Broken USB Debugging while unlocking bootloader - LG G7 ThinQ Questions & Answers

I've been following the steps to unlock my bootloader, and after inputting the "fastboot flash unlock unlock.bin", the command prompt froze for a good 5 minutes. After googling a video of someone doing the same thing, I saw they got an output almost instantly, so I cancelled the operation (through ctrl c), and restarted the phone.
Since then, the phone's pop up for authorizing USB debugging never came up, I've switched the protocols, tried different PCs and even factory reset the phone, but the problem is still happening.
Does anyone know how this could be fixed, if it can at all?
Thanks in advance.

Problem Unlocking

I've got my N7 bricked to where I can only get to fastboot. I made the mistake of locking it (couldn't get any fastboot commands to work, then that one decided to work). Now when I try to unlock it I use "fastboot oem unlock" at the command prompt it stays at "erasing userdata". It was stuck there for a few hours last nigh before I gave up. I've seen this issue online a few places, but no one seems to have an answer for it. I've tried different than USB cables and ports... No change. Here is a picture of the prompt: http://imgur.com/MevZn2n

Mine is also doing the same thing and it is stuck in a loop.
Same here!!
Virgin N7 2013... No hacking... Bootloader locked... started acting weird and I attempted a system restore. It now gets stuck at the Google screen. Fastboot gets stuck at erasing userdata. I have tried multiple USB cables on Win7, OSX, and Ubuntu. Help!!!

How to remove BootLoader unlocked notification from boot screen

Hey all. I'm in a bit of a pickle. My Tmobile LG g4 has stopped fast charging. When I plug in any cable, I do NOT get the USB notification which allows me to connect to my PC. Enabling the MTP option in the Dev options still does not allow the device to be connected to the PC to flash back to stock for warranty support.
Is there any way for me to save something to the SD card to reset back to stock? Do I have to connect it back to stock or at least relock the boot loader?
I've tried multiple PC's and multiple cables with no success to get the device connected. When connecting to a PC, I get. The device has malfuntioned on my machine.

does it go into download mode.? phone off vol up key and connect usb.?
if you want to remove unlocked bootloader follow this comands
UPDATE:
I was able to Lock the bootloader.
1. I connected the phone to my PC
2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in
Quote:
adb devicecs
- you should see the phone listed as one of the devices in the command line window
Quote:
adb reboot bootloader
- phone should reboot and you shouold see 3 lines of text on top
Quote:
fastboot oem lock
- nothing will happen on the phone, but on in the commandline it should say that it is done
Quote:
fastboot reboot
Phone reboots and the boot screen does not show the unlocked bootloader message anymore
Unfortunately, the computer will NOT detect the phone. No computer will. Using a USB cable that came with it , no luck either. Any ideas?

so basically theres no comunication with phone. not really. unless you go and exhcnage it to tmobile, so you cant remove bootloader unlocked message either. if you lucky and tmobile doesnt check for it then you may be able to get it exchanged. as it not recognized in any computer ill say its hardware problem. good luck.

HTC M8 excrypted and can not factory reset

o i woke up this morning and my phone tells me that it has been encrypted? First of all, How and why? I tried to do the factory reset which it was asking me but as soon as i did it, it just restarted and took me back to that screen without doing the reset. Tried to connect it to my pc with Bootloader but it did not find any connected devices and i can not even enable usb debugging mode, because i can not get pass the screen even if i enter the lock screen pin correctly.
I tried to find my device with "adb devices" command but it did not list it.
What else can i do? Please help.

Unlock bug

My phone started to lag. I restarted it and when I did this I had to enter the pin to unlock it, I entered it wrong, it seems several times and it makes me wait 30 seconds. I enter the correct pin and it does not recognize it, I keep getting the message to wait 30 seconds. How can I solve that? i guess its a software bug as i try i can't locate it using "find my phone". Should I wait longer to enter the pin? I already tried in safe mode and the same thing happens. I would not like to perform the hard reset. From already thank you very much
If you have USB debugging enabled you can use that by issuing commands via a shell, something like this https://www.google.co.uk/amp/s/www....-security-pattern-lock-adb-110928/amp/?espv=1
Or if you have a custom recovery then it's possible.
Otherwise a hard reset might be your only option.
Some information about your phone would be useful here - ROM installed, recovery, etc.
Peace.

Question Pixel 6 Pro stuck in fastboot, not from downgrading.

Hi All,
Apologies if this has already been covered somewhere but I've been scouring the internet for most of the day and come up with nothing.
tldr: My Pixel 6 Pro has been running absolutely fine for 9 months, no issues what so ever through all the automatic updates, I powered it off this morning to apply a new screen protector went to turn it back on and its been stuck in fast boot since with every option that can be selected returning to the same screen. Not been fiddled with, no root nor boot loader unlock.
Simply turned it off put the screen protector on turned back on and it has been stuck in fast boot ever since with a list of things below I have tried;
Restarted, no change straight back to fastboot.
Recovery Mode, no luck same as 1.
Rescue mode and using googles update/repair tool, cannot connect result is the same as number 1.
Restart bootloader, no luck same as 1.
Flashed barcode setting on and off (i know), device state & NOS Production some times change see non error image.
Flashing via android flash tool, boot loader locked wont allow. 'error getting device locked state -1'
Using force options confirms bootloader needs unlocking.
Connected to fastboot.exe on pc.
fastboot devices, correctly recognises the device is connected.
fastboot set_active a, FAILED (remote: 'error getting device locked state -1') message.
fastboot set_active a --force, same as above.
fastboot set_active other, same as above
fastboot reboot --slot a, accepts command with slower restart than normal but reverts to b.
fastboot getvar all, works list in attachments if its is of any interest.
Details of the device,
Contract device from O2 so probably vendor locked.
Was working fine but the past week or so there have been occasions where it wouldn't accept a correct pin, then would after about 5-6 attempts then be fine some time. I didn't pay it too much thought at the time as nothing seemed off and fingerprint was always fine but seems more relevant now.
I'm not enrolled for the beta.
I haven't tried to root or unlock the bootloader.
For the first time I've been pretty boring with a phone and haven't fiddled with a thing.
I don't think I've even had the dev options menu opened on it.
I refuse to believe its bricked itself for no apparent reason but google seems to be failing me or I must be looking for the wrong thing. There must be something I can do via fastboot surely given that it has got some form of communication?
If anyone has any further suggestions it would be much appreciated before I go down the return/replace route.
I assume you didn't have OEM Unlocking enabled before this happened. Without an unlocked bootloader, there is nothing you can do to fix it, because the bootloader will reject any of the necessary commands to reflash the device. If you're still under warranty, seek warranty repair; this is going to require replacing the mainboard, because no one has the necessary tools to perform a low level reflash.
If the bootloader was unlocked, fixing this would be fairly simple because you'd just have to reflash the boot image. But, as I described above, a locked bootloader rejects all the commands that would help in this situation, and there is no way to unlock the bootloader if OEM Unlocking was not enabled.

Kind of sounds like a stuck hardware button, either power and volume that's makes the phone think you are holding down buttons during boot to get into bootloader
Can you press the power button to start the system? If not, try this (it may be useful, but it may get worse, please be cautious) Hold on power button and volume down at the same time for 45s, When you press 30 seconds, the screen should turn off and restart to this interface. Then do it again as above, when it restarts to the interface again, try to press the power button to enter the system.translate form Chinese(simplified)_Google
