mackk1e Posted April 23, 2013 Share Posted April 23, 2013 I recently recovered from a bad bios update, I had to erase the bios and to reprogram it using a Parallel Port SPI Flash Programmer, now there are certain functions that doesn't work, Cpu fan doesn't spin // 4 Go of ram not fully recognized // Ctrl+Alt+Del shuts down my laptop instead of rebooting it.So now I need someone to dump the whole bios chip for me using pure DOS using FPT and I'll flash it to my laptop.I attached the necesseray files (Given by Prema) to do it , at DOS type STEP1 (it may reboot your pc ) after still in DOS type STEP2 and you will have a file named backup.bin you can upload here.CLEVO_full_backup.zip Quote Link to comment Share on other sites More sharing options...

mackk1e Posted June 19, 2013 Author Share Posted June 19, 2013 Hi prema! I found a complete backup of the Spi flash that I did earlier (before I erased the SPI completely) and I was thinking if you can help me reconstrut a bios image merging the backup I did and a new bios image sent from the vendor. I just don't know what offsets should I keep from the backup and what offset should I copy from the vendor bios file to merge the two and have a working bios image.

Guest Posted June 19, 2013 Share Posted June 19, 2013 First write the complete backup to the chip, then only update to the newer BIOS, otherwise it'll get messed up. Quote Link to comment Share on other sites More sharing options...
mackk1e Posted June 20, 2013 Author Share Posted June 20, 2013 Sorry I didn't explain it very well, the backup I have is the one from the bricked bios image which means that this backup have missing or damaged code if I flash this backup to the bios chip I'll have the same problem as before a black screen and nothing else, this same backup contains some code that normal bios updates don't have as they only update a part of the bios and I want to merge these two files using a Hex editor . to be clearer it's has been done here here are the files compressed in winzip (these unpack with no problem) W870CU.zip corruptbios.zip Quote Link to comment Share on other sites More sharing options...
Guest Posted June 20, 2013 Share Posted June 20, 2013 I can't unpack the archives because they report as corrupt, too.... Quote Link to comment Share on other sites More sharing options...
