[hytTony]

I will unlock BL on my phone Letv L17 based on MT6769, and before unlock i need to backup. I had tried backup with SP Flash Tool, but no respond when connect phone to compute, maybe it has DA protection.

If i can do these with this tool( mtkclient) ?

Is the question still relevant? I think you should have just tried using the GUI
