[G Tablet Q&A, Help & Troubleshooting] TEK112:
There is more than one way to get to the 1.2 bootloader. Although I appreciate the bold red font, kinda funny. You don't have to nvflash to get to 1.2. I did not. Here are directions from ramerco taken from slatedroid:

Fool proof way to install 4349:

The reason there are so many steps is that they are broken down so that each step is basically one menu action. Follow EVERY step. Yes there are easier ways, this way ensures that your tablet is absolutly stock and wiped of all traces of other roms.

What you need:

1. A g Tablet with CWM 0.8 recovery (doesn't matter what ROM)

2. A stock 3588 image renamed to 'stock3588update.zip' (http://tapntap.http....2-3588-user.zip)

3. A stock 4349 image renamed to 'update.zip' (http://tapntap.http....2-4349-user.zip)

4. A folder called recovery with a file in it called COMMAND inside it with the following line of text:

--update_package=SDCARD:/update.zip

4. Calkulin's Format_all.zip (attached here: http://forum.xda-dev...224&postcount=1)

NB: SDCARD refers to the internal storage. This is how cwm .8 and most 1.1 roms refer to it.

Step 1: Ensure there is nothing on your g tablet you want. NOTHING!

Step 2: Boot to CWM recovery with Pwr and Vol+

Step 3: Go to the "mounts and storage" menu

Step 4: Choose "mount USB storage"

Step 5: Confirm there is nothing you want to save on your SD card. If there is anything you want, save it now.

Step 6: "Unmount" and go back to the main CWM Recover Menu

Step 7: Choose "advanced"

Step 8: Choose "Partition SD Card"

Step 9: Choose 2048M for Ext size

Step 10: Choose 0M for swap size

Step 11: Watch it Partioning SD Card, then when complete once again mount USB storage as in steps 3/4

Step 12: Load onto the SD Card: Calkulin's_FORMAT_ALL.zip, stock3588update.zip, update.zip (this is the 4349 file), the recovery folder with the command file inside it. Your Sdcard should look like the attached screen grab .

Step 13: Unmount and return to main menu of CWM.

Step 14: Choose "install zip from sdcard" then "choose zip from sdcard" and select "Calkulin's_FORMAT_ALL.zip" (this is just a time saver, on later CWM versions this may not work, it is the same as formatting data, cache, system, and boot manually from mounts and storage menu)

Step 15: Proceed with the install, once finished select "choose zip from sdcard" and select "stock3588update.zip"

Step 16: Once it completes, go to the CWM recovery main menu then power off with the power button.

Step 17: Boot up into recovery with PWR and Vol+. This will initiate the 4349 install using the stock recovery.

Step 18: Watch your tablet boot into a bone stock 4349 rom.

An optional starting point for this is to use nvflash (back to stock recovery or CWM recovery) to repartition everything first to make fully sure all partitions are as they should be.

Yes it is faster to use nvflash to go straight to 4349 now that the option is available, but not that much faster. And with so many people on 1.1 ROM's with CWM saying "How do I get to 1.2 ROMs," I think this is a useful guide.
