I needed a small device to control my Home Assistant Setup. So I opened the drawer with the old smartphones that we all have, and naturally, I found two Nokia 6.1 phones.
Since the last Android Version that Nokia supports is 10, I decided to install a custom ROM. Doing so, I ran into multiple problems. Sadly, you will also need to use Windows for that.
There are three to four steps we need to perform. First, we need to unlock the bootloader. Then, we need to flash a new recovery image. Third, we flash a custom ROM (I will use LineageOS 21). Lastly, we can install official Google apps like Google Play or YouTube if you want.
Disclaimer: Following this guide will WIPE ALL YOUR DATA. I can’t take any responsibility for any damage to your device. What worked for my two phones will likely work for you, but there is no guarantee. Some features will not work with an unlocked bootloader or a custom ROM, such as paying with Google Wallet or using ID Austria.
