Problems in rooting after flashing patched boot.img - Samsung Galaxy S7 Questions and Answers

Hi everyone sorry for the truble and probably the bad english this is not my main language .
I have an old Samsung s7 with android 8.0 that i wanted to root with magisk.
I first tried with twrp but i don't know why i couldn't "install" it, when flashing with odin it failed and made my phone go in like"emergency recovery mode ".
Next i tried without TWRP which i founded is the recommended method.
I did everything the guides i found said but when i am flashing the patched boot.img after the phone boot and i open magisk it isn't installed.
Ramdisk went from yes to no.
I don't know what to do i am sure i used the correct boot img. I transferred them via google driver in .tar maybe this broke something?

please mention the exact steps, we don't have crystal ball.

sorry,
I extracted boot.img from the ap file (it's the correct one i am sure because i used it to flash stock firmware).
Then i transferred the boot.img via google drive to the phone and used magisk to patch it, it said no error and everything worked fine . After that via google drive i brought back the patched file to the pc and used odin to flash it with BL CP HOME-CSC.
When i flash it with BL CP HOME-CS and the patched file the phone boot and ask me to go to factory reset i say yes, then after everything i reinstall magisk and ramdisk went from yes to no but it still says magisk not installed.
I don't know if i made myself clear

so I understood you enabled OEM unlocking, unlocked bootloader in download mode (what was factory resetting device) and after finishing initial welcome setup, you again ensured OEM is unlocked in developer settings. only then, you flashed Magisk, device is still working but Magisk provides no root, because ramdisk is gone.
What is the Samsung ROM version (for example G930FXXU8EVG3)?
What Magisk version you installed?
What options you set in Magisk before patching boot.img? Haven't used Magisk for a while, maybe no options have been asked.

i have enabled OEM unlocking but bootloader mode i don't have the option to activate it (in the passage before going to dowload mode) but the guide i looked said it wasn't needed if there wasn't the option.
I am using magisk 25.2 and they ask no option when patching .

download platform-tools, enable usb-debugging, install ADB drivers, confirm 'adb devices' on phone and push the ROM to phone storage.
Code:
adb devices
adb push path\to\pc\AP_[device_model_sw_ver].tar.md5 /sdcard/Download
uninstall Magisk and install older version Magisk-v24.2.apk
In case you want to use TWRP later, disable the encryption checkbox (only when asked) and disable avb/dm-verity checkbox (only when asked) in the options before patching (not sure these options exist though).
Device should have ramdisk, so do not enable the recovery option for now.
patch the whole AP_[device_model_sw_ver].tar.md5 file with Magisk. notice the file name when finished.
copy the patched file back to PC and rename it AP_[device_model_sw_ver]_magisk_patched_boot.tar
Code:
adb pull /sdcard/Download/magisk_patched.tar path\to\pc\AP_[device_model_sw_ver]_magisk_patched_boot.tar
flash the patched AP file together with BL CP CSC (will factory reset) and wait long time for first boot. finish the initial setup and install (older) Magisk apk again.
if rooting was successful, update Magisk from within the Magisk app.

i tried and did everything but when i try to flash with odin it crashes

please understand I won't answer "please help" or "tried everything" posts. give more information. the patched firmware does not flash? or is that general odin issue?
edit: given instructions were straight from magisk documentation
https://topjohnwu.github.io/Magisk/install.html#instructions
except for using older Magisk. I forgot to tell you how to install. did you figure it out yourself?
In the Magisk-v24.2.apk, do not update to recent version (yet).
In the settings, select Update Channel: custom. then select Custom Channel, copy-paste this link.
https://raw.githubusercontent.com/topjohnwu/magisk-files/4868c83/beta.json
you can now patch the rom file with older Magisk.

ok i managed to do every step you told me i patched the file with v24.2 of magik and falshed with odin, everything went fine. But there is still the same problem the app says that is not installed but ramdisk went from yes to no

You're more likely to get the help you need if you ask your question in the right place. We have a Galaxy S7 section. This is why Rule #1 is to search before posting! We will move your thread there.
An unlocked bootloader is absolutely necessary to root. Rooting means you're modifying images on the device; a locked bootloader will prevent flashing modified images. If you haven't unlocked your bootloader, that's your first step.
I personally haven't had any luck patching the AP file in Magisk either. My suggestion is to flash a custom recovery such as TWRP, then flash Magisk in TWRP. Use the latest version of Magisk - 25.2.

