| 10 | mkamsboot <firmware file> <boot file> <output file> |
| 11 | |
| 12 | <firmware file> is an original Sansa firmware file obtained from the Sansa |
| 13 | forums for example : http://forums.sandisk.com/sansa/?category.id=devices |
| 14 | |
| 15 | <boot file> is the code you want to execute (a rockbox bootloader), previously |
| 16 | scrambled with tools/scramble utility. |
| 17 | |
| 18 | <output file> is the resulting firmware file which you'll have to copy on your |
| 19 | Sansa player. See "Firmware filenames". |

| 48 | Dual-Boot |
| 49 | --------- |
| 50 | |
| 51 | The purpose of this program is to provide dual-boot between the original |
| 52 | firmware and the new (rockbox) firmware. |
| 53 | |
| 54 | By default the player will boot into the new firmware. |
| 55 | |
| 56 | To boot into the Original Firmware, you need to press the Left key. |
| 57 | ***Note : on the c200v2 you need to press the Right key. |
| 58 | |
| 59 | The player will boot into the Original Firmware as well if it is powered up by |
| 60 | inserting an usb cable. |
| 61 | ***Note : on the m200v4 powering up by usb will cause booting into the new |
| 62 | firmware |
