Notes: For convenience with a test vector any input beginning with two hyphens (--) is treated as a comment and output as a header line. An asterisk ('*') at the end of a digit string indicates that a check digit should be calculated. This is most useful for ICCID/LF_EUIMID because it is not always possible for the calculator to determine whether a check digit is included in non-standard ICCID numbers (19 or 20 digits). IMEI codes (14 digit codes with all decimal digits) are treated as hexadecimal numbers when the 18 digit format is calculated. The check digit is, however, calculated using the decimal Luhn algorithm for both 14 and 18 digit formats. The pUIMID for an ICCID is calculated from a 20 digit string. If the input is 18 digits a calculated check digit and a single 'F' digit are added. If the input is 19 digits the last digit is checked to make sure it is a valid check digit and a single 'F' digit is added. If the 19th digit is not a check digit add '*' to the end.

Important Notice

• Its illegal to change your IMEI so you're entirely responsible for how you use this information
  
• In case you don't have the IMEI converter, the algorithm to convert IMEI e.g 108941207520590 to its corresponding HEX 08 1A 80 49 21 70 25 50 09 is 08 *First digit in IMEI*A *Two digits at a time from the rest of the IMEI reversed* . An IMEI like 3596410... would thus go like 08 3A 95 46 01...
  
• In case you don't know the IMEI of the phone the QCN backup was made from, you can search for an IMEI pattern (in Hex Editor) based on the IMEI converter algorithm i.e 08 *A
  
• This procedure is for generic Qualcomm devices and is therefore not guaranteed to work for all Qualcomm devices.
