I changed the battery, the HDD to a SSD and the RAM from 2GB to 6GB (or 8, can't remember). When I try CMD + R it doesn't go into OS recovery. When going into diagnostics (holding D when booting) and start the hardware test it gives me a error code: ‘4SNS/1/40000000:TB3T-128.000’.
When Googling this error I find that this is a system sensor for the battery temperature that is not working. Did I buy a broken battery? Please help!
