Figured this was better for a new thread (since a few people in the [Solution] How to recover from a 'bricked' gtab! thread have the same issue, and obviously there isn't a solution yet)
So I screwed up and formatted the SD Card, not realizing that on the G-Tablet the SD Card is actually the internal storage. Needless to say it caused some major issues.
Originally I was stuck in an APX Bootloop. Then I NVflashed, and on initial boot it would show the G-Tab screen, TapNTap screen, then the N screen and then proceed to reboot. It would go through this for 5-10 minutes then just go to a black screen.
With all that said, here are the most recent steps that I've used, and been able to boot up normally ONCE (upon restart it boots into APX):
NVflash 3588 w/ CWM
Boot into CWM (holding the Volume + before beginning NVflash)
Format Boot
Format System
Format Data
Format Cache
Format SD Card
Format SDext
Partion SD Card (2048/0)
Fix Permissions
Wipe Data/Factory Reset
Wipe Cache
Wipe Davlik Cache
Reboot
Reboots into APX
NVflash 3588 w/o CWM
Reboots
G-Tablet Screen, then TapNTap screen, then N screen
Boots up the first time fine (into Android OS), but after a restart it only goes into APX.

Is this thing on? Bueller, Bueller?
From reading through some of the other (somewhat unrelated) threads, it seemed like there were a number of people with this same issue. Something is stopping it from re-booting normally. I know there are alot of great minds in the dev section, hoping they can provide some insight on this issue.
Can you get into cwm to repartition the internal SD to 2048 and 0 swap? I think Your SD was formated but not to correct structure for correct boot partitioning.
I ran into a similar issue and from my experience it seems as if each tablet are quite different. If you search through the forums you will see a number of techniques that work for some yet fail for others.
My situation was never fixed and it ended up with me returning my device.
There is some decent information in this thread http://forum.xda-developers.com/showthread.php?t=1038689 however it is spread out through the pages
FIXED IT!!!!!!
Followed the instructions in this post: http://forum.xda-developers.com/showpost.php?p=12220001&postcount=1
Here is what I did step by step
1. Download the 2 attached files below and the top file here: http://forum.xda-developers.com/showpost.php?p=9837354&postcount=3 (rename that file to update.zip)
2. Copy recovery-stock.img into folder that you are running NVflash from.
3. Run NVflash to start the tab, since that is the only way to boot it with the APX issue.
4. Once booted up, Mount it via USB, and copy the attached update.zip into the tablet internal sdcard.
5. Unzip the attached cwmod-internal.zip and copy the recovery folder (including the command file) to the sdcard.
6. Power off the tab.
7. Power on to make sure you enter APX mode (you will see the black screen, but hear a bing sound)
8. Type in the Dos Command: nvflash --bl bootloader.bin --download 9 recovery-stock.img --go (READ BELOW BEFORE YOU HIT ENTER)
9. Press and hold the Volume + on the Gtablet and press enter on the PC to execute the above line. You will see it starts to installing the original rom..(about 3 minutes)..and then power off autmotically after finishing flashing ! Dont worry.
10. Repeat step 7 and 8, and press enter (do NOT hold volume +!)
11. The tab will start to the TnT like the original one you had, and Magic now: you can turn off and turn on the tab NORMALLY!!
In step 8 I don't know where to type the code in, which Dos command, the dos command window which nvflash step opened( and I didn't press enter to close that window), or I have to open a new one( or make a new .bat file with the code).
I do it and cann't see it install the original rom( "You will see it starts to installing the original rom..(about 3 minutes)..and then power off autmotically after finishing flashingtes" as you wrote in step 9)
So I still cann't fix my problem.
Please help me!
Thank you so much, you are a life saver.
yesterday, i can not do the step 8 because i can't run cwm to wipe all before, so nothing happen after i press enter.
but now, everything is ok.
Thank again!

