Infinix Zero 8 X687 Firmware (Flash File) Drivers, Tools & Guide
Infinix Zero 8 X687 devices frequently arrive with common software issues like FRP locks, bootloops, or getting stuck on the Infinix logo. This guide provides everything needed to resolve these problems using official firmware and tools.
Before starting, extract firmware to a simple folder path such as C:FirmwareX687. SP Flash Tool may have trouble locating the scatter file if the folder path contains spaces or special characters. This small step prevents frustrating delays during the flashing process.
The stock firmware includes Android 10 (XOS 7), which determines default apps, security features, and the interface after flashing. Released in 2020, the Infinix Zero 8 X687 may require manual USB driver installation on newer Windows versions (10/11) for proper connectivity. This page offers 14 firmware builds covering multiple Android versions and security patch levels. If one build fails, try an alternative version.
Firmware integrity was verified across two independent sources to confirm these are authentic, unmodified stock ROMs. With 14 versions archived for the Infinix Zero 8 X687, this page covers multiple Android builds and security patch levels.
Your Infinix Zero 8 X687 firmware comes as a compressed ZIP file. Download and extract it using WinRAR or 7-Zip. After extraction, check the folder for the scatter file before proceeding.
Note that flashing stock firmware erases all data—this is intentional for resolving software issues including FRP lock, app problems, slow performance, forgotten pattern locks, devices stuck on logos, Wi-Fi and Bluetooth issues, battery drain, and soft brick situations.
How to Wipe Infinix Zero 8 X687 to Factory Settings
To factory reset Infinix Zero 8 X687 without a computer, power off the device completely, then hold Volume Up and Power simultaneously until the recovery menu appears. Use 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 8 X687 to its original factory state. This resolves 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.
Infinix Zero 8 X687 Google Account Bypass After Reset
The fastest way to bypass FRP on Infinix Zero 8 X687 is to use a free Android apps launcher that lets you access settings during setup.

How to Pick the Correct Infinix Zero 8 X687 Firmware
The most common error people make is flashing firmware meant for a different variant. Before downloading, verify your exact device identity:
- Check About Phone: Go to Settings and find your exact model number. It must read “X687”, not a similar name, the exact code.
- Match the Chipset: This firmware is designed for MediaTek MT6785 Helio G90T. A different processor will prevent successful flashing.
- Look at the Build Number: The build string in your current software should reference the Zero 8 line. Compare it with the firmware table below.
- Check Recovery Mode: Power off, hold Volume Up + Power until recovery appears. The screen displays your chipset and current build, use this to confirm.
- Compare File Details: Ensure the version in the download table matches your device and region.

Which Firmware Version Should I Download?
This question appears frequently in comments, so here is a simple guide. Find your situation in the table and go directly to the right file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V611, download this one. It is the latest Infinix Zero 8 X687 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 V597, sometimes the latest OTA introduces new bugs and an older build runs better. |
| IMEI missing after a previous flash | Re-flash V611 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V611 failed with a flash error | Try V597 instead and double-check your scatter file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V611, 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 fully compatible with your exact device model. See the firmware selection guide above if you are not sure.
Important: The Infinix Zero 8 X687 (X687) should not be confused with other Zero 8 variants that may have different chipsets or regional firmware. Even devices in the same Zero 8 line can use completely different processors. Always verify your exact model code “X687” in Settings > About Phone before downloading any firmware from this page.
- Your model number is a variant of X687 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 8 X687 Flash Setup Checklist
Do not skip this section. Most failed Infinix flashes result from rushing through preparation steps. The VCOM driver installation is essential for the Infinix Zero 8 X687 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.
- Back Up IMEI Numbers: Dial *#06# and write down both IMEI numbers now. You will need these if you need to restore your IMEI after flashing.
- Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
- Back Up Your Data: Back up everything, photos, contacts, WhatsApp chats, important files. Flashing wipes the device completely.
- Charge Your Device: At least 50% battery. A device that powers off during a flash is very 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:
Infinix Zero 8 X687 Firmware Installation Guide
We are using SP Flash Tool for this. For older devices, I recommend trying SP Flash Tool v5.1924 first. Newer versions of SP Flash Tool require a DA (Download Agent) file that older firmware packages do not include, causing “Auth” errors. 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.
- Download the Firmware Package:
- Use the download links in the table above to get the correct firmware file for your device.
- Extract the archive with WinRAR or 7-Zip. Use a short folder path like
D:flashto avoid issues with some tools.
- Check Drivers:
- All drivers from the prerequisites must be installed before connecting your device. Restart your computer after installing them.
- 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:
- Press “Download” to begin writing the firmware to your device.
- Do not unplug the phone, close the flash tool, or interact with the device until the process is 100% complete.
- Wait and Reboot:
- After the tool confirms the flash is complete, safely disconnect your phone.
- Press the power button to start your device. The initial boot is slow, wait up to 8 minutes before assuming there is a problem.
Post-Flash Behavior on Infinix Zero 8 X687
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.
- 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.
- 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 your apps automatically during setup.
- 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.
- Notification sounds and ringtones will be back to factory defaults. Any custom tones you had set before will need to be re-downloaded and re-assigned in Settings.
- First boot takes 3 to 8 minutes, do not force-reboot the device. The operating system is setting itself up from scratch. Interrupting this is how devices end up in bootloops.
- Dial *#06# immediately after setup to check your IMEI. Do this before you insert a SIM card. If it shows “unknown” or “null”, follow the IMEI repair guide below before doing anything else.
What to Do if Infinix Zero 8 X687 Flash Fails
- Infinix Zero 8 X687 Not Recognized by SP Flash Tool:
- In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the X687, 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.
Missing IMEI or Corrupt Baseband on Infinix Zero 8 X687 After Flashing?
A missing or unknown IMEI is one of the most common issues 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.

Frequently Asked Questions
Q1: How do I enter recovery mode?
A: Power the device off completely, then hold Volume Up + Power at the same time until the recovery menu appears. The recovery menu displays the build number which you can use to verify your firmware version before flashing.
Q2: Is this firmware compatible with other Infinix models?
A: No. This firmware is built specifically for the Infinix Zero 8 X687 running on the MediaTek MT6785 Helio G90T chipset. Even variants of the Zero 8 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.
Q3: What if the flash fails halfway through?
A: Do not panic and do not disconnect the phone. Close SP Flash Tool, restart it, and try the flash again from the beginning. In most cases, a failed flash just means the process needs to be repeated. The device is usually still detectable by the flash tool even after a failed attempt.
Q4: 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.
Q5: 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.
Q6: How long does the flashing process take?
A: The actual flash usually takes between 3 and 10 minutes depending on the firmware size and USB connection speed. The first boot after flashing takes another 3 to 8 minutes. Do not interrupt the device during either stage. If the progress bar in SP Flash Tool appears stuck, give it a few more minutes before assuming something went wrong.
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 go back to an older firmware version?
A: It is technically possible on some MediaTek builds, but downgrading can cause security issues and app compatibility problems. If the latest version is causing trouble, leave a comment below, there is usually a better fix than rolling back.
