That's it Ioan Florea! I had 6 parts(resistors and capacitors) ripped off and stuck to the insulation sticker. After a master soldered it back(for $17) all works again. Hooray! P.S. I'm pretty good with soldering iron, but this parts is too small! Without microscope I could nothing to do with it(and don't advise to you). P.P.S. Don't try to hook up the battery from side of charging and dock flex cable connectors!!!
