First off I am no noob, dont mistake this for arrogance ive done hundreds of xbox's, I am considered a noob because this is the very first question\post ive had to ask since the beginning of the scene, so in your response please answer keeping in mind that i know what im doing but I just had an accident from lack of sleep and this is the one problem i could not fix. So..... Anybody else have this problem? Ive looked everywhere and cannot find a post answering this question.....I recently updated a RGH falcon and a JTAG falcon, problem being i flashed the RGH with the new xell 991 using 360_Multi_Builder_v0_80 with updated xell.bin 991, everything was fine then i went and updated the JTAG forgetting to change the xell binary (xell.bin) from xell-gggggg.bin to xell-1f.bin. Went and flashed it turned on the JTAG and got no power and 3 rrod error code 0021 i think or 0031. So in short i flashed the wrong xell image to the jtag falcon. Strange thing is when i flash any nand image i have earlier then 13699 the console works but if i try to update it goes dead again. Tried rebuilding the image many different ways and no luck so far. Anybody have any idea as to what is going on behind the scenes here?? Did i blow or short something by turning it on with the rgh xell binary installed? Does flashing the nand with no bad blocks actually rewrite the entire nand? Also tried every possible method of flashing the nand with same result.
