    Thanks .

    if you can send the reply to me on my email it be really great.

    • Hi Rex,
      First, you can flash the Engboot file in AP section.
      Seconds, you don’t need to boot into recovery, just connect your phone to the computer, enable OEM Unlocking and USB Debugging in Developer Options

      • Hi admin, i tried it but after flashing engboot file in AP Section phone restarts and stuck at Samsung S7 Logo only. doesn’t go all the way. so i cannot Enable OEM Unlocking and USB Debugging in developer options, or do i need to wait a bit longer? because i tried yesterday waited for about 15 minutes. but nothing happens.

        Thanks for the reply by way.

        i hope we/you can help me fix this.

        Thanks.

      • I got an error admin

        “error: no devices/emulators found” when running cmd-here.exe

        after flashing the engboot file phone restarts and stucks at Boot Logo.
