Default NV Flash -Full factory reset

This is the "when all else fails method". I learned this from Roebeet and Sprdtyf350 over at XDA. I'm basically transferring their instructions over here. So if you want to find the thread of reference, google NVflash full restore.


Here's another guide to NVflash

NVFLASH (thanks to goodintentions from XDA)


Files you'll need:

You will need to download some files. Bekit provided these in his drop box. Here's the link..

Dropbox - nvflash_gtablet - Online backup, file sync, and sharing made easy.

Before doing anything with these files, create a folder on your desktop. I called mine NVflash.

From the link above, I downloaded these two files... "nvflash_windows_20100500.zip" and ""nvflash_gtablet_2010110500.zip".

First extract the windows zip files into that folder you created. You are going to do the same with the gtablet zip. However, the gtablet zip has the files in a folder so you're going to want to take all the files and manually transfer it to that newly created folder on your desktop.

For windows, you will need to install additional drivers so your computer will recognize your gtablet when it's in APX mode. You can find it here.

xda-developers - View Single Post - [STICKY][ROM] nvflash FULL restore, using bekit's original image (Instructions)

APX mode:

Now put your Gtablet in APX mode by turning off the device then turning it back on by holding the volume - and the power button. The viewsonic screen should appear and your tablet should go blank as if it turned back off.

Now plug your gtablet into your computer using a USB cable
Your computer should recognize the new APX device and prompt you to install the drivers.

Driver Installation: (Windows only)

I chose to Install from a list or specific location.
I then checked Include this location
Find the file location where you installed the USB drivers

NVflash:

With your tablet still connected, go to the folder you created where you put all those files. Find the batch file nv_flash bat and double click and you should see your device starting to flash.

It'll reboot and you should be back to stock.

After that, you can start all over and flash clockwork and ROM if you like.

Edit: 1/31/11

Found this post in XDA and it's really helpful. It tells you how to flash Clockwork Mod automatically while performing a NVflash. With this extra step, you can revive your gtablet and have clockwork recovery ready to go so you can reflash a custom ROM. rcgabriel is a regular at the gtablet forum in xda and he is super helpful.

Did you put the G-tablet in APX mode? You should do that prior to connecting it to your PC. So you need to turn off your device, and turn it back on by holding down the power button and the volume - (down). You should see the viewsonic screen come on then turn back off. That's normal. After you see the black screen, plug your device into the PC. Watch your PC, to the bottom right you should see a pop up saying APX. On my XP PC, a dialog box pops up saying that a new USB device and it give me the option to insert a disk or browse the PC to install the drivers manually.

Then follow the rest of the instructions to install the appropriate drivers.

Edit: I found this video in Youtube. I couldn't view it because I'm at work and they block youtube. But maybe this might help.

Just to clarify: do you mean that all the files from Windows.zip and gtablet.zip are mixed together in the same folder, with no separating sub-folders?

Yeah, that's what I did, so all the files are in there together like one big happy family!

I don't have a need for nvflash yet, but I want to have it waiting in the wings just in case. This is my first exposure to Android, to rooting and modding, and I'll probably mess something up at some point. This will be my fail-safe. So far, I've been able to flash the TnTLite Enhancement Pack, TnTLite 4.1 and currently, VEGAn 5.1. So far everything has gone without problems, thanks to the dedicated devs and helpful members such as you. I appreciate all that you do.

You're a smart person to have this fail safe ready because it looks like the ROM development is starting to pick up for the gtablet. The more ROM flashing the dirtier our file systems can get.

So, I finally got it to flash. Now, any time I turn it off, the grab will not turn back on. I tried a factory reset, but, it does not turn back on or, boot in to recovery. Help! I have a couple days before I get my receipt to try and fix

Thanks!

Might be a stupid question but is the gtab charged? I'm also confused when you say "any time you turn it off, the gtab will not turn back on"? Does that mean the gtab is able to power on but shuts off when it goes to sleep? Regarding recovery, remember once you perform a nvflash, your gtab goes back to its original state meaning you do not have a custom recovery like clockwork.
So try holding your power button for 15 seconds without touching the volume controls and see if your gtab turns on. Your gtab might still be in APX mode.

