Welcome to the official Magisk Release / Announcement thread!
Installing Magisk will give you ROOT, a super powerful Systemless Interface, Magisk Modules support, and hide from tons of integrity tests like SafetyNet!
Magisk does NOT have a website. Do NOT download Magisk from unofficial sites.

100% open source and easy to build on all Google supported platforms.
Modify system (vendor) without tampering the partitions.
Unleash your device's root access.
Hide Magisk from detections: Google SafetyNet, enterprise / bank system integrity checks, game tamper checks.
Modify or delete any system properties, including read-only props.
Android 4.2+: MagiskSU and Magisk Modules Only (*1)
Android 4.4+: All features available (*2)
Android 6.0+: MagiskHide guaranteed support (*3)
Android 7.0+: MagiskHide full protection
Android 9.0+: Magisk Manager full hide capability
Resetprop and MagiskHide is not possible to be supported.
Pre 6.0 kernels are very likely to have no mount ns procfs support, which is required for MagiskHide to work properly. This Linux kernel feature is only required to be added in Android 6.0.
If your kernel lacks this feature, you can build (or ask your custom kernel dev) with some additional patches. The relevant patches are: set CONFIG_NAMESPACES=y in defconfig, and apply this patch. More info: Namespace file descriptors (2010 original article)

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.
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.
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.
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/custom_ramdisk_patch.sh 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.
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 com.google.android.gms.unstable (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.
The attachment is a screenshot about where to enable Magisk Hide in the app
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/bootanimation.zip, copy your new boot animation zip to /cache/magisk_mount/system/media/bootanimation.zip 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:
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)
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.
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: https://github.com/topjohnwu/resetprop
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 build.sh 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!
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!
