Infinix Zero 8i X687B Firmware (Flash File) Drivers, Tools & Guide
The Infinix Zero 8i X687B comes into the shop regularly with issues such as FRP locks, bootloops, or being stuck on the Infinix logo. This guide covers all of it. I have put everything you need in one place: the firmware, the tools, and the exact process I use myself.
One thing I always recommend before you start: extract the firmware to a simple folder path, something like C:FirmwareX687B. SP Flash Tool can sometimes have trouble locating the scatter file if the folder path contains spaces or special characters. It is a small thing, but it saves a frustrating few minutes of wondering why the tool is not loading the file.
The Infinix Zero 8i X687B runs on a MediaTek MT6785 Helio G90T chipset (MediaTek), which means you will use SP Flash Tool and VCOM/MTK drivers for flashing. These are included in the prerequisites below. The stock firmware ships with Android 10 (XOS 7), which determines the default apps, security features, and interface you will see after flashing. The Infinix Zero 8i X687B was originally released in 2020, which means USB driver compatibility on newer Windows versions (10/11) may require manual installation rather than plug-and-play.
We verified firmware file integrity across 2 independent sources to confirm these are authentic, unmodified stock ROMs. The Infinix Zero 8i X687B was released in 2020. This page is maintained with the latest available firmware builds as they become available.
Your Infinix Zero 8i X687B firmware comes as a compressed ZIP file. Download and extract it using WinRAR or 7-Zip. Once extracted, open the folder and confirm it contains the scatter file before proceeding.
Flashing replaces your current software completely and wipes all personal data. This is by design, it is what clears out FRP locks, bootloops, pattern locks, app crashes, and other software-level problems that a regular reset cannot fix.
FRP Removal for Infinix Zero 8i X687B
The fastest way to bypass FRP on Infinix Zero 8i X687B is to use a free Android apps launcher that lets you access settings during the setup wizard. After flashing or performing a factory reset you may see a Google account lock (FRP). Our free Android apps launcher is the fastest way to get past it. This is also why I always recommend removing your Google account before flashing, it avoids this problem entirely.
Hard Reset Infinix Zero 8i X687B
To factory reset Infinix Zero 8i X687B without a computer, power off the device completely, then hold Volume Up and Power at the same time until the recovery menu appears. Use the volume keys to navigate to “Wipe Data/Factory Reset” and confirm with the Power button.
A hard reset erases all data and restores Infinix Zero 8i X687B to its original factory state. This fixes most software problems, slow performance, app crashes, forgotten screen locks, and bootloops. If the issue persists after a factory reset, a full firmware flash using SP Flash Tool is covered in the following sections.
Verify Your Infinix Zero 8i X687B Model Before Downloading
The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Open About Phone: Your device model must read “X687B” exactly. Even small differences in the code can mean a completely different chipset and partition layout.
- Verify the Chipset Type: This firmware targets MediaTek MT6785 Helio G90T specifically. Flashing it on a different chipset will fail or could brick the device.
- Check Your Current Firmware Version: Compare your build number with the versions listed in the download section to decide which file to use.
- Use Recovery Mode: If you cannot access Settings (phone is stuck or locked), boot into recovery mode to read the build and chipset details from the screen.
- Regional Compatibility: Some Infinix firmware packages target specific regions. Confirm the download matches your device origin.
Why Do We Need Infinix Zero 8i X687B Firmware?
The Infinix Zero 8i X687B uses a MediaTek chipset, and SP Flash Tool is the standard method for firmware recovery on MTK devices. Here is what flashing the stock firmware can help with:
- Clear a forgotten screen lock, PIN, or pattern without needing the original credentials.
- Fix startup loops, lagging, and freezing on your device.
- Remove persistent malware or adware that survives a factory reset.
- Restore the original Infinix stock ROM to keep your warranty valid.
- Unlock your device if it has been locked or disabled.
- Restore system apps that were accidentally removed or corrupted.
- Recover from “Download DA FAIL” errors and Secure Boot authentication issues specific to the MediaTek chipset in your device.

Which Firmware Version Should I Download?
This is the question I get asked most often in the comments, so I put together a simple guide. Find your situation in the table and go straight to the right file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V215, download this one. It is the latest Infinix Zero 8i X687B firmware available. |
| FRP / Google account lock only | See the FRP bypass guide above, you likely do not need the full firmware for this. |
| Phone slow after a recent OTA update | Try V213, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V215 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V215 failed with a flash error | Try V213 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V215, clean state, fresh start. |
My general approach with MTK devices: always try the latest version first. I have seen people spend a lot of time trying older builds when the newest one would have worked fine. Only move to an older version if the latest fails more than once, and make sure it is a driver issue you are solving, not a firmware issue.

