Re: Having trouble doing a factory reset on my Samsung Mega
Hello. Thanks for registering.
You should have two more options before a reset.
Holding all three buttons for a few seconds while off should bring up a recovery screen, maybe you're emphasising the Power key too much. I don't know where you read about the procedure but I will add a link here.
I have a Note 3 so similar Touchwiz, unless you have a Mega 2 and I don't know much about that, but the Recovery Mode is the same.
Before that, I think what Belodion was alluding to is if you keep trying a password enough times, and this works with mine, you will get a screen saying enter your Username and password, meaning your Gmail address and that password.
The other option has been - though it's been failing people this last week with Lollipop updated devices - is to set a new Lock with a new pin or password using your Google account with Android Device Manager.
You don't need Location on to find it, the remote Lock command will work when the device is on or after it has been turned on again and mobile data /wifi connected.
What am I on about?
It's late here so bear with me. Android Device Manager is normally enabled by default in Samsung Security settings unless you disabled it or using other security.
If you have a pc or Internet access log in to your Google account here

Select Lock, add a real or fake contact number possibly and a return me if found kinda message for the lock screen so you know it has been set. It will ask you to set a new pw/pin.
Use the contact dial button and hang up to bring up the keyboard/ dialpad on the Mega, you can switch between the two.
You may know this already, I don't know.
