Froyo on Stock EPF30 (Vodafone Germany)
My friend is having Nexus One with Android 2.1 update-1 build EPF30, bought in Vodafone
Germany .After following general steps to update to Froyo we get the error E:signature verification failed message as well. from a bit of googling it looks like this upgrade “only” works for build number ERE27. Is there an alternative for the phones with build number EPF30 to upgrade to ERF50 or latest Froyo without rooting or unlocking?
