My solution was for htc sensation only. Dunno about the nexus, sorry. Tried to modify the framework, but that didnt work, so flashing the non multi framework-res on multi and its a good to go.
Miuiandroid multi htc sensation bootloop solution:
1. Use framework-res.apk from normal none multi rom. It will then boot and still be multi. The included in rom has bad faulty compile.
