So, here's a little back story for my frustration.
I asked for the G-tablet for X-mas because of the hardware, and I didn't actually receive the present until just a few hours ago. My PC is refusing to boot Linux at all, so i'm stuck on Win 7, my Samsung Intercept is refusing to root, so no custom rom there... and now I think I broke my G-Tablet.
(I rooted/flashed a ROM on the Vibrant, G1 and mt3g[several times] before this)
I was looking for how to install the custom ROM for the last few days anticipating today, I read Android Police's Guide (it won't let me post the link) several times before actually having the tablet, and I thought I had it down. After installing CW Recovery, I tried booting into recovery mode, which didn't work. It got up to the caution symbol and rebooted. So i figured it could be a boot problem.
I installed ROM Manager because of the useful "boot to recovery" button, but that lead me to the same problem. I looked at all the supported devices on the website and it was listed, but when I tried to flash the ROM inside of ROM Manager, it asked me to confirm if it was a Vega. I was a bit confused with what to do and decided to click accept anyways.
It said it was booting into recovery to complete the process but didn't, so in about a minute, I decided to shut down and boot into recovery myself, and it didn't help. It just cycles though the first two splash screens.
I don't know what to do. =(
Can I somehow hard reset it or something to start over?

Can you still boot into your main ROM or not? IF so, just reinstall recovery - Clockwork Mod 0.8 works, I don't know about later versions or ROM Manager, I don't trust them, based on what I see on the forums.
If you can't boot into recovery OR boot normally, then you have to use APX mode and nvflash to reflash your G Tablet. That completely wipes and rewrites everything on the tablet.
EDIT: If indeed it sounds like clockwork isn't installed and stock recovery is still working, see the instructions in the next post to install clockwork mod 0.8. No need to resort to nvflash.
Step 1.
Download ClockworkMod v08 (This version has been found to work best...the newer version causes some issues with some ROMs.)
The file needed is cwmod_v08.zip at http://forum.xda-developers.com/attachment.php?attachmentid=458883&d=1291787239
Step 2.
Unzip the downloaded file to your microSD card. After unzipping, your microSD card should contain a folder called recovery, and a file named update.zip. (This cannot be done using the internal memory with this download.)
Step 3.
Turn off your device.
Step 4.
Press the power button and the Volume+ button at the same time and release them when the Viewsonic splash screen pops up. You should see "Detect a recovery key pressed" pop up in the upper left corner of the screen.
Step 5.
Watch it install. Your tablet will reboot when installation is complete. And you can access the bootloader by booting the device holding the power and volume+ buttons.

You could become a professional gadget breaker with all the broken stuff you have
Clockwork never got installed if you are seeing the ! and then it reboots. I would not fool with rom manager, or any of the other stuff. Your tablet is NOT a Vega. The vega rom is used as a base to build stuff for the G tablet but it is not the same.
Get clockwork installed. You need to find Clockwork.8 ... You will have an update.zip file, and a recovery folder with a command file inside it. You can install it from the internal sdcard, or an external. You just need to look at the command file with a text editor like notepad and see if it lists sdcard, or sdcard2. If you want to install from internal, sdcard.. From external, sdcard2. The command file does not have an extension. If you do not have one in your clockwork package then download one of the other roms. Most of them will have it. Or even the stock rom package. They are all the same.
Go to SDX and we'll help you with the Intercept. Follow the info hear and the G will be rockin.

I'm pretty sure I wrote that... I don't care that your reposting it...just link where you got it from next time.
Anywho, keep in mind that it's nearly impossible to completely brick these things. Follow this guide, step by step, from start to finish. You will need a microSD card with a way to get files onto it (microSD slot on computer/SD slot with microSD -> SD adapter)

But that's the problem, I can't boot. This is the only thing I've actually broke. =/
I press Vol + and Power, I get the "detect a recovery key pressed", the android screen comes up, and the I get the Yield Sign for about 2 seconds before the boot cycle resets.
I can't get into anything. at all. I thought I was following a propper set of instuctions I'll be glad to follow @scsione889's guide here on XDA, but atm, i can't.

