Help! OP 6t McLaren 9.0.12 won`t boot into system after Magisk update /uninstall

Hi everybody,
I have a OP 6T McLaren, Oxygen 9.0.12 and I tried to uninstall Magisk 18.1 and update to Magisk 18.2 canary and something went wrong. After flashing I got the following error:
!Unable to unpack boot image
---
Updater process ended with ERROR: 1
Error installing zip file `/sdcard/Download/magisk-uninstaller.zip
The same error when I try to flash any Magisk version.
Phone doesn`t boot into system now. I can fastboot into TWRP and access files and folders.
Thank you very much in advance for your help.

Flash the magisk uninstaller then reboot. Then flash magisk.

I can't flash magisk uninstaller or magisk. It gives me the above error.
Even if I flash twrp installer in temp twrp it installs without error but after reboot it boots only in bootloader.
What can I do now to get the system working again?
-flash stock boot.img (where do I get file for McLaren 9.0.12?
-use MSMdownloadtool from here?

Try
Reflash OOS 9.0.12
Flash twrp
Reboot recovery
Flash magisk
Reboot system
Backup your data
Sent from my OnePlus6T using XDA Labs

Mclaren uses the same stock restore image.

I've been there format data .my friend let's his SD card encrypt or get errors on top of letting twrp (wrong version won't decrypt data either) if you do that reboot in system make sure adb is on and oem and auto updates are off

use different twrp the test build works better I had problems with orginal TWRP too

Solved!
All I had to do was flashing stock boot.img to boot_A and boot_B. Now It's working again...
Thank you very much for your help.

Ah.. Stuck in exactly same situation. Did you unzip the stock rom and flash boot.img through fastboot? Or did you take any different steps?
Niks.

Yes, unzip and flash both files via fastboot.

Just a note.
When installing Magisk and TWRP; I always install Magisk in one slot and reboot. I then use a partition backup tool to grab the stock boot image.
I then flash the stock boot image so the phone is completely stock again.
At this point I go through the TWRP and Magisk install the normal way.
I do this so I can always flash back to stock.
I also don't care about retaining TWRP or root.
I just start all over. It takes a few minutes but I don't usually have issues.
I also local install the same ROM to both slots before I install anything.
This way the opposite slot will always boot with the same version of the ROM.

Always boot in recovery mode after an update

Hi,
I was updating my OP6T to the new version (Magisk + Xxx NoLimits), but after the reboot post-update the device started to reboot to recovery after it booted. So I've tried to delete Magisk but the problem was still present, so I've decided to download the latest Oxygen ROM from the OnePlus and flash it from TWRP, but after flashing, the device started to always boot to recovery (before the OnePlus boot animation).
At least i tried to restore a nandroid backup of 1 month ago (System, Boot and Data), but still the device after the restore still boot to recovery before the boot animation.
I've only tried the system reboot (I've not tried to force boot another slot).
Do you have a solution to try before formatting the internal storage?
Thanks
Edit: After unistalling magisk and reflashing it again, now the device boots again, but immediately after (when the lock screen appear) the device reboot automatically to recovery again

Try this:
- in twrp , dirty flash the rom you are using (Oxygen os)
- factory reset
- flash twrp (the latest the better)
- flash Magisk 19.1
Reboot to system.
If this not working, Format data will work.

1. Boot into TWRP and Flash the Latest Magisk Uninstaller
2. Flash the latest Full Oxygen OS Zip
3. Flash the TWRP installer Zip
4. Reboot to RECOVERY to make sure TWRP stays and continue to root.
5. Flash the Latest Magisk to maintain root
6. Reboot System and Enjoy the latest firmware without any data loss

I am guessing you skipped the first step...
Try this:
Flash the OTA zip
Reboot (you will be unrooted and with stock recovery)
Boot to TWRP through ADB
Flash magisk unistaller
Reboot
Boot to TWRP through ADB
Flash OTA zip
Flash TWRP
Reboot to TWRP
Flash magisk

I don't have the OTA but the full rom, isn't simplier to update with the full ROM?

