It took a full 2-1/2 weeks after talking to Mits and convincing them my problem with trying to use a multistream CableCard was set-related and to finally receive the upgrade firmware. Why they make this so hard to get is beyond me. Nope, you can't download it! You have to call, give your model & serial # and then have a "known problem" that the latest firmware addresses before they will give it to you. They then verify the problem and call you back a week later to tell you they're sending the chip. Geeze....Just because you might want new firmware doesn't mean you'll get it. The latest version is 8.04 (most sets came with 8.00 in 2006 and 2007). If you want to get it, tell them you're trying to use a Scientific Atlanta multistream CableCard and you're getting an error message 161-050 on screen. (Release 8.04 fixes that problem). It probably addresses other things too, but I don't know what those bugs are. (maybe someone here knows and will tell us!!)
Even still it's going to take 2~3 weeks to get it. Mine arrived today, strapped to the belly of a mule (UPS Ground). What you receive is a 4-gig Compact Flash (CF) chip which contains only 18.9 megs of data. Why they used a 4-gig chip for less than 20 megs of data is beyond me.
Anyway, suspecting they might have a self-destruct routine in it, I copied the chip they sent me and burned the data onto a 256-meg CF chip of my own, then used my chip to perform the upgrade. Sure enough, at the end of the upgrade, the CF chip is wiped clean, ostensibly to prevent you from sharing the data with anyone else, God forbid, (unless you were wise enough to copy it first)
The upgrade process is a very specific procedure, but not difficult. You turn off the TV and unplug it
- which you must do. Then insert the CF chip in the reader on the front of the TV. Now plug the set back in but don't turn it on
. Just sit, wait and watch. Your green power LED will be flashing like mad then after a minute or so will finally stop. In another minute or so the TV will turn on all by itself and you'll see a message come on the screen a few seconds later informing you that the software upgrade has completed. Unplug the power cord, wait 10 seconds and plug it back in.
Finally turn the set off and wait for the green power LED to stop flashing, then remove the CF chip and pull the plug one final time (10 secs) then reconnect, Done. You may have to rescan any OTA channels or CableCard channels you had, but any "settings" are retained (thankfully).
Mits fully expects you to return the CF chip, as they send an envelope and UPS return tag in the package. I've heard of people getting billed for $36 for not returning the chip, so returning it as requested is probably in your best interest. Since they make the process easy and free, there's really no excuse for not returning it. There's no data on the chip anymore, it's been erased.
The upgrade solved my problem with the CableCard.
In addition to the upgrade firmware, the chip contains some potentially useful diag. screens (color bars, greyscale, vertical/horizontal alignment test patterns, etc) so copying first before use nets you these nifty files (16 of 'em in fact)
