For devices powered by Spreadtrum (SPD) or UNISOC chipsets, "IMEI repair" refers to restoring the original factory identity of a device after software corruption (often shown as "Invalid IMEI" or "Null"). 🛠️ Common SPD Engineering Mode Codes
You can often access hidden menus on SPD-based Android devices to check hardware status or restore connectivity settings using these dialer codes: Standard Engineering Mode *#*#83781#*#* Alternative Engineering Mode *#*#3646633#*#* Direct IMEI Menu (Specific Models) *#*#46349#*#* General Information *#*#4636#*#* Check Current IMEI 💻 Professional Repair via PC Tools
For modern SPD/UNISOC Android devices, dialer codes alone often cannot rewrite the IMEI due to security locks. Technicians typically use the WriteIMEI Tool
The air in the cramped workshop smelled of solder and old lithium batteries. On the workbench sat a sleek but silent Infinix phone, its screen flashing a dreaded message: Invalid IMEI. For its owner, it was just a paperweight. For Leo, the local tech wizard, it was a puzzle.
Leo knew that Spreadtrum (SPD) chipsets could be finicky. He reached for his reliable Toolkit, knowing the first step wasn't a physical tool, but a digital one. He tried the "old school" approach first, tapping a series of symbols into the dialer.
"If you're lucky," Leo muttered, "*#*#46347#*#* will open the door".
The screen flickered. A hidden menu—the Engineer Mode—revealed itself. This was the "code" many sought, a back door into the phone’s most sensitive hardware settings. However, the software was stubborn. The "Invalid" status remained, likely caused by a corrupted partition during a previous update.
Leo shifted to his PC. He launched the SPD Write IMEI Tool, a specialized program designed for UniSoc/SPD devices.
"Okay, let's do this the official way," he said, following a precise sequence: spd android imei repair code
Preparation: He sourced the original 15-digit IMEI from the sticker behind the battery.
Connection: He powered off the device and held the Volume Down button while plugging it into the USB port to force it into Diag Mode.
Writing: On the tool, he selected 'Normal Mode,' entered the digits, and hit Write. The status bar on his monitor crawled forward. PASS.
Leo rebooted the phone and typed the universal command: *#06#. The numbers popped up instantly. The signal bars jumped to life, and the workshop was suddenly filled with the chime of incoming messages. The repair was complete.
If you entered *#*#83781#*#* and nothing happens, or the AT command returns ERROR instead of OK, you are facing one of three problems:
Summary: There is no dialer code to repair an SPD IMEI. You must use a PC software tool to write the IMEI via the diagnostic port.

Warning: modifying or rewriting IMEI is illegal in many countries. Only repair or restore an original IMEI for devices you own or are authorized to service. Proceed carefully and always back up before making changes.
On older SPD (Spreadtrum) Android chipsets, people sometimes refer to:
*#*#3646633#*#* or *#*#83781#*#*) → but these do not directly repair IMEI.On some very old SPD phones (SC6531, SC7715 feature phones or Android 2.3):

You cannot write an IMEI using dialer codes. Security Devices: Newer SPD chips (Unisoc) have strict
