[how to]lock/unlock your bootloader without htcdev(s-off required) - HTC Desire 510

READ THIIS!
*this thread is for desire 510. it will NOT work on m7,or any older device. please check the general forum for your particular device for a similar thread.
this thread will let you unlock your bootloader without htcdev,or let you change your hboot watermark from relocked or unlocked back to stock.
advantages
-no hassle with htcdev,tokens,or unlock codes
-no submitting your phones personal info to htc
-the ability to get back to 100% stock without any visual traces or records of having been s off or unlocking your bootloader.
*you must be s off.
*you must have superuser installed
read this:
this will not work if your s on. its not a way to magically unlock
the usual disclaimers:
use this info at your own risk. if it melts your phone into a little pile of plastic goo,its not my fault.
credits
-beaups for schooling me on echo comand protocol
-strace for originally discovering the location of the lock status flag(check out this thread for more info)
*i have tested this on my gsm cricket desire 510 variant(a11_ul). let me know if you try it on a different variant,or if youd like to dump partitions and have me take a look
IF you are an advanced user with adb/fastboot set up and some basic knowlede of the cmd window,you can skip to #2
1)set up adb(windows 7 and older)
-download this file
-install drivers: if you have htc sync installed,you should allready have drivers. if not,you can install htc sync,or install these modified htc drivers from revolutionary (driver mirror)
-unzip your miniadb_v1031.zip file. this is native funtionality in windows 7. you otherwise may need a utility such as "7-zip" to extract,or unzip it. place the unzipped folder onto the root of your C drive on your PC. root means the top level,not inside any folders. so just copy and paste,or drag and drop the folder onto C with everything else that is there. you may want to rename it to "miniadb_m7" since youll be putting some device specific files in here.
-open a command window. on windows 7,click the start bubble in the lower left and type "command" in the search box. xp i believe is similar or the same. doing this should open a small black command window.
-change to your miniadb_m7 directory. type the following at the prompt in your cmd window:
cd c:\miniadb_m7
your command promt should change to "c:miniadb_m7>" provided you: 1)unzipped the miniadb_v1031 zip file,and 2)put the folder on your c drive,and 3)entered the name of the folder correctly ("miniadb_m7" in this case)
-now make sure usb debugging is checked in developer options(you will need to turn it on first),and plug your phone into your PC with a usb cable
-make sure your phone is being recognized- type:
adb devices
if your drivers are installed correctly,this should return your phones serial number. you should hear the "found device" noises when you plug your phone in. if it starts installing drivers,wait for it to finish before typing the adb devices command.
if you get your serial number back,then enter this command:
adb reboot bootloader
this should take your phone to the "fastboot" screen,wich is white with colored letters. this is one mode of your bootloaders interactive modes. at the top youll see fastboot devices as confirmation youre in fastboot.
now enter:
fastboot devices
again,this should return your phones serial number. you should hear the "found device" noises when you plug your phone in. if it starts installing drivers,wait for it to finish before typing the adb devices command.
if you get your serial number back,you can enter the following to boot back to the phones OS:
fastboot reboot
and now,youve installed adb/fastboot and tested youre phones drivers. if at either spot,you have trouble and dont get your serial number back,there is some sort of connection issue. use these steps to troubleshoot:
troubleshooting connectivity issues:
-try a reboot of the PC
-try different usb cables and ports
-dont use a usb hub
-dont use usb 3.0
-make sure nothing capable of comunicating with the phone is enabled and running. htc sync,pdanet,easy tether,and even itunes have all been known to cause issues.
-windows 8 has been known to have issues. try a windows 7 or older machine
failing the above,
-i use these drivers for fastboot and adb(donwload and run as admin): http://downloads.unrevoked.com/HTCDriver3.0.0.007.exe (mirror)
failing that,try manually updating the drivers in the following manner:
-put the phone in fastboot mode(select fastboot from the hboot menu)
-open device manager on the PC
-plug in phone,watch for it to pop up in device manager.
-update drivers with device manager,pointing the wizard to the extracted
driver download folder from above
note that you can check the connectivity of the phone,and make sure drivers are working by in the following manner:
-open cmd window. change to directory containing adb/fastboot utilities
-adb with the phone in the booted OS,usb debug enabled,enter:
adb devices in a cmd window
-fastboot with phone in fastboot,enter:
fastboot devices in cmd window
in either case,a properly connected phone with working drivers installed should report back the phones serial number.

adb reboot bootloader
verify you are now locked
_____________________________________________________________________________________________
to UNLOCK your bootloader,enter the following:

When Typing just adb in cmd you will get whats called a "usage doc" which gives you a lits of commands that you can use:
Code:
-d - directs command to the only connected USB devic
e
returns an error if more than one USB device is
present.
-e - directs command to the only running emulator.
returns an error if more than one emulator is r
unning.

