Help needed with a console stuck in update mode (error su-30677-3)

Hi everyone, I hope this is the right sub, if not do tell me which. I am having the error su-30677-3 when updating, console struck in update window and reboot and turn off. I try every option in the safe boot menu ( update from pen drive, from internet, restore to default, rebuild database, initialize, initialize from pen drive) nothing seems to work. I am really close to take out the drive make a format in a PC and see to start again. Any help? Thanks!
