I like the 712, it has very nice hardware but it seems that the software isn't quite where it should be. Thus the issue. My Play store didn't work at all. First thing I did was to surf the net but couldn't find answer. Then I looked up most recent firmware for my version from onda.cn (1.5 for V2). It didn't install from the zip straightaway (signature failure) but when I unpacked the files to SD and updated from those, it did update the first zip but the second (patch.zip) failed with aforementioned signature failure. Result: tablet still works but I lost ~70% of all the applications and who knows what else. Most stinging loss was Play store. I tried to sideload it with the framework from the package but it seems to require something else from the update as well to work. Questions: Is there a working firmware somewhere? I will yet try with 1.4 but the download is horribly slow. Is there some other recovery tool so that I could ignore the signature error? If everything else fails, how can I get the Play store to work? Thank you. ------------------ Update: Installing the 1.4 firmware first solved the problem with the missing applications. 1.5 update still doesn't work.