That yield sign is part of the stock recovery, you should still be able to install clockworkmod from microSD. Try it.

If you really have managed to mess up recovery.. You can use Nvflash to get all the way back to stock. Just use caution.. The only 2 tablets I know of that may have actually been completely bricked have been from folks that ran the incorrect batch file in Nvflash... It is really simple to use though... Guide is here...

Yeah, I got it to recognize it, I didn't take recovery and update.zip out of the cwrecovery folder so it didn't work before. I just got it to "unpackage" for a second. but the same boot cycle happened.
I have to run out now for a bit, I'll try the flash later. Thanks for the help so far.
As mentioned before you need a microSD to put the CM recovery on. It also needs to be the .8version of clockwork. AndroidPolice is alright but you really should stick to the xda forums for this kinda thing. It only took me 5 mins to flash clockwork and get the VEGAn build up and running. I wish you the best of luck with your tab. It really is a nifty device....once you're running a custom ROM lol.
Edit: you can hard reset...unfortunately viewsonic failed to make a hole in the case to be able to reach it

Go figure, nvflash won't work because the APX driver won't install and the SDK won't install either because it doesn't recognize the JDK as installed although I installed it like 5 times.
I am a very disgruntled Ubuntu user stuck on Win 7 and I will not take it anymore.

Happy New Year! I hope!
Hello,
I flashed my GTab with TNT Lite a while back, but I was going to switch to Vegan. When I try to go into recovery mode, I get the message in the corner "Recovery Key Detected" but it won't go into CWM. I've got the update.zip and Recovery folder (with command file) in the root of my sdcard. I opened the command file to check the file path, and it's to the internal sdcard, not sdcard2. I even put those files on sdcard2 just in case, but still no go.
Any ideas? CWM 0.8 worked like a charm the first time around when I flashed to TNT Lite 4.2.1, but I just can't get into recovery anymore. I redownloaded it, and erased and put new versions of the update.zip and recovery folder on the sdcard (when the existing ones didn't work), just in case, but still no go.
I can still boot into my ROM, so I also tried "Reboot into recovery mode" from CWM inside the app, but it reboots to the Viewsonic splash screen and hangs there.
Any help would really be appreciated.
Hey, so I ran into the same problem as the first post (with the recycling boot screens). I flashed TNT-Lite onto it, and it worked for a few hours before the problem happened. I NVFlashed it, and at the very least I know the recovery screen is different than after I flashed it, but the yield sign only lasts a few seconds and then the problem persists.
Does NVFlash actually unroot? If so, can I return this to viewsonic and get a replacement? If not, am I screwed?
I got mine running again that same day. I also figured out that the reason Clockwork 0.8 wouldn't work anymore, was because I installed the market version in TNTLite.
But if you follow the NVFlash instructions, start to finish, it should get you back into the original stock ROM. And then from there, you can put Clockwork 0.8 back in place, and re-flash with whatever you want. With the G-tablet, it seems like you gotta go back to stock every time you wanna re-flash, or even upgrade from say TNTLite 4.2.x to 5.x, etc.
Here's the post I followed to NVFlash it properly:

To NVFlash using windows 7 shouldn't be a problem I actually used it today and I'm running windows 7 home edition maybe you need to update your PC and try a linux live CD to run linux on a PC it has more drivers available for equipment and saves someone who doesn't understand linux alot of headache as it uses the CD as your hard disk and it sets it self up just make your system boot from the CD first.

Really it depends on your boot loader branch and its good practice to ensure that everything installs as the Rom develoer intends.

