Device-Specific Troubleshooting for Advan G1
- Restoring Lost 4G Signal / Invalid IMEI: A common issue on MediaTek devices after a bad flash is the corruption of the NVRAM, leading to a lost IMEI number and no network signal. Flashing this full stock ROM is the essential first step to fix this by restoring the original modem files. If the IMEI is still null after flashing, a separate tool may be needed to repair it.
- Fixing Fingerprint Sensor Issues: If the fingerprint scanner on your Advan G1 has become unresponsive or is not detected by the system, a full firmware flash can often resolve the problem. This process restores the original drivers and software components for the sensor, fixing any software-related conflicts.
- PC Not Detecting the Phone: This is the most common problem and is always caused by a driver issue. Uninstall any other mobile phone drivers, restart your PC, and do a fresh install of the MediaTek VCOM drivers. The phone should only be connected after clicking “Download” in the tool.
- SP Flash Tool “PMT changed” Error: If you see this error, the partition layout on your phone is different from the firmware’s. To solve this, change the dropdown option in SP Flash Tool from “Download Only” to “Firmware Upgrade” and try flashing again.
