LG Stylo 3 Plus Custom ROM – Lineage OS, AOKP, AICP, RR & Incipient OS Installation Guide + Review

As of now, there are 5 Custom ROMs for LG Stylo 3 Plus which are Lineage OS, Resurrection Remix, AOKP, AICP, and Incipient OS.

In this post, we’re going to install and test each of these to check out which one is a stable ROM and can be used as a daily driver.

Out of these, the most popular is the Lineage OS. Rest of the Custom ROMs are based on Lineage OS itself with added features and customizations.

Let’s check out how to install Lineage OS custom ROM on Stylo 3 Plus and what extra features we get as compared to LG stock ROM.

NOTE: Before moving further make sure that you’ve installed TWRP Custom Recovery on your Stylo 3 Plus.  For Lineage OS, AICP & Resurrection Remix, 32-bit TWRP is required. However, for AOKP and Incipient OS, 64-bit TWRP needs to be installed.

How to Install Lineage OS Custom ROM on LG Stylo 3 Plus MetroPCS MP450 / T Mobile TP450

After CyanogenMod, Lineage OS is the most preferred custom ROM. It gives stock vanilla Android experience. It is lighter, faster and free from bloatware as compared to LG preloaded ROM.

LG Stylo 3 plus is the not in the official list of Lineage OS supported devices. As its an unofficial port, some of the features are not working. I found that NFC keeps on turning on and off on its own and doesn’t work. VoLTE doesn’t work as well.

If these features are a deal breaker for you, Lineage OS cannot be your daily driver. But at least you can give it a try to get a feel of it.

We can divide the whole process into 3 steps for ease of understanding  –

STEP 1:  Creating a Backup in TWRP & Flashing Lineage OS 14.1 Custom ROM

Let’s start by downloading the necessary files needed for flashing.

1.Lineage OS Custom ROM zip File –  Thanks to messi2050@xda for making Lineage OS custom ROM for Stylo 3 Plus. You can download the zip file from below link

Google Apps Package zip file for Android 7.1 – You can download this file from http://opengapps.org, by choosing “Platform” as ARM, Android Version As 7.1 & Variant would be as per your requirement.  You can also download it from the below link. The below one is a very basic Google Apps (Pico) Package –

LG Stylo 3 Manual PDF – MetroPCS, Cricket, Boost Mobile, Straight Talk etc

User Manual is not a part of the package anymore as it only increases the size and weight of the cell phone box. After all, a User guide can be downloaded quite easily on the phone itself in the form of PDF, as and when required. Who is going to carry the hard copy along with the cell phone everywhere?

If we talk about LG Stylo 3, it’s available with almost every prepaid carrier in the USA for every variant there is a different manual. I’ve collected all the User Guides at one place for each and every variant of Stylo 3 in PDF form. It’s available for download in English & Spanish Language. Go ahead and download your respective copy from the below download link –

Stylo 3 Plus also comes with double the internal storage capacity with respect to Stylo 3.  Stylo 3 Plus has 32GB of internal memory.

The final plus point is that Stylo 3 Plus supports NFC (Android pay) which is missing from all other variants of LG Stylo 3.

The battery capacity is however reduced to 3080 mAh as opposed to 3200 mAh battery on Stylo 3.

LG Stlyo 3 Plus Root Android 7 MetroPCS & T-Mobile Tutorial

Gone are the days when we used to root our phones in one click with an android apk file without using a computer.  Kingroot was a popular rooting app until Android Lollipop. However, today most of the phones cannot be rooted even using a computer.

Even if we talk about LG Stylo 3, it is released by almost every US prepaid carrier including Boost Mobile, Cricket, Straight Talk, Tracfone, MetroPCS, T-Mobile etc.  However, except MetroPCS/T-Mobile all other variants of Stylo 3 are unrootable due to the locked bootloader. Correct me if I’m wrong. As I own MetroPCS variant of Stylo 3 I was able to root it quite easily.

Let’s check out how to root LG Stylo 3 Plus with the help of this easy to follow tutorial –

How to Root LG Stylo 3 Plus MetroPCS MP450 / T-Mobile TP450

The pre-requisites for rooting LG Stylo 3 Plus are –

  1. Unlocking the Bootloader
  2. Flashing TWRP Custom Recovery

Now that you’ve flashed TWRP we are good to go.

