Negative response code 0x71 reports that the data-transfer operation was halted. The important next evidence is what happened immediately before the interruption.

What to check next

Keep the full programming log and record any supply, connection or tool warning. Follow the approved recovery instruction for the identified controller. Do not treat a suspended transfer as confirmation that a particular memory chip has failed.

Useful information for an enquiry

Provide the stage reached, module identity and whether power or communication changed.

Repeated retries without resolving the interruption can complicate recovery. Preserve the original data and use the supported process.
