Thanks for posting those images, saved the links to them in case some other hapless 4dtv victim needs them My EMM is 4160, my "CK" says 3435 the sub mode is US my "TDT" is 1708.
Whatever all that means. I'm still a bit sketchy about "US" unidentified service working even after browsing through the posts. I'm sitting on T7 (wishing it would come on so im not in complete silence here)
The 4160 means your on the Comcast SAC. The 3435 means your running Decembers CK. Your TDT is fine for conversion. Motorola has fixed the glitches a few weeks back, I would redo the 4 Step to no brick on my site. It probably will work and then you can watch tv .
You actuator is probably frozen. If you get signal & quality on X4 forget it for the short term since forcing it may screw it up completely. Do the conversion again, since your on 4160 already you can probably skip step 3. If that don't work do all 4 and report back. Good Luck.
"US" unidentified service means just what it says. In short it cannot find the Service ID so nada, nothing.
