I have asked this question on other forums and have not been able to get anywhere. My Droid 2 lost it's USB interface (no communications, no charging of the battery, nothing!) and I want to get the stock firmware restored before taking it in for a tech at a Verizon Wireless store. Before anyone asks, I have tried everything including clearing the phone cache and system data, new cables, different host computers, power adapters, etc. in an attempt to get the USB interface working. It is completely unresponsive to all attempts to revive it. I have searched all over the Internet and forums for an update.zip file that would restore the phone to Froyo (either 2.2.20 or 2.3.20). Can anyone help me locate that or let me know how I could create one from the SBF's. I really appreciate any help you can offer. I am limping along now swapping batteries and using an external charger to keep this phone alive. Thanks, Dave G.
