I am stuck! Suddently my OP7P boots only into fastboot. - OnePlus 7 Pro Questions & Answers

The device is rooted. Running OOS 10.0.9 European Version.
Magisk 21 was installed and the device was perfectly running. No issues for a long time.
I wanted to open Magisk just a few minutes ago and then the phone froze and rebooted itself.
Now after the bootloader warning, it goes into fastboot.
I have no custom recovery. My recovery is the op stock recovery.
Is it bricked?
Can i save it somehow?
Please help.

Perhaps some how you switched slots kinda hard to diagnose this one

Wierd Bootloop-Problem when flashing TWRP

Hey Guys,
so i got a wierd bootloop problem and for now i didn't find any solution here on xda or somewhere else,
not even a thread where someone has the same problem.
I'll try to give you as much information as possible in a chronological order.
First of all I got the international model (G920F).
So like 2-3 months ago everything was fine, my phone was rooted, got TWRP working and was flashing Roms with no problem what so ever. TW-Roms like Noble Rom and also AOSP/Lineage OS.
One day I wanted to flash UltImAtE NoUgAt A8 Port and that is where the trouble began, dont think it has something to do with the rom but maybe it helps.
So i flashed the Rom(wiped everything except int. storage), flashing was no problem but it didnt boot.
I know first boot always takes some time but after about 20-30 min I forced a reboot (Power+Vol. Down for 7sec).
After that the phone got into a Bootloop(always rebooted into the "first bootingscreen")
I let this process happen for about 15 min. and then tried to enter TWRP via hitting the buttons between the boots which didn't work. I then did "force" a reboot(Power + Vol. Down) which strangely resulted in one final reboot and turning the phone off after the first bootscreen.
So with the phone finally turned off I was able to boot into TWRP and reflashed the rom but the result was the same.
I did the same procedure again to get into TWRP and flashed the Stock Deodexed TW Rom, flashing worked but then the Phone directly rebooted into TWRP. Rebooting out of TWRP or booting the phone from beeing shut down both resulting into booting to TWRP.
So to get my Phone working again I had to flash stock ROM which in my case is G920FXXU5EQDF_G920FDBT5EQD1_G920FXXU5EQCD via Odin.
That worked but of course root and TWRP were gone so I then flashed TWRP via Odin(both newest Versions at that point)
aaaaaand phone straightly booted into TWRP again all the time. I tried different combinations of older versions of both twrp and odin but the result always was the same.
So at the moment I am on Stock, the phone works which is nice but i really wanna get TWRP working again and i have no idea what to do.
I hope someone can help me with that.
Cheers Guys

You do know that if you flash TWRP, you need to use a kernel that has dm-verity disabled or you need to be rooted. Flash TWRP then Flash Magisk through TWRP

As it seems I did not, good thing that its written right at the TWRP download page...
Can't remember doing this when I installed TWRP first but as it seems I did.
Everything is working fine, just flashed Nexus OS and it booted.
Thank you so much dude

Latest Magisk messed up my boot. Can I recover without losing everything?

It isn't, I don't know what I'm doing. How do I fix this issue, where should I be

OOS11 Broke TWRP and bricked my devices

My Phone was running Android 11 perfectly fine. Has been for about a week and a half, and I've decided that I don't like the OS. I was going to flash a custom ROM and went to create a nandroid before flashing. Literally all I did was boot into recovery and TWRP got stuck in a bootloop, the TWRP splash screen appears, crashes and then reappears about 2 seconds later, now when I try to boot back into system, TWRP appears instead and continues to bootloop. I can enter fastboot mode but that's all.
So far I've tried
Booting TWRP through fastboot. Failed another bootloop.
Rebooting through ADB. Boots into TWRP.
Rebooting Bootloader. Seems to do nothing.
Does anyone have any ideas on how to fix this ? It seems strange to me that something as simple as booting recovery could do this much harm. I also have a nandroid backup stored on the device from about a month ago, so the data loss wouldn't be THAT major, but I'm also not sure how I could access it without system or recovery access.
Hi , Which version of TWRP use? I think there is an update a new version TWRP 3.5.2 , Try to flash it. if its still not booting try to boot the original Boot of OOS11.
May be this threads will help you.

New version does not work as well. Flash the stock boot img to get out of bootloop.

Phone bootloops only if Magisk is not installed

Hey, I recently got my Poco X3 NFC. I unlocked the bootloader, flashed a custom ROM and recovery, everything seemed fine. After installing Magisk (flashing the new "apk") from TWRP recovery, everything went fine too. Later I decided to switch to another ROM and I did a FULL wipe of pretty much everything except the stuff necessary to run the phone. I then flashed the new ROM and it got stuck at the yellow POCO screen, powered by Android and the padlock. I then rebooted back to TWRP and flashed the apk again, the phone booted with no problems whatsoever. The "Uninstall Magisk" button in the manager was completely broken, complete uninstall did nothing. I decided to uninstall it again from TWRP using the apk and renaming it to uninstall.zip. It successfully uninstalled, and after booting the same thing happened. Just stuck at the POCO screen. Then I flashed Magisk again, and it booted fine. I can't get my phone Magisk-free without it bootlooping. I tried flashing the stock boot.img, the ROM's boot.img, pretty much everything and nothing worked. Anyone knows what's happening?
same problem with samsung galaxy s8, and now it got worse on me after trying new rom, now my phone is stuck at recovery and doesn't work at all even the samsung repair center said the motherboard should be REPLACED, so I would recommend that you choose the most stable rom and keep it and stop changing your phone software or it will ne soft bricked like mine !
Alright, thanks. I guess I'll just keep the current ROM with Magisk. It'd be nice to have a phone booting without it though.

Oneplus nord root problems

So today I decided I wanted to root my nord, so I downloaded Magisk and a boot.img file but the boot.img was the wrong version. It installed okay at first. It rebooted and everything worked, but Magisk said that it hadn't been rooted fully and to restart, and this is where the problems began. I got stuck in a boot loop, so I went to recovery and factory reset it. When it was booted up, the wifi wasn't working at all. I restarted the phone and nothing happened, so I reset it again and had the same result. Then I thought to have a look at the files I used and finally realized that my boot image was two updates behind. I then got the boot image from the latest release on oneplus website and flashed it, but had the same result. The device is not currently rooted after I installed the stock image but wifi problems are still persisting. I tried relocking the bootloader, but it said my device is corrupt so it couldn't boot. So I unlocked the bootloader again and this is where I am now. Any advice/ help would be hugely appreciated.
