How to Flash Stock Firmware on MediaTek (MTK) Smartphones
FAQs
Q1. Can I install Google Play Store after flashing this firmware?
No. This is the official China ROM, which lacks the core Google framework. Manually installing Google Play Services on this old version of a Chinese ROM is very difficult and is not guaranteed to work correctly, if at all.
Q2. My 4000 mAh battery percentage drops suddenly. Will this fix it?
Yes, this is a classic sign of a battery software calibration issue. A full firmware flash with SP Flash Tool will reset the battery stats file. For best results after flashing, charge the phone to 100% uninterrupted, then use it until it fully discharges. This helps the new software re-learn the battery’s true capacity.
Q3. Will this firmware work on a non-Chinese version of the Blade A460?
It is not recommended. This firmware is for the Chinese model (Q519T) and has modem files configured for Chinese 4G networks (specifically China Mobile’s TD-LTE bands). Flashing it on a European or Latin American model could cause network connectivity issues (“No Service”).
Device-Specific Troubleshooting
- “Insufficient Storage” Errors: The 8GB of internal storage is the biggest bottleneck of this phone. It is essential to use a microSD card for all photos and media. Go to `Settings > Apps` to disable any pre-installed Chinese bloatware to free up precious system space for essential apps.
- Phone Boots up in Chinese: During the initial setup wizard, look for the language selection option, which is usually on the first screen and may be marked with a globe icon or the word `语言` (Yǔyán). You should be able to select English from the list.
- SP Flash Tool Doesn’t Detect the Phone: This is a driver issue. Reinstall the VCOM drivers (disabling driver signature enforcement in Windows first). The removable battery is your best tool: remove it, click “Download” in SP Flash Tool, then connect the phone without the battery. Once the red bar appears, you can re-insert it.
- “Invalid IMEI” after Flashing: This critical error occurs if you use the “Format All + Download” option in SP Flash Tool. It erases the phone’s unique identifier. To prevent this, always use the “Download Only” mode. Restoring a lost IMEI is a very complex process.
