I found out that the tv is using tbml10, so tbml8 should be the backup. The problem is that when I'm trying to mount them so I can check out the versions, tbml8 returns nothing, after waiting for a couple mins. And tbml10 returns failed to mount, device busy. Since I couldn't doublecheck the exact versions installed, I didn't dare proceed with the swap. Any idea why this is happening? Should also note that the TV is connected wirelessly to the lan, using the official dongle and the signal ain't that strong. Also, it's not a new set with 3000 installed only. It used to have 2000something before it got "upgraded".
Any help would be greatly appreciated.
I advice you to use ethernet cable for connection. Instead of mounting that partition at TV, please copy contents of that partition to your computer. (like mounting NFS/Samba directory by hand or copying to USB dongle)
So you can check partition on your computer. And you could look into it if it's empty or not...

Now, I want to roolback to 2006 firmware, but instructions on wiki for old firware is not very good (something to mount...). Can you please tell me step by step to roolback to older firmware, like it was written for roolback from 3001.1 to 3000.2?
I don't even thought if Telnet Enabler working with 3001.1 device. Revert backing is working via enabling alternative firmware link. Since you are already alternative firmware, you cannot revert it back to any earlier version with same technique.
You needed to update your current alternative firmware location. (3001.1 loaded) You can force to update those locations IF ONLY IF you have CI device. CI+ devices will enter bootloop!
You can look instructions for Force Revert Back wiki page (dangereous way section).
I advice you to use Boot External Firmware via USB device for experimentation. With it your are in the safe side and could recover your TV later if you bricked...
