Thank You in advance for any help.
I have a stock GTablet with the latest updates. This morning while watching an mp4 file the tablet powered off.
Now when I try to power on the tablet, the Viewsonic logo appears then the TapNTap starts to load, the N logo apears then disappears then appears again then the tablet shuts off.
I tried wiping/factory reset the tablet but it still does the same thing.
I have no idea how to remedy this.

Try going to the viewsonicgtabletfordummies website. Read the information there (lots of good info) and start at "Code Red" on "Start Here" page. I'm assuming you are on the 1.2 bootloader if you were on the latest stock update. If you don't mind having a non-stock recovery (CWM) use the NvFlash 1.2 with CWM pre-installed, otherwise use the one without. Follow steps 1-4 and stop at ROM (step 5, unless you want to try one of the great ROMs available for the gtablet! I am using Beastly-Clemsyn and Cyanogenmod 7.2 and they work great for me). If you want to install a ROM or want the advanced recovery features you will want CWM installed. For example, this could have possibly been fixed using a backup created with CWM, or with data wipes, etc without an NvFlash. Point is unless you are a "pure stock" type of person or you wish to return the tablet, CWM is a much better recovery.
When the tablet first boots back up (this can take a while the first time) let it sit for a while to rebuild the caches. Then try taking the OTA update again if you don't want to try out a ROM. Don't worry this all looks a lot more difficult/scary than it really is! Just make sure you read everything twice and don't skip any steps.
Thank You for the path to running again. Tried code red but it did not work. Going to try code double red but I need to charge the tablet first.
I think the easiest, but time consuming, way to recover would be to nvflash the stock rom, or a custom rom.
gTablets are good for being able to break, then rebuild.
Thank You again, following the double red instructions worked.

Everything was great.. did the update rebooted gtab worked great. Has always been stock. I shut it down and when I got home from work i hit the power button and I get the viewsonic birds then the tap n tap logo then the n just stays there and that is it has been stuck on the n for hours. I turn it off and back on and the same thing. Any advice would be appreciated.
Thank you
Have the same problem on stock Gtab.Mine gets to the birds and sticks.Tried holding power and volume up at the same time, but won't reset.Can't discharge the battery because it still goes into sleep mode after 10 min.Computer won't read when plugged into USB.Bought on Woot so a return will be a major p.i.t.a. I am new to Android devices
and was just getting enough balls to try rooting and flashing!!! FML
Yea bought mine from woot also... I liked the stock rom was also afraid to try to load a new rom. Looks like I will be sending it back
hvideo1 and sepder,
You have a choice to make. What both of you have is called a "boot loop".
Sometimes they happen because somebody does something wrong -- and
sometimes like in your case they just seem to happen.
You can return them if that is your desire -- or you can try to fix them.
Usually if one partitions the tablet and cleans it up, it can be fixed. But
that means you have to do some quick learning.
First, you have to get back to a fully stock, hopefully working version. Look
at the following procedure -- which we wrote hoping everyone would be able
to understand and use:
http://forum.xda-developers.com/showthread.php?t=861950
If you complete this procedure and the reflashed stock version works, then
we can load a program called CWM and do the partitioning and cleaning. If
the boot loops persist, then a second choice is to nvflash CWM and use it
to partition/clean up.

The threads above give you more info on the various procedures.
Post back here what you decide to do or if you have questions.

I would try a simple data wipe first. Much easier and less invasive.

Thanks for the replies. I don't want to send my gtab back so I'm reading both post and going to see what happens. I will reply back (hopefully with the gtab) Thanks again
I'm in the same boat as hvideo1 and sepde
Already tried the nvFlash first method mentioned by butchconner but can't get past the "Booting recovery kernel image" message, just sits there on the viewsonic splash.
Going to read and try the "CWM and do the partitioning and cleaning" next.
Appreciate everyone's help!
lrgche,
To NVFlash, you have to press Power/Volume - to activate APX. It will usually come
up with the white screen and then turn black.
"Booting recovery kernel image" indicates you may be pressing Power/Volume + , which
starts up Recovery -- a different process.
Go back through the procedure again and double check that everything is right and
it should work.

