MSM didn't work right and now stuck in fastboot loop - OnePlus 8T Questions & Answers

I can't get into MSM mode again, and there appears to be nothing else on the phone other than fastboot. I'd really appreciate any help.

Have you tried reinstalling the Qualcomm driver so that you can get back into MSM?

I did try this, but my problem was the fact that every time I tried to get into edl mode, it opened fastboot instead. The fastboot options were looping around really fast, like a volume key was stuck down.
I eventually got it into edl mode, making sure I held volume up+down for 10 seconds before plugging in to the pc with MSM already started.

Glad to hear you got back into EDL mode.
I've had the quickly changing state in fastboot happen also. I connected the phone to the PC and then used fastboot reboot bootloader to reboot the phone and that stopped the looping.

ah thanks, good to know - i've used adb commands before but I was trying to use adb commands but with the fastboot suffix "fastboot reboot edl" - - rather than "adb reboot edl". From the many variations of this, it seems there isn't a way to get from fastboot to edl directly, which is slightly annoying because it would've saved me.
Hopefully i won't get there again, but maybe the "fastboot reboot bootloader" will help if I do. Cheers!

Yes, there's no simple way to get into EDL from fastboot.
The other way that works for me from bootloader is:
- start MSM tool
- connect phone to PC
- hold Power+Vol Up+Vol Down until it connects to MSM
Easy!

[Q] Stuck in boot loop, can't detect in ADB or fastboot

Hey guys, I really need some help here, I'm not good at any of this stuff - my OPO just randomly got stuck on a boot loop, I have never played with the USB debugging or any of that or tried to flash anything else, I was using just stock cyanogen.
I've been reading around and I've downloaded all the drivers but still can't detect the device when I do the Shift + Right Click --> Run CMD "fastboot devices" or "adb devices".
I never enabled options such as the USB debugging or anything else, can someone please help me out? I'm really clueless to all of this stuff.
You must first put your phone in fastboot mode.
To put your phone in fastboot mode, turn it off, and then hold power+volume down until you get a screen with only the cyanogenmod logo. If you get to this screen, you're in fastboot mode. If you have installed the proper drivers in your computer, you should be able to connect to the phone from your computer. Connect your usb cable to the phone and the computer, open a dos box and type "fastboot devices". If you get a series of letters and numbers then you're OK.

This, except that's the wrong button combo (power + volume down is for recovery). Use power + volume up to get to fastboot mode and then try the "fastboot devices" command.

Thanks for your advice. This is the big problem I'm having, I've downloaded the SDK slim, and the driver manager and the 15 second installer things and installed all of them but still can't manage to detect my phone on fastboot.

Fastboot devices comes back with nothing in the CMD box, ADB devices gives a message that says 'Devices:' but there are none listed.

There's no point in using adb commands in fastboot because only fastboot commands work. What drivers do you have installed?

Uninstall whatever drivers you have installed, reboot your PC, install these drivers, reboot your PC, connect your phone, test fastboot (fastboot devices).

I tried that, but again no response in CMD when I type fastboot devices.
Although I just tried and am able to boot into recovery mode, would I be able to do some sort of factory reset there? I've already tried to wipe user data but I'm still getting a bootloop there.

I can't remember what capabilities the stock recovery has, but if it's there it's worth trying.

i am also facing the same problem that phone loops into fast boot mode whenever turned on i do totally every kind of drivers softwares and etc like tenorshare but all in vain i guess at last that phone must be enabled usb debuging in order to be detected as a active adb device,i pratically do this stuff by using another phone with enabled debuging and it was an active device andd can be processed further but when i disabled the usb debugging of same phone it was not working with adb interface i hope you understand,,,,but a miracle happenend i removed the battery for about a week and suddenly i pluged and try to turn it on hola it starts from roms boot logo

Get into fastboot while connected to a computer, then try booting your recovery image with the fastboot command. You'll need the fastboot binary for your platform. The command looks like:
Code:
fastboot boot twrp-[I]version[/I].img
ok ill give that a shot thanks

It's power and volume down.
If you can't even get into fastboot:
Your EMMC chip may just be fried, and all's lost.
But these symptoms could also come from a stuck power button.
If it keeps rebooting, it could be a power button issue.
I recommend removing the back cover, spray the power button with a bit of contact cleaner, quickly press and release the power button using a bit more pressure than normal, try and boot the phone.

