That's what I did, but it resulted in brickingI'm not sure that this will solve the problem but it sounds similar to a problem that I have experienced. If you want to upgrade the firmware you need to go sequentially through them. First you have to have firmware 2.0.0 working. The subsequent firmware doesn't contain all the info needed to complete the full update / correct file problems you will notice the difference in file size. Then you can try Firmware 2.1.0 and 2.1.1 sequentially. I hope this helps.
