Getting Started: First Launch & Setup

This guide walks you through launching fparted for the first time, granting root permissions, understanding the interface, and safely navigating your storage hardware.

1. Prerequisites

Before using fparted, make sure your device satisfies these requirements: - Root Access: Rooted Android device running Magisk, KernelSU, or APatch with the standard root binary located at /system/bin/su. - Primary Android User: The app must run under the primary device profile (User 0). - Internal / External Storage: Built-in flash memory (UFS / eMMC), microSD card, or USB OTG storage drive.

2. Startup & Root Authorization

When you open fparted for the first time, it checks for /system/bin/su and tests for superuser authorization:

Cold Start ──► Root Gate Probe (/system/bin/su) ──► Superuser Grant Probe

Granting Root Permissions by Manager

  • Magisk typically displays an automatic Superuser Request popup dialog when fparted starts.
  • Tap Grant (or set to Always).
  • For KernelSU and its variants (KernelSU, KernelSU-Next, SukiSU, ReSukiSU, and APatch), untrusted apps do not trigger an automatic popup prompt by default due to kernel-level / SuperKey isolation.
  • Open your kernel root manager app (KernelSU, KernelSU-Next, SukiSU, ReSukiSU, or APatch).
  • Navigate to the Superuser / SuperUser tab.
  • Locate Partition Manager (vn.shadichy.parted) in the application list and toggle the switch to Grant Superuser.
  • Re-open or switch back to fparted.

[!WARNING] If root is denied or missing, fparted presents an immutable Exit dialog. If you are using KernelSU, APatch, or their variants, ensure you have enabled Superuser for Partition Manager in your manager app before launching.
