tried this with many different roms ranging from the original stock rom to custom roms in recovery, it says installing, but one second later it finishes and when i go to reboot it says "no os installed" nothing will install correctly. Even tried to install all these in .tar files thru odin and every single one fails every time. Ever since the first rom failed thru odin i cant even get into recovery anymore.. when i go to get into recovery instead of loading it the phone just says "firmware upgrade encountered an issue. please select recovery mode in kies and try again." Usb debugging was never checked before i lost my os, maybe this has something to do with it? So now that i cant get into recovery and odin always fails how can i install a rom? Even tried to reinstall a recovery thu odin and that fails aswell.
