RE: Hard reset a T20P and erase config
Hi. I just stumbled for the same problem. A Yealink T20 with unknown admin password. Pressing OK will just show me the IP address, it does not reset. Can i get some help? Thank you.

RE: Hard reset a T20P and erase config
Hi there,

I have a similar problem with a T20 Sad

The "regular" reset to factory settings (vulgo "OK" for 10s) won't work and I really need to have this phone configured.

Could you pls share the information or send me a PM with it?

Thank you so much!

g.d.

I am facing the same issue but with a T48P, default username & password no longer work. Would you be able to PM the instructions.

Thank you,

Marc
