Huawei Dn370t User Manual
Lihuel Harding
I own a number of DN372T boxes - two in active use and two as a backup. Unfortunately, the HDD is dying in one of the active boxes, confirmed by SMART tests using Linux. Three of the boxes are fully up-to-date with the CS-3.8.128, MS-72.48.91, PC-4862 software, but one of my backup boxes hasn't been switched on for 4 years and is still on CS-3.6.138, MS-72.48.81 PC-4648 and I would like to update this. However, it fails to download the update and everytime I try the progress starts at 60%, doesn't move and errors.
I have only just discovered that TalkTalk cannot replace these boxes anymore, so I bought a replacement HDD for the box that needs one and am trying to use the "Internet/USB Recovery, delete recordings" to download the software, so that the box can install it on the HDD (software is stored on partition 1 of the HDD, as is plain to see from a partition editor in Linux). However, this download also fails. Swapping HDDs between working boxes also doesn't work, as presumably the box and HDD are tied together via serial numbers.
The server su.tv.talktalk.net still appears to be working fine, as mentioned in the above thread, but pcds.vlx.tv.talktalk.net (aka files.cdn.talktalk.net) does not, which is where the software update is/was stored.
I understand that TalkTalk no longer supports these boxes, but it is very poor form to not keep the software update servers online (these are owned by TalkTalk, not YouView!), especially because it breaks the recovery option in maintenance mode. Please can TalkTalk look seriously at restoring access to software updates? If not, please consider making the software file available to download so users can copy it to USB memory stick to use with recovery option in maintenance mode.
Just to conclude this thread, the issue with update servers has now been resolved. This means the the "Internet/USB Recovery" option in maintenance menu now works again. I have now been able to replace the failing HDD in one box and get the box working again with the latest software. I have also been able to fully update the software on the box that was stuck on an old update (last updated January 2020).
Replacement hard drives for the DN372T cost 9 from eBay - the same WD AV model - hardly expensive. There is nothing wrong with the rest of the hardware - it is a TalkTalk server issue. Seems silly to bin perfectly fine hardware, just because of a server issue. But, anyway, forget about broken hard drives for now - think more of the users who find themselves with out of date software, unable to update their box.
I have now confirmed the findings from the other thread, using Wireshark. Software updates are now broken for everyone because the pcds.vlx.tv.talktalk.net update server is not responding correctly. The other thread said back in July that the requests were resulting in a 404 not found HTTP error, but now the server is failing to respond at all. This causes the "Internet/USB Recovery" option in maintenance mode to hang forever at a certain point (when it tries/needs to download the dn372t-upgrade-Cds72.48.91Mc4Ps3.6.216Pc4726Api3.2.0Sta12.01.30.P.release file).
As the other thread says, software updates are initiated via =1234 and I have also found that internet recovery updates start with =1234 - the result of both is the same. It tells the box to download the above file, if that version is not already installed.
As to why TalkTalk didn't inform you that they were being withdrawn, another question is, why should they? As far as they are concerned this would have been a business decision and those who had boxes wouldn't have needed to know as they were working. Alternative boxes were offered to customers if they were eligible under existing contracts. From what you say, the contracts applicable to your boxes have now expired.
Good luck in getting this back working, and as said the box should overwrite the latest software, however old the current version on the box is (this was confirmed by YouView staff on their now closed forum when this question was raised).
I don't visit these forums as often as I once did, so did not see any announcements here - certainly nothing was mentioned in my TT account page, or emailed to me by TalkTalk (either separately or in the monthly billing notifications).
The first two were supplied by TalkTalk as part of my contract renewals. The third was supplied as a replacement by TalkTalk, in January 2020 (when I last updated it), after the front panel on the first box started misbehaving (I swapped the front panel PCB from the replacement into the box with the iffy front panel, fixing my original box). The fourth was purchased from eBay as faulty, for spare parts, but in fact was/is working 100% ok (HDD tested good too).
The HDD is definitely dying on the box I have an issue with - it is failing diagnostic SMART checks and is developing bad sectors (initial symptoms were recordings failing, getting stuck on waking up, etc). So, I know the HDD needs replacing - there is nothing else wrong. The HDD in the other 3 boxes test ok. Unfortunately, as I say, it is not possible to swap HDDs between boxes to troubleshoot things that way. The new HDD (exact same model number and size as the original) was unformatted to begin with, but the three boxes I have tried it with, will not install the software on it or format it. I have also tried partitioning it manually, to the exact same sizes as working drives.
Factory and software resets do not require a full software reload as these options do not wipe the software completely. The Internet/USB recovery option does. As mentioned in the other thread, it seems likely that recent (at least 2 years) of incremental updates are still available, but if you need the latest full base software (which I believe is from May 2020), then that file is no longer available from the update servers. The software is installed on the HDD, so if you have a blank new HDD, you need to use the "Internet/USB recovery" to download the software onto the HDD, before any more recent updates can be applied. Hindsight is a wonderful thing - I wish I had downloaded and kept a copy of _huawei/PVR2_DN372T/Huawei_DN372T_B48SP91_Release_20200512/P... to avoid the current situation.
From memory the drive should be unformatted when 8nstalled as the box takes care of this. Also the TalkTalk boxes are limited to 320gb, so if the drive you are using has a greater capacity, I don't think it will work.
Swapping out the HDD was always at the user's risk with no guarantee of the replacement working. Now that the boxes are no longer supported I am not surprised that attempts at installing the software are failing.
