I just bought a new tablet, Prestigio Multipad, creat google account, connected to Wifi and when I want to download something from Android Market it always says "Download was unsuccessful. Please try again." How to fix that, what's the problem? EDIT: I did factory reset, still the same problem. Can't download anything since bought it. EDIT2: It happened probably because I updated Firmware. I saw that some person had also the similar problem after upadating it, but that person wrote: "just reflashed to F7 rom then at the option i chose clear partition cache and also clear all user data etc, basically the phone booted as it came out of the box..." I do not understand a single word what that person wrote (flashed to f7 rom) so can somebody explain please!
