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?
before brick, it had being prompted for a while to upgrade the system software, I always tab later to postpone it. but yesterday accidentally hit the "upgrade now" then it was bricked after the phone was rebooted.
the screen stayed at the huawei logo and powered by Android at the bottom. I am able to push/hold the power button to power it off, but not able to power it up by any buttons or combination. it will automatically turn on (randomly) and stayed at the huawei logo for ever.
when the phone is on at the Huawei logo, connecting it to PC but either "adb devices -l" or "fastboot devices" shows nothing, no devices.
could anyone please share some light?
Thanks

Did you ever unlock bootloader? Could you enter fastboot mode? (hold volume - and power button). Or eRecovery (plug usb cable, hold volume + and power, until Huawei logo appear, release power button)?

unfortunately, I didn't unlock bootloader, so I can't enter fastboot mode actually. as I mention in the original post, I can only power it off when it's at the Huawei logo, but not able to power it on with any combination, it will randomly power itself on.
You have a corrupted /data partition, happened to me one day, on another huawei device (p9lite). You should, I said should, be able to reboot to huawei e-recovery, using power+volume up, release power after huawei logo shows up. Unfortunately you have to arm yourself with lot of patience and try to use an "unbrick guide" from another device. I'll try to find any info I can for you, but in the mean time you should look as well.
PS:/ I didn't even tried to install anything custom on this mate9, since it;s an expensive phone for me and I cannot afford to brick it up.
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.
Hi all,
The device I have is currently stuck on the Huawei boot screen, and it is unable to turn off as long as the battery has enough charge. Long pressing the power button just reboots the device back to the Huawei screen.
I was able to boot to the erecovery screen, or the HiSuite screen using both Vol+ & power or Vol- & power before. But since last night, I cannot do this anymore. No matter which combination I use, the phone simply reboots to the Huawei screen.
Connecting it to a pc also does not make it listed with either fastboot or adb, so I'm kind of worried that my device is bricked beyond repair.
Do any of you have ideas or advice regarding this situation?
Cheers,
Evert
Connect the cable from your phone to pc , hold the power button and volume down until it show fastboot 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

After rebooting my pc, and fiddling with drivers, I got it all sorted finally.
Thanks for your help, folks.

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?
