If you want to tweak your Asus Zenfone 4 Selfie for improving general performance or if you just want to extend your Android access, you must replace the stock recovery software with a custom recovery image. So, as always, we are here to assist you. Thus, during the following guidelines we will discuss about installing TWRP recovery on your device, everything being detailed and explained especially for the new Zenfone 4 Selfie.
TWRP recovery is based on CWM recovery. Both are custom recovery images developed by third party devs and which can replace the stock recovery environment that is pre-loaded within the Android core system. As you might already know, through this environment you can access and then modify / optimize / personalize the Android OS that runs on your Asus Zenfone 4 Selfie. Anyway, with the stock recovery you can initiate only official operations such as making a hard reset, applying OTAs, or clearing app data cache.
Thus, the fun begins when a custom recovery image is used as in that case your Android access will be unlimited. So, your tweaking possibilities will be endless. In few words, after completing this step by step guide you will be able to unleash the full potential of your device – bump speeds, improve the battery life and change everything else. Of course, everything can be ensured through additional custom operations such as: gaining root access, flashing .zip files (such as custom ROMs updates, custom MODs and kernels), removing bloatware, adding root-only apps, make Nandroid backups, overclock CPU frequencies.
So, TWRP recovery will let you customize and optimize the Android OS. However, as outlined before, this is a third party software which isn’t offered by Asus. That’s why, the steps from below can be completed only if your Zenfone 4 Selfie runs on an unlocked bootloader – ensure this process first as otherwise you won’t manage to change anything.
Moreover, due to same aspects, the warranty might get lost. Unfortunately, you cannot change that – when applying unofficial operations the brand warranty gets void. The only way in which you can try to restore the warranty is by re-flashing the stock Android firmware situation during which you will manage to revoke all the tweaks: root access will be revoked, the stock recovery image reinstalled and the bloatware relocked.
As a precaution measure you should initiate a general backup. In this way you can protect your personal files – in rare situations your data might get corrupted or even wiped out during the TWRP recovery installation process. On your Asus Zenfone 4 Selfie the backup can be easily ensured as you can choose to use built-in cloud storage platforms, you can sync your files with your Google Account or you can just use compatible backup and restore apps from Google Play. Of course, the goal is to secure everything that means something for you such as contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, IMEI / NVRAM data, EFS folder and so on.
This is a manual flashing operation. So, a computer is required and your Zenfone 4 Selfie and its official USB cable must be there too. Since a connection between your devices will be implied, on your phone you have to check the USB Debugging option. This field can be accessed by going to Menu – > Settings – > Developer Options. If Developer Options isn’t there you first have 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.
On the computer that will be used you need to install the Asus Zenfone 4 Selfie drivers. Also, Android SDK must be installed as TWRP recovery can be added by executing dedicated adb commands. Thus, before doing anything else learn how to install Android SDK on Windows or how to set up ADB on MAC OS X / Linux.
Your smartphone must run on more than 50% power. Otherwise the Android system can get turned off right while you try to flash TWRP recovery. If a sudden shut down occurs your Asus Zenfone 4 Selfie can get bricked – various soft related problems can be caused within the Android core system. That’s why you should be careful and, of course, that’s why you should plug in the charger first if that’s required.
