Unable to select "wipe data/factory reset" in recovery mode A coworker asked me if I could fix her Samsung Galaxy Note Tab 3, due to her daughter locking the device and not being able to unlock it. I'm an iOS guy but since I'm in the IT department I decided to give it a try, and I looked up how to reset this device to factory settings. 

I am able to enter in recovery mode, and I have several options. The one I want, "wipe data/factory reset﻿", is not able to be selected, since the highlighted option in the menu jumps from the  item before it to the item after it. In fact, if for example the option is the number 3, I press the volume down key oen time and the highlighted option changes from the 1st item to the 2nd, but if I press again it does nothing. If I press again, it jumps to the 4th item, not giving me the option.

I don't know if this is because of the device, because of Android, or it's just me being ignorant. If any of you could help me out it'll be wonderful.

Thanks a lot.
I know this answer may be of low quality, having no concrete explanation and all; but sometimes recoveries behave pretty weirdly. Once with my old device, I tried to make a Nandroid backup, and it completed within a few seconds. Seeing that the backup was basically empty, I ran it again, and this time I can't select the nandroid option.

You can try what I did - just select the option with your volume keys as though it's there. Just guide yourself with the highlight.
