My dad gave me his old Xperia Play phone. And it had a lot of tihs in it. So I "cleaned it" by restoring everything. And I can no longer download stuff from the PlayStore. It says that it failled restoring some server information and no it does not appears any Error number. Also, I remember that my dada had android 4.x on it and now I have android 2.3 and it wont let me update it to a newer version because it says that its already updated. So basically... thats the main problem. Any way to solution?
