Hi Jeff,

This is Jay from Yealink Technical Support Team. Greetings~

In this case, could you please let us know the MAC info of your phones first?
We need to check whether these phones have been bound to another RPS server which is used for redirection and provisioning.
If so, these devices need to be released, or it will download and apply the configurations from the RPS server automatically once you finished the factory reset.

In addition, the recovery files are only used for solving initializing stuck issue.
So, there is a way below you can try to reset the default password "admin".
0. Make sure that your phones and your PC are under the same network.
1. Set up an HTTP Server (maybe you can try hfs.exe) on your PC and upload the configuration file (120487.cfg attached) to this local server.
2. Set up a "Zero Touch" DSSKEY on your phone:
- Menu => Features => DSSKEY => Select one "Line Key" => Set the Type as "Key Event" => Set the Key Type as "Zero Touch"
3. Press the "Zero Touch" on the idle screen, and follow the guide.
4. Fill in the URL of cfg file, then press "OK" to apply. The phone will reboot after the configuration has been updated.
5. Now, you can reset your phone to factory setting by long press "OK" button.

Btw, as for firmware, I suggest you upgrade to the latest version. Please kindly check the link below to download it.

Thank you in advance.

Regards,
Jay
