So after spending an excruciating 3 days with the Hydra UI on my Roamio and 6 Mini's (and with nasty family feedback), I posted the request to rollback on the Tivo forum site. I was sent a message to contact Tivo support directly to find out how. Tivo support was very helpful and gave me the following instructions which they OK'd for forum posting. KEEP IN MIND YOU WILL LOSE EVERYTHING!!! For the Roamio: 1.) Go into Menu- Help- Reset to Defaults- Repeat Guided Setup- Select 2.) Press Thumbs Down 2 times (NOT 3!), now press Rewind 2 times, Now press Select (not Enter) 3.) Roamio will immediately go to that right arrow screen, then screen blank, then you'll get a message letting you know that the rollback process has begun All in all, the rollback didn't take more than 10-15 minutes HOWEVER once complete and finished Guided Setup on the Roamio, if you have a MOCA Mini network, you'll want to go straight into the Roamio and enable the MOCA Bridge option right away before the Roamio dials back in a 2nd time as that process tied up the Change Network Settings option for a couple hours in my case (YMMV)! For the Mini's v1 (but I'd guess v2 is the same). Also note, I waited til the Roamio had completely rolled back and I completed Guided Setup before starting this process: 1.a.) Go to Menu- Help- Repeat Guided Setup- press Thumbs Down 3 times and press Enter. OR 1.b.) You'll already see the "downgrade" screen and it will prompt you from there. 2.) You'll now see the "old" Guided Setup. Go thru that so the Mini can phone home. 3.) The Mini will phone home and prompt you once again to go thru Guided Setup. 4.) After the 2nd Guided Setup completion, you should be back in business 5.) Congrats- You've just wasted a better part of a day! Note: Each time I went thru Guided Setup, my Mini would fail to connect and I would get the Network Connection Error screen (N07). Simply waiting a second or two for the Mini (or Roamio) to gather itself and retrying solved the problem 100% of the time. Overall, the reason the Hydra UI was such a non-starter for me is that the UI was just too sluggish on my entire system. I feel the code is just too heavy on the Roamio processor and I would guess it would be better on the Bolt. I found the lagginess caused me, and I'm being literal here, a bit of almost anxiousness and stress- it was just that poor performing. With that said, someone else did report they were happy with it on the OTA Roamio- I would guess that's due to the processor workload compared to my cablecard version. Also- and this was just as important- for whatever the Replay button no longer functions as a alternative Back button. This was posted BEFORE I "upgraded" and I honestly wasn't sure just how critical that darn button was- it is VERY important- especially in the My Shows or anywhere the Tivo button is used. So, as currently laid out a new remote with Back is pretty much mandatory and at $45/each for 7 units- a purchase that I'm just not willing to invest in for something (a.) I felt could be easily overcome by leaving the back function intact, or allowing thru Setup, the remapping of a much less used button. And (b.) if I were going to go that route I would prefer to just apply the funds to purchase of units that were strong enough to carry the Hydra interface. In summary- returning to the Good "Old" Interface has never felt like a better upgrade! Hope this helps and Good Luck!