Hm.. then maybe it's true your device does not have boot ramdisk? or the patching failed and removed ramdisk somehow?
try again with "Recovery Mode" option enabled when patching. note you have to press the volume button for recovery mode each time you boot.
@V0latyle recent versions of Magisk running Zygisk may have incompatibilities
https://forum.xda-developers.com/t/...ices-with-old-kernel-3-19-s7-included.4447029
Magisk-v23.0.apk is last version without Zygisk (but afaik you still can disable Zygisk in recent Magisk).

Zygisk is disabled by default, you have to manually enable it when setting up Magisk after root

OEM unlocking should be like the boot loader.
i tried using TWRP and i followed this video doing all the steps
but after the final reboot magisk app is not there and if i try to install it manually it's the same as the immage i already posted.
I found out searching online that after root ramdisk should go from yes to no and that worked. But i don't know why it never says that's installed

It seems like you misunderstand several critical concepts.
First, OEM unlocking DOES NOT unlock the bootloader itself. It simply allows you to. After enabling OEM unlocking, you have to follow the process to boot the device into unlock mode, then you have to follow the prompts to unlock the bootloader, which will wipe the device.
Second, the Ramdisk indication in Magisk simply indicates whether or not the device has ramdisk. This does not change, regardless of whether or not the boot image or system has been patched with Magisk. The only thing you need to look for is Installed: <Magisk version>. If Installed: N/A then you do not have root.
All you need to do is install TWRP, and if you're going to be using the factory firmware, flash the Multidisabler. Then, install Magisk through TWRP. When you reboot to system, you should have root; you'll need to install the Magisk app, but once you do, you should see the version of Magisk next to Installed as described above.

@V0latyle I think paoloooooo is right (see his screenshot) and bootloader is unlocked (otherwise phone wouldn't boot after flashing magisk_patched.tar)

I thought a locked bootloader will prevent flashing anything custom?

right. but afaik it's possible to flash on semi-locked bootloader after the OEM toggle was enabled, but vaultkeeper still armed. at least that is the mistake you're refering to, many people struggle with...

guys thanks for everything i literally don't know why but i tried one last time with patching immages and it had the same error as the immages.
2 days after, i looked into it again and i don't know how but magisk was installed.
Thanks for everything and sorry choosing wrong section and not being very explicative.

Yeah, it would seem that a user would have to do things one of two ways:
Unlock bootloader, flash custom recovery, IMMEDIATELY boot into recovery (do not allow boot to system), wipe /system and format /data, install custom OS...this should prevent KG from interfering
Unlock bootloader, flash multidisabler, wipe data, boot to system, connect to Internet, ensure OEM Unlocking toggle is still visible, if it is KG should be disabled

[guide] root oreo stable with magisk [trial and error method]

Hello folks,
As soon as OREO stable update rolled out, we all were looking for a TWRP and a way to root our MI A1.
I found a way to root MI A1 without breaking WiFi and hotspot.
I will not be responsible for any harm caused to anyone during the flashing.
This may work or may not work for all of you.
DOANLOAD MAGISK INSTALLER.ZIP AND
Keep in mind, keep an OREO stock boot.img as it would be used later.
So here is how you will get it :
First of all, head to the folder where you have installed ADB AND FASTBOOT drivers, launch a command instance there and flash MohanCM's TWRP using command 'fastboot boot TWRP.img' (PS: Rename the .img file to TWRP.img).
Second, the phone will boot in TWRP but wait, here is what you need to do in order to make your TWRP recognize your data partition. It will initially show 0 MB.
OKAY, TO SOLVE THIS WHAT WE WILL DO IS, GO TO WIPE>ADVANCED WIPE>REPAIR/MODIFY BLABLA FILE SYSTEM>SELECT 'DATA' PARTITION>SELECT 'EXFAT'>AND SWIPE RIGHT TO CONVERT THAT 0 MB TO ORIGINAL 51GB USERSPACE.
AGAIN SELECT EXT4> SWIPE TO CONFIRM.
GO BACK, flash MAGISK installer zip(Mount system, data)
Reboot to bootloader.
Now flash the OREO's stock boot.img using,
FASTBOOT flash boot_a boot.img
FASTBOOT flash boot_b boot.img
FASTBOOT reboot
The phone with reboot back in system, with working WIFI AND HOTSPOT.
Next is download official MAGISK app, and you'll be seeing ROOT for sure.
This method worked for me, check if it works for you too.
Thanks,
Kaustubh.rockstar

