Latest Magisk Version: v12.0
Latest Magisk Manager Version: v4.3.1

Hello, welcome to the official Magisk Release / Announcement thread!
Magisk can ROOT your device, along with standard common patches.
It packs with a super powerful Universal Systemless Interface, allowing unlimited potential!

Magisk modifies boot image and add files to /data and /cache
It touches your /system partition only if root installed in /system is detected!

  • 100% fully open source and easy to build!
  • Magic Mount:
    Allow you to do any system (vendor) modification without actually tampering the partitions.
  • MagiskSU: Open Source Root Solution
    Root your device with MagiskSU, based on phh's Superuser, which is based on CM Superuser.
  • Magisk Manager:
    MagiskSU Root Management, Install / Upgrade Magisk in-app,
    Manage, Upgrade, Download, Install Magisk Modules within a few taps.
  • Magisk Hide:
    Hide Magisk from detection, including SafetyNet, which is used in Android Pay, Pokemon GO, Mario Run etc.
  • Resetprop:
    Allow you to do any modifications to system props (build.prop), including read-only props.
    It is also used for tricking the bootloader state, and (for Samsung) the KNOX state
  • Multiple Entry Points:
    Provide several entry points to developers, reliably pausing the boot process before everything is done.
    Include post-fs (cache) mode, which happens even earlier than data is mounted (used to replace Boot Animation etc.)
  • Standard Stuffs:
    Remove dm-verity, forceencrypt; includes a super complete busybox to guarantee consistent behaviour, and can also be toggled to be used universally.

You are not forced to use MagiskSU if you're only aiming other features
However, the only other choice is systemless SuperSU
It will attempt to remove any other root, and install MagiskSU by default

  • Anything that previously modifies /system can be loaded with Magisk. I ported Xposed and ViPER4Android just as an example.
  • Use apps/features that uses Google's SafetyNet detection
  • 100% systemless custom roms (take a look at our 100% Systemless Magisk ROM)
  • (WIP) Universal Multirom for all Magisk supported devices (Proof Of Concept Video)
Installation Instructions
Before Magisk installs anything on your device, it will create a boot image backup in /data/stock_boot_<sha1>.img.gz
If anything goes wrong (e.g. bootloop), you can either use the uninstaller (recommended) or decompress the backup and manually restore your boot image
It should ALWAYS bring your device back to life (suppose you have a custom recovery that can decrypt your /data)

If you're already rooted with MagiskSU or Latest Official Systemless SuperSUIf you're not rooted, or something went wrong and you need a clean start
  • (Recommended) Restore your boot image back to stock (flash uninstaller if Magisk is previously installed)
  • Download the latest Magisk zip file
  • Reboot to a custom recovery
  • If you choose to use SuperSU (only support Android 6.0+), flash SuperSU in systemless mode now
  • Flash Magisk zip
  • Reboot. Update the stub Magisk Manager to the latest from Play Store
Please check here for Magisk Manager Tips!

Latest Magisk
Latest Uninstaller (Support v1+)

Magisk Manager | (direct link)
  • Q: I am losing root randomly!
    A: In some custom roms (known: LineageOS), enabling the Magisk busybox will make root unstable
    If you experience root loss issue, disable busybox in MagiskManager
  • Q: Safety Net fails after enabling MagiskHide
    A: Magisk can only hide Magisk core features, for Magisk modules it depends on what the module does.
    If your ROM itself is not able to pass SafetyNet, then there is nothing Magisk can help.
    Your best bet is 100% stock ROMs, because your phone manufacturer is forced to release a device passing CTS.
  • Q: My device is not supported!
    A: Please open an issue on Github, along with your boot image uploaded. No boot image, no fix.
  • Sony Devices: If you're using stock kernel, it is using Sony's special ELF format.
    Magisk will repack it to standard AOSP format, which requires your device to be unlocked
  • Some of the ASUS devices requires boot image signing, search the forums and sign them yourselves.
To all developer: please check out the WIKI for common issues you might face, for custom rom devs too!
Currently Known Issues (v12.0):
  • Pixel / Pixel XL: WIP
  • Magisk Manager CANNOT be placed in adoptable storage, or superuser will not work
  • MagiskSU does not support multiuser: WIP
  • MagiskSU does not work on Android O preview: WIP
I spent endless hours to create Magisk. If you like my work, feel free to donate.

