I know, I've messed up... It's my fault. I've launched first TR-A03_SLIC.EXE, it gave me some some CRC errors. Then I've extracted the BIOS-A03.ROM only and I had the bad inspiration to flash it with amiflash64. Restart, and now the computer is dead. No beep, no HDD or CD activity, only the power LED and fans. I've recovered the original BIOS-A03.ROM, put it on several flash drives using several names, nothing. No activity on flash drive LED. Resetting the BIOS jumper works somehow (after releasing it the computer starts), but still nothing happens... My feeling is that the keyboard has no reaction at all. It's an USB keyboard, the system has no PS/2 connectors. Any idea would be highly appreciated...
Have you tried to insert the bootable USB stick (<2Gb, FAT32) in the various USB ports ? Usually works only one port.
No activity on any of the 8 USB ports... FAT16, FAT32, bootable, non-bootable, nothing. I've tried to find a kind of naming rule using hexedit, nothing. The "-writehdrfile" command don't work (as I've found on other posts). I've restored once an HP laptop, but definitely I've seen activity on USB Flash Drive, so after several tries I've found the right name for the BIOS and everything worked fine. Now I'm completely hopeless...
The BIOS recovery procedure for this model is so classified, that neither the authorized DELL repair centers don't have a clue... The M/B will be changed as still in warranty and the bricked one will be re-flashed at the main factory... Serg008, thanks for everything and keep doing the great work that we all need so much!
