just a note to everyone here...DO NOT USE THE SMC EXTRACTED FROM YOUR ORIGINAL DUMP !
fbBuild uses the SMC you give it VERBATIM, it does NOT patch it to do the jtag hack (alternate points or not, i use the original points)!
so, for best results, extract your SMC from 9199 freeBoot updflash.bin or similar, if you only have your original nand, use bestpig or any other way to make it and extract the SMC from that !
USING SMC FROM ORIGINAL NAND DUMP WILL RESULT IN E79 ERROR ON EVERY BOOT !
I had to use usbjtag to reflash because of this, do not be burned !
