Hey... Experimenting with different Roms right now to see which one I like best... I started with Sholes/DM... Then recently downloaded Rom Manager and installed Cyan/Jrummy's newest (which was really nice looking.. but lagged on my phone), then used Rom Mgr to install BB1.0 with smoked glass. I just installed BB over the Jrummy with no issues. BB is pretty awesome, blazing fast, but kinda plain looking. Wanted to try some of the other Roms on Rom Mgr. Tried UD and RedRum and they both gave me errors when trying to install... I don't get past the 1st portion, it doesn't even start to load.
I believe its due to me just trying to write Rom after Rom on top of each other. I don't know if I just got lucky going from DM->Jrumm->BB... I wiped data/cache only once (between DM and Jrumm). The question is.. Do I need to use Rom Mgr and revert to stock or something to try something else? Or do you think the last few attempts failed because I didn't wipe data?
