Do you have to restore the stock Android OS on your LG V30? Maybe you need to reinstall the default Android firmware for fixing issues, or for restoring everything back to its initial state, or perhaps you just what to apply a new OTA that’s released by LG and Google. Well, all these update operations, and more, will be explained and detailed during the following guidelines.
Thus, this tutorial can teach you everything about the update procedures that can be completed on the LG V30. As already outlined, we will discuss about three different flashing operations: applying an OTA (and here you will have three different update methods exemplified), manually installing the stock / default Android OS and installing a custom ROM firmware.
The tutorial will be therefore divided into three different sections where each update procedure will be detailed. Now, on each section we will talk about advantages, risks and essential pre-requisites that are implied. Of course, the actual flashing steps will be detailed so that you can easily complete the update process for your LG V30.
Now, I recommend you to review all the lines from below before choosing to apply a certain procedure. Only in that way you can choose wisely the perfect update solution for your LG V30. Good; so let’s see what it’s all about:
Receive and apply OTAs on LG V30
OTAs are official Android updates released by Google and LG. An OTA is an ‘over the air’ update so we are now discussing about Android notifications that should be automatically received and applied on your LG V30.
Usually, an OTA is released gradually, in phases and for limited markets one – Google is first releasing the update and then LG is customizing it; lately, the software is provided for retails and carriers which will add a final touch to the Android update. Bottom line, some users might receive the notification sooner than others and that might become a real problem.
Moreover, an OTA can be received and applied only if your LG V30 is already running on official Android OS and only if its system hasn’t been yet tweaked. Otherwise, the only way in which you can still apply the official firmware is by following a manual process – the one that’s explained during the next section of this tutorial.
Applying a new notification is an official procedure supported by LG. That’s why it can be completed without using third party apps. Of course, you won’t risk to lose your phone’s warranty while flashing an OTA. Additionally, your data will be in safe hands during this update procedure, so a backup isn’t required.
Only one thing should be verified before anything else – your LG V30 should have at least 50% power left; otherwise you must plug in the charger before resuming the steps from below.
Now, if you know that an OTA is available but the notification isn’t received on your LG V30 you can try to force it down; here is what you need to follow:
- Power on your smartphone.
- Enable a Wi-Fi connection.
- Tap on Menu and go to Settings.
- Switch to About Phone and access Software version.
- From there you should be able to check for system updates.
- So, run this software scan and if an OTA is returned just follow on-screen prompts and complete the flashing process.
Another way in which you can apply an OTA on the LG V30 is by using the stock recovery image. In this case you must download the OTA file on a computer first (you can download the update package from any source you prefer). Then, you need to follow:
- Connect your phone with your computer with the help of the USB cable.
- Transfer the OTA file on your phone and then remove the USB cord.
- Switch off your handset and reboot recovery mode on your LG V30.
- From recovery select ‘Install zip from SD card’.
- Pick up the firmware file from your smartphone.
- Follow on-screen prompts and wait while the update is flashed on your handset.
- Reboot your device in the end.
Other update solution implies in adb sideloading the OTA file. If you choose this method you will need to install Android SDK on your computer: learn how to install Android SDK on Windows or how to set up ADB on MAC OS X / Linux. On your smartphone you will have to check the USB Debugging feature that’s located under menu – > settings – > developer options – hint: if Developer Options isn’t there, first go to About Phone and tap repeatedly on Built Number. Finally, follow the next steps:
- Download the OTA file and save it on desktop.
- Rename this file into ‘update.zip’ and transfer it inside the Android SDK folder.
- Power off your LG V30, reboot into recovery mode and connect it with your computer via USB cable.
- Access the Android SDK folder and open a command prompt window: press and hold the Shift keyboard key, right click on any blank space and select ‘open command prompt window here’.
- In the cmd window type ‘adb sideload update.zip’ and press Enter.
- The Android firmware should be now applied.
- In the end, close cmd, remove the USB cord and reboot your LG V30.
Manually install the stock / default Android firmware on LG V30
As already outlined before, if your smartphone is rooted or running on a custom ROM firmware, you won’t be able to receive the OTA. So, in that situation you will have to use the manual update procedure.
The same process should be initiated if you are tired to wait for the OTA roll out, if you want to restore your device back to its initial state or if you want to try to manually fix software related issues.
Shortly, manually updating your LG V30 will help you revoke root access, relock the bootloader, reinstall the stock recovery image and re-flash bloatware and other built-in apps and restrictions. Additionally, if you previously tweaked your device, now you can restore its warranty. And finally, you can fix the most common soft related issues such as boot loops, lags, bugs, screen freeze, signal strength problems, battery drain, heating situations, total blackouts and lot more.
