Device-Specific Troubleshooting for Advan i55
- CRITICAL – Not for Advan i55D: The Advan i55 (MediaTek chip) and the newer Advan i55D (Spreadtrum chip) are different phones. This firmware is ONLY for the original i55 and will brick the i55D model.
- Restoring Lost 4G Signal / Invalid IMEI: A common issue on these 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.
- PC Not Detecting the Phone: This is 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, change the dropdown option in SP Flash Tool from “Download Only” to “Firmware Upgrade” and try flashing again.