Moving to Q&A
got it working now got an Os splash screen but it works this is how i did it
HOW TO RESTORE YOUR STREAK BACK TO FACTORY CONDITION:
Option 1.
1. Download the stock recovery ROM HERE (http://hotfile.com/dl/61659279/506ac...stock.img.html) and the stock official Dell ROM HERE (http://hotfile.com/dl/61663686/7d7e5...99_21.pkg.html).
2. Rename the stock official Dell ROM 'Update.pkg' and put it in the root directory on your SD card.
3. Boot Streak in fast boot mode (hold camera button when turning on), press 'Fast boot Mode' button, wait 10 seconds then connect to your PC (must have Dell PC suite installed).
4. Open a command prompt, navigate to the folder where your 'fast boot-windows.exe' is stored.
5. Type 'fastboot-windows.exe -i 0x413c flash recovery c:\recovery.stock.img' . Make sure the .img file is in c:\ directory. The program will now update the recovery image on your Streak.
6. Once the phone reads 'Recovery Done', remove the battery and insert it again.
7. Boot Streak in Recovery mode (hold down vol up and vol down when turning on) and select option 2.
5. Wait till it installs and it'll boot into Android....DONE!
Option 2
Place update.pkg on SD card root folder
Power up streak whilst holding both volume buttons
Select option 2 - "software upgrade via Update.pkg on SD card" by pressing camera button
Press camera button again Job done
i think later tonight i'll try to upgrade to 2.2 wish me luck and thanks for all your help EDRILL
i spend a whole night now to get android work on my hd2. had the same error message...
now i know why it didn't work and the solution was dead easy i had to beat myself...
sd card has to be FAT not FAT32
after formatting the card this way, everything works fine ^^
Are you sure it has to be FAT? I have heard there are restrictions on this format that would make it impracticle to use on a 16gb microsd.
Also how you format to fat? my computer only has 2 options to format: Fat32 and exfat.
FAT can only allocate up to 2 gigabytes of storage so there is something dodgy about that explanation.
I have a Viewsonic GTablet. I have used it very little and know nothing about rooting or ROM's or anything. I picked it up one day and turned it on and it's in a loop while booting...it goes from "viewsonic" to "Gtablet" to "TapNTap" then sticks there for several minutes then turns off. I have tried holding down the power and Vol. + and It comes in the upper left hand corner saying "Detect Recovery Key Pressed" and then "Booting recovery Kernal Image". Then the "unpacking box" appears...nothing happens but when I press the "HOME" button it says "Formatting MISC" and then "Rebooting" then the loop again. Called Tech support they laughed and said send it in...not sure about all that but would rather figure something out before doing that...thanks in advance...remember I am a NOVICE...so simple instructions please LOL

