The old one is rooted and has a 32gb microSD card. Both the old & new are running 5.7.906
The one thing I haven't done yet is activated the new phone (did the four corners green guy skip). The SIM card is not inserted in either phone at the moment. I'm loathe to spend the likely HOUR on the phone it'd take with Verizon and then if the new phone "doesn't work" I'd have to do the dance all over again. Let me get the phone set up first...
I thought I was headed in the right direction by first rooting the new one (via the motofail method) which seemed to work. I then bought and loaded the $3 CWM tool. I used that to create a backup on the old phone to it's SD card. Also, seemed to work. Also downloaded the CWM app onto the new phone, powered off, brought the SD card over, powered up, used the app to reboot into recover and reloaded the backup. Seemed OK. Lots of stuff 'looked like' it was present and usable. I wanted to then go and whack out the bloatware.
But now the new phone reboots. Not right away, it takes a few minutes but then, with no messages on the screen, it just spontaneously reboots. It only seems to do this if the USB cable is connected and USB debugging mode is selected.
It does not reboot unless USB debugging is enabled.
Ok, so perhaps I've missed some critical steps or something. It's been a while since I had to do this sort of thing and this is a pretty old phone. I'm inclined to think there's and ADB driver issue here. But I'd like to be sure to head in the right direction before making a bigger mess.