    - [MagiskHide] Support other logcat am_proc_start patterns
    - [MagiskHide] Change /sys/fs/selinux/enforce(policy) permissions if required
    Samsung devices cannot switch selinux states, if running on permissive custom kernel, the users will stuck at permissive
    If this scenario is detected, change permissions to hide the permissive state, leads to SafetyNet passes
    - [MagiskHide] Add built in prop rules to fake KNOX status
    Samsung apps requiring KNOX status to be 0x0 should now work (Samsung Pay not tested)
    - [MagiskHide] Remove all props, since they cause more issues than they benefit...
    - [MagiskBoot] Add lz4 legacy format support (most linux kernel using lz4 for compression is using this)
    - [MagiskBoot] Fix MTK kernels with MTK headers
  • v11.5/11.6

    - [MagiskSU] Fix read-only partition mounting issues
    - [MagiskSU] Disable -cn option, the option will do nothing, preserved for compatibility
  • v11.1
    - [sepolicy-inject] Add missing messages
    - [magiskhide] Start MagiskHide with scripts
  • v11.0
    - [Magic Mount] Support replacing symlinks.
    Symlinks cannot be a target of a bind mounted, so they are treated the same as new files

    - [MagiskSU] Fixed all issues with su -c "commands" (run commands with root)
    This feature is supposed to only allow one single option, but apparently adb shell su -c "command" doesn't work this way, and plenty of root apps don't follow the rule. The su binary will now consider everything after -c as a part of the command.
    - [MagiskSU] Removed legacy context hack for TiBack, what it currently does is slowing down the invocation
    - [MagiskSU] Preserve the current working directory after invoking su
    Previously phh superuser will change the path to /data/data after obtaining root shell. It will now stay in the same directory where you called su

    - [sepolicy-inject] Support all matching mode for nearly every action (makes pseudo enforced possible)
    - [sepolicy-inject] Fixed an ancient bug that allocated memory isn't reset
    - [uninstaller] Now works as a independent script that can be executed at boot
    Fully support recovery with no /data access, Magisk uninstallation with Magisk Manager

Magisk-v7 is quite a significant update compared to v6. A lot has changed, new features are added, and improved compatibility a lot, especially in selinux issues.

Open Source!
My previous releases has some controversy due to the fact that I included closed source property with unexpected intentions. I had worked hard to create/improve open source tools, so that they can fit my own needs. Magisk is now 100% open source, including the binary it uses.

Brand New Magisk Manager
The Magisk Manager is completely a different application compared to the previous crappy app. It has now packed with features, and it is now part of the core experience of Magisk itself. New features and improvements are still planned, so stay tuned in this application's development!

Repo System, Module Management
We've been putting a lot of effort into constructing this repo system. This change is to make installing Magisk Modules a lot more easier. What I'm aiming is to make Magisk something like Xposed, an interface and a platform for developers to work on. Providing a repo system is a good step towards the goal, as it makes installing new stuffs and receiving updates super simple. I also drastically simplified the Magisk Module template. Right now, I believe anyone with basic knowledge can create their own Magisk Module easily. Changing a few values into a config file should make porting existing mods to Magisk much easier.

