Hi, I just have the same problem...
I need to download fimware 3905.9-2-2ES1.
Anyboby have it?.. I couldn`t download from the links in this site.
Link provided in previous posts for 3905.9-2-2ES1 firmware is not working. but the good news is that issue is resolved in new firmware 3905.9-4-1-0 but I had to upload individual files from .zip extension one, the .cop.sgn did not work.
Thanks for all above for their posts it helped alot.
