Advertisements My TiVo Roamio OTA stopped outputting an HDMI signal, and TiVo sent me a replacement TiVo Roamio OTA. Same model, same everything, except with the new Hydra interface. And I really dislike it. I tried following the instructions where you go to the screen to re-run setup and do the two thumbs down (instead of three) and the two rewind presses, and that didn't work, and I tried restarting my TiVo twice and forcing a connection twice, and then re-doing the instructions with the two thumbs down and the two rewind presses. I must have done the two thumbs down and two rewind presses a dozen times. I contacted TiVo through chat, and two TiVo CSRs told me the same instructions through chat. The first one disconnected before letting me respond whether it had worked(hung up on me), and the second one finally told me to call in when it didn't work. I called TiVo support, and the TiVo rep again guided me to unplug and restart the system and do the two thumbs down and the two rewind presses. She stayed with me on the phone while I was doing it, and the screen just sat there showing two thumbs down and never displaying anything about reverting to the old TiVo software. The TiVo rep seemed really perplexed as to why this didn't work. She went away for a few minutes and then came back and basically told me this is a known issue and there's nothing she could do, but gave me a ticket number and said TiVo is working on it. I have recordings and OnePasses on my old TiVo and I wanted to copy them over to the new TiVo. I paid for them to pre-ship the new TiVo to me before I ship the old one back, and while I get the impression that I can do that, then I couldn't downgrade the new TiVo away from Hydra. I don't want to keep the old TiVo here one moment longer than I have to and not receive the ~$450 refund for returning the old TiVo. I want to package up the old TiVo and send it back to TiVo ASAP. TiVo has really put me in a bad situation here. I was wondering: I am a computer systems engineer, and I have had A+ certification for almost 20 years. I have built my own computers from scratch(including recently) and have performed hardware mods on computers, and regularly use Linux and can easily swap identical hard drives in two computers without damaging anything. I have all of the different sizes of screwdrivers for everything from flathead, three-point, square, philips, pentalobe, hex, and security hex. Heck, years ago I had customized the software and upgraded the storage capacity on a DirecTiVo(R.I.P.) and I used to work in a TiVo call center. Is it possible to just take the old hard drive out of the old TiVo and put it into the new one? They're both the same model. Or, alternatively, is there anything I can do to force the new machine to downgrade to the old TiVo experience?
