which file did you flash after renaming it?

Didn't replace it , just add some thermal compound between CPU and thermal pad. And I also stick a small fan on the shield which I removed on my old PC.
Unhopefully I already ordered the programmer (EZP2013 USB2.0) because I was under impression a lot of cheaper programmer may not have the proper software or support. So far I ordered the same stuff (including the test clip) and your pictures confirm what the IC to flash is. I guess I have no option else removing the shield to access the IC. By the way, after flashing it with success, what did you do about the shield and the thermal pad? Did you replace it? I'm curious about.
Now I'm worried about something: activation key. So far I had "Just for a moment..." when dealing with Windows 10. I guess this code is activated only when you enter WIndows 10 successfully and asks for it, isn't it?
I seriously don't like the RMA option because it will take money and time to get it back working (or not) as it should have been from the start. That activation key - to have it put with those important items like BIOS firmware and BIOS parameter in the same basket (IC) is totally amateurish and dangerous in design term. Now I don't wonder why it is easy to brick it.
The chance I can retrieve my activation key may appear slim but as long as I can try to read the IC, I want to try to rescue it. So, LP team, could you provide as soon as possible the details where to find it in the IC so I can extract it?
The flash job will cover all the code in Bios chip including the KEY part .Because the bios file is for generally use ,I think the KEY part in this file must be all FF. So, if you flash it , you will loss your KEY like forever .Unless you backup it from your bios chip ( the program software can read the chip info. ) or in the system. - You Reply: After that, program the bios

Plug into the power and wait like 10s ~ 1min, you can see the red LED will turn off as normal if you succeed. Then hold the start button, tada, you LP is reborn.
And it will take some time to start at first time almost few minutes. You may see it loop and loop
If you see the LED blinks or still turns on, try it again.
Good luck to everyone who wants to try!attachments:

Select the manufacturer of the chip and select the right model (GIGADEVICE GD25Q64 , remember?)
20181008 Updated: Possible to be w25q64(winbond) for different batch!

10.jpg (152.12 KiB) Viewed 47721 times Now, just plug your programmer in to a USB port on your PC and use the software of the bios programmer.
First you need to download the right bios file from the official site. It is very important to match the right image with your system architecture.
In this case I used the 4GB 64GB version

You can either desolder the bios IC or clamp it in to the programmer, or you can use a solderless clamp similar to the one below like me (Which I'm bought in Taobao too .Which I’m highly recommend!! It’s so simple to use!!!) .6.jpg (85.36 KiB) Viewed 47863 times

This is the model of my bios programmer/flash:CH341A 4.jpg (51.69 KiB) Viewed 47863 times Actually, you can use any bios programmer as long as it can write 8MB GD25Q64 chip

20181116 Suggested by raidensnake. Here're details:
I would suggest using ASProgrammer 1.4.0 instead as it's more stable in terms of flashing and it also supports the CH341A hardware and drivers.

The other one has either issues where the needed chip names aren't listed or the flash process doesn't work properly.attachments:
