I had same issue, ended up rebooting the box, then it started on step 2 and finished shortly after.... They were going to send an engineer round on Thursday, but he would have only done the same, and I wasnt going to leave it on!
Welcome to the Community!
Sorry to hear you're having TiVo® trouble.
If a mains reset hasn't resolved it, we'll need to send out a technician. I've sent you a private message (purple envelope at the top right of your screen) so I can arrange an appointment.
Look forward to hearing from you!

Has the software installation managed to go any further since your post? If not we may need to send one of the team out to you to check it out.

Glad to hear you managed to sort it out!
Some times the updates can take a little longer than usual and, in some instances, they need a little push to help them along!
Give me a shout if you get any more issues.
All the best
