        He’s actually stuck in twrp recovery because he followed the instructions to flash the recovery image to the boot partition which is what happened to me. I was able to find a boot.img and flashed it to the boot partition and my phone starts to boot up but never completes

    • Jack

      Hold down the power button and the volume up buttons until you are out of the recovery

  • Kazan22

    Why do you have “fastboot flash boot recovery.img”? It should be “fastboot flash recovery recovery.img”

    • Extremely sorry for the error, Actually the file name recovery.img made me confused. The tutorial is now updated and thanks for pointing out.. 🙂 I am really sorry guyzz… and Disappointed..

  • outburstt

      • Kazan22

  • Kazan22

    If anyone needs to fix their issue: Download any M8 Sense rom, extract the boot.img and use the following commands in fastboot “fastboot flash boot boot.img”

    • Gary

      Could you point me to one? Do I need to have S-OFF for it to work? I’m thinking not since I was able to destroy it just fine…

    • Gary

      Does it matter if it was from a different provider’s phone? Mine is an AT&T

  • Gary

    Has anyone been able to recovery their phone after following this tutorial and writing the recovery image over the boot partition?