First of all, Let’s download the necessary files required for rooting –

SuperSU – The classic superuser root app by Chainfire. You can download its flashable zip file from the below link

DOWNLOAD

Magisk – A more advanced rooting app made by topjohnwu. It’s a systemless root which can work in hidden mode without affecting apps which don’t work on a rooted phone such as banking app. Download its flashable zip file from below link.

DOWNLOAD

Magisk Manager – We’ve to install this apk file manually after flashing the above zip file in TWRP. Download the apk file from below link.

DOWNLOAD

Remember that we’re going to flash either SuperSu or Magisk. We cannot keep both at the same time. Now, Let’s start the rooting process.

 

We can divide the whole process into 3 steps for the ease of understanding –

STEP 1: Making a NANDroid Backup in TWRP

First of all, we’ve to boot into recovery mode to access TWRP –

To enter recovery mode –

Turn off the Phone

Press Volume Down + Power Button to boot the phone. Once the phone vibrates, release the power button and hold it until you’re the white “Factory data reset” screen as shown below.

 

Press volume down key to move from No(Exit) to Yes. Now press power key to confirm this action

Once again press the volume down key and confirm with Power key.

 

 

Press the power key once again to bypass unlocked bootloader warning

Now, wait for TWRP to load as shown above.

 

Tap on “BACKUP” and select the files you wish to include in your backup

Now click on “Select Storage” and choose whether you wish to store the backup in Internal Storage or Micro SD card.

 

\

Swipe the bar towards the right to initiate the backup process

Wait for the Backup to complete.

Once done, connect your phone to PC via USB Data Cable.

STEP 2 :  Flashing the Magisk.zip Root File via TWRP

Wait for the MTP / File Transfer driver to install.

As the TWRP is written for a different LG phone model it’s detected as LGMS550.

The driver is installed and now we can transfer the necessary files to our phone’s internal storage.

Select the downloaded files and “Send to” “LGMS550” as shown above.

TWRP LG Stylo 3 Plus Custom Recovery Flashing Tutorial – MetroPCS / T-Mobile

After unlocking the bootloader of LG Stylo 3 Plus we are ready to flash TWRP (Custom Recovery).

We cannot root our Stylo 3 with stock recovery and after flashing TWRP rooting would be a one-click process. So without wasting time let’s do the needful.

Before moving ahead make sure that you know how to enter into the recovery mode. You should get a hang of it because after writing twrp recovery file in the fastboot mode we need to enter recovery mode in one go without fail else the whole process needs to be repeated. Go through this post to learn how to enter recovery mode on LG Stylo 3.

 

How to Flash TWRP on LG Stylo 3 Plus

Let’s begin by downloading the necessary files first –

The first one is Minimal ADB & Fastboot – This must be already installed on your PC if you followed the bootloader unlocking tutorial. Download the setup file from below link and install it on your PC. Thanks to shimp208@xda for making this awesome tool.

DOWNLOAD

The second file is no-verity-opt-encrypt-6.0.zip file. After booting into TWRP for the first time we’ve to flash this file else stock recovery would replace TWRP on next boot. Download the file from below link

DOWNLOAD

The last file is the custom recovery file which we’re going to flash in the fastboot mode. Thanks to messi2050@xda for making TWRP for LG Stylo3 Plus.

Download and save this file as well as the previously downloaded files on your computer

DOWNLOAD

 

 

NOTE:  To flash a 64-bit Custom ROM on LG Stylo 3 Plus, such as AOKP and Incipient OS, 64-bit TWRP needs to be installed.

The download link for 64-bit TWRP for Stylo 3 Plus is as follows –

DOWNLOAD

 

You can go ahead with the 32-bit TWRP installation as of now, and can flash 64-bit TWRP later on as and when required for flashing 64-bit Custom ROM.

 

STEP 1: Copying TWRP recovery file to Minimal ADB & Fastboot Folder

You can see I’ve saved the downloaded files in the same folder as visible in the screenshot above.

Let’s install Minimal ADB and Fastboot if not installed yet.

Finish installation but there no need to launch the program as of now.

Rename the downloaded TWRP custom recovery file to something easier.

I’ve renamed it as “recovery”.

Copy the “recovery” file. We need to paste this file into Minimal ADB and Fastboot folder in C: Drive or wherever you’ve installed Minimal ADB and Fastboot program.

