Tutorial for Beginner’s
-Pavan Koli

2. Introduction
•This tutorial will cover the basics to help you understand how to root an
android device.
•We’ll be discussing about Sony, HTC and Samsung smartphones.
•This tutorial will give you a short description of the tools and the methods that
go into the rooting of an android device.
•An overall basic understanding will be achieved by the readers.

3. Common terms to know
•Bootloader – This is like the first thing that’ll run when you’ll start your phone, it
knows the address, in the memory, where the current operating system is
residing and starts execution of the OS and handles the control to it.
•Kernel- It’s the part underlying below the Operating System, or the software,
that interacts with the hardware of the device.
•ROM- It’s none other than the Operating System of the phone, like we have
Windows and Linux the one that you currently use is known as the stock rom,
and other’s like CyanogenMod are referred as custom rom.
•Flashtool- To install custom rom or to install custom kernel(modified kernel) this
tool is used it overwrites the previous OS or kernel, so be careful while flashing.
•Custom Recovery- It can be understood as one spot for all maintenance
related activities, here you can create nandroid backups, clear the cache,
restore from backup. A must have for every android device.
•Brick- There are two types of brick soft brick and hard brick. Soft brick arises
when your phone is not able to start after or during rooting, it’s usually
temporary and can be solved. Whereas hard brick is the state when your
phone won’t be better than a paperweight.

4. Common terms continued
•Nandroid Backup- This is a backup of the current state of your device with all
the settings and all the apps in it. Like a screenshot of the current working
state. Must have a nandroid backup it brings your phone back from the
grave.
•CyanogenMod- It’s a custom rom very smooth, available for everyone, but
be sure to use the stable release. Or be ready to use a device with non
working radio or wifi.
•Custom Kernel-Modified kernel which let’s you extract a lot from your device,
like you can overclock your device, install custom recoveries.
•Overclocking- Increasing the clock speed of your android device, suppose
you have a clock speed of 1 GHz it can be increased upto 1.3 GHz
•Flash mode- The mode you must set your device into before you can use
flashtool to start flashing files. Entering Flashmode depends on the device you
have certain keys are to be pressed to enter this mode, for more info google
flash mode yourdevice
•Bootloop- A state of the device where it just keeps on booting to infinity.

5. There are three steps to follow
**Be sure to first do a factory reset of your device and make a backup of contacts and apps.
1.Unlocking Bootloader --- 2. Rooting the android(Involves many methods) ----- 3. Rooted
Phone(Victory)

6. Tools required
Sony
You’ll need to install flashtool
Unlock Key
It’s ok if you don’t want custom
recovery but it’s recommended
Adnroid SDK
HTC
Nothing as such needed everything is
done using command prompt
Unlock Key
It’s ok if you don’t want custom
recovery but it’s recommended
Android SDK
Samsung
You’ll need Odin
Nothing as such as unlock key is
required
Must have custom recovery
Android SDK

7. Unlocking Bootloader
•In simple language bootloader is locked, with the key with the stock rom of
your phone, so trying to flash different rom will brick it. As the custom rom
doesn’t have the key to unlock.
•So the first priority is to unlock the bootloader, and for that you’ll require a key.
•To get the key log in to the official website of your smartphone brand. Sony
and HTC are the one’s allowing unlocking of bootloader and just follow the
steps listed there to get your key.
•For Samsung android devices there is nothing like an unlock key so those users
can skip this step.
•Now learn how to set your phone in flashmode, google for the model of
phone your having.
•Now just follow the instructions given on the respective sites.

8. RootingSony
You can root either by installing
custom rom, that comes preloaded
with all the su binaries and the
superuser app, or by installing
framaroot.
To install a completely different rom
first you’ll have to modify the kernel to
have custom recovery in your device,
just google for custom recovery for
your device model, choose one’s like
TWRP and CWM. Then flash them
using flashtool. After that copy the
custom rom’s files to the sd card boot
into custom recovery and choose
install from sd card and choose the
copied rom
Or there’s an app called framaroot
that exploits an existing vulnerability in
your device, probably the easiest
method. Also you’ll get to keep the
stock rom
HTC
You can root your HTC device by
installing custom rom. Just before that
you’ll need custom recovery installed.
You can install custom recovery
through commands given through
command prompt, just google for the
commands and you’ll get them.
For the next part copy the
downloaded custom rom onto the sd
card and install it via the custom
recovery.
Samsung
Here you’ll have to go very carefully
as there are not so many resources
available as compared to the other
brands listed here.
You’ll have to use odin to install
recovery.
Also Odin is used to install the custom
rom onto the device, just see that you
get all the right files before flashing or
you’ll end up softbricking your device.

9. Rooted Now What
•A rooted android has immense capabilities, it’s like a mini computer with an
linux Operating System.
•You can install apps like Luckypatcher, Terminal Emulator that’ll transform the
way you phone works
•Rooting is just the beginning the real deal is the actual use that you’ll put your
phone to. You wouldn’t be able to imagine that these kinds of things could
also be done by an android smartphone.
•The capabilities are limitless google what you’ll want from your phone and
you’ll find an app for it.

10. My Overall experience
Sony
The company has supported
unlocking of bootloader and rooting
won’t be much a problem here, but
be ready to troubleshoot some
uncommon problems like bootloop.
HTC
The easiest and most user friendly
when it comes to rooting, the
chances of anything going wrong
can be only a hardware fault like
your sd card.
Samsung
Probably the toughest one to crack
when it comes to rooting, due to lack
of resources and un availability of
large range of tools, these phones
are tough but not impossible to root.
Will power will be tested here
