Read full flash in current state of your ecu in boot mode.
Extract data area from addr $10000 to $1FFFF (OTP area) as separate file.
Get VR file created from SGO file (in attach) and insert extracted part inside in overwrite mode with any hex editor.
This will be full dump suitable to write with boot tool.
