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.

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)

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.

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.

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
I followed this guide http://forum.xda-developers.com/showthread.php?t=861950 (Roebeet's post) which brought me back to stock.
However, when I apply the 1.1-3588 the tablet shuts off and is unable to be turned back on. The only way to turn it back on is to run the nvflash_gtablet batch file. At which point a receive a notice saying 'The update to version 1.1-3588' was not successful. Please try again or contact customer support.'
Why is the tablet unresponsive after the failed update? Why must I NVFlash to reactivate the screen?
I searched through the forums for the past hour and although I found similar problems I have yet to run into my exact one. I am hoping to find some help.
Edit*
I have the same problem as another user which can be found here http://forum.xda-developers.com/showthread.php?t=903684
I can NVFlash the stock image (or even the NVFlash of TnT-lite 1.02) and the tablet will boot after the flash and function. Power it off (or do something that requires a reboot) and the tablet will no longer function. No power on (that I can tell), can't boot to recovery......and if I plug the tablet in to the PC I can NVFlash it and it boots. It's like it's stuck in APX mode now. I just have to plug it in to the PC, no Power + Volume- combo.....just plug the USB in and run NVFlash. It boots (to whatever I flashed) and will run until I power it off or try to reboot.
Getting APX mode to function is not a problem......so I can NVFlash it but what I've tried so far has not worked (it doesn't delete the data partition, etc..as I reflash and it's right where it was before I turned it off).

The fix posted by acidburn89 was unsuccessful for me
Citi,
I'm not sure exactly what you are doing, but if you are getting the message
you described, that sounds more like you are booting in recovery or a regular
boot and not APX (Power/Volume - to be the white, the black APX NVFlash screen).
My suggestion is to do the stock recovery NVFlash Procedure again. Check
everything step by step to make sure the right files are there and the right
things done.
See if you can complete that and get back to a working bekit 1105 (Stock
Version 2638).
If you can do that, go into Settings/Display and set it so the display does not
turn off).
THEN, if it offers you the OTA Update, let it run.
If it is unsuccessful again, post back here and I will see if I can find the file
and instructions to load 3588 manually.
Hope this helps,
Rev
Ok so I reread Roebeets NVFlash post and double checked my files. All of them are there and in the correct location. I set up my USB drivers, booted into APX mode and ran the nvflash_gtablet.bat
Then the tablet loads properly into the stock TNT 2638. After setting up my WiFi I get a notification that the 3588 update is available. I download the update and after it ask me if I would like to apply now or later. I have tried both options however both seem to fail.
At this point if I hit apply now it shuts down the tablet however it does not turn on. The only way to turn it on is using nvflash_gtablet.bat file. Which it then boots up properly (and it is not wiped, it's as if it is jut turning on normally)and I either get one of two errors.
'The update to version 1.1-3588' was not successful. Please try again or contact customer support.'
or
'The update process cannot proceed due to an unrecoverable error. More information about the error is below, 'Verify checksum: file was not found. Downloaded file does not exist.null'
Hope this helps, I am not new to rooting/flashing roms but this is a completely new error to me.
Citi,
Did you do what I said about setting the display not to go off?
I tell people to do that because I have heard that it can
interrupt the download.
Whatever is happening, it seems like the download is not happening
or not finishing.
You can go to the Developer Forum (or there may be one in General)
and find the thread that tells where to download the .zip version of
the OTA 3588 download.
Then go down to end of the top 4349 thread in General and I wrote a post there for a
guy on how to install an update from the .zip file.

get the recovery.img from from cwm .8 zip file and then use nvFlash to load that.
nvflash --bl bootloader.bin --download 9 recovery.img
(make sure you put the recovery.img in you nvFlash folder and then issue the command above. That will install cwm .8)
from what you wrote above it seems like you are getting stuck in apx mode when you reboot. So my question is what files did you download to setup your nvFlash????

hope that helps...let me know if you stuck anywhere.