But now I don't touch it and use my tablet or phone 98% of the time. (this is 2% other on an XP desktop)
I also share the same recovery mode issues, but after reading the rest of this topic, I think I might feel adventurous enough to try that honeycomb... >.>
stuck cant get into cwm and is stuck on the tapntap logo
after i nvflash the tablet it wont boot. it gets stuck on the tapntap logo after a few seconds it turns the screen black. and even cant get into cwn it just get stuck on the view sonic logo. i need help
Could I have bricked my tablet? Or could there be a way to recover?
As for what it's current state is; (I am sure is is stuck in the reboot loop) When powering on the tablet, it displays "Android", goes dark, and repeats. Though this is a change from when I was trying to fix it on my own. Before it looping, it would show the "Android" screen and just sit there.
No comes what I think the REAL issue is... Running 'ClockworkMod v2.5.1.1-bekit-0.8', I am unable to mount an external SDcard or mount the USB Storage(text in menu implies to me it is the USB cable to computer).
So other than the images already on the tablet, I seem to be unable to get a new image into it. And of course the images on it don't do any good.

Most definitely not bricked. I've recovered from a much worse situation (bootloader wouldn't even budge - couldn't boot into recovery or regular at all).
Since you are able to boot into recovery, there's probably a way to get things working without resorting to nvflash (we'll get to that in a second - nvflash is the failsafe mechanism, and you should be able to re-nvflash your tablet back to its original state if all else fails).
Here's roughly what I'd try in order:
Option 1) Figure out why you are unable to mount as USB in recovery. I've actually never heard of this problem. Are you using the right cable - i.e. a working USB-to-mini-USB cable (I don't think this works at all with the full sized USB port under the latch cover). Have you tried it with another computer - perhaps there's a driver issue on your PC?
Option 2) If for some reason you really aren't able to get USB mounting working in recovery (I'm skeptical - again, I've never heard of that problem - unless you really did flash a bum recovery image or something - but seems unlikely), then I'd see if you can get ADB working properly when you are in recovery mode. Search around and read about setting up ADB if you haven't already - just a matter of getting the right driver installed on your PC and installing the binary stuff (either from the full Android SDK or one of the packages that just has the ADB stuff floating around). Search the forums, you'll find some references to help you get this working and download the right stuff.
If ADB works, you can always use "adb push filetoflash.zip /sdcard/filetoflash.zip" to put a new file on your internal SD card area and flash it.
Option 3) You can always use nvflash. I'm not going to write up a tutorial on it here - search the forums for nvflash, there are several HOWTOs. Look for the stuff Roebeet posted. You'll need to install the APX driver on your PC first before this will work, and Roebeet's posts don't explain how to install it on Windows, so you'll need to search separately for that. I have gotten this to work before, but it's a pain and I only recommend it if your recovery image is truly trashed or your bootloader is malfunctioning as mine was. In other words, don't bother until you've exhausted the first two options.
So in short - you are in a pain-in-the-ass situation, but you have by no means bricked your tablet - it is very, very far from bricked. Give us more info on *exactly* what happens when you try to "mount as USB" while you have your mini USB cable plugged into the G Tablet - do you see a drive appear on your PC? Are you running a Windows box? Mac? Linux? Have you verified that a USB keychain drive works fine with your PC but the G Tablet won't mount? Basically we need some more info to guide you in your search.
Ok finally had some free time from cleaning/packing and house hunting to try fixing the tablet.
Good news is that I was able to mount the USB. I didn't notice the cat nibble on my cable... So once I dug a spare out, I was able to copy a TnT-Lite image (still had on computer) onto it right quick. Restarted and it installed the image.
So now it has TnT-Lite, though it is weirdly stuck on the setup wizard. It tells me to touch the android to continue and shows an animation of a hand touching the android. But when I touch the android, it turns white and thats it. Also I can change the language to UK or American English. Plus when I press the menu button, I can go to wireless settings, as in cell phone wireless settings. Lastly, I can make an emergency call. So new worthless image. YEY!
I next tried to reboot back into ClockworkMod to see what I could possibly do to get by the lack of continuation in the TnT. But the image install did something interesting. When trying to enter Clockwork Mod, here is what it does from powerup: Displays "Detect a recovery key pressed" then on the next line "Booting recovery kernel image", blanks the screen and then displays "Android" for a few seconds, lastly switching to an exclamation mark in a triangle and rebooting.
So how do I go about screwing it up more?

