Tecno Spark 8C KG5k Firmware (Flash File) Drivers, Tools & Guide
Many users struggle with Unisoc devices when selecting the wrong .pac file for flashing, causing errors in SPD Research Tool. This guide solves that problem. You will find the correct firmware, tools, and precise steps right here.
Important: Unisoc firmware comes as a single .pac file, unlike MediaTek’s folder structure. Verify your ZIP contains the .pac file before opening the flash tool. Partial downloads often cause issues.
This page lists 22 firmware builds for the Tecno Spark 8C KG5k, spanning multiple Android versions and security patches. The stock firmware runs Android 11 (Go edition) with HiOS 7.6. Released in 2022, this model may require manual USB driver installation on newer Windows systems.
We verified firmware authenticity across two independent sources. All 22 builds are authentic stock ROMs covering various Android versions for the Tecno Spark 8C KG5k.
Your Tecno Spark 8C KG5k firmware arrives as a compressed ZIP. Extract it using WinRAR or 7-Zip. Check for the .pac file in the extracted folder before proceeding.
A full flash deletes all data: apps, accounts, photos, and settings. This is intentional—it provides a clean slate and resolves issues like screen locks, FRP prompts, bootloops, sluggish performance, and connectivity problems.
Reset Tecno Spark 8C KG5k From Recovery Mode
To factory reset the Tecno Spark 8C KG5k 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 returns the Tecno Spark 8C KG5k to its original factory state. This resolves most software issues including slow performance, app crashes, forgotten screen locks, and bootloops. If problems persist, follow the full firmware flash guide in later sections.
Remove FRP Lock on Tecno Spark 8C KG5k
The fastest method to bypass FRP on the Tecno Spark 8C KG5k is using our free Android apps launcher. After flashing or a reset, you may encounter a Google account lock (FRP). This launcher provides quick access to settings during setup. Always remove Google accounts before flashing to avoid this issue.
When Should You Flash Tecno Spark 8C KG5k?

Which Firmware Version Should I Download?
This is a frequent question. Find your scenario in the table and select the appropriate file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | V245, download this version. It is the latest Tecno Spark 8C KG5k 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 V226, sometimes the latest OTA introduces bugs and an older build performs better. |
| IMEI missing after a previous flash | Re-flash V245 first, then follow the IMEI repair guide. Do not skip the reflash. |
| V245 failed with a flash error | Try V226 instead and double-check your .pac file selection before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | V245, clean state, fresh start. |
For Unisoc devices, start with the latest .pac file. Older SPD Research Tool firmware versions can cause modem issues, resulting in no signal after flashing. Only try an older version if the latest one fails.

