How to revert back to Firmware 1.01.00

I have seen postings that Sandisk has reverted back to firmware 1.01.00. However, whenever I use the firmware updater, it says I have the latest version 1.01.05. How can I get the 1.01.00 firmware version.

If your still under warranty may be call support.  Here’s a post in thread (on page 2) DO NOT DOWNLAD LAST FIRMWARE UPDATE!!! by PeteBlack message 40:

Problem solved !!!

Here are all the firmware revisions (I recommend 01.00.04 or 01.01.00):

Extract the mi4, font and ROM files using 7z unzip (you’ll find it on the net) and copy the extracted files into the root folder of your device in MSC mode and then disconnect it from USB. It will “upgrade” (or downgrade if you wish). If MSC mode is missing, put the player into Recovery mode by switching the HOLD on and hold down the record button for a few seconds.

Be sure to pay attention to the region code.
SansaC200 A 1_00_03.7z

A is America.
E is Europe.

F is Europe with FM

P is for Pacific
… Not really sure about the rest.

Once completed, the USB>MSC mode will be restored !!!
