroll through the older versions and pick an older if you wish
Btw, latest are MIUI 12.5, A11 - there are no official A12 ROMs for Mi 9/Redmi K20 line of models
Even if they receive MIUI 13, it will be (for some already released, but eg China only, etc) it will be A11
Same issue, I guess this is it for me. Time to buy a new phone rather than accidentally losing data from time to time with custom ROMs. I wonder if they didn't know such issue exists before releasing it to the public.
