Q1. My Archos 45d Platinum is not detected by the tool. What should I do?

Reinstall SPD drivers, try a different USB port, or hold Volume Down while connecting.

Q2. Can I use this firmware on the Archos 45 Platinum or 45c Platinum?

No. This file is only for the 45d Platinum (SC7731). Flashing on other models will brick the device.

You need to use WriteIMEI Tool (for SPD) to restore your IMEI. Back it up beforehand if possible.
