[7" Kindle Fire HD Q&A, Help & Troubleshooting] prokennexusa:
Root and Google Play for Amazon 7" Kindle Fire HD Software Version 7.2.3

I hope this helps. The following is step by step.

The problem "Device not Found" is usually driver related or ADB Security issue. I assume you have ADB enabled under Security - Enable ADB? Also enable "Allow Installation of Applications" under the Device tab - this will allow installation of Google Play applications. If all OK, move onto the next step.

Next, as per the Qemu thread noted here http://xdaforums.com/show....php?t=1893838 you will find a driver package named "Kindle_Fire_HD_ADB_Drivers.zip", be sure to install the ADB driver package. Reboot the PC and next the Kindle.

As you noted, if you want to use Google Play, you must Root the device. Just to keep everything consolidated, I will give you a brief Rooting instructions which works for Software 7.2.2 and 7.2.3.

Open the Windows Task Manager. Review the Processes. "End Process" on any adb.exe running. If you installed the Android SDK, there is probably a PATH Statement pointing to the platform-tools folder. To avoid adb.exe start-up conflicts, temporarily rename the SDK platform-tools folder to platform-tools-temp.

Download Root MANY ANDROID! to your desktop. Extract to your desktop. This package includes updated adb daemons.

Download Qemu automated root to your desktop. Extract to your desktop. This package includes updated adb daemons.

NOTE WINDOWS 7 USERS: You need to open a command prompt "as Administrator" when running the above utility batch files RunMe.bat and RootQemu.bat - otherwise Windows will respond with "Permission Denied".

Root Step 1: Run RunMe.bat from Root MANY ANDROID! http://xdaforums.com/show....php?t=1886460. Choose option 1 Run Normal Method and ignore errors. Pay attention, you will need to answer "Restore" a dialogue box on the Kindle. Click on Restore. When the program has completed, the Kindle will Reboot.

Root Step 2: When the Kindle reboots it will react VERY slowly, this is normal - leave it alone. Immediatly proceed to Step 3.

Root Step 3: Run RootQemu.bat from Qemu automated root http://xdaforums.com/show....php?t=1893838. Follow the instructions Step-by-Step allowing Windows to re-detect the Kindle between reboots (about 2 minutes). Let this utility complete to the end.

Root Step 4: Click on Superuser.apk under the Apps tab.

You should now have root AND if this is true your ADB communication is also functional. Finally to Google Play.

Play Step 1 Move GoogleServicesFramework.apk, AccountAndSyncSettings.apk and GoogleLoginService.apk to /system/app. Using Root explorer app on the Fire (be sure it has Superuser Permissions). Change permissions on both to Owner: Read-Write, Group: Read and Others: Read. Install both GoogleServicesFramework.apk, AccountAndSyncSettings.apk and GoogleLoginService.apk

Play Step 2 Reboot the Kindle

Play Step 3 Download Vending.apk

Play Step 4 Using Root explorer app on the Fire (be sure it has Superuser Permissions). Move Vending.apk to /system/app with permissions set to Owner: Read-Write, Group: Read and Others: Read.

Play Step 5 Install Vending.apk

Play Step 6 Google Play should show up in your Kindle Fire HD Apps. Tap on it and follow the steps.

Play Step 7 Download and install the Gplay3.8.17.apk to upgrade the the android market to the current Google Play market.

Play Step 8 Download google_apps - unzip to /sdcard/download

Play Step 9 Install Google Apps as needed. There is no need to move any of the apps to /system/app, just perform a normal apk install by using Root Explorer to install these apps.

I have provided download links of these above noted files to this thread.

Also, I have organized a few Google Apps & Services then zipped them into a folder you may download here: Google Apps. I have used all these Apps on my Kindle 7" HD successfully.

If you would like to disable the Amazon OTA Updates, delete or move /system/ect/security/otacerts.zip to /sdcard/download - Reboot the Kindle.

Finally, to eliminate Amazon from intercepting any Market requests, thus allowing Google Play to be the default Market move /system/app/MarketIntentProxy.apk to /sdcard/download - Reboot the Kindle
