How to Unroot Android Completely

Time to remove root? Maybe for warranty service, selling your phone, or just want a fresh start.

Here's how to cleanly unroot any Android device.

---

Why Unroot?

Common reasons:

• Warranty claim requires stock device
• Selling phone to someone unfamiliar with root
• Banking apps giving issues (quicker than configuring hiding)
• System stability problems
• Want completely fresh start
• New job requires stock phone

Unroot Methods

---

Method 1: Unroot via Magisk App

Easiest method if Magisk is working properly.

Steps

1. Open Magisk app
2. Tap "Uninstall Magisk" (at bottom)
3. Select "Complete Uninstall"
4. Wait for process
5. Phone reboots automatically
6. Magisk is gone!

What This Does

• Removes Magisk from boot partition
• Deletes Magisk app
• Removes all modules
• Removes root access

What This Doesn't Do

• Doesn't remove custom ROM (stays)
• Doesn't remove custom recovery (stays)
• Doesn't lock bootloader
• Doesn't restore stock firmware

Method 2: Flash Stock Boot Image

If Magisk uninstall doesn't work or want extra certainty.

Get Stock Boot Image

From Firmware Package:

1. Download stock firmware for your device
2. Extract boot.img from package

From Payload.bin (Modern Android):

1. Extract payload.bin from OTA
2. Use payload_dumper to extract boot.img
3. Save boot.img

Flash Stock Boot

Via Fastboot:

adb reboot bootloader
fastboot flash boot stock_boot.img
fastboot reboot

Via TWRP:

1. Copy boot.img to phone
2. TWRP → Install → Install Image
3. Select boot.img
4. Select Boot partition
5. Flash
6. Reboot

After Flashing

Root is now removed. Magisk app will show "N/A" status.

Method 3: Full Stock Restore

For complete stock return (warranty, selling).

Samsung

Using Odin:

1. Download stock firmware from SamMobile
2. Boot to Download Mode
3. Flash all partitions in Odin:
   - BL
   - AP  
   - CP
   - CSC
4. Wait for PASS
5. Device is fully stock

Xiaomi

Using MiFlash:

1. Download Fastboot ROM from MIUI
2. Boot to Fastboot mode
3. Flash with MiFlash (clean all)
4. Wait for completion
5. Device is stock

Pixel

Using Factory Images:

# Download factory image
# Extract and run
./flash-all.sh
# Device returns to stock

OnePlus

Using MSM Tool:

1. Download MSM Download Tool
2. Boot to EDL mode
3. Run MSM Tool
4. Wait for completion
5. Device is stock + bootloader re-locked

---

Removing Custom Recovery

If you also want stock recovery:

Flash Stock Recovery

adb reboot bootloader
fastboot flash recovery stock_recovery.img
fastboot reboot

Or Let Stock Replace It

Stock Android often replaces custom recovery automatically on boot (if not rooted).

---

Re-Lock Bootloader

⚠️ WARNING: Only do this on COMPLETELY STOCK device.

Re-locking with custom software = potential brick!

Verify Stock First

# Check if all partitions are stock
# Only proceed if you flashed full stock firmware

Re-Lock Commands

Most Devices:

adb reboot bootloader
fastboot flashing lock
# Confirm on device

Samsung:

Settings → Developer Options → OEM Unlock → Disable
-OR-
Download mode → Volume Up to re-lock

What Re-Locking Does

• Wipes all data (factory reset)
• Restores verified boot
• Returns boot status to locked
• Warranty perspective: looks unmodified

Knox Warning (Samsung)

Re-locking bootloader does NOT restore Knox:

• If Knox was tripped (0x1), it stays tripped
• This is permanent hardware fuse
• Samsung can still see device was modified

---

Verify Unroot Success

Check Root Status

Root Checker app:

Download "Root Checker"
Run check
Should show "Root not properly installed"

Check SafetyNet

YASNAC or Play Integrity Checker:

Run attestation test
Should pass BASIC and DEVICE integrity

Check Other Verification

Banking apps should work
Google Pay should work
Netflix should be downloadable from Play Store

What About KernelSU?

If you used KernelSU instead of Magisk:

Uninstall KernelSU

1. Open KernelSU app
2. Disable root for all apps
3. Flash stock kernel or boot image
4. Uninstall KernelSU app

---

What About LSPosed?

If you had LSPosed installed:

Full Removal

1. Uninstall LSPosed app
2. Remove LSPosed module from Magisk
3. Reboot
4. Then proceed with Magisk uninstall

---

Troubleshooting

Magisk Uninstall Fails

Solution: Flash stock boot image manually

Still Failing SafetyNet After Unroot

Possible causes:

• Bootloader still unlocked (triggers some checks)
• Data partition has remnants
• Custom ROM detected

Solutions:

• Re-lock bootloader (if safe to do so)
• Factory reset
• Flash full stock firmware

Apps Still Say "Rooted Device"

Some apps cache root detection:

1. Clear app data
2. Reinstall app
3. Fresh login

---

Going Back to Root Later

If you unroot temporarily (warranty) and want root back later:

Keep These Saved

• Your working Magisk-patched boot.img
• TWRP recovery image
• ROM + GApps you were using

Re-Root Process

1. Unlock bootloader (wipes data)
2. Flash TWRP
3. Flash ROM
4. Flash Magisk
5. Restore setup from backup

---

Checklist for Complete Clean Phone

Full Stock Return:
[ ] Flash complete stock firmware
[ ] Remove custom recovery
[ ] Factory reset
[ ] Re-lock bootloader (if safe)
[ ] Verify SafetyNet passes

---

Summary

Quick unroot: Magisk → Uninstall → Complete

Full stock:
1. Flash stock firmware via brand tool
