Fortunately, reinstalling the software is not that hard. I've included instructions below for reverting to an older version, but it works for the the current version.
You just have to download
from CM's web page: http://support.channelmaster.com/hc/...oftware-Update
, and put it on a USB stick (should be an empty stick, and should be formatted FAT32).
That said, you could try forcing the DVR+ to reinstall version
using your Ethernet connection on the DVR+. Steps "g" and "h" (see instructions below on installing an old version) describe how to force the DVR+ into a Maintenance Reset (probably what you were trying to do by holding the power button and connecting power). I just did those two steps (without a USB Stick), just to see what happens. I left the WiFi dongle plug in, and the USB HDD connected, and after the DVR+ complaining a few times (I just let it go) it finally got a Internet connection and downloaded the current software.... The "update" completed without issue (about 10 minutes), and when the DVR+ rebooted, and went though the sequence you've described, plus the grinding gears image I've described, and stopped with the unit in Standby Mode. Since you're using Ethernet, yours should be much smoother and faster. I would definitely give this a try before boxing it up for return, unless you just don't trust the unit. If you have any trouble without having version
on a USB Stick, I'd download that version, put it on a Stick and try it that way. For anyone else thinking about doing this, the device did NOT lose anything (the Rovi Guide, the Recordings, the Recording Schedules, etc are all unharmed).
Installing an old Update (should work just as well for the current version (
- Installing an old DVR+ Software Update is not a straight forward process, as the DVR+ will reject it in favor of the installed version. But it can be done, following the steps below. This procedure has been reported to successfully revert from DVR+ version 124R to 114R, and 111R to 108R, so is likely to work in all cases, at least through DVR+ version
124R 135R. I believe it was AVS Forum member rbpratt541 who first described this procedure in an AVS Forum post on 11/12/2014 at 10:37am (central). Thanks rbpratt541! I believe this has been referred to as a "Maintenance Reset".
Of course, you'll need a copy of the old software, and hopefully you have it in you private stock somewhere, a really good practice since CM removes outdated versions from their web page as soon as they post the newest version. If you don't have a copy, an AVS Forum post on 06-11-2015 at 7:42PM (central) has a link (to the host dropbox) where many versions can be found. The link opens a Dropbox page with links to many DVR+ software updates. If Dropbox asks you to sign up, or log-in, you don't have to do that, just click the "X" button on the popup to close it, then click on the update you'd like to download. If that's no longer available, search the rest of the Channel Master DVR+ Owners Thread. If still not found, post a plea for the needed version and maybe someone will be able to help.
- Ensure a USB Thumbdrive is formatted in FAT32. Other formats will be rejected.
- Copy the older software update onto the Thumbdrive. It MUST be in the root directory, and MUST be the only DVR+ update in the root directory.
- Put the DVR+ in Stand-by mode (dim blue light).
- Unplug the power cord (or power supply, whichever is convenient). In a few steps, you'll have to simultaneously restore power and press a button on the DVR+, so keep that in mine when deciding what to unplug.
- Unplug the WiFi Adapter, or Ethernet cable, to prevent Internet access, and unplug the USB HDD. The HDMI cable, and Antenna Lead can remain connected.
- Plug the USB Thumbdrive, containing the old Software Update, into the DVR+.
- Depress and Hold the front panel button, and restore electrical power.
- The front panel light will flash blue, and red for a second. When the light goes out, immediately release the button, count 3 seconds, push the button again, and release.
- The TV should show the update in progress.
- When done, the DVR+ will restart automatically. The screen may go black for about 15 seconds, so be patient. Note: It has been reported that this sometimes fails. If that happens, connect the Thumbdrive to a computer, check for a folder named 'core dumping', and delete the folder. As already mentioned, ensure the Thumbdrive is formatted as FAT32. Repeat the process.
- When complete, remove the Thumbdrive and reconnect the USB HDD (both can be done while the DVR+ is powered), and follow the instructions to reconnect the USB HDD.
- Reconnect the WiFi Adapter, or the Ethernet cable, and follow the on screen instructions to get Internet communications working.
To prevent the DVR+ from eventually forcing an update to the current version, the DVR+ must be denied access to Internet address tr50.dishaccess.tv
. That's done in your router's software, which varies from router to router.
