While in hospital recently, I thought it would be cool to upgrade my ROM to a newer NIGHTLY. Unfortunately, the drugs I was being fed intravenously coupled with my aging gray matter, I overlooked switching to USB debugging mode. The updated ROM & latest GAPPS loaded fine as did wiping data/cache functions...however, nothing since has worked in terms of getting my phone to reboot in any way. It still responds to simultaneous Vol Up/Vol Dn + Start Buttons & simultaneous Vol Dn + Start Buttons commands. The procedure you describe, above, does NOT work verbatim on my Verizon Samsung Galaxy Nexus. Please advise what exactly I can do to get my phone back to some form of working condition.
NOTE: I am a double donater to you and have, I believe, the latest version of Galaxy Nexus Toolkit installed on my Win7 PC.
Thank you!
