Title: Uninstall Sansa Fuze+ Bootloader
Post by: c84574 on March 10, 2012, 06:03:17 PM
Hi,everyone!  ;D

The Rockbox (v1.2.13) >Uninstallation>Remove the bootloader keeps showing

Quote
Rockbox Utility can not uninstall the bootloader on this target. Try a normal firmware update to remove the bootloader.

What I did was.
 - Format fuze+
 - Download the firmware (http://mp3support.sandisk.com/firmware/fuzeplus/fuzeplus02.37.01.zip)
 - Extract .sb file into fuze+ root directory
 - Restart

Then it shows

Boot version: 1.0
arg=CAFEBABE addr=40000000
Loading firmware
File not found

Please help..

You have to actually boot into the Sandisk firmware, rockbox won't know what to do with the sandisk firmware update file.

How can I boot into the Sandisk firmware? Is this the hold the volume button and the power button?

EDIT1:
I manage to boot into fuze+ (by holding volume and power button) but the problem is, it's not updating the original firmware.

EDIT2:
I finally get it to work!

What I did.. (2nd time)
 - turn off fuze+
 - hold the volume down button, plug into computer (force MSC mode)
 - Download the firmware
 - Extract .sb file into fuze+ root directory
 - turn off fuze+
 - "Loading firmware File not found" shows up
 - press volume down button (to boot sansa firmware)
 - wait for the update to finish

Thanks to saratoga for the help! Greatly appreciate it!  :'(

hi was a lovely piece and helpful but i spent hours unsuccessfully doing it again and again until i realized that the firmware you manually install has to be the same or later version as your current one or it won't won't won't work!!!!!!!!
