Also I cant flash any OTA Roms. It will say unable to complete device is in lock state. My concern is . Is there a way to unlock the bootloader at this state of my phone or its completely garbage now. Sigh..

Did you make sure you enabled OEM unlocking under Developer options?
Is this a TMobile 6T or the international 6T?
You can always use the MSM tool to return it to stock / working form.

Hello sir thanks for responding to my concern. Actually this is not mine I just borrowed it. In the middle of browsing it just suddenly happen to stuck or hang up. Then when I tried to force restart its now showing the bootloader menu. So I dont know if the oem unlock was enabled. Sorry for my bad English

Go to settings
Developers option (if u dont find it go to about phone and tap 5-6 times on build no )
Then u will see the developers option in the settings
Enable oem unlocking and also enable android debugging
This is the main reason behind it oem unlocking is disabled

In the bootloader, what are the two lines under the green "Battery OK" line? Should be something like...
Device is LOCKED. Status Code: 0
Software status: Official
Also please attach output of 'fastboot getvar all'
its mentioned under battery ok line.
Device is Engineering

You can't unlock an Engineering status bootloader. Your device was repaired and shipped out incomplete, not the first one we have seen... You need to contact Moto support, there is a thread in the official forums about this bootloader state, it's kind of a partial unlock but it's uses for factory flashing in a different way than we do it.

Three UK and bootloader status

Is anyone on the Three network in the UK and have tried rooting or ROMming their phone??
I have been trying for a week now to access the bootloader (using 'adb reboot-bootloader') so i can use fastboot but the phone just restarts and boots up like normal. This to me suggests a locked bootloader.
After several calls to Three and an official complaint made, they insist the bootloader is unlocked yet when i went to the Three store the other day they say it is locked. Someone is lying!
Can anyone else on Three confirm if its locked or not??
All i want is to boot temporarily into TWRP and create a nandroid backup. Ive done this at work plenty of times yet I cannot do it on my own phone!! :/
You need to set the OEM lock to off in developer mode.

I have set OEM Unlock and USB debugging and still no joy.
Someone at Samsung told me my phone is locked but Three still claim its not locked.
I have been able to get ODIN to see the phone but i cant risk flashing anything as Samsung have told me they wont repair my phone if i do.
All i want to do is boot the phone with a temporary recovery. For that i need fastboot but i cant get fastboot no matter what i do. Its should be so simple!

Unlocking your device is failing because you haven't ever enabled Allow OEM Unlock or USB Debugging from within the OS. The only way you will be able to unlock the phone is to get it to boot into the OS first, and going into Developer Options to toggle these two settings on. You may be able to use the method linked above to briefly get your phone booted into the OS long enough so you can do this. If you are lucky enough to accomplish this, then you can disable the big cores using a custom kernel.

Thanks for giving the link. I checked it but in that links it showing the method to enable OEM and I am totally failed to boot into the OS. I got only Google Logo and it loop again and again. I tried fastboot flashing unlock but It showing me Remote: Device is locked.
Is there any way to installed the New OS or downgrade or repair current version with unlocked OEM Devices?

You have to try either of those two methods (extreme heat or extreme cold) to see if you can get it to boot even for a couple minutes. Neither method is quick nor do you have time to mess around once the phone finally boots. You can only upgrade with a locked bootloader. So you are stuck unless you are under warranty or can try the fix.

I'm at work so I can't watch your video. I don't recommend opening up a device if you aren't technically sound enough to follow whatever the instructions are. So, try at your own risk and loss of warranty.

Hey man, here is what I did though my device was rooted/unlocked/custom kernal (EX)
- Put the phone on charge
- Switch on, let it bootloop, eventually it booted [takes a day at times]
- Backup if you need to (eg. ADB pull).
- I have EX manager so I enabled power save mode which disables the 4 big cores. As long as the phone doesn't reboot or die no bootloops.

