Called TiVo today and they suggested KS 57. They say they can see the device requesting the update. I explained to them what happened so far: TiVo has been in storage since ~2015 but just got a second TV. Device was working fine, but guide info was out of date. Went through guided setup but device now reboots on “Preparing to Load”. Now stuck in GS mode. They also suggested KS 720 but I can’t find anything about this. Anyone familiar with this KS code? Thanks in advance!
