Hey guys, android noob here, just converted to the Vibrant from blackberry not long ago. I was gonna try and go the custom ROM route, but i've hit a speed bump. i'm rooted and i installed ROM manager, but i cannot get it to make a backup. when i boot into recovery mode the only options available are these: -reboot system now -reinstall packages -delete all user data -delete cache data -format internal sd card i read somewhere to keep trying "reinstall packages" and that would do it, but every time i do i get this: E:failed to verify whole-file signature E:signature verification failed Installation aborted. i've tried older versions of CWM with no luck and searched for 2 hours for an answer. i'm lost. i'm not going to flash a ROM until i get a proper backup made. any insights? thanks!