You will need to get into the OS somehow to toggle the dev settings. Otherwise you will not be able to unlock the bootloader. You will not be able to apply the fix (flash custom kernel) with a locked bootloader, and there is no way to unlock it unless your phone can boot. There are a few "tricks" to use with the heatgun/hairdryer that force the phone into limp mode so it will boot into the OS. Others have claimed that once booted, they have enabled "power savings" under settings>>battery and that prevents the phone from going back into the looping. Keep trying, and good luck with the hairdryer!

If it's a software issue best thing to do is completely wipe your phone. Easiest way is to install Twrp and wipe all incuding internal then flashing fresh stock image. I'm sure there is fastboot commands also to erase (or some other way if can't do neither.) This will remove every last thing from your phone so make sure if you are able to back up pics,docs,downloads,music etc. Last thing though don't think it's causes issues make sure your flashing the right version of February stock image Google finally labled them. Or March if it's out.

Hello, you describe a cluster A57 failure, to fix it you need to boot into your phone enough time to enable USB debugging and OEM unlock then flash a modified kernel or a modified ramdisk
See this thread : https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279/
To boot into your device you need to overheat the CPU so the software will shutdown the faulty A57 clusters to cool down the device as soon as it boot up enable USB debugging and OEM unlock before the A57 clusters goes online (because it will shutdown your device) once you succeed enable USB debugging and OEM unlock flash modified files and enjoy your working (but slower) N6P
I had that problem too, but wasn't able to live thinking that my phone was working with CPU issues, so I bought an other Nexus 6P from a guy on the internet, he was selling it because the screen was broken, I got it for real cheap ! I swapped the screen of my BLOD N6P to the one from the guy, it cost me 60$ to completely fix my phone (way less than buying a new phone or buying a new microprocessor)

Hy!
Already done that... Today It comes back from service, they told me they replaced the PCB ... so... it could be a hardware problem or a malware of some kind that ruins the memory... that's what i think about those problem, but i suspect google has something to do whit it!
So... i'll get back to you when I will have IT! :fingers-crossed:
bootloop can't unlock device
I have had exactly the same problem. I tried in vain using heat or cold to get the thing to boot, but independently found the method of leaving it on charge for a few days, occasionally it will get into the O/S.
So while in the O/S I enabled developer options and adb too (the second time) and unlocked the bootloader.
However it still claims to be "device is LOCKED" in recovery mode. This is really weird. I have also factory reset the phone but that hasn't helped.
Luckily I have read the other posts about power saving mode so I'll try that next, it will save having to flash a non-stock OS.
When people ask why unlocking the bootloader is important to me, this specific situation comes to mind. If you had unlocked your device you could have fixed this easily, mind you you would lose 4 cores.

