hello everyone, well I have a cuh7215b model ps4 proconsole and I can't connect to the network via lan or wi fi at all and it makes it impossible for me to test it or test what the community does having so many features in linux, my kernel that I have tested is baikal , I have also tried many OS, most of them do not start anymore, only white light, in addition to the message no directory is found, and I tried with the alternative method through the linux terminal and one or the other works for me, but it never works for me, for example, iso image like gentoo's and I see that there are not many functional baikal kernels, I found one on reddit https://gbatemp.net/threads/baikal-kernel-for-cuh-7215b-9-00-with-usb-network-dongle-support.605944/ but the network connection does not work for me either, someone who has a solution or the same problem and has solved it, thank you very much

Can you quickly give me a list of all the kernels you have tried and the output of whosthatsouthbridge - https://ps4linux.com/ps4-linux-documentation-aio/#How_to_use_whosthatsouthbridge_to_find_if_my_PS4_is_Aeolia_Belize_or_Baikal

my ps4 is baikal but with the belize kernel something works for me, the tested kernels are baikal By psxita By ps4boot & mircoho By ITmania but both give me a black screen, the ones that have booted me are the kernels of By ps4boot & mircoho By codedwrench, in addition to this kernel modified by this user https://gbatemp.net/threads/baikal-kernel-for- cuh-7215b-9-00-with-usb-network-dongle-support.605944/ from reddit https://www.mediafire.com/file/25ieddloil1f57d/5.3.18_BALTIKA.zip/file , if you could see that blog, It was the first one I tried and it worked but without any network

SamuelBC It seems like your only option would be to use the kernel from gbatemp and get a USB WiFi adaptor.

ok , again installing one or the other Os currently i have my ps4 cuh 7215b using a network dongle but i absolutely have no access to bluetooth even installing dependencies etc , my usb dongle is a csr 5.0 it is chinese , i made it work in a linux virtual machine but in case I tried Pop _ OS or steam Os but it does not recognize me in the distribution for the ps4, open a way to make it work??? noob404

Hi there, If a Belize kernel has worked for you to boot into Linux then you must have a Belize chipset as your CPU. It would not boot into Linux if your CPU was not Belize. I too have a CUH-7215B PS4 Pro and Belize type kernels only work for me. Double-check "Who's_that_SouthBridge?" on the jailbreak html window just to be sure.

SamuelBC Have you done this already?

"Who is that SouthBridge is Baikal

They are my dongles that I try that work by not having bluetooth or wi fi or lan on my console ethernet AX88179 cambridge silicon radio ltd. bluetooth driver HCI MODE

LINUX, I can not connect to the network neither by lan nor wi fi ps4 pro CUH7215B

CUH-7215B is notorious for not having bluetooth and wifi not working. This is a common issue.

As for the LAN, that should work for your model without an adapter.
Are you using this "Whos_that_southbridge?" on this exploit host = https://jb.ps4linux.com/

For the record, I have tried other exploit hosts for "southbridge" and they too have given me the "baikal" response when in fact my chipset was a "belize" chip for the CUH-7215B.

THough this is for 7216B, try this - https://ps4linux.com/forums/d/59-right-bluetooth-firmware-for-ps4pro-7216b-users-and-maybe-more

Hello, I'd like to be a donor to get this problem fixed. Specifically the problem with WiFi and Bluetooth for the CUH-7215B. Which team or person will accept funding for this?

noob404

Novice4321 Contact me on Discord if you are ready to be a tester and donate for the cause.

Zabovis

Novice4321 @noob404
As also a frustrated owner of a CUH-7215B Pro (Black) model. I am also willing to be a donor and developer-aid in this project.
My skills with Linux are intermediate and the fact that I also possess a CUH-7215B could prove my contributions to be useful.

If any of you two are interested, please let me know. I am also on the Discord server. Discord Name: (Zabovis)

So I'm in the same CUH-7215b "woes of the pro" boat. The best I have come up with is using an android device in tether mode. Posting this from psxitarch v3 on ps4 pro. 🙂

Zabovis

misfit-mischief
Hi misfit,

For research purposes, could you please post the model and make of your android device?
Thanks

Novice4321

I have the same distro. I'll try this as a temporary solution. Any special instructions on tethering Android? Much appreciated!

misfit-mischief

Novice4321 as long as the device supports usb tethering its pretty much plug and play once you turn on tether mode
if this doesnt work it could be the bzimage youre using

Novice4321

noob404
Absolutely! Let's fix this! Just installed discord. How do I contact you?

noob404

Novice4321 If you haven't yet, join the Discord using this link. PM me ( I am Noob404 on the server). We will discuss the details there. Before we begin, I would like to be absolutely clear that this might not work at all. Driver issues are tough to fix on PS4. So, I cannot guarantee anything. And, please also understand that I am currently working on another project too. So, you will have to be extremely patient. I will try my best though. If that's ok, please do contact me on Discord.

Invite is out.✌️

Zabovis That's awesome! I think it'll be great to have you. Noob404 and I have made contact on discord. I'll defer to him on how to get you involved as I'm more a donor/tester with little experience.

noob404

Zabovis There are two Zabovis on the server. Please confirm your user ID too.

Great news everybody. I figured it out. I confirm it works with my CUH-7215B Belize Pro model.

Bluetooth headphones and controller work flawlessly.

As for the Wi-Fi, I believe the same procedure has to be done. Find the missing Wi-Fi firmware file and add it to the initramfs.

Zabovis Sorry, didn't see this til just now. The android device is an old galaxy tablet, GT-P5210.

@noob404 @Novice4321 @tastebin

I think I've stumbled upon a much deeper problem than just the Bluetooth and Wi-Fi drivers not working properly...
There's a fundamental coding error or compilation error with Hippie68s initramfs file.

Look at provided kernel string: [ 64.790335] Bluetooth: hci0: Firmware already downloaded
See also below picture:

As you can see from the directory ~/lib/firmware/mediatek/mt7668pr2h.bin is already there.

If I'm correct in my assumptions... this means the initramfs file is NOT loading the already installed drivers of the Linux distribution.
If the initramfs file gets fixed, then this could mean a MASSIVE improvement for PS4 Linux. Not just functionality wise, but also PS4 Linux gaming....

Or there’s a fundamental problem between how the kernel communicates with the initramfs file.
