Note: I apologize that this is so long, but I argued with myself that three
separate posts would be harder to track down for users who need the info. Also,
I don't apologize for writing in a way that I hope anyone can follow and
understand. Please let me know of needed corrections or additions.
ClockWorkMod (CWM) is a valuable tool for loading software, installing ROMs and
troubleshooting on your G-Tablet.
Please note that for the purposes of this guide, ClockWorkMod (CWM) is referring
to "v.8" or what sometimes is called legacy CWM. Do NOT use newer versions or
Rom Manager with the G-Tablet as these will cause problems and varying results.
Also do NOT use CWM (any version) on the new 1.2.4349 update until the gurus sort
out the new software as it will semi-brick your tablet.
The G-Tablet uses a recovery process to work. When you install CWM, you are replacing
that recovery software which means you will not be able to do OTA (over the air) updates
any longer. Also, installing updates manually or installing other ROMs most of the time
will overwrite your CWM and return you to stock recovery.
Be warned: CWM is for advanced users.
Credit for this tool should go to Bekit, to Koush for the custom recovery to start with, and
Roebeet for packaging the update.zip.

Installing ClockWorkMod via Internal Memory ( /sdcard)
To install CWM via Internal Memory, you will need to use the USB cable that came with your
G-Tablet to connect to your PC. In Windows, when you connect the connection will be listed
on the USB/Green Check icon on your Task Bar in the lower right corner of your screen. It
will say "Eject Nvidia Harmony" -- and a Window Explorer Box will appear on your screen. Choose
"Open Folder to View Files."
When Explorer folder opens you will see a listing for "Removable Disk" (on my computer it is G:"
The disk is the internal memory of your tablet known as folder /sdcard.
Follow these steps:
1. Go to the download of CWM from earlier and unpack it so you have a recovery folder with
command file in it and an update.zip file.
2. Copy the folder and file to the tablet disk (/sdcard folder). Then disconnect the USB
cable properly (eject Nvidia Harmony) and shut down the tablet.
3. Boot into recovery on the tablet by holding down the power/volume + buttons together until
you see the "Recovery Key" message in the upper left corner of your screen.
4. You should see a box and progress bar appear while the software is installing.
5. CWM should start and you will see a green menu with ClockWorkMod at the top.
Installing ClockWorkMod (CWM) via MicroSD Card/External Slot
CWM also can be installed using a microSD card and the extenal slot on your G-Tablet.
When the G-Tablet boots into recovery, it checks the internal memory first to
see if a recovery folder with a command file in it exists. If so, it uses it. If not,
then it searches /SDCARD2 (the microSD external card) to see if it is there and
if it has a recovery folder and update.zip on it.
The key to using a microSD in recovery in the external slot is that the command
file has to point to the /SDCARD2 location. You have to use an editor like
Notepad to go into the command file in the recovery folder and edit the
command line to change /SDCARD to /SDCARD2. Works well, but be sure when
you save to keep the file name as "command" (without the parentheses, of course).
And make sure your editor doesn't add a suffix like .txt to it either.
To Make the CWM MiniSD:
1. Download a copy of ClockWorkMod v.8 to your PC.
2. Put you microSD into your PC or depending on what kind of reader/card you
have put it in the carrier/adapter and plug it into your PC.
3. If the download of CWM you have requires it, extract the files so that you
have a recovery folder and an update.zip file.
4. Copy the two files into the root directory of the microSD card.
5. Go into the recovery folder and edit the command file command line to read:
Then save the file making sure the name remains "command".
8. The CWM microSD card will work unless something has messed
up your recovery partition -- so many times you can use it without having to
NVFlash back to stock. Or you can use it to reload CWM after changing a ROM.
NVFlash Procedure to Load ClockWordMod (CWM)
Following is the NVFlash procedure for installing ClockWorkMod (CWM) for those
people who are having boot loop problems (or other problems) and need
to install CWM by flashing rather than by using /sdcard or a microSD card
1. You need to get a copy of ClockWorkMod v.8
2. Once you have extracted the CWM files, go to your NVFlash directory (or whatever
you call it) and make sure you have the right files in it.
-- Nvflash.exe and related files (nvflash_gtablet_2010110500.zip) from
the original NVFlash Recovery thread.
-- USB drivers (also from NVFlash Recovery thread. If you already are
flashing via APX you should have them installed.)
-- The file "nvflash_gtablet.bat" from the NVFlash Recovery thread.
-- The CWM .img file (next item will tell you how to get it.)
3. Next you will need to extract the CWM .img file from the .zip file you
downloaded. First, extract the files from the download -- you should get
a recovery folder and an update.zip. Now unzip the update.zip file and
you will get a file named recovery.img.
4. Rename the file "recovery.img" to "part9.img".
5. Now edit the file "nvflash_gtablet.bat to make the command line read:
"nvflash.exe" --bl bootloader.bin --download 9 part9.img
The command line above for the .bat file does require the quotes around
Or you can simply leave the other .bat file alone and create a new
nvflash_cwm.bat file and put the cwm command line in it if you want to.
6. Boot your tablet into APX mode using power/volume - (you will have a black
screen). Connect the USB cable from your G-Tablet to your PC. If you check
the little USB/green check icon on the PC toolbar (bottom right corner of screen)
you see an APX connection listed.
7. Go to the NVFlash subdirectory on your PC and run the .bat file to load CWM.
8. When the flash is done, use the USB/Green Check icon to disconnect from
the PC and then disconnect from the G-Tablet.
9. Shut down and the boot the G-Tablet into Recovery Mode by pressing
Power/Volume + and hopefully you will see the word "Android" and then the
green CWM menu will appear."
Now you're ready to do whatever you need to do with CWM.
