Infinix Hot 4 X557 Firmware (Flash File) Drivers, Tools & Guide

The Infinix Hot 4 X557 regularly enters service with software issues like FRP locks, bootloops, or logo hangs. This guide consolidates the official Infinix Hot 4 X557 firmware, compatible tools, and verified procedures to resolve these problems.

Before starting, extract firmware to a straightforward folder path such as C:FirmwareX557. SP Flash Tool may fail to detect scatter files in paths with spaces or special characters—a simple workaround that prevents unnecessary troubleshooting.

The Infinix Hot 4 X557 uses a MediaTek MT6580 chipset, requiring SP Flash Tool and VCOM/MTK drivers for flashing. Currently, only one firmware build is available for this device. This stock ROM serves for recovery, unbricking, or FRP bypass. Released in 2016, the device may require manual driver installation on modern Windows systems (10/11) rather than plug-and-play functionality.

This page is updated with the latest available firmware builds sourced from verified repositories and checked for integrity. The Infinix Hot 4 X557 firmware arrives as a compressed ZIP file. Download and extract using WinRAR or 7-Zip. After extraction, verify the presence of the scatter file before proceeding.

A full flash deletes all device data: applications, accounts, photos, and settings. This process delivers a clean installation, resolving screen locks, FRP prompts, boot failures, sluggish performance, and connectivity issues.

Which Firmware Version Should I Download?

This addresses the most common question I receive. Match your situation to the table below:

Your Situation	What I Recommend
Phone is completely dead or stuck on logo	the latest version, download this file. It represents the most current Infinix Hot 4 X557 firmware available.
FRP / Google account lock only	Review the FRP bypass guide above, you likely do not require full firmware for this specific issue.
Phone slow after recent OTA update	Try the next older version, sometimes the latest OTA introduces bugs, and an older build performs better.
IMEI missing after previous flash	Re-flash the latest version first, then follow the IMEI repair guide. Do not skip the reflash step.
Latest version failed with flash error	Attempt the next older version instead and double-check scatter file selection before assuming firmware is the problem.
Restoring to factory / warranty repair	the latest version, provides a clean state and fresh start.

My standard approach for MTK devices: always try the latest version first. I have observed users spend excessive time testing older builds when the newest firmware would have functioned correctly. Only proceed to an older version if the latest fails repeatedly, and confirm it addresses a driver issue rather than a firmware problem.

What You Need Before Flashing Infinix Hot 4 X557

Do not bypass this preparation phase. Most Infinix flashing failures result from rushed setup steps. The VCOM driver installation is critical for the Infinix Hot 4 X557 and other MediaTek devices. Windows may detect the device in Device Manager, but SP Flash Tool will not recognize it without proper VCOM driver installation.

1. Back Up IMEI Numbers: Dial *#06# and record both IMEI numbers immediately. You will need these if IMEI restoration becomes necessary after flashing.
2. Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
3. Back Up Your Data: Secure all data, photos, contacts, WhatsApp chats, important files. Flashing permanently erases the device.
4. Charge Your Device: Maintain at least 50% battery. A device powering off during flashing is extremely difficult to recover.
5. USB Cable & PC: Use a data-capable USB cable, not a charge-only cable, and a Windows computer with functional USB ports.
6. Install Required Drivers:
   • VCOM Drivers
   • Infinix USB Drivers

Step-by-Step: Flash Infinix Hot 4 X557 Stock ROM

We use SP Flash Tool for this process. For older devices, I recommend trying SP Flash Tool v5.1924 initially. Newer SP Flash Tool versions require a DA (Download Agent) file not included in older firmware packages, causing “Auth” errors. If SP Flash Tool requests an auth file and you lack one, 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 offers additional details if needed.

