So, long story short I recently decided to try and root my oneplus7t I unfortunately made some mistakes and somehow corrupted some files. I read elsewhere in the forum that I could download the stock rom which I did and then use flash-all and that would allow me to go back to the factory settings so I could lock the oem and just go back to normal because I was tired of the headache. Unfortunately, after using flash-all I locked the oem thinking everything should be stock and it would work properly. But it says device is corrupt and trying to unlock the oem says oem unlocking is disabled.
So did I just completely brick my phone? I don't know of anyway to fix it at this point :/.

Can you still boot into bootloader via the hardware keys, whatever that combo is on the 7t?
Boot to bootloader or recovery and factory reset it or so.

I can get to the bootloader but it's Device State -locked and when I tell it to boot into recovery it says the device is corrupt. When I use fastboot to oem unlock it says I cannot, and I can't flash when oem is locked either.

Try
fastboot erase userdata and
Fastboot erase cache
Let me know if that works or not we will move on. Probably won't work since it's bootloader locked
You may have to contact OP and while you're at it, get the MSM tool for us all :good:
It says erase is not allowed in locked state . I think this is probably all she wrote for this one. I think I'm just going to send it back tbh, the whole reason I was trying to root it was because it didn't work with Sprint like they said it would. and I was wondering if I could find a way too make it work with custom software. Thanks for trying

I unfortunately no longer have Twrp installed as I did a flash-all with a stock rom already . If I try and flash recovery it says "flashing is not alllowed in lock state". Sideloading wasn't functional back when I had twrp either as the functionality for it is still in progress.

I ended up needing to flash the fastboot 10.0.3 firmware and was able to do a local upgrade to 10.0.4 that way, then flashing a patched boot.img via fastboot
I can't run any flash commands as my oem is locked. I don't suppose there's anyway around that?

How did you flash twrp with it oem locked??That doesnt make sense
I had twrp on it when the oem was unlocked, I was trying to reset the device to stock, so I did a flash-all and then oem locked it. But for some reason the repair was unsuccessful, and now it says my device is corrupted and I forgot to turn on oem unlocking in the settings on my phone after the flash-all before I did the oem-lock.

I cannot flash anything. Because my OEM state is locked.

Looks like you will need the MSM tool to fix this issue. You'll have to contact OP support and they will remote in your PC, load their software and flash it 100pct back to stock.
Also, disconnect them before they can delete the MSM tool so we can have it here in the community

Press volume up/down and power, reboot to fastboot. Unlock bootloader again. Install update from settings, reboot and install it again. (local install)
Factory reset in setting, reboot fastboot, lock bootloader. Reboot and untick unlock bootloader in developer settings.
Don't know if it's too late but I believe there's a working MSM tool now

Hi all,
I recently picked up a new Pixel and was wanting to flash it. I ended up enabling USB debugging and set OEM unlock within Android settings.
Yet when I use fastboot flashing unlock, it keeps telling me that OEM unlock isn't set. In my haste, I ran flash-all with a new Google build and this overwrote the existing ROM, but left the bootloader intact it seems. Now when I boot, it says I have a damaged OS and I should use recovery. The problem is that even recovery is damaged and it keeps rebooting to the bootloader. So adb won't work either. The only thing that works is fastboot.
Is there anything I can do to fix this or is it completely bricked? I can't seem to use fastboot to flash any ROM to the device - keeps erroring. I tried to match a ROM with the bootloader but that didn't work either.
Any ideas?
I used Nexus Root Toolkit when I got semi-bricked.
Use erase Command on flashboot for data and system then do flash_all again
As was mentioned, if you have fastboot you are ok. You can flash as mentioned above or use this -
https://forum.xda-developers.com/showpost.php?p=70611434&postcount=78
NRT is good for people like me who barely know what they're doing, enough to get bricked in the first place like I did. What i like is that it takes away a little of the uncertainty about whether I'm using the right files.
I hadn't rooted and unlocked and done all the setup in about a year so I forgot everything.
Save yourself some trouble and look at the "TWRP bootloops" thread. It's easy to avoid if you follow some specific steps, frustrating otherwise.
Thanks all, but will this even work, given that the bootloader is still locked? I have no way of unlocking it via any fastboot commands. That's why I am completely stuck.
Will NRT do that somehow in a way that fastboot can't? If so, I'll go find a windows machine from somewhere (who still uses Windows!?)

Won't work IF bootloader is still locked. Try this command > fastboot continue
That will work with locked bootloader, but not sure if it'll solve your problem. Nothing to loose by trying...

