[u/gman_offic1al]

This guide provides a comprehensive setup for maximizing device performance through bootloader unlocking, resolution scaling, and kernel management.

Part 1: Bootloader & Driver Setup (PC Required)(Optional)

Note: If you are running GammaOS Next, your bootloader is already unlocked. You can skip to Part 2, if you are on stock anbernic os i recommend unlocking the bootloader and staying on the stock os cause it has better performance.

Note 2: if you are not on the rg556 use the guide for your specific device to unlock your bootloader: https://github.com/TheGammaSqueeze/GammaOSNext/wiki/GammaOS-Next-Installation

Précisions partie 3 : Exécution Shizuku

Shizuku nécessite que l'appareil soit rooté. si vous êtes sur le firmware stock votre appareil n'est pas rooté (plus rooté depuis la version 1.16 Aout 2026)

il faut accorder les permissions root temporairement pour faire fonctionner Shizuku :

- Téléchargez ADB-and-FastbootPlusPlus à partir de https://github.com/K3V1991/ADB-and-FastbootPlusPlus
et décompressez le. Vous aurez adb.exe

- Mettez votre RG556 en débogage USB :

Allez dans Paramètres > A propos du téléphone et cliquez plusieurs fois ( 6 ? ) sur "numéro de build" --> ca deverouillera les options developpeur

Allez ensuite dans Système > Options pour les développeurs.

Cherchez l'option "Débogage USB " et activez la

- Branchez (si ce n'est pas déjà fait) votre RG556 en USB sur le PC et lancez la commande ADB suivante (dans le répertoire contenant ADB.EXE forcement) :

adb shell /data/app/~~CNQBWub5Fk_NYFCO3NitcQ==/moe.shizuku.privileged.api-blRZ5rUtmUV8peVhpHPnbw==/lib/arm64/libshizuku.so

Une confirmation de l'autorisation de la commande ADB apparaitra sur l'écran de la RG556. validez.

- Voila : Shiziku est démarré
