Magisk Issues


Bootloop

If you end up in a bootloop when installing Magisk, flash the Magisk uninstaller zip in recovery (you migth also have to flash a clean boot image, which will help if there's something wrong with the boot image on your device) and start over (for bootloops occurring after installing a Magisk module, see "Module causing issues"). If the uninstaller fails, just flash your unmodified copy of the boot image and you should be good to go. There’ll probably be some leftover files and folders from Magisk laying around in /cache and /data/adb, but these can be removed manually.



It is also possible that the device is refusing to boot because you've added system apps or processes to the MagiskHide list. That's not a good idea... Only add the apps detecting root to the Hide list. Also see "System instabilities" below.

A/B devices (Pixel, etc)
Many users are reporting about bootloops on Pixel and other A/B devices. Often this is caused by having TWRP installed at the same time as installing Magisk. Since the recovery now resides in the boot image, having these two modifications to the same partition may cause issues. If you want to use TWRP, use fastboot to only boot it, don't install:
fastboot boot twrp.img


Custom kernel
If your system bootloops again and you're using a custom kernel, try starting over without installing that kernel. If there's still a bootloop your system might just not be compatible. One possibility is to try finding another custom kernel that is compatible.

Magisk update
If there’s just been a new Magisk release it’s also possible that there might be something with Magisk causing the issue. Just keep calm, restore your device like described above (also see Updating), but first make sure to provide proper logs (see "Asking for help/reporting bugs").

DM-verity and Forced encryption
Another thing to try if your device ends up in a bootloop when flashing Magisk, is to keep dm-verity and force encrypt enabled. By default Magisk might remove these flags from your boot image which on some setups have been reported to cause a bootloop. Keeping these flags is done by running the two following commands in your recovery's terminal before flashing the Magisk zip (or, if you're upgrading from a working version of Magisk, by checking the two options in the Magisk Manager before installing):
echo KEEPVERITY=true>>/data/.magisk
echo KEEPFORCEENCRYPT=true>>/data/.magisk


Module issues
A bootloop might also be because you’ve installed a module that Magic Mounts new files or folders to the root of /system, etc. On some devices this will cause a bootloop. Contact the creator of the module you’re trying to install and let them know… Also see "Module Issues".

Special cases
Some devices need special modifications to the boot image to not bootloop with Magisk. Sony is one of these manufacturers, where you may need to disable RIC.

Magisk not installed

After installing Magisk, if the Manager still reports that Magisk is not installed, check if the Manager has been installed to the external or adoptable storage. This is known to cause all kinds of issues, so make sure that the Manager is installed to the internal storage and check again.

This might also be happen when the Magisk Manager update doesn't go as planned and you end up with two Managers installed or the Manager doesn't actually update. Something that might lead to issues... See "There are two Managers" or "Magisk not installed" for further details.

Some users seems to experience this issue randomly, where Magisk seems to uninstall by itself. See [MagiskIssues | "Randomly loosing root"]] for more details.

System instabilities

If your system suddenly becomes unstable, with reboots and system processes stopping, make sure you haven't added any system apps or processes to the MagiskHide list. Because of the way MagiskHide works, it might kill off some pretty important parts of the running system if this kind of apps/processes are on the list, causing all kinds of havok.

Only add the apps and processes that actually detect root to the MagiskHide list.

Apps are force closing


Apps on the MagiskHide list
If apps on the MagiskHide list are force closing, simply remove them from the list. You should only add the apps and processes that actually detect root. Adding anything else to the list, that doesn't need to be there, may cause instabilities in your system (also see "System instabilities" above) Note: It's not about the number of apps on the list, but which apps are added.

WebView issues
If a bunch of apps suddenly start force closing after installing Magisk, your ROM might have issues with WebView. More precisely with the signatures for Chrome and Google WebView. You can take a logcat when one of the apps crash and see if there's anything about WebView in there. The reason is that MagiskHide sets ro.build.type to "user" and this enables the signature check. Ask your ROM developer to fix the signature error... Meanwhile, you can fix it temporarily by disabling MagiskHide, use the Magisk module MagiskHide Props Config to revert the prop value, or use a boot script to revert the MagiskHide prop change (see "Reverting prop values set by MagiskHide").

It's also possible that removing and reinstalling Chrome stable or Google WebView (or simply installing one of them if it's not already installed) will fix the issue. If nothing else, installing Chrome Beta should work. After that you can go to Developer options -> WebView implementation and select the corresponding implementation.

It might also be possible to use Chromium. There are several Chromium installers available both in the Play Store and on F-Droid.

Other
If it's not an issue with MagiskHide or WebView, grab a logcat from the crash and post it together with lots of details in the support thread (also see "Asking for help/reporting bugs").

Developer options disappeared from settings

If Developer options suddenly disappeared from settings after installing Magisk, it's probably because MagiskHide changes ro.build.type from "userdebug" to "user" (known "safe" prop value). On some devices/ROMs this prop need to be set to "userdebug" to show the Developer options.

You can use the Magisk module MagiskHide Props Config to revert the prop value, use a boot script to revert the MagiskHide prop change, or temporarily disable MagiskHide (also see "Reverting prop values set by MagiskHide")

Or, there's a much better solution... You can ask your ROM developer to add this commit.

Beginning of crash

In the Magisk log you'll sometimes see "--------- beginning of crash". This is perfectly normal and unless you experience issues with Magisk it is nothing to worry about. Since Magisk uses Android's logcat for collecting logs this will appear in the log as soon as there is any kind of crash occuring on your device, regardless if it has anything to do with Magisk or not.

Wifi stopped working

If your Wifi stops working after installing Magisk, try reflashing your kernel.

Magisk isn't working

If you can boot up, but Magisk isn't working as expected (not detecting the Magisk installation, loss of root, etc), there are a few things you can try.


  1. Reboot. Sometimes this helps Magisk mount everything as it should.
  1. Try removing any installed modules to see if it's a faulty module causing issues. If that seems to fix it, install the modules one at a time to find which one causes issues.
  1. If nothing else works, try starting fresh with a new installation.
  1. If you still can't get things working, check here: "Asking for help/reporting bugs".
