Before You Begin ⚙️
- 💾 Backup All Data: Flashing (especially via fastboot/QFIL) will wipe user data.
- 🔋 Charge to 60%+ Battery: Let your phone stay on safely throughout the process.
- 💻 Windows PC is Required for Fastboot/QFIL; for OTA Sideload, PC or SD card method works.
- 🔑 Unlock Bootloader: Only needed for Fastboot ROM; unlocking wipes internal storage.
- 🌐 Select Region Carefully: Using the wrong regional firmware may break LTE, fingerprint, or camera.
📱 Quick Flashing Guides
Method 1: Official Recovery/OTA ZIP (Recommended for Touch-Upgrades & Stock Recovery Users)
- Download the matching firmware ZIP, e.g.
NX551J_Z69_EN_TSXPR17D11L111.zipor other regional file above. - Copy the ZIP to root of your phone (or SD card), or use Windows “adb sideload” command for PC install.

Frequently Asked Questions (FAQs)
- Q1. Which regional firmware should I use for my Nubia M2 NX551J?
- The best choice is always the original region to match your phone’s hardware version. Using the global ROM on an Indian or Indonesian device may cause issues with VoLTE, fingerprint, or camera apps due to regional configuration differences.
- Q2. I’m stuck in a bootloop or hard brick—what is the safest recovery method?
- For soft-bricked phones (logo stuck but recovery works), use the latest regional OTA/Recovery ZIP. If hard-bricked and recovery fails, use QFIL/Fastboot unbrick package. Always back up before flashing, as data loss is likely.
- Q3. Why is my fingerprint sensor/camera/LTE not working after flashing?
- This is usually caused by using firmware from another region or the wrong tool (e.g., flashing a Chinese ROM to an EU device). Each NX551J firmware is tuned for specific hardware and bands. Restore to your original region or, for hardware failures, consult a service center for NV data restore.
- Q4. Do I need bootloader unlock for recovery/OTA updates?
- No—stock recovery updates do not require unlocking. Only fastboot or QFIL flashing requires the bootloader to be unlocked first. Unlocking wipes all personal data.
