I. Accessing Diagnostic and Recovery Modes
You should familiarize youself with this section before continuing onto root or any other modificantion that you'd like to do.

  • Power off the device
  • Press and hold Volume +
  • Press the Power button
  • Do not let go of the Volume + button until you see yellow letters along the top talking about fastboot mode
APX mode (nvflash)
  • Power off the device
  • Press and hold Volume +
  • Press the Power button
  • The screen will look like it's off and the device is off, plug it into your computer and it should see the device as 0995:7820 NVIDIA Corp.
MDP/Recovery/Download mode
  • Power off the device
  • Press and hold Volume +
  • Press the Power button
  • It will boot and a screen will pop up saying not to power the device off as it's in Download mode
Note: Fastboot mode requires 25% or more battery life, otherwise it will not accept input

II. Installing Windows Drivers
  • Download the LG drivers (http://goo.gl/QWhT4 or http://goo.gl/5mXwg)
  • Install the software package
  • Plug G-Slate into your computer via USB
  • It will ask for drivers to install, you'll need to basically browse to loacation and select the drivers we installed. The file location is: C:\Program Files\LG Electronics\LG United Mobile Driver.
  • Let it finish the install, you should now have all LG drivers installed.
III. Configuring udev Rules
This document will outline how to configure udev to work with fastboot, adb and nvflash. This will allow a "normal" user to have full access to the device using fastboot, adb and nvflash without root access.
You need to have the Ubuntu Linux 10.04+ operating systems (If you use Windows, may be installing the virtual machine; Download: VMware and Ubuntu 32 bit)

Create a new rule for udev to use:
sudo gedit /etc/udev/rules.d/99-android.rules
(Use whatever editor you'd like. I prefer vi, but for the fairness of being noob friendly, I'll do gedit.)
Insert the following code:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1004:61f9"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0955:7820"
TEST=="/var/run/ConsoleKit/database", \
RUN+="udev-acl --action=$env{action} --device=$env{DEVNAME}"
Save the file.
Reboot the computer.

IV. Configuring MTP Support
You need to configure MTP to mount the SDCARD of the G Slate automatically when plugged in to the computer.
You need:
Ubuntu Linux 10.04+
USB Cable
Terminal or Terminal Emulator
Root or Sudo access
udev Rules configured
  • Do the following in a terminal or terminal emulator.
    sudo apt-get install mtpfs
    sudo mkdir /media/gslate
    sudo chown $USER:$GROUP /media/gslate -- (YOUR USER AND USER GROUP, so: sudo chown myuser:myuser /media/gslate
    sudo gedit /etc/fstab
    Insert the following into the fstab file:
    # mount point for LG G Slate
    mtpfs /media/gslate fuse user,noauto,allow_other 0 0
  • Edit the fuse.conf to allow other users:
    sudo gedit /etc/fuse.conf
  • Uncomment the following line by removing the #:
  • Add your user to the fuse group in the group file:
    sudo gedit /etc/group
  • Edit this line, add your user name after the last : (Colon):
  • Reboot your Computer.
Now when you're done booting, you should now notice a new mount labelled gslate in the Places Menu. Anytime you plug in your G Slate, it will automatically mount and launch a new window that will be mounted to /media/gslate.

V. Manually Install 3.1 Update
Note: Backup your data. If not, it's your own fault if you lose anything.
This section will describe how to install the latest patch from LG and T-Mobile, version 3.1 manually.

Hacky Clockwork Recovery: http://goo.gl/7MlyR or http://goo.gl/3BjkS

You need:
  • USB Cable
  • Terminal or Terminal Emulator
  • Root or Sudo access on workstation being used or udev rules configured

Let it flash, it will take about 15 minutes, then:
Go Back
Go Back
Reboot System Now
The system will reboot to a "Downloading Now" screen. Let it finish, and it will reboot.
The initial boot can take up to 15 minutes, once it boots successfully, it will reboot one more time.
Congratulations, you have upgraded to 3.1.
If you would like to root, please see rooting for multiple options.

The OTA requires 70% or more battery life.
fastboot mode requires 25% or more battery life, otherwise it will not accept input.
Update locks the bootloader, so if you want to remain unlocked, avoid updating for now.
