It sounds to me like you just downloaded Safestrap and just let it sit on your phone, not actually installing it. So here we go, I'll give you a step by step run down of how to get this up and running on your phone.
1. Root your phone using Razr's Edge.
2. Verify that your phone is set up to install apps from Unknown Sources.
3. Download Safestrap.
4. Browse to the downloaded Safestrap file using a file manager, open it and install it.
5. After that, open Safestrap up like you would a normal app on your phone.
6. Go through the disclaimer. From there, click on "Install Recovery". When it's completed, the status will say "Installed" on it.

7. Verify that the Eclipse .zip file is on your actual SD Card (in the "sdcard-ext" directory).
8. Power down your phone and reboot like normal.

9. On boot up, you'll see a new splash screen asking if you want to run Safestrap (Menu Recovery) or "Continue" with regular boot up. Select the Menu for Recovery option.
10. Once in Safestrap, click on "Boot Options".
11. Click on rom-slot1, select the size of your partition (if you like to keep apps "internally, select a larger size), then click on Create ROM Slot.
12. Once rom-slot1 has been created, click on the "Activate" button to set it as the active boot partition.
13. Now go back to the main Safestrap menu and this time click on "Wipe". From there wipe your "Cache" and "Dalvik Cache". This will not erase any of your settings or files.
14. Go back to the main menu and this time click on "Install". Navigate to your Eclipse .zip file and select it. This will take awhile.
15. Once Eclipse has been installed, go back to the menu, wipe your two caches again (redundant, I know, but I'm paranoid about the havoc of not wiping cache enough when flashing).
16. Select the reboot option on the main menu, select "System" and it will restart your phone. When the Safestrap menu pops up this time, simply hit "Continue".
17. Voila, your phone will now have Eclipse. NOTE: The first boot up takes FOREVER, so just have some patience.
Also note that this is basically a separate operating system from your main partition. You'll need to reinstall apps, sync contacts, restore text messages, and all of that jazz as if you had done a Factory Data Reset.
