Decided to post this for anyone that is curious and wants to know the terminology used in these roms.
I take NO CREDIT for this, just wanted to share my findings. Source below. Let me know if I missed any.
http://wiki.cyanogenmod.com/index.php/Terminology
http://www.addictivetips.com/mobile/what-is-odex-and-deodex-in-android-complete-guide/
TERMINOLOGY -
*CWR aka ClockworkMod Recovery-
A custom recovery for Android phones and tablets that allows you to perform several advanced recovery, restoration, installation and maintenance operations on your Android device that aren’t possible with the stock recovery.
*Superuser-
A progam which gives unlimited access privileges to perform any or all operations on the operating system.
*KIES mini-
Kies Mini is an official application from Samsung that is used to update the software on your phone. It should not be confused with the full Kies application, which has a lot more functionality and is not officially supported in the USA. Therefore, abbreviating "Kies Mini" as just "Kies" can cause confusion.
*ODIN-
Odin is the Samsung software used to update Samsung phones. It does not work with any other devices other than official Samsung phones.
*OTA or FOTA-
(F)OTA stands for (Firmware) Over The Air and is the process by which required updates and enhancements to your phone's basic operating system can be sent to you through the cellular network. The Galaxy S II software update will be sent via FOTA and is available through Samsung Kies mini.0
*ODEX-
In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These ‘odex’ files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.
*DEODEX-
Deodexing is basically repackaging of these APKs in a certain way, such that they are reassembled into classes.dex files. By doing that, all pieces of an application package are put together back in one place, thus eliminating the worry of a modified APK conflicting with some separate odexed parts.
In summary, Deodexed ROMs (or APKs) have all their application packages put back together in one place, allowing for easy modification such as theming. Since no pieces of code are coming from any external location, custom ROMs or APKs are always deodexed to ensure integrity.
*Busybox-
A set of Unix tools / commands that has been compiled for use on your phone. These are not usually full-featured versions of the Unix commands found on the larger platforms counterparts, but they are pretty close and useful nonetheless.
*3G/4G-
3G/4G is the term generally used to describe 3rd/4rth Generation mobile telecommunications, specifically allowing for greater throughput of data over cellular networks.
*Baseband/Modem-
Baseband refers to the original frequency range of a transmission signal before it is converted, or modulated, to a different frequency range.
*Bloatware-
Software or 'apps' that you don't need, but come preinstalled to a device's /system partition, meaning that you cannot remove them unless the device has been rooted. Usually, these are apps are sponsored by a company and included by a carrier for profit. For example, the Photobucket app included on the G2 by TMobile.
*CDMA-
Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne and CDMA2000 (which are often referred to as simply CDMA), which use CDMA as an underlying channel access method.
*Firmware-
Programs stored in the ROM, EPROM, or flash memory that usually control various internal electronic devices (Hard Drives, Keyboards, Displays, etc). Firmware is typically 'fixed' software that is not updated in consumer devices, however it is often updated (or 'flashed') by advanced users to fix bugs or add features to the device. Flashing firmware designed for one device onto a different device, or not following a specific procedure while flashing will often render the device unusable.
*Flash-
Non-volatile computer storage that can be electrically erased and reprogrammed (similar to EPROM). No power is needed to maintain the information stored in the chip. This technology is primarily used in memory cards and USB flash drives for general storage and transfer of data between computers and other digital products. Because of its ease of use, speed, ability to be updated (see flashing), this technology is often used in mobile devices, PDAs, digital media players.
*Kernel-
The central or core software component of most operating systems. Its responsibilities include managing the system's resources (the communication between hardware and software components) and can provide the lowest-level abstraction layer for resources (especially memory, processors, and I/O devices).
*IMEI-
The International Mobile Equipment Identity is a number unique to every GSM, WCDMA, and iDEN mobile device, as well as some satellite devices. The IMEI number is used by the GSM network to identify valid devices and therefore can be used to stop a stolen device from accessing the network. For example, if a mobile device is stolen, the owner can call their network provider and instruct them to "ban" the device using its IMEI number. This renders the device useless, whether or not the device's SIM is changed. The IMEI can be displayed by dialing *#06#.
*IRC-
Internet Relay Chat. Basically a chatroom, or a cross between Instant Messaging and a forum.
*Open-source-
