Hi Ok I have a Falcon with 7371 FW , I just installed the Nand X to find out my CB version. So this guide is the most popular So far I have soldered in the Nand X wires and installed the USB nand drivers on my Windows 7 laptop Ok So I got this far , I have the Nandpro20d Folder on my desktop, how and on what do I type -r16 orig.bin ?? I opened the Nandpro20d folder in CMD , I typed --r16 orig.bin , the dos just says 'bad command or filename' I tried running the Nandpro application in the Nandpro20d folder , which just opens then immediately closes for whatever reason The guide is not clear enough for the average Joe public , I havent yet worked it out , spent several hours using other guides with other programs such as Collshrimp's Jtag tool I havent yet installed the Jtag , just the nand . Apparently I am supposed to check the CB version right ? Any help guys ?
