I have a 2 yea old Bolt + that got the 4 LED Flash last week. I'm attempting to install a new drive without copying anything from the old drive (since it's dead). Although I was unable to find a thread about this use case (there are many about migrating data from driveOld to driveNew) I got the impression that all I needed to do was install it, the bolt would recognize the blank media, format it, install the tivo OS and I'd have to set it up again. So I booted the device last night and turned off the display so it could do it's thing overnight. When I check this morning, it was still at the grey "Starting Up" screen. I thought maybe it needed a ks52, but it also doesn't seem to progress past the grey "Starting Up" screen. This device had been using MoCA before for network, so I connected an ethernet cable, and tried ks52 again, but it still doesn't progress past the grey "Starting up" screen. Does the drive need to be formatted via MFSTools first? Anyone who knows the correct steps here or could link a thread that does, I'd really appreciate it.
