Hi There,
we Upgrade all our Yealink T4XX Phones to latest Version XX.83.0.55. - There is a Problem with the OpenVPN Client in die Version. We know its not Supportet.... but i need to Upgrade to a Fix Version that Yealink Provide me. - Or i want to be Downgrade to Version V82. In this 2x Versionen openvpn will work.
I have a Big problem... iám not able to Upgrade or Downgrade die Firmware. - I Tryed with Upgrade via Phone Webinterface, Without Luck. - I Factory Reset the Phone try then Upgrading... no success.. - I Tryed with a Customer Template and put firmware to config file... still not Upgrading... - Now i god Recover Files from Yealink... also without Luck... :/
I tryed this now with 4 Differenz Phones. ( T41P T41S T42G and a T46G.... ) have anyone from you a idear how i can install the Upgrade?
Best Regards,
Marcel