Safety Net
My decision to remove root management from Magisk seems to cause some debate. People might wonder why I would remove such feature that made Magisk so popular. Well, I have to emphasize again, Magisk is never meant for bypassing Safety Net. The Xposed and root bypasses are some fun projects that I'm messing with what Magisk is capable of. One of the two main reasons I dropped this feature in Magisk is

1. Xposed is no longer working with Safety Net enabled. I had tried to bypass it with some mounting tricks and process killing, but all of those are not able to fix the issue. Soon suhide is available and it is able to bypass Xposed had made me really frustrated, as I do not want to keep working on a "not complete solution".
2. On the open source side, phh is also developing his own "suhide". phh just released a test build for hiding root (link to his test build), I'm gonna take a look and include it into the Magisk version of phh root.

These two methods are much better than the one I was using. It doesn't need a toggle, it is per app basis, and many more. Also, I'm not creating a root solution, I'm creating an interface that root solutions can rely on. So I decide to give the hiding root "responsibility" to the root solutions, not managed by the interface, Magisk, itself.

Just to let all of you know, one of Magisk Manager's future feature will be a GUI to manage these two root hiding solutions. It will need some time to develop, and I also wanted to do some things in the core Magisk side to add this support natively. So please don't be pissed that I dropped the whole root management thing. It is for a bigger plan

Due to a bug in the template zip, there will be issues flashing the zip files if the path has spaces.
This commit in magisk-module-template should fix the issue.
All repos online is updated with this fix, developers please include this patch into your modules.

2016.10.19 Magisk v8
This release is aimed for bug fixes, and most importantly the ability to hide itself from Safety Net's detection.

Template Cache Module Fix
Due to a bug in the template script, if your module is a cache module, your scripts might not be executed correctly, also flashing in Magisk Manager will cause the UI to break.
This particular commit is the fix, only cache modules are needed to be updated, other modules are working fine.

Search Bar in Download Section
Magisk Manager 2.1 brings search bar to the "Downloads Section", so that it's easier to find a module once the list gets too long.

SuperSU Integration
In the previous release (v7), I decided to automatically convert SuperSU into a Magisk module while installing Magisk. In this release (v8), I make Magisk 100% compatible with SuperSU out of box, not needed to modify how SuperSU work in anyway. For v8 and future releases, Magisk will detect SuperSU patched boot image, and only add the required additional patches to the boot image.
Also, I created further integration for Magisk and SuperSU: Magisk will create a script placed in /data/ when SuperSU detected. What this means is that the next time you upgrade SuperSU by flashing SuperSU zip in custom recovery, Magisk will automatically be injected. You can also apply OTA updates with FlashFire, and enable SuperSU injection, which will also inject Magisk on-the-go!

For users that was using v7 with SuperSU along with the Helper Module, please manually restore your boot image (should be stored in /data/stock_boot.img), and flash the latest SuperSU, then flash Magisk-v8.

Magisk Hide
This feature should've been released a few weeks ago, but university is killing me lately; overwhelming schoolwork prevents me to finalize the tool, so please pardon my absence and lack of support. But it's still better late than nothing .
In the weeks I have been inactive, Safety Net got a couple updates, each makes bypassing more of an hassle. Magisk v8 introduce "Magisk Hide", the tool to properly hide Magisk, preventing Magisk to break Safety Net features. What it can do is hide all Magisk modules' files and mounts from target processes (e.g. Safety Net), including Magisk compatible phh root maintained by myself.
It cannot hide SuperSU, it cannot hide Xposed. If you want to hide any of them, please use suhide developed by Chainfire.

It should not cause issues as I have been testing quite some while, but if you replace some files with Magisk (known: /system/etc/customize/ACC/default.xml), Google Play Service will constantly crash. Due to this fact, this feature is not enabled by default. You have to manually enable it in the settings of Magisk Manager v2.1 after you upgraded to Magisk v8, and reboot to apply the settings.
Right now, you can manage your own hide list with ways similar to suhide, no GUI:
(All commands should be run in a root shell)
# Show current list

# Add new process (the package name should work fine)
/magisk/.core/magiskhide/add <process name or package name>

# Remove a process (might need a reboot to make an effect)
/magisk/.core/magiskhide/rm <process name or package name>
The process (Safety Net) will always automatically be added to the list if Magisk Hide is enabled, so if you just want to bypass Safety Net, just enable in Magisk Manager and you're good to go.

