I recently came across a concerning post on Facebook that claims to offer IMEI repair services for Samsung blacklist or nonpayment phones. This caught my attention, and I decided to reach out to the individual who made the post. They mentioned using a tool called USB Redi
rector and Z Tool to successfully repair the IMEI of a test phone.

ON Backside as you they are using GSPN.

I am concerned about the security implications of this discovery and believe that Samsung should take immediate action to address this vulnerability. The ability to easily change a phone's IMEI could have serious consequences, including the potential for nonpayment phones or stolen devices to evade detection.

Samsung can block the IMEI, but they can spoof and install a fake signature inside the phone, so Samsung can't do much.

here are logs if need more

I am writing to bring to your attention an urgent matter regarding the illegal use of GSPN by certain individuals. It has come to our attention that some users are exploiting vulnerabilities in the GSPN system, particularly those involving Vietnam and Chinese factory accounts. These individuals are able to generate Em tokens, repair IMEI numbers, and perform unauthorized unlocks.

This poses a significant security risk to our organization and requires immediate action. I have attached the relevant logs that may assist in identifying and apprehending the perpetrators.

I kindly request that the appropriate measures be taken to address this issue and enhance the security of our GSPN system.

Thank you for your prompt attention to this matter.

Best regards,