Open-source is software that anyone is allowed to see the 'source' code. In the context of Android, Open-source refers to the approach to the design, development, and distribution of software. This offers accessibility to a software's source code for modification, improvement, bug-fixing, and security-enhancement. CyanogenMod is based on this principle.
*ASOP-
Android Open Source Project
*Radio-
The cellular radio on the device which needs control software called firmware to control it.
*ROM-
Read Only Memory. In the context of an Android device, ROM is the internal flash memory where the core operating system resides. It can also refer to a specific version firmware that can be applied to a device through a process usually referred to as flashing. An improperly flashed ROM can often brick the device, rendering it unusable.
*SDK-
Software Development Kit. You can find the Android SDK at http://developer.android.com/sdk.
*Vanilla-
A clean, unmodified version of something. In the context of Android ROMs, vanilla refers to the stock ROM that came pre-installed on the device.
*Widget-
An application that lives (in other words, is always running) on the homescreen instead of being 'run' like a regular app. Common examples are calenders and weather widgets.
Android Specific Definitions
*ADB-
Android Development Bridge. Command line tool used to communicate with & control the device over a USB link from a computer. The ADB command is found in the Android SDK.
*Android-
Unveiled on 5 November 2007, Android is a mobile operating system running on the Linux kernel developed by Google.
*Apps2SD-
Move applications from the internal NAND memory on the device to a removable SD Card.
*CyanogenMod Updater-
An updater written by Cyanogen that allows you to receive OTA (Over-The-Air) updates to CyanogenMod.
*Dalvik-Cache-
The dalvik-cache directory holds all of the pre-compiled .dex files created from installed apps. These files are static and do not change unless the app is updated.
*Fastboot-
Fastboot is protocol used to directly update the flash filesystem in Android devices from a host over USB. It allows flashing of unsigned partition images. It is disabled almost all production devices since USB support is disabled in the bootloader.
*GApps-
See Google Apps.
*Google Apps-
An add-on for Google's applications (Market, GMail etc.), packaged separately to avoid copyright issues
*Logcat-
A debugging tool built into Android devices that displays system logs as they occur. See Logcat.
*NANDroid-
A set of tools that will enable anyone who has root on their Android device to make FULL system backups, in case something goes wrong or you want to try out that new experimental ROM/theme. NANDroid will backup (and restore) /system, /data, /cache, and /boot partitions.
*Recovery Mode-
A special environment that you can boot into for troubleshooting and upgrading purposes.
*Tethering-
Using a wireless device (e.g. an Android phone) to share it's wireless data connection to another device (e.g. laptop). With an Android device, the wireless data connection can usually be shared via WiFi, Bluetooth or USB connection.
*Wipe-
Usually refers to wiping data and cache partitions of the device.
*Zipalign-
Reduces the amount of RAM consumed when running the application by allowing data to be mmap'd in; which causes all uncompressed data within the .apk, such as images or raw files, to be aligned on 4-byte boundaries.
Hacking Definitions
*Aftermarket-
Aftermarket generally refers to any product or service applied or requisitioned by end-users to add usability or functionality to the original product. Many aftermarket modifications can void the manufacturer's warranty. From a manufacturer's perspective, the after-market is any goods or services offered by the manufacturer directly to end-users of a given product or service. After-market services include support for warranties, contracts, and parts and accessories sales.
*Brick-
a device that no longer functions, generally caused by a failed firmware or SPL update. Since the device no longer works as intended, it is often referred to as a "brick" or "paper-weight", since that is all it is good for.
*Flashing-
The process of applying a firmware image (or ROM) to a device. It generally entails a very specific order of steps. Failing to complete any one of these steps properly may result in bricking the device.
*Kang-
The process of creating a code based of someone else's code or reapplying code that someone else created into your own code (e.g. git cherry-pick)
*Rooting-
Obtaining root ("administrator", or "full") access to the device. This means you can mount its internal memory partition as read/write, which lets you do various things: have USB or Wi-Fi tethering, uninstall applications you otherwise can't uninstall (e.g. the Amazon MP3 store), install applications that need root access (such as AdFree), disable the camera shutter sound (simply by deleting the shutter sound file), overclock or underclock the CPU, install and boot Debian, and so on. Installing CyanogenMod roots the device in the process. The "Superuser" app controls what applications may gain root privileges.
*Unlock-
Most GSM devices are locked to only work with the sim cards of a particular carrier. Obtaining root access (e.g. installing CyanogenMod) on the device usually does nothing to the sim-lock. The usual way to unlock the device to all SIM cards is to obtain a subsidy unlock code from a carrier.

