Device driver software was not successfully installed

So I finally reset the device.

I'm stuck on the plug in iTunes screen.

I did moved the backup data to a new drive as you said.

Now I think here's the important thing: When I connected my device to my computer with a USB cable (the guide says that I need to unlock my device but since I'm stuck here I don't think I need to do this), the word "Apple Mobile Device USB Driver" can't be found in Device Manager.

Instead, in "Other devices" section, there are two same line writing "Apple Mobile Device (Recovery Mode)", with an exclamation mark beside them.

So I located the first "Apple Mobile Device USB Driver" in Other Devices and connected them with usbaap64.inf (my system is 64-bit).

In the process, after I clicked on "Let me pick from a list of device drivers on my computer", before the step that I have to clicked on "Have Disk", I got into a page titled "Select your device's type from the list below:", there's just a lot of hardware listed below.

I didn't select anything and clicked next, and clicked on "Have Disk". After I located the usbaap64.inf, clicked on Open then OK, I saw four model on the screen. The first one saying "Apple iPod USB Driver" is highlighted automatically.

I don't think that's right, since I'm using iPhone instead of iPod. So I selected the second model listed, Apple Mobile Device USB Driver and clicked on Next.

Then I received a Update Driver Warning:

Installing this device driver is not recommended because Windows cannot verify that it is compatible with your hardware. If the driver is not compatible, your hardware will not work correctly and your computer might become unstable or stop working completely. Do you want to continue installing this driver?

I clicked on Yes.

Now I saw the "Apple Mobile Device USB Driver" at Universal Serial Bus controllers. I disconnected and reconnected the device as the guide said. I do hear the telltale sound you mentioned, but my iTunes still didn't recognized it.

As I said there's two "Apple Mobile Device USB Driver" before, that is pretty much what I did to the first one.

Now on the second one, I did the exact same thing. But this time, it says "Windows encountered a problem installing the driver software for your device", and there's a line saying "This device cannot start. (Code 10)

Then it is now listed as Apple Mobile Device USB Driver at Universal Serial Bus controllers as well, but with an exclamation mark beside.

Which means that, I got two Apple Mobile Device USB Driver at Universal Serial Bus controllers. One with exclamation mark, one without.

Finally I decided to uninstall the one that has exclamation mark, but it seems it changed nothing at all. I disconnected and reconnected my device again, this message pops out again: Device driver software was not successfully installed.

After this I check on the Device Manager, there is one (*only one this time) Apple Mobile Device (Recovery Mode) listed as Other devices.

What you mean connect Apple Mobile Device (Recovery Mode) to the same device driver as before? Can you show me the steps?

What is Apple's Mobile Device Service? How can I run it?

Yeah I did connect the driver.

I had followed the steps to restart the Apple Mobile Device Service, still the same, iTunes didn't recognize my iPhone.

I tried to call apple support but they are asking me for my serial number which I need to activate my iPhone to check out...
