Installing ClockworkMod Recovery for 1.2 Bootloader


NOTICE: Continue ONLY if you have flashed the 1.2-4349 firmware (bootloader 1.2) using our “NVFlash for Dummies” guide.

If you have the STOCK version of 1.2-4349, it still may not work with some of the newer HoneyComb ROMs for the GTab (system partition must be enlarged to hold their larger files)


We STRONGLY urge you to return here & flash our version (created by Roebeet).

If you have the 1.1 version bootloader, then you must use our “NVFlash for Dummies” guide to upgrade to bl1.2 before attempting to flash Honeycomb. Thanks to Roebeet for his work to make all of this stuff work. Visit his forum post to give him your vote of thanks.

The process below will prepare your GTab for flashing any ROM based on the GTab 1.2-branch bootloader.

ClockworkMod 1.2bl


1. Download the ClockworkMod & ROM files

2. Connect the USB

  • Power on the G-Tablet (if it is not already on)
  • Attach the USB cable from your computer to the GTab
  • Click on the Orange Ball in the notifications area of the GTab
  • Click on the “USB connected
  • ANSWER: “Activate USB Transfer” & “Activate now”
  • If necessary, repeat this step – until the USB connection is recognized

3. Check Your Computer

  • An Icon or a window should appear on your computer desktop, open it and view the files of the INTERNAL MEMORY (14gig) of the GTab.
  • If a file named “update.zip” is on the root “/” of the device, then rename it to updateold.zip.
  • If a folder on the root is named “recovery” then rename it to “recoveryold”.

4. Find Downloaded Files

  • Open the gtab.cwm.??????.rar file.
  • Inside the file will be a folder named “recovery” & a file named “update.zip”
  • Copy both the folder & the update.zip file to the root of the INTERNAL (14gig) memory (DO NOT copy to a folder & do NOT copy to a removable SD card). (Note: If you see a file named “command” then you opened the folder – go back up one level and copy the FOLDER with the file.)

5. On the GTab

  • Click on “Deactive USB transfer
  • Disconnect the USB cable
  • Power off the GTab – by holding the POWER BUTTON down until a dialog appears – select POWER OFF – and OK.

6. Activate ClockworkMod Recovery

  • Hold the Volume plus (+) button and ALSO press the Power button
  • Continue holding BOTH buttons until some small text appears in upper left corner of the GTab’s screen.
  • Release the buttons and the ClockworkMod (CWM) Recovery should execute.
  • If the menu is BLUE, then you must select the “Reboot system” and press the POWER button to install CWM Recovery. If the menu is orange, just go to the next point.
  • ORANGE MENU (see the screenshot above) – Once the GTab boots into the CWM Recovery, a TEXT menu of options will be displayed on the upper left side of the GTab display. The bottom line should report “ClockworkMod Recovery v3.0.2.8 (GTAB 1.2 and NI Adam rev5)” (or newer).
  • Use the volume +/- buttons to move up or down in the list of menu items, click on the home button (NOT the power button as with the stock recovery) to select an item. Finally, use the back arrow to go back to the previous menu.

7. Create Backup With ClockworkMod (CWM) (Optional)

  • From the CWM menu, select “BACKUP & Restore” — then “Backup” & allow CWM to complete the backup process.
  • Press the back key to return to the main menu

8. Clear Data (This will delete all data on the device!)

  • On the Main CWM Menu, select “Wipe data/factory reset” & press home to execute
  • Select “Yes — delete all user data”
  • Select “Wipe cache partition
  • Select “Yes – Wipe Cache”
  • Select “advanced” and then “Partition SD Card” & execute (Answer 2048 to the first and 0 to the second option.)
  • Wait until it is finished – this step takes a couple minutes. Press the back key to return to the main CWM menu
  • The following steps may not be absolutely necessary but they are HIGHLY recommended. If you chose NOT to wipe the device, just skip to the “Connect USB” step.
  • Select “mounts and storage” then “format /cache” and execute
  • Select “format /data” and execute
  • Select “format /system” and execute
  • Press the back key to return to the main CWM menu

9. Connect USB

  • Connect the USB cable between the GTab and your computer
  • Select “mount USB storage”

10. Flash the new ROM

  • On your computer, find the ROM file that you downloaded
  • Copy the ROM file (still in ZIP format) to the root of the internal memory (14gig) of the GTab.
  • In ClockworkMod, select “Unmount USB storage” & execute
  • Remove the USB cable from the GTab.
  • Press the back key to return to the main CWM menu
  • Select “install zip from sdcard” & execute.
  • Select “choose zip from sdcard” and press home.
  • Use the volume controls to locate & select the zip file that you copied to the root & use HOME to execute it.
  • Select “Yes”
  • When the GTab finishes with the installation, it will report “Install from sdcard complete.”

11. Press the back button to get to the main menu & press HOME to “reboot system now

IMPORTANT! If you select “reboot recovery” you may get stuck in a loop of constantly rebooting into CWM!! If you DO get stuck in the CWM loop,  see this thread on XDA: http://forum.xda-developers.com/showthread.php?t=1264507

  • NOTE: It will take from 4 to 7 minutes for the GTab to initialize and open up to the Android “Welcome” screen so BE PATIENT! Later boots take less than a minute.
  • After you log into your Google Acct, Android Market will begin restoring your apps and settings. Continue to BE PATIENT, this process can take several hours. In the mean time, your GTab will be very sluggish and sometimes even NON-responsive. Just let it do “it’s thing” until all the apps are installed. Then it might be good to reboot. After which, everything should be very responsive.

ClockworkMod 1.2branch and your new custom ROM are now installed
