SanDisk Sansa View

Hardware

pcb scans: very basic ones

PP-based, most possibly with a secondary nv61x0 chip for video etc.

Firmware

mi4 firmware (two images). Decryptable with a recent mi4code.

Disk layout and hidden partition

The player has a disk layout similar to the SansaE200FirmwarePartition, which has code in a second hidden partition.

UMS mode

You can initiate UMS mode by doing the following steps:

• Turn on the Sansa View and let it boot up.
• Switch the hold switch to the hold position.
• Hold down the left side of the scroll wheel for a couple seconds, and while still holding, plug the USB cable in.
• Keep holding until the player shows "Connected".

Another way to initiate UMS mode if your OS does not communicate to it via MTP is to just plug it in and wait a bit. The player will attempt to reset the MTP connection, and then when it realizes that is not helping, it will switch to UMS.

The output of lsusb -v will also be very useful.

I attached the `lsusb -v` output of both the Sansa View in MTP and UMS mode. -- BlakeJohnson - 18 Feb 2008
