If you tap 8 times on your build number in Settings>System Information (or something along those lines), developer settings will be unlocked, allowing you to unlock your OEM.

e: You probably already tried that, since somebody else mentioned it. Here's a quite well-thought-out guide specifically for your phone, that i found online for installing TWRP, which you need in order to install Lineage, as i wrote earlier.

Downloads: TWRP (that's an unofficial build i found on xda) & ODIN

Step 1 – Download TWRP Recovery package for Samsung Galaxy Grand Prime and extract this file anywhere in your computer.

NOTE: Make sure you select the appropriate file above for your Galaxy Grand Prime model.

Step 2 – Download ODIN which will help you to install CWM Recovery on Samsung Galaxy Grand Prime G530H.

Step 3 – Switch OFF your phone. Now go to Download Mode. How? Press and hold the Volume Down + Home buttons together, and then press the Power button till you see the construction Android robot and a triangle. Press Power again to confirm to enter into Download Mode.

Step 4 – Make sure you have your Samsung Galaxy Grand Prime USB drivers installed on your computer.

Step 5 – Open ODIN on your computer. Connect your phone to your computer while your phone is in the Download Mode.

Step 6 – If your phone is connected successfully, one of the ID:COM boxes will turn yellow with the COM port number. This step might take some time.

Step 7 – Now select the following file that you have to flash/install on your phone. This file will be found from the extracted file in Step 1.

Click on ‘PDA’ / ‘AP’ and select the CWM package file you downloaded in step 1 for your phone.

Step 8 – In ODIN, check the Auto Reboot and F. Reset Time options, if not already.

Step 9 – Now click on the Start button in ODIN. Installation process will start and would take a few minutes to complete.

Step 10 – After the installation is completed, your phone will reboot into Recovery Mode automatically and install the root package / files. Your ID:COM box will also turn green.

Step 11 – After you see the home screen, unplug your phone from the computer.

That’s it! Your Samsung Galaxy Grand Prime has now been flashed with TWRP Recovery. To enter Recovery Mode, shut down phone and then hold down the Home + Volume Up buttons and press the Power button for about 5 seconds to enter Recovery Mode.
