MSI GP62MVR 7RF Leopard Pro Bios

[jegerjon]

Hey guys

Hope someone can help me with a new bios or maybe fix the original bios for MSI GP62MVR 7RF Leopard Pro.

Bios was updated through windows but something went wront and it ended up with a black screen. It reacts to the power button, keyboard backlight comes on and fan is spinning.

Board number is MS-16JB1

Have tried E16JBIMS.31A from MSI website (https://www.msi.com/Laptop/GP62MVR-7...o/support#bios)

As well as an older bios E16JBIMS.30C I found on the internet. Both with same result. Can’t find anything else out there.

Hope to get it sorted before Friday.

Original/corrupted dump is attached.

Thanks in advance.

Thank you for your reply @SMDFlea

Yes I am positive. Can confirm it's GP62MVR 7RF with board MS-16JB1

Have attached pictures of the information I have available.

Which programmer do you use and which software? Are you reading/writing the chip with a clip/clamp or de-solder it? Do you verify the chip after flashing the file?

I am using the TL866 II Plus with Xgpro software and selected MX25L6473F as the chip, same exact markings on the bios chip.

I solder the bios chip directly to a SOP8 sub-board.

To my understanding Xgpro verrifies as part of the programming, but just did it manually after programming for the sake of this reply, it came back good and unfortunately still the same issue.

So you recon the bios file from the website should be good to go, for testing purposes at least, and should be able to be programmed directly to the chip without further action? In that case it seems like I am out of options.

Thank you for your time and suggestions, I appreciate it.

Yes, the BIOS from the official website should works fine if the issue was related to BIOS.
Here's the official BIOS, I know that you tested it before, but you can try again and see.
Also I can assume that the chip itself got defective or you have moved a tiny component around the BIOS chip by accident. So if the file doesn't work, you can try replace the chip and take a close look to the BIOS chip area under the Microscope (if you have one).

Thank you for your kind suggestions. I am (kind of) new to laptop repairs but have been microsoldering for 10+ years so am confident with the tools we use. Everything looks perfect under the microscope, this should 99,9% be a bios related issue, it happened when the customer tried to flash bios, it went about 1/3 and ended in this state.

Now, it was mentioned by SMDFlea that the model number from the front doesn't match the board number. I just spoke with the customer and the computer was bought second hand. Is there any possibility that the board could have been placed in another housing? Is that a thing?

In case that could potentially happen, do any of you guys have list of models born with the MS-16JB1 board? If so I'll just go nuts and try all the different BIOS' until something works.

I can see this Model Number "GP62MVR 7RF" in your dump file (DMI area and NVRAM section), so I guess your Model Number is correct.

Whatever, this official BIOS is for "GP62MVR 6RF", you can try it.
