I haven’t grab my GP2X from a long time ago, and browsing some web pages I found out there have released several firmware updates (mine was 2.1.1) so I decided to upgrade it. Here you are how to do it:

Firmware 4.0.0 update

First of all you have to upgrade to firmware 4.0.0, otherwise your GP2X will end up as a brick:

1. Download the firmware 4.0.0.
2. Extract its content in the root of the SD.
3. Insert the SD into the GP2X.
4. Plug the AC cable to the GP2X.
5. Turn the GP2X on and accept the upgrade.

Firmware 4.1.0 update

Now you can go on with the the latest firmware update::

1. Download the  firmware 4.1.0.
2. Extract its content in the root of the SD (you must overwrite firmware 4.0.0′s files).
3. Insert the SD into the GP2X.
4. Plug the AC cable to the GP2X.
5. Turn the GP2X on and accept the upgrade.

It doesn’t work

If you get stuck in the “NOW PATCHING” screen, try copying the files to another SD card.

Warning:

• ALWAYS upgrade using the AC cable, and NEVER using the batteries.
• The upgrade is safe, but keep in mind you are doing it at your own risk.
