Long story short: I got a broken Oracle Touch. Overall it's state is really good, but I've traced the following fault:

- One of the boiler valves were leaking, causing moisture buildup on the top cover.
- This moisture condensed on the on the triac board causing an arc from L to fan control pin
- That completely fried the STM32F429 on the main MCU board...

So while I'm perfectly able to replace the CPU with a new one I can't find the firmware anywhere.
This is really a long shot, as the FW contains all manufacturer secrets so either it would be unavailable or encrypted.

Anyway here I am asking: do any of you have access to the FW and could share the file?
