Hi all,
I am a total noob here and i will sincerely hope that you all give me some advice.
I decided to flash ClockworkMod v08 on my gtablet.
However during the flashing process, i think i screwed up somewhere.
I press the power button and +volume until i reached the unloading package symbol. Then i reached a sort of recovery screen with the bottom left saying installing updates.
I waited very long and being impatient i press the restart gtab on the recovery.
When i thought i had successfully installed ClockworkMod v08, I press power button and +volume button and i see the recovery button press and booting recovery kernel image on the 3 birds splash. It loaded for a long time.
I then press the power button and i on the power without the pressing the power and +volume button. I was able to get into the my usual stock gtablet and everythings works fine.
I then reset the gtablet to factory setting on the setting and when i reboot, i was stuck on the 3 birds splash saying booting kernel recovery image. Even when i press the power and +volume button i cannot boot into recovery.
I tried using NVflash but to no avail, my gtablet cannot go into apx and i cannot access my tab.
Please help me help help!
Go to the Viewsonic gTablet for Dummies site here http://viewsonic-gtablet-for-dummies.webs.com/ & folow the instructions.
Here are a couple links with information to help you get your G Tablet restored. The first link in the list is the same one aabbondanza provided. Start there.
If after trying the techniques documented at Viewsonic GTablet For Dummies you still can't get your G Tablet restored, then try following the guide in the second link. I wrote the guide to document the steps I went through to restore a G Tablet.
Viewsonic GTablet For Dummies
Guide - Restore G Tablet after a Failed Recovery Mode "update.zip"
My guide contains some tips and links on APX Mode and NVFLASH.
Hope this helps.

Thanks for the help guys!
After i realised i pressed the wrong button (power + +vol buttons) instead of (power + -vol buttons), NVflash works for me.
However after doing the NVflash, my gtab cannot reboot as in i will need to reboot the gtab with NVflash.
I went to research on xda website and found similar problems.
I managed to solve this issue and will be willing to help out anyone who has this problem (gtab unable to reboot after NVflashing). Just PM me if needed.
Thanks!
VinMee,
I messed up the G tablet big time by flashing a ROM with a different bootloader. I spent many many hours researching posted solutions and trying them out. Towards the end of the process I too could only boot using nvflash. Almost decided to just live with it, but ended up getting that fixed too.
In an attempt to help others I posted the guide referenced previously to detail the restoration steps I used. As mentioned above, I do not need nvflash for booting anymore. When I completed the steps in the guide the limitation was fixed. However, I do not know the "hows" and "whys" behind the fix. For example which step or steps fixed it? Why does the problem occur? Is there a quicker solution if that is my only problem left?
I encourage you to post the fix that worked for you right in this post and include links and/or references to any other posts that helped. Making the information public and readily available is of greater value to someone trying to fix a problem than asking them to PM you and wait for a response. No matter how quickly you respond, it is not as quick as just having the information in the thread. A person could then PM you if they needed additional guidance.
Thanks,

I understand, djab67, and i had posted my solution that worked for me under your thread and i do not have any idea why it works for me but it's worth a try for people who are panicking out there.

