Same installation process as #222, I will do that today.
You will be able to test it with branch dev-flash-additional (some already / not already merged PR are required to support Xiaomi devices, will all be merged with next update iirc)

first of all sorry for my broken english
im not that technical so idk what a branch is :p
and 2 : i dont have a custom recover installed or have my bootloadr unlocked
how can i do them ?
thanks

Ok, no problem! If you want to test, we can provide you a running version of the program (no need to do anything, just click it and it will start)

But before that, to install custom ROM, you will have to unlock your bootloader. This will reset your device. Make sure you have a backup! There are the steps :

• Create a Mi account on Xiaomi’s website. Beware that one account is only allowed to unlock one unique device every 30 days.
• Add a phone number to your Mi account, insert a SIM into your phone.
• Enable developer options in Settings > About Phone by repeatedly tapping MIUI Version.
• Link the device to your Mi account in Settings > Additional settings > Developer options > Mi Unlock status.
• Download the Mi Unlock app with the link bellow (Windows is required to run the app), and follow the instructions provided by the app. It may tell you that you have to wait, usually 7 days. If it does so, please wait the quoted amount of time before continuing to the next step!
• After device and Mi account are successfully verified, the bootloader should be unlocked.
• Since the device resets completely, you will need to re-enable USB debugging to continue : Settings > Additional settings > Developer options > USB debugging

Hey, thank you that you want to test the installer with your device :)

I can only recommend to backup everything in a manual way. Connect your device to a computer and copy what you want to keep. Automatic backup solutions don't work well from what I can tell. In general on Android and especially on custom ROMs. Only use them when you verified they work for your setup.
Long story short, copy everything you can to your PC, everything else will be gone.

thank you
after backing my data up , i tried to test it but it says i need to a12 installed , i currently have a13 installed on my phone
do i have to downgrade ?

If you are trying an Android 12 based ROM (like LineageOS 19.1), I guess you should be on Android 12. But thats probably a question @anon1892 can answer better.

do i have to downgrade ?

You have to be on the same Android version you want to install (or last available for phones no more supported by the manufacturer) (unless exceptions)
It's generally written when you download your ROM : use the version developers recommend

Examples :
For Lineage 19.1, Android 12 is needed (so you have to downgrade)
For crDroid (A13), latest version (Android 13) is good
