[HELP] My phone won't turn on at all after bootloader unlock attempt(completely dead) - OnePlus 6T Questions & Answers

Hi,
Tonight, I tried unlocking my bootloader with adb. I did the usual thing (OEM Unlock on, USB debugging enabled, adb devices, fastboot oem unlock). However when I tried fastboot oem unlock, it says < waiting for any device >. I tried installing the USB driver that came with the phone when you plug it to PC. I tried fastboot oem unlock again and same result. I googled it a little bit and I found that you need to enter fastboot mode. So I decided to power off the device and boot into fastboot mode. However, when I tried Vol Up + Power button combo, it won't enter fastboot mode at all. There's no 1+ splash logo or anything, it just won't turn on at all.
The device was connected to my laptop and I noticed a driver was being installed on my laptop as the device was being turned off. It was QCOM BULK or something. Now whenever I connect my phone to my laptop, it's detected as Qualcomm HS-USB QDLoader 9008(COM7). adb devices won't list my device now. I also tried other button combination (vol down + power button, vol up + power button, just power button, vol up + vol down + power, etc) and my phone won't boot at all.
I'm extremely sure it isn't hardware or liquid damage, because the phone was working 100% flawlessly before I powered off my phone with OEM unlock enabled condition.
Please help me, I literally just got this device 4 days ago. I don't want to brick a 4 days old $550 device. I saved up all my money to get this phone. There's no official OnePlus service center in my country, so I probably need to send it to other country to fix it which will be very expensive and I won't have phone to use for weeks.
Any help is appreciated. Thanks
EDIT: I tried charging the phone for 15 minutes, it still won't turn on
EDIT 2: MY DEVICE IS FIXED! I fixed it by holding vol up + power button for a few minutes. I really thought it was dead, that was the most intense 2 hours of 2019 lol. Thank you to whoever wrote this thread -> https://forum.xda-developers.com/oneplus-6t/help/soooo-tmo-variant-6t-bricked-simple-t3866487/page2

You should not be trying to unlock your bootloader via adb. The unlock process is done via fastboot.

And before you attempt any fastboot operation, type fastboot devices in your terminal screen and hit enter to see if your phone is detected.

I had this problem and power with vol + for about 3-5 sec will reboot

This, but my phone was like 15 seconds.

if the above options dont work, you can try the MSMDownloadTool. That should reflash everything on the phone and let it boot. There is a walkthrough for it somewhere on the forum. Not sure which section though.

Bricked Storm

Hello, I have a problem with my storm. Two days ago I received it and flashed the then latest cm13 and its corresponding recovery. Everything seemed to work just fine until yesterday when there appeared to be an ota update. After the download finished, the phone rebooted itself and is since then stuck with a black flickering screen. Every attempt to start the phone using recovery or bootloader seems to fail, as the phone keeps showing me the black flickering screen, no matter the combination of keys (vol+/vol-) I use to turn it on. If during the black screen I plug the phone to the computer adb can actually see the phone but says it's not authorized to perform any command. On the other hand fastboot won't even see the device.
Is there anything else I can try before sending it back to wileyfox?
Thank you in advance
I've made some progress, I found out that the device can be forced to Qualcomm HS-USB QDLoader 9008 mode by turning it off and then connecting it to usb while holding vol+ and vol-.
I've also found the stock firmware at https://cyngn.com/support.
Now it would be great if somebody could help me, and the others in my situation, to figure the wole QFIL unbricking out, because I'm overwhelmed, and can't seem to find the right info on google.
Thanks to anyone who'll care to help, or share some info
I had a similar issue so have created a thread with stock recovery instructions, which resolved the issue for me.

Thank you for your reply.
Unfortunately this does not seem to be applicable to my case because on my device fastboot mode doesn't seem to work.
I've spent an entire afternoon trying to get it to boot to fastboot mode using different vol keys combinations and timings, but none of them seemed to work. No matter the combination, it just kept booting to a black screen flickering.
I'm starting to think that it could be some problem unrelated to my actions because if, as I think it is, recovery mode and fastboot mode are two separated things, nothing I did would justify this kind of behaviour.

