How to Install the OTA Update Package
Before proceeding, ensure your phone’s battery is charged to at least 50% and back up all important data as a precaution.
Method 1: Local Update via Settings (Recommended)
- Download the Firmware: Download the Nubia_Z17…OTA.zip file to your computer and transfer it to your phone, or download it directly on your device.
- Place the File Correctly: Use a file manager app to move the downloaded ZIP file to the root directory of your phone’s internal storage (i.e., not inside any folder like “Download”).
- Navigate to System Update: Go to Settings > System update.
- Initiate Local Update: Tap the gear icon or the three-dots menu in the top-right corner and select Local update.
- Select the Package: The system should automatically find the ZIP file. Tap on it and confirm the installation by pressing Install Now.
- Complete the Update: The phone will reboot, install the update in recovery mode, and then boot back into the newly updated system.
Method 2: Installation via Stock Recovery
- Download and Place File: Follow steps 1 and 2 from the method above.
- Boot into Recovery Mode: Power off your Nubia Z17. Press and hold the Volume Up + Power buttons simultaneously. Release them when the Nubia logo appears to boot into recovery.
- Apply Update: Using the Volume keys to navigate and the Power key to select, choose Apply update from internal storage (or a similar phrase).
- Select the ZIP File: Navigate to the …OTA.zip file in your root directory and select it with the Power button to begin the installation.
- Reboot: Once the installation is complete, select Reboot system now from the main recovery menu.
FAQs
Q1. Will this update work on a Nubia Z17S or Z17 mini?
No. This firmware package is specifically for the standard Nubia Z17 (NX563J). Attempting to install it on a different model will result in a failed installation and could potentially brick the device.
Q2. I have a Chinese version of the Z17. Will this add Google Play Services?
No. Official OTA updates do not add or remove core system components like Google Mobile Services (GMS). If your phone did not come with the Play Store, this update will not install it. You would need to install GMS separately.
Q3. Why does the update fail with a “Signature verification failed” error?
This error occurs because the update package requires a 100% stock system to install. It will fail if you have rooted your device, installed a custom recovery (like TWRP), or modified any system files. You must be on official, unmodified software.
Q4. Will this update erase my personal data?
Standard OTA updates are designed to install over your existing data without wiping it. However, especially when performing a major version upgrade (e.g., to Android 9), unforeseen issues can occur. Backing up your important data beforehand is strongly recommended.
Troubleshooting (Nubia Z17)
- Update Fails to Install: The most common reasons are having a modified (rooted) system or a corrupted download. Re-download the file to ensure it’s intact. Also, be aware that some OTA updates are sequential and may require you to be on a specific prior version before they can be installed.
- Device Stuck on Nubia Logo Post-Update: The first boot after a major update can take up to 15-20 minutes. If it is still stuck, force reboot into recovery (Vol Up + Power) and select Wipe cache partition. This is a safe step that doesn’t delete user data. If the problem persists, a Wipe data/factory reset (which erases all data) will likely be necessary.
- Apps Crashing After Android 9 Update: A major OS jump can cause compatibility issues. Go to the Google Play Store and update all your installed applications. If an app continues to crash, try clearing its cache and data via Settings > Apps.
- “Local update” option is missing: Ensure the firmware .zip file is correctly placed in the main (root) directory of your internal storage, not inside any sub-folders.
