For those who rooted but are still locked, and having issues with updating, here's something that might help (continuing from: http://forum.xda-developers.com/show...ostcount=111):

There were 3 files missing from /system/xbin that were required for the update to work.

Missing files:

Downloading and will add a Mediafire mirror as soon as I can.

Here's what I did, from beginning to end:
  • Extract the above zip and put the three files on the main storage.
  • Copy the dlpkgfile to the main storage
  • Enter shell:
  • SU
  • mount -o remount,rw /system
  • cp /mnt/sdcard/dexdump /system/xbin/dexdump
  • cp /mnt/sdcard/ps3bttest /system/xbin/ps3bttest
  • cp /mnt/sdcard/rfcomm /system/xbin/rfcomm
  • chmod 777 /system/xbin/dexdump
  • chmod 777 /system/xbin/ps3bttest
  • chmod 777 /system/xbin/rfcomm
  • mount -o remount,ro /system
  • cp /mnt/sdcard/dlpkgfile /cache/dlpkgfile
  • echo '--update_package=/cache/dlpkgfile' >> /cache/recovery/command
  • Exit shell.
  • Shut down tablet.
  • Turn on while holding the "volume down" key.
  • When it vibrates, release the power key and keep holding the volume key.
  • Three lines appear, hit "Volume UP".
  • Update starts!
  • Update Finishes!

Note: some users reported success after replacing the build.prop with the one attached here (ripped from the .28 blob).