Use this , you can flash /boot the patched image. and just install from magisk manager
Here is a easier process if you really want to check if the boot.img is compatible:
First enable OEM Unlock in developer settings
- Reboot to fastboot (volume down + power)
- fastboot oem unlock (won't wipe)
- fastboot boot patched_boot.img
- After Android finishes booting, install Magisk Manager.
- In Magisk Manager, use Install and install the latest Magisk with Direct Install
- Reboot and you're done
I think you probably should read the contents of the thread that I wrote. I don't think this thread is about getting OREO STABLE.
It is related with working root for now without TWRP.
AS A TEMPORARY MEANS.
DO NOT COMMENT IF YOU HAVEN'T READ THE THREAD PROPERLY. I'VE BEEN AN ACTIVE DEVELOPER FOR VARIOUS ANDROID PHONES IN THE PAST TOO.
NO MORE DISCUSSIONS.
EDIT : THERE IS NO PATCHED BOOT FOR OREO STABLE. EVEN IF YOU FLASH OLDER PATCHED BOOT, IT WOULD SIMPLY BREAK YOUR WIFI AND HOTSPOT AND I FOUND A WORKAROUND FOR THE SAME BUT WITHOUT TWRP.
What the... reformat data partition just to install Magisk? Magisk can be installed in 5 minutes on stable Oreo, no TWRP needed, nothing gets broken.
You need to zip in the files to system, Don't you? ^^
MAGISK surely would not work without files.

Yes and no. If you boot patched boot.img, which already contains Magisk, then you don't need TWRP. I confirm that steps above mentioned by "Aj.GaLaxY aCE" work. I did the same, even prepared patched boot.img while on Nougat myself, then updated to Oreo, booted patched_boot.img, installed Magisk Manager, installed Magisk to active partition. Wifi and hotspot are working and I didn't lose any data.
Alright, sire. ^^
Thread reported for deletion.
I'm not here to argue with you people. I'm here to help.
Simple.

1. People are messing up using twrp to root
2. Booting via patch boot.img doesn't break your wifi or hotspot
3. You haven't even posted an Oreo stock boot.img
4. There are similar twrp methods also available and no one is willing to put himself/herself at risk
5. If you can get a root by following simple steps,, there is no need to confuse people by this and that method.

TWRP, Magisk, & Xposed for the NX619J

This is a translation and rework of youyim2's executable. I've rewritten some of the batch file to make things more streamlined, as well as translated the whole thing into English. I am not the device maintainer. If you have questions, I'll help as best I can. This is only for getting TWRP, Magisk, and Xposed. You should be able to flash Open GAPPs if needed with no issue once you've got TWRP installed.
Download the zip file. Extract the contents. Run the *.bat file. Follow the instructions.
INSTRUCTIONS:
1) Unlock the bootloader first.
2) Unlock fastboot flashing.
3) Flash TWRP.
4) Reboot into recovery (TWRP)
5) Flash the version of Magisk that is included.
6) Reboot into the system
7) Install the included APK for Magisk. Official Magisk does not support this device.
8) If you want Xposed, reboot to recovery, and flash the included EdXposed zip and the riru-core zip.
9) Reboot back to the system
10) Install the included EdXposed apk
TWRP:
To get TWRP into English (or your language of choice), boot to TWRP recovery. When it shows up, slide the bar to the right to unlock it. After that, tap the button second from the bottom on the right column. This takes you to the Settings menu. In here, tap the globe icon in the top right tab. Choose your language from here.
NOTES:
1) The flashing unlock needs to be run EVERY TIME you reboot into bootloader, as it locks the flash mode every reboot. This type of unlock does not wipe data.
2) DO NOT WIPE /SYSTEM IN TWRP. It will brick your phone.

Did you unlock the bootloader and do the flashing unlock? Both are required for TWRP to flash.
Yes, I did the process completely. I have the last Chinese Rom. The bootloader was unlocked, the fastboot Flash too but when I click the number 4 Is fail flashing twrp and there's a message saying Max limit exceded and too bootloader password Is error.

