Oh heck, I forgot that!
Scary wrote a little app that would start on boot and fire up another app - search "AF Rescue
" in the Play Store. The original version would try to launch WiFi File Explorer, and I'm sure that wouldn't let you access the SMS database, but I knew there was a second one
, and I've just checked and that one will try to launch MyPhoneExplorer client, which if you can start it up might be useful here (at least from the not very detailed description on the Play Store). Might have been worth a try, though I guess too late now