1. Prepare the Firmware:
   • Download the firmware file from the download section.
   • Right-click the ZIP and select “Extract Here” or use 7-Zip. Place extracted files in a folder without spaces, like C:firmware.
2. Verify Your Drivers:
   • Ensure the required drivers are installed. After installation, restart your PC, drivers often require reboot to activate.
3. Load the Firmware File:
   • Click “Scatter-loading” and navigate to the firmware extraction folder to select the “scatter.txt” file.
4. 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.
5. Start Flashing:
   • Click the “Download” button in the flash tool to begin.
   • Leave the phone and cable undisturbed until completion. Any interruption risks flash corruption.
6. Wait and Reboot:
   • After flash completion, disconnect the USB cable from your phone.
   • Power on the device. First boot takes 3 to 8 minutes, avoid force restarting during this time.

Common Issues When Flashing Infinix Hot 4 X557

1. Infinix Hot 4 X557 Not Recognized by SP Flash Tool:
   • This is typically a driver issue, not a cable problem. Reinstall VCOM drivers for the X557, restart your PC, and retry before making other changes.
   • If unresolved, switch to a USB 2.0 port, USB 3.0 ports frequently cause detection problems with MediaTek devices.
   • Still not working? Temporarily disable your antivirus, it can block VCOM driver loading without error messages.
2. Boot Loop After Flashing:
   • Enter recovery mode and perform a factory reset. Most post-flash bootloops on MediaTek stem from old cached data conflicts, a recovery wipe typically resolves this without reflashing.
3. Wrong Scatter File / Firmware Mismatch:
   • If SP Flash Tool generates an error when attempting to download, verify the scatter file first. Scatter file and device build mismatches are frequent causes of flash failures.
4. “Download DA FAIL” Error:
   • This error commonly occurs. It nearly always indicates improper VCOM driver installation. Reinstall drivers, restart your PC, and retry. If persistent, try SP Flash Tool v5.1924, older devices sometimes respond better to this version.
5. Error 8038 (BROM Error):
   • The device is not entering BROM mode correctly. Power it off completely and, if possible, remove the battery for 30 seconds. Reconnect and attempt again. Some MediaTek devices require holding Volume Down while plugging in the USB cable to enter BROM mode.
6. Auth File / Secure Boot Error in Newer SP Flash Tool:
   • Newer SP Flash Tool versions require a DA (Download Agent) authentication file for devices with Secure Boot enabled. If unavailable, switch to MTK Client, it handles Secure Boot automatically and provides a simpler solution.

What Is Normal After a Infinix Hot 4 X557 Flash?

Here are normal behaviors following a successful flash:

• Successful flash confirmation: SP Flash Tool displays a green circle or checkmark when complete. If visible, the flash succeeded.
• Storage shows near-full capacity since all apps and files are erased. System partition size typically ranges from 4 to 8 GB depending on firmware version.
• Dial *#06# immediately after setup to check your IMEI. Do this before inserting a SIM card. If “unknown” or “null” appears, follow the IMEI repair guide before proceeding further.
• Re-add Google account carefully, if not removed before flashing, an FRP prompt may appear. Add the account fresh during setup wizard, not later through Settings.
• Notification sounds and ringtones revert to factory defaults. Custom tones require re-download and re-assignment in Settings.
• 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, flashing sometimes clears carrier APN 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 with a new device.

Missing IMEI or Corrupt Baseband on Infinix Hot 4 X557 After Flashing?

A missing or unknown IMEI frequently appears after MediaTek flashing. This occurs because the NVRAM partition storing IMEI and calibration data may not survive flashing intact. While alarming, it is fixable:

1. Verify drivers first: Install the Mediatek CDC Driver if not already present, IMEI repair tools cannot detect the device without it. This step is frequently overlooked.
2. Use SN Write Tool or Maui Meta: SN Write Tool is my first choice, it works reliably on most MTK devices. Maui Meta serves as an alternative if SN Write fails to connect. Learn more about using SN Write Tool here.
3. Execute 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.
4. Verify after reboot: Once done, reboot your phone and dial *#06#. IMEI numbers should return. If still showing null, repeat the process, the first attempt may not complete correctly.
