hi again to everyone.
i found the airlive's firmware, and i replaced the first few lines of bin files with hex editor (the hex thing written here
http://www.macsat.com/macsat/component/option,com_openwiki/Itemid,66/id,flashing_with_a_new_firmware_image/ )
when i select the new firmware and click upgrade the lights goes crazy and 10 second later there is a "unallowable firmware" error. the device continues to works old firmware.
i searched the forum but nothing. :-(
is there any lock or something to not use hacked/different firmwares on the device...
Thanks.
