T42G - Impossible to upgrade firmware
Hi all,

I have tried to update my T42G firmware and I can't. My steps:
- Download firmware from http://support.yealink.com/documentFront...umentId=11

- Access to phone web page Settings - Upgrade and put the updated firmware and Upgrade

All looks like normal (i can see updating firmware on phone display) but after reboot firmware doesn't upgrade. Have anyone any idea?

I have checked with some firmwares with the same result.

Model: Yealink T42G
Versión Firmware:29.71.19.5
Versión hardware:29.1.0.0.0.0.0

Thanks!