Only download firmware that is fully compatible with your exact device model. See the firmware selection guide above if you are not sure.
Important: The Infinix Zero 8i X687B (X687B) should not be confused with other Zero 8i variants that may have different chipsets or regional firmware. Even devices in the same Zero 8i line can use completely different processors. Always verify your exact model code “X687B” in Settings > About Phone before downloading any firmware from this page.
- Your model number is a variant of X687B with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from MediaTek MT6785 Helio G90T. Confirm in recovery mode before proceeding.
- You downloaded the file from a source other than this page.
- The file size differs significantly from the sizes listed in the table above, a size mismatch usually means a partial download, which will fail mid-flash.
Infinix Zero 8i X687B Flash Setup Checklist
Do not skip this section. Most failed Infinix flashes come from rushing through the preparation steps. The VCOM driver installation is essential for the Infinix Zero 8i X687B and other MediaTek devices. Windows may show the device in Device Manager and SP Flash Tool will still not detect it if the correct VCOM driver is not installed.
- Save Your IMEI Numbers: Type *#06# in the phone dialer and note down both numbers. These are your device identifiers for the cellular network. If flashing wipes them, you will need the originals to write them back.
- Disconnect Google Accounts: Before you start anything, remove all Google accounts from the phone. Settings then Accounts then tap each Google account and remove it. This avoids the FRP verification screen that appears after flashing if accounts were still linked.
- Create a Backup: Copy your data to your computer or an SD card. Flashing replaces the entire software on the phone, which means all personal data, apps, and settings will be permanently deleted.
- Charge First: Get the battery above 50% before starting. The flashing process takes a few minutes and the first boot takes several more. A power failure during either stage can leave the device in a state that requires more advanced recovery.
- Prepare Your PC Connection: You need a Windows computer and a USB cable that supports data transfer. Test the cable first by connecting the phone normally, if it shows up in File Explorer, the cable is good.
- Install the Right Drivers:
Infinix Zero 8i X687B Firmware Installation Guide
We are using SP Flash Tool for this. For older devices, I recommend trying SP Flash Tool v5.1924 first. The newer versions of SP Flash Tool require a DA (Download Agent) file that older firmware packages do not include, and that is what causes the “Auth” errors you may have seen. If SP Flash Tool keeps asking for an auth file and you do not have one, switch to MTK Client, it handles Secure Boot automatically. Download SP Flash Tool for Windows or SP Flash Tool for Linux and follow the steps below. The complete SP Flash Tool guide is also available if you need more detail.
- Get the Firmware Ready:
- Download the firmware file from the download section above.
- Right-click the ZIP and select “Extract Here” or use 7-Zip. Put the extracted files in a folder without spaces in the name, like
C:firmware.
- Verify Your Drivers:
- Make sure the required drivers are installed. After installing, restart your PC, drivers often do not activate until after a reboot.
- Load the Firmware File:
- Click on the “Scatter-loading” button. Navigate to the folder where you extracted the firmware and 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:
- Hit the “Download” button in the flash tool to start the process.
- Leave the phone and cable completely alone until it finishes. Any interruption during this stage risks corrupting the flash.
- Wait and Reboot:
- When the flash completes, unplug the USB cable from your phone.
- Turn on the device. First boot takes 3 to 8 minutes, do not force restart it during this time.
What to Do if Infinix Zero 8i X687B Flash Fails
- Infinix Zero 8i X687B Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the X687B, restart your PC, and try again before changing anything else.
- If that does not work, switch to a USB 2.0 port, USB 3.0 ports can cause detection issues with MediaTek devices more often than people expect.
- Still not working? Temporarily disable your antivirus. It can block the VCOM driver from loading without giving you any error message.
- Boot Loop After Flashing:
- Enter recovery mode and perform a factory reset from there. Most post-flash bootloops on MediaTek are caused by conflicts with old cached data, a wipe from recovery usually fixes this without needing to reflash.
- Wrong Scatter File / Firmware Mismatch:
- If SP Flash Tool throws an error as soon as you try to start the download, check your scatter file first. A mismatch between the scatter file and your device build is one of the most common causes of flash errors.
- “Download DA FAIL” Error:
- This error comes up regularly. It almost always means the VCOM driver is not properly installed. Reinstall it, restart your PC, and try again. If that still does not work, try switching to SP Flash Tool v5.1924, older devices sometimes respond better to the older version.
