ok, 800w was acting up a bit, not sending text messages, hard reset itself, etc. So, pulled battery to get ESN to swap it to my main line for a few days of testing, but when I put the battery back in it won't boot up now. The little progress bar at the bottom just goes maybe 1/4 way and freezes.

Is there any way to fix this? Haven't watched the forums in a while, but did anyone ever find a way to flash the ROM on an 800w? Can it be done?
