This purchase is for ONE 4gb Nand Extension QSB 

These are a quick solder board meant to make it easier to solder to the small 4gb nand points on Xbox 360 Corona consoles. 

They are meant to be left installed in the console permanently - removing them is likely to damage the console. 

Designed by ShawMerlin in association with Xtralife Mods and Geek Island Gaming

Purchase includes:

-1qty 4gb Nand Extension QSB - PICOFLASHER VERSION

NOTE:  These differ from the regular 4gb extension QSB in that they only extend the pads required by the PicoFlasher and nothing else! 

If you are trying to use any other reader than the PicoFlasher then buy the OTHER 4gb extension QSB. 

Quick suggestions 

Use Kynar/Wrapping wire:  http://amzn.to/2ljV7Bg 

Use Modshop's 4gb reading tool instead of Jrunner.  It seems to be less sensitive and succeeds sometimes when Jrunner fails. You can download it here:  https://weekendmodder.com/4gbSDTool.zip
