I have Yealink CP960 which used to work well until I decide to upgrade the firmware (old firmware 73.80.0.50). I have download the latest firmware CP960-73.84.0.25.rom while the upgrade process is taking place I think the Power went off accidentally! (Poe injector cable get lose).

now can't boots up, and it hangs at Initializing screen.
I'm unable to do anything at all. How to reach recovery mode on cp960!? Any ideas Please.

Finally Good News!

Yealink reply to me previous ticket and sent me link contain Recovery mode process on CP960 (plus other model, seems updated version!) the most important they sent me new files CP960.bin and CP960.rfs which were the main reason for the recovery mode to work this time!

it's working now .

the process :

1- prepare formatted usb flash (FAT32)
2-copy the needed files (CP960.bin and CP960.rfs and the CP960.rom) (I have used what yealink tech. sent me) to the flash drive.
3-plug the USB flash drive next to the micro usb
4-switch on the CP960
5-press Home (the circle) when you see "initializing" keep press until you see another screen which will do the recovery automatically ! cant be easier than this .

Thats it .

BIG THANKS TO MongoTEL_Support , and Thank you Yealink Technical Support team.
