Elephone S7 is maybe the perfect mix between high-end specs, premium look and affordable price tag available on the market. Unfortunately, its built-in Android OS isn’t offering the best experience that you can get, but that can be now improved with the help of a new custom ROM firmware based on Android 7.1.2 Nougat. I’m talking about Lineage OS 14.1 custom software, which can be now successfully installed and booted on your own Elephone S7.
Lineage OS 14.1 is the CyanogenMod iteration and is based on the Android 7.1.2 Nougat firmware. It is a custom ROM developed by third party devs – in our case, for the Elephone S7, we are talking about those of xda-developers (we must thank them for this new update opportunity as we are here only to detail the flashing process that must be followed). So, Lineage OS isn’t released by your OEM and it cannot be associated with Google – that’s why, the update operation is an unofficial one.
So, Lineage OS 14.1 can be only manually installed on your Elephone S7. And since you are going to flash an unofficial port of stock Android 7.1.2 Nougat OS, you are also going to lose your phone’s warranty – that’s happening when you try to tweak your device. Anyway, don’t worry as the warranty can be anytime restored by reinstalling the stock Android firmware.
As for the actual update package you need to know that it is still under development stage. Thus, in a few words, you might still experience minor issues from time to time. However, the Lineage OS 14.1 custom ROM can be used on the Elephone S7 on a daily basis – and the devs are working as we speak in providing a fully stable Android 7.1.2 Nougat firmware for your smartphone, so from this point of view you have nothing to worry about.
So, saving the stock Android firmware that already runs on your Elephone S7 might be a good idea – in that way you can make sure that you can choose to go back to stock if the new update will not run as you expected. Well, securing the stock Android software can be done if you complete a Nandroid backup – afterwards, the Nandroid backup can be flashed through recovery and you can restore the stock Android OS without following another complex installation process.
For the update operation that’s explained in this tutorial you will need to use a rooted Elephone S7 – the Lineage OS 14.1 can be installed only on an unlocked system because the update package will have to access, modify and customize built-in settings, features and programs. Moreover, a custom recovery image will be required as the Android 7.1.2 firmware can be flashed only through a custom recovery environment – I recommend you to use the latest version of CWM or TWRP recovery in order to make things work from your first attempt.
A new custom ROM can run only if you first wipe everything from your smartphone. A full wipe is therefore essential for this operation which means that you can lose important files – so a backup shouldn’t be optional; otherwise you will lose your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and more. On your Elephone S7 you can use built-in cloud storage platforms or you can just choose to sync your files with your Google Account. Another way in which you can initiate a backup is by using dedicated apps from Google Play (in that case make sure you download only already tested apps).
On your phone you will have to perform a few optimizations: from Menu – > Settings you need to go to About Phone and tap repeatedly on Built Number – after 7, or 10 taps you will receive the ‘you are a developer’ message; next, access Developer Options from Menu – > Settings and check the USB Debugging field.
You need to use a computer for downloading the required files which are offered below. If the download process cannot be completed you might have to temporarily deactivate the security programs that are running on your PC.
Verify the power that’s left on your Elephone S7 as if the power that’s left is lower than 50% you should charge it first. Low power might lead to a soft bricked smartphone as if the Android OS will get turned off in the middle of the update process different malfunctions might be caused. So, plug in the charger if that’s required.
The Lineage OS 14.1 based on Android 7.1.2 Nougat firmware that’s offered below is compatible only with the Elephone S7 so make sure you are not using the steps from below if you use a similar or a different handset.
