Magic v11 installation question

Hi, do i need install systemless SuperSU always in twrp before install magisk v11 if I want use new MagiskSU instead??
If I try install Magisk v11 with superSU uninstalled and phone unrooted TWRP give me error and installation fails and if I install superSU and after Magisk v11, Magisk manager say system is using SuperSU instead MagiskSU. How do I install Magisk with MagiskSU??
I have Samsung Galaxy S4 with optimized LineageOS 14.1

Read the pinned Magisk thread...
Unroot again using unSu by osm0sis (Google) before flashing magisk

Installation Instructions
If you're already rooted with MagiskSU, Magisk phh's superuser (not original), or Official Systemless SuperSU
Install/upgrade Magisk Manager from Play Store
Install/upgrade Magisk as prompted in the application
Reboot and you're done!!
If you're not rooted, or something went wrong and you need a clean start
(Recommended) Restore your boot image back to stock
Download the latest Magisk zip file
If you choose to use SuperSU (only support Android 6.0+), first flash SuperSU in systemless mode
Flash Magisk zip
Reboot, and update the stub Magisk Manager to the latest from Play Store

You need to FULLY unflash superSU using the zip that the other person told you to google.

Ok I will try unflash with the zip, I was using unroot inside superSU menu but installation instructions dont say nothing about the unflash with an extrenal script

Yeah that button doesn't work for systemless superSU. It doesn't roll back your boot.IMG like it should.
Worst case scenario, flash the stock boot.img and then flash magisk.

Thanks guys, I installed Magisk v11.1 with MagiskSU working, Magisk Hide enabled but I have CTS mismatch error now in Safetynet test. I guess I cant do nothing about this error. Optimized LineageOS 14.1 and Samsung Galaxy S4
EDIT: Finally I passed the Safetynet test (no CTS mismatch error) disabling ADB interface in developer options. Thanks for Magisk, amazing.

By disabling ADB interface, do you mean the USB debugging part? for some reason I am still getting Safetynet error.

Thanks for this hint; got my build "passed" now appreciate it

What settings are you guys using in Magisk? I have disabled BusyBox, enabled Magisk Hide and systemless hosts. Superuser options are Access to "Apps and ADB" and Automatic Response set to prompt

I'm still having an issue installing Magisk on my phone with RAMROM V10. It gives me an ERROR 1.
It has been suggested that I should re-flash my boot.img with TWRP following the instruction:
Place your BOOT.img on your sdcard
Reboot into TWRP recovery
Tap "Install"
In the bottom right corner tap "Install Image"
Select your BOOT.img
Select the Boot Partition, then swipe to confirm Flash
However, when I follow the step, my TWRP cannot seem to find BOOT.IMG in my SD Card (I know it is there). What did I do wrong? Can anyone help?

i think the .img thingy is only for twrp.img files. You have to use another method to place your boot image like. -> make a backup of only your boot image via twrp backup function. Then duplicate that backup folder of twrp containing only the newly just regernated files, in the twrp folder. Then replace the su-modified boot file there with your original boot file, you obviously have to rename your boot image to fit the right name. (eg. with the logo image -> logo.bin changes to logo.emmc.win -> etc;.) Then use the twrp restore function to restore your "original" boot logo.
Hierarchy folder view would be like:
TWRP->folder 1 (original folder, in case something goes wrong)-> boot file and others
->folder 2 (our modified folder)-> files

FIY: Flashing regular boot.img files works just fine with "Install Image" in TWRP (of course, YMMV, depending on your device).

Magisk install bootloop

I installed magisk through flashing zip in twrp (tried v16, v16.6 and v16.7 beta) on my moto x4 (stock boot.img, Android 8.0), installation works but when I reboot to system I get stuck in a bootloop. I installed "mm" module and it shows the installed module, so I guess magisk is installed correctly. I tried looking for a magisk log in /cache but it is empty, and since it does not even get to the "normal" stage of a system boot I also got no adb logs. I also tried patching the stock boot.img with magisk manager and flashing this, but that also results in a bootloop. Really not sure what I'm doing wrong, I checked tutorials/videos (also specifically for my device) and it's rather straight forward, just flash the zip and done. Any help would be appreciated.

