EM7430 shows 'No Service' and cannot install updates. Requesting assistance.

Hello, I directly refer to this tutorial to modify EM7430. Is that correct?

You can try, i didn’t try this before

I am currently DW5816E, can I directly upgrade the EM7430 universal firmware on Linux?

Have you tried those procedure?

我现在使用Ubuntu系统,lsub可以看到sw5816e的网卡,运行 [autoflash-7455.sh]脚本,提示没有网卡。

我现在不知道该如何操作了,我想让这张卡正常运行起来,我不太懂该如何操作。

seems it cannot detect the VID/PID of the module

413C 81CC 是对应的模块,现在模块无法正常工作,我是否需要在Ubuntu上安装驱动?

you can have a look on the script:

你可以帮助我远程设置一下吗?,现在模块不能正常工作,我不知道我该如何操作,我并不是专业的开发人员,我只是一名爱好者。

For the driver, you can try this one:

我下载了这些文件,但是并不知道如何在Ubuntu系统中运行它们

have you read the readme.txt file?

This forum is more for developer, you need to have some basic technical skill…

我并不知道readme.txt在哪里,我有一些基本的技能,但是好像在这里并不太适用,我的英文太差了

you can ask Deepseek to translate

e.g. MBPL_DRIVERS_R40_ENG3-usb-pcie-src\usb\readme.txt

How to Build the driver

run “make” to generate the driver binaries: qcserial.ko, usb_wwan.ko and qmi_wwan.ko

How to Install the driver

  1. run “make install”

我在终端输入make?不需要别的参数吗?make install在哪里?

i think you need to first get some tutorial on how to compile driver in linux

好的,谢谢,我先去学习一下,打扰您了,感谢您的帮助

您好,方便放我看下驱动是否成功安装吗,我在usb目录使用终端输入命令make,然后make install 都是正常的,我总觉得驱动不太正常,缺少端口,不能使用at命令

what did you see when connect the module to linux in dmesg?
