The Advan i4C is a 4-inch, entry-level 4G LTE smartphone from 2016, designed as an affordable option for accessing fast mobile data. It is powered by a Spreadtrum SC9830 processor and runs on Android 5.1 Lollipop. The device was released in at least two internal storage variants: 4GB and 8GB. This guide provides the official stock firmware packages for both versions.
This is a complete firmware package in the .pac format, designed for flashing with the SPD (Spreadtrum) Upgrade Tool. It is the best solution for fixing critical software issues such as a completely dead phone (mati total), a device stuck on the Advan boot logo, or installing a clean OS to remove viruses.
Disclaimer: Flashing this firmware will completely erase all data from your phone’s internal storage. Please back up any important files if possible before proceeding.

Device-Specific Troubleshooting for Advan i4C
- CRITICAL – Choose the Right Firmware: The most important step is to use the firmware that matches your phone’s hardware. If you have the 8GB version, you must use the 8GB firmware. If you flash the wrong one, the process will fail with a “partition size” error, or it could brick your device. If you are unsure, try the 4GB version first, as it was more common.
- Tool is Stuck on “Checking Baudrate”: This is the most common error and it signifies a driver or connection problem. Uninstall and reinstall the Spreadtrum drivers, use a different USB port (preferably a main one on the back of your PC), and try a different USB cable.
- “Failed: Uart send error”: This error also points to a communication problem. Ensure the drivers are correct and that you are pressing the Volume Down button firmly when connecting the device to start the flash.
- Virus Removal: Due to its older security patch level, the i4C is susceptible to malware. If your phone is showing ads or installing apps on its own, a full firmware flash is the only guaranteed way to completely clean the system.
FAQs
- Q1. My Advan i4C is totally dead. Will this fix it?
- Yes. If the cause of the dead device is corrupted software (a “hard brick”), then flashing this official
.pacfirmware is the standard procedure to unbrick it and restore it to working condition. - Q2. How do I know if I have the 4GB or 8GB version?
- If you can turn on the phone, you can check in “Settings” > “Storage.” If the phone is bricked and you don’t know, it is safest to try flashing one of the 4GB firmware versions first. The tool will likely give an error if it’s the wrong one, which is safer than potentially damaging the device with an incompatible ROM.
- Q3. The flash tool doesn’t detect my phone. What’s wrong?
- This is a driver issue 99% of the time. Ensure the Spreadtrum drivers are installed correctly. Your PC should make a connection sound, and a “Spreadtrum” device should briefly appear in the Windows Device Manager when you connect the phone correctly.
- Q4. Will this process remove the Google Account (FRP) lock?
- No. Flashing the stock firmware will restore the original operating system, but it does not bypass Factory Reset Protection (FRP). You will still need to enter the credentials of the last Google account that was synced to the phone.
