V1 radiator thermostat issue and replacement

vizone

Hi all. I have a V1 setup with 24 radiator valves. One seems to be bricked. It won't ever boot fully and start the calibration process.

First question... does anyone know how to overcome this? I've tried disconnecting for several days. I've ensured it is close to the bridge, I've tried reset. Firmware is 54.20.

Second question, if it is fully broken, I would like to replace but it seems v2, v3, v3+ is not backward compatible with V1. Is my only option to try and get a second hand v1 from ebay?

Thanks
