fastboot loop aftering flashing - OnePlus 8 Questions & Answers

I'm stuck in the fastboot loop. After I unlocked the bootloader I got factory reset and I forgot to enable USB debugging which I believe caused the issue. Recovery doesn't work and MSM tools do not work. Tried a lot of button combinations to get into EDL with no luck, I'm guessing it doesn't work because it's not hard bricked? I'm not seeing the qualcomm drivers in device manager.

Turns out the "genuine OEM" cable I bought from ebay was the problem, now I can get into EDL mode and use msmtool

[Q] Bricked. Erased/messed up bootloader. Win recognized as "HS-USB QDLoader 9008".
Hello.
Finally I hard bricked my Photon Q. I think I erased an unlocked bootloader. Right now phone cannot boot into fastboot mode. Power+Vol up, Power+Vol down held long do nothing. After connecting to Windows PC, phone is recognized as "HS-USB QDLoader 9008". I found drivers on the net. RSDlite recognizes device, but flashing fails with message that it cannot switch phone from download mode. I found QPST service software used to flash bootloader. Right now I think the problem is that I don't have proper bootloader images for Photon Q, and to be honest, I don't really know what options to use (the software seems quite complicated).
Has anyone encoutered (and solved) similar issues? Do you have any ideas, what to do? I tried some generic Qualcomm files, but couldn't flash them.
Anyone, please, help me, if you can.

[Q] Unlocking the bootloader problem

When the Mi Mix 2S is in fastboot and the Unlock program on the computer says to connect the phone to the computer, when I do the phone screen displays the text Press any key to shutdown.
I've tried different USB type-c cables, different USB ports, tried re-installing the Fastboot drivers and what's worse is fastboot mode stays when the Unlock software is not running. I can plug in the phone to the computer while phone's in fastboot mode and it stays in fastboot mode.
Is the Unlock software supposed to say how long to wait before trying to unlock the bootloader?
Here is the updated bootloader unlock announcement from Xiaomi MIUI forums http://en.miui.com/thread-246705-1-1.html

unlock bootloader huawei mate 9

i got the bootloader unlock key from huawei and saved it in case i will need it, i want to unlock it now so i downloaded the latest android platform tools. i tried unlocking it using fastboot but fastboot devices didnt return anything (i used adb reboot bootloader to enter the fastboot mode) when the phone was in the fastboot mode (it said phone locked frp unlocked) i tried fastboot oem unlock [key] but it didnt find any device so i typed fastboot devices but it didnt return anything. i searched for almost an hour in xda and the internet and couldn't find anything helpful so i created an account and posted the question here (it didnt allow me to post on the root forum)
Have you put your phone in fastboot mode first. (Turn off phone and while holding down the volume down button plug in the usb cable to your pc) or download the Multi Tool application from https://pro-teammt.ru/huawei-multi-tool-eng/ and use the unlock bootloader with own key. Note that unlocking the bootloader will factory wipe your phone so make a backup first.

i tried it but it has the same problem, it sends the phone into the fastboot mode and then it cant find it, i connected the phone with usb cable and enabled all necessary options from the developer options in the settings
When you connect your phone to your pc and go into device manager is your device recognised. If not then either it might be a driver issue (reinstall all Huawei drivers), a usb cable problem (try another cable) or a usb port problem (try another usb port)

Question oneplus 9 got blacked out during flashing fastboot stock rom what can i do now

please read title and help
restore it with msm tool
how to connect the phone screen is black
If the screen is black it may already be in EDL mode. Plug it into a computer and check device manager for something like "Qualcomm HS-USB QDLoader." If that's there, you just need to get the MSM Tool for your model and make sure you have the right drivers.
If you can't get it into EDL mode, you will have to file a warranty claim with OnePlus, no other choice. Mess around with the buttons and see if you can get it to reboot or try the EDL key combo (hold volume up and down and while holding plug in the USB cable that's plugged into the computer). You don't have a chance of repairing it yourself if you can't get into EDL, end of story.
pc recognizing this Qualcomm HS-USB QDLoader in device manager but in msm tool it is showing n/a.and also in device manager it is showing triangle error on device.i am using official driver provided by msm tool poster.
Need some help unbricking (solved)
I bricked my OP9 doing some stuff today. It will not turn on, access bootloader, or anything. When I plug it into my computer, it makes a connecting sound, waits 10 seconds, then disconnect sound, then repeats the process. I tried using MSM...

It's can help you
Well you're not the only one I guess. That happened to me as well. So perhaps, Alhamdulillah I can help you out
The screen still remains black that means your phone is in the EDL and you'll need to get it out of it and then get back to EDL again to use msm.
Anyway, hold the power + volume up + down all simultaneously for a while. It'll take you to the Fastboot mode. Don't worry, it definitely will take you to the Fastboot mode.
Then you can do the rest of the flashing as you wish

Help stuck fastboot but no drivers?

Hello I have a moto edge I had havoc on there and TWRP but I don't even really know what happened but I ended up bricking well not really bricked I can get in yo fastboot but the computer doesn't recognize the device I've switched cords computers tried every driver I can find I even went as far as to make my own edl cable to try to get it to edl more which one of the times playing with the edl cable i got it to say unknown device but haven't been able to since then if i boot to recovery it boot loops and same with just trying to boot I'm at a loss of what to try to do test points? To force edl? Please help
no need for EDL mode if you can still access fastboot. you can just install the drivers.
in fastboot mode format cache partition, that will fix TWRP boot-loop.
How to do that tho ?it doesn't recognize my device at all but it recognizes any other device I plug in
in device manager find the device with yellow triangle exclamation mark
Yeah no it's not there and when I can get it to make the noise it's from my home made edl Cable it says device descriptor error or something like that I'll look to see what it comes up as but I've installed drivers of uninstalled all the drivers I've got Qualcomm drivers I've got Motorola drivers I've got I've done all that or else I would have had it solved already I don't know what's going on with it and that's why I was asking about the edl test points because the computer won't read it whatsoever now it won't even get into fastboot but it won't get into edl neither I'm lost
try in linux lsusb (no virtual machine)
I had tried on Ubuntu with no luck it doesn't do anything at all now unless I edl Cable it and it says unknown USB device device descriptor request failed
does not sound like Ubuntu error message.
No that error is from windows I do not have access to my Ubuntu atm
