@dondiego

Have you unlocked the bootloader?

[Thommo]

or because you are rooted your firmware is deemed modified which is another reason for this meesage

[dondiego]

No.my bootloader is locked

[dondiego]

Yes.rooted with kingroot
But with unroot dont correct this issue

[Thommo]

You may have removed root but parts of your firmware will still be modified - you will need to either perform a system repair or a manual flash using Flashtool and a .ftf firmware file
