I received my G Tab from woot on Friday. Yesterday I went through the process to install VEGAn Gingerbread. NVFlash, CWM, and then the ROM.
All was great until today when I decided to add an external card. The only micro SD I had laying around was a 2GB I used in an old phone. Used windows to format it to FAT32 and then inserted it properly into my G Tab. It wasn't mounting so I removed it formatted it again with Windows and then the G Tab mounted it. Hooked up the USB cable to move over some files and after going though the USB screens the G Tab locked up. All you could see was the spinning wheel. Windows wasn't detecting anything either. I left it for 10 minutes with no change and turned off the G Tab.
I removed the micro SD card and turned the G Tab back on. No joy, The Gingerbread screen was in an infinite loop. Decided to flash back to stock and try again.
After booting into APX mode (BTW, what does APX stand for?) and ran NVFlash, everything appeared to load properly. When the G Tab restarted it was stuck in an infinite reboot loop. First the Viewsonic screen than the GTablet screen and then reboot. I used NVFlash again with the same results.
The G Tab was very nice for about 24 hours.
Any help or suggestions are greatly appreciated. BTW, I am not a programmer but I try to carefully follow directions.
jerirat,
When I see boot loops, I think partition -- you need to repartition the tablet.
To do that you will need to install CWM. You can try and see if you can load
from a microSD card, or you can look at the sticky at the start of the General Forum
and load with nvflash.
When you get CWM loaded, go to the Advanced Menu and Partition (2048 and 0),
Fix Permissions and Wipe Dalvic Cache. Re-partition takes a few minutes.
Then go back to the Main Menu and Wipe Cache and Wipe/Reset Factory Data.
Reboot and see if things are working. If not, shut down and nvflash down to the
bekit 1105 (Version 2638). Then you can OTA up to 3588 or if you want D/L the
.zip version and install it. Getting to 3588 you can go and do what you want.

I was in a similar situation. Repartitions in CWR as butchconner suggested and it should fix your problem. It did for me.
Had the same thing happen to me only when I tried to repartition, something went wrong and it would not complete. If this happes to you, there is a utility called "format" that is used with NVflash. Do a search on the forums and you will find it. I'd use it only as a last resort as it completely removes everything from the gtab. Then just do a normal nvflash and it should allow you to repartition. Good luck!
So far so good, had to move the bootloader.bin up one directory level for the batch file to work. Repartitioning the SD card right now...
Wiped/reset everything you pointed out and I'm now rebooting. Looks like the stock ROM is loading.... and it's loaded.
Thanks! I'll have to reload the Gingerbread ROM but at least I'm not borked anymore. (I should have my wifi pw memorized by now since I've entered it sooo many times in the last day or so. )

I got my viewsonic g tablet yesterday and quickly installed tnt lite 4.20 and then tried to upgrade it to 4.25 but this time the tablet had an issue. When I rebooted, it kept looping to the reboot screen :-/. I didnt back up my software on the tablet. I downloaded the recovery folder and the update folder on my micro sd card so that I can downgrade my device but when I press power and volume up the device will not give me a boot from the micro sd card option. Some one PLEASE HELP!!!!
I've been traveling a few days and the Forums have changed while I have been gone, but there is a sticky in the General Forum that I used to explain the
recovery options.
If you don't find it post again and maybe tonight I will have time to write it out again.

