Stucked with fastboot - OnePlus 7T Pro (Regular & McLaren) Q & A

Hi all,
Just bought yesterday this phone and after doing typical actions like android config (oem, debugging, etc.), installed adb and fastboot. PC recognized command adb devices and shows the phone but when I reboot to fastboot mode, it stucks and the device manager shows unknown android.
Have read all the tips here, forums, youtube, etc. but no way. Tried in 2 different computer with same results. Installed last android studio with sdk manager, same error. Installed oneplus drivers and also the same.
Even I have tried a different cable but no success at all.
This is so frustrating situation, ever more considering that I'm not newbie at this (years ago always changed rom every month and smartphone every 2 months).
Any advice? Format pc? Install other windows in other partition?
Or selling the phone and buying another brand

Did you select always allow from this computer after enabling debugging and plugging your phone into computer when phone was booted and running(not in recovery or fastboot. Also adb does not work in the bootloader only fastboot commands. Secondly search for the insecure modded stock recovery if you want to do adb access commands in recovery. There is also a fastboot d mode on our phones which look like recovery but you can flash all partions via full fastboot to get to fastboot d your phone has to be on then you type adb reboot fastboot

[Q] LG optimus c stuck in fastboot mode PLEASE HELP

i tried to flash a recovery and it didnt work and the phone is stuck in fastboot mode
use this
BUT, before you even do a thing, know that you have to use the files that are meant for your phone (you need the recovery and usb drivers meant for your phone; i believe you can use the other files)

My phone can't get to emergency mode and stuck in fastboot mode i have rooted my phone and backed up rom rebooted phone and went straight to fastboot mode what do i do
lg optimus c
Yes the tut didn't work for my phone. for some reason its not being recognized by the fastboot shell nor adb shell. I'd assume its completely bricked ? thanks for all the help.
My phone was not recognized by neither fastboot nor adb while in fastboot mode. "adb devices" and "fastboot devices" generated no result. Nevertheless, the following command worked flawlessly
fastboot flash recovery recovery.img
So, it seems that it's not necessary for the phone to show up in adb or fastboot.

[Q] Can't fastboot boot.img

Okay, so basically I am a HUGE idiot. My phone has been running the latest version of ParanoidAndroid and I decided that I wanted to try MIUI. I booted into TWRP v2.6.3 and wiped everything a couple of times before installing it, and I forgot to install the boot.img afterwards (it was s-on). So now everytime I turn the phone on, it is just always on the boot animation for an eternity, and my computer won't recognize my phone so I can't use fastboot or use an RUU. I am also unable to flash PH98IMG from the phone itself. Is there anything I can do to fix this? Thank you very much in advance.

Take out the battery, put it back together, power on the phone while holding down the volume down key til you get the splash screen, that'll boot you to the bootloader...
No I understand that, but there's nothing I can do from the bootloader. Once I get there, I can either go to TWRP or choose Fastboot. When I choose fastboot, it will say Fastboot USB after connecting to my PC but it will still not show up or be recognized (and I have the drivers). My only other options are Recovery (TWRP), factory reset (also TWRP), clear storage, simlock, and image crc. All I need to do is load the boot.img file, but it appears to me I have no way of doing that now.

Being seen in fastboot has nothing to do with the ROM at all, you need to troubleshoot this from the PC end. When you start fastboot on the phone and connect to your PC you get nothing? Not even a connect sound?

I do get the connect and disconnect sounds. Whenever it makes the connect sound, it doesn't show up under "Devices with Removable Storage." When I heard the connect sound the first time I went to the cmd prompt and typed "fastboot devices" but it showed nothing.

It won't show up as a drive at all in Fastboot mode, to see if it is connected properly go to Device Manager and look for ADB Interface -> My HTC, if it isn't there then your drivers are not installed properly. Drivers come from HTC Sync, which can be downloaded here: http://www.htc.com/us/support/content.aspx?id=6196 once installed and the connections in Fastboot and ADB verified to be working, HTC Sync can be uninstalled (the drivers will stay).
When you run "fastboot devices" you get nothing? Or do you get something like "< waiting for device >" or literally nothing?
What version of Windows are you running, you need to be on Windows 7 or older? Running under Windows 8 is not recommended.

Ah, that may be my problem then, as I am on a Windows 8 computer. I will try all of this on a friends W7 computer in the next few hours and report back with the results. And when I did fastboot devices it literally said nothing and was ready for another command. Thanks for the help!

