400plus is a free firmware enhancement software which offers additional functionality and capabilities for your Canon 400D/XTi camera, in both a non-destructive and non-permanent way. It works by loading into your camera's memory automatically upon boot-up to enhance the native camera firmware; but it is not a permanent firmware upgrade, and can easily be removed.
Fixes:
- "Quick exposure" now works continuously while you are holding the DOWN button down.
- "Fixed exposure" now works while you are holding the SET button down; there is no need to press once to enable the feature and once again to disable it.
- In the "Long exposure calculator", you can now change the Ev, and the calculator will compensate by changing the exposure time; you no longer need to play with the exposure time to achieve the desired Ev.
- When pressing the DP button to enter 400plus' menu, the original menu does not flash in the display.
- When the "Better DISP button" is active, press the DISP button once then cycle through the brightness levels using the UP, DOWN, LEFT, and RIGHT buttons, then press SET to leave the feature; pressing DISP twice will switch the display off.
- Actions attached to TRASH and JUMP buttons are now called shortcuts, and work a bit differen. In general, you must hold down the JUMP or TRASH button, then use UP, DOWN, LEFT, and RIGTH to use the feature. There is also some info on the display about the active shortcut.
Before you begin:
In order to install 400plus you are definitively going to need a CF card reader; it is simply not possible to install 400plus through a USB cord attached to your camera.
Install 400plus into card
- Download the latest official release, extract it, and copy the AUTOEXEC.BIN file to the root folder of the CF card.
- Create a new 400PLUS folder on the card's root.
- If you want support for additional (non-English) languages, and copy the LANGUAGES.INI file to the 400PLUS folder.
- Insert the CF card back into the camera... and you are done!
About Digital Camera Firmware:
Updating to a newer firmware version than the one already installed on your camera can improve the device’s overall performance and stability, resolve various issues, and add support for newly developed features or enhance existing ones.
On the other hand, downgrading the camera’s firmware can recover its functionality in the unlikely event the currently installed version is faulty or the device’s performance dropped after an upgrade. However, bear in mind that applying an earlier build might not always be possible.
It is recommended that changing the camera’s firmware be performed when the new release resolves an issue that your device has been encountering, or adds a new feature (or enhances an existing one) that could prove useful for you.
This process isn’t intended to be destructive, but still, it’s best to save all your personal data and configurations before applying a different firmware. Moreover, make sure that the battery is fully charged and don’t use the camera’s buttons while the installation is in progress.
When it comes to the update method, usually, you must copy the firmware file onto a compatible memory card, insert it into the camera, and browse from the menu to the device’s update section.
However, each device has various ways to enter the update mode and particular steps that should be taken for a successful upgrade, therefore make sure you read the product’s installation guide.
That being said, if you consider that this firmware improves your device in any way, then hit the download button and get the desired version; if not, check with our website as often as possible so that you don’t miss the update that will boost your camera’s performance.
