Unable to flash TWRP (remote: dtb not found)

When I try to flash TWRP (via "fastboot flash recovery twrp.img" then "fastboot boot twrp.img") I receive the following error:
Downloading 'boot.img'
OKAY [1.477s]
booting...
FAILED (remote: dtb not found)
finished. total time: 1.534s
I've tried manually booting it into recovery with power button and volume down but it just freezes on the oneplus logo where I have to turn off and on again.
Any help is greatly appreciated!

I found the solution.
For anyone else with this problem

that link just saved me!

I tried this recovery (I had the same problem as the OP) but although I can boot into twrp, I get stuck on the oneplus logo if I try a normal boot?

I managed to get it working by flashing CM after flashing the recovery.

Next time, correct command is the following:
Fastboot flash recovery twrp.img
You tried to flash the recovery image onto the kernel/boot partition, luckily it doesn't allow this, unless it's an actual kernel image fitting that partition. ?

Actually, fastboot boot twrp.img boots the TWRP image without flashing it.
fastboot flash recovery twrp.img flashes the TWRP image to the recovery partition.
Both are valid commands and have their uses.
fastboot flash boot twrp.img would be the command to try to flash the recovery image to the boot partition and shouldn't be used.

Are you sure you flashed the correct OOS3 bootloader compatible version of TWRP? Latest official 3.0.0-2 should be compatible.

The bootloader (also called fastboot) comes with the original ROM. In your case you're already on the newer bootloader since you flashed OOS3 which means you will have to flash recoverys and ROMs compatible with this newer bootloader.
This TWRP should be compatible
https://dl.twrp.me/oneplus2/twrp-3.0.2-1-oneplus2.img.html
Also you can't run ROMs not compatible with this newer bootloader (which means pretty much any ROM that's not using the official Cyanogenmod source tree for building). That is except for OOS3 or newest HOS of course since these are made for the newer bootloader.
However I would say the error message you get might be caused by bad cable, faulty driver setup, faulty fastboot tool version or in worst case damaged partition layout on phone. The last one can be fixed by the Qualcomm OOS2 factory restore solution.

Hi, i am having the same problem.
some background: I was on Oxygen OS 2.x.x, i wanted to upgrade to Exodus 6. I had the older version of TWRP. So I tryed to install the new twrp image within twrp. When i rebooted i couldnt boot into twrp, receiving the same error message as in OP title, when using fastboot.
Using the tool all in one toolkit I was able to flash stock recovery.
But I still cant flash Twrp.
I can still boot into system though.
Any advice? Thanks.

That explains why you're having problems. You're doing it the wrong way.
First you must upgrade the bootloader by either flashing the convert to Marshmallow zip file which also installs the correct TWRP for the new bootloader (easiest way). Or you could flash the latest official OOS3, then fastboot flash the latest TWRP and from there format system and flash the ROM that's using the newer bootloader.

Does that Link work with oneplus x also? Having same problem as Higgings when trying to install twrp and cyanogenmod.

thnx a lot for sharing
:good:

[HELP] Recovery Bricked and can't reflash

Hello,
I've decided to install the Beta version of Oxygenos 3.0. Since my phone came from the OnePlus support, I've unlocked the oem, installed TWRP and flashed the Oxygen zip.
However, a day later I've spotted important touchscreen issues (I can't use the touchscreen sometimes).
To see if it is a software problem, I've decided to go to the recovery to reflash a backup. When I try to go to recovery mode, nothing Happen! (Just the oneplus logo ).
So, i've decided to reinstall TWRP by flashing it with fastboot.
"fastboot flash recovery recovery.img" -> OK
"fastboot boot recovery.img"
downloading 'boot.img' ...
OKAY [0.702s]
booting...

I've tried to install the stock recovery but I've the same error.
PLEEEASE HELP. I've waited a week to receive my phone because it had a problem but it's broke again :crying:
Note: I can go in Android normally (but with the touchscreen problem)

http://forum.xda-developers.com/oneplus-2/general/firstaid-zip-revert-h2os-mm-beta-to-lp-t3306967 try this.

This happened to me too except I would not boot into the OS or recovery. I ended up going into fast boot and formatting the System, recovery and data partitions. Here is what I typed.
fastboot format system
fastboot format recovery
fastboot format data
I am not sure if you have to format the data but I did.
After that I flashed TWRP
fastboot flash recovery recovery.img
Then I booted into recovery and was able to restore.

I've tested your manipulation and it worked well too.
For those having the same problem OR want to install Oxygen OS the CLEAN WAY, read this post before: https://forums.oneplus.net/threads/installation-instructions-faqs-oxygenos-3-0-0.439108/
It is very important to read the faq before flashing and doing **** like me.

OPT bootloop, no recovery, cant boot into twrp.

So i just saw the new Oxygen OS 3.1.0 is out in OTA form. Me being rooted i tried flashing it through twrp, which i had installed before. (i should also note that i had Xposed installed too, on Oxygen OS 3.0.2) now i think i might have gotten my zip file wrong and installed a previous version. The boot animation is the square, triangle and circle one. It just goes through my apps and tries to update them for eternity. When i try putting the device into recovery (power+vol down) it just freezes on the oneplus logo. I later discovered that i can use fastboot when in that mode. I tired flashing twrp but i couldnt boot into it. fastboot boot recovery.img didnt work either, giving me this:
downloading 'boot.img'...
OKAY [ 0.746s]
booting...
FAILED (remote: dtb not found)
finished. total time: 1.011s
Now i have no idea what to do. I'm sure I've made SOME kind of mistake along the way, but i cant find a way to fix this. I have a nandriod backup of just before flashing if that might help.
fastboot reboot-bootloader puts me in fastboot mode but it doesnt change anything.
also, ADB naturally wont detect the phone whatsoever.
Ill be very glad for any help! Thanks!

