I spent 5 hours reading and applying all the different suggestions on this boards and it just doesn't work. It doesn't make any sense that everytime I want to use my ATV2 I need to do a tethered boot, specially because my computer is far away from the TV, so I need to do all kinds of antics to make it happen. Then, it takes like 10 tries just to jailbreak, boot, and get the maintenance menu to appear (which I cannot get it to appear anymore). So here is my suggestion: "Before you sale a product, make sure it works!!!" This is not opensource, people are paying for this thing and it just doesn't work properly.
Definitely, I am not upset (I'm not gonna go poor for $20 bucks) but the lack of attention from the company to this issue (I bought it back in december and still no fix) makes me weary of ever doing business with with you again. I don't know what you guys think out there, but this is how I feel.
Respect your customers.
