Install: Immediately flash Gapps .zip after the ROM (no reboot in between).

Conclusion: Is It Worth It?

Yes, absolutely—if you meet the criteria.

If your Fire HD 8 (10th Gen) is running Fire OS 7.3.2.8 or lower, and you have moderate technical skills (opening electronics, running terminal commands), installing a custom ROM transforms the device from an ad-riddled shopping cart into a respectable media and reading tablet.

However, if you rely on Amazon Prime Video for offline downloads (due to Widevine L1 DRM) or you hate hardware tinkering, stay on stock Fire OS. Debloat it using a Fire Toolbox instead.

For the rest of us, the ability to run LineageOS on an $80 tablet is a middle finger to planned obsolescence. The Fire HD 8 10th Gen isn't a flagship, but with a custom ROM, it becomes yours.
