FAQs
Q1. How can I be absolutely sure I have the 3G version?
The 3G version has much lower specs: it only has 512MB of RAM, 4GB of storage, and runs the very old Android 4.2.2 Jelly Bean. The 4G model has 1GB of RAM, 8GB of storage, and runs Android 4.4.4 KitKat. Checking your `Settings > About phone` is the best way to confirm.
Q2. Can this phone run any apps at all?
With 512MB of RAM and Android 4.2.2, this phone is functionally obsolete. It cannot run any modern version of WhatsApp, Facebook, YouTube, or any other popular app. This firmware restores the phone to its original state, which is suitable only for basic calling and SMS.
Device-Specific Troubleshooting
- “Insufficient Storage” is a Critical Issue: The 4GB of internal storage is almost entirely consumed by the operating system. A microSD card is mandatory, but most apps cannot be moved to it on this version of Android. Expect to have almost no usable space after flashing.
- SP Flash Tool Doesn’t Detect the Phone: This is a driver issue. Reinstall the VCOM drivers (disabling driver signature enforcement in Windows). The removable battery is key: remove it, click “Download” in SP Flash Tool, then connect the phone without the battery.
- “Invalid IMEI” after Flashing: This critical error occurs if you use the “Format All + Download” option. To prevent this, always use the “Download Only” mode.