It is on and functioning after nvflash. I was doing a factory reset, because the superuser app was still there. It will not reboot. I will completely recharge it and try it tomorrow. Thanks for the info

Held the power button for upwards of a minute. No luck. I am at a loss. Could it be a bad file somewhere?

Ok, the initial firmware had issues where the device would not power up. One suggestion is to let the battery run completely out then recharge. Check this out.

Just a quick update. I gave up and took my Gtab back to sears. Couldn't find the time to play with it. Told the manager I just wanted a trade. He told me I was outside the 30 day return, but, he would honer it since it was a gift. So, got a ne gtab to start from scratch. At least, I know what NOT to do.

Thanks to the community for all the suggestions

Awww that's too bad. Yeah, word processing on a tablet isn't very efficient. Anyways...this should be easy for you since everything needs to be done on a PC.

Did you download the files that I have on my original post? The files are located on Bekit's dropbox. There's a link. There's two files you need to download. Prior to downloading, create a folder where you'll extract these files into. Doesn't matter what you call it but I called mine NVflash.

Both of these files need to be on the same folder. They are all files.

Try to follow my instructions and let me know if you have any questions.

I downloaded the Froyo Windows XP/Vista/7 msi file.
It seems the file that is referenced here is not posted any longer. Does anyone have it? I have just bought a boot-looping viewsonic g-tab that needs love.

Edit: Before you NVflash, did you check to see if your gtab already has Clockwork installed? I'm not sure where you got your gtab, so if it's used, maybe clockwork is already on your device. Repartitioning your internal SD card might get you out of bootloop without having to NVflash.


Technically you only need the Drivers and blades from XDA posted it here. It appears you don't need to install the entire SDK.

I have not gotten the gtab yet. I'm expecting it in two or three more days. And after all the positive remarks I've read *almost everywhere* about a rooted, rom-modded gtab, I am totally stoked to get it happening.

I've also had an Eken M001 for the last year. It's underpowered, has a lousy touchscreen (resistive), doesn't do video, and has Android 1.6.

I am SO ready to play...
Thanks for your 1) post, 2) help, xmr405o.

Oh and BTW, your sig kills me. I work with a buncha people that have android devices and one lady with iPhone & iPad. I'm thinking of using your sig as mine when I respond to her emails. XD

Got the gtab. No, It did not have clockwork backup and it did need the memory repartitioned. Repartitioning was the key to fixing its bad behavior probs.

Now running TNT lite 5 and clockwork backup.

Damn, it's fast.

Thanks again xmr405o!

So I did all this and bricked my Gtab. I copied on CW .08 first and initialized it. Then did the above instructions and I can not get the tab to power on. It is fully charged. I did this yesterday and then just did it again. Office Dept is going to look at my VERY funny when I return the 2nd one. I'd prefer to avoid the embarrassment and just make this one work. Can anyone help?

Ok, you might be still in APX mode and don't know it. Try holding down the power button only for 15-20 seconds to see if your tablet powers up.

What did you exactly copy? Just the recovery.img file, right? Did you go into the gtablet.cfg file and edit it to say recovery.img rather than partition9?

xmr405o is right. I bought a bricked G-tablet on ebay, and brought it back to life with the nvflash thread. But it wasn't all roses.

It took me about two and a half hours. I kept 1) not knowing what to expect, 2)forgetting a step, and 3) inducing typos.

You *can* do it. Good luck.

Hi there, I am brand new to androids. I just got my G-tab yesterday and today i was playing around with it and after I turned it off. When I went to turn it back on, it wouldn't go past the vegan tab screen and would just turn off. I should probably state that I bought it pre-rooted since I wanted to avoid some of the technical stuff. But today I tried fixing it by doing it a few ways and I think I only messed it up. Now when I press and hold the power plus the vloume it just gives me an error triangle and tries to reboot. But I when I did the NVflash, I didn't do it right for sure. I got the drivers installed but couldn't figure out the directions from there. I'm not even sure I "extracted" the files properly. I know I sound like a moron, but I am really not good with computers. I thought I was avoiding this whole thing buying it pre-hacked. Can anyone help me? I am freaking out! I need everything explained to me like I am a child, which I am sure is annoying to some. Please help me!