[INFO] "New User Guide Terms Android"

we decided to extend this guide in more threads, to give new users the chance to read more easily
Hi! I saw that many (myself initially) fail to understand the discussions of various topics of modding on this and other forums because of certain terms that are now characteristic of speech in any argument.
-Android operating system for mobile devices based on Linux kernel. Android is an open source project developed by the Open Handset Alliance (OHA). Google was the first company to work on Android and HTC has designed and implemented the first Android phone.
-AOSP: The term stands for AOSP Android Open Source Project, which is an initiative created to guide the development of the Android mobile platform.
-ADB (Android Debugging Bridge): application via command line (command prompt, DOS), is used to flash rom, make changes to the system, backup, install applications (using the command: adb push nomeapp.apk / system / app /), copy files from your device to PC (via the command: adb pull / path / inside / of / Android / filename nome_file_destinazione) and more. ADB is a tool included in the SDK of Android that allows you to manage your phone simply by connecting it via USB. For programmers, ADB is also used to execute commands on a virtual machine Android. detailed instructions.
- Apk (short for Android Package): is the file format used to install the Android software (it works similar, more or less, that is for Windows. Exe). Renaming the extension of this file. Zip you can open it with any operator of compressed files.
-App or Apps: abbreviation of the term application or applications
-App2sd (A2sd): procedure inherent in many Roma coocked, to move applications installed, or install later, the memory card instead of phone memory. to use it you must have an ext2 or ext3 or ext4 on the memory card. part of the application (the Dalvik cache) is still stored in the smartphone does not reduce the speed of execution. app2sd this is not to be confused with the various applications on the market, as those of the market allow the movement or storage of only applications that allow it.
-Bootloader (FASTBOOT): phone mode (while connected to USB mode with usb debug enabled) through which you can do many things, including obtaining root permissions, flash ROM, make backups, pushare files, remove files etc. ... the bootloader mode varies from terminal to terminal, refer to those sections for how to go into bootloader on your device.
-Brick (brickare, brickato): literally (translated in Italian) "BRICK". making the cell like a brick, a something of unusable if not as paperweights.
-Digital compass: The digital compass is able to detect the direction in which the device is pointing. This information can be used together with an appropriate mapping software to assist in navigation to unknown places.
-BusyBox: BusyBox is important because it lets you install it on your Android poteziare with many basic Linux commands. In fact, some powerful programs, such as Titanium backup and others, use busybox to carry out the instructions. In virtually a few kb there are so many beautiful little programs. guide: using titanium or backup.
-Cache: a temporary memory in which data are stored as may be eliminated without compromising the functionality of the system.
-Digital certificate: encrypted code issued to two or more parties by an authorized organization, and used to verify the identity of those parties by exchanging their public keys.
-Cupcake: Android 1.5 or relaise first official operating system pounces April 13, 2009
-Encryption: Procedure for the encoding of a systematic bit stream before transmission, aimed at avoiding that the contents can be decrypted by third parties.
Dalvik-Cache: cache used by the system to increase the execution speed of programs.
USB-Debug: mode of Android that is (turning the feature on your device via menu / settings / apps / Development / Debug USB) to allow the system to undergo special modifications.
Direct-Push Technology: Direct Push technology (push e-mail capabilities), developed by Microsoft, lets you receive new e-mail messages on their device, they are not received by your mailbox Inbox or Exchange Server. Items such as contacts, calendar and tasks are immediately updated on the device if they are changed or added on the Exchange Server.
-Emulator: it is found in the SDK and is a software that allows you to emulate (simulate) an android device. usually serves to developers (developers) to test applications.
-Digital Signature: A digital signature assures the recipient about the identity of the person who sent the file, and the absence of alterations made ​​after signing this.
-Firmware: Software comlpleto the phone, android rom often contains (the only operating system) the radio (software designed to handle all communications) and hboot (the part on the base, and boot management and partition of the phone) . The format depends on the parent company that issues them and shall be flashed through the tool or program.
-Flash (flash, flashed): install, installed.
-G. E. often written or GE (Google Experience): There are those phones that have the OS (see ROM for a definition) fully developed by Google without any addition or customization by the manufacturer that sells the device (for example the number of mobile Nexus is entirely GE). This designation often means that these phones are the first to receive updates of new versions of Android, because there being no additional software, as well as those developed by Google, the release is much quicker.
Another (more common) is that With Google.
Are those phones that despite having some customization software by the manufacturer, are fully compatible with the Google software and services with Android.
-GPRS: GPRS (General Packet Radio Systems - Radio systems for generic packages) is a data service for mobile devices. It is available for the devices that meet the GSM standard.
-GPS: GPS (Global Positioning System - Global Positioning System) is a radio navigation system based on satellites that allows the DENTIFICATION of a geographical position through a triangulation of points. The GPS is used on mobile devices for applications software for navigation.
-GSM: Short for Global System for Mobile communications (Global System for Mobile Communications), is the platform for mobile computing worldwide.
-HSDPA: HSDPA (High-Speed ​​Downlink Packet Access) is a technology for mobile devices that allows higher data speeds than traditional networks. Often referred to as 3.5G for faster downloading.
-HSPA: HSPA (High-Speed ​​Packet Access - High Speed ​​Packet Access) is a technology for mobile devices that improves the speed at which you can send and receive information on their mobile device. HSPA technology is used in 3G networks.
HSUPA: The HSUPA (High-Speed ​​Uplink Packet Access - access to packages for the high-speed) is a technology for mobile devices that provides (along with HSDPA) the possibility of having connections with fast download and upload very high by optimizing use of bandwidth.
-HVGA: The HVGA (Half-size Video Graphics Array) indicates a particular display resolution of 480 x 320 pixels.
-hboot: the part on the basis of partition and boot management and the phone
-Kernel: is the essential part of any operating system. Without going into technicalities, it manages hardware (drivers and other information about the hardware, for example). Android uses a modified Linux kernel and is entirely open source (ie source code is freely available and modifiable).
- Launcher: It 's the software that handles the desktop (icons, widgets, wallpapers etc..) Android operating system. In essence, is what appears when you access the phone after the unlock screen, called Lock Screen (see below) if it is enabled.
Android allows for excellent customization Lacuncher. Although all versions of Android will already have a default, it is possible (when this option is not blocked by the manufacturer) install as many as you want from those in the Market. Launcher The best known of those owners are not ADW Launcher, Launcher Pro, Helix Lancher.
