Similar tragedy here! Last saturday I just left it to die without battery.. As Sunday came on.. no sim at all!
Many reflashs later (with different fws), not much has changed. (It "worked" for less than 5 mins this morning after reflashing with the global (2.2009.51-1). Now I just reflashed again and am trying to do ALL the updates from scratch!

But yes... picture a pissed off fella, that me now!
I'll report if I have news.
PS: despite this post being totally NOT informative, I feel like it may help someone in the same situation to feel a little less "alone".
