My G tab will arrive in about a week and i am a total noob.
Ive been trying to get my head around the NV Flash but just isn't going in the eyes and stayin in the brain.

First i can't find a proper link to the files i need not much good on a comp either

When i do eventualy find them do i copy them to my computer then use the USB to flash the Tablet or use wifi???
Sorry for the dumb ass Q's but this is a little over my head which hurts from reading so much.
I think once i get it it will be a lot easier just trying to get everything under control before i try any mod at all!
Cheers all

So heres what you do.. When your GTAB arrives... Go to XDA Developers website.. Find the Viewsonic G Tablet Forums..
Search out NVFLASH.. You should find several forums explaining what needs to be done..

I downloaded all the files, created the folder with the files in it. I run NVFlash, it says everything is good, and then I get stuck ina boot loop till my device powers off. If I go into CWM I tell it to do a cace wipe it never seems to finish. Any idea what I did wrong?

Need help upgrading ROM. Currently has Vegan Tab ROM with Clockwork Mod v2.5.1.1... I followed the instruction on both a Ubuntu laptop and a Windows laptop, got the same results. Populated the nvflash folder with all files. Booted tablet with pwr/vol+, went to clockwork mod screen. connected to laptop and tablet showed up. lsusb showed 0955:7100, instead of 0955:7820 in instructions. On Ubuntu laptop, ran the ./nvflash_gtablet.sh command and it showed nvflash started,,,unknown device found...Done! Windows laptop showed device as USB Mass storage, updated driver and ran .bat file and it errored out.
Do I need to update something on tablet first?

Thanks for the help. Wife's tablet and I don't want to nuke it, make for a bad day.

My Gtab was great, it was using Vegan 5.1. Yesterday, it had some problems,it often force close app ( game, music...). So I went in to CWM and reinstalled rom. But the soft button could not use, I can't do anything in CWM. I holded the power button to turn off my gtab and went I went into Vegan 5.1, the soft button still can't use.
Next, I nvflash and reset factory, my soft button used normanly.But when I reinstalled CWM , the soft button could't use in CWM and stock rom.I tried nvflash with CWM, but it was the same.
Now, when I hold power button and volume+, the soft button can't use in CWM and the stock rom. I often Nvflash and reset factory, but sometime the soft button can use. I turn off my gtab over 6 hours, it is normal.

I would go with an NVFLASH and start over from there.

Go to this site.. (The Name Does NOT Imply Anything about you)
http://viewsonic-gtablet-for-dummies.webs.com/

READ.. Read it again.. Then read it ONCE MORE!..

Goodluck!

Hi Roebeet,

I've successfully NVFLASHed and start CWM to 1.1-3588.every time. However, with every NVFLASH, I never see the VS birds. Every attempt to do a start or a start with the + results in a blank screen.
Every NVFLASH bring up the gtab screen followed by the TNT petals.

I wanted to try flashing with nvflash_gtablet_46_2010112600 but this file does not have a batch file but a .sh extension. I see that this is not a windows but a LINUX protocol.

I don not feel this unit is broken but I sense I'm missing one step before I can get it to start up in the original ROM. May I ask for your thoughts?

Did you start up tablet holding power button and volume- at same time? Screen will go blank but you should now be able to install driver and run NVFlash.

MANY THANKS TO REV FOR RE-WRITING THIS FOR ME, and allowing me to mirror this on Slatedroid!
(Post was updated on 4/22/2011)

=======================================

04/22/2011 EDIT -- I've built out both 1.1-3588-based and 1.2-4349 based versions that have effectively replaced bekit's 1105 image ("nvflash_gtablet_2010110500.zip") - so I am updating Rev's doc with that information. We'll be shoring up this documentation more, in the near future. I updated Rev's documentation a bit. These new images also have working clockworkmod images that you can optionally install, if you want (see the directions below for instructions).

05/08/2011 EDIT -- the 1.2-4349 image has been updated with clockworkmod 3.0.2.8.

05/10/2011 EDIT -- Added a second 4349 image, just for HC testers. It increases the system.img to ~320MB, and reduces the cache partition. Some users might not want to do that for their Froyo devices, so I made this separate.

05/11/2011 EDIT -- Removed the second 4349 image - HC alpha has gotten to the point now where the default image is large enough.

06/17/2011 EDIT -- the 1.2-4349 image has been updated with clockworkmod 3.0.2.8 rev5 (this corrects the nandroid backup issues on rev2)

=======================================

This post is to provide a template for using NVFlash to restore/recover your G-Tablet after suffering some kind of malfunction. Specifically, this document tries to provide ALL the information you need to use the NVFlash tool to recover the 1.1 and 1.2 based software versions, which has been found to be safe as a starting point for rebuilding your tablet after having a problem. This post does not include other methods of setting up NVFlash (such as installing the SDK, etc.) because this method is proven and can be easily supported.

I use Ubuntu Linux and know that the Linux instructions below are correct. Others have written Windows instructions and those too have been checked carefully and have been used before successfully.

A WARNING IN ADVANCE: NVFlash makes changes to the partition structure of your device. You should tread carefully and understand the risks.

