You know there's a powershell script that you can just execute...?LOS auto updates these baseband. But you can flash the above latest baseband even before LOS integrates them(if you want to).
If you're on windows:
(Prereq: You need ADB installed on your machine and know how to use it)
Download the release file's zip, currently labelled as "latest" and extract it to a folder you can access (possibly your Downloads folder).
Go to that folder, and right click on ih8sn.conf, and click "Open With" and select Notepad
Edit the configuration with your desired results for your device and click save
Now you're ready to push the results. However, the push.sh is for linux, so right click on that file and open with notepad.
Now you can see the following, this is what you're going to type into your command prompt:
adb wait-for-device root
adb wait-for-device remount
adb wait-for-device push 60-ih8sn.sh /system/addon.d/
adb wait-for-device push ih8sn /system/bin/
adb wait-for-device push ih8sn.rc /system/etc/init/
adb wait-for-device push ih8sn.conf /system/etc/
This calls adb root which requires ADB Root in the developer options on your phone (not providing details on that)
Then it remounts the system (if you have issues, review the other issues)
It then pushes the files from your local directory to their respective folders.
You're doing some pretty "advance" things and thats why this is not beginner-friendly and no one but yourself is responsible if anything goes wrong.
I'd recommend you NOT do this and instead wait for proper documentation.
