I have been watching your rom flash vids and wanna flash my device with the energy rom. After installing HSPL and then the energy rom, am i right in thinking that if i ever want to go back to the original o2 rom that was installed on my device, all i have to do is connect my device to my computer using active sync and open the original rom file that i've downloaded from xda. its just that there is no .nbh file with the download, so i'm guessing that it cant be done from memory card on device. would installing the stock o2 rom from the .exe file on my computer remove HSPL ?
