# Micromax Firmware Guide: Finding and Flashing Stock ROMs > Learn how to identify the correct Micromax firmware for your device and use tools like SP Flash Tool, SPD ResearchDownload, and QFIL to flash stock ROMs. By [Admin](https://www.filefirmware.com/author/admin), Mobile Repairing Technician, 16 years · Updated November 06, 2026 · In [Brand Guides](https://www.filefirmware.com/blog/category/brand-guides) Web page: To restore a Micromax device, you must use a stock ROM that matches your specific model and chipset. Depending on the hardware, you will typically use SP Flash Tool for MediaTek devices, SPD ResearchDownload for Unisoc/SPD devices, or QFIL for Qualcomm devices. ## Safety Precautions Before Flashing Flashing firmware is a high-risk operation that can permanently damage your device if performed incorrectly. Before proceeding, adhere to these safety rules: 1. **Verify the Model:** Always confirm that the firmware matches the exact device model before flashing. Installing firmware for a similar but different model can hard-brick the phone. 2. **Back Up Data:** Flashing can erase all internal storage. Back up your personal data first. 3. **Battery Levels:** Ensure the battery is charged above 50%. Do not disconnect the device from the computer during the flashing process. 4. **Avoid Data Loss:** * For MediaTek devices, always use the "Download Only" mode. Using "Format All + Download" will erase the IMEI and NVRAM calibration. * For SPD/Unisoc devices, leave the "Erase NV" option unticked unless you specifically intend to wipe the IMEI and calibration data. Security bypasses, including FRP (Google account) removal, IMEI changing, or carrier-lock circumvention, are out of scope for this guide. ## Identifying Your Micromax Chipset and Tool Micromax uses several different chipset providers. The tool you use depends entirely on the processor inside your phone. Based on the 600 most recently added files in our library, the following chipsets and tools are most common: ### MediaTek (MTK) MediaTek is the most prevalent chipset in Micromax devices. Common chipsets include the MT6582, MT6572, MT6737M, MT6735M, MT6580, MT6577, MT6592, MT6589, MT6573, and MT6575. These devices are flashed using **SP Flash Tool**. ### SPD / Unisoc Devices using Spreadtrum (SPD) or Unisoc chipsets require **SPD ResearchDownload** (also known as UpgradeDownload). ### Qualcomm A smaller number of Micromax devices use Qualcomm chipsets. These require **QFIL**, which is part of the Qualcomm QPST tool suite. ## How to Choose the Correct Stock ROM Selecting the wrong file is the most common cause of device failure. When searching for a ROM in the [/category/micromax](https://www.filefirmware.com/category/micromax) section, check the following: * **Model Number:** Match the model number found on the device sticker or in the settings menu exactly. * **Android Version:** Micromax devices span various versions. Our library contains files for Android 4.4, 5.1, 6.0, 7.0, 8.0, 8.1, and 9. * **Hardware Version:** Some models have different hardware revisions (e.g., HW V1.0 vs HW V2.0). Ensure the firmware version matches your hardware revision if specified in the package name. ## Flashing MediaTek Devices with SP Flash Tool For devices using MediaTek chipsets, follow these steps to reflash the stock ROM. 1. **Install Drivers:** Install the [MediaTek VCOM / USB drivers](https://www.filefirmware.com/blog/installing-mediatek-vcom-drivers-for-sp-flash-tool) on your PC to ensure the computer can communicate with the device in flash mode. 2. **Launch SP Flash Tool:** Open the application on your computer. 3. **Load the Scatter File:** In the "Scatter-loading File" field, click choose and select the scatter file from your firmware folder. This file is typically named `MTxxxx_Android_scatter.txt`. For more information on this file, see [What is a Scatter File?](https://www.filefirmware.com/blog/what-is-a-scatter-file-loading-mediatek-firmware-in-sp-flash-tool). 4. **Select Flash Mode:** Ensure the dropdown menu is set to **"Download Only"**. Do not use "Format All + Download" as this will erase your IMEI and NVRAM calibration. You can read more about this distinction here: [/blog/sp-flash-tool-download-only-vs-format-all-download](https://www.filefirmware.com/blog/sp-flash-tool-download-only-vs-format-all-download). 