What happens when you press the power and the Volume Up key? You should see the Viewsonic Birds and at the top left you should see the words Recovery Mode. Once it says that let it go. The screen should go black with green type. If is says something like Clockwork Mod at the top it was modded using that program. From there you might try wipe data/wipe cache, then restart the tablet again. Since you probably haven't put your settings in you won't be losing much.

Do what luvduchovny said? Don't try NVflash unless you absolutely need to. If you can get into Clockwork mod recovery, looks something like the image below, then you can probably just reload your ROM.

Exclamation Boot up Loop, please help

Hi,

I'm very new to the Andriod, and need help with my G-Tablet. I had flash a custom ROM (Vegan Tab 7), then when I try to format my external SD card, that's when trouble began. I must have made mistake and it it to the Internal SD Card istead (maybe?? not even sure). Anyway, everytime I boot up I would get only to the bootup screen, and it looks like it reboots and cycle thru the boot up again and again.. won't stop.

So I now NVflash it, and it looks like it work, because now the boot up logo is back to the "G Tablet" and the the 3 viewsonic birds, and it would loop thru this as well. I try to go into recovery (with the + vloume) and it detects it and comes up with a traingle with "!" inside and then reboots into the loop again. I'm freaking out and don't know what to do..

Please please please help...

Hi skydragon

Welcome to the forums!

When you Nvflashed, you flashed the stock recovery again. That exclamation mark means it is looking for an update but can't find one.

Anyways, you can try installing clockwork mod again by using the external sd card method. We can then try to reinstall vegan gb again.

First step

Download and extract the update.zip and recovery folder to your pc. Here's the file...

http://forum.xda-developers.com/attachment.php?attachmentid=478614&d=1293950861

-Take those files and put them on your sdcard.
-Take sd card and put it in your gtablet.
-Power on while holding the volume up. Hopefully it'll begin installing the update file.
-After that, turn off the gtablet and power on again holding the volume up
It should take you to clockwork mod. If you get that on your gtablet, then you can save your gtablet.

Since you can't boot up to mount usb storage, you'll have to do it in Clockwork. This way you can download Vegan GB or any other ROM and put them in your internal SD card so Clockwork can recognize it.

Hopefully you have the Vegan ROM zip file, if you don't you can download it here if you want to install Vegan GB. Download this file on your PC.

http://vegantab.gojimi.com/download/VEGAn-GE-7.0.0-RC1-Harmony-signed.zip

To get that zip file on your gtablet,

-Boot into Clockwork recovery,
-Connect your gtablet into your computer
-scroll down to Mounts and Storage
-scroll down to Mount USB Mass Storage (enter)
-You should now see your gtablet connected to your computer.
-Place the Vegan Zip into the root of your internal memory
-Then unmount the USB
-Press back until you get to the main menu of clockwork.
-Wipe data/factory reset - let it finish
-Wipe cache- let it finish
-Install zip from sdcard
-choose zip from sd card
- Find the Vegan RC1 zip
-Let it install, then go back to the main menu of clockwork then reboot system now.

Hopefully it'll be out of boot loop.

Edit: Almost forgot, when you reformatted your SD card, what did you set it up to 2048 and 0?

Hi xmr405o,

Thanks for the advice.. I could not wait yesterday so I did more research and this is what I did..

1. Since I nvflash it with stock (1.0), I lost CWM recovery and could not repartion.
2. I found directions on how to include cwm in the nvflash files. (told recovery.img from cwm and rename it to part9.img and replace it in nvflash diretory).
3. Rerun the nvflash and it work great. boot into cwm recovery and repartion 2048 and 0.
4. now, over air update stock of 1.1-5388 was found but could not install because cwm was installed on g tab. So I sideload and install thru cwm as update.zip and it work and booted ok and back to stock now.

Now have to decide with Rom to go with.. I enjoy vegan harmony and had no problem, but want to try other ROM.. I want something with overclock build in..

Any suggustion is greatlly appricated.