Android 4.2 and 4.4 Mediatek bootloop after installing Magisk 18.1

Hello everybody.
I've read that 18.1 supports 4.2+ so I've tried to install in two MTK6589T devices I've. One running 4.2, the other running 4.4
CMW/TWRP gave an error mounting system, so I mounted system manually and it started flashing. Firstly it detected old root installed and disabled the old root. But when it tried to find the boot, installation was aborted because installator claims cannot find the boot on both phones.
Then I though, okay, lets reboot back to android, I will try to install a few days later, maybe its buggy now, but both phones cannot boot.
I can easily fix them by flashing rom again I guess, but I would like to know where's the issue and also post it for more people could face the same problem.
Any idea where's the problem/how to fix without rom reflashing? I've tried magisk uninstaller but after mounting system in recovery it is also giving error.
Thanks
UPDATE: For now, if no other solution is found, bootloop can be bypassed by dirty installing the rom again. But it has to be an easier workaround...
We know now that the problem is caused because of two factors merging:
1- Using Magisk.zip installer through custom recovery
2-In the case that the custom recovery CMW/TWRP installed in the phone is very old (for instance, CMW automade for MTK6589X or TWRP 2.5.0).
While installing, Magisk tries to send commands to the custom recovery that cant be understood by it, leaving the installation incomplete after some modifications in /system (read below recovery log).
Acording to the recovery, it seems that Magisk did some modifications without running correctly survival script - Adding addon.d survival script ("Unrecognized option '-Xnodex2oat'") and .zip installer is not designed to revert actions in this case.
Also, Magisk couldn't reach the boot modification step, so boot is not damaged, therefore workarounds for restoring boot won't work.
Using Magisk Unistaller.zip is also not possible as the uninstaller is mainly designed for boot backup restoration, and again, this is not the case.
Currently needed: Find what's wrong in system due to the incomplete Magisk installation to revert it back to the original state (before faulty magisk.zip installation).

I' also having the same problem. My Samsung J2 Prime stuck at logo after updating to 18.1. Any tips on how to fix it without resetting my phone? Thanks.
Update: Bootloop fixed. I used TWRP to restore boot image. I then update Magisk by flashing zip file from TWRP. Everything went back to normal. Hope this help.

If you have a backup of your boot image, you can just restore it using TWRP. But in case that you have no backup of boot image, you can try to get boot image from the internet and restoring using it. In my case, this is what I did.
1. Go to TWRP and then make backup of boot image of the faulty phone*. (Folder 1)
2. I used another J2 prime to create a boot image backup. (Folder 2)
3. Once that is done, copy and replace the files inside the Folder 2 into Folder 1.
4. Reboot to TWRP again then use that to restore the boot image on my stuck J2.
Tips: make backup in SD card so you can easily swap it in between the bad and good phone.
*This is to create a folder of the backup file. I did tried to directly copy and paste the backup boot image file from another good phone but TWRP didn't detect it. So this is the workaround that I come with. And it worked for me.

Thanks for your answer but I doubt your case is mine. Your device is much newer than mine and according to your comment, you've sucesfully installed previous version of Magisk without issues. This is not a problem while updating, as Magisk v. earlier than 18.1 was not compatible with android 4.2+. I think Magisk is not compatible with MT6589T even if they run 4.2 or 4.4.
I think that it cannot be a boot problem as TWRP/CWM displayed msg 'Boot cannot be found' while installing Magisk, so that I don't think boot was replaced or modified in any ways. Moreover, the bootloop is not in the boot loading, as phone can pass boot image without any problem, but it is stuck in android loading image. I'm thinking in some script or root modification that Magisk did before trying to unpack the boot, however I'm not that deep into the Magisk install to find the proper workaround.
I can restore boot backup and also I can take boot file from the original rom and flash, because in Mediatek-based devices, boot.img is inside de zip, but I dont think it will solve the problem. Anyhow I'll get back ASAP with the answer.
Any more ideas??

Nothing, boot/uboot restoration or flashing again just the boot won't fix the problem, so it's something that Magisk installator touch in /system or /data I guess, but what?

@trol_sg I'm gonna guess it's got to do with the absolutely ancient TWRP you're using. It just can't handle everything that the Magisk installation script is trying to do...
Your best bet (if Magisk will work at all on your device) is to patch the boot image with the Magisk Manager and then flash the patched image manually. There are new and shiny installation instructions available here: https://topjohnwu.github.io/Magisk/

Thank you so much for your answer. So it's the recovery, but can't find newer ones, sadly. Too old phones I know, but just curious if I could make Magisk working on them, lol.
I was going into the boot modification manually right now, but in order to patch the boot I need manager installed first, and phone couldn't boot so I did dirty flash of the rom to be able to boot into it again.
Lets see what happens then. I'll be right back.
Anyhow, this is not a solution to fix the problem of bootloop that I am requesting help in case someone could face the same and did not make a backup of the phone and didn't want to make dirty re-flash. Any idea?
Update: After I did dirty flash of the rom, and now Jiayu g3s android 4.4 booted.