Good guide, pretty simple... Ill bookmark this, so I can send people that needs help here.
i have attached a zip that has the files i use to get basic use like for doing root to stock to upgrading 2.1-2.2 and other small things.
extract to C:\fastboot
in C:\fastboot you will find a "cmd" batch file. just run it and it should be ready for you to type in adb commands or fastboot. just make sure your in debug mode by doing all in the first post for installing drivers and all that.
U seriously bumped this thread? Lmfao

Trying to flash a rom on my phone (x10) and was making sure adb is working properly before i do anything. When flashing the new rom there's some bugs that require adb to fix. From my understanding "$" means i don't have su access. Thanks for the help btw. Sorry for bothering you. Just taking proper precautions.
EDIT
Sorry again. Found my answer. I forgot to unlock my device to accept superuser permissions. Thanks for your help
to check ur phone is detected by adb....
i type "adb shell" in cmd,and according 2 u i should show #.....but it shows $ to me......why?
To check connection, type "adb devices"
"adb shell" will allow you to work remotely on your device. If the $ doesn't change to #, then you don't have root access.

DISCLAIMER:
UNLOCKING THE PHONE WIPES DATA AND THE INTERNAL SD CARD. UNLOCKING THE PHONE WIPES DATA AND THE INTERNAL SD CARD. UNLOCKING THE PHONE WIPES DATA AND THE INTERNAL SD CARD. Therefore I HIGHLY suggest you do this before you start setting up the phone/installing apps so that you don't have to redo/reinstall much.
You can re-lock and unroot the phone, but I am still going to say that this voids the warranty.
I am not responsible for what you do to your device. This is for reference only.
Please follow each step carefully (ESPECIALLY make sure to read the part before step 14 VERY CAREFULLY.)
The CWM recovery may not be 100% functional yet, but you can install zips/roms and do backups for sure.
STEPS:
1 - Download this file and unzip it to C:\Nexus4
2 - Open a command prompt (On windows vista/7, go to Start menu and type cmd and press enter. On XP & below, go to Start > Run and type cmd and press enter.)
3 - In the command propmpt, run
Code:
cd C:\Nexus4 <press enter>
4 - On the phone, go to Settings > About phone. In the About phone menu, scroll down to "build number" and tap it until it says "You are now a Developer!"
5 - Go back to the main settings menu, and the Developer options tab should now be visible. Open that tab.
6 - In the Developer options menu, check USB debugging and Stay awake.
7 - Install the driver from here.
8 - Connect the device via USB.
9 - In the command prompt, run the command
Code:
adb devices <press enter>
and your serial number should pop up. If not, try unplugging the device, reinstalling the drivers, rebooting PC, and then retry.
10 - Now run the command
Code:
adb push SUBusybox.zip /sdcard/SUbusybox.zip <press enter>
It should say something like "XXXX KB/s (1191942 bytes in X.XXXs)"
11- If it said that, run the command
Code:
adb reboot-bootloader <press enter>
12 - The phone will show up in the bootloader. Now run the command
Code:
fastboot devices <press enter>
and your serial number should pop up.
13 - If your serial number popped up, run the command
Code:
fastboot oem unlock
and your phone will ask you if you want to unlock. Select yes with the volume buttons and press power.
13 - Your phone will go back to the bootloader screen, and at the bottom it will now say LOCK STATE - unlocked
****DO WHAT IS BETWEEN THESE RED DIVIDERS IF AND ONLY IF YOU WANT OTA UPDATES TO STILL WORK. IF YOU DON'T CARE, CONTINUE ON STEP 14 BELOW THE DIVIDERS.****
---------------------------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------------------------
Run
Code:
fastboot boot CWMrecovery.img <press enter>
and it should say something like
Code:
downloading 'boot.img'... OKAY [ X.XXXs]
booting... OKAY [ X.XXXs]
and your phone will boot into CWM recovery.
NOW SKIP TO STEP 17. ON STEP 18 IF IT ASKS YOU TO DISABLE RECOVERY OVERWRITE, TAP NO. STEP 19 SAYS YOU WILL HAVE CWM INSTALLED. YOU WON'T.
---------------------------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------------------------
14 - Now run the command
Code:
fastboot flash recovery CWMrecovery.img <press enter>
and it should say something like
Code:
sending 'recovery' (7754 KB)... OKAY [ X.XXXs]
writing 'recovery'... OKAY [ X.XXXs]
15 - If it said OKAY twice, then press the volume down key on the phone twice and it will say Recovery mode. Press the power key.
16 - Once in recovery mode, run the commands
Code:
adb shell mount system <press enter>
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.bak <press enter>
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak <press enter>
adb shell umount system <press enter>
the command prompt will say nothing back to you if there were no errors.
17 - On the phone, tap install zip from sdcard (NOT INSTALL ZIP FROM SIDELOAD), then tap choose zip from sdcard. Tap 0/. Now scroll down to SUBusybox.zip and tap it. Tap yes. It will then install.
18 - Now tap Go Back and then tap reboot system now. If it asks you to disable recovery overwrite tap yes.
19 - Once the phone boots back up it will be fully wiped and you will be rooted with CWM, SuperSU, and busybox installed
Thanks! So I'm assuming the latest CWM also runs a script that renames the auto reflash recovery? For my GN it was good enough to just rename the script in /system.

