Root Walton Primo E2: Step-by-Step Guide

Rooting your Walton Primo E2 gives you administrator-level access to the Android operating system, allowing you to remove pre-installed bloatware, install custom ROMs, use root-only apps, and gain deeper control over system settings. This guide walks you through the entire process safely, from unlocking the bootloader to installing Magisk. Before you begin, back up all important data, as rooting will wipe your device, and ensure your phone has at least 70% battery to avoid interruptions.

What You’ll Need

• A Windows PC (Windows 7 or later)
• USB data cable for your Primo E2
• Walton Primo E2 with at least 70% battery
• Backup of your personal data (contacts, photos, etc.)
• Enable USB Debugging and OEM Unlock in Developer Options
• Download the following files:
  • Walton USB drivers (from official Walton support site)
  • SP Flash Tool (latest version)
  • Magisk APK (latest stable release)
  • Stock boot.img for Walton Primo E2 (extract from the official firmware)

Step-by-Step

1. Backup Your Data – Use the built-in backup feature or a third-party app to save contacts, messages, photos, and any other important files to your PC or cloud storage.
2. Enable Developer Options – Go to Settings > About Phone, then tap Build Number seven times until you see “You are now a developer!�
3. Enable USB Debugging and OEM Unlock – In Settings > Developer Options, toggle on USB Debugging and OEM Unlock. If OEM Unlock is missing, your device may not support it; you can still try the process, but it might fail.
4. Install USB Drivers – Install the Walton USB drivers on your PC. After installation, connect your Primo E2 via USB and ensure Windows recognizes it (check Device Manager for any yellow warnings).
5. Unlock the Bootloader – This step is critical and will wipe your device. Use SP Flash Tool’s “Formatâ€� option or run the command fastboot oem unlock from a command prompt (after booting your phone into fastboot mode by holding Volume Down + Power). Confirm the unlock on your phone screen.
6. Extract the Stock boot.img – Download the official firmware for your Primo E2 and extract the boot.img file. This is the stock kernel image that we will patch with Magisk.
7. Patch boot.img with Magisk – Install the Magisk APK on your phone. Open the Magisk app, tap “Installâ€� next to “Magiskâ€�, then select “Select and Patch a Fileâ€�. Choose the boot.img file you extracted. The patched file will be saved in your Download folder as magisk_patched.img.
8. Copy the Patched Image to PC – Transfer the magisk_patched.img file to your PC via USB.
9. Flash the Patched Image – Use SP Flash Tool to flash the patched image to the boot partition. In SP Flash Tool, load the scatter file from your firmware folder, then select only the “boot� partition and point it to the patched image. Click “Download� and connect your powered-off phone (with battery in) to the PC. The flashing process will start automatically.
10. Reboot and Verify – Once flashing is complete, disconnect the phone and power it on. After boot, open the Magisk app – it should show “Magisk is installedâ€� and the version number. To verify root, install a root checker app from the Play Store or use a terminal emulator and type su – a prompt should appear asking for permission.

Common Mistakes

• Skipping the bootloader unlock – If you don’t unlock the bootloader, flashing will likely fail or cause a boot loop.
• Using the wrong boot.img – Ensure you use the exact boot.img from the firmware version installed on your phone. Using a mismatched image can cause instability.
• Not enabling USB Debugging – SP Flash Tool may not detect your device without it.
• Interrupting the flash – Do not unplug the USB cable during flashing. A sudden disconnect can brick your device.
• Forgetting to back up – The bootloader unlock wipes all data. If you skip the backup, you lose everything.

Tips

• Use the original USB cable that came with the phone, as third-party cables may have data transfer issues.
• Keep your phone charged above 70% to avoid shutdown during the process.
• If you’re not comfortable with SP Flash Tool, you can try using the fastboot method: boot into fastboot mode and run fastboot flash boot magisk_patched.img.
• After rooting, install a root manager like Magisk (which is already installed) to control which apps get root access.
• Always keep a backup of your stock boot.img so you can unroot later by reflashing it.

Troubleshooting

If something goes wrong, here are common issues and fixes:

• SP Flash Tool doesn’t detect the phone – Reinstall the USB drivers, try a different USB port (preferably USB 2.0), and ensure the phone is powered off before connecting. Also, remove the battery and reinsert it before trying again.
• Boot loop after flashing – This usually means the patched image is incompatible. Re-download the stock firmware, extract a fresh boot.img, and re-patch it with Magisk. Then flash again. If it still fails, restore your stock boot.img to get the phone working.
• Magisk app says “Magisk is not installedâ€� – The patched image may not have been flashed correctly. Re-do the flashing step, ensuring you select the correct partition and that the flash completes without errors.
• Phone stuck on logo – Boot into recovery mode (Volume Up + Power) and perform a factory reset. This will wipe data but should restore the system to a bootable state.
• Root checker says “not rootedâ€� – Open Magisk, tap “Installâ€� and choose “Direct Installâ€� (if available) to reinstall the root files, then reboot.

Frequently Asked Questions

Will rooting void my warranty?

Yes, in most cases rooting voids the manufacturer’s warranty. You can usually restore the stock firmware to regain warranty, but it’s not guaranteed.

Can I unroot my Walton Primo E2?

Yes, you can unroot by flashing the original stock boot.img back using SP Flash Tool or fastboot. This will remove Magisk and restore the device to its unrooted state.

Will I still receive OTA updates after rooting?

Generally, OTA updates will fail because the system partition is modified. You can still manually install updates by downloading the firmware and flashing it, but you’ll need to re-root afterward.

Is rooting safe for my phone?

Rooting itself is safe if done correctly. The risk lies in flashing the wrong files or interrupting the process, which can brick the device. Follow the steps carefully.

Do I need a custom recovery like TWRP?

No, this method uses SP Flash Tool and Magisk to patch the boot image, so a custom recovery is not required. However, TWRP can be helpful for backups and installing custom ROMs.

What if my phone is already bootloader locked?

You need to unlock the bootloader first. If the OEM Unlock option is not available, your device may not support unlocking, and you cannot proceed with this method.
