How to use Magisk??? (add lost txt) - OnePlus 3T Questions & Answers

Hi to all
I have rooted OP3T and every time when I install new update, BETA small or full version zip file, I need again to install stock.zip from boatloader , then again, install TWRP and Super Su.
I hear that with Magisk I can easy install any update without lost TWRP and Root. I have flash Magisk and install from Google Store Magisk Manager.
So my question is how to install new update with Magisk and dont lost TWRP and Root?
Please tell me step by step
thx a lot for your answers

Magisk doesn't touch the recovery. And you'll still have to flash the Magisk zip since the boot image is updated whenever you update your system (Magisk modifies the boot image).
What does stay after an update (as long as you don't wipe /data) is any Magisk modules that you have installed. If you have a bunch of modules that change build.prop values, debloat system apps, change screen density, replaces system UI sounds, etc, you won't have to do those changes again after an update. They are found in the Magisk image in /data and will be loaded by Magisk at boot.
Even if you've wiped /data, it's just a matter of flashing the Magisk and module zips in TWRP after updating your system. No tedious manual editing of build.prop or deleting apps, etc. It literally takes seconds...
If you have issues with loosing TWRP after an update, you can easily fix that, right after updating. Just keep a copy of the recovery image on your device and flash it in TWRP.

Can't flash Xposed zip on Nougat: /system could not be mounted

I'm thrilled to know it finally supports Nougat. Thanks rovo89 and all the developers!
Now I have issues installing the zip. I tried to use TWRP to flash the lastest zip (Pixel, 7.1.2, sdk25, arm64), but it kept saying "/system could not be mounted". Here's the log:
https://pastebin.com/89wefwCR
Same problem; Pixel Xl running PureNexus and Magisk 13.3
pixel xl here. xposed could not be installed from recovery, but could be installed from the xposed installer app. I could also be uninstalled from that app. However, uninstall exposed zip could not be flashed, for the same problem - can't mount system. I'm not comfy messing with xposed until uninstall zip works. That uninstall zip has saved me so many times.
I just figured out the way to install Xposed v88 on a Pixel XL phone.
If you have used Xposed on other diveces before, you probably know that the Xposed framework you are about to install is a .zip package , and you may want to use a 3rd-party recovery (like TWRP) to install it, just like you always did with other android phones.
However, the recovery method does not work with Pixel, at least at this time.
This is caused by Pixel's totally different partition plan, known as "A/B system partition"(which means there are two /system partitions). It seems that TWRP can't perfectly support Pixel's A/B partitions. (But why TWRP can install Super SU flawlessly into a Pixel? Anyone have an idea?)
An alternative way is using Flashfire to install .zip packages, and Flashfire supports Pixel's partitions.
So here's my attempt to install Xposed with Flashfire:
root the Pixel by fastboot boot twrp.img and install SuperSU.
reboot and install Flashfire.
copy xposed-v88-sdk25-arm64.zip to Pixel's internal memory. (xposed-v88 could not be the latest version when you are reading this)
run Flashfire, select the zip package, choose Slot A, check Auto-mount and Mount /system read/write
hit FLASH.
after reboot, install Xposed Installer (apk) and you will see Xposed is ready for use.
note: I reset my Pixel by flashing factory image (fash-all.bat) and I'm not using Magisk.
What is the advantage of using flashfire over the method I described above?
my method is:
1) open xposed app
2) hit install
However, if xposed jacks up your phone (not saying that xposed will do that, but I know messing about with it I've had situations with certain modules that wouldn't let me boot into system), you can't flash the "uninstall" zip with flashfire.
That's what's stopping me right now. I know I can always go back to a TWRP nandroid, but sometimes I don't have a zero day backup on hand. I liked the safetynet (pun intended) of always being able to flash uninstall xposed zip from recovery.

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!!

- copied magisk uninstall to phone memory
- 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!

1) Do not update via Magisk Manager.
2) Do not update via TWRP using the zip you can download via Magisk Manager.
3) Uninstall Magisk using Magisk uninstaller (ZIP).
4) Boot to Android.
5) Reboot to TWRP
6) Install V17 ZIP via TWRP and boot to Android.
If you HAVE INSTALLED and got a bootloop:
1) Download the uninstaller ZIP.
2) Enter TWRP during the bootloop.
3) Uninstall using the uninstaller ZIP.
4) Boot to Android.
5) Download V17.
6) Reboot to TWRP and flash the V17.
7) Boot to Android it it should be working.

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...