I purchased the G-Tablet (GT) from Woot at Amazon and just got my tablet. I opened the box, have plugged in the tablet to charge it, and I've been spending several hours on these and other forums reading and trying to learn as much as I can about the process of taking an "out of the box" GT and getting it to run one of the customized ROMs. I'm amazed at the talent and time being shared to help those of us looking for an Android tablet that really sizzles, but I'm overwhelmed by the amount of information out there.
I have a request that I don't think has been met (in my searches of the forums):
Does someone have a thorough step-by-step tutorial that will help a newbie user who just received a brand new GT in the mail? It seems most of the forum discussions assume the user has already done certain steps, etc. Are there any hold-your-hand tutorials that will go from opening the box to completing the process? (Thanks in advance.)
We (newbies like you and me) are in luck! There are some good tutorials over in the "G Tablet Android Development" section.
Here's a good starter:
Install ClockworkMod, a ROM, Flash Player, and the Market Fix
Thanks for the link to the instructions. Unfortunately, I've run into a problem...
I began with the instructions you referred to and get all the way up to the point where I had installed CWM and VEGAn-TAB Ginger Edition, and I realized in reading a related post that my version might have the 4349+ version with the locked bootloader. When I tried to run the ROM, it froze on the ViewSonic (three birds) screen.
I went to this thread (http://forum.xda-developers.com/showthread.php?t=1036956) and followed the instructions to install the "downgrade" file. This seemed to work well, and I confirmed after starting this downgraded ROM in the GTab's Settings that I was running Tap n Tap 3588.
I then proceeded to reinstall CWM, re-partition the SD card, install the new ROM, clear the data, clear the cached partitions, and clear the Dalvik cache. When I try to reboot to run the newly-installed ROM, I get frozen on the ViewSonic (3 birds) screen again.
Has anyone had this same problem and found a way to fix it? Please help!
Ok...I went back and tried the NVFlash method described here (http://forum.xda-developers.com/showthread.php?t=861950) and then followed the tutorial described here (http://forum.xda-developers.com/showthread.php?t=865245) with success using the VEGAn-TAB Ginger Edition RC1 ROM.
When using the NVFlash instructions, there are a couple of things that gave me trouble with the instructions. First, when it tells you to extract the zipped files to a folder on your PC (named NVFlash in the tutorial), you need to extract to a second level with the nvflash_gtablet_2010110500.zip file so that all of the files - not just the folder - are in the main NVFlash folder you create on your desktop. (If you extract the zipped file to that folder, it simply puts an unzipped folder in there instead of putting the actual files in there.)
The second problem I had was in reading the instructions for putting the G-Tablet into APX mode. It tells you to start up the tablet by pressing the power and volume - button. Since I had been using the Volume + button all night for CWM, I read over the negative sign and had trouble getting the tablet into APX mode. You need to press the power button and the volume down button (the negative side) to enter APX mode.
Once I successfully performed the NVFlash method, I followed the other instructions carefully and am now a happy - and very impressed - owner of a G-Tablet with VEGAn-TAB Ginger Edition RC1!

And that is exactly why I always use Volume Up and Volume Down when I write my instructions ;-) Congrats on getting it working.
Sadly +1, But is was worth it!
Don't feel badly. I did pretty much the same thing. Although a noob to android tab's, I'm pretty good in other tech areas. My real weakness is reading and following instructions correctly the first time!
But, in reality, the read, flash, soft-brick, reread, recover, reread, re-flash...BIG GRINS process has been most illuminating. I really feel pretty comfortable with the processes and the pain points.
This site and the great dev's are truly a wondrous resource. My thanks to all who have contributed to the knowledge base!!

Good Afternoon All,
I'm a complete gtab noob for starters. Anyway, I am attempting to install ClockworkMod v8 following the directions here: http://forum.xda-developers.com/showthread.php?t=865245 but cannot seem to get it to install. I have transferred the files with no problem but after powering off, then "Up Volume/Power On", the screen just remains with the "3 Birds" and -Recovery Key Detected- and -Booting recovery kernel image- messages appearing.
I let it sit for a while the first time, then powered off. I can then power on and get the stock screens with no problem and the tablet seems to work fine. Then I power off and use the "Volume Up/Power On" routine and I just end up getting stuck again.
I have searched around a bit on these terrific forums but just can't seem to find the solution that fits this exact problem.
Any help would be greatly appreciated.
Thanks in advance........

I see quite a few views but unfortunately no replies. Can I safely just delete the files from the root directory of the gtab and place them on an external sdcard and try again or will deleting the files from the root cause another problem?
Thanks to all who have read about my issue. Hopefully we can come up with a solution.

Nearly the same here but once mine shows "recovery key detected", it reboots again and starts normally.
I can get it to boot normally by powering it down and powering it back up. I just can't get ClockworkMod to install no matter how many times I do the "Volume Up + Power Button" routine.
As a result, I am limited as to what I can do with the gtab.....
im having the same problem :/ i really wish i knew why too...i tried it so many times but it gets stuck at booting recovery kernel image
Install clockword
Same problem here it's install,but after the second reboot I can't the clockword menu it's reboot normally
You guys may have 1.2 bootloader. I do not think CWM v8 works with that bootloader. Look around for how to fix your recovery.
I just received my g tablet today (w/bootloader 1.2) and I am having the same problem as the OP. After installing CWM it will boot up normally, but when I try to hold the volume up and power keys to go into recovery it just stalls at the initial 3 birds screen.
I'm a noob and not sure what my options are to get a custom MOD on this thing. Any help appreciated.
Good god. Every thread these days have been talking about 1.1 and 1.2 compatibility. If you have 1.1 use cwm v8. If you have 1.2 use cmw 3028. In addition read second post by moi in the following thread.
http://forum.xda-developers.com/showthread.php?t=1120387
At this point you need to nvflash the appropriate cmw. Go to the following thread.