[REF] "Android for the Nexus 4" 101 & FAQs

The popularity of Nexus devices has increased significantly since the launch of the Nexus One in January 2010. Along with this popularity, forums such as xda-developers have also had an influx of new users, most of which are not developers, and are not well versed in the intricacies of Android.
After much thought (and some discussion on this thread), I’ve decided to create this thread as a compilation of FAQs, 101s, and “How-To’s” in the hopes that those coming to Android who want to learn will have another resource to help them learn. With that in mind, this thread is NOT meant to explain the quickest way to do things (you will NOT see toolkits or shortcuts discussed in this thread), nor is it meant to be a “fix-my-device” thread. It is created with for a purpose of learning, in order to expand users’ knowledge of Nexus devices and Android in general. See this post by kyphur for the general philosophy of this site, which I share.
I do not take myself to be an Android guru or developer. However, I do have a bit of knowledge to share. If you think things are missing or not accurate, I will be more than happy to add or revise anything. I will try to cover most of the basic topics related to Android, including drivers, ADB, fastboot, partitions, recoveries, bootloaders, root and reverting to stock. Again, I will not discuss toolkits, nor will I cover custom ROMs. Those have their own threads.
This will be an ongoing work-in-progress, as it takes considerable time to try and capture everything properly, and my time is limited. The order of the information will also change, as I haven't quite figured out the best way to present everything. (Currently there are some FAQs, including fastboot and ADB commands, followed by a list of reference and how-to threads.)
So, without further delay:
Frequently Asked Questions
What is Android?
Android is an open-source operating system for mobile devices. It is basically a java virtual machine running on a Linux-based kernel.
What is the Android SDK and do I need it?
SDK stands for "software development kit. Do you need it? If you are developing, then yes (but then you probably would be reading this thread now would you... ). If you are not developing, then no, you do NOT need to install it. It is just a waste of space. The only files you need (to interface with your PC) that comes from the SDK are the fastboot and adb files, and they can be found here for Windows, Linux, and MacOS.
Why do I need a driver for my Windows PC to recognize my device?
As with all hardware, Windows requires device drivers for it to be able to interface with the OS. Drivers are not required if you are using Linux or MacOS.
Where do I get the driver for my PC?
For the Nexus 4, the driver available in the SDK works. (You can get just the driver without the SDK from here.) However, I recommend using this package by 1wayjonny. It works perfectly and, unlike most other packages, 1wayjonny’s repack does not install any crapware along with it. That said, it doesn’t include an .exe file, so it needs to be installed manually from the .inf file. If you do not now how to do that, see here for instructions. Note: If you are using Windows 8, you will need to do this before you can install the driver.
Why do I need to install the driver twice?
Nexus devices use two main interfaces (there are actually a few more, but I will cover them later) to communicate with a PC. These are ADB (Android debug bridge) and fastboot, both of which will be covered later. The fastboot interface requires the N4 to be booted in fastboot (i.e., bootloader) mode. Thus, in order to install the fastboot driver, you need to boot your N4 into the bootloader. The ADB interface requires an Android kernel to be booted, i.e., your device needs to be booted normally, or in a custom recovery (covered later). Additionally, if your device is booted normally, you need to have USB Debugging set to enabled in settings (i.e., Settings->Developer options->USB debugging).
How do I boot my device into the bootloader (i.e., fastboot mode)?
Turn off your device, hold volume down, and press and hold the power button.
What is a command prompt?
A command prompt in Windows (or terminal in Linux/MacOS) is a command line window in which you can enter commands. To open a command prompt in Windows, you can hold the shift key and right click in the directory in which you want your command prompt open. Or, in a Windows Explorer window you can go to File-><name-of-window>->Open command window here.
What is a bootloader?
Without getting into too many technicalities, the bootloader is essentially the program that gets loaded first when starting your device, and it is responsible for booting the Android kernel. Think of the bootloader as the BIOS of a computer.
What does it mean if my bootloader is locked/unlocked?
Most (if not all) devices are shipped from the manufacturer with locked bootloaders. This is for security reasons. A locked bootloader does not allow easy flashing of images, which means that it is difficult to change or modify the operating system. Unlocking a bootloader (using fastboot) on most Nexus devices results in a complete loss of all personal data from the device. Having a locked or unlocked bootloader has no bearing on the functioning of the device. Unlocking it gives you more options to play around with the OS. Additionally, an unlocked bootloader means that you can easily root your device no matter what -- unlike most non-Nexus devices, if you lose root, it is trivial to get it back.
What is “root”?
Root essentially means that you have root (or superuser) access to the file system on Android. It is similar to being “administrator” on a Windows PC. It has nothing to do with your device or the bootloader, it has to do with the Android OS (i.e., you cannot “root” your device – you root the Andoid build that you are running). To have root, you need to be booted into the Android OS that you have rooted. If you are in fastboot mode, root is irrelevant.
How do I get “root”?
If you are booted into a custom recovery (recoveries will be covered later), root is enabled by default. If you want root while booted into Android, you will need to place two files on your system partition: an “su” binary which grants root access, and a superuser app that manages that access. The two that are available are ChainsDD’s Superuser and Chainfire’s SuperSU. Usually these files are packaged up in a zip file that is flashable using a custom recovery, but they can be flashed manually using ADB. Both of these methods will be described below.
If I unlock my bootloader, is that the same as root?
No, as was mentioned above, unlocking the bootloader allows you to (among a few other things) flash images easily to the device when not booted into the Android OS. Root allows you access to manipulate the files WITHIN the Android OS.
If I unlock my bootloader, does that mean that I have to root?
No.
If I unlock my bootloader, do I have to flash a custom ROM?
No.
Do I need to root to flash a ROM?
No.
What is a ROM?
A ROM is slang for an mobile OS build.
What are the different versions of Android, and is there a difference between say 4.2 and JOP40C?
Have a look at this link for an explanation of what (for example) JOP40C means, and what version of Android that is.
What is the difference between a stock ROM and a custom ROM?
A stock ROM is a ROM that is built by Google and is signed by Google’s platform keys. Everything else is a custom ROM.
What is this AOSP I keep hearing about?
AOSP stands for Android Open Source Project, and is a repository for the source code for Android. You can build your own ROM from AOSP. Details can be found on http://source.android.com/.
What is fastboot?
Fastboot can refer to three things: the actual interface between your PC and phone; the fastboot.exe file; or the “mode” of your device. For you to be able to use fastboot commands: your device has to be booted in fastboot mode, the fastboot driver for your PC needs to be installed, and the fastboot.exe file needs to be on your PC.
What are the fastboot commands?
The list of fastboot commands can be seen by typing “fastboot” (without the quotes) in a command prompt opened in the directory where you fastboot.exe file is located. See below.
Code:
fastboot
usage: fastboot [ <option> ] <command>
commands:
update <filename> reflash device from update.zip
flashall flash boot + recovery + system
flash <partition> [ <filename> ] write a file to a flash partition
erase <partition> erase a flash partition
format <partition> format a flash partition
getvar <variable> display a bootloader variable
boot <kernel> [ <ramdisk> ] download and boot kernel
flash:raw boot <kernel> [ <ramdisk> ] create bootimage and flash it
devices list all connected devices
continue continue with autoboot
reboot reboot device normally
reboot-bootloader reboot device into bootloader
help show this help message
options:
-w erase userdata and cache
-s <serial number> specify device serial number
-p <product> specify product name
-c <cmdline> override kernel commandline
-i <vendor id> specify a custom USB vendor id
-b <base_addr> specify a custom kernel base address
-n <page size> specify the nand page size. default: 2048
