Oneplus 6 and magisk (stuck in fastboot )

hi guys,
my op6 is running stock oos with magisk as root. My phone worked fine for several months. Today I tried switching magisk from the stable version to canary by first upgrading the manager app and then hitting the direct install option. This failed several times and I got an error saying:
! Unable to unpack boot image
I thought this could be fixed by a reboot, but well... it wasn't. Now the phone only boots into the bootloader. I booted into twrp and tried to uninstall magisk via the uninstall.zip. This fails with error
-Unpacking boot image
! Unsupported/Unknown image format
- Unmounting partitions
cd /tmp/repackorig/ && /sbin/magiskboot unpack -h '/tmp/repackorig/boot.img' process ended with ERROR: 1
Error unpacking image
I don't really know what this means. I'm guessing my boot.img is corrupted?
Is there any way I can solve this problem without a factory reset? Can I just flash the stock boot.img via fastboot?
Do you have any idea what went wrong here, so that I can avoid the error next time?

Yesterday I broke op5 during the magisk update. The repair was simple, flash stock boot.img as boot partition.
I flashed it from TWRP.

Try dirty flashing your ROM without flashing magisk.

I'm also facing the same issues. Tried updating from the Magisk App. Didn't receive any error messages. After reboot I'm stuck in fastboot mode and I cannot access recovery. I do not have a backup of the data on this phone.
Is there any way I can still (temporarily) access the data? I'm panicking a little bit. My OOS is stock and rooted and hasn't been updated in about a year. I'm not sure if I can still figure out the specific OOS version that is installed.
EDIT:
Have been trying to flash the stock boot.img with fastboot. I've tried both 10.0.1 and 10.3.0 so far. Both resulted in the "BOOTLOADER UNLOCKED" warning and got stuck there. 10.3.1 is my last option, because I don't think I've updated this device since. Would it make a difference if I tried to do it from twrp?
EDIT2:
I do however have access to the recovery mode now. If I'm not mistaken this means I might be able to extract the data.
EDIT3:
The recovery mode is not asking me for my unlock pattern (which I think it should be doing) and is not showing up under 'adb devices'. I've tried flashing the boot.img of all OOS versions I can think of with fastboot, nothing will let me boot back in or let me access adb through the recovery. Am I ****ed?

Maybe it's worth trying change the slot and see if it will start? Of course from the fastboot level.

I managed to fix it as well by flashing the stock boot.img for my software version to both slot_a and slot_b using fastboot. I left the active slot setting alone otherwise.
Afterwards I booted into twrp through fastboot and installed blu spark twrp and magisk 21.4 from there as a user suggested on the Magisk github: https://github.com/topjohnwu/Magisk/issues/3924
Note that github link also has a solution to flawlessly upgrade to latest Magisk without data loss but I haven't had the time to look at it.

[Help] OP7Pro only boots to Bootloader, not detected by Fastboot

As the title says, my OnePlus 7 Pro now only boots to the Bootloader and it isn't detected by Fastboot on my PC. I recently extracted a boot.img from the latest (10.3.8) OOS firmware, patched it with magisk, then flashed in TWRP and booted to system. I realized I forgot to reinstall TWRP so I flashed its installer in Magisk Manager then directly installed Magisk. This may be the reason why I can't boot anymore... I most likely can use EDL and MSM to restore (hadn't tried it yet), but I rather save that as a last resort since I really don't want to wipe my device. I've already tried installing a bunch of adb and oem drivers to no avail. Is there a way to use EDL to boot a twrp.img, perhaps?

Well turns out it was a driver issue. Installed proper drivers and got fastboot to work again. Booted TWRP and dirty flashed stock firmware, TWRP and Magisk.

Root /Magisk error in boot, possibly boot loop.

We received a new 8t and proceeded to do root and unlock on it.
Here is my process and problem.
Unlocked bootloader.
Updated phone to recent version via OTA update.
Downloaded update via Oneplus website.
Extracted payload.bin VIA python.payload dumper.
Moved boot.img to phone and patched it with magisk (select and patch a file)
Moved patched image to PC and ran adb
Fastboot flash boot patched image name.img
rebooted , now its caught in bootloop.
Tried fastboot --set-active=a and it didnt make a difference.
When looking at adb devices it shows the attached phone as unauthorized.
Dont know if this helps
Can get into fastboot

You flashed the OS to the bootloader. Not sure how to help you, man. Maybe try the EDL Tool. That worked for me. Also, always install TWRP and flash magisk zip through TWRP. It's foolproof.

TWRP doesnt work with android 11 or the oneplus 8 as far as I know, last time I looked.
Did a tool and fixed the crashes and bootloop, then followed a youtube video and guide.
Found out I ended up doing a different OS version that didnt match.

