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.
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.
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.
And then reboot to TWRP, wipe data partition.
Edited:
You can find your vbmeta in fastboot ROM of laurus.
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.
Fastboot of laurus
Fastboot of laruel_sprout
For people who prefer stock A3 Android One ROM, Here is the method I've tested

In short, laurus MUST flash A/B image instead of A only, just like Mi 9 (cepheus) and Mi Mix 3 (perseus).
