Advertisements Hello. When I purchased my used Tivo bolt, it had all flashing lights and was told by the seller it was a simple hard drive failure. I replaced the hard drive with a normal size 3.5 inch 8TB hard drive vs the laptop hard drive that was there before. I followed whatever steps you are suppose to do and it sort of works. The problem is that even so often all the lights start flashing again and it requires me to just reset the device for it to start working again. Sometimes it has gone as long as a 2 weeks on its own and sometimes its a little as 1 hour. Eventually the lights will all start flashing again. Does this sound like maybe a bad SATA cable or firmware on the device itself? It sort of works but has become very flaky from day 1. Perhaps the ebay seller was trying to sell a lemon of a tivo. Please let me know if there are any troubleshooting steps I can take to try to pinpoint the problem? Thanks.
