Jing had developed a special tool, which he called the "IMEI Rescue Master", that could repair and restore the IMEI on these phones. The tool was a small, discreet device that looked like a USB drive, but it was loaded with sophisticated software that could rewrite the phone's IMEI.
But Jing's success didn't go unnoticed. A rival repair shop owner, named Tony, tried to steal Jing's tool and replicate it. Tony offered Jing a large sum of money to buy the IMEI Rescue Master, but Jing refused.
As word of Jing's IMEI repair tool spread, more and more customers came to his shop. There was Mr. Li, who had bought a used phone from a street vendor and needed his IMEI fixed; there was Ms. Chen, who had accidentally deleted her phone's IMEI while trying to upgrade her software.
Wang was amazed. "How did you do that?" he asked Jing.
Jing discreetly took out his IMEI Rescue Master tool and plugged it into his computer. He then connected the phone to the computer and ran the software. Within minutes, the IMEI was restored, and the phone was working perfectly.