If you read Chinese, you could try the tool in this thread. It's what mine is based on, and may be better suited to the Chinese version.
Added options to reboot into recovery and bootloader as well as some more translation and other text adjustments.

Yes, I did the bootloader Is unlocked and I did the fastboot unlock but when I try to Flash twrp Is fail with a message exceded limit Max AND too password Is error or something like that. I try with the .exe AND directly with adb but it has the same result.

Hello friends. I have a problem and I can not find the solution .. in the magisk manager some modules are not shown when looking for them, like pix3lify, google framework, camera2api y more. The first time I rooted my nubia and installed magisk manager, the modules were shown and I could install them and they worked, but then I gave a full reset to red mars and since then I have not seen the modules never again. I have already reset the nubia more than 10 times, changed the language, installed other magisk manager apk, and nothing.
this magisk manager does not let me install modules from github and if I download and install a thirdparty zip from the web, magisk installs it but the module does not apply or is not installed for some reason.
Is the same in twrp:crying:
I do not ask for support, but if someone knows how to solve it or gives me any suggestions? please
Thanks

One thing that I have found rather disappointing with all of the "guides" (that can only be loosely called such) is that nobody has explicitly mentioned HOW you have to unlock the bootloader on Nubia devices without downloading something.
In fastboot mode, after toggling Bootloader Unlock in developer settings, one must type:
fastboot oem nubia_unlock NUBIA_NX619J
THEN you can do: fastboot flashing unlock
Flashing a boot image may require you to redo the bootloader flashing unlock to bypass the "This device is corrupt" screen.
Packed up Windows executables aren't exactly helpful for those of us using Linux or MacOS based systems. Even then, the Red Magic Mars packaged bat files/tools didn't install correct drivers for me on Win10. Could never get the device recognized within Fastboot on my Win10 Intel desktop after updating and reinstalling drivers.
There is also another quirk with the Nubia devices that I ran into that I have seen mentioned only once on another device's forum.
If you're running a Ryzen/AMD based system, you may have to issue the fastboot commands on an Intel based system instead.
Why? Beats me. It makes no sense, but after hours of pulling my hair out, I happened to come across a post suggesting it and gave it try.
Typing in the same commands with fastboot in the same OS (xUbuntu 20.04) with the same exact versions of every tool used... failed on my Ryzen desktop but worked fine on my Intel laptop. Had I known, it would have saved me several hours of swapping cables and reflashing software.
Also, for those (like me) who don't exactly like blindly trusting software found on forums.

Pull boot.img from the update archive and use another device with Magisk installed to repackage the boot image for the Mars to flash yourself.
fastboot flash boot modified_boot_image.img
And done.
Due to the risk of bricking the Red Magic Mars within TWRP, I'd rather avoid using it entirely... so I only flashed a boot.img modified with Magisk instead.
One nice thing of note about the Red Magic Mars. It has an actual recovery partition and doesn't use the clusterfluck that is the A/B partition scheme.

-------------------TROUBLESHOOTING-------------------
-------------------------------------------------​
Issues after updating?
If you end up unable to boot or bootlooping afterwards, you most likely have an old Magisk module that isn't playing nice with the new build. There are 2 main things you can do:
1. Flash the new factory untouched boot image. You will of course lose root, and all modules will be disabled. However, it should at least get you able to boot back up quickly and have a working phone if you're in a bind.
2. I would recommend checking Tulsadiver's thread: https://forum.xda-developers.com/pixel-4-xl/how-to/magisk-modules-disabler-booting-magisk-t3990557
Instead of reverting to stock boot image, fastboot boot (NOT FLASH) Tulsadiver's boot image. This will boot your phone in Magisk Core-Only Mode, with all modules disabled but root retained. From here you can open Magisk Manager and disable suspect modules. Before rebooting, go to Magisk Manager's settings and disable Magisk Core-Only Mode. Once you disable the incompatible module, the phone should boot back up.
- See this post (or thread) for more tips / context / an example: https://forum.xda-developers.com/showpost.php?p=82509691&postcount=16
Since Magisk v21.x, Core Only mode has been replaced by using Android's built-in Safe Mode. Booting into Safe Mode should essentially boot you back into your system but with all modules disabled (as well as Magisk Hide). Keep in mind that even after you reboot, modules will remain disabled, unless you re-enable them first. Also remember to re-enable Magisk Hide if you had it enabled before.
Please see @Didgeridoohan's guide for more details: https://www.didgeridoohan.com/magisk/MagiskModuleIssues#hn_Core_Only_Mode
It's also worth mentioning, his guide is extremely well-made and contains a lot of useful information that could benefit all Magisk users and modders. I highly recommend looking through it anyway!
@i5lee8bit - thanks, worked fine on my Pixel 4 XL. However, during the OTA process my console showed me following error message:
Code:
C:\Unified_Android_ToolKit\platform-tools_r30.0.4-windows\platform-tools> adb sideload C:\Temp\pics\coral-ota-rq2a.210405.005-0d148a1d.zip
serving: 'C:\Temp\pics\coral-ota-rq2a.210405.005-0d148a1d.zip' (~94%) adb: failed to read command: No error
The device itself showed something across the lines of exit error code 0.
Everything seems to be running ok so far. Do I have to worry about the OTA stopping to transfer at 94%?