Ok, I've done this and actually is even worse, the device started to boot in recovery again and TWRP doesn't recognize that the internal storage is crypted, so i can't even access the internal storage (it shows only strange folders), so, now I can't flash the nandroid backup anymore.

I also mean FULL rom .zip.
Format data in twrp or in Fastboot. Or use MSM tool .
https://forum.xda-developers.com/oneplus-6t/how-to/tool-6t-msmdownloadtool-v4-0-oos-9-0-5-t3867448
all of them will wipe ALL in youre phone, but it will work.

So I've to Full wipe and then adb sideload the ROM? Because at the current state I can't even boot the device, it always starts in TWRP
Edit: I've also tried the blue_spark's version but nothing changed, TWRP can't recognize the encrypted storage

you can try this first.

When you're saying you're flashing the full ROM after wiping, are you meaning the xxx no limit? If so this isn't an os rom it's just a magisk module rom that's an add on to oxygen os. You need to wipe and flash the latest oxygen os rom, stable or beta which ever you're using, then flash TWRP, flash your os again on the other slot, flash TWRP, flash magisk, if your system boots fine then flash the xxx no limits rom in twrp.

No, I flashed the full ROM downloaded from the OnePlus server

Have you tried formatting data?

You're best bet is to use the MSM tool

Ok, I've decided to use MSM to recover the device, I've lost the internal storage, but at least the device is working again.

Maybe it was a Magisk module that caused it. I removed pixel module from Magisk and it done the same to me.

Need some help - Strange OP6T storage issues after flash

Hello, I have a T-Mobile 6T which thanks to the XDA thread about bypassing T-mobile, is running the international firmware so I didn't have to kiss their butt trying to unlock the bootloader. Yesterday I decided to try the Resurrection Remix rom since it is unclear whether the Lineage 16 rom supports the in-display fingerprint reader, and I am too busy at work and too lazy to read the entire thread to see if it does.
I followed the instructions and updated my OxyOS to the latest .15 release via TWRP which I also updated to the latest version via OTG using a USB drive because I was unable to unencrypt using the older Blu-Spark TWRP version I had installed. After the OxyOS update (on both partitions) I flashed TWRP again, rebooted to recovery and installed Pico Gapps.
I found the Resurrection Remix rom to be very buggy and I hate the way the in-display biometric works (very slow and I don't like the paw print used as fingerprint placement). Anyway I started installing apps and after 4 apps installed, it says there is no space left in storage.
Nothing will update, and when I try to check storage with any file explorer it says "access denied" or just won't load. I've tried everything. Wiped the data and did factory reset, then flashed stock rom again and same issue. What am I doing wrong?

That looks like a messed up flash. And is pretty common. Considering that A/B is still new and everyone has his own method of flashing. So assuming you can make it back to latest Stock OOS (9.0.15 right now). If you dunno how to then simple reboot to recovery, flash OOS ZIP and then TWRP. Again Reboot to Recovery from within TWRP (Reboot -> Recovery) and again flash OOS ZIP and TWRP Installer. For TWRP I recommend you to grab the latest one (3.3.1-6 as of now). Once flashed, Format Data (Wipe -> Format Data -> YES) and Reboot. Wait for it to boot up. Now you should be on Stable Stock OOS with TWRP Installed.
Now Download ROM of your Choice (RR, LOS, Bootleggers, whatever). You will also need the latest TWRP Installer (same as above) and Gapps (Nano/ Stock Recommended) and Magisk if you want to Root. Reboot to Recovery, flash ROM ZIP and TWRP Installer ZIP. Wait for it to Finish. Reboot to Recovery. Once in TWRP, again flash ROM and TWRP Installer. Once done, again. Reboot to Recovery from Within TWRP. (Read above on how to). Now, flash Gapps. Magisk if you want to Root. Once done, again do a Format Data. Reboot and be patient for ROM to boot. And then tell me wether this works or Not. Good Luck.

