RE: T27G Firmware Update Failed
I appreciate the reply.

I went through the steps as you laid them out.
- Factory default, by holding okay and selecting yes.
- Downloaded, and attempted to install the T27G-69.84.0.90.rom from Yealink. Gave me a 'Firmware Update Failed! Rebooting, please wait...'
-I went ahead and factory defaulted and checked the firmware version, just in case, still the same version.
- Following the most recent factory default, I tried some of the newer, but not newest versions of firmware from Yealink as well, but all failed. Each accompanied by a factory default prior to. (I tried Yealink 69.84.0.80, 69.84.0.10, as well as the 69.84.0.95 for the T27G from 3CX)
