Im trying unlock by usb because its new usb dock model and I don't have Rj45 new usb dock model

[profkefah]

ok
do fact unlock with rj45 cable unticked

[Sha]

Yo cannot unlock these models, need a MSL CODE
That is practically impossible
Only One way to get MSL code is authorised Samsung service
and put this code to _MSL.ini file

[profkefah]