Only download firmware compatible with your exact device model. Refer to the firmware selection guide above if you are uncertain.
Important: The Tecno Spark 8C KG5k (KG5k) should not be confused with other Spark 8C variants that may have different chipsets or regional firmware. Even devices in the same Spark 8C line can use completely different processors. Always verify your exact model code “KG5k” in Settings > About Phone before downloading any firmware from this page.
- Confirm your exact model is KG5k, check About Phone, not the marketing name on the box.
- Your device must have a Unisoc Tiger T606 chipset. Boot into recovery mode to verify if unsure.
- Only use files downloaded from this page. Third-party mirrors may serve modified or incomplete packages.
- Compare the file size against the download table. If it does not match, the download is likely corrupt or incomplete.
What You Need Before Flashing Tecno Spark 8C KG5k
Before downloading the Tecno Spark 8C KG5k firmware, complete this checklist. The most common reason Unisoc flashes fail is skipping driver installation. SPD Research Tool requires specific drivers, and Windows may not alert you if they are missing.
- Save Your IMEI Numbers: Dial *#06# in the phone dialer and record both numbers. These identify your device for the cellular network. If flashing erases them, you will need the originals to restore them.
- Disconnect Google Accounts: Remove all Google accounts from the phone before starting. Settings > Accounts > tap each Google account and remove it. This prevents the FRP verification screen after flashing.
- Create a Backup: Copy your data to your computer or an SD card. Flashing replaces the entire software, permanently deleting all personal data, apps, and settings.
- Charge First: Ensure the battery is above 50%. Flashing takes several minutes, and the first boot takes additional time. A power failure during either stage can require advanced recovery.
- Prepare Your PC Connection: Use a Windows computer and a USB cable that supports data transfer. Test the cable first by connecting the phone normally—it should appear in File Explorer.
- Install the Right Drivers:
- Tecno USB Drivers (includes Spreadtrum USB drivers)
Flashing Tecno Spark 8C KG5k Firmware With SPD Research Tool
We use the SPD Research Tool for this process, the standard for Unisoc devices. Always run it as Administrator—right-click the .exe and select “Run as administrator” to prevent permission errors. You can also follow the video guide below.
- Download and Unpack:
- Select the correct firmware version from the downloads above and save it to your PC.
- Extract the ZIP file. If another ZIP is inside the extracted folder, extract that too. You should end up with the actual firmware files, not another archive.
- Driver Check:
- Reinstall the required drivers. Missing drivers are the most common reason SPD Research Tool cannot detect your phone. Reboot your PC after installation.
- Load the Firmware File:
- Click “Load Packet” and navigate to the extracted folder to select the .pac file.
- Connect Your Device:
- Power off your phone completely—sleep mode is not sufficient.
- Connect to your PC via USB cable. The flash tool will detect it automatically.
- Start Flashing:
- Begin the flash by clicking “Start”.
- Leave everything untouched until completion. Even touching the USB cable can interrupt the write and cause a failed flash.
- Wait and Reboot:
- The flash is complete when the tool shows a success indicator. Disconnect your phone.
- Turn the phone on. Do not worry if it stays on the boot logo for several minutes—the system is rebuilding itself.
Video Guide for Flashing
What to Expect After Flashing
These are normal outcomes after a successful flash:
- How to know the flash was successful: SPD Research Tool will display a green “PASSED” message when complete. This confirms success.
- Notification sounds and ringtones return to factory defaults. Any custom tones you had will need to be re-downloaded and re-assigned in 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 as it did when new.
- Stuck in a bootloop after first boot? Enter recovery mode and perform a factory reset—see the hard reset guide above. This can occur occasionally and does not indicate a firmware issue.
- Fingerprint and face unlock data are erased during the flash. You will need to re-register your fingerprints and face data in security settings.
- 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.
- The phone will feel warm during first boot—this is normal. It cools down after a few minutes once the initial app setup completes.
Troubleshooting Tecno Spark 8C KG5k Flash Errors
- Tecno Spark 8C KG5k Not Recognized by SPD Research Tool:
- This is usually a driver issue, not a cable problem. Reinstall the Spreadtrum USB drivers for the KG5k, restart your PC, and try again.
- If the device is still not detected, try a different USB port—USB 2.0 ports work more reliably with Unisoc devices than USB 3.0.
- Temporarily disable your antivirus software—it can sometimes block the Spreadtrum driver from loading without showing an error.
- Boot Loop After Flashing:
- Enter recovery mode and perform a factory reset. This resolves most post-flash bootloops on Unisoc devices. If recovery mode is inaccessible, reflash the firmware from scratch.
- Wrong .pac File Selected for KG5k:
- If SPD Research Tool throws an error immediately after loading the file, you likely selected the wrong firmware. Confirm the .pac file model code matches your Tecno Spark 8C KG5k exactly.
- No Signal After Flashing:
- This usually indicates an IMEI issue. Dial *#06#—if it shows null or unknown, follow the IMEI repair guide before inserting your SIM card.
Missing IMEI or Corrupt Baseband on Tecno Spark 8C KG5k After Flashing?
A missing IMEI after flashing a Unisoc device usually means the NVRAM partition was not written correctly. This happens frequently on SPD devices. The WriteIMEI Tool resolves this for Unisoc chipsets. Ensure you have your original IMEI recorded from before flashing—dial *#06# beforehand. Without the original number, proper restoration is impossible.
Use WriteIMEI Tool for Unisoc to restore it. The video below shows the exact steps.

Questions About Tecno Spark 8C KG5k Firmware
Q1: Will flashing void my warranty?
A: Flashing official stock firmware typically does not void your warranty since you are restoring the device to its factory state. However, some manufacturers may note if the bootloader was unlocked or the flash counter increased. Check your specific warranty terms with Tecno support if concerned.
Q2: 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. Always sign out of Google accounts before flashing to prevent this issue.
Q3: My IMEI shows “unknown” after flashing. Is my phone permanently damaged?
A: No—this is alarming but fixable. Follow the IMEI repair guide above. For Unisoc devices, use the WriteIMEI Tool. 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 occurs offline between your PC and phone via USB. Internet is not required during the flash itself. You will need it later to set up the phone and download apps.
Q5: Can I go back to an older firmware version?
A: Downgrading is possible on most Unisoc devices but not always safe. Some OEMs implement anti-rollback on newer models—if the flash tool throws an error during downgrade, stop. Flashing the same or newer version is safer.
Q6: How long does the flashing process take?
A: The actual flash takes 3-10 minutes depending on firmware size and USB speed. The first boot adds 3-8 minutes. Do not interrupt the device during either stage. If the SPD Research Tool progress bar appears stuck, wait a few more minutes before assuming failure.
Q7: My device is not detected by SPD Research Tool. What should I do?
A: Start with drivers—reinstall Spreadtrum USB drivers, restart your PC, then retry. Switch to a USB 2.0 port if using USB 3.0. Temporarily disable your antivirus. If these steps fail, comment with the exact error message.
Q8: What if the flash fails halfway through?
A: Do not disconnect the phone. Close SPD Research Tool, restart it, and try the flash again from the beginning. Most failures simply require repeating the process. The device usually remains detectable by the flash tool even after a failed attempt.
