SOLVED - F940BT "No Software Installed"


Recommended Posts

Hi Everyone

 

Trying to find a solution to my firmware update nightmare...

 

During the update to the latest FW thought everything had gone to plan, but now comes up with no software installed.

 

Had a quick read of this forum, and unfortunately I do not have a backup and I think/guess the HU needs a software rebuild.

 

Is there any way to fix this myself?

 

Thanking you all in anticipation.

I do not warrant this procedure working for everyone but I now have a working HU.

 

Used the SuperTestMode on a freshly full formatted microSD card.

Also on the card was the 4.6000 update downloaded from Pioneer and extracted.

 

From the SuperTestMode

 

1) I formatted the USER and NDATA partitions using the Drive Maintenance options.

2) Program Forced Write the update for all the options/components.

 

Quick note - without formatting the partitions the forced write failed each time.

 

Finally updated to the latest maps from the EU 2013 post on here.

 

Hope this helps someone
