and I found that the Google Play Service Error STILL EXISTS!
no matter what Gapps I installed (Gapps on post #1 or PA-0-Gapps), if Google Play Service updated to 7.5.74 itself automatically
the Google Play Service Error will occurs...
But after I apply this fix I found on Xperia Sola board
then everything works fine
and I think this solution is easier then the solution on port #810...
