How do I fix grey wavy line on start up screen OR other factory reset options?

Hi,

My wife's phone (my old Samsung Galaxy S3) has stopped working today. When it's powered on the screen shows grey wavy lines, see 1st link below.

I've taken out the battery, put it back in again and pressed volume up + the power button and I did get the factory reset screen (see 2nd link below) however it went no further i.e. nothing happened when I pressed the volume down or up button to select one of the options.

I tried replacing the battery with a newer one too. However, now I cannot even get back to the factory reset screen again. So, all I'm seeing now is the grey wavy lines on power up.

I have set-up the phone to save all the important data to the cloud i.e. via a Google account etc. So, I've no problem doing a full factory reset and losing the current data on the phone - if I could get to that option.

Is there any way to resolve this?

Is there another way to do a factory reset other that the way I described above?

Can I "flash the ROM" to reset? How would I do that?


Thanks for your help,

John

To get in to recovery you hold the power up button, the home button, and the power button all at the same time. Release the power button after the Samsung Logo pops up. The you should be able to scroll down to factory rest.
