Frequently Asked Questions

Q: Why didn't i get update for Android X On My Phone?

A: Because OEM didn't release that update for our phone, Luckily We can flash "Custom ROMs" For our phone to upgrade it to newer Android Version, Or just Tweak/Mod Current Android Version

Q: Wait Wait, I'm A Noob, What is the meaning of all of those things ( Custom ROMs , Flashing , OEM , Tweak) ?

Dev:

Developer:

A man or woman who create (develop) software.

ROM:

1. A modified version of the Android operating system.

2. Read Only memory, Means that it can be modified with Difficulty or not Modified at All

AOSP:

Android Open Source Project, a project by Google. Its Basically Android System without any modifications , The Open Source Part means that any Developer can modify it and use it and share it ( as long as he don't gain money from it )

CM:

CyanogenMod:

A free open-source project based on the AOSP. It is a Modified Version of android.

Firmware:

a piece of software to make hardware function correctly. This can refer to Radio Firmware, but is normally used as another name for ROM made by certain Company

Stock:

Means unmodified Version of something ( Like: i Flashed Stock TouchWiz ROM )

Radio:

1. (don't confuse with Radio Firmware) A piece of hardware that allows communication. There are 3 main radios in your phone. Bluetooth, WiFi and GSM/CDMA.

2. The lowest part of software layer is the radio: this is the very first thing that runs, just before the bootloader. It control all wireless communication like GSM Antenna, GPS etc.

Radio Firmware:

type of software that allows correct communication with the radio and the operating system. A newer firmware would normally improve battery life and call quality. The radio firmware only applies to the CDMA/GSM radio.

CDMA/GSM:

A type of network communication between phones and carriers. GSM phones normally are included with SIM Cards that authorize them onto the network. CDMA have this authorization built in and do not need a sim card.

Bootloader :

The bootloader is code that is executed before any Operating System starts to run. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment. Think of the bootloader as a security checkpoint for all those partitions. Because if you’re able to swap out what’s on those partitions, you’re able to break things if you don’t know what you’re doing. So basically it commands the kernel of your device to Boot the Device properly without any issues. So careful with bootloader since it can mess things very badly.

Kernel :

A kernel is critical component of the Android and all operating systems. It can be seen as a sort of bridge between the applications and the actual hardware of a device. Android devices use the Linux kernel, but it's not the exact same kernel other Linux-based operating systems use. There's a lot of Android specific code built in, and Google's Android kernel maintainers have their work cut out for them. OEMs have to contribute as well, because they need to develop hardware drivers for the parts they're using for the kernel version they're using. This is why it takes a while for independent Android developers and hackers to port new versions to older devices and get everything working. Drivers written to work with the Gingerbread kernel on a phone won't necessarily work with the Ice Cream Sandwich kernel. And that's important, because one of the kernel's main functions is to control the hardware. It's a whole lot of source code, with more options while building it than you can imagine, but in the end it's just the intermediary between the hardware and the software. So basically if any instruction is given to mobile it first gives the command to kernel for the particular task execution.

Recovery :

Recovery is defined in simple terms as a source of backup. Whenever your phone firmware is corrupted, the recovery does the job in helping you to restore or repair your faulty or buggy firmware into working condition. It is also used for flashing the Rom’s , kernel and many more things.

to access it press Volume Up + Home Button + Power Button in the same time.

Flash:

To Install Something(ROM/Mod/GApps) From Recovery/Odin

Odin:

A leaked Tool ( From Samsung ) to flash something ( Mostly Stock Firmware ) to your phone ( but its limited unlike recovery ) and uses download mode to flash

Download Mode:

Its only i samsung devices and its the mode that Odin uses to flash anything.

to access it turn off your phone then press Volume down , Home Button , Power Button in the same time

Bootloop:

Means that something goes wrong while booting the phone so it tries to boot up correctly again and again in a loop.

Brick:

When your mobile is unusable and its Just like a "brick", There is Two types of "Bricks"

1. Soft-Brick:

When you can recover your mobile Easily

2. Hard-Brick:

When you can recover your phone but not easily and Sometimes when you can't recover it

Nandroid Backup:

A Backup Usually made by recovery, And Usually Contains Backups for /system and /data partitions.

Modification:

Mod:

A modification to a part of the phones software. It is also POSSIBLE to mod the phones hardware but is not recommended.

Modding:

To make mod

Modded:

To have mods included in something

Governor:

A system embedded into the kernel to automatically change the current working CPU frequency depending on the workload. It would only go up to what it is overclocked (or underclocked) to, this is called the maximum frequency. It would not drop bellow the (just as easily configurable) minimum frequency.

Overclock:

(don't confuse it with underclock) to exceed the default maximum CPU speed. This could make a phone more powerful but may cause damage. Although no damaged has been reported so far it could still drain battery life.

Underclock:

to change your phones maximum frequency to LOWER than the default to attempt to extend the phones lifespan and battery.

Library's/Libs:

a set of instructions for applications to use to function. A functioning camera lib would allow the camera to be used.

Logcat:

A logging system built into the ADB

ADB:

"Android Debug Bridge" a system that can be accessed using a computer where you can manage the device from. You need the Android SDK to use it.

SDK:

"Software Development Kit" a set of tools used for software development.

WIP:

"Work In Progress"

JDK:

"Java Development Kit" an SDK for the java platform. It is needed to run the Android SDK.

JRE:

"Java Runtime Environment" a collection of binarys and files to allow java software to execute.

Execute:

To "run" or "start" a binary

Binary:

(sometimes called bin's) a group of executable files.

Q: Can I easily Brick My Phone ?

A. Yes, However Most of the time its recoverable

And As long as you read the OP And make Sure that the thing that you are going to flash is compatible with your phone You won't brick it "alot" .

Q: So Now What should i begin with ?

A. Firstly, You should know about "Flash Counter".

The flash counter is a binary counter built in Samsung phones that is used by Samsung to basically help identify if you have been tampering with your firmware and flashing unofficial software.

Remember Odin that we talked About in the Third Question?

Each time you flash unofficial firmware via Odin, your binary flash counter goes up by 1.

Q: is there is anyway to bypass that ?

A: No, You can't bypass it, But Odin has a built-in feature to reset the counter "Force Reset Time".

And/or you can use Triangle Away App by Chainfire to Reset it.

Q: How can I Flash Via Odin?

A: Refer To Post #2

Q: So What should i learn next?

A: What is EFS , How to Back it up And How important this Folder is.

You will Find Alot of information about EFS Here

Q: How Can I install A Custom Recovery ?

A: Refer to Post #2

Q: What Can I do with A Custom Recovery ?

A: Make a NANDROID backup of your current setup and restore that backup!

Flash ROMs, modems, kernels, themes, etc.

Wipe data, clear cache, etc.

Q: My Phone is Bootloop-ing After Flashing Stock Firmware Via Odin What Should I Do

A: Boot To Recovery

Wipe Data and Cache

Reboot
