Hi!My problem is a bit more complicated. I have a bb 8520 that shut down by itself but it never starts again, so the screen stays always black, with the red flashing light blinking 5 times continuously. So I can never get apploader to recognize it, nor does bbsak.I installed a new os a few days ago, that might have caused this. Any suggestions? Waiting for your reply.p.s. this is the os: 8520wifijAllLang_PBr5.0.0_rel1831_PL5.2.0.111_A5.0 .0.1106_AXIS_Indonesia
