RE: cannot recovery phone
Hi Klaus!
Thank you for your answer... I try to explain better what really happened...
I've downloaded the latest firmware from the yealink's support site...
Through the web interface I've started an upgrade operation..
on the phone's it was appears a message "upgrade in progress... do no power off!!"
The phone was powered through the poe...
Due to fault of the poe's switch the phone was poweroff...
Now the phone keep on rebooting...
So I've started the recovery procedure....
I've powered off the phone... I've pressed the speaker button and power on the phone unti the recovery's menu' was appears...
I've changed all the settings in order to let the phone conneted to my computer and dowload through tftp the firmware...
I've renamed the firmware in t28.rom and I've started the tftp server on my computer..
On the tftp log viewer I saw the phone instead of requesting t28.rom file it was asked to getdifferent file: as I wrote you before it requested to get 3 files: ram_zimage.bin; fs.img; yealink.img...
This is the first time I see this..For all other phone in the past I did reflash through the recovery tftp menu, everytime they have requested the right file I was expected.... for istance the T22p asked to get the file t22.rom; the t26p asked to get the file t26.rom....
This is very strange...
I supposed the firmware of this file was very old and in the past the recovery menu instead requested one only file called like the phone model, it was istructed to asked for these 3 files...
Sorry I forgot to tell you for flashing the phone i used a cross cable .....
Please help me..
The phone is unusable...
