How to make iOS 17 update compatible on iPhone X?

1. This is a user to user forum, Apple is not here, only other users like yourself.
2. No, the iPhone X lacks the hardware, RAM and CPU to run iOS 17. Nobody can wave a magic wand and make it run on it.
3. Apple will not go back and support a vintage device like the iPhone X.
4. If you need a newer iOS version, get a newer iPhone, does not have to be a brand new one. Anything from an iPhone XS onward will support iOS 18.

You don't! Software has always outpaced Hardware ever since the very first computer. Devices will not be able to take advantage of the advancements in the Software when the Hardware on the device is fixed and not capable of supporting these advancements.
