USB FW: 3.15 boots....sort of

Thanks to everyone who hooked me up, here is whats going on.
1)I can boot the 3.15 FW using JaiCrabs tool
2) there are display problems
3) System freezes when selecting System Settings

Im getting the HDD dump soon, this may prove useful. My first idea was to replace all the %flash crap in the XML files with /dev_flash, so that the USB FW wont look at the nand when getting settings and files. So I will try this tomorrow and post the results. If someone gets to it first let me know the result.