You can also use a live Linux CD like Ubuntu and boot that and install the Linux version of ADB, it works fine.

If you can do "fastboot devices" then that means you are either in bootloader or fastboot mode. If that is the case, then "adb devices" would not find your device because it's not in the correct mode to be able to do so. You can access your phone with adb when it's either booted or most recoveries, but fastboot/bootloader mode is only for fastboot commands. Without knowing what phone you have and what update it is / was on, I can't really provide any more direct help. But typically there is a way to reload the OS via fastboot on most devices such as HTCs, Motorolas, and Nexus devices, to name a few.

adb devces does not work in clockwork mod either.....what is the easiest way to get this custom rom sent to my internal sd card if the phone wont boot up and os is wiped off the phone? it is an htc one...
adb should work in CWM... You might have to manually load the driver. Even if every driver works when the phone is booted and all, Windows can still have issues finding the right one in recovery. Check in your device manager. If that doesn't work, then you'll have to see if your recovery supports USB OTG and see if you can load like that. If none of that works, you'll have to reload the OS via RUU and start over with root/recovery/etc.
Mount USB and copy it from your PC to the phone or do sideload.

Neither of those things are options for the OP. He can't boot, so he can't mount USB (mounting USB in recovery hasn't worked for most phones since JB where most phones don't support USB mount - only MTP) and he can't sideload because he hasn't been able to get ADB working.
His options now are:
Find out why the adb driver isn't loading so he can just adb commands to push the file or sideload
USB OTG
Return to stock via RUU

Pixel shows up in adb devices but not fastboot

I'm trying to root a pixel (sailfish). I'm able to find the device in adb, but when I go into bootloader, the device isn't there. I'm mostly trying things on my Mac, which I used to successfully root a Nexus 7, but I also had the same issue on a Raspberry Pi. What's more is that I have a Verizon Pixel, which is detected in bootloader (but I can't root it since it's Verizon), and the problematic Pixel in bootloader isn't even registering as a connected USB device when I use the command, "system_profiler SPUSBDataType". Anyone have any advice?

Try
Code:
adb reboot bootloader
fastboot devices

I’ve tried that. It doesn’t show anything.
I have spent months trying to figure out how to get TWRP flashed on my Pixel Phones (I have 2 of them). I have searched & read many links on this forum and can't find any firm details/directions on how to get TWRP on a pixel. From https://android.gadgethacks.com/how-to/install-twrp-custom-recovery-your-pixel-pixel-xl-0175163/ it appears I should of installed TWRP on the factory image first, but I went to Lineage a couple years ago on Android 9 & this was not an option back then.
Both phones have the two latest version of Lineage OS, Both Devices are UNLOCKED, Both have Developer Options Enabled, and on my Windows PC I have the latest version of SDK tools & drivers installed.
Plugging into the PC is done with a a tested/good USB cable plugged into a USB 2 Port. Here is what I am seeing with LinageOS running:
adb devices shows List of Devices Attached
FA77LO302202 device
After executing - adb reboot bootloader
adb devices -> shows an empty list, hence doing a -> fastboot devices shows no devices.
Going to Recovery Mode in Bootloader list of devices shows:
FA76F0303478 unauthorized
In Recovery Mode -> Advanced -> Enable ADB list of devices shows:
FA76F0303478 recovery
I can Apply Update in Recovery Mode via Sideload, but that does not help me get TWRP flashed.
With no devices showing in the main bootloader via adb I can't get the phone into autoboot mode. Per the link at android.gadgethacks.com in order to put the Factory Image back on the phone, https://developers.google.com/android/images, I need to get the phone into autoboot mode.
Anyone have any ideas????
Come-on guys & gals. I'm sure someone can help me at XDA get my devices to fastboot.

fastboot doesn´t work on windows pc out of the blue

What has happend with fastboot? I have a rooted phone with twrp 3.3.1.0.
I have used fastboot commands to flash boot.img and recovery.img for years.
Suddenly out of the blue i can´t connect with the phone in fastboot mode. I have tried everything, all kind of different windows drivers, emma, flashtool, drivers from sony, latest driver form google. but i cant get my phone to show up as a device in fastboot mode using fastboot commands. Are there something that has changed lately?
I can connect in flash mode and adb commands works normal.
Usb debugging are on, and I have tried to boot pc without driver signature check.
I have read topics for several days googling and I simply cant get it to work in fastboot.
Please help.