- 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 try again. Some MediaTek devices require you to hold Volume Down while plugging in the USB cable to enter BROM mode.
- Auth File / Secure Boot Error in Newer SP Flash Tool:
- Newer versions of SP Flash Tool require a DA (Download Agent) authentication file for devices with Secure Boot enabled. If you do not have that file, switch to MTK Client instead, it handles Secure Boot automatically and is the simpler solution.
What Is Normal After a Infinix Zero 8i X687B Flash?
Here is what is completely normal after a successful flash:
- How to know the flash was successful: SP Flash Tool will show a green circle or checkmark when done. If you see that, the flash completed successfully.
- Fingerprint and face unlock data are erased during the flash. You will need to re-register your fingerprints and face data from scratch in the security settings.
- The phone may ask for language and region again, this is normal after a flash. You are starting from a clean state, so the setup wizard runs just like when the phone was brand new.
- Wi-Fi, Bluetooth, and mobile data should all work right after setup. If mobile data is not connecting, go to Settings, SIM and Network, and re-enter your APN manually, the flash sometimes clears carrier APN settings.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- Storage will show almost full capacity available since all your apps and files are gone. The system partition size varies by firmware version but is typically 4 to 8 GB on most devices.
- Battery percentage may seem inaccurate for the first day. The battery statistics are calibrated during normal use. Charge the phone fully once without interruption and the readings will stabilize.
Missing IMEI or Corrupt Baseband on Infinix Zero 8i X687B After Flashing?
A missing or unknown IMEI is one of the most common things I see after a MediaTek flash. It happens because the NVRAM partition, which stores your IMEI and calibration data, sometimes does not survive the flash intact. It looks alarming, but it is fixable. Here is what to do:
- Check your drivers first: Install the Mediatek CDC Driver if you have not already, without it, the IMEI repair tools will not detect your device. This is the step most people miss.
- Use SN Write Tool or Maui Meta: SN Write Tool is the first option I try, it is straightforward and works on most MTK devices. Maui Meta is the alternative if SN Write does not connect. You can 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, these are the numbers you wrote down before flashing.
- Click “Start” and let it complete without interrupting the connection.
- Verify after reboot: Once done, reboot your phone and dial *#06#. Your IMEI numbers should be back. If they are still showing null, run the process again, sometimes the first attempt does not complete correctly.

Infinix Zero 8i X687B Firmware FAQ
Q1: What should I do if I encounter an FRP lock after flashing?
A: Use our free Android apps launcher. FRP lock activates when a Google account was still signed in before flashing. This is why signing out of your Google account before flashing avoids this issue entirely.
Q2: Will flashing erase my data?
A: Yes, flashing with SP Flash Tool restores the device to factory state, including Android 10 (XOS 7) default settings. All apps, photos, contacts, and accounts will be removed. Back up everything you need before you start. There is no way to recover data once the flash is complete.
Q3: My IMEI shows “unknown” after flashing. Is my phone permanently damaged?
A: No, it looks alarming, but it is fixable. Follow the IMEI repair guide in the troubleshooting section above. For MediaTek devices, SN Write Tool or Maui Meta will handle the repair. Do not insert a SIM card until the IMEI is restored.
Q4: Do I need an internet connection during flashing?
A: No. The flashing process is entirely offline, it happens between your PC and the phone via the USB cable. You do not need internet at any point during the flash itself. You will need internet later to set up the phone and download your apps.
Q5: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix Zero 8i X687B running on the MediaTek MT6785 Helio G90T chipset. Even variants of the Zero 8i with a different letter suffix can have a completely different chipset inside. Flashing the wrong firmware can leave your phone in a state that is very difficult to recover from. Always check your exact model number in Settings.
Q6: Will flashing void my warranty?
A: Flashing official stock firmware generally does not void your warranty since you are restoring the device to its factory-intended state. However, some manufacturers may flag that the bootloader was unlocked or that the flash counter increased. Check your specific warranty terms with Infinix support if you are concerned.
Q7: Is it safe to flash during a power outage risk?
A: It is best to avoid flashing during unstable power conditions. If your PC shuts down during the flash, it can corrupt the write and leave the phone in an unbootable state. If you are in an area with unreliable power, use a laptop with a fully charged battery instead of a desktop.
Q8: Can I use a Mac or Linux computer for this?
A: The tools and drivers referenced on this page are Windows-only. If you are on Mac or Linux, your best option is to use a Windows virtual machine, or borrow a Windows PC for the 10 minutes it takes to complete the flash.