Flash custom ROM

From 6T (purchased from oneplus.com), any time I follow the instructions for how to flash one of the custom ROMs, I get stuck at the bootloader with no working rom.
I was able to use the MSMTool to restore to 9.0.13. I upgraded a few times flashing OnePlus6TOxygen_34_OTA_024_all_1909112343_9fd6e0057b8747dc, which works, but when I try to flash a custom ROM, I cannot get past the bootloader. I say a few times because I've tried this for a few days now with no success.
Most recently, I used the Flash-all.bat inside 10.3.0-OnePlus6TOxygen_34_OTA_042_all_1912142031_d9ef3-FASTBOOT
I am currently on 10.3.0, with twrp-3.3.1-31-fajita-Q-mauronofrio installed using the fastboot flash boot_a twrp-3.3.1-31-fajita-Q-mauronofrio.img then fastboot boottwrp-3.3.1-31-fajita-Q-mauronofrio.img commands from fastboot.
I can then install Magisk 19.4 or 20.3, however again when I try to flash a custom ROM, I cannot get past the bootloader.
What am I doing wrong?

When you 'fastboot boot' twrp, you can't flash twrp as .img file after that..... (There is no recovery partition on our phone, only a boot one)
If you flash a twrp img it will overwrite boot partition with only twrp and no kernel... Basic knowledge. Once temporarily booted in twrp by 'fastboot boot' command you must flash the installer, meaning the .zip file.
Then reboot your phone in twrp and flash whatever you want
Always latest versions of Magisk, why flashing a deprecated 19.4?

I was having an issue with the boot command in 10.3.0, which is how I found the flash command, and using both of those seemed to work (at least get me into twrp).
Now I am able to just run fastboot boot twrp-3.3.1-31-fajita-Q-mauronofrio.img and it works.
I was using 19.4 because somewhere in here someone mention twrp not working with magisk 20.3.
I've had no issues with 20.3 and twrp, so I will continue to use 20.3
The steps I use to flash a custom ROM (after twrp is installed)
1. remove the lock screen security from the existing ROM
2. boot straight into recovery from the existing ROM
3. wipe Data, Cache, and Dalvik by swiping right to factory reset from the wipe menu
4. flash the ROM from internal storage using the Install button
at this point I've tried a couple of approaches including a reboot here to see if the ROM flashed, and also installing twrp right after flashing ROM so that I will have a working twrp install.
Either way, I can never get past the bootloader.
Am I performing these steps correctly?

I don't know I don't flash custom ROMs anymore, too old for that stuff and need my time for me.
There are specific instructions for each custom ROM it's better to ask in dedicated threads, some of them need to have OOS in both slots before, some of them need to be fleshed in both slots. Normally you eventually wipe things, flash the ROM and twrp to keep it, then reboot to twrp (necessary to boot on the slot where the ROM is actually fleshed, which is always the non active slot, which become the new active slot) and flash Gapps and Magisk ( because Gapps and Magisk can be flashed only in active slot) then reboot system

I've updated these instructions here, they are the same, just added to them really.
This is how I install Lineage 17. (If you are doing 16, replace 10.3.0 with 9.0.17, and the Q image of TWRP with the Pie image)
- Install 10.3.0 fastboot ROM again to start over, boot it once. Just to make sure everything is good.
- Reboot to fastboot.
- Boot the Q image of TWRP.
- Run the TWRP installer, reboot to recovery
- You backed everything up right?
- Factory reset (This is the slider at the bottom in the wipe menu).
- Format data. (This is the button that says Format data in the wipe menu)
- Do NOT wipe cache, do not Wipe system, do NOT Wipe Dalvik / ART, do not add anything else, Just Factory Reset and Format Data. After doing those two Reboot to Recovery one more time. You must do this after formatting data.
- Now transfer Lineage and TWRP to your phone, Windows / Linux should see TWRP fine as a media device when plugged in.
- Install Lineage
- Run the TWRP Installer.
- Reboot to Recovery.
- Install Lineage (You need Lineage on both slots, so yes run it again)
- Run the TWRP Installer (yes again).
- Reboot to Recovery.
- Install Gapps if you want them.
- Install Magisk 20.3 if you use Magisk. I used 20.3 it works fine. (20.4 also fine) Do not install modules or other add ons at this point. Boot once and go through the setup and everything, then install your add-ons.
- Be aware the phone will restart once, then Lineage will start up and all will be good.
From that point on updating should just be like normal :
- Reboot to recovery
- Flash Lineage.
- Flash TWRP Installer
- Reboot to Recovery
- Flash Gapps. (Assuming you use them, if you installed them once you must continue to install them or do a clean install)
- Flash Magisk. (If you use it)
- Reboot to system.
- No loss of data, or anything.
- No need to flash anything twice etc.
I've posted similar instructions here. It was just for LOS 16, same thing essentially though.

