One customer asked what SWFL lost means at the bottom of the screen. SWFL number is showing when Xhorse VVDI2 read key ok.
Here is the answer:
The “SWFL lost” prompt is normal after BDC is unlocked.
Do not worry about it.
If BDC has no communication due to improper voltage or other reasons.
Restore Flash with ESYS or ISTA.
Hope this could help!
