i have a samsung galaxy grand 2 which have a broken screen that isnt responsive at all, and im desperate to get some important files and images off of it, but the problem is usb debugging is off, its locked with a pin and doesnt support an OTG, i havent tried to use ADB commands yet cause i dont have any experience and the phone doesnt have a custom recovery either, but its flashed from jellybean to kitkat. i will be very appreciated if someone can give me a solution?? what kind of options i have here?
After assessing your situation closely !
You only have 1 option.
The fact that you have no OTG, means no access is possible to enable ADB.. You also can not access it in any other way.
A few years ago, ADB would automatically be enabled on every boot, the system would then boot up and configure ADB as per user settings... This allows many root access programs to work correctly ( the reason most repeatedly restart the device ) ...
You may have to write a script for running batch commands, You can do this easily on Windows
adb restart adb wait-for-device adb pull /storage/sdcard0
A simple script used to exploit the vulnerability...
You would save that text file as commands.bat ( .bat is a batch file ) and run it...
This probably won't work however...
Your only option I could find, cost money and time.
Replace the whole front panel yourself...
People have already Assembled the entire front LCD & Digitizer, so no hassles trying to pry the screen off...
unscrew the old back
Take the back half off
Plug in the new front half ( LCD & Digitizer panel )
Screw it back together
It's fairly cheap to do it yourself...
This answer is not a guide but just an example of possible solution's.. Please be careful and take all necessary precautions whenever taking apart electrical devices.
There are also quite a few apps that (allegedly) allow you accessing your data. I had not tried any of these, but see examples:
Considering you have a locked device, that also has no access to ADB.

It's upon you, of you want to follow this:
18)Use Knox Remover to remove all Knox files.
Enjoy your rooted Galaxy grand 2!!! Now you can flash other recoveries or flash other custom ROMs or custom kernels.
Some useful tips(Experimental/WIP):
You can use Triangle Away to reset the flash counter after flashing ROMs and make your device status from custom to official. This is a really useful app. Report here if it works. You needn't download from google play, you can scroll down and download from the attachments.
@shabbypenguin: For CWM recovery.
@Chainfire: For SuperSU and Triangle Away.
@AL_IRAQI: For Knox remover.
After Getting CWM Recovery, DO NOT FOLLOW THE OTHER STEPS, THEY'RE SPECIFICALLY FOR ROOT ACCESS
Open CWM and Backup Data from Internal Memory...
Open the backup on your PC, it may need to be extracted with another software like 7Zip.
Extract precious data from the internal storage ... DATA/MEDIA/EMULATED/ - or similar.
