The Samsung Galaxy S2 Plus, an upgraded version of the original Galaxy S2, gained additional features and enhanced Samsung’s reputation. Released in 2013, the phone ran on Android 4.1.2 Jelly Bean during a time when smartphones were at this stage. However, we now find ourselves in 2017 with the 7th iteration of Android already released. If you’re still using a Galaxy S2 Plus running on Android 4.1.2 or 4.2.2, you’re essentially stuck in the past and not moving forward. The good news is that you can upgrade your aging Galaxy S2 Plus to the latest Android 7.1 Nougat. However, this requires flashing a custom ROM since it cannot be done through stock firmware.
The firmware we’re referring to is CyanogenMod 14.1, the most popular aftermarket version of Android. Despite CyanogenMod being discontinued, as long as you have the firmware files, you can still proceed with installing it. Take advantage of this opportunity before Lineage OS takes over, and enjoy the Nougat experience on your Galaxy S2 Plus. The ROM available offers flawless functionality for WiFi, Bluetooth, Calls, SMS, Mobile Data, Camera, Audio, and Video. It can serve as your everyday driver, meeting all your smartphone needs effortlessly. To flash this ROM, you just need a little confidence. The following guide provides a well-explained method with precautions outlined for the installation process. Follow the instructions to learn how to install Android 7.1 Nougat on Galaxy S2 Plus I9105/I9105P using CyanogenMod 14.1 Custom ROM.
Preventive Actions
- Caution: This ROM is only for Galaxy S2 Plus. Flashing it on any other device may lead to bricking. Verify your device’s model number under settings > About device.
- To prevent any power-related problems during the flashing process, make sure to charge your phone to at least 50%.
- To avoid encountering a Status 7 error, it is advised to install TWRP as the custom recovery on your Galaxy S2 Plus, rather than CWM.
- It is highly recommended to create a backup of all your important data, such as contacts, call logs, and text messages.
- Don’t overlook the importance of creating a Nandroid backup. This step is highly recommended as it allows you to revert to your previous system if anything goes wrong during the installation process.
- To prevent any potential EFS corruption in the future, it is strongly advised to back up your EFS partition.
- It is crucial to follow the instructions precisely and without any deviations.
DISCLAIMER: Flashing custom ROMs voids the device warranty and is not officially recommended. Please be aware that you are proceeding with this at your own risk. In the event of any issues, Samsung, nor the device manufacturers can be held responsible.
