Q: ipad isnt syncing onto itunes

If you've "tried all the methods everywhere", then, by definition, there is nothing left to try.

Clearly it would be much more helpful if you told us exactly what you did try.

Similarly, instead of saying "updated software on computer and iPad", you should tell us version numbers.  For example, if you have a Mac and it is running an old version of OS X, or a PC with an old Windows version, you cannot possibly sync your iPad because you need a current version of iTunes that cannot run on these old systems.

Sync your iPhone, iPad, or iPod touch with iTunes on your computer using USB - Apple Support