UPDATE: So, after patching manually boot and installing (using restore in TWRP 2.5 as image flash is not yet implemented AFAIK), phone booted and yes Magisk is working.
Magisk installation .zip through a very old recovery is making the bootloop. So that, a thing learnt now.
But, for other people facing this bootloop, can we do a research to find what magisk.zip did to the phones to leave them in bootloop? Maybe we can revert without rom flashing easily if we knew what's the issue...
Thanks in advance!

Doing a bit more tests I found that magisk.zip did something in /system so that it is left in bootloop, but still no idea why/whats causing that...

There are delay complete boot like 4 5 second in j7 prime. I didn't love this version

any more help?? up!!

- installed magisk uninstall
- rebooted in fastboot/bootloader mode
- flashed original boot.img extracted from stock image zip file ("fastboot flash boot boot.img")
- rebooted to TWRP
- installed magisk 17.0 zip file
- rebooted to system, all OK!
Only problem is that I lost previous magisk configuration, but it's a snap to reconfigure it!

Hello, thanks
This method won't work in my case as in the step:
- installed magisk uninstall = gives error
Note 5 is much newer phone with a recent recovery TWRP that allows all Magisk.zips commands, but unluckyly not this case.
Also, this method is for wrong boot installation/damaged boot. In my case what Magisk damage is /system, not boot.
I wish it could be boot, because that is very easy to fix (flashing through fastboot/SP Flash tools in the case of MTK, recovering boot twrp "backup" even if you didn't make backup...) as you mentioned.
Hope someone have a great idea to revert system to origin, then we could post the solution for those who would like to install Magisk in 4.2+ old phones, and instead of doing boot flash manually, they try to flash magisk.zip and they got bootloop.

Main post updated with all thread information. Up!

The only part of the Magisk installation that actually touches /system is if it installs the addon.d survival script. The log you posted earlier shows that it's trying to do this, for some reason, and failiing. I'd start looking there...

Unable to install Magisk - getting "Unable to repack boot image!" error

Good evening lads. I've been having problems installing Magisk.
I've successfully rooted my device (a Samsung J5 2016) and installed Magisk Manager. From there, I selected "Install" and after the confirmation that I want to install Magisk v20.4(204000) I choose "Direct Install" , which is also the recommended option but get an installation error.
Here's my log:
Code:
- Target image: /dev/block/mmcblk0p16
- Device platform: armeabi-v7a
- Unpacking boot image
- Checking ramdisk status
- Stock boot image detected
- Patching ramdisk
- Repacking boot image
! Unable to repack boot image!
! Installation failed
I'm very noob at this and barely have any idea with what I'm doing, so I'm asking you, what can I do? I checked other threads but their logs was very different.
I've never had any other problem with other root apps (Lucky Patcher, Titanium Backup, Root checker etc.) and all I want to do is hide my root so I can use the Nintendo Switch app, lol.
Thanks in advance for your help.

The usual answer is, into Recovery and flash Magisk Uninstaller, then install the Magisk file in Recovery.
I can't give any guarantees, but that always used to be the way to go, if Magisk did not install with Direct Install option.
Like I say, no guarantees.
Should have said, make a Recovery Backup before attempting.
Second thoughts, another poster has just reported a problem installing 20.4 in TWRP, so maybe it's not such a good idea after all.
I don't advise.
Sorry for wrong advice.

if anyone is having trouble while installing magisk I have come up with solutions.​
if you have installed magisk but it never detects as it is installed the following would be solutions i have found for my self​
install magisk that is older than the one you are going to install in recovery with sideload for eg. to install magisk 25.00 from the recovery you need to install magisk 24.1 apk before that without shutting down your phone.​
the second step you need to do is you have to side-load the latest version after you have installed the older version from the recovery​
that is it simple as it is​

Magisk v21 on android 11: bootloop at bootloader when flashing magisk patched img

I've been waited for Magisk v21 released by John Wu this morning, but I ran into some problems
What I've done
- download stock image file from Google official site
- follow the instruction given by John Wu at GitHub wiki
- run command
Code:
adb shell magisk --remove-modules
- when i flash the patched boot.img file, it stuck on the *G logo* with progress bar under it.
- After a certain period of time, it comes back to bootloader with a prompt saying: "no valid slot to boot".
What i've tried:
- redo all processes, no working
- switch active slot to both a & b, none working
- re-patch the stock boot.img file use different Magisk Manager version. The ones i tried: v8.0.0-Beta(offers Magisk v21), v8.0.0-Stable(offers Magisk v20.4), Canary version (offers Magisk Canary who claims to support android 11)
- change the command
HTML:
fastboot flash boot ***.img
to
HTML:
fastboot flash boot_a ***.img
&
HTML:
fastboot flash boot_b ***.img
then run
HTML:
fastboot reboot
. same result as said before
Basic info:
- Device: Pixel 3 (blueline), android 11 (build number RP1A.200720.009), latest android security update & Google play system update.
- Magisk: Magisk Manager v8.0.0 (released hours ago), Magisk v21 is suppose to be installed

Is patched boot.img filesize ~32 or ~64mb?

