I flashed ICS on my SGSII like 1 or 2 weeks ago it was working great, even Android Market updated to Play Store and it was working OK.
My SGSII is International Version, not locked. It's not rooted. Bought in Dubai, got to change the Sales Code to UK (UAE was not available since it was a European ROM?) when I flashed with the ICS.
Last night (23rd March 2012) I was trying to download some free apps from Play Store App and it was displaying Error -101, for several attempts and for different apps. Keep in mind that yesterday I did not use Play Store, also the system did not update anything during the day.
Tried Clearing cache and data of Google Play/Market.
I got the screen that says Android Market is upgrading to Google Play.. blah blah blah.. press continue
But then after that now Play Store is not connecting, it says Server Error, with a Retry Button.
Tried again Clearing cache and Data... no success. Same Server Error.
Restarted the phone... no success. Same Server Error.
Tried deleting my google account and enter it again... no success... and guess what? Same Server Error.
This started approx @ 1900-2000 GMT +3. Let's see if tonight it fix by itself (but I don't think so, since the 24 hrs ban due to excess downloading from the Store is dismissed).
Any ideas how to solve this?
