this is a mirror + tutorial. i will try to credit as much as possible.

extracted files + roms

unlocking bootloader

install usb drivers https://mtkdriver.com/

first install python3 (plenty of vids)

install git

commands to run:

git clone https://github.com/bkerler/mtkclient
cd mtkclient
pip -r install requirements.txt
git clone https://github.com/coloredmarble/redmi_9a_mtkclient
cp redmi_9a_mtkclient/* .
# power off phone. press volump up and volume down at same time. connect phone to usb cable
py mtk da seccfg unlock --preload preloader_k62v1_64_bsp.bin --loader n.bin

for me it took like 5 hours to figure this shit out. worth it

firmware

firmware in releases. pick one

roms

Arrow OS available in releases. flash firmware instad of miui from releases

flashing arrowOS

MTK devices tends to be a little whiny:

1. wipe data + cache + dalvik
2. format data
3. flash arrowos
4. flash magisk (i didint select wipe cache/dalvik. i dont think you should)
5. reboot to system and install magisk
6. install magisk module microg https://github.com/friendlyneighborhoodshane/minmicrog_releases/releases (recommend nogoolag)

it may or may not boot depending on the phone's mood

also if you manage to boot. it works insanely well on a phone with 2 small bricks of ram