OnePlus 6 won't power on, it only vibrates (nothing on screen)

Hi, I have a OnePlus 6 that was running Pie Beta 3. Yesterday it rebooted on it's own and kept going to qualcomm crash dump mode. At that time, I was able to get into FastBoot but not recovery. I then used the MSMDownload Tool which completed successfully but now it only vibrates with a black/blank screen when I try to turn it on. If I keep holding the power button down, it vibrates every 3 seconds or so. Now I can't get into recovery or fastboot. The only thing I can do is see my phone in device manager by holding down vol+ when connecting it to my laptop.
Any ideas would be appreciated.
Thanks!
Update, now it keeps taking me to fastboot mode every time I turn it on (even while only pressing the power button). I still can't get in Recovery mode.
If you're in fastboot, you already won.
Get TWRP on the start (preferably from eng.stk) > plug in to your PC > fastboot boot twrp.img
You can also find the Stock boot image and run it, see if that helps. fastboot boot <whicheverfile>.img

It is easy, you do not need to put it on the phone
You'll use this in cmd
fastboot boot (filename).img
Have you used fastboot before ?

Unfortunately, I have not used Fastboot before. I did install it with ADB but that's it.
I just connected the phone (device manager shows it's connected) and typed fastboot devices and it doesn't show any. I also tried fastboot boot filename.img and it just sits there "waiting for device" (even though DM shows it connected).
Any help would be appreciated. OnePlus remoted in and used the MSM tool which was successful but it still wouldn't boot so they told me to RMA it which will take about 10 days. I'm hoping to avoid that.

Cannot lock bootloader

So I'm trying to re-lock my bootloader,
I already looked up how to lock the bootloader and you can do that by booting in to fastboot and locking the bootloader from there. My OP6 was rooted but I removed all root related applications, I even reinstalled android.
I tought it would be as simple as unlocking the bootloader, but whatever I try I can't get my device to show up in the command promt when using the "adb devices" command while in fastboot. I tried reinstalling the ADB, fastboot and OP drivers a couple times but it doesn't help. I tried everything possible but I can't lock the bootloader.
Could somebody please help me with this?

You have to be in fastboot mode ( power off phone, hold power and volume up til you see fastboot on screen) on your phone to do want to want, if you cant do it that way,you can try this tool, https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892 , it will return your phone to stock factory fresh. It will be back on 5.1.5 software. Good luck

I can boot into fastboot mode (I said bootloader instead of fastboot, my bad), but the command promt does NOT show any devices, so I can't use this command. All drivers are correctly installed.

Yes I did
And I tried updating to android P but now I can't even access fastboot!
[UPDATE:]
I can finally boot into fastboot again, the only way to do this was to first boot into recovery and restart to fastboot from there.
And my device is still not detected by adb in fastboot
u do fastboot devices not adb devices
I just tried doing this in a Windows 7 virtual machine, but it gives the exact same results, I really don't know what is cousing this
Then take tool all in one
Well.... Use msm download tool then.. Since you can go to fastboot, it will reset everything and lock the BL.

You should do "fastboot devices" in fastboot mode!
I see thay you're doing "adb devices" instead which is wrong.

Flash to stock firmware from T-Mobile

I am trying to flash to stock/global firmware from T-Mobiles. I have already unlocked the bootloader but I am confused on what to do next. Some people say all you need to do is flash the system and boot images. But when i try to flash the system it says unknown partition. If I try to flash everything it says Critical partitions can not be flashed and I dont know how to unlock them, fastboot flashing unlock_critical is an unknown command. Please help!
Try on adb using " adb reboot fastboot" reboot to fastbootd and flash system, vendor.

Ive progressed a bit and decided to use MSM Download Tool. Although I cant seem to get into EDL mode. My phone is bricked so i cant use adb, and fastboot commands dont seem to be working. Ive tried button combinations but they just lead me either into recovery mode or fastboot mode.
In fastboot, type fastboot reboot fastboot see whether can boot into fastbootd or not.

This is a very simple fix. You can boot into fastboot, do that again, and flash LineageOS Recovery while your there
Boot into recovery, choose advanced options, than enable ADB. Boom, now you can use ADB on your bricked phone.
.
The command you're looking for once there is "adb reboot edl"
Also a lot of the guides on how to convert to Global either use broken methods, or link to the wrong files. If I had a dollar eveytime someone messaged me about following a guide and ending in crash dump mode I'd have a lot of dollars. DM me if you wanna know how to get to global and you're struggling.
