I wanted to upgrade my LineageOS version, so:
I wiped all the partitions I could wipe (from TWRP)
I rebooted to recovery, but I got a CrashDump error
I tried "fastboot boot" the latest official twrp img, and the bluespark one, but same error.
I also tried this https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665 but it wasn't of help.
What do I have to do?
Both system and recovery mode leads to a CrashDump mode
Solved! I did this https://www.getdroidtips.com/unbrick-oneplus-6/ and worked!
If you can boot into fastboot, you could just flash fastboot images with flashall.bat script

I have wiped system partition and dalvik cache without flashing recovery and rebooted it, now I'm stuck on fastboot mode, anyway to boot back normally, without losing data? I'm unable to boot into twrp through fastboot, it says that couldnt authenticate boot image
Try switching the recovery partition, then try to boot the recovery img again.
fastboot --set-active=b
fastboot boot path/to/your/recovery.img
Bootloop to fastboot after being on dp3, and restoring carbon. I tried fastboot boot twrp.img, but it fails....I also tried fastboot flash it, it does, but still reboots to fastboot. Any suggestions?
I assume you had TWRP installed when this condition occurred, and trying to boot TWRP just sent you to fastboot?
What was the exact error message when trying to fastboot boot TWRP?

It sends the file...then I get a remote error. I tried fastboot flash too. It completed, but still boots to fastboot. Guess msm tool is needed. This phone is a pita.
I cannot get twrp to boot.....Phone refuses to boot it. WTF???
Have you tried this specifically?
Code:
fastboot flash boot recoveryname.img
I was stuck in fastboot yesterday after doing a TWRP restore. The issue was I did a backup and restore including boot and system/vendor.

LOL...Um, yes.
Use the All-In-One Tool and flash a fastboot firmware zip (you can find downloads in the software itself). After flashing your back on OOS and can use fastboot to boot TWRP again, then install or restore your rom
Hi everybody,
I tried to update my OOS to Android Q while keeping magisk, there was probably a module not compatible that I forgot to remove before and I could not access the interface after rebooting.
Trying to restore the stock boot.img with fastboot, now I am stuck on the "Boot Loader is unlocked" warning page and the phone refuses to boot.
I tried to wipe everything using fastboot -w but still can't boot normally, if anyone can help me solve this please, I would be grateful.
Regards.
Try flashing the unofficial TWRP for Q from here
You can follow that guide but don't install Magisk, then after successful boot, try flashing Magisk uninstaller in TWRP.
Can try flashing android 10 boot.img from #2 link.
this happened to me. It was because I had the usb pluged. If you take the usb out it will boot. Or at least mine worked that way.
What I did was completely restoring the device by flashing a fastboot ROM then updating to Q again. SO I've lost all my data.
Do you know any way I can root android Q actually ?

If you have access to fastboot then you can flash twrp and do below steps exactly else you will stuck at bootloader warning message
Reboot to fastboot mode. Flash TWRP img using the following command--> Oneplus blocked fastboot boot command
Code:
fastboot flash boot twrp-******.img
From fastboot mode, reboot directly to recovery mode. Now you have a working TWRP. (If you already have Magisk earlier, flash Magisk uninstaller now before proceeding to the next steps)
In TWRP, flash the stock boot image in boot partition. Don't reboot .
Flash TWRP installer zip then reboot to recovery. You now have a fully working TWRP in OOS 10. . Don't reboot .
Flash Magisk v20.1. Reboot to system.
restoring a TWRP backup is successful, but on boot the phone locks up with this error.
dm-verity device corrupted
"kernel_restart"
it will not continue. i still have TWRP installed. but cannot restore.
i tried running the following commands with no change
fastboot oem disable_dm_verity
fastboot oem enable_dm_verity
any ideas?

Can you boot TWRP still? If so, restore Data ONLY, flash full OOS zip version the backup is from, twrp installer, reboot twrp, flash full OOS zip again, TWRP installer, reboot twrp again, flash magisk and other mods you have/had/want. If you can't access twrp, use fastboot ROM to restore your phone.
Merry Christmas guys,
I have a really unusual situation.
First time that I have tried all tricks I know and I can't get myself out of this difficult situation.
I was trying to update Magisk with a patched boot file and after a reboot I was not being able anymore to access the system but only this black screen with the Crashdump Mode is appearing.
I can access the Fastboot screen, but no way to reboot to the TWRP recovery or to flash another boot.img, even through some pc flashing utilities.
Is there anything to try through another slot or something else?
I also tried:
fastboot flash boot_a boot.img
and I get this error:
FAILED (remote: Flashing is not allowed for Critical Partitions)
But my bootloader is unlocked and other commands like fastboot reboot works normally.
After I flashed through fastboot the images of boot, abl, dtbo, fw I can only access the TWRP recovery where everything is decrypted.
Any other ideas?
Try booting temporary into TWRP by using this command
fastboot boot twrp.img
If you can't use MSMDownloadTool
