How to Flash Stock Firmware on MediaTek (MTK) Smartphones
FAQs
Q1. Is this the same as the standard Nubia M2?
No. The Nubia M2 Lite (MediaTek chipset) is a different model from the standard Nubia M2 (Qualcomm Snapdragon chipset). The firmware packages are not interchangeable and will brick the wrong device.
Q2. Can I use this firmware to update my phone to Android Nougat or Oreo?
No. This is an official stock firmware package for Android 6.0 Marshmallow. The Nubia M2 Lite did not receive widespread official updates to later Android versions.
Q3. What is a “scatter file”?
A scatter file (`.txt`) is a map of a MediaTek phone’s internal storage. It tells the SP Flash Tool the exact location and size of each partition (like system, boot, etc.), ensuring the firmware is written correctly.
Q4. The phone has a non-removable battery. How do I ensure it’s properly off for flashing?
To ensure the device is fully powered down, press and hold the Power button for about 10-15 seconds until you are sure it is off. Do not connect it to the charger before flashing.
Troubleshooting (Nubia M2 Lite)
- SP Flash Tool does not detect the phone: This is the most common issue. Reinstall the VCOM drivers, disable Driver Signature Enforcement in Windows if needed, restart your PC, and use a different USB port.
- Error: “PMT changed for the ROM”: This error occurs if the partition table on your phone doesn’t match the firmware. You can usually fix this by changing the flashing mode in SP Flash Tool from “Download Only” to “Firmware Upgrade”.
- Device is stuck in a bootloop after a successful flash: The first boot can be slow. If it’s still stuck after 15 minutes, boot into recovery mode (hold Volume Up + Power from off) and perform a “Wipe data/factory reset”.
- “Invalid IMEI” after flashing: This can happen if you accidentally use the “Format All + Download” option. To avoid this critical error, always use the “Download Only” mode.
