YotaPhone2 Upgrade Guide: How to Update Your Device and Enjoy New Features Introduction YotaPhone2 is a unique smartphone that combines a full-color LCD touchscreen on one side and an electronic paper display on the other. It was released in 2014 with Android 4.4 KitKat and has been upgraded to Android Lollipop since then. However, many users still wonder how to upgrade it to the latest version of Android or how to install custom ROMs. In this guide, we will explain the steps to follow to get the most out of your YotaPhone2 and enjoy all the new features and improvements available. Part 1: Back Up Your Data Before starting the upgrade process, you should back up all your important data such as contacts, photos, videos, and apps. You can use the built-in backup feature provided by your YotaPhone2 or use third-party apps such as Helium, Titanium Backup, or Google Drive. To back up your data using the built-in feature, go to Settings > Backup & Reset > Back Up My Data and enable the option. You can also sync your Google account to backup your contacts, calendar, and other data. Part 2: Check for Updates YotaPhone2 receives OTA (Over-The-Air) updates from time to time, and you should always check for updates manually or enable automatic updates. To check for updates manually, go to Settings > About Phone > System Updates > Check for Update. If there is a new update available, download and install it using your Wi-Fi connection. The process may take a few minutes or more depending on your internet speed and the size of the update. Part 3: Install Custom ROMs If you want to install a custom ROM on your YotaPhone2, you should first unlock its bootloader and install a custom recovery such as TWRP (Team Win Recovery Project). You can find detailed instructions and downloads for your YotaPhone2 model on XDA Developers or similar forums. Once you have installed TWRP, you can download a custom ROM such as LineageOS, Resurrection Remix, or Paranoid Android and flash it using the recovery mode. Before flashing a custom ROM, you should also wipe your device's data, cache, and Dalvik cache to avoid conflicts. Part 4: Troubleshooting If you encounter any issues during the upgrade process or after installing a custom ROM, you can try some common troubleshooting steps such as clearing cache partition, factory resetting your device, or flashing the stock firmware. To clear cache partition, turn off your device and hold the Volume Up + Power buttons until the recovery mode appears. Then, select Wipe Cache Partition and confirm. To factory reset your device, go to Settings > Backup & Reset > Factory Data Reset and confirm. To flash the stock firmware, you should download the official firmware for your YotaPhone2 model and flash it using Odin or similar tools. Conclusion By following the above steps, you can upgrade your YotaPhone2 to the latest version of Android or install custom ROMs to experience new features and improvements. However, you should always be careful and backup your data before taking any action, as the upgrade process may cause data loss or damage your device if not done correctly.
