download a recovery image file, boot into fastboot and flash using the fastboot command.
Once you have your recovery you can flash superSU
command: fastboot flash recovery recoveryFileName.img

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.

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:

Hi and thank you.

I tried reformmating sd card in FAT32 in windows but still same error.

"What step it say error?? " - If I understand question, I get the error int the step where you say "-reboot to recovery and instal the firmware from sd.."
Are u using twrp or not?? - "I'm trying with stock recovery. I also flashed twrp, and it recognizes the the sd card, but from what I understand I can't flash firmware from there, I have to use stock recovery."
"What model your device?? Z00LD or what?" - Yes its a Z00LD.
I tried adb sideload for flashing the firmware but it throws an error "can't read <file name>.zip".

Ok..try using this method..
-extract boot.img,recovery.img
-put rom on sd card
-enter fastboot mode
Enter this command
-fastboot erase boot
-fastboot erase recovery
-fastboot erase userdata
-fastboot erase system
-fastboot flash boot boot.img
-fastboot flash recovery recovery.img
-reboot into recovery
-try instal rom from sd card
-format factory device
-dont forget to pray for successful..
Im using this method when i got bricked while flashing pre rooted rom..i just can enter fastboot mode and i do this method.. good luck!

Thank you,
It worked. Phone is back alive.

Congratulation ..

Bricked ZE500KL, please help!

olá @jpof88, qual foi a versão utilizada??
tenho um que continua aparecendo o mesmo erro:

fez flash da system.img?

[ZE500KL] Long wait after 'fastboot boot boot.img'

After a failed root I've recieved the error ' Can't load invalid boot image ' . I tried booting ' boot.img ' . That didn't work . After I tried booting it I got to the ' Asus , In Search Of Incredible ' waiting screen . After that , nothing else happened , and it kept loading . Will it load eventually or is it not working ?

Did you root by flashing SuperSU with the latest twrp?

I attempted to root it using this : https://forum.xda-developers.com/ze...guide-marshmallow-root-guide-ze500kl-t3380461

Try to flash the latest twrp3025 image found on this forum in fastboot mode, if you follow the steps correctly, your're bootloader should be unlocked. Then try to boot in twrp/recovery and flash any custom ROM, 13/14 based.
Edit: Can you access stock recovery?

Can you flash TWRP without your device rooted ?

I doubt I can acces that .

You can flash twrp as long as your bootloader is unlocked. Go tk fastboot and type
fastboot oem device-info
If you see "Device unlocked: true" it means bootloader is unlocked!

I'll try and unlock it now

I unlocked it . What now ?

After unlocking it , the error disappeared , but I'm still stuck in the Asus logo loading screen

Flash the latest twrp, custom ROM and GApps.
---------- Post added at 20:11 ---------- Previous post was at 20:05 ----------
I think you dont have a ROM installed that's why its stuck in asus logo. So you need to flash a ROM

I am downloading the latest firmware ATM and I am going to flash it . What is GApps tho ?

If you want to flash stock ROM(from asus website) you wont need GApps. You need to be in fastboot if you want to flash stock ROM, but I can't help you since I never revert to stock before. But there are many guides here for flashing stock, be sure to read the OP Thread and the comments for more info.

The ' Android is Starting ' thing popped up and I'm freaking out that it might work finnaly ..

It worked ! Thanks alot dude !

Congrats in bringing your phone back to life. Haha

You need to unlock bootloader first then flash twrp and then root, otherwise twrp don't remain installed if you're not rooted
