Can you explain what exactly were you doing ?!

Just hold the power button for 60 seconds or so, it should reboot normally. Did you flash twrp or just do fastboot boot twrp?

I'm new to this while A/B partition. I went through all the steps and my phone is rooted, with Magisk and TWRP. All seems to be fine. My question is this. When I boot to the recovery (TWRP) and choose the reboot option it defaults to Current Slot: Partition B. If I reboot to partition B it goes back to TWRP. I have to select Partition A to get the device to boot to the system.
Is this normal? Do I need to set it up in a different way?

i was trying to root the phone (wich i did) and then the twrp app that was on my phone after i had tried to install it using the img. it then turned into an ap that told me to update it in google play
after that was done i tried to flash it but everytime i tried it just crashed. a little time later after trying some more times i found that i started it in the bootloader and it ended up with me stuck in a bootloop. again i might not have explained enough. i am huge noob so i really need help.

discord
ignore the "discord" title. i dont think the phone has an OS right now. when i turn it on it goes directly to twrp. if i reboot the system it just goes back to twrp recovery. i think i need a way to install an OS (preferably OxygenOS if that is even possible). i realised that you guys properbly won't msg on discord. you dont have to. you can use the forums . i just really want help to get my phone back up and running. it is a OnePlus 6 btw if that is important.

To keep TWRP as the phones recovery, you'd first need to do as you did "Fastboot boot twrp" but that command will only allow you to boot into TWRP through your pc or whatever you ran that command on. After you've entered that temporary recovery, you'll need the TWRP installer .zip file, and flash that inside of that temporary TWRP. Then you can reboot into recovery on your phone again since it has been installed to one of the partitions.

You have to flash magisk after flashing twrp or else you are going to get this bootloop you are talking about

phone open again
my phone is back up and running again. i changed the partitian slot from A( the broken one with no OS) to B(the unchanged one) and it is now working again. if anyone is having the same problem the try to change to the second slot. it happend in twrp enchilada 3.2.2-0 if it is important. thank you all for your support.

I may be mistaken but I believe all you need to do is flash magisk to get up and running again

Why? You should be able to just flash the TWRP installer into TWRP and so its flashed into both boot_a and boot_b. It should boot ok to system from there, Magisk is just another mod to the boot partitions, like a custom kernel, etc. It should not be necessary at all, why you guys keep sayin Magisk is necessary for anything? it isn't.

Because you do. The OP6 will not boot with custom recovery unless it's rooted. I believe this is because the recovery and boot partitions are merged on this device. You're welcome to bootloop all day if you don't believe us.

Asking "why?" is not to not believe you, and the personal bootloop all day attack is out of the matter. TWRP is flashed on the ramdisk and should boot stock, unless something derped, if it doesn't boot I honeslty don't understand why, what is the exact reason? TWRP installer doesn't overwrite the boot, just patches it to have a mini recovery on it. It should boot...

I don't know for sure either, beyond what I said above. But everyone who has reported not flashing magisk has bootlooped.
If I sounded snippy, it was only because your post above was appearing to deny the reality of what is a very well-known issue with this phone.

I am not denying anything! just surprised because on TWRP website they clearly state that no post-twrp-flashing step is needed:
https://twrp.me/oneplus/oneplus6.html
The OnePlus 6 uses the newer AB partition scheme first introduced on the Pixel 1. As such there is no recovery partition. Instead, the recovery is part of the boot image. You will temporarily boot TWRP to perform and later perform a more permanent TWRP installation. First download the TWRP zip file directly on your device. If you don't download the zip file to your device first for any reason, you will need to adb push the zip to the device because MTP is not currently working on the OnePlus 6 in TWRP. If you are unable to use adb, you can also use a USB stick with an OTG cable, if you have those handy. Power off the device. Hold volume up to get into fastboot mode. Run this command on your computer: fastboot boot twrp-3.2.1-0-enchilada.img
In TWRP, tap on Install and browse to the zip and install it (the zip will probably be in /sdcard/Downloads). TWRP will now be installed to both slots. TWRP is now installed and you can reboot and use your device as normal.
MTP is disabled because it causes a kernel panic sometimes with the stock kernel.

Maybe the issue here is that the unofficial TWRP that everyone used NEEDS magisk while the official doesn't?

I think most people have moved to the official version. If it doesn't need magisk to avoid a bootloop, that's news to me. Not saying it's not the case, but I haven't seen any mention of it.

