// This SSDT is essentially sending "CAP_EXP+10.w=0052" as well as a RST() call | |

// that this code will work for you as well. Read below for instructions for other brands. | |
// There might be issues when going out of sleep mode? I vaguely recall | |

// "CAP_EXP+10", on my system, is located at the PCI address "@80", which is 0x50 in hex. | |
// This is the 0x50 you see in the OperationRegion declaration below. | |
// In order to find your actual PCI address (which should NOT be different, but just in case...), | |
// you first need to use Linux, and find your PCI address (e.g.: 0000:3b:00.0) via `lspci`, and | |
// then execute this command (replacing "0000:3b:00.0" with your own PCI address!) | |
// setpci -v -s 0000:3b:00.0 "CAP_EXP+10.w" | |
// On my end, the result is "0000:3b:00.0 (cap 10 @70) @80 = 0142" | |
// The interesting info, here, is that "@80", being the address of "CAP_EXP+10". | |
// Convert that value to hexadecimal (80 => 0x50), then put it in the OperationRegion. | |

As long as your card is a Fibocom L850-GL, it should with no issues.
The memory offsets might be different, which is why I provided instructions using Linux to figure out your own offsets, as well as what to change in the code. Please refer to the // FOR OTHER BRANDS / OTHER MODELS

i got an error while trying to compile dsl
32, 6156, Invalid OEM ID (Length cannot exceed 6 characters)
any suggestion?

@BloodLancet Huh, I've never seen that error before. Simply swap this line:
DefinitionBlock("", "SSDT", 2, "HeySora", "WWAN", 0)
with a shorter OEM name (4th parameter of the DefinitionBlock
), such as
DefinitionBlock("", "SSDT", 2, "Sora", "WWAN", 0)
i got an error while trying this command setpci -v -s 0000:3b:00.0 "CAP_EXP+10.w"
in my lspci i got : 03:00.0 Wireless controller [0d40]: Intel Corporation XMM7360 LTE Advanced Modem (rev 01)
i'm not quite familiar with linux, may i get some help here?
If what you're getting out of lspci
is "0000:03:00.0", then you need to do setpci -v -s 0000:03:00.0 "CAP_EXP+10.w"
.
The 0000:3b:00.0
part is what needs to be replaced with whatever address lspci
gives you.
I got setpci: 0000:03:00.0: Instance #0 of Capabilty 0010 not found - there are no capabilities with that id
Please make sure you are typing the command correctly and not adding spaces where there shouldn't be. The syntax has to strictly match.
I unfortunately cannot assist you further, as I do not own your model of laptop.
Hey man, I got the same response like 'BloodLancet':Instance #0 of Capabilty 0010 not found - there are no capabilities with that id.
I try a lot but it remains same, could you explain the meaning of "CAP_EXP+10.w" and what exact the effect mean, is there another way to get this offset by command like "CAP_PM" or "CAP_MSI", it is really frustrated that I have been stuck in things like this for days, hope you could help me.
Anyway, thinks a lot for your good work.
I doubt the @80 you mentioned in the dsl file means the decimal No. shows in Ubuntu, the first No. I got by lspci and setpci is 40, however hexadecimal 0x28 then was used, but it ends bad, remains no work
If you cannot find any capability called CAP_EXP, that means you have a variant of L850-GL that is not compatible with USB-MBIM; which unfortunately makes your hardware not compatible with this SSDT. There is nothing that can be do neto assist, as this SSDT focuses on the (vast) majority of L850-GL/XMM7360 modems that are able to switch into USB-MBIM.
Without that capability, your card cannot be used on macOS, period.
Alright then, I would purchase a usb model like em7430 to realize the wwan function, but now I should mod the bios and release the white list first. It seems the only way to get wwan function in my laptop in different OS (MacOS, Ubuntu and Win).
how can I find my device's value is "RP07" or other
awesome work , mind share how to remove the fcc lock?thanx in advance
does this works on lenovo t580?