*** I ran into a similar catch-22 issue on my 6P (H1511) the dreaded bootlooping with OEM Unlock turned OFF. ***
*** Couldn't flash the phone because OEM Unlock was off, and couldn't turn OEM Unlock on because it was bootlooping. ***
*** You MUST be able to fix the bootlooping/freezing at least temporarily, in order to turn on OEM Unlock in Developer Options ***
I have tried the "squeezing" method to no avail.
Then tried the heating method, which worked to a point where it has reached the color circles while booting, but then it started looping again.
I figured there's nothing to loose, so I cranked up the heat on the digital heating plate to exactly 140 Celsius for about 10 minutes covered with a paper towel, with only the upper half of the phone's back touching the heating plate (no need to "cook" the lower part with the battery).
It was still looping after the circles appeared, BUT by leaving it to cool off for about an hour, it has finally booted up into the setup page, so I quickly went to Settings > About/Phone/Software Info > clicked the "Build" line 7 times to enable Developer Options, under which I enabled OEM Unlock and ADB Debug.
If it's still bootlooping, you may try to "freezing" method where you would put the phone into the deep freezer for about an hour.
However, heating has worked for me.
Following that, in FastBoot mode I entered the following 3 versions of the flash unlock commands (only one will work out of the 3 which is fine):
fastboot oem unlock
fastboot flashing unlock
fastboot flashing unlock_critical
Downloaded the latest full stock firmware directly from Google.
https://dl.google.com/dl/android/aosp/angler-opm6.171019.030.b1-factory-ab13a98b.zip
Unzip it, and run flash-all.bat
Once the flashing has finished, DO NOT let it boot up, instead hold down the Volume Down as it's about to reboot, which will kick it into bootloader/fastboot mode.
I have tried flashing the Osmosis zip to patch the boot but it didn't work, it was still bootlooping.
So I have flashed a pre-patched 4-Core Boot kernel to fix the bootlooping issue permanently.
For Android 8.1 OPM6.171019.030 flash this 4-Core Boot with the commands below:
https://androidfilehost.com/?fid=13356325061477269711
fastboot flash boot Huawei_H1511_6P_OPM6.171019.030_Boot_4Core.IMG
fastboot reboot-bootloader
At this point flash a 4-Cores patched TWRP, go into TWRP recovery (hold down Volume Down + Power for 10 seconds, Volume Down to "Recovery", Power) and first "format" Data, then "wipe" Cache, Dalvik-Cache, and Data.
Note, all information on your phone will be lost by the above format/wipe operation.
All done, hope this method may help some of you.
And here are some interesting FastBoot commands I've come across....
C:\ADB>fastboot flashing get_unlock_ability
(bootloader) 1

Instead of "fastboot getvar all", you can also use "fastboot getvar <variable>" (without the quotes and <>)
Any <variable> from the log above, between "(bootloader)" and the second ":"
For example:
fastboot getvar serialno
Enjoy!
My nexus 6P recently went through this bootloop,
Google screen coming up and stuck there, for 5 days, i was going through many possible solutions throughout the web, but they all said it must boot to OS to be able to unlock oem bootloader,
Finally stuck at extreme heat or cold, extreme heat did'nt work for me, but YES extreme cold did actually work, i kept it in the deep freezer for about half an hour, and then waited 2 min, and plugged the charging cable and powered ON the phone, to my astonishment, it did start and i was able to use the phone.
I have rebooted several times since then, it works fine for certain time, and then crashes and restarts all the time, i can still use th phone but its uncertain when it will restart again.
I tried to install new custom rom, but it still says DEVICE IS LOCKED and i cannot do anything else.

Oneplus 6T qualcomm crash dump error, recovery not working

Hi,
I have oneplus 6T which has suddenly started giving qualcomm crash dump error after normal reboot. I have tried msm tool to flash. Tool shows success but when it boots the mobile at end , same crash dump appears again. have also tried multiple version of msm. Also visited service center but they are suggesting motherboard replacement.
Now i want to try manual flashing. Phone is in bootlocked state. also OEM is not unblocked. Is it possible tounlock OEM when my phone is not booting. also is it possible to change boothlocked state to unlock?
I can go to fastboot by pressing vol UP + DOWN and power button but on selecting recovery option it still goes to same crash dump state.
Please suggest what options do i have?is there any way to recover?
Thanks
If your device is a global model 6t then put it in fastboot mode manually then try "fastboot oem unlock* and see what happens.. Unlocking the bootloader won't fix a hardware issue but it won't hurt anything either. ?
Have you ever unlocked your bootloader and then locked it afterwards? If so I wouldn't recommend it again. I've seen a few people screw up their devices that way on here. I've never since Nexus S days when I began modding my phone's locked a bootloader. I always unlock and leave them unlocked.
**I'd either sell it as is online or get motherboard replaced then unlock bootloader and install whatever you'd I like but don't lock the bootloader after you unlock it. That's just my opinion. I've been on XDA a long time and had many devices over the years and I remember reading about people on 5 or 6 phone's I've had in my past screwing up their phones that way..

