Hi,

What you can try is this:

Create a plain text file (e.g. features.cfg) and add next parameters:
#!version:1.0.0.1
features.power_saving.power_led_flash.on_time = 0
features.power_saving.power_led_flash.off_time = 100

Log in your phone, go to Settings > Configuration > Import CFG Configuration File then Select and Import the previous created cfg file.
If everything went well, the 2 parameters have been imported and your issue should be solved.

There is also a Provisioning Guide available, called "Yealink SIP IP Phones Auto Provisioning Guide V1.0.pdf"
