above is the reason it ended up with an error At this stage msl will not help you to unlock it. Instead you must buy codes it will work if it not hard locked.

u use usb or uart cable?

Do you think FRP can solve the problem?

I guess you already got your answer and frp has nothing to do with msl unlocking :confused:

am so confuse why knox trip can not on this model? so why i suuces on Sc-02h via MSL with knox trip please explain on this?

U have a chance by flashing a combination firmware then try unlock its should work

its not work msl :d
