How to Fix Magisk "Installed: N/A" (Root Not Detected)

When the Magisk App opens and displays "Installed: N/A" on the main status card, the Magisk root daemon (magiskd) failed to initialize during boot. Follow this guide to diagnose and resolve the 4 primary root causes.

The 4 Primary Root Causes of "Installed: N/A"

Cause 1 (Most Common on Android 13+): You patched boot.img instead of init_boot.img. Under GKI 2.0, boot.img contains only the raw Linux kernel without a ramdisk.
Cause 2 (A/B Slot Mismatch): You flashed the patched image into Slot A (e.g. init_boot_a), but the device booted from active Slot B.
Cause 3 (Hidden App Stub Desync): The Magisk App was repackaged with a random package name, but lost permissions to access the UNIX domain socket.
Cause 4 (Samsung VaultKeeper Lock): Samsung Knox reset the bootloader state to Locked (L) upon first boot.

Step-by-Step Resolutions

Fix 1: Target the Correct Partition (`init_boot.img`)

If your device launched with Android 13, 14, 15, or 16 (Pixel 7/8/9, OnePlus 11/12, Xiaomi 13/14):

Fastboot init_boot Flashing

# Extract stock init_boot.img from firmware, patch in Magisk App, and flash: $adb reboot bootloader $fastboot flash init_boot magisk_patched.img $fastboot reboot

Fix 2: Resolve A/B Slot Confusion (Flash Both Slots)

If your device uses seamless A/B partitions, flash the patched image explicitly into both slot targets:

Dual Slot Flashing Commands

# Flash both A and B slots simultaneously: $fastboot flash init_boot_a magisk_patched.img $fastboot flash init_boot_b magisk_patched.img $fastboot reboot

Fix 3: Reinstall Unhidden Official Magisk APK

If the Magisk App was hidden/repackaged and lost socket connectivity:

Download the official Magisk-v30.7.apk.
Install it directly over the existing installation using: adb install -r Magisk-v30.7.apk.
Open the freshly installed Magisk app and grant superuser permissions if prompted.

Deep Triage: Understanding Partition Ramdisk Detection

When the Magisk App shows "Installed: N/A", it means the application attempted to communicate with the magiskd Unix domain socket and received no response. This occurs for one of four specific technical reasons:

Ramdisk Partition Relocation (Android 13+): On devices running Linux kernel 5.10 or higher with GKI 2.0 architecture, early boot ramdisk logic was moved from boot to init_boot. Flashing patched images to boot leaves the actual ramdisk unaltered.
OEM Verified Boot Reversion: On certain OEM skins (notably Xiaomi HyperOS and Samsung One UI), the bootloader or stock recovery automatically restores the backup stock boot image upon detecting signature changes if AVB 2.0 (Android Verified Boot) is not properly handled.
Seamless Slot Swapping: Following an OTA update, Android alternates from slot _a to _b. If Magisk was flashed only to the inactive slot, the system boots the unpatched stock slot.

Verify Active Boot Slot via Fastboot

# Query the active boot slot in fastboot: $fastboot getvar current-slot # Flash explicitly to active slot (e.g. slot a): $fastboot flash init_boot_a magisk_patched.img
