So i was trying to rgh my xbox 360 s corona 16 mb. I soldered the wires correctly. I plugged the power of the xbox and then plug j runner to pc. At first j runner was showing a lot of f and my xbox is turning on and off. I thought something is wrong so i unplugged the jrunner and the power. I plugged it again and it was doing the same thing. I unplugged it again and plugged it, now there is a red dot. I think i messed up my nand. J runner says version: 0x00000000 can not continue. Guys please help me.
