In conclusion, the Amazon Fire HD 8 (10th Gen) is a "diamond in the rough" that truly shines only when liberated from Fire OS. The process of finding and installing a verified custom ROM is a technical challenge that rewards the user with a versatile, high-performing Android tablet. While it requires a leap of faith into the world of exploits and command-line interfaces, the result is a device that belongs entirely to the user, free from the ecosystem walls built by Amazon.

Verification warning: The amonet procedure is low-level and irreversible if failed. A wrong step can hard-brick the tablet (no charging LED, no ADB, no recovery). Verified unbrick methods exist but require disassembly and USB-UART debugging.

9/10. The only penalty is the Netflix resolution.
