(Samsung) Possibility to check bootloader status using PC Is it possible to check bootloader status using adb of a samsung device back from 2014 or older?
(s5 and below) there's no fastboot, and no "OEM Unlock" in developer options
and since i need to get the info using pc

Do I need to program an android application to go with my desktop one to detect bootloader status?
If so, is it even possible to get bootloader status using an app?

Context:
I'm creating a desktop program which needs to determine bootloader status to do certain tasks. I have searched for ways to do it, i found 3 only, none work in my case

Using dialer to find it, I get no output at all..

Using fastboot, There's no fastboot, only download mode

Using an adb command, it helped but it did not output the bootloader status
On Samsung devices, if there is no OEM unlock in the Developer Settings, then the bootloader is unlocked by default. OEM lock is enabled on carriers models only. 

Moreover Samsung devices don't have fastboot, they have a proprietary protocol instead.
