> I've been trying to upgrade a grandstream BT-101 phone, whatever I do,
> it doesn't seem to want to upgrade. I've pointed it at the
grandstream
> TFTP IP listed on the wiki, I've also tried pointing it at my own TFTP
> server (after putting all the firmware images downloaded from
> grandstream website into /tftpboot).
>
> Is there any specific trick I should know (eg, upgrade in some
sequance,> or hack my tftp server in some way, special files/etc..)
>
> Also, any comments on what the overall best firmware is for these
> handsets currently would be interesting...
