After this heavy registration process, I achieved to access this forum ;)

I have GY-521 now working.
In the beginning I ran into exact the same problem, but it was because I had cleaned the eeprom before. (Due to some other problems)

One click on „CALIB_ACC“ an everything was fine :)

Hope this helps someone with the same issue.
