    I did some research and there is so much information to process, It seems that a have an "easy fix" here, but I cant seem to get it to work. I bought this phone and it has been dropped from about 4 ft down, as a result it has a cracked camera lens. The phone it self is in excellent condition, it turns on and after the MOTO logo it takes me to the black screen where it says:

    Bootloader

    2c.7c

    Battery OK
    OK to Program
    Connect USB
    Data Cable


    What do I do now to get this phone to work?

    When I press the X while holding the ON power button, it takes me to SPRecovery. I dont know what to do there I tired to select wipe data/Factory reset it successfully completed that, then I rebooted the system, but it took me back to the Bootloader screen.


    This are all the options in SPRecovery:
    reboot system now
    wipe data/factory reset
    Wipe cache partition
    mount options
    backup/restore
    install

    Please help, thanks

    You need to use rsd lite to flash an sbf. I don't have any links, atm. I would suggest searching for "Motocache1 root regardless". It will take you to a thread here in this forum that will explain how the process works.

    If you have any problems, let us know.

    I hope I didnt screw up my phone comepletly

    I downloaded the RSD Lite 4.9 and This SBF VZW_A855_ESD56_QSC6085BP_C_01.3E.01P_SW_UPDATE_03.sbf

    When I followed the steps in the above guide, it FAILED the processing. I couldn't turn off the phone so I took out the battery. When the phone turned on it said:

    Bootloader
    2c.7c

    Code Corrupt

    Battery OK
    OK to Program
    Connect USB
    Data Cable

    Please help.

    The model# for the D1 is A855, do you have a D3?

    That is FRG83D, which will require one more update to be up to snuff.

    If you flash that, and it still returns to the Bootloader, thats when the trouble starts.

    /facepalm I just looked at the phone model in the user profile and not the actual posts. Sorry about that, I thought I was on to something, carry on

    Thanks for sharing, however when I downloaded the zip file, I took the SBF file out of the folder so I can locate it through RSD Lite program.

    I plugged my phone via usb to my computer it took me straight to the bootloader screen without pressing the D pad.

    I turned off the phone with power button, then turn it back on while holding the right or up on the dpad

    The phone is recognized on RSD, then I browse the SBF that you provided for me, hit start

    It does its thing until 99% it says Phone [0000]: Error switching to BP Pass through mode (0x70BE); phone disconnected.

    Then STATUS reads Failed flashing process.

    Result: FAILED

    Phone screen still reads SW Update In Progress... and cant be turned off unless I take out the battery. The interesting thing is when I put the battery back in the phone goes right into the black screen with bootloader message with out the MOTO logo showing first.

    Am I doing something wrong here?

    Ok so after doing hours of reading and trying different methods moving around SBF files around C drive, desktop, documents, downloads as recommended by some users, NOTHING has worked I still can not get my phone to work?

    What I was able to do is remove the "code corrupt" message in bootloader screen by downloading and running this SBF SPRecovery_ESE81.sbf now the phone boots up with Moto logo, but then goes to bootloader screen saying:

    Bootloader

    2c.7c

    Battery OK
    OK to Program
    Connect USB
    Data Cable

    If I turn on my phone holding power button and X it takes me to SPRecovery. What can I do now to make this phone have Android OS on it and make it work?

    Please help.

    ^ will try to do that. I was thinking do I need to download Android OS on like an SD card to install it on my phone, or what is ROM that I have been reading about?

    Or the only thing I need to worry about is to upload a GOOD SBF file via RSD Lite? Thanks
