Tecno Spark Go 2024 (BG6M) Diag Port Not Working?

🛠️ Tecno Spark Go 2024 (BG6M) Diag Port Not Working? Here’s the Real Fix

If you’re working on a Tecno Spark Go 2024, model number BG6M, and suddenly your Diag port isn’t showing, don’t panic. I’ve seen this exact problem during software repair — and after a few headaches and testing, I finally found a solution that works.

🚨 The Real Problem: Diag Port Missing on BG6M

Many people using the BG6M Anti-Crack firmware face an issue where Diag mode just refuses to activate. You connect the phone, open your tool, and… nothing. No port shows up. That means no IMEI repair, no QCN backup, nothing.

This usually happens after flashing or unlocking, especially with anti-crack versions or edited firmware.

✅ Tried and Tested Fixes (Works 100%)

I’ve fixed several BG6M devices with this issue, and here are the two best working solutions using Pandora Tool:

🔁 Method 1: Restore Dump Partition (Most Reliable)

This is the method that saved me the first time. Someone was kind enough to share a working dump of the original partitions, and restoring it brought the Diag port back instantly.

🛠️ Steps:

1. Open Pandora Tool on your PC.
2. Boot the phone into EDL mode (you may need test points or a special cable).
3. Load the dump partition file.
4. Start the restore process.
5. Wait till it finishes, then reboot the phone.

🧩 Method 2: Flash Stock ROM – But Skip a Few Partitions

If restoring the dump doesn’t work for you (or if you prefer a cleaner install), here’s another method. Just flash the official stock ROM — but make sure to skip a few key partitions that may be blocking the Diag function.

🚫 Do NOT flash these partitions:

• NV LTE
• TDFS
• TRANSEC

📋 Steps:

1. Open Pandora Tool.
2. Load the stock ROM.
3. Manually deselect the 3 partitions listed above.
4. Flash the ROM.
5. Reboot the phone and plug it in again.

🧠 Why Skipping Those Partitions Matters

The NV LTE, TDFS, and TRANSEC partitions often carry security or network configs. When flashed, they might block Diag access. Skipping them leaves your baseband and IMEI data untouched — which is key if you’re just fixing port issues.

💬 Final Advice

• Make sure your USB cable and drivers are working fine.
• Always backup the device if it still boots.
• Don’t use random firmware unless it’s been tested.
• This fix has worked on multiple units — both Anti-Crack and standard firmware.
