5. Summary: Is it Worth it in 2024+?
The Huawei Y9 Prime is a victim of geopolitics and planned obsolescence. But the custom ROM community refuses to let this unique pop-up camera phone die.
Bootloader: Huawei stopped providing bootloader unlock codes in 2018. To install any custom ROM, you’ll need an unlocked bootloader (paid services or exploit-based methods may exist, but proceed at your own risk).
Model Check: This applies to Huawei Y9 Prime (2019) – not the Y9s or newer models.
Backup Everything: Unlocking wipes all data.
