Hey guys,
Although Mi CC9e (laurus) has been released for some days, there's few discussion on this device. The reason why I bought laurus is because I think it will share a community with Mi A3 (laurel_sprout), and it's easier to get laurus in China (with 6GB RAM). And indeed, laurus use exactly the same kernel with laurel_sprout. Most people think laurus is A only and laurel_sprout is A/B, which is almost, but not entirely correct. Devices launched with Android 9 are mandatory to use system-as-root.
In previous versions of Android, devices that didn't support A/B updates could mount the system image under the /system directory. In Android 9, the root of the system image is mounted as the root of the device.

In short, laurus MUST flash A/B image instead of A only, just like Mi 9 (cepheus) and Mi Mix 3 (perseus).
I assume that your'phone is unlocked and you've configured ADB and Fastboot.
So, let's start.
1. Flash TWRP
Reboot your laurus to Fastboot with Power + Volume Down.
There's a available TWRP from Chinese developer LR.Team
Download Link
The batch script is in Chinese, but I'm sure you know what to do if you're familar with Fastboot.
Code:
fastboot flash recovery recovery-TWRP-3.3.1-0914-XIAOMI_CC9E-CN-wzsx150.img
2. Flash BeastROM 1.6
Although BeastROM 2.0 has released but I can't get it work. It just display Mi logo and then jump to Fastboot. Most other GSIs won't work as well, it dosen't boot at all. So the only choose is BeastROM 1.6 for laurel_sprout @mdeejay.
BeastROM 1.6
unzip it, and what we need to do is flash system.img ONLY.
Code:
fastboot flash system system.img
And then reboot to TWRP, wipe data partition.
Edited:
You can find your vbmeta in fastboot ROM of laurus.
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
This command is NOT NEEDED if you can disable dm-verity via magisk. You can't boot without disabling dm-verity (stuck on Logo). I don't know how it works. Need some help from devs.
3. Flash Magisk
You HAVE TO flash magisk, or it will stuck on boot animation.
You can do it by "Install Root" in Advanced of TWRP.
Or do it manually by flash Magisk.
4. Flash GApps (Optional)
OpenGApps
Just Flash it in TWRP, nothing more to say. Maybe you need to wipe data again.
I think everything is perfect for now, execpt it's Android 9 instead of 10. At least you can get most of features in Mi A3 and get rid of stupid MIUI
Some stupid idea: for people who wanna get MIUI in laurel_sprout, you can flash system.img in fastboot of laurus. I don't think it will work but it worth trying.
I've tried flashing laurel_sprout image into laurus, it can boot, but it won't work. Screen blinks and it get stuck on welcome page, touching works though.

For people who prefer stock A3 Android One ROM, Here is the method I've tested

mi cc9e can use stock rom of mi a3 without root, this mean bank app will work perfect
1- flash full rom with miflash (any lower version will not boot) http://bigota.d.miui.com/V10.2.13.0...FMCNXM_20190830.0000.00_9.0_cn_fc9f51f46d.tgz
2- download rom of mi a3, extract file system.img only
http://bigota.d.miui.com/V10.3.4.0....0.PFQMIXM_20190815.0000.00_9.0_00838b4c0e.tgz
3- go to fastboot and flash (vbmeta of micc9e)
fastboot flash system system.img
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot reboot

Are your device Mi CC9e instead of Mi A3? Make sure you're flashing BeastROM 1.6 instead of 2.0 or you'll get stuck on fastboot. And maybe you need to format your data partition in TWRP.

Power and Volume up can make it boot into Recovery.
But if you flashed dtbo and vbmeta of BeastROM 1.6, or maybe you wipe your system partition. , it will be stuck at fastboot and cannot boot (or enter recovery)
One way to fix this is disable dm-verity, just use magisk, you can do it by "Install Root" in Advanced of TWRP. (Flashing magisk manully does the same job)
(However, you can't enter TWRP, so this won't work. )
Another way to disable dm-verity is flash vbmeta with --disable-verity --disable-verification, but I'm not sure whether it works.
Your best chioce is flash the fastboot ROM of laurus and do it again. Remerber to flash magisk in TWRP after flashing system.img, I made a mistake that magisk is not included in BeastROM and you must flash it to disable dm-verity or it will never boot.
im fix it and its ok now,how,i dont know
finaly miui gone,yyyuuhuu
If u update magisk and stug on bootloop,u can start on twrp and flash magisk manualy and reboot in beastrom again

Just dont use or update to magisk 20,stug on bootloop

Some of us Mi A3 users want to use Miui 11 from CC9e, how possible is that. Could you give a tutorial?
Android one is snappy on mi a3, with 6g ram on CC9e it will be really smooth.