Safety Net - The Already Lost Cat-And-Mouse Game
Keep in mind, in the latest update of Safety Net that just happened in a few hours, Google seems to step up the game, and it might got to the point that no modifications are allowed, and might be impossible to bypass.
Currently on my HTC 10, no matter what I did to the boot image, even just a repack of 100% stock boot image, Safety Net will not pass under any circumstances. On the other hand, my Nexus 9 running stock Nougat seems bypass without issues, with root and modules all enabled and working fine. The boot verification might vary from one OEM to another, HTC's implementation might just be one of the first included into Safety Net, but eventually all major OEMs' method will be included, and at that time I think any Android "mod", including custom kernels, will pretty much break Safety Net. These verification should be coded deep into the bootloader, which is not that easy to crack. So the conclusion is that I will not spend that much time bypassing Safety Net in the future.

Magisk MultiROM - POC

I spend some time playing with the possibility of Universal MultiROM by only using Magisk.
Surprisingly, it is not that difficult at all! Here is a small POC video demonstrating my HTC 10 dual booting stock rom and CM 13.

No other dependency is required (e.g. modified TWRP recovery, kext kernel patch etc.). You only need Magisk injected into the boot image, and along with proper settings, by swapping out the boot image, you can load any rom systemless-ly.
What this means is that all Magisk supported device can enjoy MultiROM features! What a great news for flashaholics LOL.

NOTE! The process showed in this video in far from what it will be eventually. I will make the process nice and smooth

2016.11.14 Magisk v9
This release comes with significant updates and changes, doing adjustments to pave the road for the next major update v10: the update with Multirom support!
Please spend some time reading this lengthy release note, the most important information are included in quotes, or bolded and colored in RED.
Also, many other fixes not mentioned here are listed in the changelog.

The End of Cache (post-fs) Modules
This shall be the biggest change for this update. One of Magisk's cool feature is that it can mount files before data and build.prop is loaded (post-fs). Most modules only uses this advantage to modify read-only props (e.g. DPI, fake device model etc.) without modifying build.prop, however with a new tool included in this release (will be introduced in the next section), dealing things in post-fs is not needed anymore.
Instead of having both "Cache Modules" and "Normal Modules" at the same time, confusing both developers and users, creating complexity in module management, the decision is made that "Cache Modules" are no longer supported after this update.
How about some features that require mounting in post-fs mode (known: Changing Boot Animation)? No worries, post-fs mode is still there (as Multirom will depend on this), I only removed the interface for modules.

Magisk no longer let you install cache modules, you have to manually add the files you want to replace, which is actually super easy.
You can place your new files into the corresponding location under /cache/magisk_mount, Magisk will automagiskally manage selinux contexts, permissions and the mounting for you.
For example, you want to replace /system/media/, copy your new boot animation zip to /cache/magisk_mount/system/media/ with any root explorer, Magisk will mount your files in the next reboot.

Magisk v9 will remove all installed cache modules under /cache/magisk, which is the previous path where cache modules locate.
Further more, to push developers to upgrade their cache modules, the latest Magisk Manager (v2.5) will filter out cache modules, which means cache modules available in the Magisk repo are NOT shown under the "Download" section in Magisk Manager.
Cache Module developers please refer to the following instructions to update your current module:
  1. Take a look at the changes in this commit (if you're famlier with git, you can just cherry pick this commit, and deal with some minor merge conflicts)
  2. Check the "resetprop" section to understand how to change props without using a cache module, and update your modules accordingly. For example, if you want to replace the build.prop, you no longer need to enable "automount", or bind mount the file manually in your script, as nothing will load it again.; instead, you should enable post-fs-data script, and read your new build.prop file with proper commands. If you want to change certain prop values, just switch from post-fs script to post-fs-data script, and instead of calling "setprop", please call "/data/magisk/resetprop" to set your props.
  3. Remember to remove the "cacheModule" entry or set to false in the module.prop file, or else your module will never show up in the Magisk Download section in the Magisk Manager!