Sorry to hear you are still having trouble, it does sound like the same issue, was a CM13 update from the last couple of days, upon reboot I saw the wileyfox logo but when the Cyanogen logo would normally show during boot it displayed a black screen, which would flicker every few seconds. Holding vol- and power to reboot resulted in the same thing so I was unable use recovery.
When the display was black and connected via USB I was able to see the device using ADB but like you no commands were authorised.
Leaving the phone plugged in via USB and holding down vol+ and power until it rebooted I was able to enter fastboot, once the fastboot prompt was displayed on the screen I attempted using fastboot to boot from a custom recovery, unfortunately that just resulted in the same blank screen for me. I also tried booting the stock recovery with the same result, I admit I did not try many older CM recoveries, but I wanted to revert to CM12.1 anyway, as the accelerometer and gyroscope not working in CM13 at the moment is no good for me.
Only thing that worked was a stock restore, so I think something beyond the recovery got broken as you could not even boot a previously working recovery.
For the sake of sanity it may be work getting someone else try booting it into fastboot before resorting to Wileyfox support. Though your phone is really new so could claim a refund or replacement from the seller, that would probably be faster.
FYI if you do end up sending it to Wileyfox support they do flash it back to stock, I had a broken screen replaced, was repaired and back to me in just under 2 weeks.
What would be exactly the timing for it to boot to fastboot mode?
Because I just tried (again...) to plug it to the computer while powered off, then it powered on on its own.
After that I rebooted it by holding together power and vol+ and immediately after it rebooted (right after the vibration) I let the power button go and kept holding the vol+ until the black screen appeared again... no fastboot

Hi,
Just tried a few combinations to check timings for you.
Powered off, not plugged in, holding vol+ while plugging in phone end of usb connected to computer, keep holding vol+ -> boots straight to fastboot.
Powered on, already connected to computer via usb, holding vol+ and power, release power when vibrates to indicate reboot but keep holding vol+ -> boots straight to fastboot.
Are you seeing the black and white Wileyfox logo when first booting? When going to fastboot it should skip that. If you are not seeing the logo it might not show the fastboot screen either. You can try following the steps above and then issuing fastboot devices from a command/shell session to see if you are in fastboot mode.
I hope that is of some help.
Thank you but I can confirm that neither of these combinations work for me. When rebooted/powered the device shows the wileyfox's logo.
If I use your first method it just seems to freeze on the wileyfox's logo screen, and the computer won't even see it (it's not listed on the usb devices list) so fastboot's not an option.
If I use your second method, or any other I tried, it shows me the wileyfox's logo and then proceeds to the black screen, which can be seen just by adb (not fastboot) but I'm not authorized to perform any action like you described for your issue.
I'm out of ideas so I'm sending it back and getting it replaced. On the cyanogenmod irc they told me that to brick it like that it cannot be done just by accident but it should require a lot of deliberate effort, and that just installing cm13 + recovery doesn't justify this problem nor does an OTA update, so it's probably some other (hardware?) issue with a very bad timing.
I'm kind of sure it's not the vol+ button that's damaged, because if I leave the device powered off and then proceed to plug the USB while holding together vol+ and vol- it powers on, but the screen stays off meaning the Qualcomm HS-USB QDLoader 9008 mode has been triggered.
Anyway thank you for your help, I could rule out my inability to start the fastboot mode and blame it on the phone xD
Hope I'll be luckier with the next one...

No problem, I hope you have more luck with the replacement.
Here I am again, new device, still can't boot to fastboot mode (this time I didn't flash anything, just unlocked bootloader so it's not bricked).
"adb reboot-bootloader" works, advanced reboot menu works, yet the vol+ combination hangs on the vendor's logo.
I'm contacting cyanogen os people to try to understand what might be the issue...
Could you please confirm that your device boots into fastboot mode when using the vol+ way? thank you

Hello again,
So these 5 methods work for me, someone else may have other experiences:
Phone powered off, hold vol+ while connecting USB, other end of USB already plugged into PC, continue holding vol+ until booted to fastboot (almost instant).
Phone powered on, already connected to USB, other end of USB already plugged into PC, hold vol+ and power until reboot vibrate, continue holding vol+ until booted to fastboot (almost instant).
Phone powered on and in OS, already connected to USB, other end of USB already plugged into PC, debug enabled, from ADB console, adb reboot fastboot or adb reboot bootloader
Phone powered on and in OS, advanced reboot options turned on, hold power, select reboot, select bootloader, reboot
Phone powered on and in Recovery, select reboot to bootloader
Currently I am running stock everything.
Perhaps try different USB cables or ports, though I still get to fastboot without the USB cable plugged in.
My Storm was a pre-order so is one of the first releases, it is possible they have changed something since.
Edit: I have come across a thread on the Cyanogen forums which implies this may be related to encrypting your device: http://forum.cyanogenmod.org/topic/117661-bootloader-hangs/ - I see you have been there already
as reference mine is not encrypted at the moment