Are the drivers accurate? Does your PC recognize your device as it should in Device Manager? That's usually what I check first when I have fastboot errors. I think the only way to fix this is through fastboot... so I would focus on trying to get that to work first.

**** man. I'm in the same boat as of a few hours ago. I was having a ProxyController wakelock and the few Google results I saw told me I should reflash the modem. I accidentally flashed the old modem (OOS2, I believe). I can't boot into my rom OR TWRP. BUT fastboot does work. I also get the "remote: dtb not found" error when trying to boot from the recovery image.
As long as we have fastboot, we can always go back to OOS 3 using the various unbrick methods. I'm trying to avoid having to go through that whole mess of re-rooting/unlock the bootloader etc etc. I'll post on here if I'm successful.
Update: I NEED a functional phone so I just went and erased everything. Sorry I couldn't be of much help to you man. What I did:
I went here and downloaded the fastboot version of OOS3 and converted the bat scripts into bash scripts (I only have Linux computers near me right now...; the commands in that bat script are exactly the same as they would be in bash, I just had to rename the ".bat" to ".sh" and make it executable). I'm back in OOS 3 now, unfortunately. There IS a way mentioned on the page below that talks about how you can prevent userdata from being formatted, but I didn't really care too much. Hope that helps.

Phone stuck on Essential Logo (Powered by Android) screen while trying Oreo B2 OTA

I have tried everything to get this phone to boot up. I was downloading the Oreo B2 via OTA, not sideloading. While the update was installing, I went about my business. I walked away for a few minutes and came back to a phone that just sat at the boot screen. I let it sit for about an hour, thinking that was some how normal. After an hour, I hard powered down and it came back to the same screen. I have rebooted at least 50 times now with no luck.
I can boot into fastboot, but not recovery. If I try to go into recovery, it goes to the boot screen and sits there. I have tried to switch partitions, it is stuck on A, without luck. The bootloader is locked and I can not remote unlock it via fastboot. Nor can I manually change the boot partition to B.
I have an open ticket with Essential, but they have been blowing me off and basically told me I'm out of luck since I was in their Beta program. They told me to go to XDA. A$$wipes! Any help you can offer is greatly appreciated since I'm stuck with a bricked phone and having to use an old iPhone since I cannot be without a phone.

Exact problem happened to me last week and a very helpful XDA member saved me.
Just hook up phone to pc by adb, type in 'fastboot devices' (while in fastboot mode) and install 7.1.1 os again. You'll lose everything but at least you won't be softbricked anymore.
Edit: sorry, just read you do not have unlock bootloader so this probably won't work.

Have you tried wiping data in while in fastboot? That might get it to boot.

You don't need an unlocked bootloader to sideload the install (following the BETA instructions: https://www.essential.com/developer/beta-builds
Since you can use fastboot, it looks like you have working ADB environment, so you should be able to follow those instructions. The STOCK recovery works very differently than TWRP, so make sure you follow those intructions, particularly the "Apply update from ADB" part. It took me a while to understand this, especially because the type on the screen is so tiny, I couldn't tell any words were changing.

I'm having the same issue (stuck on the boot logo "powered by android" screen) and I can get into fastboot mode, however if I try to go into recovery mode it just gets stuck on the boot screen again.
When in fastboot mode, the device state is "locked" is there any ways to get this fixed?

You could try: (you will lose all your data)
fastboot -w
fastboot reboot

update im still stuckk

Have you tried booting to bootloader and mounting /system?

This is obviously corruption of the firmware, and has nothing to do with wiping userdata. Download the full firmware and flash all of it through fastboot.

I also have my phone stuck The bot is closed and I can not do anything

Unlocked OnePlus 6T stuck in bootloader

Well I don't really need to get in to recovery I just thought i could help install the stock rom, what I want to do however is flash oxygen os on the phone, and I don't know how to do it through fastboot

Are you a t-mobile user? You're supposed to use the flash-all-partitions.bat file in order to flash the rom... What exactly have you done up to this point and what files are you using?

No I'm not a T mobile user, where can I get the flash-all-partitions.bat and what do i need to do with it ?
What have I done to get stuck in bootloader:
I unlocked my OP6T with the ALL IN ONE TOOL by mauronofrio
Flashed the TWRP from mauronofrio
But when I wanted to reboot the phone I figured out I was stuck in fastboot mode: if I try to boot in the os it boots in fastboot mode and same thing when I try to boot in the recovery
I don't know what happened..

I'll try to follow this guide, thank you a lot for your help, If this still doesn't work I'll tell you

1. Download the full rom
2. Put your device into fastboot
3. extract the contents of the full rom zip file
4. extract the images and the other flash zip file as well
5. run flash-all.bat, if that doesn't get you to boot, run flash-all-partitions.bat.

Id post your issues in the thread he linked. Specific to your device , most guys here in this thread are on tmo and it's a bit diff for us.

Not recognized by the PC how? Are you trying to use the fastboot command? "fastboot devices" does anything come up?
You will need the fastboot ROM here, most likely to fix this.
Your last resort should be the MSMTool. (Remember it will relock your bootloader)

My Oneplus 6T is stuck on bootloop from 6 hours+ I've tried to hard reset the device, i have tried Volume Up + Power button, Recovery mode, deleting cache, none of it is working.
I had updated using the Oxygen Updater, 10.0 update, and it is now stuck forever in bootloop.
Please help
