读取备份nand四遍

读完后用jrunner合成——creat xell-reload，然后write xell-reloaded。读写nand操作是插上主机电源，不开机状态下进行，严禁开机。然后拔下2148刷机板，断开主机电源，进行4148二极管焊接。

1N4148二极管很便宜，淘宝上几块钱一大包，运费贵过物品。穿上热缩管，防止短路。

焊接图，焊点大很好焊。

然后插上主机电源，接上视频线，插上网线，开机，几秒钟后出现xell画面。在j-runner上输入ip，直接get到cpu key

合成17559的nand，create xebuild image

用U盘去j-runner目录下将合成的固件updflash.bin拷入格式化成fat32格式的U盘根目录下，然后插入开机xell状态下的主机，等待读写……会有英文提示，不要着急关机，一定等写完……

与正版机开机时间一样，进去后看固件，已经是17559

现在能碰到还可以jtag破解的xbox360主机很少了，遇到了可别错过，练练手。这张图是单双65的jtag图，齐了。

补充一点,破解成功后最好把主板背面的R6T3电阻去掉

R6T3 is the label of a resistor on the mainboard of the Xbox 360, it supplies the necessary voltage for the Xenon (CPU) to burn the so-called eFuses. Burned eFuses prevent older firmwares (any older rev. than 4552) from running on your Xbox 360, thus eliminating the possibility to downgrade to an earlier version of the kernel. The Resistor itself is located in the field T-6. It is a 10k Ohm (10,000 Ohm) SMT resistor (Case 0402) functioning as part of a current limiting circuit.
