Ok. Let me talk you through this like you are downloading from the phone.
I must recommend that everyone backup before installing new software. Its the safest way to fly.
1. Open Opera browser. In the address bar, type
http://tinyurl.com/c5w5bd and navigate to this page.
2.Above the file icon is a download link. Tap this. Its going to ask you to open, save, cancel. Choose save. Leave the name as it is. Folder as none. Location, rap drop down box and choose My Storage. Tap Save.
3. Double tap the "Green" checkmark to start installing. It may ask you where to install, but I don't think so. If it does, choose Device. Once its done, it will tell you to restart.
Tap ok at the bottom left, and it will restart for you.
That should be it.
If you have troubles, let me know.
