Hi everyone,
i am new to android. My bro's HTC hero is running software version: www.HiAPK.com 1.0_g3_sense. It is a custom room I guess after google around. Now I want to update to 2.1 Eclair where i download it from HTC webpage. After searching around I dont really understand how to flash or root the phone o.O

My question is can I straight away update to that version of do i need to restore back to original version( 1.5 cupcake) and then only update to 2.1? Does Nandroid back up the contacts too? Or just the software only. Can anyone help me here?

Thanks

No one can help me?
