Hi have you verified the image with an md5 checker just to make sure it did not get corrupted on the download , if theres enough space and the tftp kicks off ok thats the only thing i could think of might be stopping it , or have seen before where disabling firewall locally allows it through but a default timer may turn it back on that could block it as well half way through depending how long it takes

Is your tftp-server able to serve big files? If unsure, use the newest version of TFTP32.