about halfway down, there are recovery instructions. You need to change a line to SDCARD2 in the loader file.
I wouldn't try and reinstall the update though - might be best to re-run the full installer.
Long story short I find myself in a boot loop and am a little hesitant to try what I believe to be the 'next step' to recovery in case I am mistaken and totally fubar my new toy. (this is my first android device and I'd prefer not to brick it in the first 24hrs!)
As to how I got myself into this situation here's a play by play.
1) Researched internet for best value tablet with awesome dev community. Found my gtablet and xda! (buy, buy, buy!)
2) I spend the week leading up to taking delivery of my new tablet reading everything I can get my hands on.
3) Unpacked new tablet and played with stock rom briefly before saying farwell.
4) Installed clockworkmod .08 and then TNT Lite 4.4 and everything worked wonderfully
(youtube.com/watch?v=mY_FvJnWNEw&feature=related) used this method
5) when I turned my gtab on for round 2 I find myself in a boot loop, I figured there's an issue with something I changed so since clockwork seems to be working brilliantly and the update.zip file in root is the same I wipe data/factory reset and wipe cache partition and then rerun the update. This still leaves me in a boot loop...
6) In further reading the recommended fix seems to be repartition sdcard and then reinstall rom with clockworkmod off of sdcard2. I put the update.zip file with \Recovery\command (edited to point to sdcard2) onto the microsd popped the micro sd into the tablet and restarted... the tablet did not read the microsd when i started up clockworkmod. And so I am left with questions at this point and a semi-bricked device.
am I correct in trying to repartition the sdcard as my next step?
does the mircosd need to be of a certain format?
have I done something ridiculously obviously wrong??
Thanks in advance for your any help or guidance you can provide...
I'm experiencing the same thing man. However, i have another g-tablet that i haven[t cracked open yet and i'm wondering if i can just partition and copy/paste the folders from the g-tablet that hasn't been opened to get the device back to stock.
Hello!
I have just recently (last night) successfully recovered from your *exact* same problem. Short answer...Yes, Install CWM on your micro card, partition the sd card (2048 and 0). I have my microsd card formatted to FAT32.
Here is my thread:
http://forum.xda-developers.com/showthread.php?t=1028118
I specifically used "butchconner"'s first post although all of the responses were friendly and helpful!
Best of luck!

Wait a minute everyone!!!! (Talking about gilpin)
He said when he tried to boot the microSD card, he couldn't find it in CWM.
If CWM is up, that's the main thing he needs??!!!
If you can get into CWM, go to the Advanced Menu and run the Partition, Fix Permissions and Wipe Dalvik Cache options. Then go to the Main Menu and run
the Wipe Cache and Wipe/Reset Factory Settings.
Then re-boot and see if your tablet is okay.
If it's not (and CWM is still working), you can put the appropriate ROM update.zip
in /sdcard and then select and load it through CWM.
Hope this helps.

geedup,
If you are boot looping also, you need to re-partition and the nvflash back to
stock.
The following thread pretty well covers nvflashing:
http://forum.xda-developers.com/showthread.php?t=861950
After you nvflash, check to see if you still are getting boot loops.
If so, you need to load CWM and do the same thing as gilpin. When
you finish the CWM routine either it will be working -- or you can
nvflash again and it should be good to go.
Let me know......

