I know thereÂ’s a way to load custom firmware, with Mac cloning into them. I know a few use a jtag from an old xbox360. I have the general gist of it. But trying to find how to load custom firmware there use to be a site called sbhacker that had full guides but thatÂ’s dead and gone. If anyone can point into the right direction IÂ’ll do the research. IÂ’ve been googling for the past few months and hit a dead end.
