Hi all.

I have a Galaxy Tab 10.1 (2011, WIFI, Model: GT-P7510) which I can only turn on, operate the basics, and turn off.

However, nothing at all happens if I hold the Power and Volume Down buttons (download) nor if I hold the Power button and Volume Up (recovery) buttons.

I think someone in the household where the tablet resided tried to update it and screwed it up. For this reason I didn't want to risk it before but now I myself would like to update it to the latest ROM.

But first things first, I need your help in getting back to Download and Recovery modes.

Thanks in advance