Most producers customize more or less heavily, their phones (as long as they are not GE, see above), and modification of the launcher is usually the most common personalization. Motorola for example sviluppaMotoBlur (non-removable, and includes an additional set of changes including the Launcher), the HTC the Sense (removable; this also includes modifications to the deepest only launcher which also include the framework), Samsung TouchWiz the (removable) etc..
The change of Lacuncher makes it very often no longer available widgets developed for another Launcher.
-Leak Leaked or (escaped): this refers to the ROM or firmware that (strangely) escape to the Mother House, and is circulated on the net. are semi-official, in the sense that they are developed directly from 'manufacturer, but are not officially released (and therefore not fit to restore the guarantee of a device).
Screen-Lock or unlock screen: is the screen that appears after turning on and / or whenever you press the on / off the phone. Used to not press the keys when not using the phone. It requires a combination of specific touches, or gestures to be "removed"
-Nandroid (found in the recovery as amended): application that creates an image of the entire operating system, like norton gost and true image for windows.
-ODEX: type of compression that is used to free up memory and speed up your system. ODEX unzip the file compresses everything and creates a file. ODEX dall'apk deleting the file. dex then you end up with after launcher.apk and launcher.odex (so 'you have saved so much space and improved
the speed reading application). rom the ODEX can not be changed the subject.
-OTA: Over The Air - system that allows applications to receive updates directly from the network or system
Ext2/ext3/ext4-partition: partition on the memory card (which usually can be made using modified recovery) used to install applications on this media instead of filling up the phone memory. the ext is a type of file system used on Linux and is seen as part of the Android smartphone's internal memory. to partition the SD card in the sections and guides for your device.
-Profile A2DP: Advanced Audio Distribution profile (Advanced Audio Distribution) is a specification that refers to how two Bluetooth devices can transmit and receive streaming high quality audio. The A2DP allows the transfer of a unidirectional stream audio in stereo with two channels, such as music from one phone to a headset.
-Pull: used command in command prompt (eg adb pull / path / inside / of / Android / filename nome_file_destinazione) copy to your PC for a file or folder in the Android system.
-RUU: (Rom Updater Utility): A RUU is an executable for Windows, used by service centers, which basically formats all phone memory and you install an image of the official system. In general, the RUU ROM version containing a specific stock, the image of the baseband and radio, and bootloader, the versions are listed in the file name.
Radio-or banda or baseband (not the FM radio): software designed to manage all the communications device (phone, wifi, bluetooth, gps, etc. ...
-Recovery: a kind of mini operating system that is used to retrieve the cell from critical situations (brick, malfunction, etc. ....), do nandroid backup, perform the wipe, flash rom coocked and file format. Zip. The Recovery is properly called Recovery Mode and means the recovery mode in which you can perform actions such as, installing updates, format the phone, format and partition the SD and more. Updating the recovery.img (you can also do without the root) with a different and we have modified provisions advanced features without having to do other steps.
-RSS: RSS (Really Simple Syndication - Guild simple): indicates an Internet protocol used to distribute information that is updated frequently, such as a blog on the Internet, audio or video broadcasts or news headlines.
-Rom: the operating system. coocked roms are usually in. zip and go through recovery flashate
Coocked-Rom: cooked rom, created by chefs (who put together parts of rom applications, modifications, patches and so on) composed and enriched with new features
-ROOT (I take verbatim from androidpedia): What is root? In Unix-like operating systems is denoted by the root user with the highest privileges, ie, system administrator, also known as super user or superuser. (Cited in Wikipedia). Android being a linux system, then the user is root, which allows you to have total control of the phone. What a privilege we have to have root permissions? We have TOTAL control of the telephone. rootare the procedure for your device varies from terminal to terminal, consult the relevant sections to find out how to make your root device ..
G-sensor (gyro): The G sensor detects the position and movement of your device. It helps to orient the display to view both vertically or horizontally depending on how you hold the device. The G-sensor can be used in games to control the actions and other applications that require a movement to be able to be activated.
-SDK (software development kit): Software development kit, which we find in the tools folder that contains the file ADB. You can download it from for all platforms (Windows, Linux, Mac OS).
-S.O. (operating system): see ROM. In fact ROM and SO tend to coincide but while the first term is used to indicate the contents of any memory or the memory itself (it is in fact for Read Only Memory), the second indicates more specifically at a very specific piece of software and not any content that a memory can accommodate.
-Streaming: The term indicates the transmission of streaming audio or digital video using the Internet.
-Superboot: method to become the superuser (root-administrator) of your smartphone, with which you can make changes to the system, such as flash ROM, modify system folders etc. ...
-Tap (capped, plugged): equivalent of left-click on PC, then click in, clicked. TAP LONG = equivalent to right click on pc
-Thetering (wifi, bluetooth and usb): Mode is a connection between the phone is another device (mostly PC), through which you can take advantage of the internet's first, and basically use it as a modem, the second ( which as I said before can be a PC or another phone yet). May be predominantly via USB connectivity, bluetooth or wifi phone.
-Tablet is a tablet device that differs from a smartphone to the screen size (usually greater than the 5 "and for its strong propensity to navigation and document management. It usually does not incorporate a module for telephone calls (one exception is the Galaxy Tab), but often have a data connection via 3G or 4G as well as the WIFI.
Google has developed a special version of Android, called HoneyComb (3.X) for release in 2011. Nevertheless, there are Tablet with Froyo.
-VGA The VGA (Video Graphics Array) indicates a resolution of the display of 640 x 480 pixels.
-WCDMA: The WCDMA (Wideband Code Division Multiple Access) is a protocol for the transmission of data in a 3G cellular network.
-WVGA: The WVGA (Wide Video Graphics Array) indicates a display resolution of 480 x 800 pixels.
Wipe Dalvik-CACHE: reset the system cache. amended by recovery takes place.
Wipe-DATE (factory reset): hard reset (reset phone to factory settings, deletes all data and applications in your phone, no memory card). some recovery in the wiping the data format factory, not a complete hard reset, but a reset of all data in your phone, for a complete hard reset you should also wipe the system and boot from the recovery of the advanced settings or proceed with the procedure manual keystroke! how to do the hard reset via keyboard shortcut see the guides in their respective sections of your smartphone.
-ZIPALIGN: A form of compression that is used to speed up execution of applications. zipalign unzip the file and aligns the compressing apk file limit so 4byte 'Android takes up less ram to read and read more' quickly and then recreates the file. apk ^ ^