Along with these commands, there is an additional one: oem. For now, I will only cover the following commands: devices, flash, boot, erase, reboot, reboot-bootloader and oem.
These commands will work in fastboot mode, whether your bootloader is lock or unlocked:
oem: with a shipping bootloader (like what most of us have on our devices) there are two “oem” commands: “oem unlock” and “oem lock”. These commands are used to unlock and lock your bootloader, e.g., “fastboot oem unlock” will unlock your bootloader.
devices: this command checks to see if your device is properly connected to your PC in fastboot mode, e.g., “fastboot devices”
reboot: this command will reboot your device, e.g., “fastboot reboot”
reboot-bootloader: this command will reboot your device into fastboot mode, e.g., “fastboot reboot-bootloader”
These commands will only work in fastboot mode IFF your bootloader is unlocked:
flash: this command is used to flash images to partitions (partitions will be covered later) on your device. It cannot be used to “flash” individual files or .zips. For example, to flash the system partition, the command would be “fastboot flash system system.img”
boot: this command boots a kernel without flashing it to your device. For example, to boot an insecure kernel called “test.img”, the command would be “fastboot boot test.img”
erase: this command erases a specified partition. For example, to erase the cache partition, the command would be “fastboot erase cache”
The above mentioned commands are the basics for flashing your device. You should get familiar with them.
What is ADB?
ADB can refer to two things: the actual interface between your PC and phone, or the adb files (the .exe and two .dll files for Windows). For you to be able to use adb commands: the adb driver needs to be installed on your PC, the adb files need to be on your PC, and your device has to be booted either in recovery mode or booted normally into Android. Additionally, USB debugging needs to be enabled if booted into Android.
What are the ADB commands?
The list of ADB commands can be seen by typing “adb” (without the quotes) in a command prompt opened in the directory where your adb.exe file is located. See below.
Code:
Android Debug Bridge version 1.0.29
-d - directs command to the only connected USB device
returns an error if more than one USB device is present.
-e - directs command to the only running emulator.
returns an error if more than one emulator is running.
-s <serial number> - directs command to the USB device or emulator with
the given serial number. Overrides ANDROID_SERIAL
environment variable.
-p <product name or path> - simple product name like 'sooner', or
a relative/absolute path to a product
out directory like 'out/target/product/sooner'.
If -p is not specified, the ANDROID_PRODUCT_OUT
environment variable is used, which must
be an absolute path.
devices - list all connected devices
connect <host>[:<port>] - connect to a device via TCP/IP
Port 5555 is used by default if no port number is specified.
disconnect [<host>[:<port>]] - disconnect from a TCP/IP device.
Port 5555 is used by default if no port number is specified.
Using this command with no additional arguments
will disconnect from all connected TCP/IP devices.
device commands:
adb push <local> <remote> - copy file/dir to device
adb pull <remote> [<local>] - copy file/dir from device
adb sync [ <directory> ] - copy host->device only if changed
(-l means list but don't copy)
(see 'adb help all')
adb shell - run remote shell interactively
adb shell <command> - run remote shell command
adb emu <command> - run emulator console command
adb logcat [ <filter-spec> ] - View device log
adb forward <local> <remote> - forward socket connections
forward specs are one of:
tcp:<port>
localabstract:<unix domain socket name>
localreserved:<unix domain socket name>
localfilesystem:<unix domain socket name>
dev:<character device name>
jdwp:<process pid> (remote only)
adb jdwp - list PIDs of processes hosting a JDWP transport
adb install [-l] [-r] [-s] <file> - push this package file to the device and install it
('-l' means forward-lock the app)
('-r' means reinstall the app, keeping its data)
('-s' means install on SD card instead of internal storage)
adb uninstall [-k] <package> - remove this app package from the device
('-k' means keep the data and cache directories)
adb bugreport - return all information from the device
that should be included in a bug report.
adb backup [-f <file>] [-apk|-noapk] [-shared|-noshared] [-all] [-system|-nosystem] [<packages...>]
- write an archive of the device's data to <file>.
If no -f option is supplied then the data is written
to "backup.ab" in the current directory.
(-apk|-noapk enable/disable backup of the .apks themselves
in the archive; the default is noapk.)
(-shared|-noshared enable/disable backup of the device's
shared storage / SD card contents; the default is noshared.)
(-all means to back up all installed applications)
(-system|-nosystem toggles whether -all automatically includes
system applications; the default is to include system apps)
(<packages...> is the list of applications to be backed up. If
the -all or -shared flags are passed, then the package
list is optional. Applications explicitly given on the
command line will be included even if -nosystem would
ordinarily cause them to be omitted.)
adb restore <file> - restore device contents from the <file> backup archive
adb help - show this help message
adb version - show version num
scripting:
adb wait-for-device - block until device is online
adb start-server - ensure that there is a server running
adb kill-server - kill the server if it is running
adb get-state - prints: offline | bootloader | device
adb get-serialno - prints: <serial-number>
adb status-window - continuously print device status for a specified device
adb remount - remounts the /system partition on the device read-write
adb reboot [bootloader|recovery] - reboots the device, optionally into the bootloader or recovery program
adb reboot-bootloader - reboots the device into the bootloader
adb root - restarts the adbd daemon with root permissions
adb usb - restarts the adbd daemon listening on USB
adb tcpip <port> - restarts the adbd daemon listening on TCP on the specified port
networking:
adb ppp <tty> [parameters] - Run PPP over USB.
Note: you should not automatically start a PPP connection.
<tty> refers to the tty for PPP stream. Eg. dev:/dev/omap_csmi_tty1
[parameters] - Eg. defaultroute debug dump local notty usepeerdns
adb sync notes: adb sync [ <directory> ]
<localdir> can be interpreted in several ways:
- If <directory> is not specified, both /system and /data partitions will be updated.
- If it is "system" or "data", only the corresponding partition
is updated.
copkay has written up a great guide on the use of the “backup” and “restore” commands in this thread, so I will not cover those commands here.
For now, I will only cover the following commands: devices, reboot, reboot bootloader, push, pull and shell.
devices: this command checks to see if your device is properly connected to your PC in ADB mode, e.g., “adb devices”
reboot: this command will reboot your device, e.g., “adb reboot”
reboot-bootloader: this command will reboot your device into fastboot mode, e.g., “adb reboot bootloader”
push: this command copies a file (or directory) to your device from your PC. For example, say you wanted to copy to your /sdcard folder on your device a file called junk.jpg, which is stored on your PC in c:\. The command would be “adb push c:\junk.jpg /sdcard/” (assuming the folder is mounted – to be covered later). Petrovski80 has added more details on copying files to your device in his thread here.
pull: this command copies a file (or directory) to your PC from your device. For example, say you wanted to copy to your c:\ directory on your PC a file called junk.jpg, which is stored in the /sdcard folder on your device. The command would be “adb pull /sdcard/junk.jpg c:\” (assuming the folder is mounted – to be covered later).
shell: this command opens a “shell” to your device so you can issue commands directly to the Android OS. The command is “adb shell”. Your prompt will change to “$” which means that you are now issuing commands to Android, not to your PC. (At some point, I will try to put together a list of commonly used commands, but for anyone that has used Linux, they are essentially the same.)
What are the partitions on a the N4?
A Nexus 4 has the following partitions:
modem -> /dev/block/mmcblk0p1
sbl1 -> /dev/block/mmcblk0p2
sbl2 -> /dev/block/mmcblk0p3
sbl3 -> /dev/block/mmcblk0p4
tz -> /dev/block/mmcblk0p5
boot -> /dev/block/mmcblk0p6
recovery -> /dev/block/mmcblk0p7
m9kefs1 -> /dev/block/mmcblk0p8
m9kefs2 -> /dev/block/mmcblk0p9
m9kefs3 -> /dev/block/mmcblk0p10
rpm -> /dev/block/mmcblk0p11
aboot -> /dev/block/mmcblk0p12
sbl2b -> /dev/block/mmcblk0p13
sbl3b -> /dev/block/mmcblk0p14
abootb -> /dev/block/mmcblk0p15
rpmb -> /dev/block/mmcblk0p16
tzb -> /dev/block/mmcblk0p17
metadata -> /dev/block/mmcblk0p18
misc -> /dev/block/mmcblk0p19
persist -> /dev/block/mmcblk0p20
system -> /dev/block/mmcblk0p21
cache -> /dev/block/mmcblk0p22
userdata -> /dev/block/mmcblk0p23
DDR -> /dev/block/mmcblk0p24
grow -> /dev/block/mmcblk0p25

