I can not install anything from the Android market web site, as all the time it is giving me the error “you do have device related to this account”.
go to the Settings >
Applications > Manage applications and from there open the Google
Apps entry. There, you will see one of the options as 'Clear data',
click on that and then press OK. If you do that then it will remove the
google account information. Now to enter the new account information,
you will have to go to the Settings > Data synchronization >
Google and there it will show you the set up dialogue. Here, you will
just have to enter the account detail and you are done with that.
If none of the solutions helps you then you can go for the factory reset
of the phone. When you do that then it will ask you for the email ID.
You will have to provide the email ID that you wish to use primary
account and press OK. Once the reset get completed then you can use the
same ID to download any of the app from the android market. I am sure
that this time you will not get that problem again.
