[Fire HD 6 and 7 General] DoLooper:
➜ No big ol’ SDK ➜ Latest Google drivers ➜ No messing with inf files ➜ ADB from any location ➜ Drag and drop files

Figured XDA needed a couple more ADB driver guides, :D so I'm bringing these down from Google drive where they've been getting a lot of use--with no complaints so far. :fingers-crossed:

Follow the steps below to install the Google ADB driver for "normal" (OS) mode.

Follow post #2 to install the driver for sideload mode. You must do this to sideload OS .bin files via stock recovery.

See post #3 for basic info/tips for using the command window and entering adb commands.

[EDIT September 21, 2015] If you're running Windows 10, read this:

At step 3 you install 15 Second ADB Installer. Some Win 10 users are reporting a problem. Please do this to help track it down:

- Be sure to run as Administrator.

- If you get an error, post the exact error and when it happens. Do not rerun Installer until someone replies to post.

- If you do not get an error, please post and say so and tell what type of Win 10 you have (home, pro, enterprise, etc.)

Thanks!

Install ADB Driver for "Normal" (OS) Mode

This uses [MENTION=4638083]Snoop05[/MENTION]'s 15-Seconds ADB Installer. It provides the driver and software you need and puts the path to adb.exe into your PATH variable so you can run ADB commands from any folder.

Before you begin:

(1) Turn off anti-virus software

(2) Disconnect other physical devices that use adb and shut down any virtual ones. This can go very smoothly if you're not running anything that uses adb, including emulators, some photo-sync software, Gatesjr debloater, etc.

1. Make sure adb debugging is enabled on the the device. (Settings->My Device->Developer Options: Debugging)

To open Developer Options: In Settings -> My Device, tap on the serial number until Developer Options appears at bottom of screen.

2. If you've never connected Fire HD to computer, connect now and read this:

a. You may see a USB debugging message on tablet, tap "Always" and "Allow."

Even if you don't see message, Windows should try to install generic MTP drivers (not ADB!). Wait until you see success or failed message.

b. Unplug/replug and wait for Windows Explorer OR for message that prompts what to do when device is connected and choose Open window to Display Files, check Always do this and then OK.

c. Disconnect..

3. If you KNOW there’s no adb driver installed for the device, go to next step.

. . . If driver might already be installed, do hidden steps.

Connect to computer, open Device Manager (instructions below) and see if a driver is listed under Android Device.

- If a driver is NOT listed, go to next step.

- If a driver IS listed, open CMD window in folder containing adb.exe and run adb devices command (step 12).

* If adb devices DOES return an ID, this driver is working and you don’t need to install a different one.

* If adb devices does NOT return an ID:

a. In Device Manager, right-click the driver and choose Uninstall.

b. Unplug the device and restart Windows.​

4. Download the latest version, currently v. 1.4.3, of 15 seconds ADB Installer and run it as Administrator.

If you are not Administrator, right-click the file and choose “Run as Administrator“

Read all about 15-seconds Installer at the link.

5. An Install Wizard will run. Look for it and install device software!

6. Connect the Fire to the computer and wait until you see it in Windows Explorer.

7. 6/3/2016 Update for Win 10: Your drivers might already be installed. Check for Allow USB Debugging on tablet. Go to step 12 and run the adb devices command.

. . . If it shows serial number and unauthorized, you need to enable USB debugging and run command again. It should then show serial number and "device." You're done!

. . .If it doesn't show serial number, continue the steps.

Win 7 and 8.1: Open Device Manager:

Win10: ? Win8: Right-click Start Button and choose Device Manager. Win7: Click Start button and type Device Man [enter]

8. Find Fire under Other Devices, right-click it, and choose Update Driver Software.

If you don't see Fire under Other Devices, disconnect/reconnect or try a different USB port, or try toggling Enable ADB in Developer Options. If nothing works, disconnect and reboot both Fire and computer and try again.

View attachment 3457130

. . . If Android Device is not listed, look here.

If you DID NOT run 15 Seconds ADB Installer, STOP, disconnect from PC and run it now.

If you DID run 15 Seconds ADB Installer:

a. Double-click Show All Devices.

b. Under Manufacturer, scroll to Google, Inc, click it and continue.

↠ If Google, Inc is not listed, the ADB drivers are not installed, they installed incorrectly or were corrupted. STOP now and follow all the steps again.

11. Select Google, Inc in left pane and then Android Composite ADB interface in right, and press Next.

If the screen you see only has the Model pane (on the right above), scroll down to Android Composite ADB.

↠ If the driver is not listed, drivers have not been installed, they installed incorrectly or were corrupted. STOP now and follow all the steps again.
​

12. At the warning screen, press Yes.

Driver is updated!

13. Run the adb devices command and confirm it returns a device id:

a. Open CMD window: Hold down the Shift key, right-click the desktop (or an empty space in a folder) and choose Open command window here.

b. Type: adb devices [enter]

View attachment 3467199

If you see an ID followed by “device,” the driver is installed correctly. DONE!

If you see an ID followed by “unauthorized,” look at the tablet for “Allow USB Debugging?” message and tap OK.

If debugging message disappears before you say “OK,” unplug/replug tablet to see it again.

Repeat the adb devices command and confirm it now looks like above. DONE!

If you do not see an ID, the driver may not be correctly installed or USB debugging might still be disabled on your tablet. Verify all connections and reboot tablet and PC and repeat this step. If adb devices still doesn’t return an ID, follow this guide from the beginning again. :(
