Have you tried:

Thunderbolt Firmware Update 1.2: Keeps reappearing and Thunderbolt ports and Target Display Mode may not work - Apple Su…

Did yo do this:

This occurs when a self-powered Thunderbolt device (other than a directly-connected Thunderbolt display) is connected to a Thunderbolt port while installing the update.

To resolve this issue:

1. Shutdown your computer.
2. Disconnect all Thunderbolt devices.
3. Wait 10 seconds.
4. If you are using a Mac mini with a Thunderbolt display, reconnect the Thunderbolt display directly to your computer via the Thunderbolt port. Do not connect other Thunderbolt devices at this time.
5. Restart your computer.
6. If the Thunderbolt Firmware Update 1.2 is offered, download and install it and restart your computer when asked. If the Thunderbolt Update is not offered, the update has installed correctly.
7. Reconnect all Thunderbolt devices.

I have done this, but it does not resolve and continues to emerge update.

I took all the cables, and installed the update everything went right, put in the next boot, again comes the update request, it appears that this blocked the Thunderbolt port as it does not appear in the system information.

When I use the miniDisplayPort adapter for HDMI, the monitor works however is asking the update again.

This occurred only after Yosemite, before there was this constant update request

I do not know what to do.

The Apple 27" Thunderbolt display

only has a Thunderbolt video connection(it has USB for the USB ports on the monitor). The Apple display does not have an HDMI input. Thus it appears that yo do not have an Apple Thunderbolt display and thus the update is not applicable.
