My bb 8700g, after wallpaper inst, comes out and doesn't loads OS (is resetting by itself). No connection may be used for remove/clean/upgrade SO. Last solution is a hard reset (i think), but nobody knows how to do it: somebody says to use ALT+CAP+DEL during start-up, somebody indicates a reset switch under battery (?), sb says to take out the battery during start-up... no solution was googd.
Does sb knows how is possible to reload (new) SO, out of usb connection?