New Badass Tool - resetprop
To be honest, this tool itself deserves a new thread on XDA, as it is super powerful and super cool.
"resetprop", originally named "xsetprop", was initially developed by @nkk71 to bypass the crazy tough detections for Safety Net. Developers found method to bypass the check by modifying the kernel source code, which served the need but the solution is far from perfect as it requires the source code to be available and kernel compiling.
The tool was originally made to directly modify the system prop database. With seeing the potential of this tool, I contacted @nkk71 and start collaborating together, which brings the original simple tool into a full-fledged, all-in-one prop management tool.
Here are some technical details:
System props are handled by "init", a binary located in the ramdisk which starts right after kernel is loaded. "props" are supposed to only have a single writer, and multiple reader, which means only the process "init" has the full control to the prop database. We modify the props (by calling setprop) through an interface called property_service, which will pass the request to init; property_service also handles the triggering of "events" that should be triggered by a prop change. What read-only props means is that property_service will block all requests for modifying props starting with "ro.", as those props are not allowed to be changed once set. To overcome this difficulty, we can mimic how init behaves by directly modifying the trie structured database. However we will not be able to trigger events, as we completely skipped the property_service part. This might be ideal for SN bypasses, but not applicable for Magisk, as I want to load any prop, which should trigger some events to make some changes. So we went a step further and added a feature to "delete" a system prop! As a result, by directly deleting the prop entry in the database, then send a request to property_service, property_service will accept the request and trigger events if needed.


The new tool - resetprop can modify/delete any system prop, including read-only props (prop names starting with "ro.")
You can also read a whole build.prop, overwriting all existing props. The binary will be installed to /data/magisk/resetprop.
Here are some examples for cache module developers to adapt to the new changes:

# Set any prop (with trigger)
/data/magisk/resetprop ro.sf.lcd_density 480
# Set any prop (without trigger)
/data/magisk/resetprop -n ro.crypto.state encrypted
# Delete any prop
/data/magisk/resetprop --delete magisk.version
# Read props from a prop file
/data/magisk/resetprop --file /magisk/somemod/new_build.prop

The tool is originally built with AOSP source, I spent some time to make it much more portable.
Here is the link to the NDK-buildable source of the resetprop used in Magisk:

Magisk Hide - Greatly Improved
Another update to pass SN, please grab it before it expires lol
People started to panic when Google device to check boot loader / boot-verity etc. As stated in the previous section, resetprop fixes the issue easily with setting all detecting props to the valid values. However, more detection has been added. One of those is that simply adding Magisk directories into PATH will break Safety Net. Not sure if I should be glad because the word "magisk" is now officially on the tech giant's blacklist......
So in order to hide root (here I'm only referring Magisk phh superuser, as SuperSU users shall always rely on CF's suhide, not MagiskHide), I had to change the way things works.

For the new changes that are required to NOT modify PATH, the phh's superuser has to be upgraded.
Please make sure your phh superuser is upgraded to r266-2 (or any version higher).
Older version will NOT work with Magisk v9, please upgrade phh's su before upgrading.

Also, along with the new Magisk Manager v2.5, we finally had an GUI to add/remove apps from the MagiskHide list!

I added into the main Magisk repo, you can call the script and it will guide you with help messages.
Custom version names are supported, both in Magisk and Magisk Manager (if using custom name, update will disable)
So feel free to clone the repo and develop Magisk yourself! Pull requests are appreciated!
For Magisk Manager, you can provide translations for the app, just translate the strings, create a pull request, and I'll merge it into the main app, many thanks!