Did that it came up with the first 2 "Detect Recovery Key Pressed" and "Booting Recovery Kernal Image" then to the "upacking box" for about 5 seconds then to the loop again. Still lost...thanks for trying to help any more suggestions?
http://forum.xda-developers.com/showthread.php?t=1008245
Look for the links about installing clockworkmod. Once installed you'll need to try the data wipe and possibly repartition your internal storage. That will cause any data stored there to be lost.
tried all of them and the tablet will not recognize the SD card or being connected to the computer
A little more than tried all of them would be helpful...
Did you get CWM installed?
Were you able to wipe data?
Did you partition?
What was the result of each of those actions?
Is the tablet still looping?
Can you still get into recovery?
If not, what exactly is it doing when you turn it on?
No..I put that on the SD card and put the SD card in the tablet. Booted up and it goes through the same cycle. It will not even boot from the SD card. It never brings up a menu to cycle through with the Vol + or -....if I connect it through the USB it never recognizes it because it never comes out of the boot loop.
Thanks for all your help...I am really a novice with this thing
Well... It doesn't boot from the SD Card. Recovery looks at the SD Card to see if there is anything for it to do. Back to basics...
Install ClockworkMod: http://forum.xda-developers.com/showthread.php?t=865245
The first part of that post describes how to do it. Use the MicroSD card version which you will find at the bottom of the first post. You'll need to download it, extract it and put the recovery folder and update.zip at the root of your MicroSD card using your computer. Then put the MicroSD card in your tablet. Turn the tablet on while holding down the Volume Up key. You should boot into recovery and see the little box, arrow and progress bar. When it finishes you want to reboot it while holding down the Volume Up key again. That will get you into ClockworkMod (CWM).
From CWM main menu you can wipe data. Try that and see if it helps. If not then reboot while holding the Volume Up and go into CWM again. Select "Advanced" menu and you'll find the partitioning command. Select it and answer the two questions with 2048 and 0. This will erase everything stored on your tablet in the user storage space but should fix the problem.
Tried it
Tried it and this time it worked like......clockwork LOL...thanks so much...any more advice to have an awesome butt kicking machine?
Glad to hear it. Hang out around here for a bit and read up on the custom ROMs and stuff. You can turn these tablets into some pretty kick butt machines without too much effort. Just take your time and make sure you understand the process before you get started.
I'm new to Android, my first step was to research hardware and functionality. The choice, you guest it, gtab!
Now of to the good stuff. I ultimately want to root and update my Rom to vegan5.1. So far I have downloaded cwv08, upload downgrade and vegan. The problem is that when I try to restart using power + volume +, I do see the open box screen but then it just loads tnt and resumes boot. There has to be a step I must be missing here. Like I said I'm new to grab and android. Where do I start?
To my understanding, power with volume + without cwm install will run the command file in recovery folder. Preharps u are missing the file, preharps u are not naming the file correctly; too little details provided to tell..
try reading : http://forum.xda-developers.com/showthread.php?t=865245
same box with green arrow
I too have installed clockwork. Downgrade the bootloader then try to reboot into clockwork using the + and power. The tab acts like it is going to enter recovery says "Detect recover key press
Booting to recovery image"
Then it goes to that screen with he box with a green down arrow coming out of it and a progress bar. When it finishes it reboots. Still at stock rom, no joy at all.
A couple things I have tried. Copying a new update.zip to the root of the internal memory and the sd card, reboot with and without the sdcard inserted, rebooting normal then trying to get reboot recovery with + and power, copying the cwm update and recovery folder into root. No joy each time it it is the update box. I have not tried holding the recovery keys down in the dark while chanting xda but I think I missed my chance for that working last Friday.... when is the next Friday the 13th?
Thanks for any help or insight anyone can give us.
Bednab,I could not have explained any better. This is exactly what happens with mine. Today I encountered another challenge. My gtab will not connect to my-fy on open iphone. I have to figure this out before my road trip next month.
and there was much rejoicing
I kept at this and finally found a solution. A post pointed me to the answer on androidforums about the command file getting deleted out of the recovery folder after a successful update. I opened the recovery folter on the g tab and it was empty so I opened the one from cwm and edited it to this:
--update_package=SDCARD2:/update.zip
This way it points to my external card where I had a few custom roms. Copied it to the recovery folder in the root of the gtab, reboot into recovery mode and much joy!
Background info:
The G Tablet came with 1-1-3389 and I performed the OTA update to 1.1-3588 which went fine. I then rooted it with z4root and that went fine too.
1. I then side loaded ROM Manager and was able to install CWM Recovery and then was able to do a backup of my base ROM.
2. I then copied update-cm-7.0.3-Harmony-signed.zip and gapps-gb-20110307-signed.zip to the internal storage on my G Tablet.
3. In ROM Manager I chose to install ROM and I selected the gapps-gb-20110307-signed.zip and the tablet rebooted and came up in CWM Recovery. I watched it install 7.0.3 and then it rebooted on its own.
4. The tablet now will only come up to the Viewsonic screen with the birds on it and it just sits there.
5. I press the power button and hold it down to power off the tablet. I then press the + side on the volume rocker and press the power button. I get the "Recovery Key Detected" and then get a screen with a box on it with an arrow pointing down and a task bar underneath then it reboots and comes back up to the bird screen and just sits there.
I have read many threads about this but I am not sure just what my problem is exactly. The fact that I am unable to boot into recovery seems to be the biggest issue.
I have downloaded update-smb_a1002-3588-user.zip and update-smb_a1002-3389-user.zip and have went so far as to unzip the 3588 zip and copied its contents to my microSD card and inserted it and have booted it up while holding the + rocker down again...in another post on the subject I thought I should get "Recovery Image detected" due to the fact the microsd has the following on it...
data folder
META-INF folder
boot.img
bootloader.bin
recovery.img
system.img
Or did i totally misunderstand what I read?
Any ideas?
Maybe others can give a more specific answer, but:
If you're willing to completely reset your tablet, you can use nvFlash to get it back to factory condition.
Just Google:
nvFlash "g tablet" roebeet
And follows the steps that roebeet outlines to get your tablet up and running again. It looks rather complicated, because the instructions could be formatted more clearly, but in reality it's a pretty simple process.
Note that doing this WILL erase ANYTHING you have on there.
thanks for the reply....I do not mind losing anything to get it going again
I am back rocking again...thanks!
Ok, I know this has been posted before, but I can't find my specific problem and I've tried just about everything here and other web sites with no luck.
facts;
1. cannot load CWM any more (stuck at "booting recovery kernel image")
2. cannot load anything into internal memory. I can see a drive show up on my computer but it tells me to insert a disk.
3. APX usb driver works, ran nvflash (different versions) successfully but tablet does not reboot by it self afterwards. it hangs where it reads "Entering NvFlash recovery mode / Nv3p Server"
4. tried recovery through external sd card with no luck.
PLEASE HELP!!!! REALLY LIKE ANDROID AND DON'T WANT TO TRY IPAD.
Look in my signature. Code red.
thx goodintentions, but i just tried code red, double red, tripple red and detox. Everything seems to execute fine during nvflash. My computer starts running the bat file and my tablet displays "Entering NvFlash recovery mode / Nv3p Server"
computer finishes bat and reads to press enter, i press enter and window closes, but my tablet never leaves the black screen with the same message "Entering NvFlash recovery mode / Nv3p Server".
Even when i do DETOX my screen displays the red "magic value mismatch" message like it says in your steps, then i nvflash again and i'm back to square one. with 3 birds and no CWM. Any other suggestions?

