Stop using canned trash to do your JTAG. It's like eating food from a can. You don't know what's inside.
Download FBBUILD with the newest dashboard files and use that instead of "easy" or "piggy" tools lol.
I use FFBUILD like this:
1st: Make a txt file, paste this inside and save it. Rename to make13599.bat then paste it on the same folder where FBBBUILD is at...
fbBuild -v -c xenon -f 13599 -d s_data\ updflash.bin
2nd: make a folder called s_data
3rd: inside of the said folder put the following files:
cpukey.txt (inside paste the CPUKEY as text, no spaces or anything else before the key)
KV.BIN (YOUR DECRYPTED KV
, should MATCH
the CPU KEY on cpukey.txt)
SMC_CONFIG.BIN (YOUR SMC CONFIG settings. Stuff like mac address, DVD player region, operation temps and fan speed go here)
SMC.BIN (SMC FIRMWARE hacked for JTAG HACK. Should use the one that's proper for XENON in your case.)
Once all files are ready, double click the bat file you made and a cooked dump called "updflash.bin" will be ready for flashing at the main folder of fbbuild.
Honestly this is even easier than using bestpig's stuff as this never fails.
