The 6.3-megapixel EOS 300D/Digital Rebel is very similar to the 10D which has more advanced features. Basically, they are using the same CMOS sensor and DIGIC microprocessor; some of the features have been disabled on 300D. Firmware is a software program or set of instructions programmed on a hardware device, it can be erased and rewritten, stores on the ROM. Sometimes manufacturers release firmware updates to fix bugs or make the devices work more efficiently. It’s also possible to modify the firmware to reveal the disabled features.
Warnning! Camera with hacked firmware will not be covered by manufactory warranty. But you can always load the original Canon firmware if necessary.
The most popular firmware hack was done by Ravil and Wasia, it’s called Wasia hack, provides the following additional features:
Enter Flash Exposure Compensation using SET button
SET button function when shooting
Shutter release w/o CF card
Flash sync speed in Av mode
RAW+JPEG rec. Sets the quality of embedded JPEG
Mirror Lock up
Selects the autofocus mode: AIfocusAF, ONEShot
ISO 3200

The new UnDutchables firmware upgrade is built on the Wasia Russian firmware. It allows some of the more advanced functions to be available in basic shooting modes.
New features added in unDutchables 0.2.3:
Full menu's in basic mode including RAW quality
Full Info screen in basic mode
AF-mode select moved to right key
Left button press turns AF off, release turns AF on again. Effectively this puts the lens in manual mode while the left button is pressed.
Pressing it when in AI-Servo mode will therefore release the shutter.
You loose AF during button press though. This means that AI servo does not support predictive focusing.

Watchouts (According to the documentation):
Camera may lock up if you attempt to change the language, maybe possible to change the language but must be done on the original Canon 300D 1.1.1 firmware.
Some features may not work correctly if you are using another language - use English as a workaround.
If you upgrade and some of the things don't seem to work properly, set the settings in the Custom
Function back to the original values (see below) and install the original 1.1.1 firmware, then upgrade to
the new firmware.
If MLU does not work, ensure that the camera is in single drive mode.
When using a flash with the MLU enabled, the flash will fire when the mirror lifts and again with the
shutter opens.
Menu items for the MLU timeout will show a few arrows – ignore the arrows.
The quick erase may have altered something with the code used for monitoring the battery, and the low battery icon may appear earlier than expected.
Numbering of the custom functions are incorrect but the functions themselves are correct.
Picture quality can now be modified safely via the menu in all modes.
If the AF drive is set to AI-Servo the AF confirmation Light and Beep are turned off (as done in the 10D)
but now it is turned off for all modes. Please change to AI-Focus or One-Shot if AF confirmation Light and
Beep is desired.
AI Servo with the left button release does not support predictive focusing.
All metering related adjustments do not work in basic zones. These include AEB, EC, FEC, ISO, focus
point select. AEB can be set in the menu but will not work.
Reverting back to the original version:
Reset all the Custom Function values to the original 300D settings. Note, you cannot use the Reset
option in the menu, it does not affect these values. Below is a list of default binary values from left to right (the bottom numbers in the CF menu): 0,0,0,0,0,1,0,11,0,0,0,0,0,0,0,0,0
