Lightbulb Yealink T28P Firmware Upgrade Fails
Hi,

I'm breaking my head over this issue for a few days now.

I'm trying to upgrade 10 Yealink T28P phones via the web interface, I downloaded the newest firmware and tried to update. It constantly skips the update of the devices and stays on the same firmware. I also tried putting them in recovery mode and pushing the firmware with TFTP. That also fails with the following error: Update fail, please reboot (12).

I have different firmware versions on my yealink devices:

Firmware Version 2.70.13.9
Hardware Version 1.0.0.39

AND

Firmware Version 2.61.13.22
Hardware Version 1.0.0.39

Cany somebody hint me to the right direction? Smile
