I offer my collection of firmwares for handsfree Parrot CK 3100 LCD. Because  Parrot Software Update Tool, does not support return to the previous version,  so I began to save the previous versions of firmwares and here is it for download. Versions that are not in this list I do not have, don't write me about them. But if you have a version that is not in this list, I'll be glad when you send it to me. To expand file, use 7-zip (for free), archives have up to 600 KB. Any errors or other version of firmwares please send parrot@kerpof.net. Do not write me if your handsfree does not operate, I am not technical support! 

We assume no responsibility for any damage to the handsfree while flashing those files! Everything you do on your own risk!
