The Canon EOS 300D (marketed as the Canon Digital Rebel in the USA) was one the first sub-$1000 digital SLRs.
There are several hacked firmwares available, that extend functionality and add stability:
- Undutchables 0.2.3
For reference, this page also has Canon's original v1.1.1 firmware (MD5: 327354c4697db3d936cc724258e7517f).
Canon has detailed instructions for flashing firmwares on the EOS300D. The instructions, in short:
Format a CompactFlash memory card.
- Copy the firmware file (*.fir) to the root of the memory card.
- Insert the memory card into the camera, and turn it on. The camera should prompt to install the firmware upgrade.
- Format the memory card again before attempting use.
