1. You want that $100.00 in your pocket or an Amazon Fire TV don't you? Well here's the deal. With our new updated look we are in desperate need of an updated logo. The 'old' one has certainly served us well, but it's time. Find all the details here: bit.ly/1q0k6Wa

    Sigh...

    Trying to resolve my tethering issue after leaked OTA upgrade to JB ( http://www.droidforums.net/forum/droid-4-general-discussion/239983-tethering-after-jb-update.html ), I deleted some system files. My bad... doing so did no harm in ICS. Should not have taken the chance in JB.

    After reboot I'm stuck at the swirling red droid logo. Tried to get into factory reset, but can't get past android exclamation mark (no response to volume up & down, eventually reboots).

    Here's what I did, per: http://www.droidforums.net/forum/droid-4-general-discussion/224932-help-using-droid-4-canada.html
    3) Open Root Explorer and go into /system/app folder, press the "mount r/w" button and rename the following files to .2 :
    - VzwPhoneService.apk
    - VzwPhoneService.odex
    - VzwController.apk
    - VzwController.odex
    - VzwDeviceSetup.apk
    - VzwDeviceSetup.odex
    - VzwEntitlementService.apk
    - VzwEntitlementService.odex
    - vzwapnpermission.apk
    4) Copy the build.prop using Root explorer to build.prop.2 and edit the build.prop in a text editor with the following changes:
    ro.telephony.gsm-routes-us-smsc = 0
    ro.cdma.home.operator.isnan = 0
    ro.mot.lte_on_cdma = 0
    ro.cdma.subscription = 0
    ro.mot.phonemode.vzw4gphone=0
    Save the file an exit, always keep build.prop.2 around just in case you ever need to roll back ​

    I have backups of the files I messed, obviously, but can't get back in to fix this mess.

    Any help?

    Just occurred to me that the phone's probably not charging anymore, but constantly going. Guess I've got a limited time before my battery's dead. Will I be dead in the water then?

    Unless you can access the stock recovery to reflash the ota update you're in a world of hurt. No fastboot files yet either. And no safestrap to create a romslot. Not a good position to be in.

    Sigh... I feared as much. Thanks for the response, hopeless as it may be... :(

    Made some progress, I suppose. After no fewer than a dozen attempts I finally got to the recovery screen, but applying the original OTA updated from SD failed at verifying the current system. Install aborted.

    I guess it's much too early for someone to have developed a way to rewind to ICS?

    AFAIK, as soon as you upgrade to JB, there is no going back to ICS to re-patch to JB, even via SBF. At least, not until someone releases the JB SBF files.

    With the JB patch being deployed over the weekend (why is it always over a weekend anyways?) hopefully someone will make some progress on those files so you can revive your phone. :(

    I too have bricked my D4. Took it to Verizon and they say that they have never seen it but someone saw a youtube vid of the logo screen spinning for hours.

    Which mine did after the update. After 2 hours of spinning I figured something was wrong.

    New droid tomorrow :)

    Ignore my stupidity. I should have seen this earlier... Now what to do.. this phone is only a few weeks old due to a battery issue..

    Keep the few weeeks old phone, reset it to default .. and then root it again, reset up.. or wait for phone tomorrow, and do all of the above without having to worry about reloading it :)

    use the old one cuz most replacements suck. if the new one looks better use the new one as long as its free.

    Yeah it's free becuase the warranty is covered becuase VZQ believes it was an error on their part with the update. They do not know that I rooted they have never checked.

    Then again, this one is a replacement too because my old one had a serious battery drain issue.

    I would keep the old one, you don't know what surprises the "new" one has.

    Going to check your links now... see if I can revive this brick. Thanks in advance!

    Bought my phone a month ago, used on eBay (no one carries the D4 in Canada). Don't imagine Verizon would honour me with a replacement... maybe it's worth a try if I play the "your update killed my phone" angle too? Maybe that's plan B next time I'm stateside ;)

    Done! I'm back on the map with a working phone (yippee!) and hoping a reboot will solve the keyboard shift issue I'm having. Now off in search of a way to root from JB.

    ThankyouThankyouThankyou! (is there a way to thank in here, or to mark the thread as solved? please excuse my ignorance)