 

NOTE: For Flashing 64bit Custom ROM’s such as AOKP and Incipient OS, 64bit TWRP is needed

I’ve installed Minimal ADB and Fastboot in Local Disk (C:).  Open C: Drive on your computer.

Double Click on Program Files folder to open it.

Look for “Minimal ADB and Fastboot” folder and open it.

Paste the copied “recovery” file in this folder.

Click on “Continue” to provide administrator permission.

Now that the TWRP recovery file is copied to Minimal ADB and Fastboot folder, Let’s proceed to the second step.

 

 

STEP 2: Writing TWRP recovery file in Fastboot Mode

Run the Minimal ADB and Fastboot program.

It would launch cmd command prompt window as shown above.

Turn ON “USB Debugging” on your Stylo 3 and connect it to the computer via USB data cable.

Refer to this post if facing some issue – LG Stylo 3 Bootloader Unlock Tutorial

Type adb devices and hit Enter on your computer keyboard.

It should list your phone as shown above.

The connected adb device is visible as “LGMP450” i.e LG Stylo 3 Plus MetroPCS

Now we’ve to boot our Stylo 3 into fastboot mode to flash TWRP custom recovery file.

To enter fastboot mode type  adb reboot bootloader  and hit Enter

Now your phone must be in Fastboot Mode.

Type fastboot flash recovery recovery.img and hit enter

 

NOTE:  If you’ve downloaded 64-bit TWRP image for flashing, you need to copy it to “Minimal ADB & Fastboot” folder in the same manner as explained above.

As the 64-bit TWRP image file name is recovery64 the command line will change to fastboot flash recovery recovery64.img

 

 

The TWRP custom recovery is flashed in 0.755 seconds!

Let’s move ahead to the next step

LG Stylo 3 Plus Bootloader Unlock Tutorial – MetroPCS MP450/T-Mobile TP450

Nowadays only a few of the carriers allow unlocking the bootloader and MetroPCS/T-Mobile is one of them.

Bootloader unlocking makes the rooting process easier and in turn, it lets us install various custom ROMs thus making the phone more useful. As Stylo 3 Plus belongs to MetroPCS/T-Mobile, the bootloader can be unlocked quite easily.

Let’s check out the process of unlocking the bootloader on Stylo 3 with the help of the following screenshots –

How to Unlock LG Stylo 3 Plus Bootloader MetroPCS MP450 / T-Mobile TP450

By turning ON OEM unlock, Google’s Factory Reset Protection (FRP) gets disabled.

Now that we’ve enabled USB Debugging & OEM unlock we’re ready to connect our phone to PC for the installation of ADB Interface Driver.

Step 2: Installing ADB Interface Driver & Authorising the PC for USB Debugging

Connect your Stylo 3 Plus to the PC via USB Data Cable.

The USB Connection mode should be set as “Charging” or “File Transfer”.

Wait for the ADB Driver Installation to finish.

If the driver fails to install on its own, we’ve to install it manually.

Follow this tutorial for manual ADB driver installation.

Now that we’ve installed the ADB driver on our PC, we’ve to authorize our PC for USB Debugging

We’re going to use a simple program called “Minimal ADB & Fastboot” to write ADB command for bootloader unlocking.

You can download “Minimal ADB & Fastboot” from the below download link –

DOWNLOAD

Install Minimal ADB & Fastboot program on your computer and run it.

It would launch the cmd command prompt window.

Now in cmd window, type adb devices as shown above and hit “Enter” key on your computer keyboard.

 

As soon as you would click “Enter”, a pop-up would appear on your phone screen asking permission to “Allow USB Debugging”

Tap “OK” to approve it.

You can see the connected phone is detected as LGMP450 but it’s “unauthorized”.

As we gave permission in the previous step to Allow USB Debugging, this time the adb devices command will show it as “authorized”

So again type adb devices and hit Enter.

Now we’ve successfully connected our Stylo 3 Plus LGMP450 in ADB mode and we’re ready to boot into Fastboot Mode for Bootloader Unlocking.

  1. ADB Driver installation when connected in Fastboot Mode 
  2. USB Modem & Serial Port Driver Installation when connected in Download Mode
  3. MTP Driver installation when Stylo 3 is connected in File Transfer mode 

 

Let’s start with the installation of ADB Interface Driver. Many users face issue while installing this driver.

Accept the installation warning by tapping on “Yes”

The driver installation is successful.

The ADB Interface driver is now visible in the “Device Manager”.
