Cannot Factory Reset Yealink T20P, Tried 3 Methods
Hi there,

We have a Yealink T20P that we are having issues with that we would like to factory reset as we don't know the admin password.

- We have tried holding the OK button down to reset, when it asks for confirmation to reset we press OK and it shows the admin username, we press OK again and it says password invalid.

- We have tried upgrading the firmware using a TFTP server which has gone successfully but we still cannot login to the unit after it has finished rebooting. A new/latest ROM file was transferred during the TFTP process.

- It goes without saying that we can't get in through the web console either to reset this way.

Do you guys have any suggestions please?
All the best,

Matthew