Thanks again

Good Morning fellow Gtabers - Need some help/ advice. - I have been having some difficult times with my gtab lately. I have been trying to install Clockmod v8-gtab for the past few days and have had no luck. I called viewsonic to see if they could assist in finding a work around on getting Google Market installe on the tablet and they would not help at all. - Told me I would be out of warranty if I did it. After trying a couple of times, I ended up bricking my system (I think). Everytime I try to power on it will get to the TapnTap booting part on the screen and start to flash for a few seconds and then power off. I did some searching and came to this site where it gave great step by step directions on Nvflash and fresh re-install. I thought it worked - I get a screen now that has a triangle with an exclamation point in the middle and shuts down again.
Am I doing something wrong - Can anyone help with my situation. I would greatly appreciate it.
Thanks

Hey all need your help on the flip side of this issue. I have downloaded and used the USB drivers and I assume I should see my gtablet as a hard drive... but I'm seeing nothing. I see the NVidia USB driver loaded in my system.. just not seeing anything in my explorer. Anyone else have this problem?

EDIT: Played with it a bit & sawy it load up the Nvidia Recovery USB drivers when I loaded it in, figured I didnt have it in APX mode... but I still wasn't able to see it in explorer... should I be able too?

Thank you Thank you & thank you.
I had done a bad flash & had soft bricked my tablet and was having a mess of a time trying to get nvflash to work.
All the threads I read just talked about plug in the USB Cable , and install APX Drivers when asked, but none of them (or I just kept missing it) stated to use volume DOWN at power up.

I'm back up and booting now

Hi Luigi

Can you tell me which steps you have completed? Most of the time, NVflash doesn't work because the drivers aren't installed or the wrong nvflash files are being used. So if you can let me know what you have done, I'll try to troubleshoot it for you. It might help others along the way.

Thanks!

Edit: Also, let me know what bootloader you are on.

Did you install the necessary drivers? Does your laptop at least recognize it as new hardware?

I'm running Windows XP, when I first tried to NVflash, a setup wizard pop up would appear. Make sure to download the drivers.

This is a total guess but try clicking on device manager and see if there's an option to install new hardware or drivers. Or maybe a set up wizard.

I realize this is am old thread, but after searching Google and forums for a few hours I need moral support if nothing else... I have a new gTab and I am preparing NVflash to prepared for a new ROM, just in case it needs warranty work done in future.

I have downloaded the files indicated at the beginning of the thread, and after switching the tablet to APX mode and hooking up the wire, my Windows 7 64bit PC popped up the message about the driver. So, following the instructions, in the Device Manager I attempted to install the driver I downloaded from the link from bekit's image as mentioned above, but my computer does not recognize them.

Just to mention, I did unzip the files, and have tried both the amd64 version, as well as i386, but none work. Are there updated APX driver files, or an alternate I can try?

Thanks for your help, all!

Have you tried the first link on the first post. I believe there are links to the correct drivers for your PC. It'll take you to a site called Gtablet for dummies. It's a pretty good resource too.

It seems it was a Windows oddity. When I attempted to point the Device Manager specifically at the amd64 or i386 folders, the process failed. When I re-downloaded the files from the gTab for Dummies dite, I told Device Manager to simply go to any subfolders of the unzipped folder and it worked. So either Windows hiccup, corrupted download earlier, or ineptitude of the user were responsible...

Thank you for your help, and quick response!!

Default Oh please, somebody help me!

Hey, so I have had my gtab for a few months now...Did some playing around and put a vegan - gingerbread thing on it (forgive me, totally new to this) and it worked fine up until recently where it would force close everytime I tried to type anything into the internet browser....Now, all of the sudden, my gtab will not boot up...At first it was stuck in CWM in a (bootloop?!?) and I tried everything, repartitioning the SD card, etc....NOW the scree stays completely black, and the light that comes on when plugged in stays red, it's like it won't charge. So now I am in the same boat with the other people who cannot get windows 7 to recognize the device, I tried all of the steps of trying the NVFlash however my computer doesn't give me the option to select a file to open when I plug the tablet in, most of the time it just makes the beep sound and doesn't do anything...I am in need of serious help here guys! Eek!

I'm stuck. I have already done NVFlash once successfully, so I know the procedure. I tried to do it again on the same computer, and on a different one, and I load the windows driver, but when I run the .bat file, it says "Unknown device found".

Not sure what to do next. I need to return this thing to stock to return it to Viewsonic for a screen repair.

Anyone know what I can do to get it detect my device? Please help.

So currently you are not able to get into your tablet? Did you see the first link on post #1?
I would follow those instructions for NVflash because it has newer files.
