Usually as soon as you start entering an expression in the Y= editor
screen, the = sign is highlighted to ensure the drawing of a function.
However, if you have previously used the Transfm application to draw
dynamic graphs, it takes over the graphing functionalities from the
native OS and you can only draw a single graph.
You can skip the next paragraph if you want
The reason is that dynamic graphing needs one or two parameters that can be changed during the graphing process and the graph redrawn with a new value of a parameter, and you end up with a family of curves differing one from the other by the values of one parameters. But since the calculator has space for 10 graphs at most, only one function can be highlighted.
To make a long story short, you must uninstall the Transfrm application from memory. The procedure will not erase it, just kick it out of memory.
Press the [Apps] key. Scroll down or up to reach the Transfm application. Select it and press [ENTER]. If that application was running you will see a new screen that tells you
Graphing functionalities will revert to the native OS
Another potential culprit is the Inequalz App. To uninstall it, do as for the Transfm and select the option that will unload it from memory.

SOURCE: Change TI 84 OS to TI 89 OS??
And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or amazon.com and spare your TI84PLus SE.