According to rajeevvp, sometimes formating the MISC partition can fix the tablet not booting into recovery/CWM. I have had other users try this and it has worked for them. Save the attachment with a .bat extension, drop in your nvflash folder & execute it. Power down the gtab after running it and then try restarting in recovery mode.

Did you make sure to wipe data right after nvflash? Did you use the right nvflash file (the one with cwm pre-installed)?

Formatting the "misc" partition is useful only for some specific cases, and this doesn't seem to be one of those. Here, the problem seems to be that he's not able to boot into recovery mode which suggests a CWM problem, possibly due to a bootloader/kernel mismatch.
You should wipe the misc partition if:
1. Every reboot goes into recovery mode.
2. You get a message everytime from the bootloader saying:
Detect a recovery command
Erasing MSC

If your stock recovery to CWM recovery process was botched or aborted, then you should wipe the cache partition also.

Did you use the correct version of CWM for your bootloader? Try loading the latest CWM-4.0.1.5. Use the nvflash command as indicated in the thread with a "--go" tacked on at the end.

Did you go to "mounts and storage", then select "mount USB storage"? If you did, and the drive still appears unformatted, then you'll have to repartition the internal SD card. (There are other ways of fixing this problem without losing (too much) data, but it's fairly advanced involving some command line work in CWM.)

For nvflash to reboot the gtablet, the command line you use has to have a "--go" at the end. If you don't, then the bootloader will wait for additional commands. This is the normal behaviour. Did your command (actually, the final one if there were a sequence of nvflash command lines) have a "--go" at the end?
thanks everybody for your input.
rajeevvp , i downloaded CWM-4.0.1.5 but don't quite understand the instructions for execution. (sorry still a newbee).
also, if "mounts and storage" is in a menu of the actual tablet then i can't access it.
NOW THE NEW. in desperation I took it appart and unplugged the battery and tried discharging the caps. still nothing. THEN in even further desperation i shorted a couple of the battery wires wile tablet was ON trying to load the kernel and my tablet went into CWM... this was reproduceable and it loaded CWM every time BUT even thou i could get into CWM I could not actually execute anything from it because it would not detect me touching the HOME button to execute. sooo still stuck.

This makes me wonder now if you followed goodintentions's code red/.../detox steps correctly: If you've correctly completed any of the code ... procedures listed on the viewsonic g-tablet for dummies site before, then you should not have any trouble with the nvflash instructions for installing CWM-4.0.1.5. Put the tablet into APX mode (Power and Vol [-] key) and then just run the command as listed on your desktop PC.

From the frying pan into the fire now, I would say.
What was previously a fixable problem may now have become unfixable. The first order of business is to get the soft-keys working again. Check for loose and unattached cables. When the keys start working again, try installing just CWM after putting the gTab into APX mode. If you have a 1.1 bootloader:
Code:
C:\> [B].\nvflash --bl bootloader.bin --download 9 recovery-clockwork-4.0.1.5-smb_a1002_bl1.1.img --go[/B]
Get the bootloader.bin file from one of the zip files on goodintentions's web site. You can use any version of the bootloader.bin file as long as it is for the gTablet, but, for the "--go" parameter to reboot the tablet, the bootloader and the kernel installed should match (ie. 1.1 bootloader should have a 1.1 kernel). The bootloader.bin is just executed and not written permanently anywhere.
If CWM doesn't stick, then see this post.
thanks, i"ll be dedicating a couple of hours to this, wish me luck.
