Dell 5190 (NASHER / 17898-1) Full ROM with Clean ME

[Axel Manrique]

Hello, I'm repairing a bricked Dell 5190 (NASHER) with a CH341A programmer. A standard dump from another (working, modified) machine is not working. I suspect it's an Intel ME region conflict. Can anyone please share the MrChromebox "Full ROM" file for NASHER, but with a **Clean ME Region**? Thank you.

Hello Dani,

Thank you for your reply!

Here is the original BIOS dump from the bricked laptop:


Motherboard Model: 17898-1
Service Tag (S/T): 9SFK2P2
*Please note:* Since this is a refurbished unit, the Service Tag on the chassis might not be 100% accurate for this specific mainboard, as cases can sometimes be swapped for aesthetic reasons. However, the attached original BIOS dump should contain the correct internal identifiers.

Full Model Name: Dell Chromebook 5190 (NASHER)

Also, I have several dumps from other *identical and fully functional* Dell 5190 (NASHER / 17898-1) mainboards. These include:
- Dumps from machines already modified with MrChromebox's Full ROM.
- **Original factory dumps (with ChromeOS firmware) from untouched units.**

Let me know if you need anything else.

Thanks!
