[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SGCMarkus:
​

LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1 (Nougat), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit our Gerrit Code Review.

Everything i forgot probably

As you can see on the "Working" list, this is a highly experimental build, flash at your own risk, and don't come crying to me if it should brick anything (it didn't for me, but seeing from the TWRP Thread the V30 can be picky).

Dont forget to make a backup!!!

If you want to report any bugs, NEVER do it without providing logs. I can't try to fix things without logs.

Helpful log commands:

logcat (usage: e.g. logcat > /sdcard/logcat.txt )

dumpsys (usage: e.g. dumpsys SurfaceFlinger > /sdcard/dump_sf.txt)

dmesg (usage: e.g. dmesg > /sdcard/dmesg.txt , might need root)

for more examples on how to use the commands, either google (do that first) or ask (only do this if you already googled how to use those commands).

FAQ

USB isn't working. How do I get logs?

In the ramdisk theres a nice little script which will print the logcat to /data/ramoops/cm14.1_<number>_logcat_<date/time>.txt

The logcat is many many hundreds of MB in size, why?

Its currently spammed with something like this:

E/QMI_FW ( 674): xport_reg Failed for service_id=0x35 version=0x1001 on 15

Replace

[0-9][0-9]-[0-9][0-9] [0-9][0-9]:[0-9][0-9]:[0-9][0-9].[0-9][0-9][0-9] E/QMI_FW ( [0-9][0-9][0-9]): xport_reg Failed for service_id=0x35 version=0x1001 on [0-9]*[0-9]

in the log with your favorite editor which can use regex with nothing (or delete all those lines if you have that option)

Is there another way to get some logs?

In Developer Options, turn on "Local Terminal", and get a logcat or other logs with that.

The screen glitches, is there a way to fix this?

I hope so, working on this too.

After restoring my backup with TWRP, my phone won't recognize my PIN (not SIM PIN). What todo now?

Just follow the guide on here. Afterwards you have to setup your PIN again (also Fingerprints, and enable Trusted Agents in Settings -> Fingerprints & Security)