Maybe you should update your platform tools to the latest version: it's v31.0.0 as of February 2021. Your log says you're running 30.0.4.
Hi. This first time happens to me when I reboot the phone the Root is gone and have to flash the magisk_patched again!! Please is there any suggestion on how I keep Root after reboot?

You'll have to re-root after each update. The method used to keep root when updating via OTA was removed from Magisk b/c it was causing problems on Pixels.

Like @Ghisy already said, definitely start with trying newest platform tools. I've had that error come up before but experienced no problems.. weird thing is it happened to my wife's Pixel 4, but not my Pixel 4 XL when I did the updates right after another. So used the same platform tools, PC, etc. Another thing to consider that may help you feel better is that some custom ROMs actually expect that to happen when installing their ROM as a sideload OTA, so could indeed be nothing to worry about.
If it really really worries you, you could always flash the full factory image with "-w" removed from the script file, and either replace the boot.img with the Magisk patched one (rename it first), or flash it separately later. But for now if everything is working normally and it indicates you're on April 2021, I wouldn't worry about it.

What @Lughnasadh said is certainly true; is this what you mean? Or the way I read your question, are you losing root between reboot despite flashing the Magisk patched boot image? Are you sure you flashed it? Are you doing fastboot flash boot (file.img) or doing fastboot boot (file.img)? Make sure you're actually flashing it, not just booting to it. If all else fails, try doing a complete uninstall of Magisk and then start over (hopefully won't be necessary). I've never heard of anyone having the problem you're having though, and it sounds more like you're fastboot booting to the Magisk patched image, and not actually fastboot flashing it...

Ohhh yes thanks to remember me i forgot to write FLASH i was only boot without flash. Thanks for all
im having an issue with getting root back. i followed the instructions and when its time to reboot to the system, i get the splash screen but it reboots back to the bootloader or itll reboot twice and send me to the OS but without Magisk. ive done the factory image thing and still the same thing. i need help
@i5lee8bit Good stuff as usual, updated fine over here! Thanks!
Does anyone know the update process for Magisk now that everything is unified? I used to update manager then patch the boot image again. Is it still the same process from Magisk 22 to 22.1 (today's update)?

If you are already rooted on Magisk 22.0, you should be able to just update the app to 22.1 and then do the direct install method to update root (I just did this and everything was fine using Beta channel). If you were unrooted and installing root for the first time (rather than updating), patching the boot image would be the way to go.
@Lughnasadh Yeah, I'm already rooted on v22. Just did the app update then direct install and it worked fine! I've been in the rooting game since the HTC Desire but the latest changes with Magisk confused me for a minute there!
Thanks

