Im a mexican boy with the same problem. Here are the instructions step by step. I follow the instructions and have my iriver in optims conditions. JE Sorry for my badly english. Seguro Funciona jejeje

I will answer my own problem. (i intially sent this problem hoping to get an answer)if anyone has had the above problem, i have the answer. First,i called the 360-567-3599, their is an automated service that ask you what type of h10 device you own, DO NOT pick the device type,(example: if you have h10 5/6 gbs press number 3, etc.)Later, you will hear about estore questions, keep listening, when you get to the end, you will hear, "all other questions, press(i'm not sure what number, but push that number) a live representative will help you. Let him know that you tried everything and it still does not work, they will have you send it to them. i was soooooo pleased with my device when i received it. all my music is gone but that's ok, but have it backed on my windows media player so i just downloaded it again. P.S. make sure when you mail it, that you get insurance, return receipt, the works, to ensure that you receive it back in one piece. I think i will return it to them in the future if it stops working again.

Try this and let me know if it works http://www.iriveramerica.com/support/hd/H10_upgrade.aspx

I have the same problem. I also tried to call that same number a few times and stayed on for about 45 minutes each time and there was no answer. Please let me know if you fixed your problem and how. Thanks!