Yes, you can unlock bootloader from fastboot.
Um...
fastboot oem unlock
Learn fastboot. It's your friend!
btw, you don't need it unlocked to flash the stock image!

Yeah didn't think NRT would work because of the locked bootloader! Fastboot continue just gets out of fastboot - what is that gonna solve? I have a damaged set of partitions it seems - going from bootloader -> recovery boots back to the bootloader so it's clear that partition is damaged.
Is there any way I can just push some build to rebuild the partitions or can I do absolutely nothing until the bootloader is unlocked. And if so, how on earth can i unlock it if the only thing that works is fastboot?

I'll try that tonight. FWIW, I know I copied the line from flash-all to just flash recovery.img and even the system image, and both failed.
The only difference I see between that and yours is you have '-w update'. Maybe that's the trick.

You don't need that. I actually unlocked mine without it. The tool also has a unlock feature. Its worth a try.
Look for this forum post: flashing to stock android npd90g twrp t3424863
This helped me too. Only difference is I had TWRP installed.
Try unlocking bootloader via termjnal, then use the fastboot command via terminal (pc) fwtool vbnv write dev_boot_fastboot_full_cap 1 to reenable fastboot, then erase the partitions manually as mentioned in the tutorial and reflash them either manually or together using skipsoft / nrt or manual commands and a factory image.
Normally there should not be anything wrong with your bootloader image since modifying it is disabled for bootloader locked devices. Let us know about your progress.
Oh, also never flash an older system image than your current one.

Did you try:
fastboot flashing unlock
Since you only relocked, you unlikely toggled "OEM unlock"?!
If it fails, I think you are SOL. Maybe someone with a proper solution will chime in. Otherwise, you have to RMA your device...

Hey... Go into recovery and perform a factory reset.
Reboot bootloader and flash stock firmware. You could flash both slots to be sure your device is completely clean.
I wrote a how-to for someone having another issue. You.can follow this:
https://forum.xda-developers.com/showpost.php?p=71849370&postcount=28
When you are finished with flashing, reboot to be sure your system boot properly and your phone works as it should...
From here you can reboot into bootloader and issue:
fastboot flashing lock
If It was me I'd leave it unlocked though... Or at least OEM unlock enabled and ADB debugging ON. Since Google tend to release messed up OTA, you can always unlock the bootloader if needed.
But if you wish you can also disable the OEM unlock.
Good luck...

Hey...
You boot into bootloader when the Device is powered off
Just like in your video: with power + volume down
You can see infos regarding:
Bootloader
Radio
S/N
DRAM
Boot-slot=
Etc...
This is the bootloader :good:
From here, unzip the google image you have downloaded, open the folder and from here run the flash-all script. Let your device reboot. Power it down, boot into bootloader again with power + volume down. Change active slot as I described in the link I gave you previously. Run the same flash-all again... Done!
Just for safety, remove your Google account before you continue. You'll add it again later...
Good luck...

It could brick installing an OTA or whatever. Better restart 100% clean. :good:

Just flash the flash-all, relock and call it a day. Then you'll be fully stock and locked. I would however recommend rebooting once before locking to make sure its all good.

This happens because your bootloader has been unlocked at one time. There is no going back, even if you use "fastboot oem lock" later.
Edit: Just noticed the part about your device will not boot. You need to find the system image and flash it. I read somewhere today that OnePlus just released the system image for 4.7.4.
Can you unlock again?
@op, IMHO the best possible solution will be to flash stock rom image and stock recovery if required but I think when you flash stock image it will also flash stock recovery.
When you turn off the phone and boot it with VOLUME UP plus POWER, this should send you straight away to Fastboot. Try if you can unlock again, otherwise... bad luck - you'll need a restore session with 1+.

After looking into it further, I agree with you. That's what I get for having a bootloader-locked Samsung device for two years. I must be getting rusty!
Yes, the bootloader can be re-locked. There may still be a tamper flag as with previous OnePlus devices. But having a locked bootloader with non-OEM software would likely cause the problem he is describing. So, he needs to flash the factory image from bootloader.
I've requested to 1+support for restore remote session
Support send me file link and l2 will assist me in within 2 days
DO NOT RELOCK BOOTLOADER UNLESS U READ UP FIRST!!!!!, its worth just waiting the few seconds after reboot, then to go and try to relock the bootloader

Hi,
Like the title says, my Pixel XL is bootlooping.
The only thing that works is getting to bootloader, I can't even get to recovery without it booting again. The biggest problem is that it's OEM locked and obviously I can't unlock it via developer options.
Is there any way to unlock it without booting to the OS?

