After booting phone works, do following:

  • install magisk apk from magisk website
  • use boot.img from e os downloaded zip of your installed version to patch that image
  • transfer it to your pc
  • boot into fastboot
  • adb reboot bootloader
  • fastboot boot /path/to/patched_boot.img
  • boot will take some time
  • then in magisk use direct install
  • problems might occur if slot for boot image is changed

Hide Root:

  • check in settings the zygisk mode and configure deny list
  • additional might be necessary to disable magisk temporartily
  • Carefull to always enable again before loosing root rights, but root rights are stored if you do not unintall an app, so can keep using without having magisk enabled
  • pm disable com.topjohnwu.magisk pm enable com.topjohnwu.magisk
  • Also see tasker for shortcuts

Automate Root via Script #

  • If you update your FP4 with /e/OS installed, the root via magisk will be removed
  • To root my phone again, I wrote a script to automate this process
    • It downloads the latest FP4 /e/OS image
    • Extracts the boot.img file
    • Connects to the phone via adb and patches it via magisk command line tool
    • And then boots the phone into fastboot to finally flash the new boot image
  • The script is available in my personal linux-scripts repo

Recover Encrypted data #

SSH Server on android #

Server

  • Install the simpleSSHD app and start it
    • in settings change to entry /bin/su
    • this way you are logged in as root if using ssh into your phone (needs rooted phone)
  • create a authorized_keys file in the folder, which is set in the simpleSSHD settings as a home directory to look for ssh keys
  • set a static IP via your router for your phone to always access the same ip adress
  • log into your phone via ssh ssh root@192.168.0.23 -p 2222

Client

  • Use the pkg manager form termux to install the ssh package ssh-keygen command to generate a ssh key
    • Now you can put the public key into your authorized_keys file on the PC, you want to have access to via ssh
    • Now use termux ssh command
    • /data/data/com.termux/files/usr/bin/ssh root@192.168.0.100
