Ok, so I downloaded the HyperWRT2.1 and tried to upload it but I would get the error "Upgrade are failed! (GJ Linksys with grammar). I've also tried Alchemy 1.0 and I would get the same error. Can someone help me please? Thanks in advance! P.S. Oh yea, I have the 4.20.7 firmware from linksys. I heard there are problems with it, that's why I'm upgrading.
