Reply to Ean, is firmware flashing reversible?

I've looked around the community s but can't find the answer. Is Firmware 1.2 available? Some people simply want the firmware to go from 1.1 to 1.2.

Also, can someone revert to 1.2 firmware (I'm not talking about the special startup procedure) permanently? Say in a 6 months or a year, I want to sell my vci-100 and want to sell it as close to "OEM stock" as possible, can I flash it back to 1.2 after having done the 1.3?

Any help from anyone would be appreciated, (esp. Ean)