[INFO] "New User Guide Terms Android"

we decided to extend this guide in more threads, to give new users the chance to read more easily
Hi! I saw that many (myself initially) fail to understand the discussions of various topics of modding on this and other forums because of certain terms that are now characteristic of speech in any argument.
-Android operating system for mobile devices based on Linux kernel. Android is an open source project developed by the Open Handset Alliance (OHA). Google was the first company to work on Android and HTC has designed and implemented the first Android phone.
-ADB (Android Debugging Bridge): application via command line (command prompt, DOS), is used to flash rom, make changes to the system, backup, install applications (using the command: adb push nomeapp.apk / system / app /), copy files from your device to PC (via the command: adb pull / path / inside / of / Android / filename nome_file_destinazione) and more. ADB is a tool included in the SDK of Android that allows you to manage your phone simply by connecting it via USB. For programmers, ADB is also used to execute commands on a virtual machine Android. detailed instructions.
- Apk (short for Android Package): is the file format used to install the Android software (it works similar, more or less, that is for Windows. Exe). Renaming the extension of this file. Zip you can open it with any operator of compressed files.
-App or Apps: abbreviation of the term application or applications
-App2sd (A2sd): procedure inherent in many Roma coocked, to move applications installed, or install later, the memory card instead of phone memory. to use it you must have an ext2 or ext3 or ext4 on the memory card. part of the application (the Dalvik cache) is still stored in the smartphone does not reduce the speed of execution. app2sd this is not to be confused with the various applications on the market, as those of the market allow the movement or storage of only applications that allow it.
-Bootloader (FASTBOOT): phone mode through which you can do many things, including obtaining root permissions, flash ROM, make backups, pushare files, remove files etc. ... the bootloader mode varies from terminal to terminal, refer to those sections for how to go into bootloader on your device.
-Brick (brickare, brickato): literally (translated in Italian) "BRICK". making the cell like a brick, a something of unusable if not as paperweights.
-Digital compass: The digital compass is able to detect the direction in which the device is pointing. This information can be used together with an appropriate mapping software to assist in navigation to unknown places.
-BusyBox: BusyBox is important because it lets you install it on your Android poteziare with many basic Linux commands. In fact, some powerful programs, such as Titanium backup and others, use busybox to carry out the instructions. In virtually a few kb there are so many beautiful little programs. guide: using titanium or backup.
-Cache: a temporary memory in which data are stored as may be eliminated without compromising the functionality of the system.
-Digital certificate: encrypted code issued to two or more parties by an authorized organization, and used to verify the identity of those parties by exchanging their public keys.
-Cupcake: Android 1.5 or relaise first official operating system pounces April 13, 2009
-Encryption: Procedure for the encoding of a systematic bit stream before transmission, aimed at avoiding that the contents can be decrypted by third parties.
Dalvik-Cache: cache used by the system to increase the execution speed of programs.
USB-Debug: mode of Android that is (turning the feature on your device via menu / settings / apps / Development / Debug USB) to allow the system to undergo special modifications.
Direct-Push Technology: Direct Push technology (push e-mail capabilities), developed by Microsoft, lets you receive new e-mail messages on their device, they are not received by your mailbox Inbox or Exchange Server. Items such as contacts, calendar and tasks are immediately updated on the device if they are changed or added on the Exchange Server.
-Emulator: it is found in the SDK and is a software that allows you to emulate (simulate) an android device. usually serves to developers (developers) to test applications.
-Digital Signature: A digital signature assures the recipient about the identity of the person who sent the file, and the absence of alterations made ​​after signing this.
-Firmware: Software comlpleto the phone, android rom often contains (the only operating system) the radio (software designed to handle all communications) and hboot (the part on the base, and boot management and partition of the phone) . The format depends on the parent company that issues them and shall be flashed through the tool or program.
-Flash (flash, flashed): install, installed.
-G. E. often written or GE (Google Experience): There are those phones that have the OS (see ROM for a definition) fully developed by Google without any addition or customization by the manufacturer that sells the device (for example the number of mobile Nexus is entirely GE). This designation often means that these phones are the first to receive updates of new versions of Android, because there being no additional software, as well as those developed by Google, the release is much quicker.
Another (more common) is that With Google.
Are those phones that despite having some customization software by the manufacturer, are fully compatible with the Google software and services with Android.
-GPRS: GPRS (General Packet Radio Systems - Radio systems for generic packages) is a data service for mobile devices. It is available for the devices that meet the GSM standard.
-GPS: GPS (Global Positioning System - Global Positioning System) is a radio navigation system based on satellites that allows the DENTIFICATION of a geographical position through a triangulation of points. The GPS is used on mobile devices for applications software for navigation.
-GSM: Short for Global System for Mobile communications (Global System for Mobile Communications), is the platform for mobile computing worldwide.
-HSDPA: HSDPA (High-Speed ​​Downlink Packet Access) is a technology for mobile devices that allows higher data speeds than traditional networks. Often referred to as 3.5G for faster downloading.
-HSPA: HSPA (High-Speed ​​Packet Access - High Speed ​​Packet Access) is a technology for mobile devices that improves the speed at which you can send and receive information on their mobile device. HSPA technology is used in 3G networks.
HSUPA: The HSUPA (High-Speed ​​Uplink Packet Access - access to packages for the high-speed) is a technology for mobile devices that provides (along with HSDPA) the possibility of having connections with fast download and upload very high by optimizing use of bandwidth.
-HVGA: The HVGA (Half-size Video Graphics Array) indicates a particular display resolution of 480 x 320 pixels.
-hboot: the part on the basis of partition and boot management and the phone
-Kernel: is the essential part of any operating system. Without going into technicalities, it manages hardware (drivers and other information about the hardware, for example). Android uses a modified Linux kernel and is entirely open source (ie source code is freely available and modifiable).
- Launcher: It 's the software that handles the desktop (icons, widgets, wallpapers etc..) Android operating system. In essence, is what appears when you access the phone after the unlock screen, called Lock Screen (see below) if it is enabled.
Android allows for excellent customization Lacuncher. Although all versions of Android will already have a default, it is possible (when this option is not blocked by the manufacturer) install as many as you want from those in the Market. Launcher The best known of those owners are not ADW Launcher, Launcher Pro, Helix Lancher.
Most producers customize more or less heavily, their phones (as long as they are not GE, see above), and modification of the launcher is usually the most common personalization. Motorola for example sviluppaMotoBlur (non-removable, and includes an additional set of changes including the Launcher), the HTC the Sense (removable; this also includes modifications to the deepest only launcher which also include the framework), Samsung TouchWiz the (removable) etc..
The change of Lacuncher makes it very often no longer available widgets developed for another Launcher.
-Leak Leaked or (escaped): this refers to the ROM or firmware that (strangely) escape to the Mother House, and is circulated on the net. are semi-official, in the sense that they are developed directly from 'manufacturer, but are not officially released (and therefore not fit to restore the guarantee of a device).
Screen-Lock or unlock screen: is the screen that appears after turning on and / or whenever you press the on / off the phone. Used to not press the keys when not using the phone. It requires a combination of specific touches, or gestures to be "removed"
-Nandroid (found in the recovery as amended): application that creates an image of the entire operating system, like norton gost and true image for windows.
-ODEX: type of compression that is used to free up memory and speed up your system. ODEX unzip the file compresses everything and creates a file. ODEX dall'apk deleting the file. dex then you end up with after launcher.apk and launcher.odex (so 'you have saved so much space and improved
the speed reading application). rom the ODEX can not be changed the subject.
-OTA: Over The Air - system that allows applications to receive updates directly from the network or system
Ext2/ext3/ext4-partition: partition on the memory card (which usually can be made using modified recovery) used to install applications on this media instead of filling up the phone memory. the ext is a type of file system used on Linux and is seen as part of the Android smartphone's internal memory. to partition the SD card in the sections and guides for your device.
-Profile A2DP: Advanced Audio Distribution profile (Advanced Audio Distribution) is a specification that refers to how two Bluetooth devices can transmit and receive streaming high quality audio. The A2DP allows the transfer of a unidirectional stream audio in stereo with two channels, such as music from one phone to a headset.