What does mounting mean?
In order for a device to have access to files, the partition on which those files reside needs to be “mounted”. If you are in recovery, you can easily do this by going to the mounts menu and mounting the appropriate partition. If you are booted in Android, you will need to mount the partition yourself. The /sdcard folder is already mounted by default, however.
How do I mount the system partition?
In recovery: go to the mount menu and mount /system
In Android, on your device: you need root, and a file explorer with root access
In Android, connected via ADB (root required): you need to type the following command in a command prompt:
adb shell
su
mount -o remount,rw -t ext4 /dev/block/mmcblk0p21 /system
To explain this a bit:
-o remount,rw <== this remounts a partition that is already mounted (as read-only), as read-write
-t ext4 <== this specifies to mount it as ext4
/dev/block/mmcblk0p21 <== this is the system partition
/system <== this is what you are mounting it as
What is recovery?
Recovery is like a mini OS, which allows you to perform various functions, usually related to flashing files to your device, or updating files, or backing things up, etc. The stock image has a recovery included, but its functionality is very limited. There are a number of custom recoveries available, but the two most popular for the Nexus 4 are CWM and TWRP. There are various versions of each. More details to come in this section.
I see an Android lying on its back when I boot into recovery. Why?
What you see is the main screen of the Nexus stock recovery. To access the menu, you need to push and hold power and press volume up.
I just flashed CWM, but every time I try to boot into CWM, I keep seeing the stock recovery. Why?
If you updated your Android build using an OTA update file (either manually or over-the-air), the update placed two files on your device that re-flash the stock recovery every time you reboot your device. These two files are:
/system/etc/install-recovery.sh <== this is the script that installs the patch file
/system/recovery-from-boot.p <== this is the patch
You have to rename (or delete) one or both of them, then re-flash your custom recovery. Now it will stick.
What is an insecure boot image?
An insecure boot image is one that has root enabled for the shell user (i.e, ADB) by default on boot. This means that if you have booted or flashed an insecure image, when you connect your device to a computer, and open a shell via ADB, you will be userid 0 (or root) without having to "request" root access via the su binary. This makes somethings easier -- for example, you can now use the "remount" command in ADB to mount /system without having to type the full mount command in a shell. (More to add later.)
How do I root?
As was mentioned earlier, you need to place the su binary and the superuser app into the right spots on your device. In order to do this, you need to already have root access. There are two ways: flash a root package in recovery (instructions here), or manually place the files in the appropriate spots (I will add instructions on how to do this at a later time).