how to factory reset a pattern locked phone

Hi. yesterday i bought a redmi 3s... i have put a pattern which i forgot and also a fingerprint unlock... the fingerprint unlock was working, until i tried other fingers to see if it could be fooled... obviously after too many tries, the fingerprint unlock won't unlock the phone without the unlock pattern... is there a way to hard reset such a phone ore delete user settings... i tried volume up + power button to acess the recovery menu, but when i acess it i get a weird menu saying:
your device has loaded a different operating system
for more info visit g.co/placeholder
if no key is pressed:
your device will boot in 5 seconds
if i press volume up or down, i get this menu:
power off
restart
recovery
fastboot
back to previous page
recovery and back to previous page return to the same screen mentioned above....
please help! :crying:
also, when i connect my phone in any mode to my computer via usb cable (download mode, fastboot mode, normal mode) i hear the usb connect sound but no folders open. I'd like to get to pictures made in the last 24 hours (thats the only thing you can acess without the pattern unlock on the side swipe menu).
You can still use the usb when boot using fastboot, just move to another port of usb in your PC/Laptop etc, for unlocking pattern :

With this options is nothappening nathing just again is going to restart it every 2 seconds. Vol up + vol down + pwer button on more of 15 sec is going phone on power off.
I made relock on bootloader because I wanted to take it away waring: your phone is unlocked an can't be trusted ....
well...youve learn the lesson the hard way...you just cant get rid of that nag screen...
only thing left now ( i think) is to ... send it to huawei for ressussitation...
cuz at that point i dont think theres a method after loosing ADB access

Hi! Have you repaired your phone? If not, the way is easy. You need plug USB cable and hold Vol-. You will enter bootloader. You should again unlock bootloader with your unlock code. After that bootloop is gone.
It could be that phone won't enter bootloader. In that case you should power off phone. Possible needed to disassembly and eject battery cable. After that plug USB cable and hold Vol-.

I have same problem too, and I bought the phone from china, can not return back, any solution ?
Hi...what have you tried till now ?
try hold power off button for around 30 seconds...
then try VOL-DOWN+ Power while plugged to pc....
i had same problem today. Thought i have ruined my phone. But trying to rebooting the phone while using variuos options with power volume up and down accidentally succeeded. It was in my case holding power and volume button until stopped appearing reload every 2 sec, then i have released the power button while kept holding volume up button. And lucky i booted in to Huawei erecovery mode. From there I have booted my Huawei Nowa phone in to a normal boot. Hope it helps somebody.
Hello.. i have the same problem here. It keep restart after 2 seconds. When i push the vol up + power button, it goes to recovery mode. Ive done wipe/reset factory n wipe cache. And still i cant switch on my phone.
Huawei Nova Plus MLa L12 restart every 2 seconds..
When it restart too fast, im also can't enter twrp and fastboot..It restart too fast and vol +- can't detect..If anyone have solutions for this problem, please inbox me..Thanks.
Hello i have the same problem, I tried all the combinations of the power button + volume button + and volume button -, but nothing works, I even disassemble the phone and disconnect the battery, then connect the phone to the pc with the cable, but nothing works, are there any other proposals?
same here... any sugest?

Cannot unbrick [cannot enter EDL mode]

Hoping someone can shed some light. Rushing to root phone again to send back warranty replacement, in my haste my laptop died mid flash and now can only boot in Fastboot and Crashdump Mode.
I am attempting to restore to factory via the MSM tool but cannot for the life of me enter EDL mode.
With phone powered off and pressing the vol up and down keys while plugging into the PC, it only enters Fastboot mode
I have tried to do it with phone off, rebooting from Crashdump mode, from fastboot and it seems that no combination allows me to do so.
I have also tried just vol up and vol down. App loaded at the flash screen, not loaded, etc.
Thanks in advance

What I did when I was in Crash Dump Mode was,
Press and Hold Power Off and Volume Up button and release when the screen goes off. Now your phone is switched off. Now to enter the EDL mode you need to press and hold volume up and volume down buttons at the same time...and then connect the mobile to pc while still holding the buttons. Done. MSM tool will detect your phone.
NOTE : Also keep the Device Manager window open on the PC while u connect the phone to pc and check if it shows up there.

It always seems to take me several tries to get it right. I think if I don't hit the vol +/- keys right at the exact time that's the problem. Just be patient and keep trying. The first time I did it, it took me what seemed forever. Thought maybe my phone was broken.