I have exactly the same problem it sticks at the same place
Guys, you are using the wrong CWM version. Visit my website and use the right version. V8 only works with 1.1 bootloader. You have 1.2. In my website, look at option C. It shows you how to nvflash the right CWM file.

So a buddy of mine bought one of the Viewsonic G-Tablets, and attempted to root(if this is the right term), and I think he may have bricked it. After reading many threads here, and watching some videos, I'm quite confident now that we could get it back to working order, but after hours upon hours of attempts, I cannot seem to solve the issue.
Model: UPC300-2.2
OS Ver: 2.2
Tap UI Version:
1.0-2638
Kernel 2.6.32.9-00000-10.8.2-dirty
Build: FRF91
As of right now, the damn thing will not turn on outside of recovery mode. If you try and power it on, the screen never powers up.
If I power up in recovery, I also don't get a power up screen, until I run NVFlash. After running NVFlash, it will create partitions and boot up into the OS. Every functions at that point, but if I turn it off, and turn it back on, it repeats its previous offense; no screen power.
When I turn it on though, although no power, it does make a bing on my PC, to indicate USB is getting feed, but it does not try and mount the device.
I am not positive what he has done to get it into this mode, or what I can do to get it out of this mode. I've tried a handful walkthroughs and troubleshooting threads but they have not resolved this problem. Is this common? What are my steps to try and resolve it? He's coming up to the end of his RMA time, and he will soon try and see if he can RMA it, so I don't have a lot of time to futz with it, so I'm reaching out for help.
If there is any other information you need, please request, I just posted the basic info I found on the About tablet page
Thanks!
Can anyone confirm if this is an actual boot loop? What would make it so I have to nvflash each time to load this tablet; is it fixable, or is there an issue somewhere else with the device, that may just mean its bricked.
when you try to boot into recovery are you holding the volume up button and the power button at the same time untill it boot into recovery if it does boot then you need to wipe user data and wipe cash if not try to load clockwork mod do a search in the main viewsonic fourm to learn how to do this I hope this is some help Good Luck
I shut it off for the night and went to start it up the next day, but it wouldn't start up. It skips the birds and goes directly to the G-TABDEV5 screen and stays stuck there. The power and volume buttons don't get me into recovery mode. Any clue. I had just installed the new netflix ap was totally enjoying it.
I'm running vegan tab ginger edition.
Thanks in advance

Use the Gtab for Dummies link and start at Code Red!
thank you all very much
I tried the drain battery suggestion and it worked. Thanks again !
My GTab will only boot up with NVFlash in APX mode. It will not power on via the power button, nor with CWM. I just bought this GTab, tried loading CWM and it didn't take (or thought so), so tried to nvflash with CWM and now it will only boot with power and volume(-) into apx. Once it boots, all my files are there. I have tried detox from gtab for dummies. I am guessing my next option is letting the battery drain all the way and go from there? Any help would be great. thanks
PS This is my second GTAB and have experience rooting, and flashing roms.
Not sure what you mean by "it only boots into APX but all my files are there." APX mode doesn't allow access to files as far as I'm aware.
Also you may want to double check the orientation of your vol + and - keys. The gtab for dummies site notes that some models have the orientation switched.
You could try one of these procedures:
1. K J Rad's procedure for unbricking gTabs. (Actually, read carefully through that entire thread.) Follow all steps exactly as mentioned.
2. Childofthehorn's method. See this video:
How to unbrick your Viewsonic G-Tablet by Railfan02.
Yes, I had seen those sources for a solution. After researching and googling, this is what I found and it worked. What I meant by only boot in APX mode is, it only would load a rom via APX and I had to NVFLASH. I couldn't get into CWM Recovery with volume + or volume -, so after searching, this was my first choice and it worked on the first try.

If this didn't work, I was going to try Childofthehorn's option here.

Anyway, I am happy that I got it up and running on Flashback.

That seems to be the procedure figured out by K J Rad some time back.
Holy Crap! This fixed my Gtablet. Awesome.
