The stock ROM is the preinstalled operating system on your device. The stock ROM has limited functionalities that are defined by the phone’s manufacturer.
If you wish to have extra features added to your device, then you will have to resort to custom ROM. As you all know Android is an open source platform where a developer can take all the source code from Google and build their own operating system images for Android phones and tablets from scratch.
This Custom ROM is been updated regularly by the community and developers where they fix all the bugs related reports. To Install Any Custom ROM for Nexus7 2012, you need Tarp Recovery on your device.
You can read the description and the features that come with the custom ROM given below for Nexus7 2012 devices. Lineage OS is the legacy of the old famous custom firmware known as Cyanogen or CM.
The company behind Cyanogen. Inc has withdrawn the popular Android mod, Cyanogen that left many of its users disappointed. Few believed that the legacy of Cyanogen will be taken forward by a new Android mod, however, it was all uncertain.
It is amidst such chaos that Lineage OS was introduced and definitely it gave back everyone the answer concerning Android mod. Lineage OS is one of the best custom ROM for any Android smartphone.
The developer of Asp Extended has promised to add many new features and make it even better for future updates. Just like every other custom ROM, Asp Extended ROM also has many features which as a Status bar and Lock screen customization, Theming, DU’s naval/Fling bar, ASPA Pie, and many other features.
CrDroid is designed to increase performance and reliability over stock Android for your device also attempting to bringing many of the best features existent today. Resurrection Remix is a combination of the stability provided by CM and features from Slim, OFNI and original Remix builds providing an awesome combination of performance, customization, power and the newest features brought directly to your device.
Unfortunately, since AKP either stopped development or will make a comeback later this year, they changed their Source to Lineage OS. This ROM is quite famous for its custom-made features from all CM, Lineage, Slim, OFNI ASPA, etc.
The ROM was developed when Google released the code for Android 7 .1 Nougat. In the purest sense, Asp refers to unmodified ROMs or code from Google.
Press question mark to learn the rest of the keyboard shortcuts Preferably a Marshmallow or Nougat ROM, but Lollipop would be fine too.

This is running parallel with another project that I've been planning for a while now, and will most likely take a while to reach completion. I have inherited my wife's old Nexus7 (2013) and would like to use it for light gaming, browsing, and video watching.
Enable OEM unlock in the Developer options settings on the device. You can confirm this is the case if you see an unlocked icon at the bottom of the Google boot screen during reboots.
Recovery: Download md5: 28bd0fcf9075059913aaadac7559a03c Connect the Nexus 7 (Wi-Fi, 2012 version) to the computer via USB. Open a terminal on your PC and reboot the device into fast boot mode by typing ADB reboot bootloader or by using the hardware key combination for your device while it is powered off.
If you see “no permissionsfastboot”, make sure your Dev rules are set up correctly. Once the flash completes successfully, reboot the device into recovery to verify the installation.
Continue to hold all three until the screen flashes, then release all buttons. Download the Cyanogen build package for your device that you’d like to install to your computer.
Note: You can copy the .zip packages to your device using any method you are familiar with. The ADB method is used here because it is universal across all devices and works in both Android and recovery mode.
Continue to hold all three until the screen flashes, then release all buttons. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
Once installation has finished, return to the main menu and select Reboot, then System. These instructions will hopefully assist you to start with a stock Nexus7 (Wi-Fi, 2012 version), unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for Cyanogen (based on Google’s Android operating system).
While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.
It’s pretty satisfying to boot into a fresh operating system you baked at home :) And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want.
Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you. A Nexus 7 (Wi-Fi, 2012 version) A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable cache or build for multiple devices).
Using SSDs results in considerably faster build times than traditional hard drives. A USB cable compatible with the Nexus 7 (Wi-Fi, 2012 version) (typically micro USB, but older devices may use mini USB or have a proprietary cable) A decent internet connection & reliable electricity :) Some familiarity with basic Android operation and terminology.
It would help if you’ve installed custom ROMs on other devices and are familiar with recovery. A 32-bit Linux environment will only work if you are building Cyanogen 6 and older.
