The weirdest thing happened to my brother's bb 8310 he had it in his pocket one day and when he came home it didn't work. So he gave it to me and I've been trying to get it to work but it seems impossible! I've tried everything. It constantly disconnects from every PC I connect it to. The phone keeps connecting and disconnecting automatically from the, now, 4 computers I have tried. The beep you hear when you plug it in and out keeps happening every 30 or less seconds. It also gives me this message: "Unable to reconnect to the device during a multi-stage load operation" I tried typing "START" and it doesn't work. MFI Multiloader, Jl_Cmder, Desktop Manager and Apploader give me an error message, it seems everything is working fine, until it can't connect. Any advice? Magic? I'm about to give up
