*#*#3646633#*#*

However, that is the generic MediaTek engineering code. SPD has its own. Depending on the brand and Android version (Go Edition, Android 10/11/12 Go), the codes vary.

Here are the actual SPD-specific engineering codes used for IMEI repair:

| Function | Dialer Code | Works On | | :--- | :--- | :--- | | SPD Engineering Mode | *#*#83781#*#* | Most Tecno, Itel, Infinix (Android 7-11) | | Factory Test Mode | *#*#3646633#*#* | Some SPD variants (cloned from MTK) | | Unisoc Engineering Mode | *#*#2580#*#* or *#*#958#*#* | Newer Unisoc (SC9863, T606, T610) | | Debug & Test | *#*#889#*#* | Older SPD SC7715, SC6820 | | ZTE/Blade specific | *#*#983#*#* | ZTE phones with SPD chipset |

Important Note: These codes do not magically generate a new IMEI. They open a secret menu where a specific tool called "Connectivity" or "CDS Information" allows you to write the IMEI manually.