I wanted to create a discussion for flashing GSI's and experimentations with Treble on our Pixel 3a. If you're unfamiliar with GSI's and Treble, please check out the wiki and FAQ here. Not all GSI's run flawless on our device, as to be expected, there WILL BE bugs here and there. These methods will wipe userdata, so backup all of your important data before attempting to flash a GSI. Make damn sure you have a way to recover your device in case something goes wrong!
What you'll need:
Fastboot and ADB installed correctly.
Factory image for Sargo - get it here.
An unlocked bootloader.
A GSI to install.
(vbmeta.img / vendor.img can be extracted from our factory image.)
Auto install a GSI:
The Universal Auto GSI Installer by @zedomax works for our device with all the GSI's I have tried from XDA. His instructions and video tutorial is included in the thread. The script is very easy to set up and use to install a GSI.
Manually install a GSI:
Code:
From stock Android 10 or 11
Boot into fastboot, then to fastbootd:
$ fastboot reboot fastboot
Disable verify boot (AVB) by flashing vbmeta.img:
$ fastboot --disable-verification flash --slot all vbmeta vbmeta.img
Find your current slot:
$ fastboot getvar current-slot
Delete the product partition to free up space for the system partition (Current slot):
$ fastboot delete-logical-partition product_a
The postfix _a should match the slot ID from our last command.
Erase the system partition:
$ fastboot erase system
Flash the GSI:
$ fastboot flash system system.img
This will take a bit.
Now wipe userdata and reboot:
$ fastboot -w reboot
Other resources regarding flashing GSI's:
Google's instructions.
Known issues and releases.
Android 11 Installation and info, translate to read.

I've MSM'ed about 8 times today. Every single time I attempt to flash recovery, no matter which recovery, it overwrites the system and upon rebooting to recovery through fastboot, it permanently stays in fastboot. I can MSM out of it. I've tried conversion MSM, temporarily booting recovery, flashing firmwares, resetting, wiping. I cannot fix this. I have spent over 11 hours trying to troubleshoot this. Google comes up with useless results. This is the first time I've not been able to recover from a situation with this phone. Please, if you have any ideas, shoot. The model is kb2007.

try a fastboot boot twrp ( https://github.com/ApexLegend007/twrp_device_oneplus_lemonades/releases ) and try factory resetting it then see if you can switch your partition from a to be or b to a then try msm flashing ( https://androidfilehost.com/?fid=17248734326145733797 )

I can't even boot TWRP, it just shows the Oneplus logo and the"fastboot mode" thing forever. It's been 10 minutes now.
If you've used MSM then you're on OOS 11.
I assume the phone boots properly after MSM.
On OOS 11 you can only use TWRP 11 from https://dl.twrp.me/kebab/
And you can only use TWRP 12 on OOS 12 from https://forum.xda-developers.com/t/...in-recovery-project-8t-9r-2022-07-27.4473983/
PS: and you should have posted this in the 8T Q&A forum.

OOS is 11.1.0.2.KB09CB
I've tried TWRP 3.6.1, 3.6.0, and 3.6.2
OOS does boot cleanly.
Phone is KB2007.
The bootloader is unlocked.
I've truly never had this problem before.
You'll probably have to upgrade to the latest version of OOS 11 (or 12) before TWRP will boot.
I have an idea, if you are in fast boot mode then you can flash everything manually. ( https://forum.xda-developers.com/t/oneplus-8t-rom-ota-oxygen-os-repo-of-oxygen-os-builds.4193183/ ) there's only international version (kb2005) it can work with that. Just use payload dumper to extract all the .img by dragging and dropping the payload.bin unto payload dumper after extracting them all into a folder then use the commands to flash them all with adb. Then reboot to recovery, factory reset, and MSM tool back to TMO.
do these commands one by one replacing the .img with the location of the .img. actually, just drag and drop the file after. ( ex: fastboot flash logo C:\Users\???\Desktop\???.img )
Just an extra recommendation to wipe the device
( Fastboot -w )BEFORE THE OTHER COMMANDS but you don't need to if it works without wiping.

fastboot --disable-verity flash vbmeta_system vbmeta_system.img
fastboot flash vendor vendor.img
fastboot flash xbl xbl.img
fastboot flash xbl_config xbl_config.img
I'm way too inexperienced with this but if anything goes wrong you can MSM tool back to fastboot.
honest recommendation, just use TMO to International MSM tool after. unless you want to keep it TMO (kb2007)

Sorry I'm very bad at this. I was thinking you didn't even boot properly.... just update to the latest using oxygen updater or the systems bultin update... Im a moron and ill be leaving that up there.
Hi! My goal is to install twrp recovery on my Oneplus 6t but when i flash it with the command fastboot flash boot twrp.img it does just boot into fastboot mode and the OS is deleted. i can’t use the command fastboot flash recovery twrp.img because i believe i have an A/B Partitioned device because everytime i use this command it says soemthing like: can’t find recovery_a. I can‘t use the command fastboot boot twrp.img because everytime i use this command the phone is stuck on the fastboot splash screen. I need help!
You should flash a fastboot rom of your device to fix this problem
The command is fastboot boot twrp.img. You can only boot it not flash it from fastboot. Once In twrp you can make it permanent in the settings
