1. Get your Mopho, download "Root Check" from the Android Market.
2. Go to your computer, click start, then computer, then system properties, here you will see whether you have a 32-bit operating system or a 64-bit operating system (you need to download 2 things to use One Click Root: 32 or 64 bit driver depending on what you find here and then the One Click Root file).
3. Now go to:
Photon AIO One Click Root
(this is the link where the 2 downloads are located and the link you will see used in the video below).
4. Watch this video through once or twice to get a feel for what you will be doing and then follow every step you see in it:
How to root the Motorola Photon 4G and get Free Wifi Wireless Hotspot - YouTube
(The video moves a bit quick and I found a few differences between my computer and the video. Here are my tips: after you download the 32 or 64 bit driver and One Click Root, go to start, then computer, then downloads, right click the driver and "extract all" to the desktop (you'll see it creates an icon on the desktop, do the same for the One Click Root). In the video he double clicks on the extracted One Click Root file and then runs "root.bat" but for me it just said "root")
5. When done run Root Check and it should say you have root. Don't fear the root, embrace it!
6. Let me know how it goes.
