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!

Hi,

It looks like your phone is running on customized firmware (29.71.19.5), what’s why the upgrade failed.
Please contact your reseller or provider and ask them to help you.

Hope this will help.


Thanks for your answer. Unfortunately, we haven't any way to contact with our provider Sad . So, do you know if there is any way to reset phone to any standard version?

Hi,

I can’t help you any further. Sorry about that.
Please find out who is the distributor of your country and ask them if they are willing to help or sent a mail directly to Yealink Support or submit a support ticket.

Hope this will help.

Thanks. I'll analize options.
