### USB Debugging (with security)

This requires root, shell access with su, and a way to edit text files as root. I used Termux and and android root file manager that can edit text files.

First, run the following command (su first, to switch to root):

    setprop persist.security.adbinstall 1

If you also want to enable "USB debugging (Security settings)", for granting permissions, simulating UI input, etc. via ADB, run the following command too:

    setprop persist.security.adbinput 1

Next, we need to edit the edit the file

    /data/data/com.miui.securitycenter/shared_prefs/remote_provider_preferences.xml

so that MIUI actually lets us do these things:

Add the following line to the XML file (with all the other ones, before the closing </map> tag):

    <boolean name="security_adb_install_enable" value="true" />

## TWRP

Was in TWRP 3.3.1-9  
To install the correct TWRP version, check the "base" of the TWRP indicated after the version number.
E.G. :  
`twrp-3.6.2_9-0-ginkgo.img` is a base Android 9-0  
`twrp-3.5.2_10-2-ginkgo.img` is a base Adndroid 10-2  
`twrp-3.7.0_12-1-ginkgo.img` is a base Adndroid 12-1  

Some Android versions cannot decrypt your data folder because of incompatibility issues. Simply downgrade to a lower Android base TWRP.

- Enter Fastboot to install latest TWRP

```shell
# To check current recovery tool (with phone powered up)
adb reboot recovery

# Boot to recovery
adb reboot bootloader
# Confirm correctly in fastboot
fastboot devices
# Install latest TWRP
cd "/home/wes/Documents/Cellulaires-ROMs/Redmi Note 8"
fastboot flash recovery twrp-3.7.0_12-1-ginkgo.img
# Shutdown phone then "Volume Up + Power" to enter recovery
fastboot reboot
```

## First time installation

You might need to use Lineage OS recovery the first time to initialize a factory reset. Simply follow the instruction here :
<https://wiki.lineageos.org/devices/ginkgo/install/variant1#installing-a-custom-recovery-using-fastboot>  
Sideload the custom ROM rather than Lineage.

## ArrowOS

- Boot in recovery
- Wipe data, cache, dalvik cache
- Flash latest android-11 firmware (Ginkgo | Willow)
  ```shell
  adb push Arrow-v13.1-ginkgo-OFFICIAL-20230829-GAPPS.zip /sdcard
  ```
- Flash ROM zip
- Format data (if encrypted)
- Reboot
- Configure system manually
- Install Magisk for root
  ```shell
  adb reboot recovery
  adb sideload Magisk.v26.3.apk
  ```

`No need to follow this, simply install by sideloading + app within OS`  
Since Redmi Note 8 has no ramdisk, a special guide is required.

  - Install the Magisk app from the official git repo.
  - Push installed recovery locally :
     `adb push twrp-3.7.0_12-1-ginkgo.img /sdcard/Documents/`
  - Execute Magisk app
  - Press the Install button on the Magisk card.
  - Enable "Recovery Mode" under Options
  - Choose "Select and Patch a File" under Method, and select the local recovery image.
  - Retrieve the patched image locally :
    adb pull /sdcard/Download/magisk_patched_[random_strings].img
  - Reboot in fastboot and flash recovery :
    fastboot flash recovery /path/to/magisk_patched.img

- Configure Magisk
  - Settings/Systemless hosts
  - Settings/Zygisk
