Step-by-step guide on how I install Magisk using adb

sideload-magisk.md

Install Magisk via Sideload

💻 => the device running adb (usually a PC)
📱 => the device where Magisk is going to be installed (usually a Phone or Tablet)

• 📱 Install Magisk App
• 💻 Download Magisk
• 💻 Rename .apk to .zip
• 💻 Reboot device in Sideload mode
• 💻 Sideload Magisk
• 📱 Complete the Magisk installation (if needed)

📱 Install Magisk App

The app can be found on F-Droid:

• https://f-droid.org/en/packages/com.topjohnwu.magisk

Notes

• 📱 if an older version is installed, update it directly from the Magisk app

💻 Download Magisk

Download the latest Magisk .apk from the official GitHub repo:

• https://github.com/topjohnwu/Magisk

💻 Rename .apk to .zip

mv Magisk.VERSION-NR.apk Magisk.VERSION-NR.apk.zip

💻 Reboot device in Sideload mode

sudo adb reboot sideload

Notes

• 📱 USB debugging mode must be active (under Settings > Developer Options)
• 📱 the device running adb (💻) must be approved on the receiving device (📱), else no actions will be taken
• 💻 in case something goes wrong, kill the running server and start over

  sudo adb kill-server

💻 Sideload Magisk

sudo adb sideload /path/to/Magisk.VERSION-NR.apk.zip

Notes

• 📱 signature verification might fail, I bypass it to install Magisk anyway
• 💻 adb might show something like Total xfer: 0.90x, this is fine
• 📱 reboot to system once done

📱 Complete Magisk installation (if needed)

Magisk might need to be re-installed "internally".
This can be done directly from the app.

Notes

• 📱 a popup will appear
• 📱 re-install Magisk using the recommended option
• 📱 once done a reboot option will be shown, reboot

Thank you very much! This saved me after installing (not yet rebooting!) an OTA-update of /e/OS custom ROM killed the running system. So I could not patch the inactive slot with the Magisk App. Your description worked perfect. ❤️
The phone was still reachable via adb. (At the second time I used this procedure I had to lock and unlock the phone to have it reachable with adb.) I first rebooted to sideload mode and installed Magisk as described and afterwards rebooted to the new system.

Here this was not necessary. I just accepted the verification failure during installation and everything worked well.

you welcome @bege10 I'm glad this was helpful :)

BTW, I forgot to rename the apk to zip and it still worked. It seems not to be necessary.

thanks
