Getting There
Precautions;
As with anything that writes or modifies the nand it is possible for a error to occur which may cause E79. This can be fixed by either using a LPT cable or USB-SPI flasher, you can even use Xellous to re-write your last working nand, but in most bad flash cases Xellous is not functional. You follow this tutorial at your own risk; I am not responsible for anything bad that may happen to your console. This is the way I have updated my own and other peoples JTAGs and you should be fine if all steps are followed correctly. Now with that out of the way, on with the tutorial .
