PS4 MT7668 modified internal HDD initramfs, please help

t0nito

So I followed Modded Warfare's video on how to install Linux, everything went fine but Wifi and Bluetooth doesn't work, after doing a bit of reseach it seems that regular kernels and initramfs files don't work with the MT7668 wifi adapter that I've confirmed my PS4 has. My PS4 is a slim with a belize2 A0 southbridge. So I've found the modified kernels and initramfs files with these drivers, the problem is that I have it installed on my internal HDD and it seems that there's aren't prebuilt initramfs files for internal installations and you have to build your own by modifiying your existing one, now this seems it's a bit out of my league and I'm not able to build my own, what I ask frrom you is if you could kindly build one for me.

I have the modified 5.15.15 belize kernel now the only piece missing is a modified initramfs that works with an internal HDD install

This is the the internal HDD file I'm currently using: https://www.mediafire.com/file/wziaiuqttxlwwgp/initramfs.zip/file

If you could kindly build me an internal HDD modified initramfs file I'd be very grateful, I can't find any prebuilt one so this would be useful for other people in my situation

Thank you

Also when I tried following this guide here: https://ps4linux.com/ps4-mt7668-wifi-bluetooth-kernel-inbuilt-drivers-fedora-arch-ubuntu/
When I get to this part "git clone https://github.com/noob404yt/mt7668-wifi-bt-firmware.git" it's asking for username and password

I got though that stage but I'm getting some permission errors:

When unpacking:

cpio: dev/console: Cannot mknod: Operation not permitted
dev/console
dev/.keep
cpio: dev/tty: Cannot mknod: Operation not permitted
dev/tty
cpio: dev/zero: Cannot mknod: Operation not permitted
dev/zero
cpio: dev/urandom: Cannot mknod: Operation not permitted
dev/urandom
cpio: dev/null: Cannot mknod: Operation not permitted
dev/null
cpio: dev/random: Cannot mknod: Operation not permitted
dev/random

And then on the last stage:

sudo find . | cpio -o -c -R root:root | gzip -9 > /home/initramfs.cpio.gz
bash: /home/initramfs.cpio.gz: Permission denied

I'm using an USB boot version of Linux Mint

I give up. I guess this just isn't for me. I erased everything and started from scratch following this guide: https://ps4linux.com/fix-mt7668-wifi-bluetooth-ps4-7215-7216-belize-baikal/

I was happy I finally had wifi and bluetooth showing up only to be immediately dissapointed again. Wifi says connected to network but doesn't work, bluetooth is enabled but won't find any devices.

Not worth the frustration... Thanks for the help anyways.

Hey man i remember me and noob404 were talking about built in kernel firmware sometime ago, he says he has issues with it but i dont so let me give you some random kernels that come with firmware plus drivers from here: https://gitlab.com/ChalesYu/mt7668sn/-/tree/0ff0c219215ea0f865eea6b45b5f575f2a01bcb5
I had a Makefile specifically to make these drivers kernel built-in but i did ont back it up before my Windows broke down and I had to reset, i still remember pretty much all the edits i made and can re-edit the Makefile again for kernel-building-in but im too lazy for it now
I used the mt7663 combo chip driver (code comes from commit for linux 5.15) which had longer maintenance rather than those old mt6632 ones (im suprised it compiles for 5.x at all)
here is the kernels i made with them with low latency config:
xanmod low latency (not yet booted by me):https://www.mediafire.com/file/4paxsn3qzqgymdi/bzImage/file
tkg low latency (this one is booted by me):https://www.mediafire.com/file/fe8kvxol1j689k3/bzImage/file
clearlinux optimizations (not yet booted by me):https://www.mediafire.com/file/yoapbaxqshdyqgz/bzImage/file

abcdefg123 also i see wlan does not log any warning/error stuff or whatever mumbo jumbo at boot so i assume the mt7663 combo chip drivers are less finnicky than the mt6632 combo chip drivers used by kernels from other people but they both work just fine and the same to the extent that i have used them. If you are wondering why there is a mt6632 driver and mt7663 driver even though it is for chip mt7668 the answer is that they are both combo chip drivers which means you have the option to build for other chips
