Stuck in fastboot menu - G4 Q&A, Help & Troubleshooting

I tried to follow the instructions throu the lg's website in order to unlock the bootloader of my phone (i installed adb and all) but my phone seems to be stuck in the fastboot menu. I never rooted it, i never flashed anything, it was always working (never stuck in bootloop) and now i get this. When i type in cmd "adb reboot bootloader" it works, but when im going to type "fastboot oem device-id" which is the next step, it doesnt do anything and the cmd says <waiting for the device> so i think that my phone gets stuck/freezes. However, if i open its back and remove the battery and place it again its all working (normal boot) like nothing happened. But when i try to do my job throu the fastboost mode i see nothing but only this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
EDIT: solved, i uninstalled the drivers from the pc and i let windows update install them for me.

Boot to twrp and flash a rom from sd or fix with lgup or flash tool in dl mode as stated you have the lg logo so u should still have those modes as you only deleted OS.

[Q] Can't use fastboot command suddenly

Before today, I have no problems with my phone and any other stuff, I have flashing & using almost every ROMs in the development section..
But suddenly, when I get into the fastboot mode to flash another kernel, it always stuck like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Tried using fastboot devices and other commands, they seem to work properly. All the flash & erase commands failed. using fastboot reboot-loader but no help.
What the worse thing is, I used flashtool to flash the stock .587 ftf package, so I have to use the stock ROM without Root now, and can't even change the kernel:crying:
Tried re-install all the drivers, still same problem. Google it but the only possible solution seems to be ---- try it on another PC, maybe it's the problem of my laptop's USBs.
I will try it on other PCs later, anyone have solution of the problem for now?
Thanks in advance...

It says relock then unlock could solve my problem.
But after relock, I can't even use the fastboot command to unlock the bootloader... still the failed(command write failed) problem...
try using flashtool. it may be the fastboot paths in your laptop have changed, flashtool should overcome that.

Please asus zenfone 2 bricked not working

The fastboot mode does not only enter black screen, nor download mode, I already tried to reinstall the fastboot by that program there but only of that error and never install, it is not recognized in the asus flash tools because the fastboot does not work, it is a brick already, I'm almost considering lost because I've seen all xda and all youtube and nothing works, rarely does it call and appear the ASUS logo and stay in it forever

g960w stuck booting into recovery

Hi. I have a phone, not mine, given to me broken in this state, so not sure how it got into this state. I can only reboot it into recovery mode:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Some things.
1. Volume up doesn't work. Apparently it didn't work when the phone was working.
I wonder if it's stuck in some position that forces it to go into this mode??
2. Tried to wipe cache and wipe data/factory reset, doesn't help.
3. Tried the "Apply update from ADB", and when I pick that, it tells me to run 'adb sideload <filename>'. So I tried to get stock firmware (G960WVL9FUJ1_G960W)YV9FUJ1_FMC.zip) and tried to sideload that from PC. Always gets stuck verifying the package (and 0% on PC adb).
Wasn't sure if I was supposed to do it with the zip or the files within the zip. Tried both and no luck
4. Tried to do it with SD card, it failed immediately (forget the error, could try to reproduce and tell you error if you think it will help).
5. Tried to use Odin. Cannot get Odin to recognize the phone at all.
I think drivers are installed properly (would adb devices work if the drivers weren't installed right??).
Not sure what else to try next.
Any suggestions would be welcome.
Thanks!

Moto g7 power

Is anyone able to help with this, I’ve got my G7 power unlocked, adb is installed fast boot shows the device I run fast boot devices,

...but you did download the file already?
https://twrp.me/motorola/motorolamotog7.html
...and did point correctly to the image-file's location?
fastboot boot path/to/twrp.img
I changed the file name and now it says it worked okay, however now when I go the refinery mode it just says no command

Do you mean recovery mode? Cannot recall ever having such error (or my frist coffe hasn't kicked in) but seems recovery wasn't installed after all.
Well, if you just want LOS, do you know this guide as well?
https://wiki.lineageos.org/devices/river/install
Apologies , I mistyped. When I run fastboot boot loader then select recovery mode I can see the android robot and just no command under it. Can’t do anything need to reboot again to be able to select anything.

Then I'd assume recovery wasn't written to the phone: Did you install the zip after pushing it to the phone? Was there any error shown?

[GALAXY A520F - 2017] Unlock OEM does not appear.

Greetings!
I'm trying to unlock Bootloader to install TWRP and it's not working.
Initially I went into download mode and tried flash TWRP but it returns an unofficial software message.
Searching the internet I found that I should activate OEM Unlock, but it doesn't appear on my device.
After enabling developer mode, I've tried:
1. Return the date in the settings (01/04/2018)
2. Reset factory
3. Flash last device rom.
4. I waited more than 180 hours.
I entered other suggestions that I found but none worked.
I tried to run the command "Flashboot unlock oem", but the device does not work when I enter manual mode. When I connect to the computer and type the command "adb reboot fastboot" the device simply restarts and does not enter fastboot.
If anyone has any suggestions on how I can install TWRP or make the option to Unlock OEM appear I would be grateful.
