I don't even.
Do you know what the phrase "grasping at straws" means? Why is it so unbelievable for you that this is a feature of Gateway when there are so many other, more impressive features included already?
Once you've downgraded, the hard/risky part is over. Upgrading firmware is easy.
yeah, well just do it and report it - that would be useful.
Lots of people want as much info on the stability and reliability of this AMAZING downgrade feature - it's a pretty big deal. (I applaud Gateway for achieving it)
An upgrade from a downgraded 4.5 sysnand to (for example) 6.0 sysnand with a genuine cartridge is one more test that some people might appreciate
