Tecno Phantom 9 AB7 Firmware (Flash File) Drivers, Tools & Guide

I have dealt with Tecno phones for some time, and the Tecno Phantom 9 AB7 is a frequent visitor in my workshop, usually with FRP locks, bootloop issues, or stuck on the Tecno 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.

I always recommend doing one thing before you start: extract the firmware to a simple folder path, something like C:FirmwareAB7. SP Flash Tool can sometimes have trouble locating the scatter file if the folder path contains spaces or special characters. This is a small detail, but it saves a frustrating few minutes of wondering why the tool is not loading the file.

The Tecno Phantom 9 AB7 was originally released in 2019, which means USB driver compatibility on newer Windows versions (10/11) may require manual installation rather than plug-and-play. There are 2 firmware files available for the Tecno Phantom 9 AB7 on this page. Pick the one that matches your current Android version for the smoothest flash. The Tecno Phantom 9 AB7 runs on a MediaTek MT6765 Helio P35 chipset (MediaTek), which means you will use SP Flash Tool and VCOM/MTK drivers for flashing. These are included in the prerequisites below.

The Tecno Phantom 9 AB7 was released in 2019. This page is maintained with the latest available firmware builds as they become available. As a Transsion Holdings brand, Tecno devices share similar chipset architectures and flashing procedures across the Phantom 9 lineup.

Your Tecno Phantom 9 AB7 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.

Bypass Google Lock on Tecno Phantom 9 AB7

The fastest way to bypass FRP on Tecno Phantom 9 AB7 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.

Factory Reset Tecno Phantom 9 AB7 Without a PC

To factory reset Tecno Phantom 9 AB7 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 Tecno Phantom 9 AB7 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.

How to Pick the Correct Tecno Phantom 9 AB7 Firmware

The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:

1. Check About Phone: Open Settings and find your exact model number. It should read “AB7”, not a similar name, the exact code.
2. Match the Chipset: This firmware is built for MediaTek MT6765 Helio P35. If your device has a different processor, it will not flash correctly.
3. Look at the Build Number: The build string in your current software should reference the Phantom 9 line. Cross-check it with the firmware table below.
4. Check Recovery Mode: Power off, hold Volume Up + Power until recovery appears. The screen displays your chipset and current build, use this to confirm.
5. Compare File Details: Make sure the version listed in the download table matches what you expect for your device and region.

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	V148, download this one. It is the latest Tecno Phantom 9 AB7 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 the next older version, sometimes the latest OTA introduces new bugs and an older build runs better.
IMEI missing after a previous flash	Re-flash V148 first, then follow the IMEI repair guide. Do not skip the reflash.
V148 failed with a flash error	Try the next older version instead and double-check your scatter file selection before assuming the firmware is the problem.
Restoring to factory / warranty repair	V148, 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.

Important: The Tecno Phantom 9 AB7 (AB7) should not be confused with other Phantom 9 variants that may have different chipsets or regional firmware. Even devices in the same Phantom 9 line can use completely different processors. Always verify your exact model code “AB7” in Settings > About Phone before downloading any firmware from this page.

Tecno Phantom 9 AB7 Flash Setup Checklist

Do not skip this section. Most failed Tecno flashes come from rushing through the preparation steps. The VCOM driver installation is essential for the Tecno Phantom 9 AB7 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.

1. IMEI Backup: Open the dialer and enter *#06#. Write both IMEI numbers down on paper or take a screenshot. If you ever need to repair your IMEI after flashing, these are essential.
2. Remove All Google Accounts: Go to Settings, Accounts, and sign out of every Google account on the device. Leaving accounts signed in triggers FRP lock after a flash, which blocks you from setting up the phone.
3. Backup Everything: Photos, contacts, messages, WhatsApp data, move it all to a computer or cloud service. The flash will restore the phone to factory state with nothing on it.
4. 50% Battery Minimum: Do not start with a low battery. If power cuts out during the flash, the device can become unresponsive and much harder to fix.
5. USB Cable and Computer: Use a proper data-transfer USB cable and a Windows PC. Avoid USB hubs, connect directly to the motherboard port for a stable connection.
6. Download and Install Drivers:
   • VCOM Drivers
   • Tecno USB Drivers

Install Stock Firmware on Tecno Phantom 9 AB7

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.

1. Prepare the Flash Files:
   • Go to the download section and grab the firmware package that matches your device.
   • Unzip the file to a folder on your desktop. Avoid using folder names with non-English characters or spaces, the flash tool may not read them correctly.
2. Confirm Driver Setup:
   • The drivers listed in prerequisites need to be installed and working before you connect the phone. If you are not sure, reinstall them and restart your computer.
3. 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.
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 “Download” to kick off the firmware write.
   • Hands off the phone and cable until the tool shows completion. Moving or disconnecting the device mid-flash is the most common cause of a bricked phone.
6. Wait and Reboot:
   • When you see the success message, disconnect the USB cable.
   • Hold the power button to boot the phone. Give it a solid 5 to 8 minutes for the first startup, this is normal.

What to Do if Tecno Phantom 9 AB7 Flash Fails

1. Tecno Phantom 9 AB7 Not Recognized by SP Flash Tool:
   • In most cases this is a driver issue, not a cable issue. Reinstall the VCOM drivers for the AB7, 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.
2. 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.
3. 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.
4. “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.
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 try again. Some MediaTek devices require you to hold Volume Down while plugging in the USB cable to enter BROM mode.
6. 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.

Post-Flash Behavior on Tecno Phantom 9 AB7

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.
• 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.
• 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.
• Be careful when re-adding your Google account, if you did not remove it before flashing, you may see an FRP prompt. Add it fresh during the setup wizard, not afterwards through Settings.
• 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.
• 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.
• 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.

Missing IMEI or Corrupt Baseband on Tecno Phantom 9 AB7 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:

1. 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.
2. 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.
3. 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.
4. 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.

Questions About Tecno Phantom 9 AB7 Firmware

Q1: 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.

Q2: 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.

Q3: 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.

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: Will flashing erase my data?
A: Yes, flashing with SP Flash Tool restores the device to factory state, including Android 9.0 (Pie) 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.

Q6: Is this firmware compatible with other Tecno models?
A: No. This firmware is built specifically for the Tecno Phantom 9 AB7 running on the MediaTek MT6765 Helio P35 chipset. Even variants of the Phantom 9 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.

Q7: 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.

Q8: 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.
