Installing magisk with Android 11 Is there a problem with, or something missing from, the steps at this guide for installing Magisk on Android 11?
Specifically, in step 13, it says to flash the patched boot image (patched by Magisk Manager) to the phone, with
fastboot flash boot patched_magisk.img

followed by
fastboot reboot

And then to verify root in step 14 by checking in the Magisk Manager app. But doesn't step 13 reset the phone, so the installed apps like Magisk Manager are also gone?
Certainly not. It's safe
All that you are doing in this step is to

Check if your device is recognized in fastboot mode by fastboot devices

Replace the boot image by the patched boot image on your computer by
fastboot flash boot xxx.img.

fastboot reboot will boot you into OS where you can verify root as next step recommends.


This the normal way of rooting using patched images and will not affect your installed apps. See Magisk official documentation
