Hi pearce

First thing you need to check is go to App manager open it then choose options, then settings and check that Software installation is set to All and Online certificate check is set to off.

That should help but with some apps there certificate is now more than a year old so has expired so set your phone's date back a Year and then after successful installation set i back to the correct year.

I hope that solves the issues you have been having.

If the cert has expired, just re-sign it yourself again.

Or look at the timestamp of the signed file and set your date accordingly on your phone, then install :-) No need to resign.

There is a handy little application called "Mobile Signer" from - works as advertised and saves loads of time, can sign things directly on your phone.

Edit: Reading Chinese is probably handy for the above link. Or you can get it from though I think this is a slightly older version that doesn't quite work, look for V1.03
