RE: Firmware won't upgrade to handset
Hi nicvon,

You are quite right, but if your handset contain customized firmware, like the OP have, you can’t flash the handset with other firmware only than customized firmware from the same supplier.
e.g. if the handset runs 26.50.188.1 you can upgrade to 26.80.188.1 but not to 26.80.0.15

Hope this helps.

Kind regards,
Frank.