This worked for me. Thank you back up and working. the only reason I didn't go the other way was because I didn't understand alot of reading and just confused me (not hard to do)
Lol. Thanks to both of u

Glad to help. You should learn that other procedure if you plan on doing any serious modding in the future though. It may become necessary next time.
Hello, I just bought my G-tablet and I have severely screwed it over. First, I rooted it and installed CWM, (It went fine). Then I flashed Cyanogen 7, following their wiki full update instructions. It was running fine till I found out that for some reason, my computer nor the tablet even knew it had an SD (Computer found nothing, File explorer on tablet had nothing) coupled with the fact Gapps refused to install, I figured this would be solved in a wipe then another flash. Nothing was different. So I wiped again (seemed to have froze during) but the flash of Vegan 5.1 seemed to have went well... for now. However, trying to install Adobe Flash via the preinstalled android market, it wouldn't install. It kept saying download unsuccessful, for every single app I tried. (no it's not an network problem). Being the noob I am I started following random googled XDA threads on how to fix this. I partioned 4gig from my sd to see if that would fix the market problem. I got stuck in a bootloop so I was forced to reflash vegan. When I did, I found out that when I tried to install anything it said something along the lines of "Not enough space" knowing I had 13 gigs of memory leftover, I figured I'd try rebooting. Got stuck in bootloop. Then followed yet ANOTHER googled guide (droidpirate brick fix) and now I can't even access CWM. It just loads as IF it were going to CWM but then shows me a /!\ caution sign then instantly turns off. When I normally start it, it goes into bootloop. when I try to get to CWM (holding volume up, power) it goes to a useless flash that I presume just fails, then brings me back into the bootloop. As far as I see, I have no way of fixing this...
I know this is so much to read, so in a brief explanation.. I'm in a bootloop, cannot get into CWM (brings me to a failed flash then back into boot loop) and am in dire need of assistance Please help me

NvFlash is currently not working for me, I don't know exactly where I messed up but my computer already has the drivers to read the tablet. when I run the .bat, it doesn't seem to do anything.
Scratch that, got it to work. I didn't extract one of the folders entirely. But my tablet is still stuck in bootloop even after this? what now?

Take this with a grain of salt, as I learned it is not 'always' your friend
Now it's just on the stock Viewsonic birds and Gtablet logo bootloop...
Even after I NvFlashed it... Still can't access CMW.
Any suggestions?
Nvm, I got it to what appears to be working. (and I just about jizzed all over my tab.) Thanks so much. Saved me a beating from my parents.

