Spd Android Imei Repair Code May 2026

The Ultimate Guide to SPD Android IMEI Repair Codes

Introduction: The "Null IMEI" Nightmare

For users of smartphones powered by Spreadtrum (now Unisoc) processors, few errors are as frustrating as the "Invalid IMEI" or "Null IMEI" message. Without a valid International Mobile Equipment Identity (IMEI), your device cannot connect to a mobile network for calls or data. This is where SPD Android IMEI repair codes come into play. These engineering commands allow direct access to the device’s radio firmware, offering a software-based solution to restore lost IMEI numbers.

Warning: Tampering with IMEI numbers is illegal in many jurisdictions. This guide is intended only for repairing your device’s original IMEI (which is printed on the box or under the battery). Do not change an IMEI to a number different from the original.

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. spd android imei repair code

Part 1: Engineering Codes for SPD (Spreadtrum) Android

These codes open the Engineering Mode (Engineer Mode) — a hidden menu for hardware testing and parameter modification.

Method: Write IMEI via adb or Terminal Emulator

Requires: Root access + busybox installed.

Code via ADB shell (PC) or terminal (phone): The Ultimate Guide to SPD Android IMEI Repair

su
echo 'AT+EGMR=1,7,"YOUR_IMEI_1"' > /dev/pttycmd1
echo 'AT+EGMR=1,10,"YOUR_IMEI_2"' > /dev/pttycmd1

Note: The device path varies. On SPD, it may be /dev/radio or /dev/smd0.

Alternative (using audioserver shell on older SPD):

su
setprop persist.radio.imei YOUR_IMEI
setprop persist.radio.imei2 YOUR_IMEI_2
reboot

Success rate: 60% on SPD Android 7–9; unreliable on 10+. Note: The device path varies

Alternative Codes (If Primary Fails)

Some older or branded SPD phones use different engineering codes:

| Manufacturer / Chipset | Engineering Code | | :--- | :--- | | Older SPD SC7715/SC6820 | *#*#8259001#*#* | | ZTE / Coolpad SPD phones | *#*#6756#*#* | | Generic SPD Android 6.0+ | *#*#83781#*#* | | Nougat & Oreo (SPD) | *#*#3646633#*#* (works) or *#*#558#*#* |

If none of the dialer codes work, you can install Mobileuncle Tools or Engineering Mode Launcher from a trusted APK source (requires root access for some functions).

Procedure using WriteIMEI (Example):

  1. Enable Diag: Use a code from Method 1 to enable the Diagnostic Port on the phone.
  2. Connect: Plug the phone into the PC via USB.
  3. Open Tool: Launch WriteIMEI.exe or your chosen professional tool.
  4. Select Port: The tool should auto-detect the SPD Diagnostic Port.
  5. Enter Data: Input the original IMEI numbers (dual SIM devices require IMEI 1 and IMEI 2).
  6. Write: Click the "Write" or "Start" button.
  7. Reboot: Restart the phone and check if the IMEI sticks by dialing *#06#.
