There have been multiple requests lately for service equipment that supports unlock and imei repair on new Samsung Galaxy S5, Note3, Note 3 Neo, Note III LTE, Gear mobile phones such as SM-G900A (AT&T), SM-G900F, SM-G900I, SM-G900K, SM-G900L, SM-G900M, SM-G900P, SM-G900S, SM-G900T, SM-N900X, SM-N900, SM-N9000, SM-N9005, SM-N900A, SM-N900K, SM-N900L, SM-N900Q, SM-N900S, SM-N900T (T-mobile), SM-N900V (Verizon), SM-N900W8
Until recent time none of the service boxes supported this function and the safest way was to buy Samsung codes from Samsung database which still didn't solve the problem of imei repair in case the mobile phone gets blacklisted by the service provider.

With latest update from Z3x team there is a workaround to unlock and change so called super imei or service imei by writing certificate from a similar working phone. Phone doesn't loose signal or 3G/4G network.
