Macbook Pro 14,3 and Fedora firmware file


So want to attempt to try this WiFi fix on my MBP 14,3. I am quite new to Linux and especially firmware changes. Not sure how exactly to edit and save the file changes. I went to the folder in terminal then ran
Code:
gedit brcmfmac43602-pcie.bin
.

It then opened up but there were some hex like symbols. I did manage to find the one instance where ccode was X0 and also where regrev was 15. Found a number of other instances but the values were different. So guessing there is only the 1 instance of each to change.

I tried saving and said I wasn't allowed. Sorry if this is really newbie and simple fix but I am sure once I get the WiFi working then everything else will be smoother to fix.

So had permissions issue saving. It also warned that I might corrupt the file. So tried doing sudo -i and as root tried to run gedit command but get some kind of unable to init server, gtk warning cannot open display.

there is a learning curve issue here. you have several things to learn before you can make use of this .bin

the only thing you can do is go back to who offers this ".bin" for specific instructions of use. in this case you need to know if Fedora supports using the .bin and how to place it so that Fedora is aware of it and uses it. it may be true that directions for a different OS (not fedora) works: but might not, might even do damage. if you can't find instructions specifically for fedora then hold off using it for a while until you "know more about it".

it's really NOT SAFE to use ".bin" you've found from anywhere on the net. did you get this file on REDHAT (or did fedora)? is it check-sum'ed (verified) to be a file that either RedHat or Apple released? if not: it could contain trojans or spy ware.

my overall advice is run linux on it's own box, don't try to mix the two together because you might damage your mac. the exception would be if you have a "fast mac" and have ability to restore mac and linux if they crash, and understand that in the end you might have to buy a mac if you 'kill it' by accident.

The .bin file was in the distro already haven't installed anything. So I assume that means it is supported in some way?

Thanks for the heads up though, I am concerned touching the firmware stuff but really want Linux at the same time

Edit: yep the file is definitely part of the fedora official download
