Yealink Forums

Hi everybody,

I have a new T58W with Camera. I crashed the yealink with a T57 .bin version.
I have White screen with "close application" messages and black screen, grey screen, so on...

I tried to reset to factory default by pressing the redial key.

But after I have a message 1. TFTP 2. USB

I put on a USB Key the T58W-150.86.0.5.rom file : I have "USB Failed" message
I put on a USB Key the T58W-150.86.0.50.rom file : I have "USB Failed" message
I put on a USB Key the config.bin of a another good T58W file : I have "USB Failed" message
I put on a USB Key the 805e0c861bb1-all.cfg of a another good T58W file : I have "USB Failed" message

All the time, I have the same "USB Failed" message.

Please help !!

Thank you in advance.