I ran into the same problem. My phone is a Pixel 2 XL running Android 11. However, I was not patient enough to wait for the "no valid slot to boot" message. After waiting for 5-10 minutes, I did a factory reset.
I followed the installation instruction that were posted by John Wu.. (As a new user, I am not allowed to post an outside link)
The displayed Magisk installation messages do not suggest a problem:
- Device platform: arm64-v8a
- Copying image to cache
- Unpacking boot image
- Checking ram disk status
- Stock boot image detected
- Patching ram disk
- Repacking boot image
***************************
Output file is written to
/storage/emulated/0/Download/magisk_patched.img
***************************
- All Done!
The boot.img and magisk_patched.img files have both a file size of 41943040 bytes. This is a different from previous Magisk version. For instance, with Magisk 20.4 and Android 10, the file sizes of boot.img and magisk_patched.img were 41943040 and 25747456, respectively. Thus, the patched file was smaller than the original.

the stock & patched boot.img are both 65535KB large, which is weird and also mentioned by @red stapler

The boot.img and magisk_patched.img files have both a file size of 41943040 bytes. This is a different from previous Magisk version. For instance, with Magisk 20.4 and Android 10, the file sizes of boot.img and magisk_patched.img were 41943040 and 25747456, respectively. Thus, the patched file was smaller than the original.

Seems like we're in the same boat here lol, is this enough proof for a legit bug issue to John?

the stock & patched boot.img are both 65535KB large, which is weird and also mentioned by @red stapler

The patched boot image is supposed to be the same size as the original now.
From the v21 changelog:
[MagiskBoot] Pad boot images to original size with zeros

Glad to hear, hope this indicates patch is successfully done?

Why not:
adb reboot bootloader
fastboot boot twrp-xxxx.img
adb push magisk-xxxx.zip /tmp
adb shell twrp install /tmp/magisk-xxxx.zip
adb reboot system
Let the magisk zip update script figure everything out...
Its what i do on Pixel 2 XL, works every time...10/11

So far, what we've seen that is causing issues with Android 11 and Magisk is usually either having incompatible modules installed (the brand new Safe Mode should take care of that, see the FAQ for details), or having TWRP installed to your device (it'll cause a conflict and the device won't boot, install the stock recovery and only use TWRP booted).

I forgot to mention that I didn't install or use a custom recovery, such as TWRP. Using the stock recovery.

I forgot to mention that i run this command before install magisk patched boot.img
Code:
adb pm shell magisk --remove-modules
I didn't have TWRP installed on my device, don't seem to have TWRP for Pixel 3 on android 11.

Just tried boot into TWRP img, failed. It just says:
Code:
FAILED (remote: 'Error verifying the received boot.img: Invalid Parameter')
Googled it & find out TWRP's a deprecated/no longer recommended way to install Magisk. And according to John Wu's installation instruction, it is no longer supported in modern models.
Due to this reason, we no longer recommend installing Magisk through custom recoveries on modern devices.

BTW he also said the "patch image" method is guaranteed to work 100% lol, should we let him know hhh
--------------------
edit:
Just find out Pixel 3 (blueline) has **NO** official support of TWRP v3.4+, but Pixel 3 XL (crosshatch) has it. How ironic.
and I wonder if TWRP v3.4+ support android 11?

Hmmm, disappointing
Ive literally tried the image patch method once, a lot of faffing about, I always use the TWRP method, easy peasy at least for older device
....we no longer recommend installing Magisk through custom recoveries on modern devices. The custom recovery installation method exists mostly for legacy support.
Download the Magisk installer zip
Reboot to custom recovery
Flash the zip and reboot
Check whether Magisk Manager is installed. If it isn’t installed automatically, manually install the APK.

Guess ill be happy to remain a legacy device user

This saved my day:
Code:
fastboot --set-active=b
You might need to use "a" instead.
In my case the kernel was loaded and started and Android startup was hanging.
I guess we have to wait until this is fixed.
Edit: Pixel 3a XL, latest Android 11

Hey all, i have a pixel 2 XL and I'm also stuck in bootloop. However i can't find how to do a factory reset. Could you help me?

Which version of Android?
Do you have TWRP installed?
If you do people have been posting that going to Advanced, then tapping Fix Bootloop may work
Otherwise find the boot image of the ROM you have installed, and flash that to the device
If youre on Android 11 on the Pixel, as i found out myself via bootloop, do NOT install TWRP, just fastboot to it to flash zips

I used this command (and tried to boot in slot a), the patched img still won't boot.
Did you managed to flash Magisk with patched boot file?
