so i've gone through these steps pretty religiously 3 times, and each time seems to be elongating the time between boot, setup, and eventual reboot. the last time I thought I licked it, but sure enough it started the rebooting again and even went into a period of rapid bootlooping. (!?)
This is really weird. I think its a problem with the actual network adapter. Everytime I start to enter my wifi settings (specifically entering my proxy/static IP) it freezes and reboots.
Im just going to take this thing back to the store tomorrow. I love this phone and Im sure this is a fluke.
Again, thanks for your help, bros.