TWRP for the 8T works reasonably well. See https://forum.xda-developers.com/t/...recovery-project-8t-kebab-2021-09-04.4302449/

[Help!] Can't root my OnePlus 7 Pro

Hi,
with the latest Magisk update I noticed the missing Magisk Hide and SafetyNet fix. So I decided to go back to Magisk 23. After a few unsuccessful attempts, I don't know what happened but now my phone is no longer rooted. So I tried some usual methods to re-root the device but nothing to do, still no root
I have used boot.img patching way with Magisk but when I send ADB command "fastboot flash boot magisk_patched.img", it seems to work fine but after reboot there is no root
So I tried the other method by booting the device with patched boot.img using ADB ("fastboot boot magisk_patched.img") then I open Magisk Manager but in the installation section there is no "direct install" option as it should be.
I also tried flashing Magisk.zip via TWRP as I did long ago and TWRP seems to do the job well but after rebooting again no root...
Any suggestions?

even though you don't have root, i suggest flashing the stock boot.img and then rebooting to be really sure that root has been removed. and then flash the magisk patched boot.img.
are you using the latest adb and fastboot? you can get the latest from here. https://developer.android.com/studio/releases/platform-tools
fyi, i just updated to magisk 24.1 and enabled zygisk. i'm using @kdrag0n's universal safetynet fix. google pay works. i don't have any other apps that i need to hide magisk from.

How did you get this to work? I am on the latest OP7P OOS (11.0.5), and I haven't been able to get my phone rooted, even though I installed the boot.img I patched using Magisk v24.1.

i'm running 11.0.5.1.GM21AA. i was already rooted with magisk v23, so i updated the magisk app to 24.1, and did a direct install to update root to 24.1.
but for any os upgrades, i download the firmware zip from my phone to my pc before installing. i extract the boot.img from the zip with payload dumper, patch it with magisk, and then flash it via fastboot. this way i know for sure that i'm using the correct boot.img. if you need the firmware zip to extract the boot.img from, you can use the oxygen updater app to download it.
did you use the stock boot.img for patching?

Yes, I used the stock boot.img that I extracted from the 11.0.5.1 file that was downloaded as the normal OTA update from OnePlus. I patched that boot image with Magisk v24.1 that was already installed on my OP7P.
Then, I flashed that Magisk patched boot.img using fastboot onto both A and B slots (I switched slots by booting into TWRP 3.6, since I didn't see a way to switch slots with the now-loaded OnePlus Recovery Mode).
When I rebooted through the patched image, the phone came up (which is good!), but Magisk says that I don't have root (which is bad!). I haven't figured out how to fix that.
Could you PM me your patched boot.img? I could try flashing that to see if my OP7P acts any differently.
Thanks!

OK, I'm 100% positive that Magisk v24.1 patched my OP7P OOS 11.0.5.1 boot.img properly.
I extracted the 11.0.5.1 boot.img file from the OTA image that was in my .Ota folder from my phone. I extracted boot.img from the payload.bin file using two different methods of payload-dumper. Both boot.img files had the same SHA-512 checksums, so they were identical.
I also downloaded a copy of the Magisk v24.1 patched boot.img from the intenet and compared it to my Magisk v24.1 patched boot.img file. Again, the SHA-512 checksums matched for the two patched files, so I am sure that I have a properly patched boot.img file.
Note that my OP7P has loaded the full OOS 11.0.5.1 Stock image, so I currently have the OOS Recovery Mode and I do not have TWRP Recovery Mode.
Maybe I am doing something else wrong during my installation that is keeping me from getting root?
Here is the process I followed with my patched boot.img file:
I boot into Fastboot Mode
In Fastboot Mode, I go into TWRP Recovery Mode by typing: fastboot boot twrp-3.6.0_11-0-guacamole.img
After rebooting into TWRP Recovery, I installed the 11.0.5.1 OTA by doing an Install > Browse to the .Ota folder for the OTA .Zip file.
After the OOS 11.5.0.1 OTA installed, I rebooted back to Fastboot Mode (before booting normally) by selecting: Reboot > Slot A > Home > Reboot > Bootloader
Once I am back into Fastboot Mode, I type: fastboot flash boot magisk_patched_boot.img
In Fastboot Mode, I type: fastboot reboot
After I have rebooted back to normal mode, Magisk v24.1 is already installed and I don't do any updates to that. When opening Magisk, my screen flashes a couple of times before giving me a Toast pop-up that Magisk was denied Super User access. When I look at the Magisk App screen, it says that the App is installed, but that Magisk is not installed.
Are there any steps that I am missing?

