LG G2 might be an old Android based device but I know that there are still many users who are using it as their main driver or as a backup smartphone. Either way, if you do have the T-Mobile version of the LG G2 you might want to hear some good news: the Android Nougat firmware can be successfully flashed on your phone. No, unfortunately we are not talking about an official update but about a custom ROM in form of the new CyanogenMod iteration, the Lineage OS.
Based on the CM 14.1 firmware the new Lineage OS wants to improve the old CyanogeMod system in order to bring everything that’s new even to old devices such as the LG G2. The best is that with the help of this new custom ROM you can finally test and enjoy the Android Nougat experience on your own device.
And we are talking about a fully stable Android Nougat firmware as the update offered below is coming right from those of Lineage OS – so you are not dealing with a ported and modified version of the same software. However, a custom ROM is still involved which means that you will use a free aftermarket distribution of the stock Android Nougat software. Anyway, the platform is stable and will smoothly run on the T-Mobile LG G2 – you won’t experience any malfunctions and you will be able to use all the new features, apps and capabilities without any sort of problems.
Do note that flashing a custom ROM is not an official process. The warranty of your T-Mobile LG G2 will be lost if you will start to complete the steps from down below. Moreover, using a custom update comes with other risks which are mainly referring to your personal data, info, accounts and files – you see, the new ROM can replace the stock / official Android firmware only if a wipe is previously ensured.
Because of that I strongly recommend you to backup your T-Mobile LG G2. In order to succeed with your backup plan, you should use only tested methods such as: using built-in cloud storage platforms or syncing your data with your own Google Account. Alternatively you can use different backup and restore apps from Google Play – make sure you get only tested apps that can help you save personal data and system files.
Along with the classic backup you should also make a system backup. In that way you can save the Android system and restore it afterwards if, for example, the new Lineage OS is not running as expected on your T-Mobile LG G2. Therefore, consider in making a Nandroid backup before doing anything else.
As you will see if you will try to resume the steps from this tutorial, the Nougat firmware can be successfully installed only in certain conditions; here is what I am talking about:
- Root access must be established on your smartphone – without root the internal system of your phone will be locked, thus the new custom ROM won’t be able to modify, customize and optimize built-in settings, features, processes and apps. So, root your LG G2 before doing anything else.
- A custom recovery image must be installed on your phone – the Lineage OS, which is an unofficial port of the stock Android system, is offered in form of a .zip file, which can be flashed only by using a custom recovery software. In that respect I recommend you to use the latest version of CWM or TWRP recovery.
Other pre requisites related with this step by step guide:
- A computer is required as there you will save the files which are being offered below.
- Your phone and its USB cable as a connection between your devices is implied.
- On your LG G2 you have to gain developer rights – just tap several times (usually 7 times repeatedly) on Built Number until you see the ‘you are a developer’ message displayed.
- On your phone navigate towards “menu – settings – developer options”; from there select the USB Debugging feature.
- Check the battery life on your handset – if the power is lower than 60% plug in the charger.
- If you resume the steps from below regardless the battery level displayed on your phone, you will risk in dealing with software related problems – that can happen if your handset gets turned off right in the middle of the update operation.
- Resume the following lines only if you own the T-Mobile model of the LG G2. All the files from below (including the Lineage OS firmware package) are compatible only with this particular Android based device.
