How to Unroot Samsung Galaxy Grand Prime Duos TV

This guide walks you through removing root access from your Samsung Galaxy Grand Prime Duos TV (SM-G530H). Unrooting restores the device to a stock, unmodified state, which is necessary for receiving official over-the-air (OTA) updates, using banking apps that block rooted devices, and for warranty service. Before starting, back up any important data, as the process will wipe the phone.

What You’ll Need

A Windows PC (for Odin flashing method) or just the phone itself (for the SuperSU unroot method).
The original USB cable that came with your phone.
Backup of your contacts, photos, and other personal files.
At least 50% battery charge on the phone.
Odin3 software (for the flashing method) – download from a reputable source.
The stock firmware file for the SM-G530H model – match your exact region/carrier variant.
Samsung USB drivers installed on your PC.

Step-by-Step

There are two reliable methods to unroot. Choose the one that matches how your device was rooted.

Method 1: Unroot via SuperSU (If you used SuperSU to root)

Open the SuperSU app on your phone.
Go to the Settings tab.
Scroll down and tap Full unroot.
Read the warning and tap Continue.
The app will remove root binaries and restore the stock boot image. The phone will reboot automatically.
After reboot, check for the SuperSU icon. If it’s gone, root is removed. If it remains, use Method 2.

Method 2: Flash Stock Firmware via Odin (Works for any root method)

Download the correct stock firmware for your exact SM-G530H variant (e.g., SM-G530HZKUXXU). Look for files ending in .tar.md5.
Extract the firmware zip file to a folder on your PC. You should see a file like AP_...tar.md5 or similar.
Extract the Odin3 zip file to another folder. Run Odin3.exe as administrator.
Power off your phone completely.
Boot the phone into Download Mode: Press and hold Volume Down + Home + Power buttons simultaneously for about 10 seconds. Press Volume Up when the warning screen appears.
Connect the phone to your PC via USB cable. Odin should show a blue or yellow box in the ID:COM section, indicating a successful connection.
In Odin, click the AP button (or PDA on older versions) and select the firmware file you extracted in step 2. Do not touch any other options.
Ensure F. Reset Time and Auto Reboot are checked. Leave Re-Partition unchecked.
Click the Start button in Odin.
Wait for the process to complete. A green PASS message will appear in Odin, and the phone will reboot automatically. This can take 5-10 minutes.
Unplug the phone. The first boot will take longer than usual – this is normal.

Common Mistakes

Using the wrong firmware file: Flashing firmware for a different region or carrier can cause boot loops or network issues. Verify your exact model number in Settings > About Phone and match the region code in the firmware filename.
Unplugging the phone during the Odin flash: This can permanently brick the device. Never disconnect the cable until Odin shows PASS or FAIL.
Not backing up data: Flashing stock firmware wipes all user data. If you skip the backup, you lose everything.
Forgetting to disable Samsung’s reactivation lock: If you have a Samsung account and the “Reactivate Lock” is enabled, the phone will ask for your Samsung credentials after flashing. Disable it in Settings > Accounts > Samsung > Reactivation Lock before starting.
Using a USB hub: Connect the phone directly to a USB port on your PC. Hubs can cause connection drops mid-flash.

Tips

After unrooting, check for a software update in Settings > About Phone > Software Update to confirm OTA updates work again.
If you plan to root again later, note that the bootloader on this model is often locked. Unlocking it voids warranty and may not be reversible.
Keep the stock firmware file saved on your PC for future use.
For the Odin method, use the original Samsung USB cable – third-party cables often fail to maintain a stable connection.
If you used a custom recovery (like TWRP), flashing stock firmware via Odin will also replace it with the stock recovery.

Troubleshooting

Odin doesn’t recognize the phone: Reinstall Samsung USB drivers, try a different USB port, or use a different cable. If the ID:COM box stays empty, the phone is not in Download Mode – reboot and try again.

Odin fails with “FAIL” message: This usually means the firmware file is corrupted or wrong. Re-download the firmware from another source and verify the checksum if possible. Try a different Odin version.

Phone stuck in boot loop: If the phone restarts repeatedly after flashing, you likely flashed the wrong firmware. Boot into Download Mode again and flash the correct firmware. If it still loops, perform a factory reset from Recovery Mode (Volume Up + Home + Power).

SuperSU “Full unroot” fails: Some ROMs block the unroot process. Use the Odin method instead. Alternatively, open SuperSU, go to Settings, and select “Cleanup” to remove leftover files before attempting again.

Phone boots but still shows root indicator: Some root apps leave files behind. After flashing stock firmware, the system partition is completely replaced, so this should not happen. If a root checker app still says rooted, you may have flashed a pre-rooted ROM – download the official stock firmware.

Phone asks for Samsung account password after boot: This is the Reactivation Lock. Enter the credentials of the Samsung account that was previously on the device. If you don’t remember them, you cannot bypass this – contact Samsung support with proof of purchase.

Frequently Asked Questions

Will unrooting delete my photos and apps? Yes, the Odin flashing method wipes the data partition. The SuperSU method usually preserves data, but it’s safer to back up regardless.

Is unrooting the same as factory reset? No. A factory reset only wipes user data. Unrooting removes system-level modifications (root binaries, custom recovery) and restores the original firmware.

Can I unroot without a PC? Yes, if you rooted with SuperSU, use the “Full unroot” option. For other root methods, a PC is required for the Odin method.

Will unrooting make my phone faster? Not necessarily. Performance is largely unaffected by root. However, unrooting may improve stability if a root app was causing conflicts.

Do I need to unroot before selling my phone? Yes. Unrooting restores the phone to factory condition, which is expected by most buyers and prevents them from inheriting security risks.

What if I can’t find the exact firmware file? Check XDA Developers forums or Samsung’s official firmware update tool (Smart Switch) which can restore the stock firmware via a PC. Smart Switch’s “Emergency software recovery” option often works even on rooted devices.
