### 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
- Install Magisk Modules

## Check logs using logcat

- Find name of app
- filter with the name

```shell
$ pm list packages | grep -i seed
package:com.stevesoltys.seedvault
$ logcat -e seedvault
# or use a simple grep
logcat | grep 'vault'
```


```shell
# This is specific to SeedVault (https://github.com/seedvault-app/seedvault/blob/android15/logcat-verbose.sh)
set -ex

adb shell setprop log.tag.BackupManagerService VERBOSE
adb shell setprop log.tag.BackupManagerConstants VERBOSE
adb shell setprop log.tag.BackupTransportManager VERBOSE
adb shell setprop log.tag.KeyValueBackupJob VERBOSE
adb shell setprop log.tag.KeyValueBackupTask VERBOSE
adb shell setprop log.tag.TransportClient VERBOSE
adb shell setprop log.tag.BackupAgent VERBOSE
adb shell setprop log.tag.PMBA VERBOSE

## Navigate through the slots

To flash permanently, first switch/select any slot you want or it will **automatically flashed to the active slot**.

fastboot set_active other  //switch to inactive slot
fastboot set_active (a or b)  //switch to specified slot
```

## Check current slot and baseband version

```sh
adb shell getprop | grep -Ei '(gsm.*baseband|slot_suffix)'
```

## Have both slots (A/B) with same verity/verification configuration

```sh
fastboot flash vbmeta --disable-verity --disable-verification --slot=all vbmeta.img
```

## Secure phone (to review)

```sh
#!/bin/bash
adb root
adb remount
adb pull /system/build.prop .
sed -i "s/ro.secure=0/ro.secure=1/" build.prop
sed -i "s/ro.debuggable=1/ro.debuggable=0/" build.prop
adb push build.prop /system/build.prop
rm build.prop
```
