"SECURE CHECK FAIL : boot" - Samsung Galaxy S7 Questions and Answers

I just unlocked bootloader on my S7 and was installing magisk and did everything and got the AP patched magisk file etc, and got to Odin and started flashing only for it to fail with this error
Im not sure what to do as this is the correct verison firmware, I unlocked the bootloader, and flashed everything occardinginly

Did you follow the Magisk Installation Instructions?
After unlocking the bootloader, you have to let the device boot and confirm that OEM Unlocking is still available. Vaultkeeper/Knox Guard are still active even after unlocking the bootloader.

Hmm yeah that's what I thought but thought it was already so because...
I unlocked bootloader in dev options but when I boot into download mode it doesn't give me the prompt to fully open up the device it's just normal download mode :/
I tried booting into recovery and "restart to bootloader option" doesn't even exist, so I had to do it via pc
What should I do?

The OEM Unlocking toggle in Developer Options does not unlock the bootloader on its own. It's simply a "safety" that when enabled allows you to unlock the bootloader.
When you're in download mode, do you see "OEM LOCK" near the top of the screen? Does it say "On"?
To unlock the bootloader, unplug any cables and shut the device down.
Then, hold both VOLUME buttons, and while holding them, insert the USB cable from your PC. The device should start with a prompt - Volume Up for download mode, long press Volume Up for unlock mode, and Volume Down to cancel. Follow the prompts to unlock your device. This will wipe all user data.
Once you've unlocked the bootloader, follow the instructions in the link I posted to ensure Vaultkeeper/Knox Guard are fully disabled.

When I boot into download mode it just shows a normal download screen with no text in the top left, no nothing, it's just normal download. I don't get the option to unlock the bootloader as I've said in my last post

LOCKING BOOT LOADER
You need ADB so follow these steps.
To lock your boot loader you definitely need to have a proper connection between your device and computer.
To re lock your boot loader you need to:
1. Turn off your device
2. Hold your volume down button and press the power button. (KEEP HOLDING YOUR VOLUME DOWN BUTTON) You will see a white screen with fastboot written on it.
3. Navigate with your volume up or down to fastboot and press the power button to select it.
4. Connect your device with your computer,
5. Open the terminal in your computer and type in 'adb devices',
6. Type in 'fastboot oem lock' without quotes and your device is locked again, you will see relocked.
but i don't know the status of my bootloader.. if i have bootloader unlocked, i can re-use the zip to back to stock, that it includes relock bootloader
and if i have bootloader locked, i will unlock it
how i can know if it is unlocked or locked? thanks!

You could try flashing a custom recovery to it. If it works, then your bootloader is unlocked.

Only try to flash a custom recovery. If it works, you have unlocked bootloader.
Remember that locking back your bootloader can brick your tablet, and that locked bootloader is not needed for the updates.
I unlocked twice my unlocked bootloader and notting happened, it said "it's already unlocked" or something similar, but do at your own risk.
i dont flash a recovery yet but.. i can enter to android system recovery <3e>
does this mean that i have bootloader unlocked?
thanks!
EDIT. i flash twp2 and it works.. so i hadn't have my bootloader locked..
sure, i'm gonna flash ICS.. no more JB now

BLU Studio One Plus Unlocking Bootloader

Bought this device and everything works great and I have root. When I try to unlock the boot loader by going to "Developer Options" and checking the "Oem Unlock", I then
Code:
adb reboot-bootloader
At this point I do a
Code:
fastboot oem unlock
Which then the device asks me to use the volume buttons to confirm, Volume up for yes and volume down for no. The problem I'm running into is in fastboot mode it seems my volume up and power key are completely ignored. They work in recovery and in android but not in the boot loader itself.
I have tried unplugging the phone after sending the command over to see if that is a factor but it doesn't seem so. I'm only allowed to use volume down which denies unlocking the boot loader.
Another thing if anybody can get me a scatter file that would be much appreciated.

How did you root the phone?
Hoping for an answer to the bootloader question as well. For root I'm going to attempt kingoroot and replace with supersu

No download mode - LG Mobile Driver problem?

