Will someone help me make the text visible on this photo, or tell me how to? Please
That's not going to happen, I'm afraid. Samsung 500T is all you're ever going to extract from that image.
Aside from the fact that it was shot in very low light with a flash, which has swamped a lot of it, it's also been sized up & perhaps sharpened from a much smaller image by the looks of it.
This will not gain any information. You cannot create information which is not actually there.
This is what's there, you cannot recreate what isn't.
There might be better information in the original of that photo, but there's none in that particular copy.
The only solution I can see is to take the photo again in good light, & preserve the image resolution.
