Just FYI, Rooting a Tablet and changing the "firmware" are two very different things and the terms are not interchangeable. Firmwares are also very device specific, you can only install a ROM on the tablet it was built for.
Please provide more information: what rom you want, etc., we can see if we can help

This is actually a good thing. Meaning it stopped you from installing a ROM which is not compatible with your tablet.
Otherwise, you may have already bricked your tablet.
Please see my comment in the other thread for the rest of your questions.

Please use the thead you have started instead of PM for this...i just read your post ......but i tryed so many roms ....always the same error..some people told me its cuz i have to root the tablet first....i was trying too many methods too with no luck ....
No, flashing ROM have nothing to do with rooting.
You do NOT need to root in order to flash.
They are likely talking about something else which is locked bootloader or recovery which prevents you from flashing anything other than manufacturer provided ROM.
Installing a new ROM will NOT give you magic speed.
However, your tablet seems to be based on Samsung S5PV210 (ARM Cortex A8) 1.0GHz. In theory, it should have good performance and if its performance is terrible, that can only mean bad firmware implementation which is not surprising.
We have seen Nvidia Tegra 2 based tablet made by some Chinese factory which runs horribly slow.....
My best suggestion for you is to ask the company that sold you the tablet to provide the latest firmware to flash on it.

Sorry, I don't. I only know about products that I sell or use myself. I don't sell or have your tablet.
