After several weeks of using windows phone 7, I really cannot stand using this phone without custom ringtones.. they built-in ringtone is really bad..
But I’ll touch on that subject later. First, let me guide everyone through unlocking your Windows Phone 7. I tested it on my LG Optimus 7 E900. And no problems occur.
Background : This works on my system, Windows 7 Home Premium 32bit System and LG Optimus 7.
First of all, this is a list of tools you will need.
1. Zune Software (http://www.zune.net/en-US/products/software/download/default.htm)
2. Chevron WP7 Software [Link Removed]
3. Chevron WP7 Cert [Link Removed]
4. Windows Phone 7 SDK (http://create.msdn.com/en-us/home/getting_started)
Step 1: Install Zune Software on your PC
Step 2: Install Windows Phone 7 SDK
Step 3: Email Chevron WP7 Cert (The Cert File itself, and not the zip file) to your own email address linked to your Windows Phone 7
Step 4: Open the Chevron WP7 Cert file from your phone to install it to your phone
Step 5: *Restart your phone*
Step 6: Connect your phone to your PC via USB. Make sure Zune starts up and can detect your phone properly
Step 7: Disable your phone’s locking screen via settings –> System –> Lock & Wallpaper –> Password –> Off
Step 8: Run Chevron WP7 Software
Step 9: Select both ‘Ensure your phone isn’t PIN-locked’ and ‘Install Certificate blabla..’
Step 10: Click on ‘UNLOCK’
DONE ! !
Troubleshooting: What if I encounter the following screen:
Solution: Make sure it IS connected and that ZUNE is running in the background of your PC and ZUNE can detect your phone.
That’s it.. isn’t it easy? Now I can enjoy an unlocked WP7 device I paid for.
Now your device can handle custom ringtones. My guide on that coming soon.