Hey sorry, had a really busy week and haven't been on XDA in a few days. Did you get this resolved yet?
My first thought was you were probably bootlooping due to a Magisk (or Xposed) module that doesn't agree with the new firmware. Because that could cause a bootloop, kicking you back to bootloader and eventually forcing a safe mode boot, disabling all Magisk modules and MagiskHide... only problem with this is that afterwards, you should still have root, though with all modules and MagiskHide disabled (I'm more attuned to believe this was actually your case, not that you were "losing root" per se. When it boots back up, are you able to go into Magisk Manager and toggle your modules? Also, what does it say on the manager's home page under "Magisk" and "App" sections? (the parts titled "Installed"). You'll also want to make sure you're running / have installed Manager v22.0 (if flashing the Magisk patched image I provided in the OP; you can always update Magisk / Magisk Manager to v22.1 afterwards).
Sounds like you already tried flashing the 04-2021 full factory image too? Which would eliminate the possibility you maybe flashed the wrong boot / dtbo / or OTA files. If all else fails:
Re-flash full factory image (remove the -w flag in the script file - it sounds like you already did this so I'm assuming you know why) and it should boot unrooted - but you should be able to use the phone.
Make sure Magisk Manager version is 22.0 (i.e. same version as patched in the OP, though 22.1 would work fine too), and if not, grab it from topjohnwu's github and install it.
Reboot to bootloader and flash the Magisk patched boot image in OP (fastboot flash boot coral-rq2a.210405.005-magisk_patched-22.0.img).
Boot the phone. Hopefully you're done.
But if it bootloops, boot it in safe mode (this will disable all your modules as well as MagiskHide). Reboot again.
Open Magisk Manager and all modules should be disabled... time to test for the culprit!
Remember to re-enable MagiskHide, if you had it enabled before. It does not automatically re-enable like it did back in the pre-Magisk 21.0 days. Wow, this post ended up being a lot longer than I expected, and you might not even need the help anymore, lol (though I hope you did get it resolved sooner than later). But at least I can link to this as reference for future guides. Best of luck to you.

Exactly as @Lughnasadh said, this is what I do too (except I'm using stable channel). Direct Install used to give me problems, but that was almost a year ago (a bit after I first got the phone last March), but it hasn't given me any problems since. Even in the very unlikely chance it did cause problems, you could always re-flash the patched boot image in the OP and then patch the stock boot image yourself using Magisk Manager and flash it.

Nah, you're good fam. I ended up accidentally flashing the factory img and I'm back with root. Thank you for your help and the guides

LZMA (Elementalx), TWRP, Magisk -> change LOS 18.1 recovery to TWRP in order to get root access,

So, backround is, I want to use AFWall+, which requires root, which I would like to use Magisk for.
In order to get Magisk I need TWRP, I learned so far.
I run LOS 18.1 and I used the lineage recovery/fastboot to flash it (according to the offical LOS-guide).
Changing the recovery is not the easiest thing for me.
Found this thread: https://forum.xda-developers.com/t/from-lineage-recovery-to-twrp-recovery.4253669/
but this seems to be very Samsung specific using Odin (I use a Pixel 4)
I also tried this guide: https://www.droidwin.com/boot-into-recovery-from-fastboot-mode/
but this just "deleted" my OS.
This is why I will be asking a few questions prior starting a new attempt, so please bear with my incompetence
At TWRP I read, I have to install a LZMA ramdisk kernel in order to get TWRP (https://twrp.me/google/googlepixel4.html).
I would go for elementalx, assuming it does support lzma.
From here things are getting tricky for me.
TWRPs guide tells me to get the kernel first, at Elementalx I get the instructions to use TWRP to install
It does say however its not neccessary to install TWRP permanently, but I would like to, because no matter what I want to do with my phone it requires TWRP. So I would like to change the recovery permanently.
The easiest way to do all of this seems to be this guide: https://elementalx.org/how-to-install/
But that will not change my recovery permanently...
What I would do (using a videoguide, because you know, I'm a noobish newbie):
1. Download TWRP img + zip, Magisk zip, Elementalx zip to my fastboot folder
2. Copy the Zips of TWRP, Magisk and Elementalx to my device
3. On my PC -> in the fastboot folder I run cmd as administrator
4. boot into bootloader
5. using cmd -> fastboot boot twrp.img
6. using TWRP -> flash the custom kernel
7. using TWRP -> flash TWRP
8. check if TWRP was proper installed: in TWRP -> boot -> recovery
hopefully the recovery was replaced
9. using TWRP - > flash Magisk
10. reboot
Would anyone please tell me if this will work?
Is there anything I need to do to avoid horrible things to happen?
This is not a request to blame something that could happen on someone afterwards. I just want to minimize the risk...
You can just flash the kernel from fastboot no twrp needed. Just fastboot flash boot boot.img.
You can have magisk patch a boot image then flash it from fastboot as mentioned above.
Usually its just recommended to fastboot boot twrp.img instead of flashing it to the actual device incase you want to revert back and install an OTA.
You can also just download the magisk apk from the device to patch the boot image, flash kernel from fastboot, then reboot with root and have magisk finish doing what it needs to do.
Thank you.
TWRP got stuck booting: I see the logo, "teamwin" and the version used 3.5.2_10-0
Everything was up to date, I'll try it again with an older version of TWRP.
Well, I dont know how to boot into LOS. It just froze on the mentioned screen.
Has anyone a idea what to do?

