I used the advice in post #21 but did not follow those instructions specifically.
Here's what I *think* I did:
I followed Mareks install instructions (post #1)
Then I went to settings >> autostarts
During startup: I enabled google services framework
After startup: I enabled gmail & the x4 google services framework
I then rebooted & then it finally allowed me to get play access & sync gmail etc...
It seemed to work after that. I did not bother with moving accounts db etc...
Hope that helps??
