It's very easy to downgrade, install the older version and update the firmware...

Just execute the recovery procedure and upgrade to whatever version you want.

RE: Downgrade icom firmware
^^ put the restore version on an old usb and use the restore/recovery procedure.
Then upgrade to the version required. Follow the steps 1. Disconnect the ICOM network cable 2. Disconnect the ICOM OBD II jack of the vehicle, 3. Copy the file "icom_restore.bin" on the USB stick 4: Connect the USB stick to ICOM These next steps must be performed within a maximum of 5 seconds, otherwise the update process will not work. 5: Press and hold down the reset button 6: insert the ODB lead. 7. release reset button and then press the ICOM reset button 3 times and release: the LED will now flash and the icom will start to load the firmware from the USB. |