Just to let you know, there's a mistake on " How to boot into the bootloader". It says to hold down vol+&vol- and press power, bit you only have to hold vol- and power.
Sent from my Nexus 4 using Tapatalk²
I think accessing bootloader mode is only by pressing volume down and the power key. I tried vol up + vol down + power key (the way you do it for the Galaxy Nexus) and it was a no go.
Maybe I'm just dumb, but on stock recovery, i get to the android with the triangle and hold vol up + power and my phone just turns off. What the heck am I doing wrong?

Glad to see you again old buddy--
You were of tremendous help guiding me in my early N1 days and pushing me into learning the correct ways to do things sdk/adb/fastboot etc, not the shortcuts some were taking
I am sure many others have been helped also--
Don't think you were a Mod back then, so congrats on that also--
I am currently active in the One S Forum. But, follow the N4 and GN2 as one of them will be my next phone in the near future--

Amazing... There should be a thread like this on every Nexus device, or at least the most popular Nexi this days, it would be really helpful

You are right, it is for Windows, Linux and MacOS. I have a habit of using "PC" to mean "computer". I will adjust the wording in the first post.
this is very useful. thanks!
I have a question that wasn't answered in this FAQ. I was hoping someone could shed some light on the issue, then the OP could update the post to help others...
Basically, on my last Android phone my nandroid backups were all located on my SD card, under clockworkmod/backups. Now, they are located under mnt/shell/emulated.
I am new to emulated partitions and don't really get what is going on. I seem to be able to access various contents of my SD from the following directories:
mnt
sdcard
storage - which also has emulated and sdcard0 subfolders
The contents of these locations is not identical though! Could someone please explain what is actually going on?
Many thanks

This is new in Jelly Bean. Not sure why Google changed it. That said, they are all symlinks for compatibility with various apps. You data is actually stored in /data/media/0. This is your "sdcard" and the other locations should be pointing to that, so the contents of the "other locations" should be identical to that.

