The same for me. Tried magisk 22 and after reboot all I see is fastboot mode. I'm trying to fix it using those images
Everything got erased. I flashed all partitions (using that flash_all.bat file)
Tried update via magisk manager. First update the manager. Then update magisk root via magisk manager. It failed to download something. When I rebooted it was only in fastboot mode. Tried to boot to recovery to uninstall it / install the zip file. whatever I did, I got stuck with errors. I gave up
Guys we are in the same boat, see my post here: https://forum.xda-developers.com/t/...stboot-loop-please-help.3866917/post-84553203
:-( did anyone of you reported this in the magisk github?
Any hints how i can recover it without wiping anything?

Have created an github issue for magisk to warn other users: https://github.com/topjohnwu/Magisk/issues/3924
@gartner @rafu997
Which fastboot rom do you used? "10.3.3-OnePlus6TOxygen_34_OTA_045_all_2004142152_e822ca326-FASTBOOT.zip" is the latest one created?
thx

I used 10.3.6-OnePlus6TOxygen_34.J.48_OTA_048_all_2010042240_dbd576b615-FASTBOOT
Running the bat file and all ok... and after setting up, I did an OTA update. all ok. Today I installed twrp and old magisk.. all ok..
I didn't have any problems with magisk update. installed update and reboot fine

The people it failed for, you hadn't hidden the Magisk Manager app right? Because you're supposed to restore the app before updating to 22.
I had it hidden. But I restored it before upgrading. But I did not reboot the phone after restoring it... Before upgrading. It may be the reason.. I don't know...
Yeah, I restored magisk before the update. After unbricking I wiped everything again, installed clean 10.3.8 ROM and tried flashing Magisk 22 with TWRP 3.5 but I lost wifi (couldn't turn it on) and I couldn't make any calls. Turned out that I had to flash TWRP 3.4, reflash rom and then Magisk 22 worked. I also tried Magisk 21.4 with TWRP 3.5 but the same issue with wifi and phone call so that was not a problem with Magisk 22 but with TWRP. Both 21.4 and 22 worked ok with TWRP 3.4. I don't know why.
Guys, i finally unbricked my phone WIHTOUT data loss.
See here for instructions: https://github.com/topjohnwu/Magisk/issues/3924#issuecomment-785751618
And yes, i had the Magisk Manager app hidden before, did the unhide process but also dont rebooted (maybe thats the issue?). Just straigth upgraded magisk to 22 and bricked it.
Hope this helps someone.

Thank you for this! @popy2006 @gartner
If I can't boot into twrp to follow these instructions, what if I was to use slot_a (its unused right now) to install oxygenos and twrp - could I then recover data?
@mauronofrio Does flashing a different version of twrp cause problems when decrypting the data partition?
Do you use the .img file instead of .zip file from TWRP?
I also could'nt boot TWRP image (.img) in the first time.
After hard shutdown of the phone (key combo) it magically worked (without chaning anything).
Try again.
Good luck.
Otherwise, maybe @mauronofrio can help.

Yes I used the img file for twrp 3.4, and every img file version on the twrp website, none of them booted up. I have restarted the phone via hard reboot multiple times, no change. Still stuck at fastboot.
Thank you @popy2006 I'd appreciate all the help I can get - there's several chapters of a novel I'm writing on the phone that I really want to recover.
I don't know the consequences of simply flashing a magisk patched boot.img to the boot partition, especially if it doesn't match the exact OS version that was installed (unfortunately I don't remember exactly when I last updated it). Wish I had another phone to test this on that didn't have irreplaceable data stored on it :/

Don't know why it's not booting.
I am trying my best to help you
Maybe just flash an unmodified boot in fastboot and retry to boot twrp.
I think an kernel is need to boot it, so just flashing boot should be enough.
Don't you know which OOS version you had?
I think the better it matches, your chances are higher.

124Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via recovery (either stock or twrp) because is no more needed. The updates will be done on the slot not used for example if you are using slot a the update will be installed on slot b and the slot b will be set as default. If you brick and you are in bootloop how you can restore the rom? You can't with Stock ROM you have, because the zip can be only installed via Update Engine, so what can you do? Flash a stock rom via fastboot. I have extracted all images from the stock zip and i have made a new zip with the Fastboot ROM with a flash-all.bat included. This will work only if your bootloader is unlocked. This will erase all your data and will wipe your internal storage.
HOW TO FLASH
This version is only for not branded devices
Download the zip;
Unpack the zip in a folder;
Reboot the OnePlus 6T in fastboot mode (Power and volume-);
Connect the OnePlus 6T to PC;
Run flash-all.bat flasher you need;
Wait until the process end;
The phone will automatically reboot.

MANUAL FLASH: Windows - OSX - Linux
If you want to manual flash these roms these are the commands (you need to extract images.zip before proceed)
Fastboot Partitions:
If you need also persist partition, this is the command:
Criticals Partitions, for these you need to boot the TWRP:
When you are in TWRP you need to run these commands to push and flash all criticals partitions:
REMEMBER
"Invalid sparce file format at header magic" is not an error, you need to wait a bit when you see that string, just wait.
These ROMs can't be used to update or downgrade your phone but just to restore your phone, so don't use them to come back to oreo or to update from oreo to pie.
If you want to rebrand your phone from HydrogenOS to OxygenOS you can follow this guide: Rebrand Guide

No worries, brother. Been there several times. But the real credit goes to the OP. Without his work, none of this would be possible [emoji869]76
Recently i made a new app to make the fastboot rom directly from the official rom, so actually the process is 90% automatized. When a new rom comes i still need of 1-2 days to download, make and ipload the fastboot rom. These depends from when the link of full rom will be released and if i'm at home or not.6
