[Q] Bootloader status locked or unlocked? (Samsung)

[isabelamoisin]

How can I verify if the bootloader is Locked or Unlocked on Samsung Galaxy? S4 mini GT-I9195 (Android 4.4.2 KitKat)

- I have googled after this for few days now and I can't find nothing.
As I see, some old Samsung models (like s3) have the bootloader unlocked and some carriers variants lock the bootloader.

But how about S4 Mini? All that I can find is for other phones like Sony Xperias.

On http://autoroot.chainfire.eu/ I did find this but is not explaining how to unlock or how to check the status of the bootloader:

" UNLOCK BOOTLOADERS
If you have locked bootloaders, flashing one of these will probably brick your device - with the exception of Nexus devices, which will usually automatically "OEM unlock" and wipe your data !" "

On http://wiki.cyanogenmod.org/w/Install_CM_for_serranoltexx

I have found this:

" Samsung devices come with a unique boot mode called Download Mode which is very similar to Fastboot Mode on some devices with unlocked bootloaders."

Can you boot into download mode ?? Power off the phone. Then Press and hold Volume Down , Home and Power/Lock keys @ the same time till device vibrates.
You should get a screen saying "press volume up to continue" and "volume down to restart". Press Volume up and make a note of text on next screen. Come back and report.

ODIN MODE
Product name: GT-I9191
Current Binary: Samsung Official
System Status: Official
Knox Kernel Lock: 0x0
Knox Warranty Void: 0x0
CSB-Config-LSB: 0x30
Bootloader Ap Swaev: 2
Write Protection: Enable

What dose it mean the one from above?
- Current binnary System status official => stock rom/firmware?
- Knox Kernel Lock => ?
- Knox Warranty Void: => Is valid and not trigered
- Csb-Config-Lsb => ?
Bootloader Ap Swaev => ?
Write protection enable => BOOTLOADER LOCKED?

Isabela,

Our devices Samsung (in general all Samsung devices) don't have locked bootloader. So you/we must only root our devices for flash some custom kernels/ROMs.

Good luck

This is why I am asking. For downgrading the firmware and rooting. Without briking.

I have used TowelRoot with succes, for having root on the device, but after a factory reset and some updates, TowerRoot is NOT working anymore.

So, I wish to downgrade to an older firmware/stock rom without (soft) bricking the device.
KingoRoot is also not working, and is asking me if I wish to:

""Kingo will now start to root your device by flashing custom Recovery through Odin Mode, which will
1.Definitely void your WARRANTY (I don't care)
2. Possibily BRICK your phone and lead to boot failure
(I really care as I wish to avoid bricking)"

Also on chainfire auto root I have found this statement but is not explaining how to unlock or how to check the status of the bootloader:

" UNLOCK BOOTLOADERS

@isabelamoisin
You have latest knox bootloader. It is impossible to downgrade to jellybean 4.2.2
But you can root your device by kingo/towelroot even if u are on latest firmware.

Sorry to bring this up again. But if we are able to access Download mode, then is the bootloader unlocked?
EDIT: Btw, I have a Samsung Galaxy S3 Korean (SHV-E210K) (by Olleh) and I tried going into Download mode but its all in korean so I didn't understand anything.
