Infinix Smart 2 X5515F Firmware (Flash File) Drivers, Tools & Guide
The Infinix Smart 2 X5515F frequently enters my workshop with issues like FRP locks, bootloop problems, or devices stuck on the Infinix logo. This guide consolidates all necessary resources: firmware files, required tools, and the precise procedure I use daily.
Before starting, extract firmware to a straightforward folder path such as C:FirmwareX5515F. SP Flash Tool may fail to locate the scatter file if the path contains spaces or special characters. This simple step prevents unnecessary troubleshooting.
Eight firmware builds are available for the Infinix Smart 2 X5515F, spanning multiple Android versions and security patch levels. If one build fails, attempt an alternative version. The original 2018 release means USB driver installation on newer Windows versions (10/11) may require manual setup. Stock firmware ships with Android 8.1 Oreo (XOS 3.3), defining default apps, security features, and interface after flashing.
Eight firmware versions archived for the Infinix Smart 2 X5515F cover multiple Android builds and security patch levels. As part of Transsion Holdings, Infinix devices share similar chipset architectures and flashing procedures across the Smart 2 series.
Your Infinix Smart 2 X5515F firmware arrives as a compressed ZIP file. Download and extract using WinRAR or 7-Zip. After extraction, verify the scatter file presence in the folder before proceeding.
Flashing returns the device to factory condition. All stored data—photos, messages, apps—will be erased. This clean state resolves stuck logos, FRP locks, software corruption, and performance issues.
Infinix Smart 2 X5515F Hard Reset Guide
To factory reset Infinix Smart 2 X5515F without a computer, power off the device completely. Hold Volume Up and Power simultaneously until the recovery menu appears. Navigate to “Wipe Data/Factory Reset” using volume keys and confirm with Power.
A hard reset erases all data and restores Infinix Smart 2 X5515F to its original factory state. This resolves most software problems—slow performance, app crashes, forgotten screen locks, and bootloops. If issues persist after a factory reset, a full firmware flash using SP Flash Tool follows in subsequent sections.
Infinix Smart 2 X5515F FRP Bypass
The quickest method to bypass FRP on Infinix Smart 2 X5515F involves using a free Android apps launcher that provides settings access during setup.

Which Firmware Version Should I Download?
This question appears frequently in comments, so I created a simple guide. Match your situation to the table and select the appropriate file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V473, download this version. It is the latest Infinix Smart 2 X5515F firmware available. |
| FRP / Google account lock only | Refer to the FRP bypass guide above, you likely do not require full firmware for this. |
| Phone slow after a recent OTA update | Try V395, sometimes the latest OTA introduces bugs; an older build performs better. |
| IMEI missing after a previous flash | Re-flash V473 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V473 failed with a flash error | Attempt V395 instead and double-check scatter file selection before assuming firmware issues. |
| Restoring to factory / warranty repair | V473, clean state, fresh start. |
My standard approach for MTK devices: always attempt the latest version first. I have observed users spending excessive time with older builds when the newest would have succeeded. Only move to an older version if the latest fails multiple times, and confirm it is a driver issue, not firmware-related.

Important: The Infinix Smart 2 X5515F (X5515F) should not be confused with other Smart 2 variants that may have different chipsets or regional firmware. Even devices in the same Smart 2 line can use completely different processors. Always verify your exact model code “X5515F” in Settings > About Phone before downloading any firmware from this page.
- The model code on your phone must match X5515F exactly. Even a single letter variant (like adding or dropping an “i” or “s”) can mean a different chipset inside.
- Your chipset should be MediaTek MT6739. Recovery mode shows this information if you are not sure.
- Do not mix firmware from other download sites with the files on this page.
- If the downloaded file is much smaller than what is listed in the table above, re-download it, partial files will fail.
Before You Start: Infinix Smart 2 X5515F Requirements
Do not skip this section. Most failed Infinix flashes result from rushing preparation steps. The VCOM driver installation is essential for the Infinix Smart 2 X5515F and other MediaTek devices. Windows may display the device in Device Manager, but SP Flash Tool will not detect it without proper VCOM driver installation.
- Back Up IMEI Numbers: Dial *#06# and record both IMEI numbers now. You will need these if you require IMEI restoration after flashing.
- Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
- Back Up Your Data: Back up all data—photos, contacts, WhatsApp chats, important files. Flashing erases the device completely.
- Charge Your Device: Maintain at least 50% battery. A device powering off during flashing is difficult to recover.
- USB Cable & PC: Use a proper data USB cable—not a charge-only cable—and a Windows computer with available USB ports.
- Install Required Drivers:
Install Stock Firmware on Infinix Smart 2 X5515F
We use SP Flash Tool for this process. For older devices, I recommend attempting SP Flash Tool v5.1924 first. Newer SP Flash Tool versions require a DA (Download Agent) file absent in older firmware packages, causing “Auth” errors. If SP Flash Tool requests an auth file you lack, switch to MTK Client—it handles Secure Boot automatically. Download SP Flash Tool for Windows or SP Flash Tool for Linux and follow these steps. The complete SP Flash Tool guide provides additional detail if needed.
