One customer gave feedback that his Key Tool Max Pro won’t update firmware. He tried with different network options and 5G phone hotspot but all failed and it gave “error=20_58”. Another Key Tool Max updated firmware without problems.
Here Xhorsevvdi tech answers:
1)Clear cache or Restore factory settings
2)Update firmware again
3)If it still fails, send it back to factory
Hope this could help!
