Click the software boot option to send the temporary bootloader configuration to the device. The phone's state will transition to a specialized servicing mode. Step 5: Perform the IMEI Repair
The International Mobile Equipment Identity (IMEI) number is the unique fingerprint of every mobile phone, allowing networks to identify valid devices and block stolen ones. If your Huawei JNY-LX1 (the P40 Lite) is experiencing issues like "Chip is damaged" errors or shows a null/incorrect IMEI, you may have come across "Sigma" or "SigmaKey" as a potential solution.
) is a technical process typically performed when the device's original identification numbers have been corrupted during software updates or rooting. This procedure requires professional servicing tools, most notably (formerly SigmaBox). Prerequisites and Preparation Before starting, ensure you have the following:
If a technician attempts this process using SigmaKey, the general workflow is as follows: jny-lx1 imei repair sigma
The is powered by the robust HiSilicon Kirin 810 chipset . When a software crash, firmware corruption, or failed flash alters or erases its original identification parameters (resulting in a "Null" or "00000000" IMEI), professional flashing hardware is required. The industry standard for handling this Kirin-based device is SigmaKey (Sigma Plus) .
The IMEI (International Mobile Equipment Identity) is a unique identifier for a mobile device. If an IMEI is corrupted, erased, or null, the device cannot connect to cellular networks, rendering it unusable for calls, SMS, or mobile data.
: A modified USB cable (often called a Harmony TP cable or 150K resistor cable) is required to force the device into Huawei USB COM 1.0 mode. Click the software boot option to send the
: If the phone operates on an older security patch level, use Sigma’s integrated "Software Testpoint" feature inside the tool to force the device into the correct mode without opening the chassis. Step 2: Configure Sigma Software
: Ensure the Android Adapter PCUI and HUAWEI USB COM 1.0 drivers are properly configured on your PC.
In many countries, changing an IMEI number is illegal. Ensure you are only repairing the original IMEI to restore device functionality. If your Huawei JNY-LX1 (the P40 Lite) is
Why IMEI “repair” happens Common legitimate reasons for repairing or restoring IMEI data include:
The software will write the new security data to the NVRAM. Once the process is complete, you will see a "Done" message.
Because the Kirin 810 processor features advanced factory security protocols, standard software commands cannot unlock the bootloader or modify protected partitions on their own. To bypass these restrictions, the phone must be booted into using a physical hardware testpoint.
