Does anyone here can explain me after the flashing is done do we have to remove the solder wires? Or leave it as it is and if we have to desolder it how to desolder I am new to doing soldering/unsoldering

For flashing DeMux, the wires are only needed to flash the gMux IC. Once flashed, the wires can be desoldered, as they are no longer needed.

After the flashing is done is Bootcamp (Window) possible to be installled? I wanted to do a dual boot on my macbook pro 2011 17" using Mac OS and Bootcamp (Window). Thanks

Did you test it?
It won't work because bootcamp will not boot in BIOS mode :(
I tried UEFI mode, but this causes a bsod all the time.

I haven't test it yet. If we use UEFI mode will it work but I know that using UEFI mode will cause something with the audio issue that Audio wont be working right?

You may want to check your thermal paste/heatsink/fans.

I have checked and reapply the thermal paste and I am not sure is it possible to Disable the SIP? I try to disable SIP but what happen was after the login screen when I typed my password and enter the computer automatically shut itself so is there a way to Disable the SIP? I wanted to connect this device with an external GPU (Akitio Node + AMD RX580 ).

Thanks

So I was able to successfully run the EGPU into this macbook pro 2011 and disable the SIP I dont really understand what was the real issue but if my macbook did something that need to restart after the restart while logging in it will always shut down itself but this was solved by waiting around 30minutes later for it to cool down or whatever and it works. But currently EGPU works on the Macos.

I can get it for you later today when I get home from work, if somebody doesn't get in first that is. Or you can just google for the board view file.

So did you get a successful flash?
I soldered to that point all good there but still wouldn't flash tried everything just one of those stubborn boards, I ended up banging it on the ACHI IR and brought it back to life temp fix I know but it will pull the guy out of a hole for a bit.
I was talking to dosdude an he was kind enough to refund nice guy 👍 if I get another for repairs I'll try again I'd like to see this up and running.