Help! bootloop after flashing twrp and magisk

Put into download mode and just flash TWRP with Odin, leave Magisk alone until TWRP is successfully installed. You can install Magisk from within TWRP afterwards.

and with twrp in place what do i do? to find and flash fresh system? it would be the best if i could somehow get to pin screen and decrypt data normally..i messed up big

SOLVED
i reinstalled twrp and flashed custom los system

One Plus 6 Bricked

Basically, I was rooted with magisk and had TWRP installed. I was on OOS 9.0.8. I tried to install the zip for 9.0.9 but i accidently wiped everything and dont have a backup. Now, my phone boots straight into the bootloader and I can't even turn my phone off. What do I do from here help please?

I have the same issue, nothing but bootloader, no os, no recovery.
Help please.

If you can get into bootloader, just flash the fastboot zip. It will wipe all data though. Just check in the the following thread

Stuck in "Bootloader unlock screen"

Hi,
i have TWRP installed with Magisk and ElementalX, everything was working fine, i just got an update for "google play system update" which i had to install.
I did that, but now i'm stuck on Bootloader screen which then boots into Fastboot Mode after a minute. Holding volume buttons and power does not help.
I still have following files that might help:
TWRP installed and the zip file for TWRP(which is still installed and working)
zip file for older version of Magisk
zip file for ElementalX
Is there anything i can do with TWRP or fastboot to keep my current files?
I assume my boot.img is missing due to that update?
I was running the latest OOS version.
Thanks in advance

Did you have any magisk modules installed before the reboot? If so delete them in TWRP data/adb/modules

First of all thanks for helping me, i did have 1 module installed vyper4android, which is already removed.
Also when i switch from Slot it goes past the bootloader screen but its stuck on the loading oneplus logo.
If it helps this is the current folderstructure: https://pastebin.com/xMWeW1uk.
Should there not be a build.prop in there?

Sounds like your Data is corrupt , if it wasnt it would def boot on a different slot.
I would suggest copying your data from your phone and make a back onto PC when phone is booted in TWRP.
Once done, wipe data only in TWRP , phone should boot.
Sorry wish i knew a better solution, been through myself a few times. Good luck:good:

Thanks for the info, i'm backing up my data as we speak but i prefer to wait for perhaps another persons view to see if a complete reset can be prevented with a lesser aggresive approach.
Thanks for your time though, have a nice day!

Question Pixel Experince and TWRP

Have a nice day. I tried installing Pixel Experience. The installation went without any problems, the system is fast without any stuttering. Phone calls without problems, the problem is with the sound of the ringtone and the sound is distorted in games. And that's why I wanted to go back to the original EU-ROM from xiaomi. But there was a problem while recovering from TWRP. TWRP says cannot recover data from internal storage. I had TWRP set up fine. After rebooting into the system, TWRP is still loading me, I don't know what the problem is.

You must have done something wrong.
Factory reset your phone with:

Don,t relock the bootloader.

I did all this and did a clean install via MiFlash. But I was confused by the error after the flash, the red error field was lit on the right in MiFlash. But the ROM booted without any problems. After that I did a factory reset just to be sure. All ok, installing TWRP as well. However, in TWRP it shows me data without internal storage. This means it won't load on app refresh and nothing from internal storage. I don't know where the error really is.

The error is normal since you don't lock the bootloader.(mentioned in my tutorial)
It was useless to do a reset after Miflash had done it.
Details on which rom and TWRP?

No problem on that side.
Try security on the lock screen to see if TWRP asks you for the code to decrypt.

I'm already reinstalling everything including TWRP. Otherwise, TWRP never asked me for a decryption code, but in the phone settings it is written that it is encrypted. Apparently that's the mistake. I'm doing a clean install. If the mistake wasn't that I did a factory reset after installing the ROM.

Factory reset just erases your data.
After installing the TWRP, reboot on the twrp and do not put any security on the lock screen.

I just installed the ROM, in phone settings I see - phone encrypted. I did not provide any security.

You can try:
TWRP
wipe/format data type yes(if errors ,red lines,reboot twrp ant try again).
reboot twrp
flash a recovery rom
check if still the same.

ok I will try

I did as you wrote no error in TWRP nothing red. After installing TWRP, it's a mystery that TWRP won't boot automatically, I have to boot it via hardware buttons. However, the phone still lights up encrypted in the ROM. It's interesting.
