Hi i am running the r12 dont think that matters but. I forgot to plug my phone in last night. I had 30 percent battery so i plugged it into my car charger. it shut off and now wont turn on at all. I have pulled the battery about 50 times with no luck. I plugged it back into the car charger the wall charger and my computer still nothing. I tried to turn it on into the download mode my computer didnt notice it. I have pulled the sims card the sd card nothing. Just a black screen. I now put 2 and 2 together. this happend before about a month ago but then i pulled the battey and it came back on. Now if i get it back on I know better than do it again. Is there anything I can do? I am thinking about stopping at tmo tomorrow to see if they have a battery to try? Has this happened to anyone else if so what did you do?