As you can see, there are many advantages related with this operation. Now, similar with what we already discussed during the previous section of this update tutorial, this operation is official – supported by LG. Thus, you won’t have to use any third-party apps for completing the steps from below. The flashing program that will be used is developed and offered by LG, so from this perspective you have nothing to worry about.
A backup should be applied though – your personal files might get corrupted or wiped out while the full firmware package is being flashed. So, before doing anything else complete a general backup process on your LG V30. In that way you can secure everything that’s important for you: contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, IMEI / NVRAM data and more.
The update process must use a computer. There you will have to install the flashing program and download the Android update package. For making things work it’s essential to install the right drivers for your LG V30 on the computer that will be afterwards used. Also, on your phone you should enable Developer Rights and check the USB Debugging field just as already explained during the ‘OTA section’ of this step by step guide.
Don’t forget to charge your smartphone before doing anything else if that’s required – otherwise you can end up in soft bricking your LG V30 (different malfunctions can be caused if your phone will get switched off during the update operation).
Good; finally, follow:
- First, download the KDZ firmware package for your LG V30 – you can get the stock Android software from any source you prefer.
- Save the KDZ on desktop.
- Next, download the LG UP software on your computer; also install the flashing program by following on screen prompts.
- Remember to install your LG V30 drivers on your computer before doing anything else.
- Power off your smartphone and wait while the switch off process is completed.
- Then, reboot download mode on your handset and afterwards connect your phone with your computer via USB cable.
- Run LG UP on your computer. From the flashing program click on Upgrade.
- Load the KDZ firmware file from your desktop.
- In the end click on the Start button and wait while the flashing process is automatically completed.
- Your smartphone will reboot in the end. Wait while this first boot is initiated and completed.
- That should be all; the new Android firmware should now run on your LG V30.
How to Install a custom ROM on LG V30
If you want to spice things up you should tweak the Android OS that powers your LG V30. And the best way in which you can customize, optimize and personalize everything is by replacing the stock Android OS with a custom ROM firmware.
A custom ROM is a free aftermarket distribution of official Android system. It is a ported firmware based on the official release and pre-loaded with extra features which cannot be found on the regular Android system. These extra features will add new functionalities on your LG V30 and you will then be able to receive more power, enjoy an improved battery life and so much more – in most situations a custom ROM will run better and faster than the stock Android OS.
Updating your LG V30 with a custom ROM is possible only if your smartphone is rooted and installed with a custom recovery image – with root ensured you will unlock and prepare the Android core system for the custom update operation, while the custom recovery image will be used on the actual flashing procedure. Our personal recommendation is to use TWRP recovery in order to ease your work.
This is going to be an unofficial update operation since an unofficial update firmware will be installed. So, the warranty of your LG V30 will get void while completing the steps explained below. As already mentioned, the warranty can be restored only if you choose to go back to stock – that can be done by using the previous section of this tutorial or by flashing a Nandroid backup package (by the way, a good idea will be to make a Nandroid backup before resuming anything else – that process will save the current Android OS that runs on your smartphone).
A general backup is also required – a hard reset must be applied because else the new ROM cannot run properly. Thus, if you want to protect your files you should first save everything – you can sync your data with your Google account, you can use backup and restore apps from Google Play or you can use built-in cloud storage platforms that are already running on your handset.
A computer is required. Moreover, you still need to charge your LG V30 before starting the flashing process if the power left is lower than 50%. Additionally, as already explained during the last section of this guide, you need to gain Developer rights on your phone and you then have to check the USB Debugging field. Of course, make sure you choose a fully stable custom ROM as otherwise you will end up in experiencing different malfunctions and you will most likely have to go back to stock.
- So, download the custom ROM that you want to flash on your LG V30 – you can use the xda-developers platform in that respect.
- Optional: if required also download compatible Google Apps – if Google Apps aren’t included in the update package it must be flashed separately.
- Save these two files on desktop.
- Power off your phone and wait a few seconds until the power off is completed.
- Afterwards, reboot recovery mode on your Android device.
- From recovery you need to wipe everything; so you have to make a hard reset and to clear app data cache – that can be done by selecting “wipe data factory reset”, “wipe cache partition” and “wipe dalvik cache”.
- Return to main menu of recovery and select ‘reboot system now’.
- Connect your phone with your computer via USB cable and transfer the downloaded files from desktop to your device.
- Remove the USB cable – the computer is no longer required.
- Enter recovery mode again on your LG V30.
- From recovery tap on Install and load the custom ROM package; then swipe in order to start the flashing process.
- Optional: when done, repeat the last step and install Google Apps.
- In the end, from main menu of recovery choose ‘reboot system now’.
Good job. Now you should know everything about how to update the LG V30. You can therefore smartly flash OTAs, apply the full firmware file if that’s required and even test new custom ROM platforms such as Lineage OS, AOKP or ParanoidAndroid.
