So when i try to fastboot the bootloader .img manually, it says:
sending bootloader ... okay
'writing bootlader'.... failed (remote: (invalid state))
so what do i need to do to fix that?

Is your bootloader locked?

it said lock status: unlock
So i would presume its unlocked...

OK. I've never seen that error before. And a quick google search doesn't come up with anything either.
You could try restarting the bootloader with
Code:
fastboot reboot-bootloader
and trying again.
The only thing I can think of is you could be trying to flash the wrong bootloader (which i doubt) Just to confirm you are trying to flash bootloader-grouper-3.34.img
Also, to just unroot you don't need to reflash the bootloader. Just boot.img and system.img

Yes, I am trying to flash bootloader.grouper-3.34.img
And Im flashing bootloader because its I'm told to do in this thread? http://forum.xda-developers.com/showthread.php?t=1781250
I will try what you told me and see if it will work

So i rebooted the bootloader, and it still gives me the same thing. Whats the command to boot.img and system .img?

Both the boot.img and the system.img are in the image-nakasi-jro03d.zip you must extract them first.
Then run: fastboot devices (to make sure you're connected) if it returns the serial number then proceed.
Code:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot erase cache
fastboot reboot
This should maintain your data and unroot your nexus.
However, I am a bit concerned about the invalid state error. I can't find anything about it at all. I'm worried your nand might be corrupted and proceeding with this might lead to an unrecoverable state. Maybe someone else can weigh in on this... I don't want to scare you but I don't want to be responsible if something goes wrong.

hmm... I hope more people would weigh in on this? Cuz im exchanging the nexus 7 due to flickering screens, and im new to the rooting/unrooting stuff so i dont want to brick this device cuz im a n00b.

hmm... I hope someone else weigh in on this to help, cuz I'm going to exchange this nexus 7 for another 1 because of flickering issues...

Restart, carefully check

My nexus had the ghosting issue and I had to unroot my device to ship back today. Heres how I did it.
1. Download stock ROM from Google.
2. Unzip stock ROM from Google. The unzipped file will have 4 files in it. (Boot loader grouper image, flash all.sh, flash base.sh and the image.zip)
3. Unlock your device by clicking the unlock button on nexus root toolkit
4. When your device wakes turns on set it back up. No need to log into Google.
5. turn a dB back on in development
6. Click flash stock + unroot
7. click other/browse
8. For choice click I did this already.
9. Click OK
10. browse to your unzipped file location with the 4 files in it.
11. click OK
12. Done

Did you find a way to flash the Bootloader?
I'm thinking about a hardware issue as well. Are there any Devices, with corrupted NAND's known?

Pls Help Impossible to flash a new recovery img

So guys basically, I wanted to give F2FS a shot, I downloaded the recoveries that the thread told me to, flashed either of them using the fastboot flash boot filename.img
With both of them, and even the latest official TWRP I get this:
sending 'boot' (8182 KB)... OKAY [ 1.056s]
writing 'boot'... OKAY [ 0.182s]
finished. total time: 1.238s
and on my Bootloader screen I get the message FASTBOOT STATUS OKAY
So, you'd think all went fine.
Rebooting into recovery reveals that I have the exact same recovery as before, I've tried like 10 times and the result is always the same one

Are you sure the one you flashed is different to the previous one? Which recovery do you have now and which do you want to flash?

I have TWRP 2.7.0.1 and I'm trying to flash either KT recovery or the latest TWRP 2.7.1.0, I'll try flashing CWM and then change back to one of those to see if I can manage to do that

fastboot boot filename.img worked and I managed to change my filesystems, I'll try creating the zip as the recovery keeps going reverting and 2.7.0.1 isn't able to read my partitions now, I'll update with the results and so far I just booted up and everything seems to be going well.
Edit: Ok, I DL'ed an official TWRP 2.7.1.0 zip and flashed it, my recovery updated successfully, however it isn't able to read my /cache or /data partitions, next, I replaced the recovery.img with the exact same img I used to convert to F2FS (the one provided here) and again booted into the functional recovery through fastboot boot filename.img, I flashed the new zip file and everything seemed to be fine, rebooting to recovery shows that the original TWRP 2.7.1.0 wasn't replaced as I'm unable to mount the data or cache partitions.
Also worth mentioning that using the TWRP manager from the playstore to try to flash .imgs does not work either

The fastboot method listed above is to flash a kernel not recovery, if your trying to flash a new recovery you run
fastboot flash recovery nameofrecovery.img

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!

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

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.

Unlocked OnePlus 6T stuck in bootloader

Hello, my OnePlus 6T is stuck in fastboot mode, I'd like to install Oxygen OS (which I have the zip file on my PC) or install twrp on it in order to flash the OOS but here is the problem:
If I type the command fastboot devices, the phone is detected:

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
