How to Unroot the Huawei U8180 Phone

Card No. 06·48770 · Updated · Standard formula, shown below

Unrooting the Huawei U8180 (also known as the Huawei Ascend Y100) restores the phone to its original factory state, removing root access and reinstalling the stock Android system. This guide walks you through the entire process, from backing up your data to verifying the unroot is complete. You’ll need a Windows PC, a USB cable, and the official Huawei HiSuite software or the Android SDK tools.

What You’ll Need

  • A Windows PC (Windows 7 or later)
  • A USB data cable that fits the U8180
  • Huawei HiSuite software (available from Huawei’s official support site)
  • Android SDK Platform Tools (for ADB and Fastboot commands) – optional but recommended
  • Backup of your personal data (contacts, photos, etc.)

Step-by-Step

  1. Back up your data. Unrooting will erase all data on the phone. Connect the phone to your PC, enable USB storage mode, and copy all important files (photos, videos, documents) to your computer. Also sync contacts and calendar to your Google account or export them to a .vcf file.
  2. Charge the phone. Ensure the battery is at least 50% charged to avoid the phone powering off during the process.
  3. Enable USB debugging. On the phone, go to Settings > Developer options > tick USB debugging. If you don’t see Developer options, go to Settings > About phone and tap Build number seven times to enable them.
  4. Install HiSuite on your PC. Download and install the latest version of Huawei HiSuite from the official Huawei website. Launch the software after installation.
  5. Connect the phone to the PC. Use the USB cable to connect the U8180 to your computer. HiSuite should detect it automatically. If prompted, allow USB debugging on the phone by tapping “OK” on the confirmation dialog.
  6. Download the stock firmware. In HiSuite, go to the Update or System Update section. If the phone is rooted, the software may show a “Repair” or “Restore” option. If not, you’ll need to download the official stock ROM for the U8180 from a trusted source (e.g., the Huawei support page). Look for a file with a .app or .dload extension.
  7. Start the unroot/restore process. In HiSuite, select the “System Recovery” or “Repair” function. Follow the on-screen instructions. The software will flash the stock ROM, which removes root and resets the phone to factory settings. This may take 5–10 minutes. Do not disconnect the phone during this time.
  8. Reboot the phone. Once the process completes, the phone will restart automatically. It may take longer than usual on the first boot. After it boots, you’ll see the Android setup wizard, indicating the phone is back to stock.
  9. Verify unroot. After setup, go to the Google Play Store and install a root checker app (e.g., “Root Checker”). Open the app and tap “Verify Root”. It should show that root access is not properly installed.

Common Mistakes

  • Not backing up data: Many users forget to back up, losing all personal files. Always copy important data before starting.
  • Using the wrong firmware: Installing a firmware meant for a different Huawei model can brick the phone. Only use firmware specifically for the U8180.
  • Disconnecting the USB cable during flashing: Interrupting the process can leave the phone in a non-bootable state. Keep the cable securely connected.
  • Ignoring battery level: If the phone dies mid-flash, it can cause a brick. Always ensure a sufficient charge.
  • Skipping USB debugging: Without USB debugging enabled, HiSuite may not recognize the device or the flashing may fail.

Tips

  • Use a USB port directly on the PC, not a USB hub, to avoid connection drops.
  • If HiSuite doesn’t offer a “Repair” option, try using the Android SDK’s fastboot command: boot the phone into fastboot mode (usually by holding Volume Down + Power), then run fastboot flash system system.img (if you have the stock system image). This is more advanced.
  • After unrooting, the phone may receive OTA updates again. This is a good sign that the stock ROM is correctly installed.
  • If you plan to root again later, note that the bootloader may be locked after unrooting, so you’ll need to unlock it again.

Troubleshooting

  • HiSuite doesn’t detect the phone: Try reinstalling the USB drivers. You can find them in the HiSuite installation folder or download from Huawei’s site. Also, try a different USB port or cable.
  • The phone is stuck in a boot loop: If the phone restarts repeatedly after unrooting, perform a factory reset from recovery mode. Turn off the phone, then press and hold Volume Up + Power until the recovery menu appears. Use the volume keys to select “wipe data/factory reset” and confirm with the power button.
  • Unroot fails with an error: Check that you have the correct firmware version. Some errors occur when the firmware is for a different region. Also, disable antivirus software on your PC temporarily, as it may interfere with the flashing process.
  • Phone is bricked (won’t turn on): Try entering recovery mode or fastboot mode. If you can access fastboot, you can flash a stock recovery image. If not, you may need to use a specialized tool like SP Flash Tool (for MediaTek-based phones) – the U8180 uses a Qualcomm chipset, so you might need QPST. This is advanced; consider seeking help from a professional.
  • Root checker still shows rooted: Some root files may remain. Try using a file manager to delete /system/app/Superuser.apk or /system/xbin/su if you can access them via ADB. Alternatively, re-run the unroot process.

Frequently Asked Questions

Will unrooting void my warranty?

Unrooting restores the phone to its original state, so it should not void the warranty. However, if the phone has been physically damaged or tampered with, the warranty may still be void.

Do I need to unlock the bootloader to unroot?

No, unrooting does not require unlocking the bootloader. In fact, the stock ROM will relock the bootloader if it was unlocked.

Will I lose my apps and data?

Yes, the unrooting process wipes the phone’s internal storage. That’s why backing up is essential.

Can I unroot without a PC?

No, the standard method requires a PC with HiSuite or ADB. Some root management apps (like SuperSU) offer a “Full unroot” option, but that only removes root, not the custom ROM. To return to stock, a PC is required.

How long does the unrooting process take?

Typically 5–10 minutes for the flashing process, plus additional time for the first boot (which can take up to 5 minutes).

Will unrooting remove custom recoveries like TWRP?

Yes, flashing the stock ROM will replace the custom recovery with the stock recovery.
