Nexus 7 Root, Hacks, Mods And Development / Guide/tutorial: What can you do with "fastboot" and "adb" commands?« on: March 02, 2013, 02:14:18 PM »
This thread will be dedicated to learning about and teaching our members about fastboot and adb commands. It is a work in progress. If you have any specific questions, please don't hesitate to ask or PM. This is a guide specific to the Nexus 7 running fastboot commands from a Windows PC.
What is fastboot and how do I use it?
Fastboot is a tool used by the Android development platform, mainly for diagnostic and flashing partitions, over a USB interface. There is a driver seperate from your USB device drivers that allows the communication protocol. I will assume that the normal device drivers are installed before proceeding to fastboot commands. The fastboot tool is device specific. The tool is available in the Android SDK and must be compiled. Most toolkits for your device have the drivers already compiled for you and are contained in the root of the tool folder.
In order to use the fastboot tool, your device must be in the fastboot mode. The simplest way to get there is to hold both volume buttons while powering on.
I will assume that this lesson is redundant if you are using an Android SDK. For those who are not, you must execute the fastboot commands from a command prompt within the directory that the tool is located, unless the tool binary is in your PATH. It is easy to add the tool binaries to your PATH, but you must have a folder that is stationary containing the tools and binaries. on a windows computer, clicck START>right click My Computer>Properties>Advanced>Environment Variables>System Variables>double click Path. Add the full path to your tools folder.
If this seems too complicated, close all windows on your PC. Click Start>Run>cmd [hit enter].
This should bring up a command window. This will be where the fastboot commands are executed. There should be a command prompt with a file path. You need to place the fastboot file in this file path. Once the files are placed in this path, boot into fastboot mode, open a command window and type "fastboot devices" you should see this.
If this is not what you see, double check the path that you entered or make sure that the files are placed at your command prompt path.
If you see the serial number you have already begun sucessfully using fastboot commands.
What is "adb" and how do I use it?
Adb is what is known as Android Debugging Bridge. It is another communication protocol that functions inside the Android operating system. There are three portions of the protocol: client, server, and daemon. The client is run from the computer, the server is also on the computer, but only manages the communication, and the daemon runs on the device. This protocol can move files and perform functions with your data inside the OS. With Android version 4.2.2 there has been a security feature added requiring one to unlock the device and allow the connection upon the first connection to a new client.
Adb is used through a command prompt as well. USB debugging is required. Go to Settings>Developer Options>Android Debugging. Make sure this option is checked. If you extract the contents of the download folder and add it to your path, there should be no further setup. If you were not able to setup your path, follow the same procedure mentioned above by manually moving the files. You should be able to begin adb commands. Open a command window while connected to USB with debugging enabled (you should have a notification icon, windows may also install new drivers on first connection) type "adb devices." you should see the following.

There was an unofficial annoucement that has since been pulled, that declared March 13th @ 7am PDT as the registration date for Google I/O 2013. The conference dates are to be held from May 15-17 in San Francisco, Ca. I plan on going, that is if I can get a ticket. Reports claim that tickets sold out last year in as little as 50 seconds to 50 minutes. Either way, many that were willing to pay the hefty registration fees ($900 in 2012) weren't able to get tickets.
I had an idea a while back and just though I'd throw it out there...
Who would be willing to purchase an "official" number one Nexus forum shirt? We could have a logo contest and give a free shirt to the winner. I'm not talking about making money, just something to increase the pride in our community.

