I have successfully flashed the eng boot.img via Samsung tool pro but after switching it on adb is still not active. I saw a post that claims I should load the official firmware to remove oem lock I have successfully done that but OEM is still locked. Please any solution is highly appreciated.

P.S the phone is SM-J737P refine edition.

And also all bypass solution on YouTube are not working to me.


The only solution i can think of is a method i personally discovered a few years back that has been adopted by other people and nicknamed "Pre-Hacked" ...

First you need to download a Hex Editor..

The firmware must not be encrypted...

  • Open your System or Firmware file in the Hex Editor, This may take a while...

  • Search for # begin build properties

  • Once found, you have located the Build.prop start.

  • Scroll through the build.prop, ( After "begin build properties" )

  • Find ( ro.frp.pst=/ )

  • Change the line to have a # before it ( Comment the line out )

    ro.frp.pst=/ to # ro.frp.pst=/

Now you have removed FRP by breaking the crucial property that tells FRP the whereabouts of your FRP Partition.

  • Save the file as a new file with the applied changes to Build.prop