Thanks for the answer. I will try and express my current understanding in a few statements. If any of it is wrong I would appreciate someone putting me correct.
The N4 has one large 16Gb drive.
On this drive is the data/media folder, which is preserved when full wiping, flashing roms, etc.
The /data/media/0 folder is meant to represent the SD card. Without root access this is all file explorers will see.
Instead of saving to data/media/0/clockworkmod/backup, CWM now backs up to data/media/clockworkmod/backup. This is why you need a root file explorer to see the backups.
The 'SD card', 'mnt' and 'storage' folders are all symlinks to /data/media.
Assuming all that is correct how, how would an unrooted user delete folders from data/media, other than data/media/0.
Also, will it be possible for CWM to change their backup directory to what it has always been?

I came across this comment in another thread that answered one of my questions:
"I believe the location was changed because of the multiple users feature that has been incorporated into android.
If you go into storage you'll notice a folder called sdcard0. This is how android handles multiple users the next user would have a folder called sdcard1 and the next sdcard2 so forth and so on.
CWM had problems handling this so Koush changed the location to get around the problem."

The other thing that wasn't quite correct is that data/media is NOT preserved when doing a wipe if you are using the stock recovery, but is preserved if you are using a custom recovery like cwm or twrp.

Install ADB on Windows & ubuntu 12.04 or 12.10

If you need to flash ROM even using fastboot for Smartphone or Tablet in which they use Android OS! Then Ubuntu OS is needed!
This is a guide I made for ubuntu users and included a guide for windows users to setup Android SDK which contains ADB.
Android Debug Bridge (ADB) provides a terminal interface on your PC to interact with your device's file system. This can be useful for many things like installing & uninstalling apps, logcat, backup & restore, and hacking your device just to name a few.
ubuntu 12.04 & 12.10 Guide
1. Go here and download android-sdk (not the adt-bundle)....
https://hotfile.com/dl/241406263/5e6a306/android-sdk_r22.0.5-linux.tgz.html
2. Place the downloaded file in your home folder and then extract it and you should get a folder named android-sdk-linux (do not rename it).
3. If you’re on a 64bit machine run these commands in terminal to make sdk compatible with 64bit (if you’re on 32bit machine then skip this step)....
sudo apt-get update
sudo apt-get install ia32-libs-multiarch
4. Run this command in terminal to install jdk if you don’t have it already....
sudo apt-get install openjdk-6-jdk
5. Navigate to the home folder where you extracted android-sdk-linux and open the folder then open the folder named tools
6. Inside the tools folder there will be a file named android... double click it and select run then android sdk manager will open.
7. In the center pane deselect everything... Now only select the following....
Android SDK Tools
Android SDK Platform-tools
Android Support Library
8. Once selections have been made click on install packages and wait till finished.
9. Upon completion of step 8 in terminal run this command....
sudo gedit ~/.bashrc
When the file opens, go to the very bottom and copy/paste the following 3 lines (make sure they’re each on separate lines)....
# Android tools
export PATH=${PATH}:~/android-sdk-linux/tools
export PATH=${PATH}:~/android-sdk-linux/platform-tools
10. Now reboot your computer.
11. Set your phone to usb debugging then plug it to your pc after pc is done booting
12. Open a terminal on your pc and enter....
adb devices
If all went well, you should see your phone’s serial number and you’ll be ready to go.

You can use steps 5 & 6 to open Android SDK Manager & update your ADB/SDK installation. Only select your installed packages then update.
Also if you only need the fastboot/adbtools:
sudo add-apt-repository -y ppa: phablet-team/tools
Note: delete the space after"-y ppa:" -xda creates smileys like ppa
sudo apt-get update
sudo apt-get install -y phablet-tools

Thanks man! It's also good way!
Followed this guide (thank you for posting) but couldn't connect. Scratched around and found I needed to create a new file in /etc/udev/rules.d with:
Code:
SUBSYSTEM=="usb", ATTR{idVendor}=="<4-char_verndorID>", ATTR{idProduct}=="4-char_productID", MODE="0666", OWNER="username"
Followed by:
Code:
sudo restart udev
Then plugged device in and it worked!

What did you name the new file you created? Or did you add this string to another existing file from the rules.d directory? I'm not sure what I've done wrong, but I get
Code:
[email protected]:~$ adb devices
No command 'adb' found, did you mean:
Command 'cdb' from package 'tinycdb' (main)
Command 'gdb' from package 'gdb' (main)
Command 'dab' from package 'bsdgames' (universe)
Command 'zdb' from package 'zfs-fuse' (universe)
Command 'kdb' from package 'elektra-bin' (universe)
Command 'tdb' from package 'tads2-dev' (multiverse)
Command 'pdb' from package 'python' (main)
Command 'jdb' from package 'openjdk-6-jdk' (main)
Command 'jdb' from package 'openjdk-7-jdk' (universe)
Command 'ab' from package 'apache2-utils' (main)
Command 'ad' from package 'netatalk' (universe)
adb: command not found

This is after following each step, adding the three lines to the end of .bashrc and rebooting.

