hi, try this...

hi, try this...

Thank you for your reply. However, my flash memory is 32 MB, while your file is only 16 MB. Are these just the files extracted from the Dell package? I don’t quite understand. The binary file contains data beyond 16 MB. Are you sure it will work ? Is it sufficient to have only the System BIOS information? Also, how can I create a complete binary image from the .rcv or .exe file provided by Dell?

Best regards,

hi, there
very strange oem files are 16mb.. I replaced the compressed filed with a new one from dell. Try this one but its still 16mb... I just flashed the same laptop here and it worked fine.
Is the file you posted the dumped one from the actual chip??

Hello,
Yes oem file are 16MB but full dump is 32MB I think there are not only bios on the memory.
It is a XPS 13 7390 (no touch screen, no 2 in 1) and not a latitude.

In this topic other pepole have 32MB binary and they can be openned with UEFITool NE


But my corrupted file I have some issue



If someone has a full 32 MB dump of the Dell XPS 13 7390, I might be able to fix my laptop. I have already tried using the files XPS 7390 32m.bin and W25Q256FV@WSON8 8X6_20230608_144945 Unlocked.bin, but the laptop remains completely off with no power LED.

With my corrupted binary, the power LED turns white and the keyboard backlight comes on for about 2–3 seconds before shutting down.

My computer is functional (before); I just want to unlock it. Before reflashing, I dumped the BIOS several times and compared the files to ensure they matched. I then erased and attempted to reflash, but it still doesn’t work. I suspect there’s an issue with my dump because the file cannot be opened with UEFITool, which strongly suggests the dump is corrupted.

I have a Dell XPS 13 7390 (non–2-in-1 model). The BIOS currently shows version 1.4, which seems to belong to the XPS 13 7390 2-in-1 model. However, for my system, the latest correct BIOS version should be 1.29.

Can someone help me replace the current BIOS with version 1.29 instead of 1.4?


Thank you.

Thank you it seems better to have a specific topic for this specific model.

I downgrade my bios to V1.29 with bios updater and USB key but its changes nothing my nvme is not detected. Do you have any Idea ? The fix to repair my corrupted binary maybe is not the right due to wrong model ?

Thank you for help

Hello,

I Think the issue is due to the very old ME region.

Thank you for you help.

Your backup at post 1 has two 16MB bios images, one after the other, that`s why there are two flash descriptors.

Try this bios.

[quarka35]

Try this bios.

It is works.
Memory is not only BIOS we need to keep configuration etc. NVME was not configured correctly, if I adapt configuration of default one It works too.

Thank you, for your help.
Best regards.
