This project contains a collection of firmware and data for Casio Ex-Word electronic dictionaries. Dumped using this script: https://github.com/dictscript/dictscript

• nor-and-nand/: Stores NOR and NAND firmware images for different dictionary models.
  • <model>/nor/: Stores NOR images.
    • 1fxxxcleaned-true: Indicates that the extracted NOR data has been cleaned.
    • trimmed-true: Indicates that trailing blank FF data has been trimmed from the file.
    • unlocked-true: Indicates that the Test Menu password has been unlocked.
  • <model>/nand/: Stores NAND images.
    • builded-nand-from-extracted-files: NAND image built from extracted files.
    • extracted-nand-files-from-device: NAND files extracted from the device.
• nor-and-nand-extracted/: Stores the contents extracted from resource files in the NOR and NAND of the dictionary.
• nor-and-nand-updater/: Stores firmware updaters.
  • CY-series-dataplus5-updater/UPDADN3.BIN: Updater for DP5 series.
  • L-series-dataplus4-updater/UPDADN2.BIN: Updater for DP4 series.
• addons-on-dictionary/: Stores additional dictionaries.
• addons-on-dictionary-extracted/: Stores content extracted from resource files in additional dictionaries.

Note: Files larger than 100MB are compressed and split (*.xz.001, *.xz.002...). Please merge and decompress them to get the original files.

The flashing process is performed in the dictionary's engineering mode (Test Menu).

1. Enter Test Menu:

   1. Ensure the dictionary is powered off.
   2. Press and hold Exit + Page Up + Power for about five seconds until the screen turns on and displays a "Model" window.
   3. Release the keys, then press the Right key twice, and then press the Enter key to enter the menu.

2. Prepare TF Card: Select the corresponding option in the Test Menu to format a TF card (2GB recommended).

3. Prepare Firmware Files:

   • NOR Firmware: Select a suitable NOR image from the nor-and-nand/<model>/nor/ directory. The unlocked-true version is recommended. Rename it (e.g., CY123OSB.BIN) and copy it to the root of the TF card.
   • NAND Firmware (Optional): Build with nand_build.py or select a NAND image from nor-and-nand/<model>/nand/ (e.g., CY123D0B.bin) and copy it to the root of the TF card.
   • Updater Program: Depending on your dictionary model, select UPDADN2.BIN or UPDADN3.BIN from the nor-and-nand-updater/ directory and copy it to the root of the TF card (UPDADN2.BIN may be the firmware updater for the series whose file names begin with LY, and UPDADN3.BIN may be for newer models whose file names begin with CY).

4. Start Flashing:

   • Insert the TF card containing the above files into the dictionary.
   • Select OS UPDATE or the corresponding option in the Test Menu to start the flashing process.

Note: Flashing carries risks. Be sure to back up your data.