Those Pixels
I stated before that the new Google Pixel devices are using a complete different partition structure, as the ramdisk is now stored along with the system partition, and a kernel modification is inevitable.
Without much surprise, our mighty developer Chainfire had released a systemless root for Pixel devices. What it does in a nutshell is bringing back the ramdisk to the boot image, and still do modifications in the ramdisk (rootfs). However it still requires 1. custom init binary 2. binary patch directly to the kernel. If I decide to use the provided closed source solution, it shall not be difficult to port Magisk to the Pixels and start all the systemless craziness, but still I need an device to test and debug. In addition, I would love to see if I can create an open source tool to achieve similar results to make Pixel (which means maybe all future devices) running Magisk.
But the huge issue is: I live in Taiwan, and there is no sign that the Pixels will be available for purchase here, well at least not possible in 2016.
I could ask my buddy studying in the US to bring me one when he comes back at the Christmas vacations (which is still quite some time from now, but still better late than nothing.....), however the problem is that Pixel XLs (the model I prefer) are currently out of stock on the online Google Store, and I will never know if ordering now will make the package show up in my friend's place in time before he comes back to Taiwan.

If anyone seeing this post has access/can purchase brand new Pixel XLs (anywhere should be OK), and possible to deliver them to Taiwan in a reasonable time and a reasonable shipping fee, please contact me and I'll be very happy.
Lastly, I just bought my new HTC 10 within a year. I'm just an university student, the money I earn from tuition could afford me the super expensive Pixel device, but any additional donation to support my open source development is highly appreciated . I'd be really happy that many people love my work!

Here are some news....

Lack of Support
School have been super busy lately (getting the last metro to home nearly every day...), I have little if any time to spend on Android development. Another big factor is that I'm still waiting for my laptop to be repaired.
Sorry for all the private messages sending to my inbox, I've got way too many PMs that I'm not in the mood to read through dozens and dozens of them, since a large fraction of them are simply just asking for instructions for installing Magisk on their device.
I prefer REAL issues to be opened on Github, as I check them from time to time, and I can keep track of which are not yet resolved.

Build Friendly
I added build script for Unix-like systems (Linux and macOS) and also for Windows. I tested on all three platforms and all of them are working as expected. For people interested in the latest feature added to Magisk but not included into an official release yet, feel free to build it yourself. I automated the process that even people with no experience in NDK or scripting can build it easily.
Also for people willing to report bugs, please test Magisk built against the latest commit before opening issues on Github, thanks a lot!

Magisk Module Repo?
It has been a while since I last updated the Magisk Module Repo. I know there are a few requests for adding their own modules to the repo. I'm gonna change the way for requests to be handled from the current "posting in a request thread on XDA", to most likely handled through Github. When the new way for requests is decided, I'll add the current requests at once, and close the current thread.
I really appreciate every person who is interested in making a Magisk Module and willing to share it with others, once the new method is decided, the requests should be addressed in a timely manner.

Multirom? Updates?
I've spend my extremely limited free time to fix current Magisk issues, and so far (the latest commit on Github) it has improved a lot compared with the current v9 release.
I haven't really spend much time in the multirom feature, however I found an interesting open source project: DualBootPatcher.
It exists for quite a while, and it is very impressive just like the Multirom Tasssadar created. I haven't looked into how DualBootPatcher works, so I'm not sure if it is using similar tactics method that I switch between systems in a super simple way through Magisk.

2017.1.2 Magisk V10
Happy New Year! What is a better way to celebrate 2017 than a Magisk update
Another massive update!

Official Icon
Instead of using the picture grabbed online, the official Icon for Magisk is now live!

