WD40PURX Module 02 Checksum error. No access to data

[gameboybin]

Hi everyone. Need your help with this case. The drive has bad Head 04 before and wont let Module 02 Write back to upload LDR. After swapping new heads. The drive readies, full access to SA and can read and write to SA normally. However have the Module 02 checksum error. And wont let me access to user Sector

I have tried uploading LDR + Module 2 from different donors. Still have no access to data. Module 2 still has Checksum error

Thanks for the help!
