Hi there
Last night I flashed my Rx 560 4gb card with a modded bios . Unfortunately the rom was not ok and I bricked my gpu . I have done almost everything (using another gpu to boot ,different mbs, hp usb dos ,...) without a success. My last chance and hope is to use a 1 and 8 pins connection of the bios chip on the card.

Please help to find out which one is the bios chip first and which pins are 1 and 8 so that I connect them correctly.
here is the photos of my card:

Thanks

did you try from DOS? You are going to need to do bootable dos usb(rufus), download Atiflash and a working bios.rom
It is also necesary you have another gpu in your system, it can be integrated gpu or just a discrete.

Thanks for your help
I have 2 different motherboards both have igpu . According to the instructions I have to go to mb bios to set igpu as the primary card. When I make the change in the bios and connect the bricked gpu to another slot , the system doesn't boot up and the screen is black but when I remove the bricked card everything goes back to normal

Whenever and in whatever way I connect the bricked gpu ( done it to 3 different motherboards), the display is  black and it never boots up . (tried dos bios flash at youtube  https://www.youtube.com/watch?v=mTqNP-N38BY)

 ??? ???
Any ideas guys?

Given the fact that my gpu model is different , I want to make sure which pin is which in order to connect them correctly. Unfortunately bios chips are not the same and for each gpu there is a unique way. Some pins 1 and 8 , somes pins 1 and 5 , ...

hmm, wierd.  
When you switch to igpu, you also connect monitor to igpu.  Check if you have any other setting in bios to force igpu, or maybe moving bricked gpu toother pci-e slot could do a trick.

it sould be simple like this

Checked all the 6 pcie slots but no luck .In my mb bios there are two items related to gpu , one is for primary display and the other one is the choice between igd and pcie

always pin method worked for me sometimes bios chip is U11 and some other times U10 PINs that should shorted also might be different (2 types roughly)

You must short pins 1 and 5 on U10 chip. Short pins and power on your computer, after that you can take out short and flash your bios again.
Use DOS version of atiwinflash using -f option.

Playing around with the actual BIOS chip on the card sounds to extreme, complicated, and risky. What exactly have you done when you say you've "tried almost everything?"

First things i'd try would be to connect a monitor to the motherboard directly or to another GPU and try to boot using SAFE MODE. From there you should be able to access and at least display windows then just re-do the bios flash afterwards.
