Getting Started

Getting Started

Welcome to N2A!

In order to install N2A Android 4.2.2 on to your Kindle Fire, there are a couple things you need to do first on your Kindle.

Prior to installation, make sure you have at least 500mb space free on the internal storage of your Kindle.

Next determine which Kindle model you have using the guide here: How to tell which Kindle model tablet you have

Once you know which model of Kindle you have, follow the steps below to get your Kindle ready to install Android.

If you own a Kindle Fire Gen 1:
Step 1: Open Settings – Tap Display – Change Screen Timeout to "Never"
Step 2: Take the Kindle back to the main screen


If you own a Kindle Fire Gen 2, HD 7 or HD 8.9:
Step 1: Open Settings – Tap Security – Enable ADB by Tapping On and Saying Yes
Step 2: Open Settings – Tap Display – Change Screen Timeout to "Never"
Step 3: Take the Kindle back to the main screen


On your Windows based computer, run the N2A Compatibility Checker to detect the Kindle or launch the N2A Installer to begin your installation. Once you have installed the N2A drivers that the programs prompt for you to install, connect the USB cable to your Windows based computer and your Kindle. The N2A Checker or Installer should then detect your Kindle.

How to tell which Kindle Fire model tablet you have

On each Kindle, you can check the system number to help determine what Kindle model you have. From the main screen, swipe down from the upper right hand corner. Tap the "more" button. In settings, tap on "device" and tap "about": Your system number will be listed. Compare your system number with the system numbers below to determine if you have a Kindle model that is supported for N2A.

Gen1 System Number – 6.x.x - Kindle supported with N2A
Gen2 System Number– 10.x.x - Kindle supported with N2A
Original HD7 System Number– 7.4.x - Kindle supported with N2A
HD 8.9 System Number – 8.4.x - Kindle supported with N2A
New HD7 System Number - 11.x.x - Kindle Not currently supported with N2A
New HDX System Number– 13.x.x - Kindle Not currently supported with N2A

Another way to help determine which Kindle you have is to identify if it has a camera.

Gen1 – No Camera – Kindle supported with N2A
Gen2 – No Camera - Kindle supported with N2A
Original HD 7 – Front facing camera - Kindle supported with N2A
HD 8.9 – Front facing camera - Kindle supported with N2A
New HD7 – No front facing camera or has two cameras – Kindle Not currently supported with N2A
New HDX – Front facing camera – Kindle Not currently supported with N2A

Using the information above, you should be able to find out which Kindle Fire model you have in order to determine if N2A Android can be installed on to your Kindle.

N2A Installer Stuck - Troubleshooting Guide

N2A Installer Stuck - Troubleshooting Guide

If you get stuck while running the N2A Installer, there are several things we can try:

Make sure you are using a Windows based computer. The N2A Installer doesn't work on Mac computer hardware that is running any of the Windows Virtual software on the market today.

Disable your anti virus. We have found most anti virus programs intefere with the N2A Installation process. Disable your anti virus real time protection, then close and restart the N2A Installer.

We have found USB 3.0 ports don't support the rooting/installation process of Android. Make sure you plug your cable in to USB 2.0 ports or lower. (Most ports on the back of computers are USB 2.0)

Not all USB cables are the same. If the installer finishes but your Kindle is still in TWRP, try swapping out the USB cable. It is advised to try plugging the cable into a different USB port on your computer as well.

Please disable Bluestacks before running the N2A installer. Bluestacks will cause the Installer to not see your Kindle, even if all the drivers are installed properly. In technical terms from our lead developer: "It causes the adb commands to fail because it can't work out which device to connect to, it sees bluestacks as another android device and then fails."

If all else fails, we have found switching to another Windows based computer can sometimes be the easiest thing to do. You can access the N2A Installer from your account under the "My Download" tab located at the top and download it to any computer on the internet.

N2A Installer - Stuck at download screen

N2A Installer - Stuck at download screen

The N2A Installer has to download the rom for your device via the internet. A stable connection is required to capture the full file. If you encounter a download error during the download process please wait a few hours and try again. If you can't get the download to start please join us in live chat. We can provide remote support and upload the file directly to your computer!

If you run the N2A Installer and it gets stuck at the downloading screen after the download bar has completed. Yet the screen remains sitting at the download screen for longer than 5 minutes, perform the steps below to resolve the issue.

Close the N2A Installer

On your computer click Start - Computer - Local Disk C: - Users - Your "username" folder - then open the folder ".android"

You will see a file, adb_usb, double click on it to open it up.

It should say 0x1949, if it does not, please add that on its own line and click save.

