    I have a Roamio Pro with stock HD (high mileage/tons of recordings) that is refusing to roll-back as other have reported here. I follow all the outlined steps but after pressing rewind twice it immediately goes to the black arrow screen - then after a few second reverts to the guided setup options.

    Based on the latest posts, it seems folks are attributing this to a fragmented or otherwise hosed up HD - is that correct? How was that conclusion reached?

    I don't care about my recordings/OPs and am totally comfortable pulling the drive (been hacking on TiVos since DirecTV days) and giving it a low level reformatting but want to confirm if that is truly a solution to the "won't roll-back" issue...

    Appreciate any feedback here...

    I did a online chat with TiVo customer service several weeks ago; as soon as I mentioned this forum and that a few others had the same problem, they told me I needed to email customer service instead as it sounds like a software problem.
    I emailed customer service, got their automated reply that they had received it... and haven't heard anything since.
    I also don't care about my current recordings, I just want to get back to the old format. If/when I ever hear from TiVo, I'll post here.

    I also have a romio pro but I recomend pulling the recordings using tivo py or kttmg first. Off of the drive and the romio pros came with a 3tb western digital green drive which are no longer made. So you have 2 options here. After pulling the recordings.
    1 replace with a 3tb red plus drive or purple drive that's brand new.

    Or 2 go with a 6tb or 8tb red plus or purple drive and see forum mffs reformator, and follow instructions in that post after sucessfully rolling back.

    But I have a question first do you have any other hard drives lying around that are unused if so you can try using them just if they are 3tb and under and let them auto format then try performing the rollback procedure or if you have a staples or a best buy purchase a blue laptop size drive 1tb drive lay it gently on top of the stock drive gently with the case off let it auto format go through guided setup and then perform the roll back procedure again, and hopefully it works, then go through what I outlined above.

    I am just glad I got my permanent rollback done in January.

    The issue I think appears to be heat related on the drives with the hydra updates, and just for a for warning te3 seems to be doing some of that also so you might want to consider installing hard drive heat sinks on the new permanent hard drive if it will fit between the screw spaces for the hard drive.

    I also have been toying with tivos since 2015 I bought my series 4 in March 2013 and then in September 2013 bought my romio pro brand new but in 2015 did my first bigger hard drive first in my series 4 using jmfs then 2 months later with a 6tb green drive in my romio pro using mffs reformator I have also used mffs reformator for my bolts.

    In my case with the romio I regretted upgrading to hydra.

    I have a question for you on your romio pro are you using the stock 3 tb or an expanded drive of 4tbs or greater that has been reformated using mffs reformator.

    If the later is the case you need to put the stock drive back in then perform the rollback procedure cd and e and rollbacks will not work on hard drives bigger than 3tbs in romios or bolts trust me I tried that in my romio once.

    Hope that helps.

    You could also try a cd and e or clear and delete everything cycle with the stock hard drive in go through guided setup then try the rollback procedure again, then after choosing a new hard drive then install it in the tivo.

    Correction, the DVR in question is a Roamio Plus running the OEM 1TB drive. And again, I don't care about the recordings or one-passes - I already tried a C&DE so all recordings are gone already - but roll back still does not work. I have been running this box in stock configuration since 2013 with no over-heating or other issues. Mostly looking for some clarification on why formatting the HD would resolve the issue with not being able to roll back...

    I got a WD Purple (1TB) for my Roamio OTA (original 500GB); put it in and it automatically installed the new menu/guide! :( I'm wanting to rollback to the old format.
    I also tried the rollback method (Help/Repeat Guided/2x thumb down/2x rewind) and it brings me back to the 'Reset to Defaults' menu.

    Any other ideas?

    One possibility is that you might need to toggle your remote to IR mode (or use an old TiVo IR remote).

    I tried an older remote, plus a newer remote; neither made a difference with downgrading.

    I called and spoke to Tivo tech support, guy insisted that my 85% wifi signal (Network Status) was too weak to downgrade (yeah, right). He wanted me to install the Tivo to the modem via ethernet... which I did and of course it made no difference, I still could not downgrade.
    I replied back to Tivo support via my account Support ticket, haven't heard back from them in 3 days.

    In the meantime, I bought a used, but slightly newer (March 2016) Roamio OTA 1TB and was able to roll that back once I cleared and deleted the previous owners info/recordings. Once it rebooted and I went through the Guided Setup, it upgraded itself and rebooted. Upon reboot I had to do the Guided Setup again, and then was able to downgrade (and another Guided Setup again, lol). And BTW, this was done with a "77% Network Status".

    I cracked open the case and tried to install my original (February 2015) Roamio 500GB hard drive that wouldn't downgrade into the newer Roamio. The Tivo box recognized that the hard drive had newer software and I got a red screen about calling Tivo to downgrade my (software?). Put the 500GB back in the 2/15 machine and did a 'Clear and Delete Everything'; put that back in to the 3/16 box and got the same red screen. Could not click out of the red screen. (Repeated this same situation with the new WD Purple 1TB HD (see my April 16th post) I had with same results.)

    So, it seems that the software/firmware version is stored on the motherboard. Do you think if I removed the button battery overnight will make a difference?

    The OS on the motherboard is stored in NAND memory, which doesn't require any power.

    UPDATE - finally got the Roamio to downgrade to Quattro! :):):)
    and I was able to accomplish it via their Support ticket in my account (I hate sitting on the phone with support people).

    This is what I sent to them (after the 3rd time of them telling me the downgrade process):
    "I have attempted the backdoor downgrade multiple times without success.
    The TiVo looks to be running a hybrid HYDRA-MIRA software, instead of just HYDRA that might be the problem:
    Date of manufacture: 2/2015 (500GB)
    Software: 21.10.2.v13-846-6-846
    TSN: 846-0001-xxxx-xxxx
    HD menu software version: b-hydra-mira-4-11/2021.02.22-2053
    HD menu client core version: b-clientcore-mira-4-11/2021.02.22-0800
    Is it possible to push either the Quattro or straight Hydra software to my Tivo box TSN: 846-001-xxxx-xxxx?"


    Tivo tech support emailed me:
    Please restart your box and reattempt the backdoor code provided on our previous email sent to you. If all troubleshooting steps have been performed and the issue persists, proceed with Technical Phone Customer Support at 877-367-8486, for more troubleshooting.
    Next support should know where we started and left off using case number above.
    To respond to this email, please log into tivo.com/myaccount, go to the My Support tab on the left, and select Case No.: 000000


    I manually did a Network Update and immediately (without restarting the box) tried the backdoor downgrade - and it worked!

    I did this with my original 500GB HD, it won't take the newer 1TB HD because the Tivo now has Quattro and the 1TB had the Hydra-Mira. So now I get to figure out how to clear and format the 1TB to try that over again (oh, joy :eek:). ETA: hooked up the HD with my USB adapter, and did a clean/partition/format via DiskPart (DOS).
    The (2016 replacement) fan started screeching upon startup, so I tore that apart to oil it for the time being while I order another replacement fan.
    Such fun :confused:

    Thanks all for the help, and I hope that this also helps others looking here!
