Advan S40 Firmware Flash File Download [Stock Rom]
The Advan S40 is a compact, ultra-budget 4-inch smartphone from the Indonesian brand Advan, designed for basic communication needs. As highlighted in the warning above, this phone exists in two different hardware versions, making software restoration a delicate process. This guide provides the official stock firmware for both the MediaTek (MTK) and Spreadtrum (SPD) variants.
CRUCIAL WARNING: Check Your Chipset Before Flashing!
The Advan S40 was released with two completely different and incompatible hardware versions:
- One with a MediaTek (MTK) chipset, which requires the QGDP Tool.
- Another with a Spreadtrum (SPD) chipset, which requires the SPD Upgrade Tool.
Flashing the wrong firmware type on your phone will cause a permanent hard brick, making it unrecoverable. Before downloading any file, if your phone can turn on, go to Settings > About Phone and check the CPU/Processor information. You MUST match the firmware to your phone’s chipset.
Important Note: Please read the warning carefully and identify your phone’s correct chipset before proceeding. Flashing any firmware will completely erase all your personal data.

❓ Frequently Asked Questions (FAQs)
- Q1. How can I be 100% sure which Advan S40 version I have?
- If the phone turns on, go to
Settings > About Phone. Look for “Build Number” or “Processor” information. If it mentions “MTK” or “MT6737M,” use Version 1. If it mentions “SPD” or “SC9850,” use Version 2. If the phone is bricked and you cannot check, flashing is a major risk. Do not guess. - Q2. I flashed the wrong version by mistake. Is my phone dead?
- Unfortunately, flashing firmware from a different chipset (e.g., SPD firmware on an MTK phone) is called “cross-flashing” and almost always results in a hard brick that is not recoverable with standard USB tools. This is why identification is the most important step.
- Q3. Why is my phone so slow, even after flashing?
- A clean flash restores the phone to its maximum potential speed. However, the Advan S40 has very low-end hardware (512MB RAM, 4GB storage). It is only designed for the most basic tasks like phone calls, SMS, and very light apps. Modern applications will not run well on this device.
