I Want to Factory ROM Reset My Google IO Galaxy Tab 10.1, But Fastboot Device Isn't Recognized


By steve - Posted on 04 January 2012

I've posted another article about the Galaxy Tab 10.1 and having a problem with it locking up. I had that happen 3 times, but it always recovered.

Hopeful that the latest OTA (over the air) update would fix that issue, I set the Tab to automatically update. Within 24 hours, the tab was bricked and was stuck in a boot loop of displaying the samsung startup screen, the spinning space screen, then repeat.

I figured the best thing to do was start over. It being a tablet and me being cloud-based, there wasn't anything on the system that mattered, so I didn't do anything to try and save what was on the tab.

There are several ways to reset your tab and they are posted all over the place and easily googled.

However, I did run into a problem trying to get fastboot to communicate on my Windows 7 64-bit install. The tab would boot into download mode, but the device showed up as "fastboot", but no drivers. I tried installing the recommended Samsung USB drivers, but that didn't help. I tried several things until I found the ultimate solution...

I already had the Android developer's environment set up, but I hadn't updated in a while. So here's what I did:

1. Install the Android SDK, if it isn't.
2. Start the Android SDK Manager and update all the packages to the latest release. Make sure you select at least the "GALAXY Tab by Samsung Electronics" API and the "Google USB Driver package, revision x" packages. The Galaxy Tab package may not be required, but the Google USB Driver package will be. It will take a while, but I recommend you update everything.
3. Accept the agreements and download and install the packages.
4. If asked, reboot, restart ADB, and/or restart SDK Manager.
5. Open this file: "C:\program files (x86)\Android\android-sdk\extras\google\usb_driver\android_winusb.inf" with notepad. It might be somewhere else, if you installed it somewhere else.
Add these lines to the [Google.NTx86] and [Google.NTamd64] sections:

;Galaxy Tab 10.1v
%SingleAdbInterface% = USB_Install, USB\VID_04E8&PID_6860&REV_9999&MI_01
%CompositeAdbInterface% = USB_Install, USB\VID_04E8&PID_6860&MI_01
%SingleAdbInterface% = USB_Install, USB\VID_04E8&PID_6601
%SingleAdbInterface% = USB_Install, USB\VID_0955&PID_7000

6. Open "My Computer" properties and select "Device Manager".
7. Right click on "fastboot" (which probably has a yellow warning indicator on it) and click "Update Driver Software Driver...".
8. Click "Browse my computer for driver software" and select the same folder as android_winusb.inf is in (see step 5).
9. Install the driver software, even though Windows can't verify it.
10. At this point, the fastboot warning should go away on the device manager and you should be able to continue with the operations you need to do to be able to reset or update your Galaxy Tab 10.1 device.

So how do you actually stop the boot loop on the Galaxy Tab?

Google around to find out more or you can clear all data and just kill it like this by doing a total system wipe (which is what I did based on what is described here: http://www.galaxytabforums.net/forum/galaxy-tab-10-1-help/885-my-google-... ):

1. Put a recovery.img file in the platform-tools folder where adb resides. The one here: http://droidbasement.com/galaxy/sys-backup/recovery.zip might work for you.
2. Press and hold the volume down (left button in landscape) and power buttons until the usb and odin icons show up. Volume down to move left and volume up to select the usb logo (not the download icon!). Now you should be in fastboot. Plug the usb into your computer.
3. Open a cmd window. CD to your platform-tools folder or wherever your adb is at. (Should be in platform-tools inside of android-sdk-windows.) In my case, that is the directory I showed in the previous section: "C:\program files (x86)\Android\android-sdk\platform-tools\"
4. Run: adb start-server
5. Run: fastboot devices
(You should see your device listed, if it is communicating--if it isn't, fix this before continuing.)
6. Run: fastboot boot recovery.img
7. Boot the Tab into recovery using the volume button to highlight the option and the power button to select it.
8. Do a factory reset. Select: wipe data/factory reset
9. Confirm you want to do that.
10. Select: reboot device
11. Do setup and you are good to go.
