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?

  • Have you checked the broken screen wiki page? – Robert Feb 13 at 10:15
  • If USB Debugging is Off, you can't connect to ADB.. – Gadget Guru Feb 14 at 0:39
  • The only method, if you don't care about the phone is to try and install a custom recovery. Then you can backup the data... – Gadget Guru Feb 14 at 0:40

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.

LCD & Digitizer - Front panel replacement

Replace the whole front panel yourself...

People have already Assembled the entire front LCD & Digitizer, so no hassles trying to pry the screen off...

You just,

  • 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.

You could access phone data with ADB. This should provide enough information. This also may cover your question.

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.

Don't Bother With

• ADB

• FASTBOOT

8) Click on start. The flashing process will start.

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.

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.

  • Hello, Sorry for the delay but my phone is actually already rooted by a one click root app, it have been like that always but yeah i thought of getting a custom recovery but how will i do that? i have actually struggled on finding the no touch custom recovery for samsung galaxy grand 2. and again thanks for the reply :) – Thaer Taha Feb 20 at 23:13
  • You can find many recovery porting guide's online, I've personally only ever had luck porting MTK processors so I can't be much help in that direction... I'm currently running a custom port of TWRP 3.0.2 that I managed to port in about an hour... The trick is to ignore your devices name and look for CPU specific porting guide's.. It also results in a lot more guide's... – Gadget Guru Feb 20 at 23:20
  • Are you saying that i should look for CWM custom recovery that suits the CPU not the actual Grand 2? seriously all the links for CWM recovery for grand 2 are broken. – Thaer Taha Feb 20 at 23:38
  • Try TWRP and a Keyboard & Mouse to control it... Access the File Manager and copy your needed data to an SD Card.. Then take out the card and put it into a computer..duckduckgo.com/?q=samsung+galaxy+grand+2+twrp .... – Gadget Guru Feb 21 at 3:56
