How can I get all my files off my phone without USB
So I did manage to get it working with SSHDroid. The real problem was not what I thought it was at all.
I unplugged my wireless booster (Buffalo) and it started working. For some reason the booster blocks IP between the machines on the WiFi and the machines on the wired LAN even though they can find each other with ARP. I'm really glad I didn't start leaving a bunch of &quot;does not work&quot; product reviews.
(In case anybody's wondering why USB Debugging was getting nowhere, the data pins had come unsoldered; when the power pins finally started to go I knew what that problem was and took it into the shop to be repaired.)