Thanks for responding
yes device is global model of 6T.
I have not unlocked /locked bootloader in past.
"fastboot oem unlock" gives error as "FAILED (remote: Flashing unlock is not allowed)"

Hi,
yes tried couple of older versions too (listed below).
ANDROID+10+OOS+10.3.5+fajita_41_J.47_200717.zip
ANDROID+10+OOS+10.3.2+fajita_41_J.44_200222.zip
6T_MsmDownloadTool_v4.0.59_OOS_v9.0.13.rar
Every time on completion of msm flashing in all the above versions, I still get qualcomm crash dump error.
My question is: Is it necessary for bootloader to be in unlocked state for msm tool to work? if no, is there any other command to unlock the bootloader on a bricked phone as "fastboot oem unlock" and "fastboot flashing unlock" fails with the message "not allowed".
thanks again for responding to the post.

As far as I know no. Because in order to unlock your bootloader you must have access to the screen so that after you send the unlock command you can use your volume buttons to confirm and power button to select yes and then it does its thing...

Hi,
The only screen i have access to is "fastboot mode " which has options like start, power off, restart bootloader, recovery mode.
When i choose recovery it goes back to same qualcomm crashdump.
i have tried sending "fastboot oem unlock" from pc while i am in fastboot mode. but gives error as
FAILED (remote: Flashing Unlock is not allowed

None of what I had typed will work because your bootloader is blocked correct?

Hi,
The only screen i have access to is "fastboot mode " which has options like start, power off, restart bootloader, recovery mode.
When i choose recovery it goes back to same qualcomm crashdump.
i have tried sending "fastboot oem unlock" from pc while i am in fastboot mode. but gives error as
FAILED (remote: Flashing Unlock is not allowed
)
finished. total time: 0.005s
Thanks

I think the only thing that may work would be a programmer box (ex: Octopus, Mudusa..) and I'm not even sure if it would or not. I was just about to buy two before this stupid Corona bs hit and made me broker than broke. If you had one of these programmer boxes I'm talking about you may be able to fix it but I'm not 100% sure of it and they cost anywhere from $75-300 depending on which one you're looking at. They make many different programmer boxes and they all are compatible with and do slightly different things.. Sorry I couldn't be of any real help man. I hope you can get this fixed.
I'm quite sure the reason you're being denied when trying to send the bootloader unlock command is because your switch in developer options on your device isn't switched to enable bootloader unlock.
yes you are right ... got same error
fastboot boot twrp-3.4.0-2-fajita.img
downloading 'boot.img'...
OKAY [ 0.678s]
booting...
FAILED (remote: boot is not allowed in Lock State)

thanks for your reverts .

Have you tried formatting data and then reboot system? I know that sounds kinda dumb but if I were you I would definitely try that. It might boot up to system. To do this you can plug up to your computer and open command window and manually set phone in fastboot mode where you see the "START" screen. Then from PC terminal do: sudo fastboot -w (hit enter) and then once it wipes , push power button on your device which should still be at the screen that reads START. Your device should then reboot. I'd give that a try for sure if I were in same situation.
What did the service center quote you price wise on motherboard replacement?
The process looks doable I think..
https://www.ifixit.com/Guide/OnePlus+6T+Motherboard+Replacement/129570
I'm assuming motherboard is the mainboard. If so OnePlus has the 6t main board costing more than I paid for my mint 8gb 128gb OnePlus 6t.

If you end up trying everything and just can't get it fixed ...
If the cost to repair is two hundred plus dollars I would sell it online as is and add some money to it when you can and grab another used device from swappa.com . I paid $200 for my 6t near mint condition on swappa about 5-6 months ago.
Hmm, unlocking the BL is a mute point if you didn't open the developer options and check usb debugging and oem unlocking... So as the phone is borked at moment, I like the idea of reformatting but I wouldn't reboot after the format.. but have MSM ready to go and use the edl tab in twrp to start the msm...flash away..
tried the format with -w,
erase-successful-but-not-automatically-formatting-cant-determine-partition-type........
looks like locked bootloader will not let me do anything

hi,
even though format didnt work tried with msm too after the command to format but same result.
formating throws error as

