Dear friends, I just bought a JTAG/RGH XBOX360 slim (yes I know it's 2018 ). I am playing around with it, changing the dashboard etc. All the games seem to be running fine as well. I took a backup of the console’s NAND using "Simple 360 NAND flasher 1.2" and when I loaded the "flashdmp.bin" file into J-Runner; it shows that my console has 6 bad blocks (please view the attached snapshot). Should I be worried ? Console is running fine otherwise.... Please help me!
A Jtag / RGH is still a very nice purchase in 2018, regardless of its age the 360 is still one of my all time favourite consoles. Bad blocks on a nand are normal, if the console is already hacked then these bad blocks have been remapped to good blocks which are reserved on the nand. If you ever flash and updated nand, dump a backup of your existing nand and use that as a base to build the new nand, flashing it with Xell (powering on the console with eject boots this) that way any bad blocks will be remapped and the console will work as normal. It's nothing to worry about either way though.
