Hi chabbu,
Lucky for you, you have a 3.x.x version firmware which the
s1fwx tool can extract and the
s1res tool can modify the firmware.
You can download the s1fwx tool here:
S1fwx 2.6 - Firmware extractor.
This is an older version, but should work fine on the 3.x.x version firmware.
The s1res tool here:
S1res 1.6 - Firmware changer.
This is the older, FREE version, but should work fine on the 3.x.x version firmware.
There are lots of themes submitted by members in our [Downlaods] --> [
Themes] section.
Hope that's helpful.