Well that's not good.. as flashing with msm wouldn't matter whether the bootloader is lock or not ... As it automatically relocks it anyways... Has me stumped..
Are you sure you didn't flash anything that wasn't specifically made for your model device? I mean after you started to fix the crashdump issue?
Want to hear something crazy.. Two days ago when we were first commenting about this crashdump deal, about an hour after we stopped chatting I took a shower, got out and went to grab my OnePlus 6t off the Dash ac charger and yep, you guessed it!!! Crashdump mode!!!! ?????
I swear man! And I wasn't messing with my device when it occurred either. I was not able to get out of it by manually holding power+ volume -&+ until I saw fastboot mode and then selecting start using power button like the three other times I've experienced this. So I went ahead and booted twrp, and did a clean install of OOS and formatted data and that worked. Is this **** contagious?! ? Tripped me out! Haha!!
I'd give the data format command: fastboot -w then run msm tool like the other user said to do. See if that works.
that sounds creepy.. you getting is 'crashdump':laugh:
i guess what is different in my case is i did not unlock oem. And so none of the commands are working. Phone was working fine and one morning fingerprint scanner did not reco. my finger so i thought of rebooting instead of other method to open and i get this error. i know there was no physical mishandling on my part so its difficult to believe that its a hardware failure and needs main board replacement as service center suggests. i have tried only msm tools (stated here in previous msgs) after service center gave a huge bill (230+)for repair.
and other commands as you stated but none of them have worked anyways so not sure if i did something wrong while self repair.
guess will do one more round format plus msm...

Far as I know fastboot and adb commands should still work but not commands like booting custom recovery...etc .. Also developer options and usb debugging needs to be set to "on" as well in settings. It sure seems like they would have made some alternate way to access these settings but if they did I've never heard of it. Tell you the truth I've never even used fastboot and adb on anything other than a device that is bootloader unlocked except to unlock the bootloader usually a a day or two after I get my device.. I really have no clue what works and doesn't with BL locked.
What mind boggles me is all over our OP6/6t forums you see people talking about this crashdump issue. And although I've been there 5 or 6 times on my 6t I've always been able to get out of it by holding down power + volume +&- until I see the fastboot screen then releasing. And I guess many people cannot do that. I wonder why? Maybe there are two different crashdumps...? Sure seems that way to me. I've always been able to hold my buttons down and get out of it by rebooting from fastboot mode. Many report they cannot do that. ?
(I wasn't even gonna mention crashdump. My luck my phone will go to it and I won't be able to get out of it like I've been able to before.) ?
Edit added:
sudo fastboot oem device-info
Use that command to show whether device is bootloader unlocked or not. See what it says if you type that in?
Maybe see what this shows afterwards as well:
sudo fastboot gatvar all
I believe your developer options and usb debugging was probably not flipped on as well, in settings?
bro fixed aleady? i got fix for you.
i have tried the commnads you have stated earlier.. still giving output here.
fastboot oem device-info
output below

OKAY [ 0.027s]
finished. total time: 0.028s
so it's locked
fastboot gatvar all gives the list of options that you can use with fastboot
most of the commands dont work and gives below error

yes developer options and usb debugging was probably not flipped either

FAILED (remote: Flashing Unlock is not allowed) Error

Hello, I just purchased a new "unlocked" 8 pro and attempted to unlock the bootloader. While in fastboot mode when I run the command
Code:
fastboot oem unlock
in my terminal I get "FAILED (remote: Flashing Unlock is not allowed). Does anyone know what this means? Is there a way around it or is the phone does this mean the phone is actually locked? Thanks.
You need to activate oem-unlock in developer settings first.

That did it! Thanks!
i cannot activate oem unlocking in develper options. I have a Oneplus Nord n10 5g the Tmoblie Version be2028.
Any suggestions I have been stuck here awhile?

Why not ask in your own device thread? If there are any special steps needed the folks there will know more.
