NAND Sweeper

This allows you to SWEEP or DUMP the NAND and SD card. These features are explained below.

The app comes in two versions (NTRJ and NTRJ-Secure). I don't know the specific difference between them, but NTRJ-Secure will not boot.

SWEEP

The SWEEP function allows you to set every byte in NAND or the SD as 00, FF, 55, AA, or incremental/decremental and random patterns. The location to start writing is set through the Input Transfer Sector.

DUMP

DUMP displays a hex dump of the NAND and SD. The Input Sector Address sets the location to start reading from, and dpad-up and dpad-down are used to scroll through the hex dump.
