After successfully flashing this ROM and gapps, get the latest magisk from the
GitHub repo:
Download the apk and create a duplicate.
Rename either file so it ends with .zip and you should now have two files:
> Magisk-v25.2.apk
> Magisk-v25.2.zip
One of the files needs to be a ZIP, otherwise you can't flash it.
> If you can't see file extensions, you need to enable it under the Explorer (View tab at the top).
Reboot to recovery and flash the Magisk-v25.2.zip file.
If it doesn't automatically reboot to CherishOS, do it.
In the main screen it should appear a new app. If it doesn't, manually install the Magisk-v25.2.apk file.
It might prompt you for some needed patching, say yes. The phone will patch itself and reboot.
Then you'll be rooted.
LMK if you need more help!
