Step-by-Step IMEI Repair via Engineering Mode

Dial the code: Open your phone’s dialer and type *#*#3646633#*#*. The engineering mode app will launch automatically.
Navigate to Connectivity: Swipe or scroll to the Connectivity tab.
Enter CDS Information: Tap on CDS Information → Radio Information.
Select Phone 1 (SIM1): Tap on Phone 1.
Enter the AT command:
- Type: AT + EGMR = 1,7, "YOUR_15_DIGIT_IMEI_1"
- Example: AT + EGMR = 1,7, "123456789012345"
- Important: Put the IMEI number inside straight double quotes. Do not add spaces.
Send the command: Tap SEND AT COMMAND. You should see a response: OK.
For SIM2 (Phone 2): Repeat step 4, but choose Phone 2. Use the command:
- AT + EGMR = 1,10, "YOUR_15_DIGIT_IMEI_2"
Reboot: Exit engineering mode and restart your phone. Check your IMEI by dialing *#06#.

Part 6: The Risks of Using SPD IMEI Repair Codes

Before you type that AT+EGMR command, understand the risks.

Permanent Baseband Crash: A wrong syntax (e.g., missing quotes or commas) can crash the modem. You'll see "Baseband Unknown" and no amount of rebooting will fix it.
IMEI Conflict: If you accidentally enter an IMEI already in use by another device (very unlikely, but possible), both phones will be blocked by the network.
Legal Consequences: In the US, the FCC considers IMEI modification (even for repair) a grey area. In India, the Department of Telecommunications (DoT) has arrested individuals for changing IMEI without authorization. Restore the original IMEI only.
Security Backdoors: Entering engineering codes disables some Android security features. After repair, reboot your phone immediately to exit Engineer Mode.

Problem 1: The Code is Blocked by the Carrier/Brand

Manufacturers like Samsung (on their J-series with SPD chips) or modern Android 12+ Go edition phones disable dialer codes for security. The code simply won't work.

Solution: You need a PC-based flashing tool.

Understanding SPD IMEI Repair

Unlike some older MediaTek (MTK) devices where you could use "engineer mode" codes (dialer codes), modern Spreadtrum (SPD) chipsets typically do not support direct IMEI writing via dialer codes. Step-by-Step IMEI Repair via Engineering Mode

If you search for SPD "codes," you will likely only find codes to view the IMEI or enter diagnostic mode, not to change it.

To repair an IMEI on an SPD device, you generally need a Windows PC and specific software tools.

Step-by-Step Professional IMEI Write:

1. SPD Upgrade Tool (ResearchDownload)

This is the official flash tool for Spreadtrum/Unisoc. It doesn't directly write IMEI, but it restores the entire firmware, including the NVRAM.

How it works: You download a "Pac" file (firmware) and flash it. This often resurrects the IMEI automatically.
Risk: Wipes all user data.
