Can anyone confirm that they have successfully upgraded the firmware of a Logik T825 to version 13.0 via RS232?

In order to do this you would have used file t825_nohdmi_noci_nobrowser_nolpm_novhf_vD0_serial_logik.bin from Futaura's Vestel site. This is a modified (for serial update) version of the firmware that was broadcast as GordianT825UK018 via OAD.

The reason that I ask is that I have finally got around to trying to upgrade my Logik from its original 10.2 firmware. The new firmware file transfers OK using Xmodem 1K as per the instructions, the serial window reports "WAIT" (again as per instructions) but the new firmware is not accepted. The PVR simply reboots with the original 10.2 firmware.

If nobody can confirm that they have successfully upgraded a Logik in this way then a followup question (to Futaura?) would be: Do we know for definite that, out of all the various OADs broadcast, GordianT825UK018 is the one for a Logik? As I recall, the Logik PVRs were never specifically identified on the DTG website (and GordianT825UK018 and GordianT825UK003 were said to be for "Goodmans GHD 8020 v13.0").

AFAIK, GordianT825UK003 is for Alba brands (i.e. Goodmans). IIRC, the DTG did list the Logik models at some point at the same time as the Goodmans. Logik owners received the OAD while GordianT825UK003 and GordianT825UK018 were being broadcast. So I assumed GordianT825UK018 was for the Logik - I don't know for definite, but am 99% certain. However, it doesn't really matter - any Vestel box will in theory accept a download from other branded files too. Except...

Various users have tried upgrading via RS232 on the Logik models, and all have had the same result as you. After what looks like a successful upload, the box reboots and point blank refuses to apply the update and is stuck on 10.2. I asked somebody to try flashing the original unmodified OAD file too and that didn't work either. Maybe there is some extra trick involved in getting serial updates to work on the Logik boxes, but unfortunately I'm not aware of anything .

I don't recall the DTG site specifically mentioning Logik for that download. I cut and pasted the model description text for each of the downloads into a text file so I'm not totally relying on memory here.

But, the thread you link to (which I had forgotten) confirms that one of those firmware images was for the Logik and it does get upgraded by a broadcast firmware image. Reading about the stuttering with version 13.0 makes me think that I might be better off with the original 10.2 version. Notwithstanding that, I've just had another go at upgrading the firmware, this time trying the t825_nohdmi_noci_nobrowser_nolpm_novhf_vD0_serial_goodmans.bin firmware (i.e. the other image broadcast on 26th July). The result was the same: no upgrade.

So, my conclusion from all of this is that the Logik T825s cannot be upgraded over serial using any of the currently available firmware images. Looks like I'm stuck with 10.2 unless they repeat the broadcast and my PVR happens to catch it.

Now, back to my other project which is to do something with the files that I've now saved from the hard disk after the software crashed and then only gave me the option to reformat the disk. I now have reformatted the disk so the PVR is working again but only after I had copied all the files to my PC. I have some year-old recordings there that I'd still like to watch!

My memory is apparently failing me on this as I found a comment from me at http://pvrbugs.futaura.co.uk/view.php?id=180. Just trying to figure out exactly how I knew the OAD was for the Logik boxes too - either somebody told me after their box updated (although I can find no trace on e-mail, DS or AVForums), or it was listed on the DTG site at some point before the OAD started broadcasting. All I can find is a bunch of messages similar to the one in the above link on the evening of 26th July. I guess it doesn't really matter where I got the info from, but it's doing my head in a bit - obviously, I didn't just make it up.

It is strange that the box won't update via RS232, seeing as all the others (older and newer models) can be. Perhaps Currys/Dixons specifically requested this feature be disabled, or maybe it is just a bug.

The first post in this thread (the one you linked to) appears to confirm that a Logik is updated by a broadcast V13.0 firmware.


Seems unlikely to me to be a disabled feature. More likely either a bug or that there is something about the firmware image that is "not quite right" (e.g. a bad checksum) that prevents it being accepted via serial.

Apparently new, version 13.3. Just noticed it so I thought I'd highlight it even though it probably won't update the Logik.

It is probably safe to assume there will be OADs for all T825 models over the following weeks. The Sharp models were the first to get the OAD for 13.0, so I'm guessing the broadcast order will be similar this time around too. And before anybody asks, no I don't know exactly what the changes are since 13.0 in 13.3, but there are some new DSO related tweaks in there. I knew of the new OAD, but this is a bit earlier than I expected.

Yikes, I'd better wire up my Wharfedale Damn thing works fine for a while after a very long rest, then starts seizing up

Well spotted. Just downloaded it. As before, it consists of two firmware images:

GordianT825UK010 and GordianT825UK011

For the record, the DTG site has this to say about the download:
Date: Wed 12-01-2011 10am to Fri 14-01-2011 9am
Company: Sharp
Models: T825
Version: v13.3

"Gordian" sounds a bit ominous, as if Vestel software wasn't Gordian enough already

My Digihome DTR160 running V2.7 didn't pick up the Sharp V13.3 update...

Sorry this is a bit of a hijack, but to pclare, if anyone ever works out how to get them to accept software over RS232, do you have copies of the original 10.2 for the Logik LPVR168?

I'm not enjoying 13.0 at all, it stutters now and I want the Gemstar info stuff back.

I tried installing the 'generic' 10.2 from the futaura site with the same luck as you, but don't know if that would be the same as the factory installed one anyway.

I think futaura mentioned there is some identification in the first section of the .bin files that identified logik ones from others. Could that have something to do with them not accepting firmware intended for others?

I don't think so, no. It's mainly there for deciding which OAD the box should download. For updates via serial, you can upload any software version, essentially changing the "brand" of the box (which will affect which OAD it downloads in the future). Unfortunately, there is something different and unique in the Logik software that is preventing normal updates via serial - many users have tried, all with the same result .