Ok, I tried it my way - it wont work (of course). Maybe TWRP is still not supported for Android 11.
Now I'll try it your way (thx again).
In order to flash the kernel, I'll have to unzip the elementalx file, I assume. And boot the avaible image, which is called "dtbo.img".
I'll give this a go...

fastboot flash boot boot.img did not work. I renamed the file to boot.img (did not mention this before).
Tried it twice, but nothing worked afterwards, not even recovery and I was not able to turn the device off.
Had to flash LOS again.
I also tried flashing the kernel using sideload while flashing the rom again.
Sideload did work, BUT the wifi was not working at all.
I dont want to bother you, but might there be another way?

Wifi is usually a kernel module that gets loaded through an init script on boot. It's possible to build the wifi module built-in to the kernel, which makes it so it doesn't have to load separately through an init script.
So if youre not using the stock kernel you'd have to ask whoever makes the kernel you are using.

Magisk should not be that complicated. All the hard work has been done and can be found in Magisk documentation. There are install instructions for just about any type device and if there is LOS for your device I'm sure it is covered. The latest Magisk is not TWRP flashable the same way as it used to be and newer devices often don't have ramdisk in boot image and root is achieved thru recovery instead. You referenced several threads and guides but no indication of Magisk instructions. Read the Magisk installation instructions for your device type, they're not just suggestions, they work.

How To Guide Rooting the Google Pixel 6a

Rooting the Pixel 6a is just about as easy as any other factory unlocked pixel, but because so many people have had issues with unlocking their bootloaders, I figured I'd post my exact personal steps I took when a Pixel 6a came into my tech shop to be rooted, and I discovered the current bug with Rooting
What You'll Need:
- June 2022 Firmware OTA Update Installed at least: Do this on device. Do Not download the OTA update from google's firmware website.
- ADB/Fastboot/Google Drivers for Windows: I use this to install- ADB 15sec Installer
- Magisk Manager APK: Github - Magisk Github Releases
- Firmware Matching Currently Installed: Google FW page - Google Official Firmware Downloads - you need this for the boot.img file
- A Windows Computer
- A USB-C cable to connect to your phone to the computer
OEM Unlock Bug
With early units sold by Google, they're shipping with a bug where OEM Unlock stays grayed out. Here's the only way I got around this issue
1.) Log out of any Google Account on the device
2.) Connect to Wifi, check for updates without your sim card in the device. There is a bug where it will potentially download the update for your carrier sim
3.) At minimum, you should get the June 2022 security patch update. Run the update and remember which update it is for when you download the firmware to get boot.img
4.) When the update is finished, Factory Reset your device either from settings or Android recovery
5.) Go through Android setup without sim card in, and don't connect to wifi, finish setup without logging into a google account or anything
6.) When setup is done, connect to wifi and put your sim back in.
7.) Pay attention in your notifications for "Preparing your Device" notification.
8.) When that notification pops up, enable Developer options (tap build number a bunch of times)
9.) OEM Unlock should be possible to enable now. Also enable USB Debugging
Pre-Root Setup
1.) Install Magisk Manager from Github
2.) Use 7zip (or any other ZIP opening program) to extract the boot.img from your firmware download from google
-- the boot.img is inside another zip file that's in the download from google. very easy to get
3.) Put the Boot.img on your phones internal storage
4.) Open Magisk Manager, and select your Boot.img from internal storage. Patch the boot.img to make it a rooted boot.img
5.) With your phone connected to the computer, move the magisk_patched.img from sdcard/downloads to your computer
6.) If USB debugging is properly enabled, now you can open CMD and reboot to bootloader with
Code:
adb reboot bootloader
Unlocking the bootloader
1.) With the device connected, OEM Unlock enabled, and booted to bootloader, you can unlock the bootloader with the following command
Code:
fastboot flashing unlock
-- If nothing changes on your phone screen, use Device Manager to make sure the device is recognized via google drivers: vid here on that - Quick Fastboot Drivers Install Tutorial
2.) On your phone, use the volume keys to select Unlock Bootloader, then hit the power button, device should reboot back to bootloader
3.) flash the boot partition with the magisk patched boot.img
Code:
fastboot flash boot magisk_patched.img
4.) Now you can reboot back into your device and you should be rooted!
Code:
fastboot reboot
Congrats! Now you're bootloader unlocked and rooted! GrapheneOS is already available if you want a degoogled rom, haven't seen another rom pop up yet
all done from there
updating your device when rooted
I do not have a pixel 6a specifically for this right now to confirm this will work, but on every other device with OTA's, this has been my process.
1.) Download your OTA using the system update part of Settings
2.) When it pops up and is ready to restart to finish installing the update, DO NOT CLICK RESTART IN SETTINGS/SYSTEM UPDATE
3.) Go to Magisk Manager, and select Install next to Magisk
4.) Select "Install to Inactive Slot (After OTA)
5.) When its done patching the boot partition, hit restart in Magisk
Your OTA Update is now rooted
To save time and effort here is the magisk patched boot.img for June 2022 patch level, Carrier Unlocked 6a from the Google Store. Make SURE you are on build SD2A.220601.003 before flashing!
To get the `OEM Unlock` option in Developer Options to work, it's simpler to just manually flash 12.1.0 (SD2A.220601.004, Jun 2022, Verizon, Verizon MVNOs) and then wipe.
Even though it's label as Verizon, it should work for all carriers.
Hello, if we have already unlocked the bootloader, we just have to do this: start cmd then fastboot flash boot magisk_patched.img then restart the phone?

