    Default USB Debugging Without Screen

    So I managed to crack my screen on my GN and it was rooted with Jellybean. It was insured so I was sent a replacement, but my problem is sending back the old one seeing as the bootloader is still unlocked. I used Wugs Root Toolkit to flash it back to stock and unroot it but in order to lock the bootloader I need to turn USB Debugging on but I have no control over the screen. Any suggestions?

    If your claim is for physical damage does it matter?
    If you can't use the screen they can't either so they'll likely just toss it out.

    Yeah that's what I'm thinking but I'd rather be safe than sorry if they decide to fix the screen and find an unlocked bootloader. Oh well I don't think there's anything I can do about it.

    You should be able to unroot and oem lock using adb.

    Even with USB debugging not checked on?

    Yeah. You should be able to flash stock images through fastboot using adb. No need for USB debugging. Wugs tool kit should even be able to do it. Use the "can't boot up" option under "Flash Stock and Unroot". It will boot the phone directly into fastboot, and flash it back to stock.

    I did flash it back to stock and unroot but after that it goes to the like activation screen upon bootup I'm assuming and USB Debugging isn't defaulted on. I tried using Wugs toolkit to lock the bootloader but it won't identify the device and I have to option that says "can't boot up".

    You should be able to boot into fastboot -- from off, while holding down volume up and down at the same time, hold the power button down until you feel/feel the phone vibrate.

    You'll be in fastboot at this point. You can either use the command line on the PC and do "fastboot oem lock", or maybe wugs toolkit would work (I use the command line myself).

    Alright I believe that did it. I can't see the screen but the command line did what it should so hopefully its locked. Thanks for the help guys, much appreciated.

    But is there a way to do adb push w/o USB debugging? The small thorn in my marauder's side.
