RE: T27G Firmware Update Failed
(11-12-2019 05:58 PM)Infonetx Wrote:  We recently updated to 3cx Version 16. I was working in updating our Yealink T27Gs and T27Ps firmware versions. The T27Ps went fine. But the T27Gs fail. This includes through their management console and manually through the web GUI of the T27G. Was using 3cx provided Firmware, T27G-69.84.0.95, but also tried Yealinks T27G-69.84.0.90.

Currently on:
Version
Firmware Version 69.83.0.55
Hardware Version 69.0.0.0.0.0.0

Hi,

Please follow next steps and try again:

- Reset the phone(s) to Factory default and do not re-provisioning.
- Download the T27G-69.84.0.90.rom file directly from the Yealink site (http://support.yealink.com/documentFront...entId=138)
- Manually update the phone(s) with the downloaded file
- Reset to Factory default and check on the new firmware version
- Re-provisioning the phone

Hope this will help.

Kind regards,
Frank.
