Unable to Update Phone Firmware since upgrading to v18

[doestreicher]

Hello,
yesterday we realized, that pushing fw upgrades to the phones via 3cx is no more working for us
We are using several Yealink T57W phones
I've attached a screenshot of the log-file.
Is anyone having similiar problems?
Thanks
Lukas

Hi Lukas,

Please read the following thread, pay specific attention to the replies by the official Yealink representative:

https://www.3cx.com/community/threads/bricked-yealink-t54ws-with-96-86-0-20-firmware.82455/

It's not a V18 problem, it's a Yealink problem and you will find the solution provided there by Yealink.

I will lock this thread so we can keep the conversation in the main discussion I linked above.

Please feel free to comment there if you want