- Download and Extract:
- Download the correct firmware package from the links above.
- Extract the ZIP to a simple folder path—avoid paths with spaces or special characters, as flash tools may encounter issues.
- Install the Listed Drivers:
- Confirm all drivers listed above are installed and your PC has been restarted since installation. Skipping restarts causes driver failures.
- Load the Firmware File:
- Click “Scatter-loading” and navigate to the firmware extraction folder to select the “scatter.txt” file.
- Connect Your Device:
- Power off your phone completely—not sleep mode, fully off.
- Connect to your PC via USB cable. The flash tool will detect it automatically.
- Start Flashing:
- Click “Download” to begin.
- Do not disconnect, move the cable, or touch the device until completion. Disconnecting mid-flash bricks devices.
- Wait and Reboot:
- Once flashing completes successfully, disconnect the device.
- Power on your device. The first boot takes longer than usual—allow up to 8 minutes.
What Is Normal After a Infinix Smart 2 X5515F Flash?
Here is what is completely normal after a successful flash:
- How to know the flash was successful: SP Flash Tool displays a green circle or checkmark when done. If visible, the flash completed successfully.
- All your apps are gone, this is expected. Reinstall them from the Play Store. If you had a Google account backup active, it will offer to restore apps automatically during setup.
- Wi-Fi, Bluetooth, and mobile data should function immediately after setup. If mobile data fails, go to Settings, SIM and Network, and manually re-enter your APN—flash sometimes clears carrier settings.
- The phone may request language and region again, this is normal after a flash. You start from a clean state, so the setup wizard runs as it would for a new device.
- Dial *#06# immediately after setup to check your IMEI. Do this before inserting a SIM card. If it displays “unknown” or “null”, follow the IMEI repair guide before proceeding.
- Battery percentage may appear inaccurate for the first day. Battery statistics calibrate during normal use. Fully charge the phone once without interruption to stabilize readings.
- Be cautious when re-adding your Google account, if not removed before flashing, an FRP prompt may appear. Add it fresh during setup wizard, not through Settings.
Fix Common Infinix Smart 2 X5515F Firmware Errors
- Infinix Smart 2 X5515F Not Recognized by SP Flash Tool:
- This is typically a driver issue, not cable-related. Reinstall VCOM drivers for the X5515F, restart your PC, and retry before altering other settings.
- If unresolved, switch to a USB 2.0 port—USB 3.0 ports frequently cause detection issues with MediaTek devices.
- Still not functioning? Temporarily disable antivirus—it can block VCOM driver loading without error messages.
- Boot Loop After Flashing:
- Enter recovery mode and perform a factory reset. Most post-flash bootloops on MediaTek stem from cached data conflicts—recovery wipe resolves this without reflashing.
- Wrong Scatter File / Firmware Mismatch:
- If SP Flash Tool errors at download start, verify your scatter file first. Scatter file and device build mismatches cause frequent flash errors.
- “Download DA FAIL” Error:
- This error appears regularly. It almost always indicates improperly installed VCOM drivers. Reinstall them, restart your PC, and retry. If still unresolved, try SP Flash Tool v5.1924—older devices respond better to this version.
- Error 8038 (BROM Error):
- The device fails to enter BROM mode correctly. Power it off completely and, if possible, remove the battery for 30 seconds. Reconnect and retry. Some MediaTek devices require holding Volume Down while plugging in the USB cable to enter BROM mode.
- Auth File / Secure Boot Error in Newer SP Flash Tool:
- Newer SP Flash Tool versions require DA (Download Agent) authentication for devices with Secure Boot enabled. Without this file, use MTK Client instead—it handles Secure Boot automatically and simplifies the process.
Missing IMEI or Corrupt Baseband on Infinix Smart 2 X5515F After Flashing?
A missing or unknown IMEI is common after MediaTek flashes. The NVRAM partition storing IMEI and calibration data sometimes does not survive flashing intact. This appears alarming but is fixable. Follow these steps:
- Check your drivers first: Install the Mediatek CDC Driver if not already present—IMEI repair tools cannot detect your device without it. This step is frequently overlooked.
- Use SN Write Tool or Maui Meta: SN Write Tool is the primary option—straightforward and effective on most MTK devices. Maui Meta serves as an alternative if SN Write fails to connect. Learn more about using SN Write Tool here.
- Run the repair:
- Connect your device to the computer.
- Enter the original IMEI numbers for both SIM slots—the numbers recorded before flashing.
- Click “Start” and allow completion without interrupting the connection.
- Verify after reboot: Once done, reboot your phone and dial *#06#. IMEI numbers should return. If still displaying null, repeat the process—sometimes the first attempt does not complete correctly.
