How is GSI support for Xiaomi Mi 9 (cepheus)

We already know this phone is arm64,
the GSI rom AOSP v112 has support for this phone.
But how is the rom behave? What works and doesn't?
How are other GSI flavours doing? Like RR, AEX, HAVOC,....
[NOTE: For those who are interested i'll change this post to some GSI guide cepheus,
as soon as i recieve my Mi 9. But until then i'll hope for some of your feedback]

See this: https://github.com/phhusson/treble_experimentations/wiki/Xiaomi-Mi-9
and these two: https://forum.xda-developers.com/showpost.php?p=79284072&postcount=46, https://forum.xda-developers.com/showpost.php?p=79295919&postcount=53
It shoudn't be needed to write a guide

a video guide would be interesting
I usually used twrp to flash the Gsi file but now I didn't understand what steps should be taken

tried Foloko, RR trebles and it's entertaining as STDs.. couldn't add Gapps for hours and never managed to using 2 very different TWRPs we've got, tons of tricks, or adding stock system/vendor.
I don't understand the assumption "Please don't use third-party custom rom (e.g. Xiaomi.eu roms) as the base rom. Some hacky roms have wrong (unofficial) fingerprint and GSI can't detect what device you are using. ", ok, what should be in the phone then?
After some attempts Phh treble from post 60 installed, greeting me with "There's an internal problem with your device. Contact your manufacturer for details.", some vendor nonsense. After reboot i cannot log in, as fingerprint overrides the letter i need to type the password. omg. So i have to reflash.
update: since Phh was ultra vanilla with literally 2 extra settings, tried RR, same greeting, no fp, and no swipe to apps there, i don't really beg for their modifications as i have Xposed Edge for this. Finally went back to Floko knowing how to fix gapps problem, it's got best navbar solution, although with tons of bugs (contradicting navbar user actions, non responsive gestures, nonresponsive buttons), no tap2wake, AOD sucks, fp sucks too, produces blinking screen.
Looks like trebles are unusable, time to go back to XIAOMI EU... so much for "don't need device specific ROMs".

You have to flash *official* MIUI rom (China or Global depend on your hardware, and it's better to flash developer version to get latest update).
To install GApps, you have to do Wipe -> Advanced wipe -> Select system -> Resize, then Mount -> mount system, then install GApps zip.

dear mod please close this one, there seems to be already a conversation about this

tried to do that, tried to install arm64 Gapps, I'd get an error saying my system is arm, so i install arm gapps, they do get "installed", but when i reboot, there is no gapps at all.
edit: arm64 gapps worked when used LR.Team/wzsx150 twrp.

which Global please? this is the link http://en.miui.com/download-361.html claiming to be Full Rom, but the zip is similar to EU version, just a patch.. just tried it, then flashed EU and magisk and getting "can't connect to camera". i was thinking i need to flash some bigger package (.tgz file), but there's none published and going throught the million childish looking forums on eu.miui.com, not sure.. would like TWRP way. perhaps format system?

thanks but both links redirect me to http://www.miui.com/ in chinese where i can browse to quasi-full roms again. strange.
btw i'm a fan of your kernel except it causes "can't connect to camera".. after many combinations of flashing i tried skipping the kernel (v01, or v02 or any kernel), and camera is back. however without Night mode this time...
update: found stable ROM at least https://c.mi.com/thread-1907373-1-0.html
update: somehow i trust this is the legit link to develop ROM http://bigota.d.miui.com/9.3.1/ceph....1_20190301.0000.00_9.0_global_cdb3885bac.tgz

Hey,
Could you make your magisk patch to not require pressing FP scanner twice for FP to register?
Without the patch, works fine from first try, but with it, two presses at least are needed Everytime.
Thank you!

Please help to install ROM in [Raphaelin]

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

Did you do FORMAT Data (not just Wipe) when you installed your custom ROM, and before rebooting?

Can't boot into new rom

I have TWRP on my Mi 9T Pro but whenever I try to boot into a new rom it just boots back into TWRP, I think it's because I accidentally wiped everything including my kernel, but I'm not entirely sure, there's no errors when I try to install one, I've tried multiple, my phone doesn't have an OS installed ATM, no MiUI, I've tried flashing stock rom but that also doesn't work. I really don't know what to do.

Restore MIUI by flashing a MIUI fastboot ROM.
Get the fastboot ROM from here
https://xiaomifirmwareupdater.com/miui/raphael/
Choose the fastboot ROM for the phone you have (European or Global). Make sure it is a fastboot ROM, not a recovery ROM.
Use this guide to flash it
https://c.mi.com/oc/miuidownload/detail?guide=2
View the page in desktop mode if viewing on a phone.
In step 5 make sure you change flash option to 'clean all' before hitting flash. This is three radio button options at the bottom of the flash tool. The default locks the bootloader, so you need to change it to keep the bootloader unlocked.
After doing this boot into MIUI at least once before trying to install something again.
When flashing a custom ROM over MIUI you need to format data in TWRP.
After installing TWRP, boot into it a do the following.
Perform a factory reset.
Format data - make sure you format, not wipe, need to type 'yes' to confirm.
Reboot back into TWRP - this makes sure the data partition is properly mounted after formatting.
Now flash the ROM you want and GApps if needed.
Reboot to system and it should be good.
Flash Magisk if needed.
Do not wipe anything else in TWRP. It's not needed.

