[GALAXY A520F - 2017] Unlock OEM does not appear. - Samsung Galaxy A3, A5, A7 (2017) Questions & Answe

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.

[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.

Stuck in fastboot menu

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_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
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.

Huawei P6-U06 Stuck on Android Logo and Reboots itself

Greetings friends, I've come to you asking for aid to get this P6 back to working, this is a P6 my cousin bought to an operator here in my country (Venezuela) several years ago, after years of use the phone stopped working for him and it's stuck on the android logo and then it reboots itself until the battery is drained i guess, i did a little research in this forum and found out people with a very similar problem, to which I understand I should try flashing a rom with the 3 method buttons, now, the thing is, I get to the recovery using the 3 method buttons but all i get is 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_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I tried putting a rom into SD card but i i keep getting the FAIL thing, so when i try using ADB to flash a TWRP Recovery i don't get the PC or ADB to recognize the device, when i type "adb devices" it gets stuck on "< waiting for any device >" and thats where i am right now and i dont know what else to do or how to flash twrp since i can't get adb to recognize the device, any suggestion or help? thanks in advance for your answers and help
What you need is a custom recovery installed which would allow you to wipe the phone clean and then install all from scratch.

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

[Hard Brick] My cell stuck in hard brick.

Hi, 2 hours ago, I just unlocked boot loader.
But, I didn't know how to upload custom rom in that state, I think I used wrong code.
My cell worked till I used the code below.
fastboot oem unlock
fastboot flash abl_a
But, after that, I just spontaneously used the code below to upload custom rom..... (Why did I... sighhh)
fastboot flash abl_b
After I used the code, My computer can't read my cell and I cant also enter the fastboot mode.
Whenever I press any buttons on my cell, the only thing that I can see is this picture.
