Hello everyone,

I'm looking for help with a completely dead Dell Inspiron laptop after an interrupted firmware update. Laptop Information

• Brand: Dell
• Series: Inspiron 15 3000
• Reg Model: P112F
• Reg Type: P112F001
• Service Tag: 3M9S7K3
• Express Service Code: 7877035587
• Motherboard: GDM50 LA-L241P Rev. 1.0 (A00)
• Board Date: 2021-04-19

Any help would be greatly appreciated.

Thank you!

Hi, try flashing both of these files for your correct SKU (0AB0)
P.S: "puce 1" is indeed 8MB, but "puce 2" is actually 16MB, NOT 8MB
You only read 8MB of it (half the chip), which is why you're confused

You're Welcome! Make a new backup of "puce 2" and post it so we can see what can be done

I don’t understand why you’re asking me to make another backup of chip 2, since I already provided that backup initially in my archive. And anyway, I wouldn’t be able to make a backup of the original chip anymore, because in the meantime I flashed it with your file. I don’t understand.

Yes, I know. I said a new backup. I mean make a backup now, after you've already flashed the chip, so we can see what has changed in the BIOS

This is not adding up. Write back your original 8MB backup and see if it works
If not, try these 16MB BIOS files one by one, allowing enough time to boot after each flash

"puce 1" is 8MB, and your dump is exactly that size, so it should write without any issues

P.S: When writing to any chip, you need to follow this exact sequence: erase --> write --> verify the write

This laptop has been repaired by someone else. I don't know if the BIOS is different.

Try flashing only the 8MB chip. Test these files one by one, and give the laptop enough time to boot before trying the next one
Also, note whether any of the files make the 1,5 error disappear (You can discard outimage4 since that's what you already have anyway)

P.S: This might not be the final solution. I'm trying to establish a pattern to build the final files for you, so give feedback and don't forget the (1,5) note
