    I'm a newbie (AKA noobie). Got my Precedent in the middle of Oct. 2011. i was totally new to Android. I thought I was a little bit of a geek, but I couldn't comprehend what looked like gibberish in forum posts about rooting.

    I'm sure there are and will be many more Precedent users who are new to the "Droid." I started this thread to help you.

    I quickly found that I would need to "root" my phone to get the most out of it. But, I still did not fully understand ROMS, shell, NAND locked, flash, etc. I wished I could find simple, I mean a REALLY SIMPLE, set of definitions.

    I finally did, thanks to Nomorefear. I took his list and modified it for new (noobie) Samsung Galaxy Precedent users. I've put a link at the end of this post to Nomorefear's post. Please note that his post has some items specifically for the Optimus phone - you will screw up your Precedent if you use those files/methods. That is the only reason I'm not just giving a link to his good info.

    Again, full credit to Nomorefear, I'm not plagiarizing (stealing) his stuff.

    Here goes:

    "1- Dictionary

    ADB- Android Developers Bridge: The program used to talk to your phone and give it commands (USE IT ONLY IF YOU FEEL COMFORTABLE LEARNING)

    Root/Rooting- Getting the administrative control i.e, "hacking", "jailbreak", etc, etc...... Root is also defined as the base folder of your SD card. If you are told to place a file into root then this is what is meant. REMEMBER-root/rooting-admin control OR base folder on SD card. Please re read instructions you find in the forums throughly so that you may be able to save yourself some time and heartache.

    Superuser- program which gives authority for another program to have Root access. Program examples are "setcpu", "terminal emulator", "auto killer memory optimizer"

    Recovery- a useful tool that allows root users to flash roms, reinstall backups, and do many other fantastic things to help keep your phone from becoming a brick.

    Flash/flashing- the action of "installing" a file that isnt normally installed by conventional means i.e. flashing a rom, flashing a radio, flashing a kernel, etc etc. '/!\ WARNING: flash at your own risk and make sure you have over fifty percent battery and do not interrupt the flashing procedure. YOU HAVE BEEN WARNED!!!!!' :mad:

    Brick- making a device useless so that it is rendered a mass of uselessness i.e. PWNED

    Terminal Emulator- a program which simulates ADB and basically is a way to communicate with the phone and provide a command language that is for upper eschelon (1337) users to helm.

    Nand backup- In your recovery terminal there is an option to make a "Nand backup". This is a restore point or in gaming terms a save point. As most of us gamers know, if you save before you go further in the game and you make a poor choice then you can reset and go back to where you started. This is the same thing but for your phone

    Kernel Easiest way to put it: it is the thing that manages your system resources. This puppeh can help make your phone run better and also overclock it.

    Overclocking Dont worry I wasnt gonna leave this term out. This is written for newbs so lets just say this is the term for making your phone run faster. IMPORTANT NOTE!!! Overclocking your phone too far can make it seize up or go into bootloops if done incorrectly! It can also make your phone run hot. BEWARE!!!!

    PRL Preferred Roaming List: This is just an updated list of what cellphone towers have been added to the system. This means better coverage when updated" - Nomorefear

    Here are some other definitions not covered by Nomorefear. For the following, I give credit to Wiki CMS Groupware (makers, I mean "developers" of Titanium Backup). I've also modified their stuff a bit. Link at end of post.


    system app - A system app is an application that resides in /system/app/ and thus is technically a part of your ROM

    user app - is an application that resides either on the /data partition of your phone's internal memory or on your SD card

    system data - In the vast majority of cases, system data is simply the data that belongs to system apps or services.

    root - is the UNIX system administrator (UNIX is an operating system [OS] just as MicroSoft "Windows" is an OS)

    NAND locked (or "S-ON") device - is a device where the ROM (usually mounted at /system) is write-protected in hardware and thus cannot be modified, even if you have root privileges. Sometimes you get the illusion that you can write to /system, but in any case all changes will disappear after a reboot. This is why these devices often have "temp root" instead of permanent root". In order to get permanent root access, you need to make your device "NAND unlocked" (or "S-OFF") first. In other words, you need to "unlock the bootloader".

    shell - simply is a "command line" to type commands on your Android phone. If you're comfortable with typing on the phone then you can just use the ConnectBot (free) app or the Better Terminal (paid) app. If you want (or need) to type commands from a computer, just install the Android SDK, then enable "USB debugging" on your phone and finally, connect your phone through USB and type "adb shell" on your computer.

    Here is another definition from kejlyCZ (link at end).

    "ROM - is abbreviation for Read Only Memory. In this case, it's the part of the phone software, which is provided by manufacturer (operating system, basic built-in programs) and it's protected from deleting by user. It's the same like when you install Windows, the clean installation with no user data and user installed programs. In Android, ROM means the Android operating system. It can be the official ROM (updated by manufacturer) or unofficial ROM (AKA "Custom ROM) ('brewed' by community,.....

    And FINALLY (unless I edit later):

    Boot Loop or Boot Looping - could not find a definition, but I'm pretty sure it means your phone keeps rebooting endlessly until you turn it off or throw it against the wall!!! Has not happened to me (yet?) but don't think I will like if it happens.

    I hope that gathering all these definitions in one place will help new Precedent users and save you many hours of research and head scratching. :rolleyes:

    Excellent post!

    You're assumption on boot looping is correct, only had it once myself. It is annoying, but easily solved by way of a restore or flashing the ROM again. :)

    Re shell and ADB, if you take a look here: that has a "Mini SDK" which contains ADB/Fastboot which does a lot of the simpler things you need ADB for. It saves the cumbersome SDK download and sometimes complicated install procedure.

    Thank you so much for this post. Very informative and very layman.
    Just had my android phone a month ago so I'm really excited to know more and do more with my phone.
