The first time you run the acm-backup-and-install.sh (or the e2m-backup-and-install.sh)script to backup all the nand partitions to your USB.

1. Insert a FAT32 formatted USB drive on the ACM or E2M P2 port
2. Run acm-backup-and-install.sh on your computer (or e2m-backup-and-install.sh on the E2M)
3. The script will finish and the ACM/E2M will start dumping the NAND to your USB into a backup folder.

After then nand is dumped you should see the following partitions on your USB:
