dlldroid / clone_i1d3

This tool can read the data out of the iD3 and write it to disk, it can also take data on disk and write it back into the i1D3

Notes:

This work is shared AS IS. You use it at your own risk. It is possible, though unlikely that you could damage your probe if used. This work was inspired in part by the driver code from Argyll color management system

full credit is given to Argyll’s author for any code similarities. https://www.argyllcms.com/

Additional information was obtained by the use of the protocol analysis tool Wireshark https://www.wireshark.org/

Further information was obtained by extracting the firmware from i1d3 using PICKIT2 tools from Microchip and analysing it with Ghidra https://ghidra-sre.org/

As a note, no Windows dlls were analysed in order to create i1d3util. It was just not required!

The i1d3 has both internal and external eeproms. The internal eeprom contains the serial number, the external eeprom contains the unique device sensor calibration data and the “signature” that determines which flavour of i1d3 it is locked to (oem, retail, colormunki,C6 etc.)

The command i1d3util -? will give a help screen

The i1d3util tool has a number of command line options, both in lowercase and uppercase. Lowercase are read commands, uppercase are write commands. The i1d3util tool can read the data out of the id3 and write it to disk, it can also take data on disk and write it back into the i1d3. By doing this, you can backup and restore your probe. The i1d3util tool can access both internal and external eeprom data. It can also specifically access/change the serial number and signature data.

For example, if you have a retail probe and the signature data from an oem probe, you can load the oem signature into the retail probe. The probe will now operate as if it were a factory oem probe.

The –f option enables you to overwrite (without warning!!) a file on disk. The –w option enables ACTUAL writing to the i1d3 eeproms! The –v reads the firmware revision from the i1d3 hardware

Example command to load a oem probe signiture file into ANY i1d3 probe:

i1d3util -w -S oem1D3signature.bin

It is STRONGLY RECOMMENDED that you save you probes current internal eeprom data, external eeprom data, signature data and serial number before you start changing anything

Be VERY careful to write the correct data file to the correct section of the probe!!

It is possible to corrupt the internal eeprom. If this happens, the i1d3 reports back a different USB Vendor ID. The i1d3util will try and detect this and correct the problem.

Between each WRITE to the i1d3, it is important that you unplug and plug back in the probe to reset the Windows device driver.

Once a write operation has been performed, the i1d3 sometimes starts flashing its white LEDS. This is normal, and is part of it visual feedback system. Most application will either turn this off or allow you to turn it off/on

Have fun!

clone_i1d3's Issues

Help！My i1D3 (ViewSonic)

I modified the cpp code, add the cs-xri1 unlock code, then I backup internal external signature, I wrote the "retail_I1D3signature" to my i1D3, and it bricks, always give me "Error: Failed to unlock the i1d3" .
Can u give the unlock code, How can I rescue my i1D3? Thank u.