Correct, though I would probably fastboot boot first just to make sure it boots up ok. When it does you can reboot to recovery and flash it.
these instructions sound like "the usual process", but for the 6a isn’t there something to patch regarding vbmeta as well?
(never had a phone that "needed" this, but in my understanding it "should" be necessary with the 6a? won’t have time to try out myself before the weekend, just asking ..)

As this thread ages, not everyone will have the June 2022 update. That's why I suggested/put the steps in to do it themselves with matching firmware to what their device is on.

(never had a phone that "needed" this, but in my understanding it "should" be necessary with the 6a? won’t have time to try out myself before the weekend, just asking ..)

Correct, these are basically the usual steps. There's nothing regarding vbmeta flashing in this case of just rooting stock firmware. You only need to do that with ROMs (GSI's mainly)

3.) flash the boot partition with the magisk patched boot.img
Code:
fastboot flash boot magisk_patched.img

Just a heads up. As already told by ctfrommn, it's always a better approach to first boot the magisk patched boot file. And if everything works well and good, you could then Direct Install it via Magisk.
Although directly flashing should also work, but its always better to be on the safer side.

I followed your steps to a T. Still can't unlock. I'm convinced there is a fault with my device itself at this point.

they will warranty replace if it for sure fails still. Its a silly situation, but mistakes happen

I may not be very active on XDA, but have been rooting and rom'ing devices since the palm pre, first android phone was the droid x. I've never heard of this step, its never been needed. Its an extra pointless step that is just tethered root. You don't need to do it. As long as you don't download a random Boot.img, like the one for some reason attached to a reply on this thread and get it yourself from the firmware matching your device OR flashing Magisk via TWRP/Lineage Recovery with adb sideload, there's no reason to fastboot boot the boot.img.
You may have never run into an issue flashing a boot image but I've built thousands of roms and kernels and have learned the hard way more than once to measure twice, cut once.
That said, as long as you're simply patching a stock boot.img it's likely not an issue.
Followed all steps, on SD2A.220601.003SD2A.220601.003. OEM unlock still greyed
Nice work, Kaptinboxxi. Everything worked fine. How should we handle updates after rooting? Will a security patch break root? If so, what is the best process to root it again?

Yes, each update will require reflashing a patched kernel for the new build.
You can also do the "Install to Inactive Slot" method in Magisk to update and keep root. This has been a bit of a hit and miss for some people on the Pixel 6 series, though. The misses may be in large part be due to people having modified their partitions or not restoring the necessary images while being on a custom kernel.

Good call...I guess I've never messed with that as I flash so many kernels anyway.

That's what I've done with my OnePlus 7T for the last three years. Any repercussions for doing it this way versus patching the kernel?