The NVFlash setup process begins with a visit to:

http://db.tt/Wm25t7U

(Note: Sometime this DropBox is cranky. If you have trouble with it, check back later.)

Linux users: You want to get "nvflash_linux_2010110500.tar.gz"

Windows users: You want to get "nvflash_windows_20100500.zip"

These are just the OS-specific files for the actual nvflash program itself. So after retrieving the files you need above, you'd then need to retrieve either the 1.1-based or 1.2-based images, here:

1.1-3588 based image: http://www.mediafire...mw1mmifazhmvoeh (updated 4/22/2011)

1.2-4349 based image:
http://www.mediafire.com/?2o6ucnxdc8xh51c (updated 6/17/2011)

-------------------------------------------

Installation

First, create a folder named "NVFlash" on your PC to put the needed files into and to work from. (Note: You can call it something else if you want to; we're just using "NVFlash" to keep all of us on the same page.)

Next, extract the files you downloaded from the DropBox above into the "NVFlash" directory. The files with linux and windows in the middle of then are the files for setting up NVFlash. (The are taken from the SDK and do not install the whole SDK -- just a simple, operable NVFlash for us to use here.) The files with gTablet in the middle contains the .img files with the software to go on your G-Tablet.

Third, for Windows users, you'll need to have an APX-specific USB driver for the next steps. (The Windows package bekit supplied has an .inf file in it, but the actual drivers are not there). For Linux users, you don't need an extra driver.

One source for the Windows drivers is at

http://www.myadventvega.co.uk/

Find the "Downloads" tab in the middle of the page and click on "USB System Driver" to get the files. Extract them and go down two levels to the "USB" folder -- and move that into your "NVFlash" directory. The USB folder has the .inf file for installation in it along with two other directories with drivers for the various operating systems. (Note: These drivers, which are the same as the drivers in the SDK, are proven to work with Win 7 64-bit and have the setup include to load into other versions of Windows.) Follow this narrative for actual installation of the drivers.

CHECKPOINT: At this point, you should have the nvflash files, .img files, and USB directory (and files) in your "NVFlash" directory and are ready to begin the recovery process.

Now, you will need to boot into G-Tablet APX mode: hold down the power and volume - button simultaneously until your G-Tab comes up and the goes back to a black screen. The black screen means it is in APX mode and it is waiting to display the flashing process. In Linux, type "lsusb" in a terminal and you should see this "0955:7820 NVidia Corp.". 7820 means the device is in APX mode.

Connect your G-Tablet to your PC using your miniUSB to USB cable that came with your tablet.

Linux users: At this point, open up a command window to the folder you created, and run this script:

./nvflash_gtablet.sh

This will wipe the device back to bekit's original TnT stock image, except for user data which is retained. Should take about a minute to run and the device will reboot itself automatically. If the script does not work, make sure that the shell script and nvflash binary are set as executables.

Windows users: When you connect to the PC, the PC immediately tries to load a driver -- but since it doesn't know where the USB driver files are it will fail. Click through Start/Control Panel/Device Manager and find "APX" listed in the devices with a yellow "!" (exclamation point) on the icon. Select the APX item and find the "Update Driver" button and click it. When it asks where to search, choose the local computer manual selection choice and tell it to Browse.

Point the Browse (and the USB install) at the "USB" directory under the "NVFlash" folder. When pointed at the "USB" directory, the driver installed and I was ready to nvflash. If you go back to Device Manager after the Windows install has completed, it will show the nVidia USB drivers near the top of the USB device list.

Again, for Windows: Run this script which is in the "NVFlash" folder:

nvflash_gtablet.bat

This will wipe the device back to bekit's original TnT stock image except for user data, which is retained. Should take about a minute to run and the device will reboot itself automatically all the way to the main screen.

POST NVFlash:

When your G-Tablet has booted back to the main screen, you will have to check and make sure everything is set up. Particularly, get the wifi on and connected to the Internet. Almost immediately, you should get a notice about an OTA (over the air) update. This is the OTA Update to software version 3588. If it does, go ahead and have it do the update. From there, you can begin using your "stock 3588" G-Tablet.

If you don't get an automatic OTA notification, you can go the to manual "Update" icon on your tablet and have it check for updates -- and hopefully it will find OTA 3588.

Or, if neither of the above happen, you can download 3588 at the following link and install it manually:

http://tapntap.http....2-3588-user.zip

Note: Following is a STICKY from General Forum on the stock recovery process:

http://forum.xda-dev...ad.php?t=892090

NOTICE: There are many threads out there with tell how to do this process. Others tell individuals' problem solving experiences. A few of them may not be right! The above process is not the only way to do this -- but it is fairly straightforward and it is proven. It is recommended for anyone who does not have experience with nvflashing.

If you borked your recovery, or just need to restore clockworkmod:

You don't need to re-run the entire nvflash batch, to restore clockworkmod. You just need to run one command, after setting up APX mode on your device:

For Windows users: nvflash.exe --bl bootloader.bin --download 9 clockworkmod.img

For Linux users: ./nvflash --bl bootloader.bin --download 9 clockworkmod.img

And then reboot into recovery - it should now work. This is a way to restore a functional recovery if you are flipping between 1.1 and 1.2 ROMs and the recovery is borked afterwards (this is becoming a common issue, lately).

and http://forum.tegrata....bbde76184e550a and http://wiki.tegratab...php/Nvflash_FAQ

Hope this helps!