Magisk manager showing Magisk not installed after reboot

Phone: Huawei P20 Lite
ROM: Omni
Magisk: 20.3
Downloaded the Magisk.zip file through Magisk manager.
Flashing the Magisk zip using TWRP is success.
But rebooting to system showing Magisk isn't installed.
So I was to try flash it again. But booting TWRP is failed.
It ended up booting to system. At this time Magisk manager showing it as installed.
To be concluded:
1) Rebooting to system will delete Magisk root.
2) Rebooting to recovery (TWRP) will fail and boot to system. In that case Magisk manager saying root installed
Any solution to make root access stable and keep TWRP in recovery partition?

you can patch magisk to your firmware and install (flash) it with odin. but from my experience, the jhonwu method is really work (magisk in system as root) but I am unable to install twrp alongside that system. I mean yes indeed I can flash twrp into the device but then I lose root access. (many case I got random restart all over again).
now I am kinda confused because I need root and also that twrp is really usefull tool for idiot like me.
FYI; I already try install twrp pre-patched magisk from geiti, but its very unstable. random reboot, and sometimes I am losing the magisk it self (magisk manager suddenly show that magisk isnt intall). thats why I am kinda prefer to root with jhon wu method,
can you guys help me how to flash twrp without ruin magisk that already installed on patched stock firmware?

Question How To Update System While Keeping Magisk

I have several modules in Magisk app and couple of apps having root authority after get root with Magisk (like Tasker). Now I want to update system while keeping my magisk apps and root-to-use apps working without any risk of stucking in reboot after install a new ROM.
Could I just firstly patch the boot.img of objective ROM in Magisk, replace the boot.img with magisk_pathed_XXXX.img and flash all the .img files needed? Will this way work? Or any other ways?
while flashing a newer rom version, the magisk modules are not deleted. After flashing the new version install magisk again and everything is working well. Before updatating the rom version "restore hide magisk by itself" if you have enabled it.
If you have modules like SmaliPatcher - These will cause a bootloop after update.
Disable all modules before any update and make sure to Restore the Magisk App if its hidden.

I take from your description that you are flashing a fastboot ROM. In that case you are correct, i.e.
take boot.img from new ROM, patch in Magisk and copy back into the original installation folder. Simplest is to rename the original boot image and name the new magisk boot image: boot.img
now you can simply start the installation batch and it will automatically install the magisk-patched boot.img
If you are using TWRP to flash the ROM this is not needed, just flash the corresponsing magisk installation ZIP/APK in TWRP right after the system update and BEFORE rebooting.
In addition @JazonX gave a good advice , but it really depends on which modules you use.

Update lineageos OTA update and keep root access.

Hi
I installed LineageOS 20 on OnePlus 9 with the instructions on official wiki. Then I root my phone with Magisk. I install Magisk by sideloading the Magisk ZIP file and then install the apk as it's been explained in this video. Now I can't update the OS with updater in system settings. I find this guide that explained I need to uninstall and restore images in magisk then update my phone and reinsatall magisk before reboot. But magisk didn't create a backup during installation.
I followed this instructions to fix magisk stock backup does not exist
I create a backup with this guide and lineageos boot.img file and I can now restore images in magisk but I get the same error when trying to install the updates. I noticed that there is also dtbo in backup function and I did the same thing for backing up dtbo.img and it doesn't solve the problem. Is there anything I'm missimg. Should I use vendor-boot.img instead of boot.img?

I just learned that Magisk doesn't work after an OTA update. What I do is I normally update, uninstall Magisk, boot into Lineage Recovery, sideload the Magisk .zip file via ADB, reboot, and finish setting up Magisk through the app. There are other ways to do this, but this method works well and doesn't need anything special. Works for me!
Alteratively, look here.

I was exactly looking for this for my SM-T290, which also runs LineageOS 20. I think it is the most easy to deinstall Magisk root from the Magisk Manager, apply the update and then reinstall it. I think this also works with TWRP???

I'm installing an update right now. I would imagine it works with TWRP as well, but I only recently started using it.
I realize that this may be a late reply, however, there is no need to do any of these convoluted processes.
Here is what I do, flash the Magisk as a .zip in Lineage recovery once and set everything up. Once the Magisk install is working you can apply OTA updates normally without Magisk and root being removed. On my OnePlus 7 Pro which is an A/B device I just install the OTA and hit reboot with Magisk seamlessly persisting and nothing else being required to preserve or reinstall it. The reason that this works is because the Magisk.zip installs an addons.d script which automatically runs after OTA updates and takes care of Magisk for you.
I installed many Lineage OS 20 OTAs and I never had to touch Magisk at all, it is always installed and working with no intervention whatsoever. Keep in mind that this will only work on A/B devices with Lineage recovery (which you should all be using anyway).

Well, I came to the fact I have a problem with TWRP. It uses OpenRecoveryScript for OTA updates and should also run addon.d scripts after it (Magisk uses this to survive an OTA). The only problem is that the scripts should run after the OTA flash, but for me, it doesn't. So I need to manually reflash Magisk and Gapps after installing an update. My data is encrypted, but I edited the addon.d script to flash the ZIP from the external SD card.
