[Shield Tablet General] stanglx:
Thanks! Wish you made this thread 2 days ago!!! I went crazy finding some of these...

Some suggestions to add based on my journey.. I have added rough instructions which need to be cleaned up.

A. I didnt know to get into the stock android recovery. I went crazy thinking my stock recovery was corrupt.. I reloaded, etc. etc. I finally found someone who set me straight.

Boot into the Boot Loader - Turn unit off. Hold down the down volume then power button.

Boot into the Nvidia Recovery - While in the boot loader select Recovery Mode. When at the "No Command" screen hold Volume Up and Tap Power.

B. I had major issues getting ADB to work when in CWM, Nvidia Recovery or PhilZ. but fastboot worked fine while in the bootloader. ADB worked fine while booted in the OS. Just didnt work while in recovery mode (trying to sideload an image).

Load Nvidia Drivers. There are two drivers that need to load with a single install base. A bootloader driver that is used for Fastboot and the ADB Composite Driver used for ADB while in recovery OR Android OS.

To install the driver:

1. Enable Developer Mode on the tablet - Go into About and Tap the Last selection 10 times.

2. Go Into Developer Mode and enable "Usb Debugging"

3. Plug the shield tablet into a USB 2.0 port

4. Go into device manager

5 Identify the device with an ! next to it. It should say shield tablet OR just a device id

6 Right mouse click and click update driver software. Select Browse my computer for driver software.

7. At the "Browse my computer for driver software" screen click Browse. Navigate to the driver folder (which you extracted from a zip) and allow the driver to load.

To Fix ADB in Recovery or Fastboot driver issues, ADB must first be working while in the Android OS - see above.

(Generally the Nvidia method will work for fastboot and for ADB while in android OS - but some times ADB fails to be recognized while in recovery) -

Fastboot:

1. While connected to the PC Boot the tablet into the boot loader. Go into FastBoot Protocol.

2. Type the command fastboot devices - if your device lists, its working. If not stay in the boot loader and goto Alternate Driver Load Method below.

ADB:

1. While connected to the PC Boot the tablet into the recovery (CWM, Philz, Nvidia). To boot into recovery see instructions above.

2. While in the recovery navigate to ADB side load for ZIP function and go into that function. The tablet should read waiting for command, or sideload zip, etc. Each recovery is slightly different but similar statement will be made.

3. Now that the tablet is waiting for an ADB command follow Alternate Driver Load Method:

Alternate Driver Load Method:

4. Go into windows device manager. Identify the device with an ! next to it. It should say shield tablet OR just a device id

5. Right mouse click and click update driver software. Select Browse my computer for driver software.

6. At the "Browse my computer for driver software" screen click Browse. Click "Let me pick from a list of device drivers on my computer".

10. UNCHECK "Show Compatible Hardware".

11. Under Manufacturer find and select the category Android. Under Model select ADB Composite Driver (while in Recovery) OR Fastboot Driver (while in the bootloader).
