[G Tablet Q&A, Help & Troubleshooting] mrchew1982:
still no luck!

Thank you very much for the reply. Something new to try! Unfortunately it still freezes up. :confused:

recap:

Downloaded the "bekit 1105" image (nvflash_windows_20100500.zip)from Roebeet's sticky and the windows version of nvflash. Unzipped both into a folder on my desktop. 30 files weighing in at 202MB. (ADX drivers for Windows7x64 were previously manually installed through Device Manager)

Started gtab with "volume-" button depressed. Screen flashed on with Viewsonic logo then flashed off. Attached usb cable. Heard connection sound from Windows.

Opened folder previously mentioned, double clicked nvflash_gtab.bat. Clicked "Run" on warning popup.

cmd.exe window pops up:

C:\Users\Desktop\Desktop\bekit1105>"nvflash.exe" --bct gtablet.bct --setbct --bl
bootloader.bin --configfile gtablet.cfg --create --go
Nvflash started

Press enter to continue:

(did not press key yet...)

turned gtab off using power button. Disconnected usb and pressed key to exit NvFlash_gtab.bat window.

Turned gtab on whilst pressing "Volume-". Screen flashes on then goes blank. Windows plays connect sound.

Ran command:

Tablet shows "Entering NvFlash recovery mode / Nv3p Server". Nothing else happens.

Waited 10 minutes. powered off using button, disconnected USB. Powered back on, Viewsonic logo appears, black bar flashes onto bottom of the screen, and...

Nothing else happens! :eek:

Waited another 10 minutes. Tried to get into recovery mode using "Volume+", still hangs, even with an image on the microsd card. Tried the whole thing over again, still nothing.

The fact that it never reboots after nvflash has me worried that there is something deeply wrong.

Is there a way that I could repartition and totally wipe it via nvflash?

This thing is stubborn! Still hoping to find a solution...

Thank you again for the help!
