One plus 7 pro, European version
So i was running Lineage OS on my phone for some time now (latest base update i did was to ob1 as far as i am aware), when there was an update lately
I installed it as normal, but the phone would not get past the boot animation and kept restarting, so i went back to the other slot to see if that still worked, but it only had a laggy boot animation, which never booted
I then installed the previous version that i was running before the update back to the other slot, hoping it would solve the problem of not booting (that worked before already) but it still did not boot
I saw someone post they had 10.3 installed as base so i restored the ob1 installation with a fastboot rom i still had on my hard drive, but upon finishing the phone just went into crash dump mode showing
dm-verity device corrupted force dump
kernel_restart
I tried another install just to be sure, but same result
I then tried flashing twrp to the boot partition to at least get there, but the phone just went straight to fastboot upon doing that
Fastboot boot still seems broken and just shows
D:\Minimal ADB and Fastboot>fastboot boot tw.img
downloading 'boot.img'...
OKAY [ 1.228s]
booting...
FAILED (remote: Failed to load/authenticate boot image: Load Error)
finished. total time: 1.346s
I searched around if there were other ways to install twrp from fastboot, and found this tool (https://forum.xda-developers.com/an...g/apk-img-dat-br-one-click-decompile-t3886057) that promises to unpack and repack the boot.img, so i hoped i could use that to manually add twrp to it, but it failed to unpack the file
Next thing i found was this MSM tool post (https://forum.xda-developers.com/oneplus-7-pro/how-to/msm-tool-guac-t3934691) instructed to hold volume up and down for 5 seconds before connecting the phone to a pc, and the program actually picked it up, however the phone started itself after a few seconds and went back to crashdump mode
At this point i'm seriously out of ideas, does anyone else have other ideas that i missed?
Does anyone have a boot img with twrp?
keep trying the MSM tool. it WILL work.
if you can get into fastboot again, type in fastboot reboot edl in ADB

This is indeed what typically shows for an error when fastboot boot isn't working. Probably due to using an older fastboot ROM. I'd try to use a newer fastboot ROM, or you can flash a patched boot image, which is how the phone was being rooted before fastboot boot was fixed:
https://forum.xda-developers.com/on...isk-patched-boot-image-oneplus-7-pro-t3964345
If I recall correctly, you can't fastboot boot with android 10.

Hi everyone!
I unlocked the bootloader (with fastboot oem unlock)
I booted and went through the initial setup
I went back to the bootloader and ran fastboot boot twrp.img
I get stuck on a black screen saying "Fastboot Mode"
The fastboot command outputs
Code:
creating boot image...
creating boot image - 10240 bytes
downloading 'boot.img'...
OKAY [ 0.007s]
booting...
OKAY [ 0.073s]
I have tried twrp versions 3.2.1-0 and 3.2.2-0.
Any ideas why I get stuck and twrp never starts up?
Try re-downloading the TWRP image again and try.

I tried verifying the .img files against the signature from the download page and the signatures didn't match, I guess I should have checked that before posting here. I must have fudged the downloads somehow...
I tried downloading again, now the signature matched and I could boot it. Thanks!!
This happened to me, I ended up flashing the most recent unofficial TWRP with fastboot and it booted into TWRP then I flashed the official TWRP zip from internal storage and it worked.
Need some help here as I am in a bit of a bind. Was on 5.1.11 and attempted to update to stable Pie. Used Blu_Spark TWRP v2 and upon rebooting got the error about device being corrupted. Continued booting but was stuck on boot animation. Rebooted to TWRP and attempted to restore nandroid. Upon restoring and reboot, boots immediately to TWRP. Attempt to change slots (which might have been an error on my part) and rebooted. Now stuck in fastboot! I attempt to flash TWRP.img via fastboot and get the following error:
Code:
PS D:\OnePlus 6\adb> fastboot boot twrp-3.2.1-0-enchilada_official.img
downloading 'boot.img'...
OKAY [ 0.628s]
booting...
FAILED (remote: Failed to load/authenticate boot image: Load Error)
finished. total time: 0.650s
If I try and switch to slot _b, I get the following error:
Code:
PS D:\OnePlus 6\adb> fastboot --set-active=_b
C:\Android\fastboot.exe: unknown option -- set-active=_b
PS D:\OnePlus 6\adb>
At the moment, my phone is bricked, so any help is GREATLY appreciated.
Thanks!!!!

