[HELP] Possible WWAN Card Implementing Method

EigenTom commented 3 years ago

I've been working on implementing WWAN Card on X1C 6th for a long time, and eventually found some resources which may be useful to eventually drive up specific WWAN Cards on this platform.

I've tested Sierra Wireless EM7430 / EM7455 on my machine. Now, both of them are able to be detected by the OS (Catalina 10.15.6), and I can try to connect to the network with SIM card inserted:

In short, you only needs to do 3 things to make it happen:

Flash the modded BIOS to bypass the WWAN WhiteList, make sure USB mapping is implemented properly (You does not need to if the whitelist is not triggered by the card)
Turn on your card's COM Port 6 and COM 8.
apply the kext driver in this repo

Reboot, then you should see the desired result.

I could have been tested whether this implementation is capable of driving up the cards completely, but I have two problems to fix which I just have no time to fiddle with:

I did not have any WWAN antenna which suits this machine currently, resulting in not being able to receive any LTE signals
I'm not familiar with the APN settings in macOS: this is completely different than Android or Windows, and I have no idea how to configure them to suit the carriers in China Mainland.

Therefore, I'm asking for help to verify whether this approach is capable of making these specific cards work on macOS 10.15.x or higher versions.

This looks great!

I'll order a WWAN card soon and check things out. I'm busy with life, however, so I probably won't be able to get back to you for another 2-3 weeks.

Thank you for letting me know about this.

Note:

EM7455 is for Americas & EMEA
EM7430 is for APAC

I've used Dell DW5809e (EM7305, 4G, work) with modded BIOS (whitelist removed) and kext driver LegacySierraQMI.kext, it got work and speed was good. The signal bus is USB signal.

Do you need to open port COM 6 and COM 8 of your card to make this patch work?
In my case, I implemented a modified version of LegacySierraQMI which injects the parameters of EM7430/EM7455 to make it recognised by the OS.
Yes, it must be USB. Cards working on PCI-E bus like L850-GL will not be able to drive up in macOS.
Seems like you are using CHN-UNICOM. I couldn't wait to try it with my SIM card inserted. How did you managed to figure out the APN settings?

1.No, I keep COM setting default. 2.I bought 5809e card because it's cheap and it have been tested in this repohttps://github.com/msbence/hackintosh-DellLatitude5400 3.Yes, my 5809e is working on USB bus only, but some of the wwan module have the option to switch into usb mode such as L850-GL. 4.Yes, but it seems like have no relation to the option APN, it will still work when I keep it blank or input something at random such as 11111

Looks great. EM7305 is pretty damn cheap (CNY 45~55) especially on Taobao and Idlefish(XianYu). I'm planning to purchase one for testing too ;-)

By the way, is your WWAN antennas the genuine one comes with this machine, or they are random compatible ones installed by your self?

Hi, buddy,

I have a dw5809e as well. But the signal always shows "NO SIM". would you share your LegacySierraQMI.kext.

for DW5809e, you can find the corresponding kext in this repo:

Great! I made DW5809e work finally.

However, it still has a problem, every time making a connection after a reboot, then WWAN successful connected, then it failed to connect after releasing the connection.

Any idea?

Hi,

I've already modded bios to remove whitelist but after some shutdown , reboot, maybe cold reboot, my X1C6 report error 1802.

My bios is 1.55, already modded. WWAN card is Dell dw5809e as you advise

Can you help me to fix it?

Beside that, I've EM7455 card but it can not connect, it shows Error. I tried to open port 6 or 8, but the error was same.

I confirm that EM7305 & EM7355 work fine in Monterey with kext LegacySierra

My steps to make X1C6 recognize them is swap in linux (sleep mode).

Boot into Ubuntu
Sleep
Insert these card
Using swi_usbcomp.pl to change to port 6
Using AT command to bypass X1C6 whitelist (AT!Custom="FASTENUMEN",2)
Exit "low power mode" by using command AT!pcoffen=2
Reset : AT!reset
Change ProID & VID in legacySierra kext to match with card's value
Restart and enjoy

Note: card EM7455 doesn't work in MacOS, I tried all ways but it still shows Error.
