How to flash a fake 750ti (550ti)

[Queasy Tiger]

Okay, so here is some backstory.
While browsing eBay for some cheap graphics cards, I wondered upon an auction for a fake 750ti.

It was clearly a fake card, as even the seller stated in the description that the card was fake, and was in fact a GTX 550ti.

My curiosity was peaked, and after thinking for a few minutes, I put in my max bid at £15, and forgot about it.
A few days later, I got an email from eBay saying that I had won the auction for £5.60.
Pleased with my bargain, I sent the payment, and waited for my purchase to arrive.

Now, I must stress that I knew about these cards at the time, and about flashing the bios to make them appear correct, but hadn't read up on the subject.
I was under the impression that you could flash the bios of these cards through software, but I now know this isn't true.

 

I would very much like to get this card working as a 550ti but nothing I have read online makes sense to me.
This video from PhilsComputerLab explains the process, and provides links to some of the hardware needed (Although these links are now either dead or not being sold anymore), but I cannot figure out how he actually does it. The software for the programmer he uses seems like utter gibberish to me, and how would I get hold of the bios in the first place to flash onto it?
 

Now excuse my ignorance, I still haven't done much reading up on the matter, but I suppose if somebody has the knowledge and can give me some insight on here, then it saves me scrolling through web pages wondering if what I am viewing is the right thing.

I need to know some simple things.

What hardware do I need?

What software do I need for the programmer, and how do I use it?

What bios do I need?

Is there anything else I am missing?

 

If someone could give me a hand, it would be greatly appreciated.
Thanks in advance!

If you have any questions please ask.

you can get the bios from techpowerup's vga bios collection page

 

as for bios flasher, it's usually connected to a computer through USB while the clamp goes onto the card's bios chip.

From the screencap on the Philscomputerlab video though, I don't understand how I would get the bios onto the chip

That's why you need a bios flasher, search term "bios chip programmer". They come with software for PCs to control them through USB.

Sorry if I'm just being dumb.

I just don't understand this interface:

Do these flashing devices come with some form of documentation to tell me how to go about using it?

I would guess that you might need to do soldering as the bios chip would almost certainly need to be removed to flash it properly. If the card is inserted into a computer the chip needs programming to know what it is fundamentally and erasing everything would make it a blank. Thus I would assume ( I could be wrong) then when these fake cards are being purchased they have the chips removed and flashed with the 'fake' gpu flash to try and scam people. This also stops easily reflashing the boards to the proper gpu. If you watch youtube videos about people buying these fake cards to test them I have not seen one where they could get the original bios back on the GPU. If someone finds one please let me know as that would be a nice knowledge video. 

 

If you check bios flash devices like https://www.amazon.ca/Programmer-CH341A-Burner-EEPROM-Writer/dp/B01D4CXYJE you would need to know how to remove the chip from the board and solder it onto the writer and then back onto the GPU.

I know that they don't have to desolder them, because they tend to use a clip like this:

That makes contact with the pins on the chip.

I dont have hands on experience, but I think you just select the downloaded bios file by pressing the "open" button and then flash it in with" flash "button on the top bar.
