As most of you know some of the community was unable to downgrade to 1.5. This is because they got caught with the unlucky motherboard ta-082. if the 2.6 firmware can write to flash (2.6 to 1.50 downgrader) whats stoping a 2.6 based custom firmware? fanjita and ditlew announced that they were working on an in ram hack that would allow homebrew working from the xmb. But what is stoping from a patch to the 2.6 flash to run homebrew?
