Try following method.
Most likely it will succeed in restoring serial numbers.

Alternate method on Windows:

Changing Serial Number of Dongle by RTL1090

If you have software RTL1090 installed on Windows, you can use it also to change serial number ofthe dongle

Step-1: Open Command Promt, and give command *
C:\rtl1090>rtl1090.exe /eeprom

(My rtl1090.exe is located in folder C:\rtl1090 , that is why I have used this path. You have to use the path in your computer)

Step-2: Click START button on RTL1090 window

Step-3: Set serial number and press Continue button