First Learn Basics while messing with your device.
Kernel is a part of ROM's Zip,
So even if you wiped kernel(so called boot), it will again gets re flashed with new ROM.
Second your problem is,
You are booting into wrong partition.
I am not sure , what you did.
But Mi9TPro has two partitions, Google's new A/B partition table for Android.
And you may have wiped both Flashed A(example) and booting into B.
Therefore it is not booting properly.
Ask in Telegram group for faster solution.
Or wait here for better solution in reply.
OR
Simply flash Fastboot,
And then try everything again.
Ans from next time, read everything step carefully and then proceed.

It's an A only, system as root device. It is not an A/B device.
This is why MIUI updates need to be installed in system recovery. It does not install updates when the system is live.

if it's booting back into twrp. It's usually one of the three mistakes.
1. wrong vendor
2. didnt flash dfe
3. flashed dfe for stock rom
4. encrypted, so format data partition.
you can follow the guide: https://forum.xda-developers.com/k20-pro/how-to/simple-beginners-guide-to-raphaelin-t4020543
also, k20p is A partition only, not dual.
kernel is included with rom.

You don't need to flash dfe. I've not yet come across a situation where it is required. Flashing dfe will make life easier, at the cost of greatly reduced security, but there are always options to do what you want without flashing dfe.

flashing custom rom ( pixel experience plus edition) Keep Booting Into TWRP Recovery

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.

flashed stock miui rom for now. Will tap into pixel rom in few days.

now that I think, I think I did a blunder, thinking I was in A12. Can you point me to A12 firmware for Redmi k 20 pro? I"m looking into https://miuirom.org/phones/xiaomi-12, but they seem to be recovery and not firmware. I'm not sure if recovery comes with firmware. As I need to format to install, will the firmware stay or not?

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.

I need some well working GSI's for my A605FN

Android 10 is too much for this device and my 3gb of ram cant take it. I dont have time searching for well working GSI's to this phone. I need well optimized system that will use minimum ammount of resources. Thanks.

I need well optimized system that will use minimum ammount of resources. Thanks.

Just try that Lineage R mod - it should work fine. However if you want so old builds, then there is best list with Android 8 Oreo section:

When i try to install lower android version than 10 my phone boots in download mode... Yes, regular odin mode, no errors, etc. Please help, i want to get rid of that android 10 no matter what version it is, even LineageOs or AOSP, its still android 10 that use a lot of resources to work smoothly

1. Download this and extract.
2. Go to TWRP.
3. Follow this guide (flash this in TWRP, not in Odin).
It should work well. Older Android versions may require older kernel versions to run or you just chosen wrong builds (it needs to be A/B arm32_binder64 (A64 - not arm64) vndklite).
In case that Lineage R mod is not smooth enough do the same with other GSI's from the list from my previous post (always choose arm32_binder64 vndklite (A/B) builds). Some will be lightweight enough for your needs.

Ye i know build for my phone . I will try the GSI you linked but which gapps should i use to this system?

And i have another great idea, what if i just not install the gapps and run clear CLEAR android

Hmm... Also i can install the most important gapps, I didnt think about that, that should use very small ammount of ram, cpu, etc.

Just use build I linked above. It has integrated Gapps and passes needed certfications out of the box. You can also download vanilla build and flash pico gapps yourself. However option with integrated gapps is just fine and sufficient. Read whole thread - author had the same problem as you and solved it by flashing Lineage R mod with integrated gapps - it's the most simple way.

Idk why but when i flash this GSI with no error and then i try to boot to the system it goes download mode. I think i know how to flash GSI's, I'm doing it 100% right. I flashed it in every possible way. It is getting boring

Well, flash maybe at first stock firmware via Odin to ensure that kernel and vendor partiton are untouched. And then flash GSI in TWRP two times like it was said in guide.
However the most common cause of such effect (booting to download mode) is just wrong build (wrong architecture - you need to always download arm32_binder64 (A64) builds).

I already tried to flash GSI after flashing ROM via Odin3. Still booting to download mode. Im 420% sure i downloaded right build.

Well, I'm out of ideas. However you can still try to resize system partition in TWRP to make it a bit bigger and then try to flash GSI image (two times). You can also just try to play with different GSI's from the GSI list - just look for the smallest images and try to flash them. If some will properly boot then just go back to TWRP and flash rest of your needs (pico gapps, Magisk, etc.).

I will try that in future