Did you re-flash CWM?
Do you know what bootloader you're on?
I'm not an expert (so take my advice for what it's worth), but if it were me, I'd boot into apx mode again, re-NVFlash it with the version of NVFlash that doesn't have CWM just to eliminate a possible issue. If that works, then I'd either NVFlash it with the version with CWM, or just install CWM.
If you're not sure which BL you're on, I'd just try one, then the other if the first one doesn't work. I've always been very careful about following the instructions about only NVFlashing from OEM 1.1. to 1.2 and vice versa, but yesterday I forgot which version of Clemsym I was on and NVFlash-ed 1.1 over 1.2 aftermarket ROM. So at least in my instance it wasn't the end of the world.
This is the exact issue I'm having. EEK! Trying hard not to freak out.
Glad to have some good responses. Now to figure out where things went horribly wrong. and since the Tablet was originally my husbands, I don't know which OEM it was on originally (and he doesn't recall). Any of the ROMs that have been placed onto it are on both branches.
I've tried re-NVFlashing based on the one I downloaded (from the main thread on the topic). Guess my best bet is to try one from the other branch.
I've tried to look for this problem and haven't found anything similar. If it's already been addressed please direct me to the previous thread, if this is in the wrong place please move it.
I rooted my Galaxy S II a while ago and it's been working great. I wanted to try Cyanogen mod 7 and so I followed the instructions on their website. Trying to use ROM manager gave me a weird error message telling me that there was an invalid signature or something, despite toggling everything and wiping the cache to turn it off. So I followed the "method via recovery" instructions. I did everything exactly as it is there, including the Google apps stuff, and it all seemed to work perfectly. Then I rebooted it hoping for it to boot into CM7, and instead, when it turns on it goes to the screen saying Samsung Galaxy S II with the yellow triangle underneath, and stays there. Every time it turn it on it goes to that screen and doesn't change. It's now been like that for half an hour. I can start it up into download mode, and I've tried flashing zImage to it again, but no change.
I have a NANDroid backup (it's backed up with CWM anyway), and I've copied the backup to my computer, but I have no idea how to apply it when the bloody thing won't turn on.
I'm using Linux with Heimdall (the cross-platform Odin clone).
Please help me. Unfortunately I have no internet in my flat so I won't be able to see any advice until tomorrow unless it;s given in the next ten minutes. God I really hope the thing's ok.
Hi
Do you have jigg? ( if you don't have it buy it from ebay or ask some friend of you )
With jigg you can enter download mode and then flash the stock rom.
Pull battery, wait 10s, then boot while holding power+vol-up+home. This should get you in recovery. Then restore nandroid.

I can't believe it was this simple, I knew power+vol-down+home got tme to downloading but I didn't know that got me into recovery. Everything's recovered now.
Thank you Dutch people!
I received a G Tablet which had been used for development work for a few months. The person giving it to me (not the dev who has left) said the tablet was working fine, but had just become frozen at a reboot after he had tried to erase personal data from the tablet. I asked him if he had erased the sd card and he said "maybe" but that he couldn't remember. I powered the tablet on and sure enough it displayed two lines on a black background, one of which said something like loading kernel.
Now, these tablets were all rooted, and had Android 2.3 on them, via one of the ROMs discussed here. I don't know which one however.
So, I tried using NVflash to flash the tablet back to a stock ROM. Tablet then got stuck in a boot loop; I would see the Viewsonic logo, then the G Tablet logo, and then this would go on forever.
So I shut it down and tried again. This time Nvflash failed almost at the last step after having written most of the image.
And so here I am now, with a totally dead tablet. I cannot power it on. No combination of power or volume up/down buttons work. The only sign of life is when I plug it into its charger, and see the charging light come on.
I confirmed again with the person who gave me the tablet that the device was working just fine before it froze at a reboot after his erasing attempts.
Is there a way out of this? I hope so. Please help!
Thanks very much
Paul

I would try popping it open and unplugging the internal battery then plugging it back in. Also hit the internal reset button while you're in there. It's pretty hard to actually kill one of these tablets. PM me if you need any other help.

Started my own thread, didnt mean to hijack. =)
Thanks, I will try removing the battery and let you know.
As for NVflash, I believe the latest version is here:
http://www.slatedroid.com/topic/171...-using-either-11-or-12-based-images-g-tablet/
However in my case I have no idea whether I have 1.1 or 1.2 and there is no way to determine this. Which one should I choose?
Paul
Doesn't matter for NVFlash, just download all of the flash files again because it might be that you have a bad download. Also make sure you have the right drivers installed since the drivers that automatically install when you plug it in sometimes don't work.
I'm pretty sure that if it boots past the birds, the hardware is working okay, so you should run the FORMAT version for NVFlash and then I'd run just a CWM flash setup and see if you can get into CWM and delete the partitions from within that.
The best thing to flash as far as ROMs would be Bekit's 1105 which is stock OTB with a few key changes. If you can't get the 1105 to play nice, you might really have some hardware problems.
I would go with the 1.2 BL, it will give you access to the newer roms as it appears that dev for the 1.1 BL seems to be dwindeling. I upgraded mine to 1.2 the other day and it worked great.
