Change fimware from Enreach / Swyx to 3CX - f.ender - 09-20-2023 10:56 PM

Hello,

I have some t48s Phones and want to change the Firmware to 3CX Firmware.
But I only get the message:

Code:
Firmware update failed!
Unlicensed OEM
Neustart, bitte warten ...
I can change the Firmware from swyx to swyx (lower or higher) but not to 3CX or normal Yealink.

I have read that there is some "brake-off" Firmware to change the brand, but I don't find any or who I have to contact to get the Firmware.

Can someone help me? Thanks!

See some information from them about it here https://service.swyx.net/hc/en-gb/articles/360017746859-Yealink-T4xS-CP-Phones-Additional-Notes-on-installing-firmware

(Which phone model and which firmware version does it currently have?)

Hi,

thanks for your reply.
I have a Yealink T48s with the Firmware 66.85.133.10.

But your link helps me! I had to downgrade the Firmware to 66.84.133.12 and then create a license at the Yealink License Center. Then it was possible to Upgrade to the Firmware version 66.86.0.15.
