what you mean you rebooted after a minute?Believe it or not, I'm installing the update myself right now!
I think you need to have waited longer. When that error appeared for my spoof, the same error appeared but after a minute i rebooted and it worked. I'm 90% sure that the error code means that it is working.
I recommend you use the data deleter webtool and try installing again.
thanks this one worked very well
