Hello guys

I went today to purchase new s4 lte. The store had to wait for the stock to arrive, because they were out of my preferred color.
So, I went for lunch to kill some time, while waiting. Meantime, the staff collected the device and took liberty to set it up for me, and install bunch of apps.

Long story short. I remove all the junk and proceeded to Wipe Partition in recovery. But whenever I try, it say Error, and boots the device. Not like it matters that much, but I'm able to do that with my s3 and note 2 without problem. Just the s4 seem to throw Error while wiping partition.

Anyone experience that?

Thanks for reading
Seba