Magisk Hide Back On Stage
This is the most awaited fix, isn't it?
The issue of losing root is haunting since day 1 of the release of Magisk Hide, although it can be temporary recovered with a reboot, it is still quite annoying. I spend a lot of time trying to identify the reason, and soon found out that the issue is caused by MagiskHide reacting "too fast". Most processes starts from Zygote, and it requires a small period of time to isolate the mount namespace apart from Zygote. When MagiskHide reacts too quickly, it will unmount all mounts in the Zygote namespace, which literally means that all processes will lose the mounts (including root).
After adding checks and retries before switching namespaces, it leads to another issue: MagiskHide reacting "too slow". When critical files like framework is Magic Mounted, and the unmounting doesn't happen in time, it will break the SafetyNet checking process (Google Play Service FC), and can never recover until a reboot (or full restart of Google Play Service). I added tons of safety precautions (I won't go into the details here, it will be another few hundred of words), and I can "almost" eliminate all possible breakages.
Due to the fact that Magisk Hide DOES NOT hijack app_process (Zygote), it can only react passively, so there is a limitation to the effectiveness.
The best practice is to NOT add a lot of apps in the blacklist of MagiskHide (managed in Magisk Manager), so that the MagiskHide daemon has the time to react.

Personally I only hide SafetyNet (the preset), and it passes all excessive tests without any issue. However my tester still managed to break it a few times when adding 6 additional apps, and having 10+ accounts syncing at the background all the time. So I guess it is good for most users lol

Magic Mount With No Limits
I'm glad to announce that starting from this update, Magic Mount can do ANYTHING! Thanks to the new mirror implementation and some workarounds in the algorithm, it can now handle adding files to /system root (and /vendor root if separate partition). Also thanks to the new MagiskHide, all mounting combinations can pass SafetyNet!

Magisk Powered Custom ROM: One Click to Custom ROM, Another Click You're Back to Stock
I am a member of an HTC custom ROM developer team - Team Venom, and without too much effort, The world's first Magisk Powered Custom ROM was born!
The advantage over traditional full packaged custom rom is that we ROM developers no longer need to port carrier features (Wi-Fi calling, VOLTE etc.) to our ROMs. Users can install Magisk on their stock devices, load the Custom ROM module, reboot and BOOM all done, along with 100% fully working carrier features. Also, it is just cool to load a custom ROM fully systemless, isn't it!
Developers in the HTC 10 community soon realized the "power of Magisk", and currently trying to push out more and more Magisk Custom ROM Modules.
I hope all developers feel the excitement, and port all stock modified custom ROM to be implemented with Magisk!
For ROM developers interested, please check the link and download the zip to get an idea how to create your own Magisk Custom ROM Module!

Magisk Can Now Root Your Device
I decided to fork the phh Superuser and start doing modifications. From Magisk v10 and after, Magisk will root your device with the bundled root if
a. No root installed b. Root that isn't Systemless SuperSU or older Magisk phh versions installed
Right now you still have to install the phh Superuser application, however the root management should move to Magisk Manager soon, please stay tuned.
Currently it is nearly the same as official phh root with only a few tweaks, but I might add more in the future.

Magisk Manager Now On Play Store
It seems that some already found out that Magisk Manager is now available on Play Store! All future updates will be pushed through Play Store.
Download links will still be posted here, since there are still places where Play Store isn't available.

Documentations Updated, Module Template Updated, New Repo Requests
The documentations here on XDA is pretty outdated, I updated them with more info to assist developers and users to create their own modules.
Module template is updated for an addition option to load a prop file.
Repo requests are also updated, please check out the new instructions!

Sorry guys, in v10 (and the v10.1 if you're fast), when updating within the Magisk Manager, my scripts didn't handle the phh upgrading correctly.

For those got stuck with no root, please flash the latest phh zip downloaded in this thread in custom recovery (or Magisk Manager, because it is the only app that have root access).

Sorry for the inconvenience, please forgive me lol, I'm only one man!

Magisk Manager v3.1

I'm still dealing with my finals (got an exam tomorrow, and 3 more projects to do......), but the online repo is no longer accessible on Magisk Manager, which forces me to push out an update.
Apart from that critical bug fix, it also comes with a lot of updates and improvements, please check the changelog for further info.

Please update your Magisk Manager from Play Store. The direct link is also updated with the new v3.1 version
