Lot of confusion bout d/g b/l is going on.
Read on to know the truth-------->>>>>>

------------------------------->>>>>>

you can use ziphone 2.5c to unlock evry otb.
Just don't press do it all.
Instead go to advanced features and then u can only select downgrade b/l or a,j unlock.
So just select a j unlock.
And press perform actions.

u can also use iplus.
i don't much bout iplus.
But ziphone rocks.

If you found this knowledgable.
