I followed the instructions here: http://forum.xda-developers.com/show....php?t=2301259
And everything worked as expected, except the verizon logo hangs at first reboot after Odin reboots it. MD5 hash checked out fine for the VRUAMDK_NoWipe.tar.zip. The baseband that showed before I did this (which was rooted with Hyperdrive ROM loaded showed I545VRUAMDK, so I assume I have the right file. Unzipped .md5 file two different times on two different attempts to flash with ODIN (successfully...except verison hang).
I can't seem to find anything via search, hoping someone might have some thoughts.
Thanks a ton in advance for any help!
