Hard reset a T20P and erase config
Good day.

I have a problem with a T20P phone. It is auto provisioned by my upstream provider, and we were testing before we rolled out a hosted solution.

The phone was operational when the testing was completed. An upgrade was then done on the phone to the latest version of broadsoft software, 9.71.193.6, but at the same time the test account was deleted.

Now I need to reset the phone, but nothing works, web interface, Pressing the OK button or uploading a new rom via TFTP, as the provider had set a unique password that was lost when the account was deleted.

So in short I do not have the admin password for either the web gui or the OK reset, and the TFTP upload retains the current config.

Any ideas on another way to recover the phone???

Thanks in advance

Can you ask your upstream provider for help? They can help you with recovery mode.

I think you should ask your distributor for help and run RMA or not.