It almost sounds like you now have stock recovery in your Gtab.
If that's the case, then maybe copy a stock TNT update.zip onto the external Sdcard, and create recovery/command file on there with the string for SDCARD2, then reboot w power and volume+. If you do have stock recovery, that should flash it back to stick TNT. Try Stock TNT 3452, since that'll also flash a stock recovery for sure.

Looks like Brian and I crossposted each other .
For the recovery/command file on the external SDCARD, put the following text in it:

No really, I've Bricked It
So, G Tablet arrived about 5 hours ago. I got it rooted and tried to install CMod 8.1. Things went wrong but I'm not sure what. Anyway, the last thing that I did was to boot in Recovery and then I selected, Format System. Now, when the tablet is turned on, in the top right corner, I have a tiny red message, Magic Value Mismatch. I get this message whether the SD card is installed or not.
I know this information is a little vague but as a Nod, it's all that I have.

I'm only getting the black android screen, I can't seem to mount USB, suggestions?
Ive been stuck right where you are a few times, not to big of a deal, just NVFlash back and start over. I am assuming you are getting the black screen you mention is the APX mode one you get by starting your tab by pressing vol down and power at the same time.
Hi,
My device started boot looping while trying to restore to stock ROM to update to a new ROM.
I wen't through the nvflash process successfully (meaning nvflash wrote the images to the device) but it continue with the loop.
Eventually, it powered down and now it will not power up at all. Battery is fully charged.
Any ideas?
Thanks.
OK, so I figured out that the device was stuck in APX mode.
nvflash doesn't seem to be fixing the problem, so I'm trying adb. It doesn't seem to see the device at all. I'm sure I'm missing step on how to work with adb.
Can anyone point me in the right direction for getting adb connected properly?
Thanks.
I'm trying to get adb working following this guide:
http://forum.xda-developers.com/showthread.php?t=902860
but it cannot see the device. The drive is installed fine but the device does not show up.
I know that if I can get into the device I can put it in debug mode, but I'm not sure how to do this now. I'm thinking this could be my problem, that the device is not in the correct "mode"
Any ideas?
Thanks.

I've been able to do that a couple of times, but after nvflash completes, just get into a TapNTap logo loop and eventually just powers down. When I am able to turn it back on, it goes straight into APX mode.

This is Where I Stand
1. nvflash from TNT lite post
2. Completes and reboots, goes into GTab screen, no Viewsonic screen
3. TapNTap screen and then to n animation
4. Reboot and go to #3. Haven't counted but at some point it just powers off.
I have tried installing CW from the external SD card but cannot get to it.
Have tried adb but cannot get it to connect.
I'm totally out of ideas...I'm thinking that if I just let it sit there, it'll just work

