This solution is share on DK forum by the member.

1.) FVDI V2015 or higher with softdog versions:

If the pc cannot detecting any fvdi’s then the LPC1788 processor was erased ( the Quickloader v6.3 will erase the LPC processor ).

always erasing are the following two address: 0x00000000-0x00047FFF or 0x00000000-0x0007FFFF

(click to enlarge)
After the FVDI died because there are no has a BOOT sector and the some firmware rows.

2.) if you cannot bought any FVDI’s from FLY Company, then the pc will go to internet then always erasing all FVDI LPC processors by FLY server !!!!!

3.) I solved all algorithms to fvdi firmware encrypting/decrypting and now i looking the 8bytes key to v2015 version.
