    I know how

    Just send me a private message and ill tell you how I did it on my phone and I went thru razor_blade which you will need to extract 2 copys of and I struggled with it for 5 days so if you still need help I have the answer. I did some of my friends droid 4,s as well who were also in the same boat ,it just stopped at step 2 after you follow the smart actions and just sat there ! well not anymore anyway if u need help ill do it . ill even be kind enough to give you a walk thru over the phone if your having problems
    good luck and check out and download dan rosenburgs droid 4 utility method it still has razor_blade in it as #3 to root but # 4 also instantly installs safestrap even befoe I had it rooted I just tried to see if the system worked then removed it till I was rooted .
    Good Luck

    So I couldn't do the OTA update from GB to ICS for some reason, it just kept failing. When the JB OTA came around, I kept getting notices for the ICS OTA again. I decided that one way or another I was going to get my (rooted) Droid 4 to JB. I ended up getting to JB with razr_blade and I eventually got root (I was using a Windows 7 64-bit machine for that). The only problem was that the phone would not recognize the internal memory or the SD card. I decided to do a factory reset to see if that would fix it, but it didn't, so I went to reflash JB with the razr_blade tool. I thought I could do it again since that's what I used before to get to JB, but this time I used a 64-bit Ubuntu machine. This was the result:

    Code:
    jj@JJ-Ubuntu:~/Downloads/JB root$ sudo ./LinuxMacUtility.sh

    After that last bit the phone shut off and wouldn't turn back on. It won't even show a green LED when I plug it in to charge. Is there any way to unbrick this?

    looks like you bricked your phone, using DROID_RAZR_Utility_Jellybean_XT912_WinMacLin.zip not DROID_4_Utility_Jellybean_XT894_WinMacLin.zip
    no fix that I know of,
    if you used DROID_4_Utility_Jellybean_XT894_WinMacLin.zip
    could be battery, get a Motorola Programing Adaptor by Team Black Hat

    Thank you. It looks like I picked the wrong utility (I think I misunderstood that the Droid RAZR utility was the same as the Droid 4 - dang, stupid mistake). I will definitely pick up one of those factory adapters. Looks like it will be useful.

    I took my brick in to the Verizon store and they have shipped me a replacement already. I kept the brick and the replacement should be arriving today. Should I wait to get this factory adapter and try to fix my brick before I send it back to Verizon? Is there a chance that they will see the discrepancies and charge me for something? I did a factory reset right before the botched flash, so it's not like I have SU installed on there or anything. Any advice?

    I don't think that any data can be pulled from phone, seems that the razr firmware really bricks the droid 4.

    Not much you can do, and just an FYI, Factory Reset doesn't remove root (Superuser or SU) as a Factory Reset doesn't touch /system files. Your attempt at installing the Droid Razr system probably wiped it out though as that does overwrite system files.

    You can attempt to fix it if you Factory cable arrives soon enough...I think once you receive the replacement phone you have a limited number of days to return the defective one before they charge you full price ($549) for the replacement.

    Don't know if this will help but I saw in the tutorial how to unbrick the phone even with zero battery so check it out this may help .. Good luck

    There is a great tutorial on how to upgrade the droid 4 to JellyBean and have a working Pageplus config. The Fastboot JellyBean files for the D4 are released so now it will be no problem to recover the phone if there are complications on the way.
    Don't know if this will help bu I saw it will unbrick the phone so maybe give it a shot . I read the whole tutorial and its long but it does have great info

    Credit Goes to snoop1979 on howardforums with his method on getting the Droid RAZR/MAXX to work with Pageplus on JellyBean. The same steps can apply to the droid 4. The only difference is the SBF file you use on the Droid 4. The one on his tutorial is ONLY for the Droid RAZR/MAXX. Using it on the "Droid 4 will just instantly brick the phone". Below is a link to his amazing tutorial.

    http://www.howardforums.com/showthre...NG-on-PagePlus not this link

    good luck

    The link below is the correct SBF file to use with RSD LITE for the DROID 4
