-Lift pin 101 and 122
-solder a cable to pin 100, pin 101 and one to 3,3V
-use a 2-way switch which either connects 101 to 3,3V or to 100
-put the switch into the position so that it connects 100 to 101
-power drive
-start Dosflash, it will recognise the SPI with Status x72
-if you read it out now, it will just give you a .bin full of FFFFFFFF, but thats OK, this is how we tricked the Flash Controller to think the SPI is empty
-put the switch in the other position (so that 101 is connected to 3,3V)
-now read the flash

断开101/122两脚与3.3V的连接
---101脚和1.8V(100脚)连接是一种状态
---101脚与3.3V连接是一种状态
在这两处状态的切换中读取新光驱的固件

风枪+手术刀除胶这块需要熟手! 生手就莫搞了! 不一定要断开焊接, 用手术刀划开PCB线路也是可以的
