How to Flash a Custom ROM (Android 14) on Nokia 8

Unlocking the Bootloader

• 💡 Nokia 8 users can install custom ROMs like Android 14, significantly upgrading from the outdated Android 9.
• 📌 Before starting, ensure your phone is connected to Wi-Fi and note down your model and serial number from the 'About phone' section.
• 🔑 Enable Developer Options by tapping the build number seven times, then verify if the bootloader is locked or unlocked.
• 🛠️ To unlock, visit hardreset.info to download necessary tools like ADB and Fastboot, and install Nokia drivers.
• 💻 After restarting your PC, navigate to hikaricalyx.com to request an unlock file from HMD Nokia service using your serial number.
• 🔌 Power off your phone, then boot into Download Mode by holding volume down and connecting the USB cable.
• ✅ Follow the on-screen prompts on your computer to confirm the bootloader unlock, which will erase your phone's data.

Installing Custom Recovery and ROM

• 🚀 For model TA-1004, download the provided custom ROM and GApps links from the description.
• 💻 Open a command prompt in the custom ROM folder and flash the custom recovery image using fastboot flash boot boot.img.
• 📱 Reboot into recovery mode by holding the volume up button during startup.
• 📥 In recovery, select 'Apply update' then 'Apply from ADB', and sideload the custom ROM file (e.g., CRDroid) using adb sideload <filename>.
• 🌟 After the ROM installation, reboot back into recovery and sideload the GApps package (e.g., Nick GApps) using the same adb sideload command.

Setup and Troubleshooting

• 🔄 Once both sideloads are complete, select 'Reboot system now' to boot into Android 14.
• ✨ The first boot may take a while, showing the CRDroid animation.
• ⚠️ If you encounter issues, a factory data reset might be necessary, or you may need to repeat the flashing process.
• ✅ Upon successful setup, you'll have a fully functional Android 14 experience on your Nokia 8, distinct from the original Nokia UI.
