Legacy DCX3400/3500 constantly rebooting - FIXED
I have had 2 of these now-legacy DCX3400/3500 series DVR’s for close to a decade. One of them started rebooting nonstop on 9/2/21. I figured I would resolve it with a replacement. Not so much.
Short story: after 4 replacement DVR’s and a tech visit to resolve “signal quality in the home” (no changes to our wiring in 10+ years) - all DVR’s continued to exhibit the SAME PROBLEM: after working normally for 2-4 days,
constant reboots (88:88) immediately after starting to update/download (sync activity indicator) and reset to the current time - BOOM - reboot.
I have lost every recording on each of these DVR’s and not had use of my media room’s DVR in over a MONTH! While a 2nd DVR in a different room kept humming normally, as did our Extreme Internet service, and a digital receiver at the same location reported good signal strength (even on a splitter!)
I’m told that I have a level 4 support ticket that has elevated priority - but no call in a week, with a stated 24-48 hour callback window.
I hope to save others some pain by sharing this link to the DVR CLEAR procedure that I used to finally STOP the reboots (stability day 6).
While I am grateful to be able to keep using this legacy DVR equipment (past bad experience with IPTV), something has to change with the quality of the updates - or tell customers that you are no longer supporting the old DVR’s so we can make the decision to find another option for stable service.
Thanks for reading.

Hi there @DavePi99! Thanks so much for taking the time to reach out to Xfinity here on our Community Forum! We are so glad to hear from you and ready to assist with this in any way that we can. Generally when the legacy devices are being phased out of rotation, customers are notified months in advance. There are materials enclosed along with billing statements along with emails as well. Now that you have replaced that device, are you still having issues?

@DavePi99 Any resolution from tier 4? Been experiencing the same for 4 months now with the only solution each time being a box wipe.

Thanks @SammyFL and @Keloms for responding. Glad to know that I am not alone with this rebooting/stability issue.
Sorry for the late response, I JUST received notification for responses. Forum notifications are one more thing that’s broken, I guess.
On DVR#5 now. After the Advance Team sent multiple codes, the DVR was stable for almost 1 month - (edited: language) out 3 days before Thanksgiving ( that’s 3 holidays where my media room’s DVR was dead, for those keeping score).
Then it happened again. Both of my DVR’s had lost the list of their recordings. My bedroom DVR rebooted fine and the list of recordings was restored. Media room DVR started its continuous reboots. Again.
I had requested that these codes to fix these DVR’s we’re added to my resolved 10/29 ticket. Apparently, this was not done, as no-one I’ve talked to in support has indicated they show anything in the notes.
Still waiting for the advance team to respond to ticket #4. I am trying to keep the recordings this time, so not running CLEAR or swapping out for the new DVR (#6) sitting on my porch.
Does anyone have a way to get a hold of the advance team directly ? Sitting and waiting forever is unacceptable.

@SammyFL Good catch on new firmware. I had suspected firmware from the get-go.
Do you know which option has firmware on the diagnostics menu? (Power off DVR, Ok)
I have limited time between DVR reboots, so appreciate where to look.

@DavePi99 Thanks for the update!
Unfortunately it doesn't appear that the SW version is in the diagnostic menu from my checking.
For comparison, my box is on the A32.2103.r-2 version.
After the latest box wipe, I recorded a quick 5 minute clip and did a manual power reset to test if it happened again right from scratch. This time the box powered back on fine without a reboot loop so it appears that the error isn't automatic but rather that there's something that happens over time that causes a reboot loop following a crash / power reset.

@Keloms thanks for reporting your firmware version. I’ll try to check the rebooting DVR for a match.
I was seeing the same thing with DVR stability changing over time, which still seems to me is either firmware changes or corrupted code elsewhere (guide).
Every time the update indicator flashes, I brace for more reboots. Crazy that this was distro’d for a “supported” box.

Updating: still no call from my advance team ticket.
Wow, that is really POOR customer service. In one of the many chats with technical support, I had specially requested adding text on the advance team ticket that a CLEAR fixed the problem, as only 1 item indicating a firmware problem. Apparently, I was just ignored further.
However, we had a second technician come to the house last week on 12/3. He did 3 things: 1) confirm a good signal to the location with the trouble DVR, 2) found and removed a duplicate line filter at the Comcast box outside my house, and 3) replaced the last DVR, as it was still rebooting even with the line filter removed.
This latest legacy dvr (#6) is still operating normally 1 week after the appointment. Monitoring to see how long this one stays online.
second technician come to the house last week on 12/3.
Additionally, I received confirmation that Comcast had implemented the September firmware update - to INTENTIONALLY kill the legacy DVR’s. I am not clear if they had *intended* to kill ALL legacy DVR’s, or just the ones being used illegally, but they’ve succeeded on both fronts.
Comcast: if you want to desupport these legacy DVR’s, please do it and stop the pain. Otherwise, please FIX the problems - and get your advance team to actually CALL people back (especially when a very techinical resource like myself can provide you additional troubleshooting detail to help guide a solution), and so that your customers… will actually *remain* YOUR customers (I am personally Comcast class of ‘93)