5. **Prepare the Device:** Power the phone off completely. 6. **Connect the Device:** Connect the phone to the PC via USB. If the tool does not detect the device, try holding the Volume Up or Volume Down button while connecting the cable. 7. **Start Flashing:** Click the "Download" button in SP Flash Tool. The process is complete when a green checkmark appears. For a more detailed walkthrough, refer to the [How to Use SP Flash Tool Guide](https://www.filefirmware.com/blog/how-to-use-sp-flash-tool-mediatek-firmware-flashing-guide). ## Flashing SPD/Unisoc and Qualcomm Devices ### SPD/Unisoc Devices Devices using SPD or Unisoc chipsets generally use `.pac` files. 1. **Tool Setup:** Open SPD ResearchDownload or UpgradeDownload. 2. **Load Firmware:** Load the `.pac` firmware file into the tool. 3. **NV Settings:** Ensure "Erase NV" is unticked to preserve your IMEI. 4. **Connection:** Follow the specific connection sequence for your model. Detailed steps can be found in the [Connecting Unisoc Phones to SPD ResearchDownload](https://www.filefirmware.com/blog/connecting-unisoc-phones-to-spd-researchdownload) guide. 5. **Execution:** Start the download process and wait for the completion signal. Further instructions are available in the [Flashing .pac Files Guide](https://www.filefirmware.com/blog/flashing-pac-files-with-spd-researchdownload-guide) and the [SPD ResearchDownload Firmware Flashing Guide](https://www.filefirmware.com/blog/how-to-use-spd-researchdownload-firmware-flashing-guide). ### Qualcomm Devices Qualcomm devices are flashed using QFIL. 1. **EDL Mode:** The device must be put into Emergency Download (EDL) mode. See [How to Get Qualcomm Phones into EDL Mode for QFIL](https://www.filefirmware.com/blog/how-to-get-qualcomm-phones-into-edl-mode-for-qfil) for instructions. 2. **Configuration:** Open QFIL and select the correct programmer file and XML files provided in the firmware package. 3. **Flashing:** Execute the flash process. If you encounter a "Sahara Fail" error, refer to the [How to Fix QFIL Sahara Fail Error](https://www.filefirmware.com/blog/how-to-fix-qfil-sahara-fail-error) guide. Detailed steps are available in the [How to Use QFIL Guide](https://www.filefirmware.com/blog/how-to-use-qfil-qualcomm-firmware-flashing-guide). ## Example Micromax Firmware Files Below are examples of stock firmware files available in our library.

The SP Flash Tool is commonly used for MediaTek devices. It requires MediaTek VCOM / USB drivers and the scatter file (MTxxxx_Android_scatter.txt) to load the firmware. ### What is the risk of using Format All + Download in SP Flash Tool? Using Format All + Download on MediaTek devices erases the IMEI and NVRAM calibration. It is recommended to use Download Only instead. ### What should I check before flashing a Micromax phone? Always confirm the firmware matches the exact device model, back up all personal data, and ensure the battery is charged above 50%. ## Firmware files for this guide - [Micromax X809](https://www.filefirmware.com/file/micromax-x809-107760) — 8 MB · June 16, 2026 - [Micromax X770](https://www.filefirmware.com/file/micromax-x770-107752) — 3 MB · June 16, 2026 - [Micromax X807](https://www.filefirmware.com/file/micromax-x807-107751) — 4 MB · June 16, 2026 - [Micromax X749](https://www.filefirmware.com/file/micromax-x749-107746) — 4 MB · June 16, 2026 - [Micromax X750](https://www.filefirmware.com/file/micromax-x750-107745) — 4 MB · June 16, 2026 - [Micromax X754](https://www.filefirmware.com/file/micromax-x754-107743) — 4 MB · June 16, 2026 - [Micromax X756](https://www.filefirmware.com/file/micromax-x756-107742) — 4 MB · June 16, 2026 - [Micromax X741](https://www.filefirmware.com/file/micromax-x741-107739) — 18 MB · June 16, 2026 - [Micromax X746](https://www.filefirmware.com/file/micromax-x746-107737) — 8 MB · June 16, 2026 - [Micromax X748](https://www.filefirmware.com/file/micromax-x748-107735) — 4 MB · June 16, 2026 - [Micromax X744](https://www.filefirmware.com/file/micromax-x744-107730) — 4 MB · June 16, 2026 - [Micromax X556](https://www.filefirmware.com/file/micromax-x556-107715) — 3 MB · June 16, 2026 *This guide was drafted with AI assistance from File Firmware's firmware database and reviewed and edited by Admin.* --- *Source: File Firmware — .