Hello, I have problem with my softbricked Nexus 5.
phone is full stock
bootloader is locked
USB debugging is not enabled
Android 6.0.1
all buttons are working
USB socket is fine
Factory reset from recovery mode is not working - still bootlooping
My purpose is to bring it to live, but I am stuck. Due to locked bootloader I have to use LG Flash Tool. Some time ago I used it with my other Nexus 5 and it was fine - worked excellent. Now I want to do it again with other phone but I am stuck on start: Can't enter download mode (volume up+usb cable). When I am trying to enter to download mode,charging battery icon appears and after few seconds my phone is being recognized as MTP USB device in device manager. I thought it is a problem with the phone, but tried with another working Nexus and there is no difference - it looks like problem with phone-pc connection to me. I tried few cables (original samsung and nokia) and two pc's - no difference. Tried all USB ports etc. Clean reinstall (with registry keys delete) doesn't help, updated version 4.2 neither. Do you have any ideas how to fix it?
Download mode? Never heard of that on the Nexus 5. There is a fastboot mode for flashing stock ROMs and to unlock the bootloader.
I recommend unlocking the bootloader and using NRT to flash a stock ROM.

I have NRT but problem is that to unlock bootloader I have to enable USB debugging - I can't do it with bootlooping phone.
Bootloader can be unlocked without enabling debugging as you are not running adb commands, you need to run fastboot commands.

Easiest way to unlock the bootloader on a windows machine is to do this:
make sure that the necessary fast boot drivers are installed;
boot phone into fast boot mode by holding down volume up, volume down, and power;
connect the phone to the computer;
type "fastboot oem unlock" without the quotation marks and press enter key.
Unlocking will wipe the phone.
Once unlocked, you can flash a stock ROM using fastboot commands.

Ok I did it. Do I have to proceed "fastboot reboot" command? when I am doing it it reboots and still bootlooping. When I enter bootloader it is locked again
If the bootloader relocks itself when the phone is rebooted, the memory chip is damaged and will need a motherboard replacement.

Pixel 3a - OEM Unlocking is active but no option to unlock bootloader

Hi Everyone,
I'm having some difficulties unlocking my Pixel 3a to install a ROM.
I have activated developer options, activated OEM Unlocking, but when I get into the bootloader, there is no option to unlock the bootloader itself...
The only options I have are :
Start
Power off
BarCode
Recovery Mode
Restart Bootloader
I have no idea what's happening and haven't found anything online that would even hint at what is wrong. Does anyone have any idea about what is going on with this ?
Thanks for your help.
when booted to bootloader you need to execute the command
'fastboot flashing unlock'

How to Unlock the Bootloader on Your Pixel 3a
The first thing you'll always have to do before getting your customization game on with most phones is to unlock the bootloader. Doing so opens the true potential of the device, allowing you to root, install TWRP, Magisk, custom ROMs, and other mods. No matter your wants or needs, there's no way...
android.gadgethacks.com
To Unlock bootloader
- Install adb and fastboot on your PC. https://dl.google.com/android/repository/platform-tools-latest-windows.zip
- Run through the initial setup if you haven't already, if you haven't don't bother logging into your google account.
- Enable dev options(settings>about phone>build number>tap it 7 times).
- Go into settings>system>advanced>dev options>oem unlocking, click the toggle.
- While still in dev options scroll down a little and enable usb debugging.
- Plug your phone into your pc. If or when the phone asks you to trust the computer make sure to check the "always allow this computer" check box.
Open up command prompt type into the cmd window
adb reboot bootloader
The phone will reboot into fastboot mode.
Now type into the cmd window
fastboot devices
See if it lists a device, if not you need to install the drivers I linked to. If you had to install the drivers try the fastboot devices command again after installing them, it should list the device now.
type in:
fastboot flashing unlock
You will then have to use the phone to select yes to the unlock. you use the volume keys to select and the power button to confirm.
Your bootloader is now unlocked and you follow one of the root methods.
reboot your phone

How To Guide The correct way of unlocking the bootloader

I AM NOT RESPONSIBLE FOR ANY DAMAGES DONE BY YOUR MISHAPS
Unlocking the bootloader on modern Samsung devices have some caveats. The newly introduced VaultKeeper service will make the bootloader reject any unofficial partitions in some cirumstances.
Allow bootloader unlocking in Developer options → OEM unlocking
Reboot to download mode: power off your device and press the download mode key combo for your device
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Go through the initial setup. Skip through all the steps since data will be wiped again in later steps. Connect the device to Internet during the setup.
Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader.
Voila! Your bootloader now accepts unofficial images in download mode.
