In this part of the video, Stephen addresses the issue of IMEI (International Mobile Equipment Identity) numbers on Chinese phones, referring to them as “ma numbers” for simplicity. He explains that issues with these numbers can lead to SIM cards not working due to blacklisting or duplication, which is common in some Chinese smartphones, especially cloned models like the Galaxy S5. Stephen points out that while changing an IMEI number can be illegal in some countries, recovering a corrupted one, such as after flashing a custom ROM, is typically allowed. He then demonstrates how to check an IMEI number using the dial application (*#06#) and advises that a corrupted number might show a sequence of digits or be all zeros, in which case it needs to be restored. He prefaces that a valid IMEI number is essential for the phone to connect to network providers properly.

In this part of the video, instructions are provided to access developer options on a smartphone by tapping the build number seven times in the ‘About the Phone’ section. This enables USB debugging mode, necessary for recognizing the phone in ADB mode so it can be used with the Antic Adroid Tools for changing the main (IMEI) number. The video also explains how to find the IMEI numbers on the phone, often found on a sticker within the battery compartment or included in the smartphone’s package. After locating and noting these numbers, the next steps include ensuring USB debugging is enabled, having root access, and connecting the phone to a computer with the required ADB drivers and Antic Adroid Tools installed. Detailed steps for installing ADB drivers and troubleshooting connection issues are also discussed.

In this part of the video, the speaker demonstrates the steps to connect a smartphone to a computer and use the MTK Droid Tools for various functions. Key actions include ensuring the phone is set to USB storage mode or MTP mode, running MTK Droid Tools as an administrator, and identifying phone information through the tool. The importance of root access is highlighted, as without it, you cannot change the IMEI number or back up the ROM. The speaker encounters an issue with superuser access, which is resolved by rebooting the smartphone and granting proper root shell access. The correct functioning of the tool is indicated by a green box, and if issues persist, installing a custom recovery may be necessary.

In this part of the video, the presenter guides viewers through the process of adding, backing up, and restoring NVRAM, which is crucial when upgrading or installing a custom ROM on a smartphone. Viewers are instructed to replace the IMEI numbers to avoid issues such as corrupted basebands. The steps include copying the IMEI numbers, replacing them through a specified tool, and rebooting the smartphone to apply changes. Finally, the presenter verifies these changes by dialing a specific code to display the IMEI numbers, ensuring they are valid. The tutorial aims to help users resolve connectivity issues related to IMEI corruption effectively.