Radio-or banda or baseband (not the FM radio): software designed to manage all the communications device (phone, wifi, bluetooth, gps, etc. ...
-Recovery: a kind of mini operating system that is used to retrieve the cell from critical situations (brick, malfunction, etc. ....), do nandroid backup, perform the wipe, flash rom coocked and file format. Zip. The Recovery is properly called Recovery Mode and means the recovery mode in which you can perform actions such as, installing updates, format the phone, format and partition the SD and more. Updating the recovery.img (you can also do without the root) with a different and we have modified provisions advanced features without having to do other steps.

Coocked-Rom: cooked rom, created by chefs (who put together parts of rom applications, modifications, patches and so on) composed and enriched with new features
-ROOT (I take verbatim from androidpedia): What is root? In Unix-like operating systems is denoted by the root user with the highest privileges, ie, system administrator, also known as super user or superuser. (Cited in Wikipedia). Android being a linux system, then the user is root, which allows you to have total control of the phone. What a privilege we have to have root permissions? We have TOTAL control of the telephone. rootare the procedure for your device varies from terminal to terminal, consult the relevant sections to find out how to make your root device ..
G-sensor (gyro): The G sensor detects the position and movement of your device. It helps to orient the display to view both vertically or horizontally depending on how you hold the device.

Yeah. I must say I agree. People just want to fly through the process without actually learning anything. I've been around for a while and I must say I even learned some new stuff (I never really understood what ODEX is)!

Nice guide, but could you please "prettify" it?

We need to be careful when making threads like this, to ensure the information is correct. I haven't gone through all of it, but there are at least a few inaccuracies. The most obvious is this one:

You do not need USB Debugging enabled for fastboot to work. USB Debugging is part of the ROM, and you are not booted into the ROM when you are booted in fastboot mode.
There are some inaccuracies in the adb one as well...

This.
And debug has to do with adb not fastboot.

Add AOSP to the list. Your you can add it in parentheses in the description of Android Operating System.

HSPA works on a UMTS network.
Baseband takes care of mobile network, not anything else; wifi/bt are a different chip (the same chip does wifi and bt).

What is?Boot loader,custom roms, CWM, modem, kernel??

Here is a post that helped me when I first decided to leave the Apple sheep heard...

