[Q] How to make sure that bootloader is locked? - Galaxy Note 3 Q&A, Help & Troubleshooting

Hi,
How can I test that bootloader(Download mode) is locked on my Samsung Note 3(N9005) after I installed CyanogenMod?
Fastboot command tool doesn't see my device(I can see device with adb outside the Download Mode).
Is it possible to lock Download mode on Samsung device?
Thanks.

Only verizon version(sm-n900v?) is bootloader locked. N9005 is international so it isn't locked.

Hi, thanks for fast reply.
In this case it there an option to lock bootloader? Or replacing it with the one that I can lock?
Thank you.

Why you need to lock it?. Never see anybody asking how to lock bl. Samsung didn't make it lockable anyway.

It's recommended for security purposes. Google shows a lot of reasons to do that(can't post links due to new account, but search for "android bootloader lock security" will give plenty of examples)
So for Samsung it's impossible to lock or to replace it with something that could be locked?

Locking and all other things fastboot is made for is NOT MADE/WORKING for Samsung Devices except the Galaxy Nexus. You have a open bootloader and you can only flash by bootloader if you use ODIN.

An att note 3 900a running kk also has a locked bootloader.

Sure, but he has a N9005 ^^

I know, I was just commenting on the fact that the note 3 from att also has a locked bootloader. The remaining note 3 variants do not have a locked bootloader and they cannot be locked unless the locking is done by Samsung.

How to check Bootloader Status

I was wondering if anyone can tell me how to check if my Note 3 has a locked bootloader or not?
Can't seem to find anything on Google or on here on how to do it.

That is good to know, makes a change from being stuck with a locked one on my previous phones.
Thanks again for the reply!

Do you need to unlock bootloader or just root?

Hi guys. Bought a note 4 today, and it was rooted by a friend of mine using chainfire's method.
My question is, can you flash twrp or a rom without unlocking the bootloader, or is the bootloader not an issue and u don't have to mess with it?

hi ,
i have a N910F Note 4 ( Snapdragon ) i have used CF auto root by Chainfire , and flashed CWM recovery (as TWRP is not "configured" for N910F , only for Tmobile ,Sprint and i see now for Canadian models ) No need to touch Bootloader .I believe some Note 4 models( ? not sure which ) may have locked Bootloaders .
So make sure before you do anything,what your model no is etc .etc
Good luck

There is no way of doing it at the moment, not sure there ever will be.

Galaxy Y does not have a locked bootloader (that means you don't need to unlock it and forget about it)
It doesn't have a fastboot mode (means you can't use fastboot commands to flash it)
You will need CWM recovery to flash ROM or kernels,
Just check this thread http://forum.xda-developers.com/showthread.php?t=1974338

If it's still locked, do you mind keeping it that way for just a little bit? It's possible we can figure out how to re-lock if we can get a bootloader dump. It's also possible that unlocking your bootloader will report to ASUS that it's been unlocked and it will void the warranty even if we can figure out how to lock it back up.
Maybe try this tool: https://play.google.com/store/apps/details?id=ma.wanam.partitions
And then report to this thread: http://forum.xda-developers.com/zenfone-2-laser/general/ze600kl-official-bootloader-unlock-t3273263
