No, sir. You need root to flash a group Rom.
Hmmm, froyo was changed to group by the phone.
Mmmmmmmm well when i rooted my phone i lost some apps such as fandango and radio time, n for some reason i cant find them anymore on the market, soon i will change my 8gb card to a 32gb, so i also need to format it, i think that i will unroot it n get my apps back n back em up, if the evo was rooted before its release im sure 2.2 will b rooted wittin d next week, much respect to d developers. Thanks yall
