Device-Specific Troubleshooting for Advan i6A
- CRITICAL – MediaTek vs. UNISOC Variant: The Advan i6A was made with two different chipsets. This firmware is for the MediaTek MT6737T version and requires SP Flash Tool. There is another version with a UNISOC SC9850 chipset that uses a
.cpbfile and the YGDP tool. Flashing the wrong firmware will fail and can brick your device. If your phone is working, use an app like CPU-Z to verify your chipset. - Restoring Lost Signal / Invalid IMEI: A common issue on MediaTek devices after a bad flash is the loss of the phone’s IMEI number, resulting in 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.
- 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.
FAQs
- Q1. How do I know if I have the MediaTek or UNISOC version of the Advan i6A?
- If your phone can turn on, install the app “CPU-Z” from the Play Store. It will show you the chipset manufacturer (MediaTek or Spreadtrum/UNISOC).

- Yes, the SP Flash Tool process will completely erase the phone’s internal storage, deleting all your personal data and restoring it to factory settings.
- Q4. What version of Android is this?
- This is the official stock firmware for Android 8.1.0 Oreo for the MediaTek version of the Advan i6A.