Finally Worked
I have no idea what made it work.
I decided to just take a break and left the tablet connected to the computer through USB but powered down. Came back a couple of hours later and when I turned it back on, I got the Viewsonic screen.
After that, I was able to reboot and go into CW and do a factory reset, which put it in a really old version. It was all easy from there.
pgonza02:
As I understand, you can now power off and reboot you GTab.
Can you recall what were your steps to get to this point?
I'm stuck in APX mode for almost a month! I don't know what else to try...
Thanks in advance.
I tried many things, including:
Install CW by replacing the image for partition 9 with the update.zip for CW (basically rename update.zip to whatever the img file is called)
Add CW to external SD card and attempt to reboot.
Eventually I just left the tablet alone and when I came back I turned it on I saw the Viewsonic birds (this seemed to be the key, when it was not working I never saw it)
I read a thread somewhere that mentioned that nvflash has the ability to redirect output through the HDMI out so you would not see it in the main screen. My guess is that what's happening is that the output of something, that is taking time to complete, is going out that way and I just could not see it. By leaving it alone, whatever it was, completed. This is just a guess, maybe someone with more knowledge can confirm.
Sorry I couldn't give you more details.
Boot loop and black screen
I'm having the same problem. In fact, I'm unable to boot into APX mode.
I have the cover off and read about a hardware reset button. I tried pushing the
reset button (k2) but nothing happened. I also read that I can disconnect
the batter. But, I don't see where the battery wire can be just disconnected
without soldering.
Any ideas?
Ok, so first off, thanks to everyone here for all the info that I've already used. Here's hoping you can help get me the rest of the way. My problem is that, regardless of whether I boot simply (just power) or to clockwork (power and +), it always displays the three birds, says "booting recovery kernel image", and then goes nowhere. Here's how I got there.
I just got my gtablet new less than a week ago, and tried following the directions on here to get VEGAn-tab v5.1. Somewhere on my first attempt I messed up, so I used nvflash to wipe everything and start over, following again the instructions on xda. The version of nvflash I used include clockwork mod, if that matters.
So here I'm booting successfully to clockwork, and follow all the steps to install VEGAn-tab. Except, when I rebooted, it always booted me back to clockwork instead of VEGAn, including when I booted with just the power button. And I had no idea why. I left the unit alone for awhile to ponder things.
This afternoon I decide to try and nvflash once more, in case I did something out of order. Turns out that now when I try and enter APX mode (power and -) my computer (Vista) isn't recognizing it (I do get that little connection sound, but no pop-up / identifier in the directory). And yes, when the tablet is connected in APX mode, my driver is installed and looks fine.
What is going on here? Hopefully someone will have some fun trying to figure this one out. Help xda-kenobi, you're my only hope.
I am a noob but I just used nvflash on my tablet yesterday and if I remember correctly you aren't supposed to get a pop up when you boot your tablet in apx mode and connect it to your pc. Your computer will make the connection sound and all you have to do afterwards is open the nvflash folder and double click on the nvflash_gtablet.bat file. I think the only time you actually get a pop up when you connect your tablet to the pc in apx mode is when you do it for the first time and windows tries to look for the driver. Hope that helps you out.
Yeah but...
Yeah, I wouldn't necessarily think that I'd need formal recognition, but when I try to run the .bat file in APX mode subsequently, it tells me that "nvflash configuration file error: file not found" which makes me think it really can't find it for some reason.
uses nflash ..

refer this thing first. I think u did the (installing wrong version of rom for your bootloader kind of mistake)
Assuming that you installed the driver => (check nvflash section about how to install driver), i might want to remind you that apx mode looks blank , u can't tell the difference. But once you run nvflash you should see a line in the tablet in apx mode
Check the site I told you, everything (the stuck in birds thing) is there
Btw, if you happen to able to recover, I would advise you to install Vegan Tab 7.10 by gojimi, it's the stable and updated version of vegan 5.11
Thanks! And watch out for McAfee
Heyall, thanks for the advice pointing back to the dummies site. I cleared all my previous downloads, started from scratch, and have vegantab 7.1 loading now.
One note for others out there having trouble with their computer recognizing the tablet in APX mode - I think my anti-virus (McAfee, don't blame me, it came free from work) was blocking the tablet from linking up. I've had the problem before with McAfee where it'll allow something to link the first time (usually with an online game) but then later will block it, asking for permission.
Anyways, if you're ever in the Ft. Worth area, I owe you a beer. Thanks again
This is old, but I had the same problem and found it in a search. It worked so I wanted to say thanks!
i have a gtab and it is giving me a headache already trying to figure out how to fix it. I have search high andd low for a solution but havent quite found one, yet.
This is my brother-in-laws gtab. For some reason he tried to flash to a different rom and update the tablet. Right now, the tablet won't boot. It gets stuck on the 3 bird screen. If i try to go into recovery, i still get the 3 birds with the "detected a recovery key pressed."
What i have done...well since i can get into apx mode, the first thing i did was flash nvflash 1.1, that should clear things up, then i pushed recovery. But that didn't work, i am still at the same place i started. So i flashed nvflash 1.2, still didn't work. I re-downloaded the files again from different sources and tried it again, and again, and again. I have tried it atleast 6 times but all with the same outcome. I am still stuck at the 3 birds. I tried holding the + while in nvflash to boot into recovery but that didn't work either. I am fresh out of ideas. Everything i read tells me to wipe cache/data, but i can't even get into CW. And nvflash isn't working for me either.
I am still on the same screen, this darn gtab is giving me the bird three times over. so right now i am going to allow the battery to drain then try again. unless anyone can suggest anything that will give me some hope....or even to tell me that i have bricked the "unbrickable."
oh and everytime i do the nvflash the device does not reboot itself...it stays stuck on the "entering nvflash recovery mode / nv3p server"
I had a similar issue with my gtab except I keptrebooting into apx mode. I then downloaded some nvflash from roebert that said deprecated not use (in a dropbox) and flashed that, my gtab came back to life there... funny thing is that I'm pretty sure I ended up on 1.0, luckily I was able to flash came from that and it's all been good from there.
I would say give that a try, then again I'm relatively proud to say I'm a n00b at Modding these things so tread carefully.
PS : as unbrickable as the gtab might or might not be it can (and to me it is) quite frustrating ; so I feel your pain