What is Bootloader, custom ROM, Kernel, CWM, Firmware, Flashing, ADB, Root ?
Here I've gathered some info for newcomers to the Android world.
I've tried to keep it relatively simple. So if you want more info, follow the links!
What Is A Bootloader?
Taken from: Android 101: What is a bootloader? | Android-Does.com
In literal terms, 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.
As the bootloader kicks off before any piece of software on your device, it makes it extremely processor specific and every motherboard has it’s own bootloader. This is one reason that all Android phones have different custom ROMS developed due to high variance of processing hardware present on the device.
Android Bootloader
Every Android phone has a bootloader that instructs the operating system kernel to boot normally. But you need to understand one thing here that as Android OS is an open source OS and is available on a variety of different hardware, every manufacturer has their own version of bootloader specific for the hardware present in it’s environment. At its most basic level, your Android smartphone is like a hard drive, made of up several partitions. One of those partitions holds the Android system files, another holds all the app data you accumulate (which is how you’re usually able to update without losing all your stuff), and others to do more behind-the scenes stuff.
A lot has been said about bootloaders being “locked” and even the developer-friendly Nexus devices shipped with a locked bootloader (Nexus devices and a couple tablets are easily unlocked with a single command).In fact, a lot bootloaders are locked and encrypted, meaning simple commands like “fastboot oem unlock”, won’t do a thing.
Why are Bootloaders Locked?
A bootloader is usually locked on an Android device because although it’s an open source OS, still the manufacturers want you to stick to their Android OS version specifically designed for the device. In order to apply this concept, manufacturers lock the bootloader. With a locked bootloader on Android devices, it is virtually impossible to flash a Custom ROM and forced attempts void warranty as well as usually end up in bricks. Therefore, the first step is to always unlock the bootloader.
Why keep a bootloader out of reach? One of the biggest reasons is that the carriers and manufacturers don’t want to have to support hacked phones. The other is that a lot of time and money is spent developing these things. HTC Sense ain’t cheap. Neither is TouchWiz. But Samsung and HTC both have managed to find a middle ground with the modding community, and pressure is on other companies to do so as well.
Also a very good read about bootloaders: http://www.tested.com/news/feature/1879-know-your-android-bootloaderwhat-it-is-and-why-it-matters/
---------------------------------------------------------------------------
What is a kernel?
Taken from: Android A to Z: What is a kernel? | Android Central
A kernel isn't something unique to Android -- iOS and MacOS have one, Windows has one, BlackBerry's QNX has one, in fact all high level operating systems have one. The one we're interested in is Linux, as it's the one Android uses. Let's try to break down what it is and what it does.
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.
When software needs the hardware to do anything, it sends a request to the kernel. And when we say anything, we mean anything. From the brightness of the screen, to the volume level, to initiating a call through the radio, even what's drawn on the display is ultimately controlled by the kernel. For example -- when you tap the search button on your phone, you tell the software to open the search application. What happens is that you touched a certain point on the digitizer, which tells the software that you've touched the screen at those coordinates. The software knows that when that particular spot is touched, the search dialog is supposed to open. The kernel is what tells the digitizer to look (or listen, events are "listened" for) for touches, helps figure out where you touched, and tells the system you touched it. In turn, when the system receives a touch event at a specific point from the kernel (through the driver) it knows what to draw on your screen. Both the hardware and the software communicate both ways with the kernel, and that's how your phone knows when to do something. Input from one side is sent as output to the other, whether it's you playing Angry Birds, or connecting to your car's Bluetooth.
It sounds complicated, and it is. But it's also pretty standard computer logic -- there's an action of some sort generated for every event. Without the kernel to accept and send information, developers would have to write code for every single event for every single piece of hardware in your device. With the kernel, all they have to do is communicate with it through the Android system API's, and hardware developers only have to make the device hardware communicate with the kernel. The good thing is that you don't need to know exactly how or why the kernel does what it does, just understanding that it's the go-between from software to hardware gives you a pretty good grasp of what's happening under the glass. Sort of gives a whole new outlook towards those fellows who stay up all night to work on kernels for your phone, doesn't it?

What is CWM?
Taken from: AddictiveTips » Blog ArchiveWhat Is ClockworkMod Recovery And How To Use It On Android [Complete Guide]
ClockworkMod, abbreviated as CWM, is a popular custom recovery for Android phones and tablets developed by Koushik Dutta (Koush), a well-known name in the Android dev community. ClockworkMod recovery allows you to perform several advanced recovery, restoration, installation and maintenance operations on your Android device that aren’t possible with the stock recovery, and is one of the most common ways used to gain root access, back up device data, install a custom ROMs, kernels, themes, mods and more. However, for anyone new to Android customization and hacking, some of its options might prove to be a tad confusing. In what follows, we will cover all that this recovery is capable of doing, and how to do it.
About Android Recovery
All Android devices ship with a recovery console that is basically a partition on the device’s internal memory and can be booted into. The stock recovery of almost all Android devices provides a few basic yet handy options that allow you to factory reset your device and also to recover its operating system using an official ROM in zip format, but that’s all you can do with it. That’s where a custom recovery comes handy.
A custom Android recovery basically replaces the stock recovery with one that lets you do all you can do with the stock recovery, plus a plethora of more options to give you a lot more control on your device. With a custom recovery, you can install official and unofficial ROMs as well as other updates including apps, themes, kernels etc. using zip files, wipe not just user data but pretty much every partition on your device, mount the storage card for USB mass storage access without leaving recovery, partition your SD card, wipe Dalvik cache and battery stats, fix permissions, perform, manage and restore backups and so on.
Introduction To ClockworkMod
ClockworkMod recovery is one of the most widely used custom Android recoveries that is available for most mainstream Android devices. It is our custom recovery of choice here at AddictiveTips and almost every custom ROM that we install on our devices is done using this recovery.
ClockworkMod recovery has been developed by Koushik Dutta (also known as Koush) – the same guy who brought us the Android ROM Manager. He can be found at his blog hacking away at Android devices and at Twitter.