Sir, apology for being an old noob, I am on OOS 10.3.2 TWRP 3.3.1-32 can I follow the above guide? If Yes,
Why aren't we using the "Lineage Recovery" provided in "Lineage OS Downloads" page?? If we use it, will the above instructions change ? What are the cons of using it?
Sorry again for asking!! Can you please share me the Link to Open Gapps which Will be suitable in my scenario ?

Historically Lineage / CM recovery was hit or miss, or TWRP or other recoverys worked better. To be fair I haven't even tried the Lineage recovery. So maybe that is no longer true? Right now, I know TWRP works. The updated instructions link up there has links in it, FYI, link OpenGapps. OpenGapps can be found here. You will be using Arm64, Android 10 obviously.
Since you are already on 10.3.2 (I assume you were on 10.3.1 before) you should be good to skip the step about fastboot ROM or install OOS, and you already have TWRP., so you should be able to go right on to backing everything up, wiping everything, and installing Lineage. (So you can skip the first few steps)
Anymore questions feel free to ask.

First of all, thank you very much for your time and explanation.
Sir, so i will proceed as follows:
* Boot into TWRP Recovery
* Perform "swipe to factory reset" & "swipe to wipe data"
* Reboot to TWRP recovery again
* Flash LOS 17.1 on slot A
* Reboot to TWRP recovery again
* Flash LOS 17.1 on slot B
* Reboot to system
Sir, please check are my steps correct? If not,
From which step( steps mentioned in your guide) should i start?
Last query is, which GApps zip will be best for me, micro/nano/pico/tv stock, If i want max coverage of google?
Very sorry for knocking you repeatedly!!!

Your starting point is correct. However make sure you don't miss the re-install TWRP after flashing Lineage each time, and the second time you need to flash Gapps before you reboot to system.
Personally I always do Nano. Anything else you need (that would be included in Micro) can be installed from the Play store. Nano at least includes all the things that can't be installed from the play store.
Pico has the least in it. TV is for TV devices. On OpenGapps there is a box next to each package you can click and it will tell you exactly what is in each package.

Sorry for the necropost, but this also works for TWRP 3.6 and Lineage 18.1. I initially had a problem with the default TWRP for my 6t. During the initial TWRP fastboot the version on their site caused a firmware error which I could just barely get out of, but it screwed up the system boot process in some subtle way that even the fixed version of TWRP (found on this site) couldn't solve.
After trying your instructions above, it didn't work the first time because of the screwed up system boot. It just kept trying to boot to recovery. I suspected a firmware error and was almost going to do an mcmdownload soft-brick rescue. I tried one last thing, using the TWRP on the system to sideload the stock ROM. That worked and patched up the system boot process. Once I booted and ran through some basic initialization to make sure developer options were properly set I followed the above instructions and it worked nearly flawlessly.
One strange thing. After I installed Lineage 18.1 and TWRP to both partitions (as well as Gapps / magisk), it rebooted to system and almost booted without incident -- except a large circular logo popped up that said 100% and stopped. I figured that that meant someting completed properly, so I powered off, waited 10 seconds, powered on and then the Lineage green system initialization spinner came up for a few minutes and it went through the user initialization sequence.
Thanks. I almost gave up and bought a new phone.