You're a code red. You've been missing a very important step. Please follow instructions precisely.

I have done every step on both code red and code double red...code triple doesn't apply since i can still get into apx mode. either way, after i flash nvflash the tablet does not reboot it stays at the nv3p server screen. If i turn it off and back on again the birds come out again. i have even held to the volume + during nvflash and it shows the nv3p server, detect a recovery key pressed, and booting recovery kernel, but no go...it's just stuck...i can turn it on and off, i can get it in and out of apx but it will not reboot after nvflash or boot up a rom or clockwork recovery.
btw, i do have my own tablet as well and i ran nvflash on it just for giggles, and it works as it is suppose to. After it flashes it boots up to tap n

Try code detox, you need a pc/laptop and load the proper driver, run the bat file from the directory. This mode completely reload all the petitions and usually fixes the issue. I think your boot petition is toasted.
Good luck.

This is not normal...
I did the detox and i DID get the "magic value mismatch" in the apx mode. But then i loaded the nvflash it is still in the same state as it was before...not loading recovery, booting, i can only get into apx mode...this is really weird..
I did the detox with both nvflash, 1.1 & 1.2, with and without Clockwork, but none worked. I can do the nvflash "format" and i still get the mismatch message but redoing the nvflash to get the tap n tap stock image or heck even not seeing the darn birds it won't do...
I have even taken it apart, let the battery run out, pulled the battery, pressed the reset button...but nothing!
I can't push anything in adb since i can't boot or get into clockwork...i think the tablet is offically bricked...i have ran out of ideas and have read many...i

I just tried ... and no cigar... i can go all the way to step 2.1 but it won't boot to recovery...it stays at the apx "entering nvflash...recovery key detected...booting recovery..."
to me it seems like it is not retaining any of the info that i am pushing onto it...like a "bios" is being reset and not remembering what to do...
A new error message.

Edit: i reflashed nvflash 1.2 and got rid of the error message...but i am back at square one...but taking a look at the error and from what i am seeing the tab is not finding the kernel image to start recovery. but why?
Cannot get NVFlash to "take"

Did you (or anyone else) discover the "secret" here? What did you do?
Unfortunately, I am now experiencing EXACTLY the same issues. My processes have fixed tons of GTabs that people thought were bricked. I *THOUGHT* that there was no way to HARD-brick the device but I may have been wrong!
I really need some help here. Anyone have an answer?
You could install a copy of Ubuntu and try nvflash with that. That would eliminate any possible driver issues since Ubuntu does not require drivers for apx mode. From the error you posted earlier "entering nvflash recovery mode / nv3p server" it would appear nvflash is not actually flashing anything.

Thanks for the comment. I agree about Ubuntu. I use it exclusively - have for a couple years. I did all my testing and attempts with it. I finally decided to build a WinXP machine and I am now trying to use it.
You are correct about NVFlash not saving anything to the device. There is no bootloader and although all of the NVFlash commands are "successful" it just does not save.
When I try to use the external SDCard to run recovery, the GTab does not seem to recognize it. It acts just as if there was not a recovery file on the card.
One thing that seems to give me some hope. I am seeing the USB connection (while not in APX mode) with the Windows Machine. So, I will install ADB and see if I can grab control that way. But ADB is such a bugger with Windows.
