shout at your seller, it said upgradeable and it provided the firmware and it was naff, start to complain if no response put a claim in fr the money bac and the price is way too high for that player from ebay, try your best to to get them to refund as they are to blame here
like i just said to nexus it may be impossible to find a firmware that works bacuase so many of these are around even if they look alike does not mean it will work
we will try an see if there is anything but first i would try and get the money back as we can direct you to much better players for same or less
paypal and dispute is actually the easier option than searching for firmware
