I am trying to convert this sensor (Green PCB and White CBU module)
I had success doing so with similar sensor that is Blue PCB and White module.
The same method fails here as I get random errors reading or writing:
I am quite beginner to this kind of hacking so I am wondering whether there is something else to try out before going ahead desoldering the CBU module which in my case is almost guaranteed kill of the device?
AI: Could you provide the exact model and version of the TH01 sensor you are trying to flash?
CBU with AHT20
AI: What operating system and additional hardware or software are you using in your setup?
Linux and ltchiptool