OEM unlock must be toggled before unlocking bootloader or CMD won't work, Can't you flash stock OTA in the recovery? https://developers.google.com/android/ota You can sideload the zip and should flash it to save your device once you get into the OS unlock your bootloader and avoid a situation like this again

Hey, if you can get into the bootloader, there's a high chance you can use fastboot. Using a computer to install adb/fastboot and then using the command line to run
`fastboot reboot recovery` (without the ticks)
Worth a shot, but if you can't get into recovery, I'm afraid the recovery might be failing as well.

Hi everybody,
yesterday I tried flashing the stock pocof3 rom back onto my phone, but since it got stuck in a bootloop at the fastboot logo. Showing the poco logo for a milisecond and then straight to fastboot..
(before this I flashed twrp and the arrowOS recovery and images a few time trying, without succes, to install this rom)
Last thing I did was flash via the mi-flash tool and did't see the "clean and lock" selection so it's also in lock state again.
I cant get adb to find the phone although the mi-flashtool is finding it.
anyone any tips?
I tried the vol up power trick, but this didn't help, keeps loading into fastboot

I tried sideload flash, miflash, copying update.zip to internal storage via ADB, and many other options - all without success).
- if your POCO is under warranty in your country (i.e. not a chinese import)... contact Xiaomi Support they can re-flash correct ROM
- Ask your local phone repair store... they *might* be able to flash original ROM back by using "Chimera" engineering software.

I'm not sure, but you may still be able to flash official ROMs.
But in "Configuration" make sure Erase is disabled

this doesn't seem to be an option. there is a checkbox with "erase all" but all are already unchecked

- Bootloader was re-locked whilst a custom ROM was in the phone.
(MIUI with Locked bootloader will not boot up where ROM is not stock or does not match the region/product code).
You cannot apply for bootoader unlock because you cannot boot up into Android and request the unlock via Developer mode.
You cannot remotely (via PC cable) flash any ROM into a Xiaomi / POCO phone whilst botloader is locked.
You are in a chicken and egg situation.,,, but if you find a way to repair your phone, please let us know how you achieved it.
Good luck!
If the system hasn't booted up yet there is a chance that you will be able to unlock bootloader again. Try it.

That's what I'm thinking too ...
Connect the phone to pc and do the bootloader unlock again via the mi unlock app - you don't need to apply again and stuff as long as you're able to recognise the phone inside app correctly

thanks everyone for all the replies!
tried unlocking it via the mi unlock tool (latest) but it says (in chinese) its locked by nr 123***456 by searching the phone - can't unlock
edit:
google lens translates:
X The phone has been locked by the account number 661****647 by searching the phone, Can't unlock
but it's not the nr. of my account..

Is it not even possible to flash Official ROMs?
Isn't there like a system that it checks the signature of the ROM and if it's a signed ROM it allows the flash? Or am I mistaken?

Nope bootload locked = no 'remote' flashes via pc
Apparently there is an 'authenticated user' mode for Xiaomi engineers in MiFlaah and also an EDL Emergency Download Mode which you can trigger by shorting out 2 pins on the motherboard so bypass bootloader lock and flash any ROM
Neither were available options for me

I also tried to simulate a local OTA by copying update.zip to internal storage using ADB push command and booting into recovery mode to flash ... But it doesn't work for me

I'm now in the procedure to sent it back under warranty. any idea if this is possible and what the cost would be if not under warranty?
If all fails i'll try the shorting by pins, should be interesting
I think a warranty repair claim is your best bet ... I have never read anywhere that unlocking bootloader invalidates Xiaomi warranty (Unlike Samsung and so many other brands!)
If warranty repair is re refused try a few independent repair shops
Last resort is get the back cover off the phone and short out the EDL pins
Good luck!
Let us know if you manage to get your phone booting up again

[Solved] Stuck in fastboot with locked bootloader
HI there! After multiple problems with the custom ROMs I tested, I finally decided to go back to the stock ROM by downloading it from the official thread. I extracted the .tgz archive, run the "flash_all.bat" program, which failed by saying it...

I once hardbricked (complete blackscreen, not even Fastboot reachable) a Poco F3.
I requested a replacement from Amazon and that worked.
I said a software update bricked it.
Of course having to do that is really bad, but I was scared of opening the back.