Some of you may have noticed that my Tapatalk mobile signature contains my current ROM that I run on my Razr Maxx. I didn't make up these names, but I use them anyway, including the upper-case alternations. Many of you also know that "project butter" was a big thing for Android version Jelly Bean. The ROMs that I use come from the developer R3D. He has been cooking ROMs for years, and I have been one of his software testers. His current project is "peanut butter & jelly bean." The ROMs have increase my benchmark scores by almost 30%! Yesterday he gave me ROM for that he ported from the Samsung Galaxy SIII to the Razr, which virtually turns the Razr into the GS3 running 4.1.2 with Touchwiz Nature UX!
Well, to get to the bottom of all this, R3D is currently cooking a ROM for the N7. I was so excited when I heard this, that I just had to spill the beans! I will keep everyone updated when I get more info.
A couple weeks ago, I was stuck at work sitting on my thumbs during the NFL playoffs. There were conditions not under our control that caused us to spend a lot of time just waiting around. My employees asked if I could watch the playoff games somehow on my Nexus.
These are my initial findings on this subject.
I found a website that hosts these streaming links. There are two types of applications for this: torrent streaming, and flash streaming. The flash streaming does not last very long. Every time I would get the stream running, the plugin or the browser would crash within minutes and wouldn’t restart even after clearing the cache. I tried with Dolphin and with Firefox to no avail. The torrent streaming requires additional software. Most of the software is not compatible for mobile platforms. I did find some beta software that actually worked… temporarily…
I was able to use my Razr Maxx to provide a hotspot. On 4GLTE, the speed is plenty sufficient. The site Wiziwig hosts many sports streams. From here you are able to que the desired stream. Some of the streams are fairly low quality and I wouldn’t dignify them by being viewed on my device. Some streams are HD quality.
I used Sopcast Beta v0.9 to stream the feed. Worked very well for a few minutes, then it would stop streaming. I had to reconnect to the source to continue the stream. This might have something to do with my mobile hotspot or the dynamic ip.
I plan on using my own HTPC in the future. I have a HVR-2250 in my PC capable of 1080i. I just found out that Hauppauge has their own software for the streaming too.
So I just found out that the mobile software for the tuner card I have is only available on devices with fruity flavors. A little tiffed at that one… I’ll have to come up with something else.
So I have my own solution set up and ready for tomorrow! I used my HVR-2250 and ran a digital cable signal to it. This tuner card has no problems decoding the local digital broadcasts. I did have to manually configure my tuner for the correct signal though. As it turns out, I had everything I needed already at my fingertips. The software needed was already installed as part of the package that came with the card. I used my gateway router to port forward the tuner hardware. Coupled with the software, I log into the web server and access all of my channels that are fed through my tuner card. I can access the web server with any device that supports flash. Now of course Android 4.2.1 doesn’t officially support Flash. The server uses an embedded player called Flowplayer that’s based on Flash and work’s great with Firefox! The web UI is awesome. I can even select my desired resolution up to 1080i and toggle fullscreen mode.
I'm trying to clean up this beast without formating my sdcard. There seems to be some remnants of the old file system left over from 4.1.2. Now I'm on CM10.1 and I'm not sure that the file setup is the same as a stock device. For instance, I have a /sdcard/Android/data folder containing 6.03Gb. I believe that this is my current location for installed app data. I also have /sdcard/0/Android/data containing 4.82Gb with files that haven't been modified since I switched to CM10.1. I think that this is the stock location for installed app data on 4.2.1. Can anyone verify this?
I also have /sdcard/0/0/Android/data containing 186.12Mb. I believe that this is the old directory from 4.1.2 that was carried over into the new file system.
My old CWM backups are located along this same path in sdcard/0/0/clockworkmod/ If I want to copy these backups over to the new directory, do I need the blobs folder too?

I have purchased a few games that require fairly large files to be downloaded. Quite a few of them exceed 1Gb. I seemed to have run out of storage on my 32Gb Nexus. I really dont want to admit defeat here and settle without installing the rest of my purchased games. So, I'm trying to clean up my sdcard storage manually. There is a folder /sdcard/obb that contains the downloaded files for the games. To my understanding, these are packed binary files that are extracted when the game is installed after download. Are these files still required? Unfortunately they are not even removed when the game is uninstalled, so they must be removed manually.
Over the holiday, I flashed CM10.1. I really seem to like it. This was an official release, so everything works. I haven't even had Bluetooth issues.
Anyone else jumped on this yet?

Does anyone have experience with the various mini-pc's out there that operate on Android? I thought this would be a nifty gadget to have around. With the possibility of the nexus 7 not utilizing miracast, another device that can sync all your media and plug directly into any TV sounds like an essential for my geek arsenal. Being smaller than a candy bar and just as powerful as any other android device are big selling points.
Thoughts? Advice? Reviews?

I am putting together a walkthrough on getting your Nexus 7 back to it's factory condition. This guide will include the how to get to the factory firmware image as well as the latest updates. I need to know which toolkits that our users are the most comfortable with or whichever ones you have used to unlock/root/install recovery. Please give me your input on this guide so that I can tailor it to your needs.
