ok, so I've been running 1.7 for the past two weeks or so, but I've had to data wipe and reflash 1.7 last saturday after my messaging was force closing and I couldn't get it back up by wiping cache nor fix permissions nor re-flashing das bamf on top of it. today, I rebooted since I was getting data errors and once it booted back up, messaging and phone are force closing, with the phone in a force close loop and the data doesn't seem to be working. I tried fixing permissions, wiping the cache, re-flashing 1.7, and re-flashing the radio, but no dice. any ideas what could be causing this or what I could do to fix it besides data wipe and reflash?
i would try reflash with multiple (3+) wipes of data, cache, and dalvik if you really want 1.7, otherwise i would just revert to 1.6.3 which was pretty much bug free.