Hello Folks. So i have found myself in this situation as well. MY phone wont go off and keeps restarting to CrashDump Mode. As such can't seem to get into EDL mode inorder to flash. Any tips? I have tried all the above methods nothing seems to work. Is there a different key combination or a fastboot command i can use to achieve EDL? Help a brother i'm going nuts. Device IN2020

You just need to keep trying it. Make sure you hit vol+/- at the same time and hold for a few seconds, plug in the USB cable, then let off the vol keys. It's difficult to do and get right with two hands. Recently did it again as I wanted to upgrade to the 11 beta from a clean system. Seems like it took me forever to get it this time but eventually I did.
Use usb 2.0 port.
After using 2.0 instead of 3.0 and the phone connected stable for a while (after many tries)
able to finish the msm operation successful ..
But phone not booting .. getting black screen after 1+ logo
at this point I thought to clear cache but My phone is locked I cannot use any recovery .. I cannot even go into oneplu recovery LOL .. It seems like I am doomed
For me personally I could only get it to work on USB2.0 ports. On USB3.0 it just puts me back into fastboot mode or when it does go into EDL MSM tool just fails with a communication error immediately.
I kinda bricked mine as well messing around with GSI ROM's and flashing too hastily and to the wrong partition lol.
It has always worked for me with USB 2.0 port and non oneplus cable.
originable cable would not work for me on usb 3 or USB 2 port, but 3rd party cable start immediately with USB 2 port.
I've had the issue where EDL mode works..... for a few seconds, then the phone reboots.
Very frustrating!
The MSM Download Tool does spot the phone, but since the phone seems to reboot, I don't have enough time to do anything!
Any ideas why this is happening?

You need to already hit start on msmtool BEFORE plugging in phone
1- start MSM tool (prepare the settings and choose the right oos)
2-keep the cable connected to one end (I prefere to keep it connected from the phone side first)
3-keep holding volume up/down for 3-4 sec and connect the other end of the cable to your PC
4-your device will be connected directly stop holding volume up/down and in msm tool press start wait for ≈300 sec
5-now your device should work as it was before

This is a royal pita! I remember when it used to be fun....
Anyway, I've been trying every trick in the book, and then some, but shiznit just isn't going right! The holding of the up and down buttons would be easier if this was the pixel, but it is a tad hard to not mistakenly hit the power button on the other side.
The device manager shows the Qualcomm QDLoader and the msm Downloader is showing the infamous waiting for device... I've been at it for 8 straight hours and if there was a local OnePlus store that sold the international version of the OP8P, that's where I would be heading in a few hours.... It's really frustrating to say the least.
Anyway, when I'm in the bootloader, the device manager shows the Android phone, so I'm thinking that maybe I am in the edl mode when the Qualcomm port shows up, but like I said, the msm is waiting....
tried everything and it is constantly booting into bootloader. I even tried an adjusted fastboot script to boot into EDL but it still boots into bootloader. I have booted into EDL before on a OnePlus 7T, and I have tried multiple times by pressing the OnePlus 8 pro volume buttons at the same time, but always bootloader. Just to check, I tried doing it on my OP 7T again and it worked perfectly fine. Help????
I have had to flash stock 4 times because I land in crash dump mode and it has always been a tricky situation to get into edl.
What worked for me 100% of the time was following the steps in the youtube guide below.
From 2:30 onwards
Hope it helps
I had the same issues, but fixed once read comments as per above. Let me summarize what I did:
1. installed driver Qualcomm HS-USB QDLoader 9008 (I'm using Windows 10) - driver in a cab file should be unpacked using command expand (with proper switches) to preserve folders.
2. launched MSM DT and had it configured and then pressed Verify\Start, as EDL is available only for very short time - 2-3 secs with screen turned off.
3. as my phone was stuck in booting loop I was just keeping presses Vol+/- waiting for EDL to be entered, MDM will find the phone and start uploading data.
Just don't give up trying.

Try different ports. My usb 3 port would force it into fastboot but usb 2 was fine.
What to do if the device doesn't have any usb 2.0 port?

Can't unlock bootloader

Hi,
I have trouble unlocking my A40. It's 2nd piece I own and the problem is the same.
When I follow the steps from this forum;
Go to Developer Settings and enable "OEM Unlock" option
Power off the device and boot in download mode
In download mode, you will see the long press and volume up option to unlock the bootloader
Unlock the bootloader. That will wipe your device so be sure you made a backup of your data
After bootloader unlock, boot up the phone and make sure it is connected to the internet or it will trigger rmm prenormal
Setup the phone without google account and others
Reboot in download mode and flash the recovery and vbmeta images
Boot to TWRP
Format data in TWRP
Flash the Multidisabler zip
Now you can reboot
Click to expand...
Click to collapse
I'm stuck at the 3rd point.
I don't see ANY instruction about Volume UP + Power in download mode. Nor FASTBOOT see my device to run actions with it.
What I see is only "Volume down key + power key for more than 7 secs Cancel (restart phone).
And holding Vol UP + Power doesn't do anything.
How to make this work?
Thanks.

You did enable OEM Unlock, correct?
Turn the device completely off, without any cables connected. Keep a USB cable ready that's plugged into your PC.
With the device powered off, hold both Volume buttons, and plug in the USB cable connected to your PC. Do not press Power. You should see a prompt on either a green or blue screen; select the option for Device Unlock Mode.
Finally.
Thank you for making me try for another time