Run the N2A Installer. It should then move forward past the download screen and continue with the install.

How to remove preinstalled drivers XP, Vista, 7, and 8

How to remove preinstalled drivers XP, Vista, 7, and 8

If you are unable to get the N2Aos software to communicate with your Kindle Fire then you will need to uninstall the drivers and try again. For some of you that may be easy, just make sure you check off the box to remove the software too. For the rest of us uninstalling drivers is not a skill we were born with. However, it's super simple if you have the right instructions.

Vista / 7 / 8
- Open Control Panel
- Open Device Manager
- Expand Kindle Fire (or Android Phone)
- Right-click on the name of the driver
- Select Uninstall (check off the box if there is one)
- (if reinstalling) At this point unplug and re-plug the kindle back in and run the installer again

XP
- Open Control Panel
- Open System
- Click the Hardware tab
- Open Device Manager
- Expand Kindle Fire (or Android Phone)
- Right-click on the name of the driver
- Select Uninstall
- (if reinstalling) At this point unplug and re-plug the kindle back in and run the installer again

Why can't I use a Windows virtual machine? (VMware)

Why can't I use a Windows virtual machine? (VMware)

Using a virtual machine of Windows may cause the installation to fail in Fastboot mode which is part of the installation process that the N2A Installer performs. This is due to the fastboot communication connection being lost when the USB controller is handed off to the virtual machine. Your Kindle will reboot into Fastboot mode and just stay there but the N2A Installer will hang at waiting for Kindle.

If this happens to you, reboot the Kindle and take it to a Windows computer and start the installation again.

Where is the N2Aos Installer located for download?

Where is the N2Aos Installer located for download?

With N2Aos you always have access to the latest installer version as soon as it is released. Click on the "My Downloads" link on the navigation bar at the top this page. From there you will see a link labeled "download". Click on it and you will be taken to the most recent version of our installer. If you are looking for Restore 2 Stock or N2A Compatibility Checker, then you will find those at the bottom of our homepage

How do I know if N2Aos is being transferred to my Kindle?

How do I know if N2Aos is being transferred to my Kindle?

One of the steps in the process is to "push" the N2Aos to your Kindle Fire. This step can take 5-25 minutes depending on the speed of the computer and the speed of the USB ports. For instance, USB 1.1 on a Windows XP machine will take considerably longer than USB 3.0 on a brand new PC. The push process does not have its own progress indicator like the downloading process does. If you simply want to see that something is happening you can do the following.

Gen 1: The push happens in Recovery (TWRP) for the Gen1 so you can only see if the N2Aos is there or not. Tap "Install" and look for n2arom.zip on the right side panel. You will not be able to tell the size of the file or if it is growing, only that it is there. Fortunately if the connection is terminated for any reason (USB cable comes unplugged) the N2Aos file will disappear completely from the Kindle. If there is no n2arom.zip in view then you should close the N2A installer application and start again.

Gen2, HD7", HD8.9": The push happens back in Kindle mode for these models. First, unlock the screen and navigate to: Settings > Device > Storage. Scroll to the bottom under "Other" and take a mental note of the size in MB. Back out of the storage settings and then go back in again. The MB should go up by a few. If not, try the back and forth method several more times. If there is still not size increase you should close the N2A installer application and start again.

Windows XP Installation Tips

Windows XP Tips

Due to the fact that Windows XP is nearly 12 years old, it can be a little tricky getting N2Aos installed onto the Kindle. However it can easily be done with a little know how. Here are some useful tips.

1. Verify XP service pack 2 or higher is installed
2. Verify Windows Media Player 11 or higher is installed
3. You will need to install the drivers several times during the process. Do not leave the install unattended. When a driver installation window pops up behind the N2A installer, click next until the driver automatically installs. If after installing the driver the process does not continue, you may need to unplug the USB cable, hold the power button down until the Kindle shuts off, then plug the cable back in. Finally, if the install does not continue automatically, close the N2Aos installer and start again. Since the drivers are already installed, you should not have this problem next time

Bluestacks Program

Bluestacks Program

Please disable Bluestacks if you have it before running the N2A installer. Bluestacks will cause the Installer to not see your Kindle, even if all the drivers are installed properly. In technical terms from our lead developer: "It causes the adb commands to fail because it can't work out which device to connect to, it sees Bluestacks as another android device and then fails."

Other Android Devices plugged in During Install

Please do not have any other Android devices plugged into the PC you will be using while you are running the installer or restore to stock tool The program will get confused and not know where to send commands. This is the same issue that happens with BlueStacks.