Well, I finally got OOS 11.0.5.1 rooted with Magisk v24.1.
I ended up wiping my data and installing a fresh install of OOS 11.0.5.1 (Not sure if this is necessary, but I skrood up along the way and had to wipe as a result).
The one thing that was different this time around was that I disabled encryption/lock before flashing the Magisk-v24.1 patched boot image. I suspect that was what helped me make it to the finish line this time.
Good luck out there!
¿GJ?

i'm glad to hear that you got it figured out. sorry for not responding sooner with a patched boot image.
i don't use twrp, so my method of upgrading and patching is different than yours.
my only guess as to why you were having trouble before is maybe you were flashing the magisk patched boot image to the wrong slot. if you run into a similar problem in the future, you can try flashing the magisk patched boot image to both slots. but it's a moot point now. enjoy your finally rooted phone!

Hey, @altwu - I used TWRP to switch between slots when flashing the Magisk patched boot images. I had patched both slots (as best as I could tell)
If you don't use TWRP, how did you switch between slots prior to flashing the patched boot images?

you can use fastboot to switch slots.
fastboot --set-active=a or b
i don't know if it's necessary, but i reboot the bootloader with "fastboot reboot bootloader" after switching slots.
i've never tried this, but you can also specify what slot when running fastboot flash, like "fastboot flash boot magisk_patched.img --slot a".
check out "fastboot help" to see the different options.
i haven't had to play around with slots though. when an update is available, i'll download the zip to a computer and then go through the normal update process via the os. after the update is done, the phone reboots and the correct active slot is set.

Thanks for the feedback, @altwu.
I am having issues getting my SMS notification sound working on my fresh(er) 11.0.5.1 installation. I haven't seen anybody respond back yet, and I am beginning to suspect it's just a problem on my OP7P. If I don't see anybody responding back by tomorrow, I'll assume it's "just me".
I am thinking about doing a total wipe again to see if it will clear up the issue I am seeing. I will end up trying your installation route this time to see if it helps at all.

OP7 Pro - CrashDump Mode when starting the device

Hello community,
I kind of ruined my phone into this CrashDump Mode state. Which prevents me from using my phone at all. I'm pretty sure it is 'bricked.
I hope someone could give me some guidance to fix my phone again.
What do I want:
I wish to have the original OxygenOS back on my phone (stock).
What caused the problem:
My goal was to root my phone by unlocking the bootloader, installing Magisk and flashing the ROM from Magisk. Unfortunately, after doing all of this successfully there were some issues. One of them being slow restarts. It could take up to 20 minutes for the phone to start. Other than that it made the phone quite unusable as the media sound didn't work neither did the wifi and microphone. Making me unable to listen to anything but also couldn't make calls. For that reason I decided to unroot the phone again. I used the in-app Magisk full uninstall button to do so. After doing this, the phone didn't boot anymore. It was stuck at the boot loader unlock warning screen. So I figured I had to flash my latest version of OxygenOS on the phone. I grabbed a guide to do this manually on the XDA forums. However, this was a guide for Android 10 I believe. So it didn't seem to flash all the image files I saw listed after doing the payload extractor. This resulted in my phone booting up to the CrashDump Mode. As there were no guides for the version 11.0.5.1, I decided to use a tool listed here on the forums: https://forum.xda-developers.com/t/...ck-twrp-factory-image-stock-recovery.3358711/ However, this is only for version 10 instead of 11. This also didn't seem to work.
Steps done:
Unlocked bootloader:
- Basically by just using: "fastboot oem unlock"
This went successfully.
Rooted the phone:
- Installed Magisk and my boot.img on my phone.
- Created an .img with Magisk.
- Ported the created .img to my pc.
- rooted the phone with fastboot by flashing the .img on my phone for boot_a and boot_b
This went successfully, the phone was rooted.
Unrooting and stock recovery:
- Used the uninstall button within the Magisk app on the phone.
- Tried to manually flash the OxygenOS version 11.0.5.1 on my phone. Note: only a few images were then as they were the only ones listed in a guide.
- Tried the tool listed above.
This all failed.

This is how I go back to stock
You can use MSM tool to revert OOS, or you can try this step:
1. Reboot twrp/lineage recovery, format data. Reboot bootloader
2. Fastboot boot into TWRP FBEv2
3. Sideload official TWRP 3.5.2.9-0 installer (found on TWRP website). Reboot recovery
4. Copy OOS 11.zip to internal storage or otg drive. Flash OOS 11.zip. Reboot recovery again
5. Format data in OOS stock recovery & Reboot
6. After boot into OOS 11, just local upgrade rom .zip again, you will have OOS on both slots
In your case skip to number 2 and after booting to TWRP then format data then install twrp

Hey,
Thanks for your reply! I currently don’t have twrp on my phone but I could look at it. Do you have a link for MSM tool as download and possibly a guide?

You actually boot into TWRP it does not have to be installed,, you install it once you boot into it plus you would probably need a otg because you do not have a OS . Here's a link to the Msm tools
https://onepluscommunityserver.com/list/Unbrick_Tools/OnePlus_7_Pro/Global_GM21AA/
There are several great write ups on how to use and install msm tool right here in the op7p forum I will see what I can find and post later