If you’ve already installed Cyanogen or another ROM on your Nexus7 (Wi-Fi, 2012 version), your device is already unlocked. The first step in putting any custom operating system on your Nexus7 (Wi-Fi, 2012 version) is to unlock the bootloader.
The bootloader initializes some hardware and then loads the kernel and ram disk, and gets the boot process going. If the bootloader is in locked mode, it will ensure that only the stock operating system can run.
THE PROCESS OF UNLOCKING THE BOOTLOADER WILL ERASE ALL YOUR PERSONAL DATA FROM THE DEVICE. To unlock your bootloader, you’ll first need a program on your computer called fast boot.
Among the many things you can do with ADB– you can push files from your computer to the device or pull files from the device to your computer, you can get a running real-time log of Android activity (which is very useful for debugging or having others help you debug), you can create an interactive “shell” session (similar to Linux or OS X) to type commands to your device, and much more. You can put your Nexus 7 (Wi-Fi, 2012 version) into a “fast boot” mode, whereby, if you are connected via USB cable, you can copy entire partitions from your computer (usually in the form of an image file, such as boot.IMG or recovery.IMG) over to the device, wiping over whatever happened to be there.
It’s also used to send special commands to the device to do things such as unlock your bootloader. Enable OEM unlock in the Developer options settings on the device.
You can confirm this is the case if you see an unlocked icon at the bottom of the Google boot screen during reboots. Troubleshooting If you have issues with fast boot or ADB not being found, make sure that the Android SDK folder /platform-tools, which contains the ADB and fast boot files, are in the path of execution for commands typed at the terminal.
If you have problems with ADB (“file not found”) and you’re using 64-bit Linux (I don’t know much about Mint, so maybe it’s all 64-bit?) If you previously prepared your build environment and have downloaded the Cyanogen source code for another device, skip to.
“SDK” stands for Software Developer Kit, and it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, and more– all from your computer. While the SDK contains lots of different things– the two tools you are most interested in for building Android are ADB and fast boot, located in the /platform-tools directory.
For Ubuntu 16.04 (denial) and newer, substitute (additionally see java notes below): 7 works fine, but the build system will display a warning) Cyanogen 12.0 – 13.0: OpenJDK 1.
7 was removed from the official Ubuntu repositories, you have a couple options: 7 from the OpenJDK PPA Enable experimental OpenJDK 1.8 support in Cyanogen 13.0 (not available in earlier version).
You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). -c will ask repo to pull in only the current branch, instead of the entire CM history.
Prepare to wait a long time while the source code downloads. The repo sync command is used to update the latest source code from Cyanogen and Google.
If you receive an error here about vendor make files, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available.
To do this, you will need to locate your device on Cyanogen’s GitHub and list all the repositories defined in cm.dependencies in your local manifest. If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Env setup help page.
Instead of typing CD ~/android/system every time you want to return to the root of the source code, here’s a short command that will do it for you: crew. You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/ASUS directory.
If this is the case, see the ADB page for suggestions for dealing with “command not found” errors. Nexus users: While it maybe be tempting to run the script on stock Android, and in fact it may succeed, realize that some blobs Cyanogen uses are modified or otherwise different from stock blobs (e.g. Arena graphics libraries).
Save yourself some trouble and install a copy of Cyanogen on your device before extracting blobs. It’s important that these proprietary files are extracted to the ~/android/system/vendor/ASUS directory by using the extract-files.sh script.
Then, specify the amount of disk space to dedicate to cache by typing this from the top of your Android tree: If you plan to build for several devices that do not share the same kernel source, aim for 75 GB-100 GB.
See more information about cache on Google’s android build environment initialization page. If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android cache independent (because it’s huge and can slow down the efficiency of cache in your other projects).
If the build doesn’t start, try lunch and choose your device from the menu. If the build to fails while downloading Hello, you’ll need to import a missing certificate into Maven’s trust store.
Open a terminal on your PC and reboot the device into fast boot mode by typing ADB reboot bootloader or by using the hardware key combination for your device while it is powered off. If you see “no permissionsfastboot”, make sure your Dev rules are set up correctly.
Once the flash completes successfully, reboot the device into recovery to verify the installation. Regardless, the file name will end in .zip and should be titled similarly to official builds.
Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt.
