[LG V30 Guides, News, & Discussion] Saxithon:
So, this is how I PERSONALLY got a pretty decent experience on phhussons P GSI.

I am not responsible if something doesn't work or doesn't work the way you want.

Update: The PixelExperience build over on the Treble section works pretty well and eliminates the need for Overlays_Pr1.zip as well as Bitgapps. It's also including gapps (with SetupWizard as well as the pixel launcher). Same bugs as listed below.

Step 1: Trebleizing your phone

Download the latest trebleized Lineage OS ROM by SGCMarkus here and install it.

Make sure to read his guide to repartition your device carefully, otherwise this won't work.

Step 2: Prerequesites to have a nice time with Android P.

Before we wegin with the GSI stuff, you will have to copy the build.prop [or if you have the device fingerprint for your phone, just copy that] to a safe location.

Step 3: Installing the GSI

Download phhusson's latest Pie GSI from here

Unzip it and load it onto your phone's storage.

Proceed with wiping your /system, /data, /cache and Dalvik. Do not wipe /vendor (duh.)

Then install the image by tapping "Install image" button in the selection screen.

Step 4: Installing GAPPS

Download BitGapps from here. (I do **not** recommend using unofficial OpenGapps, as I run into several issues with them.)

[This version of GApps does not include any SetupWizard, which means you will have to download all your apps manually!]

Step 5: Fixing Device not Certified

While the notification doesn't pop up, it is indeed not certified and is (one of) the reason(s) why the phone gets so hot sometimes.

So what you need to do is download Magisk 16.7 (or later) as well as MagiskPropsHideConfig from here

as well as get any terminal app from the Play Store you like. [I personally like Material Terminal, as you can copy/paste in it]

After doing that, open a terminal window and type "props" (without quotation marks). Then select 1 and enter your device fingerprint (either from the build.prop we saved earlier or the fingerprint you saved somewhere)

Step 6: Makin' it nice.

So most of this besides maybe the Vibrator are purely optional, so you can go and enjoy some Pie if you wish.

Vibration:

- reboot to TWRP

- mount /vendor

- Install SGC's sGSI fix from here

- Install temp_vib_fix_joan_v2.zip from the attached files. Doesn't fix the dullness that occurs after some time.

DT2W:

- reboot to TWRP

- mount /system

- Install dt2w_on_gsi_joan.zip

Proper rounded corners and that new navbar[not required on PE P GSI]:

- Reboot to TWRP

- mount /vendor

- Install Overlays_PR1.zip from the attached files. (not mine, it's from erfanoabdi's Telegram group, will add proper credits if i manage to find the creator)

- Navigate to Settings -> System -> Gestures -> Swipe up to home

Additional System Accents (Yay! Colors!)

- Reboot to TWRP

- Install System_Accents_P.zip from the attached files. (not mine, it's from erfanoabdi's Telegram group, will add proper credits if i manage to find the creator)

Always-on Display (DT2W still works!)[Not required on PE P GSI]

According to phhusson, this does more than just enable AOD apparently, and it does something with the vibration, so installing this is on **your own risk** (not like it wasn't anyways)

-Reboot to TWRP

- Install P_AOD_FIX_-_by_ElHechicero.zip (not mine, credit goes to ElHechicero)

Getting Wellbeing [Not requried on PE GSI]:

-Download the Wellbeing.apk from ApkMirror

-Rename it to WellBeing.apk

-Move it into /system/priv-app/WellBeing/ (create the folder WellBeing)

-Reboot

Getting a nicer launcher with the appdrawer[PE P GSI uses the Pixel Launcher]:

-Download Nokias (HMDs) Launcher from ApkMirror

-Rename it to Quickstep.apk

-Replace /system/priv-app/Quickstep/Quickstep.apk with the Nokia launcher (which you renamed to Quickstep)

-Reboot

Issues:

- A lag when tapping on the "Default Apps" or the Bluetooth/NFC area in Settings

- Can get warmer when in playstore

- Vibration: Gets dull and sounds like static after a while. Hopefully SGCMarkus will be able to fix this or we'll be stuck with the dullness on P gsi's for now.

Not working:

-Hotspot

-NFC (?) [Seemed to work just fine on my device]

- Let me (or others, rather.) know.
