Device-Specific Troubleshooting for Advan i5A
-
- Restoring Lost 4G Signal / Invalid IMEI: A common issue on MediaTek devices after incorrect flashing or rooting is the corruption of the NVRAM partition, which leads to a lost IMEI number and no network signal. Flashing this full stock ROM is the essential first step to fix this, as it restores the original modem files. If the IMEI is still null after flashing, you may need to use a separate tool to restore it.
- 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 from your PC, restart, and perform a fresh installation 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 encounter 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.
- Restoring Performance: Over time, even a 2GB RAM device can become slow due to accumulated app data and junk files. A clean flash with this stock ROM is the best way to restore the phone’s original speed and smooth operation.
FAQs
- Q1. My Advan i5A is dead after a failed software update. Will this fix it?
- Yes. This full firmware package is designed to overwrite the entire software system, including a corrupted bootloader or system partition, and will unbrick a phone with software-related issues.
