Excellent guide...I was beginning to get discouraged...after 2 FAILS...FINALLY...SUCCESS
Thought this might be helpful to some, since quite a few seem to be having the same problem...
I started off with XBR/8955 on my xenon JTAG console. (DVD drive is spoofed w/ iXtreme..Hitachi047 spoofed to MS25-maybe contributed to my problems)
First, I upgraded to 9199 built from freeBOOT ToolBox Maker, but, I forget which version of the ToolBox...either v2, or v24r3, used pre-JTAG NAND as source - everything was working fine after this update.
Then, I used Jtag Tool 2.20 and used my original pre-JTAG NAND, flashed XBOX - FAIL
Then, I used this guide with my 9199 Freeboot image, flashed XBOX - FAIL
FINALLY, I used this guide, and took my XBR image to extract the KV, SMC, and smc_config - SUCCESS
My FAILs were like many others here...No video, no green ring, no error indicators what-so-ever, and Xell/Xellous was gone.
FIX: I had to re-solder my LPT cable, reflashed xellous (I had to go figure out how to build xellous...I started with JTAG back with Xell), and I put my updflash.bin (the 9199freeboot.bin image) onto a CD as a file, and re-flashed with xellous off CD...I could not find a USB drive that worked with Xellous.
I'll edit and add screen shots from 360 Flash Tool...I don't know what most of the numbers mean, but, looked quite odd to me.
