T42S firmware upgrade
Hello everybody,

I'm trying to recover the usage of my T42S, I tried to upgrade since it wouldn't accept the Yealink BT40 Bluetooth dongle I purchased with it.

I saw that more recent firmware version could help and tried to upgrade to latest version via web interface. The phone could not find any network anymore.

I'm trying to install version 66.81.0.110 of the firmware (which I will rename in T42S.rom), but I also need the files T42S.bin and T42S.rfs files. Where can I find those two files that are missing ?

Thanks for all in advance.

Eric.
