NAND programmers

A NAND programmer is the bridge between your computer and the Xbox 360's flash memory. Every method begins by reading that flash and ends by writing a modified version back, so a working programmer is the one piece of hardware no install can skip.

Common choices

xFlasher 360 dedicated A purpose-built programmer designed specifically for 360 NAND work, popular for its speed and convenience.
JR-Programmer classic A long-standing dedicated programmer that pairs naturally with J-Runner.
Raspberry Pi Pico / PicoFlasher budget An inexpensive microcontroller running PicoFlasher firmware, a low-cost route into NAND reading and writing.

What it does in the flow

Connect
Wire the programmer to the console's NAND and to your computer.
Read
Dump the existing flash so J-Runner can recover the CPU key.
Write
Flash the modified image back once it has been built.

Keep your dumps

Always save a clean copy of the original NAND before writing anything. If something goes wrong, that untouched dump is what lets you restore the console to where it started.

Any of these programmers works with J-Runner; pick the one that matches your budget and the consoles you plan to service.