- Install 10.3.0 fastboot ROM again to start over, boot it once. Just to make sure everything is good.
- Reboot to fastboot.
- Boot the Q image of TWRP.
- Run the TWRP installer, reboot to recovery
- You backed everything up right?
- Factory reset (This is the slider at the bottom in the wipe menu).
- Format data. (This is the button that says Format data in the wipe menu)
- Do NOT wipe cache, do not Wipe system, do NOT Wipe Dalvik / ART, do not add anything else, Just Factory Reset and Format Data. After doing those two Reboot to Recovery one more time. You must do this after formatting data.
- Now transfer Lineage and TWRP to your phone, Windows / Linux should see TWRP fine as a media device when plugged in.
- Install Lineage
- Run the TWRP Installer.
- Reboot to Recovery.
- Install Lineage (You need Lineage on both slots, so yes run it again)
- Run the TWRP Installer (yes again).
- Reboot to Recovery.
- Install Gapps if you want them.
- Install Magisk 20.3 if you use Magisk. I used 20.3 it works fine. (20.4 also fine) Do not install modules or other add ons at this point. Boot once and go through the setup and everything, then install your add-ons.
- Be aware the phone will restart once, then Lineage will start up and all will be good.
From that point on updating should just be like normal :
- Reboot to recovery
- Flash Lineage.
- Flash TWRP Installer
- Reboot to Recovery
- Flash Gapps. (Assuming you use them, if you installed them once you must continue to install them or do a clean install)
- Flash Magisk. (If you use it)
- Reboot to system.
- No loss of data, or anything.
- No need to flash anything twice etc.
I've posted similar instructions here. It was just for LOS 16, same thing essentially though.

OhioYJ, these are great instructions but it initially left me with questions about how that procedures would create duplicate installs on slot A and B. The answer is of course that the Lineage installer for the 6t knows about the dual slot setup and always writes to the inactive slot. Booting into recovery activates the inactive slot so that installing again after that installs to the other slot and now you have Lineage on both slots. The installer for TWRP always installs to both slots and is needed because Lineage always installs its recovery handler and you don't want that so you overwrite.
PS: TWRP has an option for installing itself after installing the requested package. Would that be just as good as installing the TWRP zip?
PPS: I had to do an 'adb push' of the Lineage and TWRP zips to sdcard for the installs. Unfortunately installing and slot switching makes the sdcard unavailable so you have to push the zips again. Is there somewhere I can write them to that I don't lose access to after a boot to recovery?

Mi9T stucks on kali boot logo after flashing nethunter

I do have orangefox recovery flashed into my phone. Wiped data, system, cache... and format data
First of all, I installed MIUI (the latest version from mi website "miui_DAVINCIGlobal_V12.1.4.0.RFJMIXM_e0ac13ed89_11.0.zip"). If I reboot into the system, it works fine.
Then flash magisk(v24.3) and 'disable DM-Verity_ForceEncrypt', and reboot into recovery
When I flash nethunter (nethunter-2022.2-davinci-miui-ten-kalifs-full.zip), which I downloaded from offensive security webpage., it does install well (at least it doesn't show any error messages).
After flashing nethunter, I rebooted into system. When nethunter logo did pop up, it got stuck into that fire animation. I can still access fastboot and recovery menu.
Any idea of what's happening? Why doesn't it boot?

For Magisk you ABSOLUTELY don't need Verity and so
Simply, extract boot.img from the firmware zip and by using Magisk APP take install, Select and Patch to patch your extracted boot.img
Do not enable Recovery option while patching
Then flash from Fastboot the patched boot img to Boot
That's it - the proper way to install Magisk to your Xiaomi ( I used and still use on my Mi 9T from MIUI 10 till now with MIUI 12.5)
For Nethunter I cannot help you. It's been more than two years since I used Kali and at that time it installed flawlessly.
However, then I had MIUI 11 and Kali required MIUI 11 - don't know how is it now...
And btw, I always use the latest TWRP.me version - currently 3.6.1_9-0
