May be this problem is solved but for future reference I will post this two options

1 - push the original build.prop via adb when on TWRP plug the device to your PC

Open a CMD or a terminal (depends on your OS) Write this commands

adb kill-server
adb root
adb remount
adb push original-build.prop /system/build.prop

Or 2 / you can grab the current build.prop edit the density and then push it back

Commands

adb pull /system/build.prop /path/to/build.prop

Edit the build prop and then push it back

adb kill-server

adb root

adb remount

adb push edited-build.prop /system/build.prop

Maybe this problem is solved but for future reference, I will post these two options:

• Push the original build.prop via ADB when on TWRP
  1. Plug the device into your PC
  2. Open a CMD or a terminal (depends on your OS)
  3. Write this commands

     adb kill-server
     adb root
     adb remount
     adb push original-build.prop /system/build.prop
     

Or

• Grab the current build.prop, edit the density, and then push it back
  1. Grab it by using adb pull /system/build.prop /path/to/build.prop
  2. Edit the build.prop
  3. Then push it back

     adb kill-server
     adb root
     adb remount
     adb push edited-build.prop /system/build.prop
