Updating
If there's an update to Magisk, you'll get a notification from the Magisk app (if you haven't turned it off, that is). You can update through the app or download the Magisk apk from GitHub (never download Magisk files from anywhere else!), and flash in recovery (after changing the .apk extension to .zip). Make sure to read the release notes and the changelog, both can be found in the Magisk Documentation. Any modules you have installed may have to be updated to conform with possible changes to Magisk.Unsupported Magisk version
After updating the Magisk app you might get a message that the updated app doesn't support your installed version of Magisk. Here you have two options, both involving manually upgrading Magisk to a supported version. Download the Magisk zip and flash it from TWRP, or downgrade the app to a release that supports your current Magisk version and flash the zip from the Modules section of the app. This is done exactly like when installing a Magisk Module manually, by clicking the "Install from storage" button and selecting the zip.Updating issues
If you're having problems updating to a newer version of Magisk (bootloops, etc), start by disabling your modules, in case one or more of them are causing issues. This is easiest done by enabling Safe Mode or the ADB command to remove all modules (see Disabling/uninstalling modules manually). You can also try to uninstall Magisk and start over with a clean installation of the new Magisk version.MagiskHide or SafetyNet fails after an update
If MagiskHide or SafetyNet starts failing after an update to either Magisk, the app or both it's usually fixed by toggling MagiskHide off and on (also see ”Test MagiskHide”).Magisk not installed after updating
When updating Magisk there might sometimes be issues related to the Magisk app, where the app might report that Magisk isn't installed. If you have the app hidden/repackaged you might end up with two apps installed, etc.The solution is usually to uninstall the app (or both if that's the case) and install it fresh. If the app can't be reinstalled you might have to do some manual work to get things working. Take a look under "Can't install the Magisk app" for details.
If you experience the "Magisk not installed" issue randomly, see "Randomly losing root" for details.
