Dell latitude 7420 need clean me

Re: Dell latitude 7420 need clean me

Your backup is not good the compressed file is only 61.4 KB ,if you look at the other backups in this thread you will see that they are at least 11MB in size.

The filesize before being compressed might be 32MB but it is mostly all zeros, look at the code with a hex editor

.

The file size is 32mb but I get the 61kb any time I compress it.

Is there a way you can help me build without the backup file? Looks like the main file is corrupt and I already flash a backup file from here,the SSD is not showing.

Are you sure its corrupt or does the fault lie with your programmer and backup method. What model and software version is your programmer,have you desoldered the chip,are you using an adapter board.Have you soldered wires to the chip,are you using a pogo adapter .

I used a pogo adapter to back up,I guess that's where the problem came from, when I decided to write another file on it I kept getting the write error via pogo adapter,I then had to remove the chip from the board and use the adapter board.

Now I already write another file and there's no way I can get the original back up file again since the first one I used pogo adapter with is bad.

Is there a way you can help me build a new file without the backup because as it stand, there's no way I can get a good backup file again.

I will help in future if you learn how to use a hex editor and look at the code to make sure the backup is good.You don`t need to know what the code means just that theres some code there, you can compare backups from this thread with yours.The file size after zipping the file is a fairly good indicator as well.
Post your service tag and someone can check the laptop configuration at dell support and tell you which bios in this thread to try

If you have "Code 10" problem most probably you are using a dump from another machine, to solve that replace ME region in this dump with the ME from your original dump, or just clean the ME Firmware:

No, you look for a hardware problem.
