SM-G950U AT&T Android 8.0 new build 8/1/18 question [Answered]

Sorry this is my info from other box, that did not support direct unlock at the moment ( many say only solutions now is flash eng modem first then do unlock via credits ) if octopus box unlock this G950U AT&T android 8.0 ( newest build aug. 1, 2018 ) that no direct read codes unlock ( I know it only can be done with credits and Im ok with that ) I will buy credits from octopus if this can be unlock ( without any eng modem flashing needed ) because customer do not want to loss data, and with eng modem flash method, for sure it needs to re-flash after unlock using eng modem installation because it might get mess up if I do not do full flash after unlocking ( via eng modem method ) I don't mind buying new credits as long it can be done right. thank you, hope you can answer me asap. By the way I need help on finding my flash file. to be able to work again