@atmu5fear, inferring that you're new to Linux (a common background for all), some notes:
Unlike wlth Win-d'oh-s, there is a worldwide development community that's always working toward improvement of every aspect of the system, including echoed messages and documentation. You may have to shake off the tendency to ignore Windudz messages, which are frequently unhelpful. Linux command echoes are much more on-target. Also, look for files such as README in rules.d and read it!
Now before creating a new config file (which may not be necessary on your system), see the top feedback line: "No command 'adb' found." First, see that the adb binary is present and that it has exec permission. (Since it's a small file and functions alone, I prefer to copy it to the folder I'm working from.)
If it then runs but won't connect, read on...
Directory (or "folder") names with a trailing '.d' are special: They configure, control, or provide executables for daemons (programs which run continuously, providing a service).
Within service-config.d folders, if the service steps through the files sequentially (as in this case), then it does so based on each filename. (True except for the special case of rc.d, iIRC, in which order is set by the special program rcorder).
So in this case, for example, since the existing files are named 70-whatever, your newly-created file could be 80-atmu5fears-phone to load after the others.
Should connect.

Thanks @qtoon for the reply. I'm not really new to Ubuntu, albeit, it's been a while. First started using it just prior to the realease of Hardy Heron 8.04 LTS. That being said I am certainly no expert, but am somewhat familiar and comfortable with the command line. I did read the README file before posting, but since I'm not all that familiar with configuration files and the like, I figured maybe I should ask.
As per your suggestion i moved the ADB binary to my home folder, not necessarily my working folder, but to test to see if the adb command would be recognized in terminal.
Code:
mv ~/ADB/android-sdk-linux/platform-tools/adb ~/
Still got same result so I moved it back, then went on to make a new file and add the suggested string
Code:
sudo > /etc/udev/rules.d/80-atmu5fear-adb
sudo gedit /etc/udev/rules.d/80-atmu5fear-adb
After saving and restarting udev I still get the same "adb command not found" error.
I then changed the string to read OWNER"atmu5fear" instead of "username", still nothing
Any more suggestions?
Thanks
atmu5fear
Sorted it out
instead of:
adb devices
i needed to input:
./adb devices
It's listed, and in order to use the adb shell:
./adb shell
once in the shell all adb commands work
I get this error...
[email protected]:~$ sudo > /etc/udev/rules.d/80-sjy-phone
bash: /etc/udev/rules.d/80-sjy-phone: Permission denied
ok....... didn't need to add a file, changed phone usb mode to media device and all is ok.
thanks

Didn't think to mention that, apologies.
Quick 'why' on the ./ here.
Glad you got it running.
Just tried on 14.4 and worked like a charm.
Note: No need to reboot the computer, just reload the bash config with
Code:
source ~/.bashrc
Thanks
A good step by step guide
i will try it and see if it works
Thanks again
Hello, can someone help me ? - I m having problems connecting my device with adb (I ve connected several other devices before with no problems).
I ve got an Allwinner A20 tv box, it worked fine for a few months then one day, after being on (but idle) for a few hours, I noticed the screen was blank but the light on the front was blue (indicating it was on, red is standby). It would not respond to the remote control or to anything, so I unplugged it and since then it will not boot and the screen is blank, the red light will light up but that is it. I ve eliminated the remote controller not working, but I cant boot the device.
So I ve tried connecting via ADB (with Ubuntu) but I cant get the device to show up after typing "adb devices".
Using this guide:
http://androidonlinux.wordpress.com/2013/05/12/setting-up-adb-on-linux/
I can get the vendor id and device id and I ve added it and the manufacturer to udev/modeswitch devices, but when I type "sudo usb_modeswitch -v 0x1f3a -p 0xefe8 -S -R -W"
I get the following error:
~/Android/sdk/platform-tools$ sudo usb_modeswitch -v 0x1f3a -p 0xefe8 -S -R -W
Take all parameters from the command line
* usb_modeswitch: handle USB devices with multiple modes
* Version 2.1.1 (C) Josua Dietze 2014
* Based on libusb1/libusbx
! PLEASE REPORT NEW CONFIGURATIONS !
DefaultVendor= 0x1f3a
DefaultProduct= 0xefe8
SierraMode=1
NeedResponse=0
Look for default devices ...
found USB ID 048d:1336
found USB ID 1d6b:0002
found USB ID 19a8:2036
found USB ID 1f3a:efe8
vendor ID matched
product ID matched
found USB ID 1d6b:0001
found USB ID 062a:0102
found USB ID 1d6b:0001
Found devices in default mode (1)
Access device 004 on bus 003
Current configuration number is 1
Use interface number 0
USB description data (for identification)
-------------------------
Manufacturer: not provided
Product: not provided
Serial No.: not provided
-------------------------
Send Sierra control message
Error: Sierra control message failed (error -7). Abort
I ve searched Google for the error code but I cannot find anything.
The device was rooted and USB debugging was on.
Any help would really be appreciated.
Thanks