Unfortunately I tried out both with the same result
So the problem has changed from not being able to load an update to being in an APX loop? If I understand your original post correctly you were indeed able to nvflash back to original stock and boot normally. Then it failed when you tried to do the update to 3588. If you can still do that...
1) nvflash to bekit's 1105 stock
2) do not install the update
3) clear cache and data with Method I from: http://forum.xda-developers.com/showthread.php?t=1030915 - If this fails due to not being able to enter recovery then your nvflash was no good. You'll need to verify that you have the correct drivers installed, you're using the correct version of nvflash and that your image is sound. Easiest way to do that is to download them again.
4) install ClockworkMod .8 using MicroSD card method.
5) Re-partition 2048 and 0
Were there any error messages in the output of your latest nvflash attempts?
I posted on how you can get cwm .8 installed on your tablet if you are stuck in apx mode. There are also other threads that are pinned under the development section that explain how you can get cwm .8 using nvFlash. You will need that to get out of the apx loop that you are stuck in.

If the screen is blank then connect it to your computer and see if your tablet is in APX mode. You will probably hear the usb connect sound and you can go in device manager to see if it is connected. Let me know and then we can go from there
Yes it has been in a permanent APX mode since my original NVFlash, with the only way to turn the tablet on is to use the nvflash_gtablet.bat file. This will bring the tablet to TnT however my data has not wiped since my original NVFlash and the Wifi and other information is still present. It prompts me to download the new update however there is no need since once the tablet shuts down it will go to APX mode, with a rinse repeat of the cycle and I use .bat file to turn the tablet on.
ok try this...not sure if it will work but its worth a try
1. replace part9.img with the recovery.img ( i m sure u have done this already. this is so cwm .8 gets installed when you do a full nvFlash)
2. when you boot on for the first time.. press the power & + so you go in cwm .8.
let me know if you access cwm .8 if you do this ....we'll move forward from there
Failed first time I did it, but I just tried again and what do you know...success, unsure why.
Currently sitting in CWM looking at that beautiful green screen. I am in the IRC room if we could continue there that would probably work better and faster.
ya i m still at work and cant get on irc here :/...but if you are in cwm .8 then first thing i would do is wipe data then clear cache and then clear dalvik...then go under mounts menu and mount all the partiontions and then format all the partitions...once you are done with that i would mount your tablet so you can see is as a mass storage device on your computer and upload stock frimware 3588 on there...
use this link http://forum.xda-developers.com/showthread.php?t=861950 and go down to post nvflash and get the 3588.zip
from the 3588.zip get the update.zip and copy that to your tablet...once u have that go to the main menu of cwm .8 and choose the option to install update.zip form sdcard...i thikn thats the second one down
try that and see if it works...if not then i'll on irc in the evening today and i'll help you out ...dont stress we'll get your tablet up and running again
Ok, I did a NVflash using method on site and now the birds come on then gtab like it going to load and then off. Just continues the pattern. I tried to run Cwm through an eternal sd but it is not picking it up. I hold the recovery key and power button but it doesnt change the pattern. Can anyone help me.
Not enough info to help, but if you are using cwm, then why are you using nvflash? Or vice versa. Nvflash back to 3558.
You need to do a data wipe. Since you're looping you'll need to load CWM during your nvflash. Replace part9.img in your nvflash folder with recovery.img from the ClockworkMod install zip. Then do the nvflash. Then boot into recovery and clear cache, data, etc. When you reboot after that it should work fine.
Similar Issue
I'm experiencing a similar issue after loading Honeycomb. The system ran well for a while, then got stuck at the viewsonic boot screen. Recover does not load so I cannot perform a data wipe. Any thoughts?
You likely need to nvflash.
I tried NVFlash, but my PC won't detect the device anymore either. I also tried CWM for SD, but the tab still just sits at the Viewsonic boot screen
Update
I tried again from another PC and nvflash is working. It appears I have a usb issue on my first machine.
