Can I upload firmware 6.71.0.165 in Yealink SIP-T26P with firmware 6.70.14.3?

14.3 is a custom firmware from a vendor if I recal. There may be protection on the phone to prevent this.
Hopefully Yealink Support will chime in on this for you.

PS: as craigreilly said, 6.70.14.3 is a custom firmware. You can ask your distributor for the custom latest firmware. Their firmwares have protection.
