Hi,
i had to reboot my phone cuz of issues and out of no-where my phone got stuck on the boot menu.
when i'm talking about the boot menu, i talk about the menu where you can select 'start, restart bootloader, recovery mode, etc'.
when i connect an USB it doesn't get recognized, but i do hear the sound from windows after about 5 minutes that a usb has been connected. ADB doesn't see the device.
its entirely stuck and can't select a select a option using the volume buttons and power buttons, they appear to do nothing. also the phone says its charging and the USB is connected while it's not.
this seems to be a screen freeze, but i don't know how to fix it.

Hello. I was in the boot menu whilst using my Samsung Galaxy S8 (I was just looking around) and entered the bootloader.
I see a blue screen with a down arrow which says "Downloading... Do not turn off target"
The phone will not receive any input and I cannot turn it off.
I have tried to use fastboot reboot to reboot the device, but the device isn't being detected (In the device manager it says "Unknown USB Device (Device Descriptor Failed)").
I'm sure if the device dies it will boot properly, however I would not like to wait that long. Any help would be helpful, thanks.
just long press the power button (for 15 seconds or so). It will restart.
I have tried this already, a restart has not happened. To make sure, I tried it again and timed it for 25 seconds, the device did not power down.
Try holding both power and volume down.
That worked, thanks.
I've never had a device which required that combination. Perhaps I should have tried it first before posting, regardless, you have been a big help.
I changed my battery and now it only goes to the Reboot bootloader screen. The arrow keys don't work to change the menu. Sometimes I can get it to Recovery mode, but neither the power key or arrow keys will work. Once I got it to the Start, but the power key did nothing. I have it on the USB port, but ADB devices returns no devices, so even though I installed the Google USB drivers in Android Studio I can't get the computer and the Nexus to talk to each other. Any other ideas of what I can do?
I currently own an LG G6 AS993, and seeing as there is not going to be an OTA Pie update for the phone, I thought I'd go ahead and get a ROM instead. There's just one problem, and that is that I can't even get into the bootloader to unlock it.
Here's what I've tried:
1. Using ADB commands, adb reboot bootloader, adb reboot-bootloader, fastboot boot bootloader
The phone was recognized in adb devices, however, after entering these commands, the phone just booted normally back into android, like a normal restart.
2. Using the volume and power buttons. I held the volume up button and plugged in a cable that was connected to my PC, and it booted into 'Download Mode' and then proceeded to a "Firmware Update' screen. After pressing down the power button it brings me to another screen with the options to view some wifi details, 'Power Off', 'Phone Info', and 'Back', which brings you back to the "Firmware Update' screen.
I also tried the same but this time while holding down the volume down button, and it shows the phone booting for 2 seconds, and then turns off and proceeds to show the battery symbol with the amount of charge.
These are the only ways of getting into the bootloader I've seen for this phone, and they simply do not work, so if anybody could help that would be very much appreciated!

Hey Got same Phone LG G6 as993 and same problem... It wont get into unlock bootloader option after try several adb drivers... it only restarts. Dm me if any updates
Hello dear xda community
I have a px6 device from the company "Wondefoo" installed in my Mazda (without any hard buttons). It worked so far so good, but ZLink (Apple Carplay) didn't work, so I tried to fix this. To do that, I rooted the device, uninstalled the "ZLink" app and reinstalled a newer version. Then I tried to reboot. And then my problems started:
The device doesn't boot anymore. It tries to start up, I can see the Android 10 boot logo ("multi-media on-vehicle Navigation System" screen), but after about one minute, this logo disappears and the screen remains black.
OK, easy fix --> Just go into recovery mode and reset the device. But here's the big problem: I can't get into recovery mode.
Here's what I tried:
1. Ignition off and on --> Screen still black
2. Press "Reset" button (my device only has this one physical button) --> Boot process started again, but same outcome
3. Unmount the device, plug the power out, wait an hour, plug it in again and try again --> Boot process started again, but same outcome
4. Tried to connect with adb over Wi-Fi to the device (used the last known IP address) --> Connection timeout, Wi-Fi probably not started yet
5. Press&Hold "Reset" button until lights beign to flash to get into recovery mode --> Lights never flash because the "Reset" button somehow breaks the power circuit and when I release it, the device gets power again and boot process starts again with same outcome
6. Press&Hold "Reset" button for a minute, then release it, then press it again quickly within 1sec --> Boot process started again, same outcome
7. Tab with 5 fingers on the boot logo --> Nothing happened
8. Attached keyboard and pressed "Alt" + "PrintScreen" + "I" all the time --> Nothing happens. Keyboard is with RGB LEDs, so I saw it was active when the boot logo was displayed... Then, the LEDs on my keyboard turned off which was telling me that there is no keyboard input possible anymore
9. I even tried this: https://forum.xda-developers.com/t/new-method-enter-recovery-no-physical-buttons.4013453/ --> I just have one similar cable, not two as described in this post... So I put everything together again and just tried again --> Boot process started again, same outcome
Well... Is there any option left? I'm thinking about buying a USB male-to-male cable and try again with adb, but everyone tells me that I need to get into recovery mode first which I really can't
* Is there any other way to get into recovery mode? Maybe with my keyboard?
* Does anyone have another idea what I could try? Maybe without recovery mode?
Thanks in advance and cheers

As you said:
1. Ignition off and on
2.Have ready the needle for reset and do that instantly as you see the boot logo.
Once device restarted, wait until will see the boot logo again and pull out the ignition key.
3. Put in an USB socket a pen drive with the right firmware
4. Put back the ignition key and let it in ON position, without starting the engine. The update process will start, have a bit of patience until will finish. The device will restart at the end of the update, and straight after the boot logo, shortly press the reset button.
With a bit of luck, will have a fresh firmware on your device.
Thanks for your quick answer.
I tried what you said several times, but unfortunately I always end up on the black screen, no matter what I try.
My usb stick flashes quickly during the boot process, but nothing happens with it.
I also tried with an USB male-to-male cable and connect via adb, but it won‘t connect...

Are you sure you are holding the reset button for long enough?
On my machine (Dasaita) you hold the reset and the machine turns off... but you have to keep holding it even after it has turned off. Could be upwards of 1.5 minutes. Once the lights flash (and finished flashing), release and press one more time within 3 seconds.
Thank you for this idea. I have tried 30 seconds, but no more until today...
Now I tried with 1min, 2mins, even 3mins, but nothing happens.. I think the power is immediately cut as soon as I press the reset button. So there is probably no way to fix this easily
I also contacted the seller, but they have a talent to not understand my question. I just get answers like "press the reset button 2 sec and then everything is fixed" or "plug in the USB drive with the new ROM and press update" - of course that doesn't help.
Well I guess I'm left with one last thing: Throw this device away and buy a new one. Not from Wondefoo anymore of course, and hopefully with a working reset button.
I have the same issue. What did you end up doing?
Where did you buy your unit from?
I have been trying to flash 13 on my ADT-3, and I seem to have screwed up. Now all I get is a bootloop, and if I hold the device button on boot, I get the screen with the green Android/No Command.
Any suggestions to try to recover?
You'll need to have the usb cable connected to a computer in order for a button press to establish a usb burn mode connection. When the button press is done, if the device doesn't detect a usb connection, it will instead skip to booting to recovery.
then you need to hold the "only" button again ~ you will see the menu