What's Firmware?
Taken from: What is Firmware, Rom and Firmware Flashing ? - I Teach Android
What the heck is this firmware? Definition of firmware is permanent software programmed into a read-only memory
In Simple words, you can understand it like windows for pc , in case of android we are going to do same thing – installing firmware (Froyo,Gingerbread, ICS, Jelly Bean etc.) on your phone. All phones have their different firmwares and installing tools regard less to the Andriod version (Froyo,Gingerbred). So never think that we can install any firmware on any android phone like we do in PCs.

What is Flashing?
Flashing refers to the overwriting of existing data on ROM modules present in an electronic device with new data. This can be done to upgrade a device or to change the provider of a service associated with the function of the device, such as changing from one mobile phone service provider to another or installing a new operating system.
In simple words flashing is called installing firmware on your phone.

What is Rooting?

When carriers and manufacturers sell you your device, it is almost certain that the device would come with certain software restrictions in place. There are a variety of different reasons why they might do that – some claim that this is done to protect the user, preserve the device’s warranty (this policy will vary from manufacturer to manufacturer), prevent users from getting rid of carrier bloatware apps or simply because the manufacturer would prefer if your device was distinguishable from the competition based purely on its user interface (i.e. Samsung’s TouchWiz, HTC Sense UI, etc).
Whatever their reasoning may be, chances are if you are looking to customize your device on a deeper level, you’d be out of luck and this is where rooting comes into play.
Rooting is essentially a process that allows users of smartphones, tablets or other devices running on Android to gain “superuser” access to the software. This will allow the user to perform administrative tasks such as writing to locations normally restricted by the system which in turn will allow for deeper customization. For iOS users, rooting on Android devices could be thought of as a close equivalent to jailbreaking your device.

What are custom ROMs?
Taken from: Custom ROMs For Android Explained - Here Is Why You Want Them
A stock ROM is the version of the phone's operating system that comes with your phone when you buy it.
A custom ROM is a fully standalone version of the OS, including the kernel (which makes everything run), apps, services, etc - everything you need to operate the device, except it's customized by someone in some way.
So what does the "customized" part mean? Since Android is open source, developers are free to take stock ROMs, modify them, strip them of garbage, optimize them, add things, and pretty much do whatever their imagination and skills allow.

What is ADB?
Taken from: Android 201: What is adb? | Android Central
According to Google "Android Debug Bridge (adb) is a versatile tool lets you manage the state of an emulator instance or Android-powered device." That certainly sounds like Google, doesn't it? To put it simply, adb is two different applications -- one running on your computer (Windows, Linux or Mac) and one running on your phone. When your phone is connected, and USB debugging is enabled, you can issue commands and communicate with the phone using your computer screen and keyboard.
Your Android phone uses a modified Linux kernel and tools as a base. This means that quite a few Linux commands can be sent via the adb server (the one running on your computer) to the adb client (the one running on your phone) and they will be executed. In our example picture, I've sent the "top" command over the wire to my phone, and my phone sent me back the information and printed it to my terminal.
This can be awfully handy for debugging things that aren't going right, as well sending those weird commands you need when you're hacking away in the middle of the night. Chances are, if you aren't actively debugging something or trying to break hack at your phone, you won't have much use for adb. And that's OK -- there's more than one way to have fun with an Android device.

What's baseband?
Baseband is the Radio or Modem version depending upon the Phone Model, Carrier and Android Software Stack version. The Radio/Modem file is flashed via Recovery tool (other options are ADB/ODIN). The mismatched Radio/Modem and ROM will lead to things not working. You need to find the matching Radio/Modem for the particular ROM you are running.
The radio firmware controls basic low-level functions like network connectivity, Wi-Fi, and GPS. Upgrading Radio firmware will fix connectivity issues, increase range or performance, decrease battery usage, etc. Incorrec tRadio frimeware can disable some functions in your phone such as MMS, 3G Data, VM Notifications, etc. Network operators/carriers select the correct version of the Radio firmware that is suitable for the phone, network and bandwidth.
There is also Modem and Baseband Radio Processor chipsets in Mobile phones. Usually, Google, Phone Manufacturers and carriers develop various types of modem firmware/software that controls the functions of these chipsets.
Firmware is the overall version of the Android system on your phone. Baseband version is the version of the radio embedded in the device. Since Android is based on the Linux operating system, they show you the current version of the Kernel used in the heart of the system. The Build number is just an indicator of which numerical version of the current overall system was built by developers for your device.
You cannot update any of these from the official web site. Updates to the Android system are pushed to the phone over-the-air by the manufacturer or the cell phone carrier. The only other way to update or change an Android phone it to install custom modified ROMs in place of the existing system firmware. That usually requires rooting the phone and a fairly considerable knowledge of how to hack hardware.
