HOW TO INSTALL

STANDARD DISCLAIMER:

USE AT YOUR OWN RISK. By running this process, you agree that there is the possibility that you may brick your device. You agree that only you are responsible and no one else is responsible for supporting you if that occurs. BUT, we will try and help you get out of trouble, but you have to let us know. ;) Please note that this process WILL DELETE ALL OF THE CURRENT DATA on your gTablet. Be sure to have a reliable Titanium Backup copied to another media.

UPDATED NVFLASH: http://www.teamdrh.com/DRH-Downloads/DRH_NVFLASH_2013.zip

Windows Users Only.

Make sure your BATTERY IS FULLY CHARGED. Push and hold Power button and Volume- (down) keys at same time. The screen should go blank and you will hear an audible connection sound on PC if successful. XP Users - Go to your Control Panel, double-click System, click Hardware tab, and then Device Manager. Windows 7 Users - Go to your Control Panel, click System, select Device Manager link on left window panel. Under USB devices you should see the Nvidia device in the list registered without yellow exclamation mark.

Open the folder created from the zip extraction and find the file 'NVFlash_gTablet.bat' and double-click. A command window will open. Watch the new command window to follow the NVFlash process. You should see partitions being created and partition images installing. If everything completes as designed, the tablet will restart on its own and auto-boot into recovery.

The first thing you will see in the new recovery is 5 errors. Ignore them for now; they are because the cache partition has not been created yet. Scroll down to "advanced" and swipe right (to select). Scroll down to "partition internal storage" and swipe right 3 times. This will set up the NEEDED partition structure for the G-Tablet.

This next part can be done two separate ways:

The first way is via the external sd-card. Make sure your external sd-card is inserted in tablet and then go to "mounts and storage" / "mount usb storage." Take the ROM from "Extract_TeamDRH-DirtyBean-10.1/ROM" and copy that .zip file to the mounted drive. Eject the mounted drive on your computer and back out to the main menu. From there "install zip from sdcard" and then "choose zip from external sdcard." Browse to the location of the rom and launch the install. You will then be directed through a nice GUI to install the ROM.

The second way is via adb sideload (for those that don't have external sd-card). To install, ADB drivers must be installed first. If on Windows 8 follow this thread to reboot with driver signatures disabled. http://tinyurl.com/b2ukmwu If you are on 7 or lower you can enter control panel and right click on Malata/Unknown Device and browse for driver. Select the android_winusb.inf file located in "NEW_NVFLASH/WINDOWS_DRIVERS/ADB." Once the driver is installed it will be available even through rebooting. After the driver is installed in recovery select "install zip from sideload" and wait about 20 seconds before running the "run_me.bat" file. If all goes well you will see the command prompt box "pushing" the rom to the tablet. If the command prompt box goes away very quickly long press power on your tablet to turn it off and boot back into recovery again. Then reselect "install zip from sideload" and attempt it again. When the rom finishes pushing to your tablet it will auto-launch the installer.

After the ROM is installed power off the tablet and go through the initial first boot. It normally takes around 5min for the first boot and about 30 seconds each boot after-the-fact. Remember as always a bake in period always helps as the tablet is still setting itself up and installing apps. Enjoy!

Linux Users Only.

If a script is giving you "access denied" make sure you give it "execute" permissions. You should use the sudo (root) command with the scripts to make sure everything goes correctly.

Make sure your BATTERY IS FULLY CHARGED. Push and hold Power button and Volume- (down) keys at same time. The screen should go blank.

Open the folder created from the zip extraction and find the file 'nvflash_gTablet.sh' and double-click. A command window will open and click run in terminal. When prompted for sudo password enter it. Watch the new command window to follow the NVFlash process. You should see partitions being created and partition images installing.

Final Thoughts:

This build has been tested and running on some "unbootable" tablets. This is not a guarantee this ROM will work on your tablet. I said it before, but if you're not comfortable on using the DRH in the case of a hard lock up, don't flash this amazing ROM. Also this ROM is still going through the testing phase so there is most likely to be bugs.
