What's the difference between root and unlock/lock?

Hello i would just like to ask what's the difference between root and unlock/lock?
For a specific reason i am trying to install a premium game (a cracked APK file from apkmania.com) and it requires for a Lucky patcher of the game so that it's license verification will be somewhat disappear, and when i was browsing about that lucky patcher it says that i need to have a rooted device, so can i do a root of my device without unlocking it?
Also my phone's build number is 11.0.A.5.5 Sony Xperia Miro and this thread (http://forum.xda-developers.com/showthread.php?t=2014188) says that my phone should be rooted on a 11.0.A.1.0 firmware but my phone is not rooted on that build number because once i purchased my Sony Xperia Miro i immediately upgraded it to 11.0.A.5.5
Now my question is how can i downgrade my phone to 11.0.A.1.0 firmware so that i can root it then upgrade it to 11.0.A.5.5 then root it again thanks

Maybe you should try to root it with some other method first. If you want to go back to previous version, just flash that version instead. Maybe you should try srs root, a new unlockroot style program.

You can root your Miro on 11.0.A.5.5 without rooting on any other firmware, download unlockroot and use that. I used it on my Miro what shipped with 11.0.A.5.5.

download 11.0.A.1.0 firmware( ftf file) . download flashtool! flash it using flashtool!

[Q] need help on unlocking my st15i pls help ( tried all tutorials)

hello guys i need a little help. i am using sony xperia 2011 device which is xperia mini st15i.
its rooted with eroot on stock rom and stock kernel with locked bootloader.
i wanted to install cwm mod on my phone but i found that i cant install cwm on my device as my stock kernel does not have recovery partition and i dont want to unlock my bootloader atm. i tried xparts and xdaromhub to install cwm on my device without unlocking bl but none of the method seems to be working for me. now i am thinking to go ahead and unlocking my bl and install a custom kernel but i want to know is there any method by which i cam backup my current state of my phone i.e. in future if i want to revert back to stock rom and stock kernel with bootloader locked like it was never unlocked. if there is a method for that please tell me or if u know any other method of installing cwm without unlocking bl pls tell me that too. also i have a backup of my stock firmware from pc companion which i made .ftf file with flashtool. i have flashed it successfully in past so will that firmware relock my bootloader and revert to stock kernel and stock rom if i flash it with flashtool after unlocking bl? any help would be greatly appreciated. thank you so much for reading

I just rooted my Z3. its fairly simple. Follow the Guide here.

to summarize, what you need to do is as follows:
1. Downgrade to Android 4.4.4
2. Root the phone
3. Update back to Android 5.1.1 using pre-rooted roms
All tools, detail step by step is at the link i shared above. worked for me.
