I made this as a boot sound. I used the lock.ogg above, and combined it with the "Droid" sound.

To use, move the mp3 using Root Explorer to /system/sounds/power
Rename the stock mp3, delete, or save somewhere else if desired.

EDIT: Got the share link, I think.

Here is one i use Android kills apple lol, MetroPCS_PowerOn.mp3

 

Just tried the link.. It says i don't belong here and try logging on.. I believe if i remember correct there is a public folder and you also need to get the share link..

Edit: Just looked in the public folder and there is a .txt file that contains this;

The Public folder lets you easily share single files in your Dropbox. Any file you put in this folder gets its own Internet link that you can share with others -- even non-Dropbox users!

Step 1: Drop a file into the Public folder.

Step 2: Right-click this file, then choose Dropbox > Copy Public Link. This copies an Internet link to your file that you can paste anywhere: emails, instant messages, blogs, etc.

That's it! To share your file, just send the link to a friend.

 

can you use .mp3 instead of ogg. format?

 

Depends. The boot sound has to be mp3. The lock is ogg. Its how the phone was coded to work. Its a lot easier to just replace the file than rewrite the files
