"If your semi bricked Samsung Galaxy shows this on the screen then you need to get into Download Mode. This jig will get you into Download Mode and save your phone.
If stuck at the boot screen then you need to get into Download Mode. You can use this jig to get into Download

If your phone displays the AT&T logo or shows the logo, reboots and shows the logo, this jig will help you.
