Hello. I own the J7 crown/sm-s767vl. Its a variant of the J737. Looking for info on forcing downgrade from Pie to Oreo.... If its even possible. Also we have the combo fac engineer firmware for it but its binary 4 Oreo just like the Pie is binary 4. Is it possible to find my msl/spc code with the combo fac enginner firmware? I ask because there are logs that it can collect. I appreciate it. Thanks!
