Tecno Spark Go Plus (BB4k) Official Firmware: Fix Bootloop, Dead Boot & FRP Lock with SP Flash Tool
The Tecno Spark Go Plus (model BB4k) is a budget-friendly entry-level smartphone featuring a 6.52-inch IPS display, MediaTek Helio A22 (MT6761) processor, 2GB RAM, 32GB expandable storage, and Android 9 Pie (Go Edition) with HiOS 5.5.2 customization. Despite its affordability, this device serves millions of users in Africa and Asia seeking reliable basic smartphone functionality.
However, users frequently encounter critical software failures that render the device unusable: continuous bootloops with stuck logos, dead boot conditions requiring forced recovery, Factory Reset Protection (FRP) locks preventing access after factory resets, pattern and PIN removal needs, system UI crashes, failed update corruption, and unknown baseband errors.
These issues typically stem from incomplete software updates, corrupted system partitions, malicious apps, or hardware-level failures affecting the boot sequence. The official stock firmware files represent your definitive solution—these verified factory-signed ROM images directly repair corrupted system partitions, resolve update conflicts, fix bootloader corruption, remove security locks (with complete data erasure), and completely restore your device to its original manufacturer state.
The collection spans firmware versions from V24 (December 2019) to V137 (October 2021), including India regional variants and Global multi-regional builds.

📱 How to Flash Tecno Spark Go Plus (BB4k) Using SP Flash Tool
Quick 5-Step Flashing Process:
- Prepare Your Setup: Extract SP Flash Tool and the firmware (.zip) file to separate folders on your desktop. Install MediaTek USB drivers on your PC. Ensure device battery is 50%+ charged.
- Launch SP Flash Tool: Double-click de>flash_tool.exe to open the application. You will see the flashing interface with “Scatter-Loading” button on the right panel.
- Load Firmware: Click de>Scatter-Loading button, navigate to your extracted firmware folder, select de>Android_scatter.txt, and click Open to load all firmware partitions.
- Uncheck Preloader (CRITICAL): In the partition list, locate and UNCHECK the “Preloader” checkbox. Flashing preloader to incompatible versions causes immediate hard-bricking. Keep all other partitions (Boot, System, Recovery, etc.) checked.
- Start Flashing: Click the green de>Download button (arrow icon) at the bottom. Power off your device completely. Press and hold Volume Down button and connect to PC via USB. SP Flash Tool will detect the device, show a red progress bar, then yellow (flashing in progress). Wait 5-15 minutes without interruption until a green checkmark appears. Disconnect USB and wait 5-10 minutes for device to fully boot.

Frequently Asked Questions (FAQs)
Which firmware version should I download for my Tecno Spark Go Plus BB4k?
Choose based on your device region: India users select V94 (latest India build from November 2021 with newest security patches). Global/other region users select V137 (latest worldwide build from October 2021). If you’re unsure of your region, go to Settings → About Phone → check if it displays “India” or region code. Always use the latest version for your region unless experiencing specific issues, in which case downgrade to V92 (September 2021) or V90 (July 2021) as stable fallback builds.
Will flashing firmware remove the FRP (Factory Reset Protection) lock on my BB4k?
Standard firmware flashing via SP Flash Tool may not automatically remove FRP locks on Android 10 builds. After flashing, if FRP is still active, you will need to connect a previously synced Google account. If you don’t remember the account, you may need specialized FRP removal files or professional tools like Miracle Box, CM2, or Tecno service center intervention. FRP is a security feature to protect against theft and cannot always be bypassed with firmware alone.
Can I unbrick a completely dead BB4k device using SP Flash Tool?
Yes, SP Flash Tool is the primary method for unbricking hard-bricked or completely dead BB4k devices. If your device won’t power on, shows no signs of life, or displays constant bootloop, flashing official firmware via SP Flash Tool in Download Mode can revive it. Ensure you have installed MediaTek drivers correctly and follow the steps precisely. If the device still doesn’t respond after attempting firmware flashing, the issue may be hardware-level (damaged charging circuit, battery, or bootloader ROM corruption requiring professional board repair).
Is this firmware safe and officially from Tecno?
Yes, all firmware files listed are official stock ROMs released by Tecno through their firmware update servers. They are digitally signed with Tecno’s manufacturer keys, meaning they have not been tampered with or modified. Flashing official firmware is completely safe and is the recommended method by Tecno for device repair, recovery, and system restoration. Third-party or custom ROMs are not supported by this guide.
Can I downgrade from a newer firmware version (V94) to an older version (V79, V60)?
Yes, you can downgrade to any earlier firmware version using SP Flash Tool. This is useful if a newer version causes bootloop or performance issues. Simply download the older firmware file, load it into SP Flash Tool, uncheck Preloader, and flash as normal. However, note that downgrading may result in FRP lock (you’ll need to enter your Google account credentials to proceed) or temporary data inconsistency. Downgrading from Android 10 to Android 9 Pie (V60 or earlier) may cause app compatibility issues, so use downgrading only for troubleshooting.
