Installing Memtest86+ on an iPhone:

The provided key seems to be a command to install Memtest86+ on an iPhone. However, I must clarify that Memtest86+ is a memory test program designed for desktop computers, not mobile devices like iPhones.

Checking iOS version on an iPhone:

If you're unsure which version of iOS your iPhone is running, you can easily find out by following these steps:

* Press and hold the Home button (if you have an iPhone 8 or earlier) or the Side button (if you have an iPhone X or later).

* Simultaneously press and hold the Sleep/Wake button.

* Release both buttons when you see the Apple logo.

QuickTime Legacy Plug-in Installation:

The QuickTime web browser plug-in is no longer installed by default, but can be added back using the custom setup option in the installer if needed. For Windows Vista or Windows 7, use QuickTime 7, which is specifically designed for these operating systems.

Entering Recovery Mode on iPhone:

If you need to enter recovery mode on an iPhone:

* iPhone 6s or earlier (including iPhone SE '1st generation' and iPod touch '6th generation'):

+ Press and hold both the Home button and the top (or side) button simultaneously.

+ Keep holding them until you see the recovery mode screen.

+ When you see the option to Update or Restore, choose Update.

Please let me know if you have any further questions or concerns!
