Before And After Android Rooting Some Technical Terms Geeks Should Know For Your Device CuStomization

ART[Android Runtime]{Recently Known Dalvik cache}

Usually Android Programs are written in Java, then converted to Java machine compatible code , which are finally converted to Dalvik compatible files, before installing into the Android device...thus Dalvik is been used till date for the running of apps.. It was introduced in Android 4.4 [Kit-kat]and has completely taken over in Android 5.0. Threre much more available but I don't want to go inside it but ART is said to improve battery life and app performance, amongst others. For Technical detail you may Go Wikipedia link.

Bootloader

A bootloader is a computer program that loads an operating system (OS) or runtime environment for the computer after completion of the self-tests. The Bootloader is your phone’s software foundation. It’s basically what runs before your operating system starts (like a PC’s BIOS). As many manufactures don’t want you to modify your phone’s OS, it needs to be unlocked before you are able to root your
phone or install custom ROMs.

Brick

This is Like worst Dream Of Every Android Geek. Like the name already implies, a bricked phone (or tablet) can only be used as a paperweight or nice decoration for your apartment. Bricked devices are irreversibly damaged and won’t work anymore. This can, for instance, happen if damaged ROMs are installed or wrong firmwares are flashed. Always make sure to read instructions and verify checksums (a set of numbers that identify the file) to make sure nothing goes wrong. If you’re lucky and your device is only soft-bricked, meaning that it does not boot but still turns on, you might be able to Start it.

BusyBox

Android is being based on Linux/Unix System, offers a limited amount of UNIX commands (which most users won’t need anyways). BusyBox will implement more commands that are necessary for some root apps to work properly.You May Download from Google Play Store

Custom ROM

This is favorite Part Of Geeks .a custom rom improves Device Capability A custom ROM is a modified version of the Android operating system. Tweaks, additional features, different themes or an enhanced performance are usually included. Custom ROMs also offer the possibility to use a newer, unreleased, version of Android on your phone that might usually not be available for your device because of restrictions from manufacturer or providers.

Dalvik

Dalvik is a virtual machine that processes Android app code. Consequently, it is responsible for translating app code into actions on your Android device.

Fastboot

Fastboot is a diagnostic- and engineering tool which offers you several features such as launching in recovery mode or flashing image files.

Kernel

The kernel is the brain of your phone that controls how the system and hardware interact. It’s basically the lowest level of your operating system that manages memory and hardware.

NAND partition

NAND stands for “Negated AND” or “NOT AND” and describes the hard drive partition that stores all system relevant information like the bootloader, recovery mode or the kernel.

NANDroid backup

It is Complete Backup of your android systemsThis backup can be restored later and might save your phone after flashing a faulty ROM or theme.

Radio

the radio helps us communicate with other i.e We Can Call The radio is responsible for sending and receiving voice and data. Using an optimized radio can improve your phone’s reception or increase battery life.

Recovery Mode

Recovery mode offers you the possibility to perform system-level tasks (like formatting, defragmenting, etc.), backing-up your devices or install custom ROMs. Android offers a limited stock recovery function. More sophisticated recoveries like ClockworkMod Recovery and TWRP Recovery offer additional features and are easier to use.

Android Rooting

will give you full administrator access of your device. It might also void your warranty (depending on the device and your place of residence), so make sure to handle your device with care after rooting it. You are always able to revert this process by simply flashing a stock-ROM (the original ROM installed by your phone’s manufacturer). Doing this will also “restore” your warranty.

S-OFF

S-OFF means that the NAND partition of your Android device is unlocked. This mostly applies to HTC phones.

Superuser

Rooting your phone will create a new “account” with complete administrative permissions. This superuser account is used by some apps and functions.

Xposed Framework

it support additional functionality to your Device. It currently does not work on devices running Android 5.0 because it requires the Dalvik cache which has been replaced by ART.

How to Fully Backup Your Device Without Root

If your Android device is not rooted yet, you won’t be able to perform NANDroid backups. I wouldn’t suggest to root your tablet or phone without having a proper backup, because there is always a chance of error . ABD Backup-let’s you create a full backup of your device without root access and is the perfect solution for users without root access. The free program also offers a restore function and runs on Windows and Linux.

Custom Recovery Mode

The standard Android recovery mode is very limited and does not offer many features. That’s where replacement recoveries like Team Win Recovery Project (TWRP) and ClockworkMod Recovery (CWRM) come in place. They offer the possibility to flash custom ROMs which is not possible with the stock recovery mode. Other features include a file browser for update.zips, adb shell and NANDroid backups. Without a custom recovery you won’t be able to flash a custom ROM. It does not really matter which replacement recovery you install, just go with the one that suits you most. In some rare cases the root script or custom ROM installation only works with either TWRP or CWM. While CWM was pretty much king in the last year, TWRP has taken over and would be my suggestion to go with.

TWRP – Team Win Recovery Project

custom recovery offers an easy and touch driven user interface. It includes all typical recovery features needed to install custom ROMs, kernels, other tweaks and many more. You are also able to backup and restore your device using TWRP.

CWM – Clockworkmod Recovery

is one of the most popular custom recovery modes. It also includes all advanced recovery features like installing custom ROMs and other files, as well as a backup and restore function. You can control the CWM UI via touch or key-input.

Understanding Custom ROM Versions

As Custom ROMs are constantly improved, they usually come in four different categories: Nightly, Milestone, Release Candidate and Stable. This is what you can expect in every stage:

Nightly

Nightly versions are usually generated every 24 hours and can be highly experimental and unstable. Especially early versions of a new custom ROM can have many bugs and missing features. If you want to have the latest features while risking instability – go for nightlies!

Milestone Snapshot

Milestone Snapshots are basically nightly versions that have reached a certain milestone. They can be regarded as being quite stable, but may include certain bugs and issues. Since they are only created every few weeks (or months), they won’t have the latest features that might be included in the nightly versions. If you are looking for the latest features while having a rather stable system, check out milestone snapshots.

Release Candidate

Release candidates, as the name already implies, are one of the last builds before the stable version of a custom ROM is released. RCs are mostly stable but might have a few minor issues. If you’re looking for something stable and ready for daily use, I would recommend to go with release candidates!

Stable

Stable versions are (obviously) the most stable versions around, with all or nearly all problems fixed. Some stable ROMs may still include some smaller issues or certain things not working. Stable versions are definitely the safest way to go, but it might take months before a new stable with new features or fixes is released.

Official, Unofficial & Combined Releases

It is also important to say that custom ROMs are often available as official and unofficial releases. Later use the source code of the official release (if publicly available) and adapt it to devices not supported by the main developers. Unfortunately, this often leads to a delay. In addition to that, many developers combine features of different custom ROMs Like Xda
