A320F won't boot: custom binary blocked by fap lock - Samsung Galaxy A3, A5, A7 (2017) Questions & Answe

I googled like crazy for this, but can't get the device to boot anymore. Any suggestions?
I think USB debugging is off and OEM unlock is set to OFF. But how to change it when my phone won't boot anymore?

Locked Screen and USB Debugging

Hi everyone ,
I've got one question if it's possible to turn on USB Debugging with locked screen?
I've just tried by this code : *#*#7378432#*#* To get into and switch off screen lock but this code didn't work.

Help! Bootloader not recognised. Forgot to toggle Enable OEM unlocking :(

I unlocked my bootloader without toggling Enable OEM unlock in the developer options. Now my devices shows unlocked in bootloader but fastboot doesn't recognises it After unlocking everything got erased and now the toggle button in developer options is disabled! What to do? Can't even install recovery without fastboot. :'( Now after Is there anyway get fastboot working again so that I can go to stock and do the process once again? I just want my fastboot to work as it used to Reply ASAP. Thank you in advance

It's disabled, but turned on right? That's normal behavior for the OEM Unlock menu setting on Nougat. Enable USB debugging then try using fastboot.

That's most like a driver\cable issue. You can't unlock the bootloader without toggling OEM unlocking. Actually it seems there is a posibility found by Bitdomo but for security reasons he didn't shared it.
You're safe if you're unable to change the OEM Unlocking status in Developer Options because that's how it behaves. That's totally fine.
Make sure your download the Factory Image from the Factory Images Website and execute the flash.bat file when you're in fastboot mode.
Let the processes complete and your device will return to 100% stock. Cheers!
I'm sure my cable works. Because it worked first time when I unlocked it(without toggling the oem unlock option) with same cable and laptop. And I'm also sure that there is no driver issue because my device manager shows my device when I connect it in fastboot mode. But "fastboot devices" gives me nothing. I'm tensed and using my phone on stock android without updating any ota updates. I don't know what to do and I'm totally freaking out.
After your phone is in fastboot mode and connected to the computer, try going into control panel - device and printers - right click on your nexus 5x - properties - hardware - properties - change settings - driver - update driver - select manually - select from existing drivers. Now try the drivers one by one and see which one works

how to check if bootlader is locked

Hi Folks
I just got the Media Pad M2 8.0 and I want to check if the bootloader is locked or not
because there is no dialer installed I can't use the code I found in other forums
is there another way to find out?

Yes, there should be. You need to enter fastboot mode on the phone - i.e you need to get into the bootloader screen. The bootloader screen (usually called fastboot mode) will tell you if the bootloader and FRP are locked or unlocked - If it is locked, you should see "PHONE Locked" and "FRP Lock" in green, otherwise it should say "PHONE Unlocked" and "FRP Unlock" in red if the phone has been properly unlocked.
You can enter fastboot mode by either using ADB ("adb reboot bootloader", first make sure to enable developer options first as detailed in the Rooting guide, and then enabled USB debugging), or by first shutting down the phone and then powering it up while holding down the VOLDN (Volume Down) key. Of the two methods, I'd recommend the ADB method because the hardware keys method is usually hit-or-miss for me - sometimes it takes me to the bootloader, sometimes it boots normally into the ROM.
If you're on Windows and need the ADB and fastboot binaries, you can install the "15-second ADB installer" found in this thread.
Thanks, that worked, took me a while to figure everything out...
and it appears that my device is unlocked...

Did you try sideloading the OOS ROM?
Yes just now. It is installed without any problem but still the same. It sticks at OP logo...
Now i am going to find and sideload a former OOS rom

help me.

hello.
Trying to run bootloader on htc 10.
First of all I enabled developer mode in settings app and turned on USB Debugging but I can't turn on oem unlock.
What should I do?
Bootloader is already unlocked.
If you want to lock, then log on to https://www.htcdev.com/bootloader/ select your phone and go to the following pages. Maybe there is information about re-locking there.
Probably it is the fastboot oem lock command
