How to Flash Stock Firmware
To restore the software on your Advan i45, you will use the SP Flash Tool on a PC. First, ensure the MediaTek VCOM drivers are properly installed. Launch the tool, load the MT6735M_Android_scatter.txt file from the extracted firmware folder, and select the “Download Only” mode. Click the “Download” button. Power off your phone completely (remove and reinsert the battery if it’s removable), then connect it to your PC with a USB cable to start the flashing process.

Device-Specific Troubleshooting for Advan i45
- Restoring Lost 4G Signal / Invalid IMEI: A common issue on MediaTek devices after a bad flash or root attempt is the loss of the phone’s IMEI number, resulting in no network signal (“Sinyal 4G Hilang”). Flashing this full stock ROM is the essential first step to fix this, as it restores the original modem and baseband files. If the IMEI is still null after flashing, you may need to use a separate dedicated tool to restore it.
- PC Not Detecting 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.
- Overheating Issues: If your phone overheats during normal use, it could be due to rogue background processes. A clean flash with this stock ROM can help resolve software-related overheating by restoring the system to a clean, optimized state.
FAQs
- Q1. My Advan i45 is dead after trying to root it. 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.
- Q2. My 4G signal is gone and the IMEI says “Invalid.” Will this ROM fix it?
- This ROM is the most important first step. It will restore the modem files required for the signal to work. In many cases, this alone fixes the issue. However, if the IMEI number itself is erased (shows as null or invalid), you may need an additional tool to repair the IMEI after successfully flashing this firmware.
- Q3. Will I lose my data by flashing this firmware?
- Yes, the SP Flash Tool process will completely erase the phone’s internal 8GB 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 5.1 Lollipop for the Advan i45.
