Update LG Optimus One with CM11 Android 4.4.2 KK Custom ROM Firmware

Install CM 11 Nightly ROM for Samsung Galaxy devices

CM11 is the best custom ROM based on Android 4.4 KitKat OS that can be installed on almost all the Android based devices out there. After we have showed you how to flash this firmware on numerous smartphones and tablets, now we should head our attention towards the LG Optimus One P500 users as during the guidelines from below we will be checking on how to update this smartphone to Android 4.4.2 software by flashing the latest CM 11 custom ROM platform. So if you want to improve the performances of your phone and test the latest Android OS, then you have to complete our dedicated step by step guide for applying the CM11 firmware on your LG Optimus One.

Why to choose a custom ROM? Well, first of all there won’t be any Android 4.4.2 OTA update released for your LG Optimus One. So, if you want to test the KitKat firmware on your phone you will have to install a custom update. Then, with a custom ROM you can enjoy features that cannot be found on the default Android platform. These features, apps and capabilities can then be used for improving the performances (gain more power, improve the speeds and the battery life and more) and for customizing and optimizing your Android based device.

But that’s not all. CM11 is one of the best custom ROMs developed for Android smartphones and tablets. The software is stable and runs smoothly on the LG Optimus One, while on top of all Android 4.4.2 will be installed. CM 11, being an unofficial Android OS, will be coming with its own looks and features, so don’t expect to receive the stock or default Android 4.4 software. Anyway, in a few words, with CM11 installed, your LG Optimus One will become your new playground as you will be able to tweak and personalize your Android device in a minute.

Of course, CM11 is developed by third party devs, so this tutorial has nothing to do with LG or with Google. This is not an official update since CM 11 is actually a free aftermarket distribution of Android 4.4.2 system that can now be installed on your Optimus One. Because of that, this tutorial should be considered complex and risky – it is also unofficial (CM11 can be installed only manually and only after preparing your device – see the guidelines from below).

The first thing to do when deciding to install a custom ROM, like CM11, is to root your Android device. So gain root access on your LG Optimus One. With root you will unchain the internal system of your phone by removing the factory and default restrictions that are installed. After gaining root access you should also install a custom recovery image like CWM or TWRP recovery. The custom recovery can be flashed only on a rooted system and is used of the update operation – the Android 4.4.2 software file will be flashed from the Optimus One SD card.

When completing the up mentioned operations you will also lose the warranty of your phone. All these procedures aren’t official so the warranty will get void. For restoring the same you will have to revoke the root access; you can do so once you downgrade your Optimus One to stock Android OS – of course then the CM 11 firmware will be replaced with the stock Android system, while root access will be revoked and the bootloader relocked.

A backup should also be completed before going any further. The system of your phone must be wiped out or else the CM11 will not run properly on your LG Optimus One. Because of that you can lose everything that’s saved on the internal storage memory of your device – I am talking about text messages, contacts, call logs, market apps and so on. Therefore use suitable backup and restore apps from Google Play and save everything you might need afterwards. Also, use the recovery image for saving the current ROM – do a Nandroid backup.

Those were the essential pre requisites; now, before heading to the proper update operation you need to take care of the general pre requisites. So check the list from below and apply the tasks described there.

  • You need to use your phone, its USB cable and you have to access or use a computer or notebook.
  • On the computer there shouldn’t be running any security program – these tools are usually interfering with the update operation.
  • So, temporarily deactivate the antivirus, antimalware and Firewall protection.
  • Since a connection between your device and computer must be established, first you have to enable USB debugging option on your phone – just go to “menu – settings – developer options”.
  • If your Optimus One gets turned off in the middle of the update operation, your handset might get bricked. Because of that you now need to check the battery status of your phone: if there is less than 50% power left you need to plug in the charger.
  • Also you should install CM11 by using this guide only if you own the LG Optimus One model number P500; the steps from below are compatible only with the mentioned smartphone – you can brick your device in case you mess things up.