03/2011 update -- I've been told that this tool has been useful to erase ALL partitions, including user data. I believe you need to re-flash with the bekit 1105 above, AFTER you use this: http://forum.xda-dev...ad.php?t=974422


but
HELP!! I have a GTAB and I am stuck in APX mode. I have downloaded all the files but my windows laptop, but my laptop is not seeing the usb connection. How do I get past this so that can continue on. Thanking all in advance Jaye

Wow! Actually, multiple WOW's, a few to Roebeet first: I had a sinking ship, mod'd months ago to Gingerbread but losing functions -- first I couldn't boot to CWM (despite reloads through ROM mgr), then losing USB link to computer, then "missing programs". Using this post I loaded 4349 + CWM and then on to FlashBack Alpha; without this post I was dead, dead, dead... now I'm rolling along smoothly. Many, many thanks!!

Another WOW to the FlashBack crew. My gods, what a great release HoneyComb is! Stupendous improvements over GingerBread. I'm a little dazed as I no longer know how to find little things like the main Controls, but that too shall pass.

My reason for posting isn't endless praise, however. My experience may be of some use to others, or not. I first tried the earlier version of these instructions at XDA, but I couldn't get 3588 to complete booting after several tries: it just flashed the Tap-N-Tap logo for several minutes and then locked up. Finally, I searched for <this> web page -- which you alluded to on XDA as a later version. Following this page, I tried loading 4349, and then 4349 + CWM, with those same results after several tries... no successful boots.

The Great News, however, was that with CWM -did- load and was working, so I abandoned the 4349 release and, putting HC/FB itself on the SDRAM, had a faultless load. Everything I've tried runs just fine, but the Experience is altogether different. So, two suggestions: something in the instructions isn't clear for some of us retards, so improvements could be made; but, for users who can just get CWM up and running, there's a straight-forward path onward!!!

I've flashed this recovery exactly according to guide, but when I boot into recovery I get "blue" factory recovery mod, not the "orange" CWM. Normal boot is OK. However when I try to install CWM I get stuck in "booting into recovery mod". I tried it several times. I did install CWM initially so I don't think I'm doing anything wrong... Any advice?

Turn it off, try again, make sure you press the power button and plus(+) button at the same time, don't release till it boots into cwm mode.

The one thing I found (since my gTablet came with BL 1.2) was after flashing BL 1.2 with NVFalsh, CWM would not show up. It always booted into stock recovery. I searched and found the thread with the recovery tools which let me switch from stock recovery to CWM via terminal emulator. Once I ran cwmrecovery.sh, everything else worked just fine and I'm loading ROMs without any issues.

maybe it would be a good idea to include the link to the recovery tools thread in the OP?

Hi all, I am not sure if this is the best place(correct forum) for answers, So if not please tell me where to go. (please not figuratively)
I have 2 Gtabs the first is on 1.1, 3588 running Vegan 7.00 RC1, as I have read all kinds of market problems. I thought I might be able to upgrade to 7.1 but it just stays on the GTABEVS screen, so I went back to 7.00 market problem. I have tried the market fix more times than I can count. I have heard that Flashback is good and would like to try that one on my 1.1
What I need is step by step directions that are about flashing a new ROM. I am not sure, because I am not stock exactly where to start. Do I need to repartition, mount/unmount system, data ETC? Do I have to wipe all?
I know these may sound like STUPID questions but I need help. I did find out that Roebeet says you can't go from 1.1 to 1.2 with clockwork, unfortunately I can't figure that one out either.
Any and all help is appreciated.
2. The other is newer 1.2 , 4349. I tried to change the ROM, I NV flashed it, followed all steps loaded the 1.2 ROM Vegan 7.1 it said install complete, the just sat on the blue GTABDEV screen. What the heck am I doing wrong? I have tried Brilliant corners, bottle of smoke and flashback, I either get an error that install was aborted or it just sits after the install. I have given at least 30 min to reboot. I know as a noob I have to be doing some thing wrong. I can not get this one to do anything!!
PLEASE DO NOT ASK ME TO LEAVE I really am trying to learn. I am at the point I can NV FLASH, I seem to be getting very good at that.
This one I would like to watch online movies with, is there a step by step for that?
Once again any and all help is appreciated. and if there is at least 1 other person that is having as much problems as I please let me feel like I am not alone.
Thanking you all in advance Jaye

For #1, the flashback thread has instructions to nvflash flashback on your system. They also give more options. To go from 1.1 to 1.2 takes an Nvflash.

For #2, sounds like you need a cache/ datawipe via clockworkmod as the system is hanging at boot. The install errors from roebeet roms is that he packages his roms slightly different. The downloaded file needs to be extracted (its a .rar) and the update.zip file used to install. Not sure why you get an error on install with a flashback download. At the worst you can nvflash to stock 1.2 4349, wipe data and cache then install the update.zip of your choice

Hope this helps you.