I had the same, fixed it using this: https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665
Choose the Andriod PIE fastboot rom.
After that you can boot into PIE again, and if you want to go back to Oreo, use this Rollback procedure

Hello guys, as we known that it is unable to use command in fastboot to boot into TWRP if we are on Android 10 (both OOS and Custom rom) at the moment, so here is the simple command allow us to do that if you want to roll back android 9 or any rom by TWRP
fastboot flash boot_a <twrp name.img>
fastboot flash boot_b <twrp name.img>
fastboot reboot
Your phone will automatically boot into TWRP, so you can flash another rom
Can anyone confirm this works?
I tried something similar when I first installed OOS 10, and I successfully booted TWRP, but I ended up getting a bootloop (stuck at the g.co/ABH warning thing) when I rebooted to system. I don't know if I did something wrong, or flashing twrp to both boot partitions caused it.
I would try again, but I'm on a critical work trip until the end of the month, so my phone's uptime is expected to be 100% until then.
worked for me while anything else didnt

Does it wipe your data?
Didn't work for me. My boot image was patched already this is probably why.
ok, I tried this, but as reported above, now also stuck on this same: "I tried something similar when I first installed OOS 10, and I successfully booted TWRP, but I ended up getting a bootloop (stuck at the g.co/ABH warning thing) when I rebooted to system. I don't know if I did something wrong, or flashing twrp to both boot partitions caused it."
How do I resrore operation for my phone? (help?)
Well, I met this issue before, and ended up with using this method to successfully boot into twrp.
This issue seems to appear on OOS, when I using `fastboot boot xxx.img` on other ROM like omni, I'm able to boot into twrp, thanks!
can someone help me please. my phone is stuck in a fastboot bootloop. everything I try doesn't work.
fastboot boot TWRP.img NOTHING
tried your solution above and still nothing
Still stuck in fastboot this is what I get:

@killathenoob Download DECRYPTED OOS 10.3.0 with this help if you don't really know what to do with this.
For others people (and you if you want to root or just install TWRP after fresh OOS10 Decrypted install) don't forget to OEM unlock before doing anything.
Download this
Copy "twrp-3.3.1-17-enchilada-installer-mauronofrio.zip" into internal storage of your OP6
Power it OFF
Power it ON in fastboot mode
Launch "Boot TWRP.bat"
Connect your OP6 to your PC and wait for TWRP to boot
Install twrp-3.3.1-17-enchilada-installer-mauronofrio.zip
Reboot to recovery and install magisk if you need to.

Hope I helped a bit.
Hello,
I followed the steps on these two links:
https://forum.xda-developers.com/pixel-3a-xl/how-to/how-to-root-pixel-3a-3a-xl-twrp-t3928868
https://www.**********.com/unlock-pixel-3a-bootloader-and-root-pixel-3a-3a-xl/
To root my Pixel 3A. I unlocked it successfully, and then I did the final step of this command:
fastboot flash boot magisk_patched.img
But now my device is stuck on the bootloader screen. The bottom lines say:
Device state: unlocked
Boot slot: b
Enter reason: error boot prepare
I tried the options on the boot loader (rescue mode, recover mode, restart bootloader, powering off and restarting) but it only takes me back to the bootloader screen with same error.
From my MAC, I can still do the commands:
fastboot reboot (which does reboot the phone)
and
fastboot flash boot magisk_patched.img, which shows this:
Sending 'boot_b' (29136 KB) OKAY [ 0.760s]
Writing 'boot_b' OKAY [ 0.189s]
Finished. Total time: 1.219s
But not sure what else I can do to get out of the bootloader screen
Any help would be appreciated, as the phone is effectively bricked

Sounds like your magisk file is either the wrong version or corrupted. Download the full Google image, extract the boot.img from that and ash that image file using the fastboot flash boot boot.img command. Alternatively you could download the mvk kernel from here on xda and flash that. It's pre-rooted.

Thanks for that.. For whatever reason the MVK_Sargo_v10.22_magisk_patched.img version did not work, but the MVK_Sargo_v10.21_magisk_patched.img one did!

If 21 worked but 22 didn't... Going from my faltering memory that means your not on March security, your on feb or earlier. 22 only worked on March, i am running it myself.
I got stuck here, too... I used the flash tool (flash.android.com) and it put me back to stock after about a 20 minute progress bar crawl
I have the same problem can someone help me?
YYa solucionaste ?
Oneplus 6. Working just fine. OOS 10.3.2
So, I... got a new second phone for, well just because.

TWRP.img works! Have used on phone 1 and phone 2. today.
I need to boot to TWRP, get new OS installed (OOS current 10.3.2) and then... well, onward and upward.
