Introduction: The "Null IMEI" Nightmare

Imagine buying a budget Android smartphone based on the Spreadtrum (now Unisoc) chipset—brands like itel, Tecno, Infinix, or certain Lenovo and Samsung models—only to find that you cannot make calls, send texts, or use mobile data. You check your settings, and under "IMEI information," you see dreaded words: "Null" or "Unknown."

This is a common firmware glitch in SPD (Spreadtrum) processors. When this happens, your phone is essentially a mini-tablet with no cellular function. The solution? An SPD Android IMEI repair code.

Unlike Qualcomm or MediaTek chips, SPD devices have a unique, code-based repair system that doesn't always require a PC. In this 2,500+ word guide, we will explore everything you need to know about SPD IMEI repair codes, how to use them, the risks involved, and the professional tools required when codes aren't enough.

This is the most reliable "code-only" method for SPD chips.

Step 1: Open the Dialer Open your phone's stock dialer app (like you're making a call).

Step 2: Enter the SPD Engineering Code Type exactly: *#*#83781#*#* Your screen should instantly switch to a white or blue background menu titled "Engineer Mode." If that code doesn't work, try *#*#2580#*#* (for Unisoc).

Step 3: Navigate to "Connectivity" or "CDS" Inside Engineer Mode, swipe left or right. You are looking for a tab labeled:

Step 4: Select "Radio Information" Tap on "Phone 1" (for SIM slot 1) or "Phone 2" (for SIM slot 2).

Step 5: Enter the AT Command You will see a command line with AT+ already written. You need to type the AT command to write the IMEI.

Erase the existing command and type exactly (case sensitive): AT+EGMR=1,7,"YOUR_15_DIGIT_IMEI"

For example: AT+EGMR=1,7,"123456789012345"

Important Variables:

Step 6: Send the Command Tap the "SEND AT COMMAND" button (may say "AT+ SEND" or just "SEND"). You should see a message: OK or /n OK. This means the command was successful.

Step 7: Repeat for Second SIM Go back, select "Phone 2," and enter AT+EGMR=1,10,"SECOND_IMEI".

Step 8: Reboot Power off your phone completely, wait 10 seconds, and turn it back on. Dial *#06# to verify your IMEI has been restored.

Most users search for an engineering code that works like *#*#3646633#*#* (MediaTek). SPD does NOT have a universal IMEI repair code that works via the dialer alone. Any claim that typing *#*#36466#*#* or *#*#83781#*#* will directly write an IMEI is false. Those codes may open engineering mode, but writing requires a secure partition write blocked by Android 7+.

However, older SPD devices (Android 4.4–6.0) had limited access. Let's explore real codes.

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.

There is no magic single-line code to repair IMEI on SPD Android smartphones. The codes listed (*#*#83781#*#*, *#*#3646633#*#*) only open engineering menus for testing — not writing.

For a successful repair:

If you are not a technician, the safest path is to visit an authorized service center. Attempting IMEI repair without proper tools and knowledge often results in a hard-bricked phone (no power, no charging, no detection). spd android imei repair code
