I have an Android device (Samsung Galaxy Pocket S5300) which I want to root, because I have used Ubuntu on my PC and notebook for five or six years and I am familiar with doing different maintenance there using root, so I want to have a way to use root-privileges on my smartphone too. I don't have a lot of experience in developing smartphone applications and rooting smartphones, so I need a bit of help.

After a bit of reading, I read that I should download an update.zip file, which I should select in the recovery mode.

I read this thread on XDA Forums where they say I should download an update.zip from MediaFire. I downloaded it to my PC and had a look into it and could find the various binaries that I need to be installed (su, busybox, superuser.apk, etc.)

Now I have a question: do I really need to download an update.zip from MediaFire, where I don't know what it comes from? The reason I'm worried is that I don't know who has created it and have no real possibility to check if the binaries I will execute are not compromised and have no viruses, etc. I am a bit scared to execute binaries somewhere from the web (with root privileges) where I don't know if they are to be trusted and to be sure that they are no viruses, spyware, etc.

Whether the file is on MediaFire or XDA, you still run the risk of a user putting up a bad file (whether maliciously or incompetently). You have to trust someone unless you decide to make your own ROM from scratch.

You could always open the update.zip file and do a cursory look at its contents. And if the poster has a good history, that gives points in their favor. Many posters on XDA host their files on external download tools like MediaFire; it doesn't inherently make the file more suspicious.
