(after careful searching of the archives) I still need some help.
I purchased a used M8 on swappa.com (not finalized yet, still haven't been able to boot the thing).
Was running Viper but couldn't boot past init screen - kept giving sense errors. so... I tried a couple of other ROMs loaded via SD-card (CM, Android Revolution) and both seem to install, then nothing. Reboot and only a faint gray screen. Unable to sign in. I can get back to Recovery but if I don't hold the down-volume at startup I get back to that faint gray screen.
Does OS- mean no OS is installed?