working again...
Thanks for the fast replies all! I repartitioned my sdcard (2048, 0) reset permissions, cleared data and then rebooted. This seems to have fixed my problem as I booted cleanly and everything is working again!
First let me say that I installed CWM once already so I am fairly confident that I understand the basic steps. However, after I had initially installed CWM I tried to install a new ROM, but my tablet just hung on the "Viewsonic Birds" screen for like 45 mins. So, I shut down and booted to CWM but now my tablet is empty. I mean literally empty because I wiped everything in order to install the new ROM and somehow I messed that up big time because even that .zip file is no longer there. After some searching through the forums, I found a stock image of TnT 3588 and got it loaded, but in doing so lost CWM. So, I reinstalled CWM and saw it load (saw the cardboard box etc.), rebooted holding down Vol + key and saw the 'recovery key detected'. Then it goes to a screen with a progress bar and then it just boots normally....
Any help would be appreciated. Thanks!
I'm having the same issue after a nvflash that didn't take. Can't get into recovery.
I've had a few issues with that also. I try the SD card installer, drop it on the card named update.zip, reboot, it looks like it installs, but after rebooting it won't let me boot to CWM. So, I try the internal installer, drop it on the SD card named udpate.zip, it installs, I reboot, and go right into CWM. So either when I connect my tablet it somehow doesn't mount the SD card but mounts one of the internal partitions, or the SD and Internal installers were mixed up...
Hi everyone,
In my overzealous attempts to reformat an old 4gb external SD card through CW Recovery, I managed to reformat my internal SD card (I was using the Clockwork Recovery version 2.5). I thought that "format sd card" would reformat my external memory card and not leave me without a usable phone, but I guess I misunderstood.
I spent at least five hours going through all of the ODIN tutorials and trying them out, and found that using Eugene's 2.2 with 2E recovery ROM actually allows me to boot up (hooray! ), while the stock rom from this thread simply forces a bootloop on my poor phone, with occasional freezes. Even using AIO's "Flash to Stock" from Eugene's 2.2 doesn't work.
Further searching has lead to the thread about partitioning using parted, which has been hard for me to use effectively (I made a new partition, but I couldn't get it to mount properly).
I was really excited to come across this tutorial, but it didn't solve my problem. After getting through all of the steps, at step 5, ODIN3 versions 1.0, 1.7, and 1.81 (I tried all 3 on 3 different walk-throughs of the tutorial) never were actually capable of repartitioning the sdcard properly. Every time after the first time of using "parted" to reduce the card to a single partition, I found that that lone partition was always the only one there (15.5 gb /SYSTEM Fat32). No changes had been made to the sd card's partitions.
I don't know if it helps any, but the ROM I was running before I reformatted the card was Bi-Winning 3.0, and Voodoo had not been disabled at the time of the reformat, which may be why I can't flash new ROMs through the recovery as well.
As near as I can tell, ODIN can't actually return my vibrant's partitions to factory settings, so is there a way for me to do that manually? I think that would solve my problem.
Thanks,
-NewbieCube
My guide (you linked to) clearly states its not for this intent... if you read it, you would also see I linked to Eugenes froyo that does not brick. If you did it, THEN you did my guide ODIN to JFD, you are on a fully functional stock 2.1 JFD build.
If your intent was to just format the external sd, go to menu settings, sd card/phone storage, unmount the external and format it.
Right, I know that. In fact I read all through your thread and tried to flash to Eugene's first, and then to JFD, but JFD does not boot properly. It just gives me a black, unresponsive screen. I'll definitely go back through once more and try that again, though, as you clearly know what you're talking about.
I basically formatted the wrong storage (internal sd vs external sd), and would like to get that internal back to stock, so you are right that Eugenes -> JFD should work. I'll report back with results.
^ yeah, exactly... that should work with no issues. let me know if it does not.
Oddly enough, that didn't work for me either. Since my phone still can boot into Eugene's (albeit with 0.00B available to apps), I know this should work, just from reading through your guide. So once more, here's what I did:
1. Download mode -> ODIN 1.70: Flash Eugene_2E_JK2_Froyo.tar.md5, and s1_odin_20100512.pit (from Eugene) Re-Partition NOT checked (Eugene's thread says not to)
2. Boot up into Unbrickable Froyo, with no application space remaining Mount sdcard and move Update.zip (s15274n's) into the root folder without issue.
3. Download mode -> ODIN 1.70: Flash s1_odin_20100512.pit, and T959UVJFD.tar (s15274n's) with Re-Partition checked
4. Boots once automatically into recovery, saying something about a failed MBR checksum and failure to clear userdata
5. Bootloops that never get past the VIBRANT logo screen
6. Boot into recovery and try deleting user data and cache data manually and to reinstall packages, but bootloops continue.
I really don't know what I'm doing wrong here...
UPDATE:
I even used Heimdall on another computer and got the same result, so it isn't ODIN. Why is reformatting the internal SD card to stock so difficult to do?

I FIGURED IT OUT!!! ...by random chance
For my problem, it was indeed the voodoo lagfix that was messing things up, and this post:
http://forum.xda-developers.com/showthread.php?t=888084
helped me out tremendously.
So, I recently came in contact with an old Nook Tablet 8G and decided I would turn it into a fully-functional tablet. Every went swimmingly, installed recovery, obtained root, and managed to get CM7 running. No major problems thus far. But, since I had been working in my 8 gig Micro sd for my phone, I decided to remove it and recreate it on a small sd. Well, I must have not been firing at all cylinders, because I formatted the old sd before making a new one. So far I have been able to run CWM 5.5.0.4 off of a SD but the /cache/ partition is inoperable. I have attempted the several "Boot and nuke" -esque techniques of factory resetting with varying results. For the potential fix detailed in this post, I receive the "Do not turn off device" screen, but briefly after I am greeted with a "Device is restarting in 5 seconds" "Make sure to take out the sd card" After this reboot, I am plunged back into the same recovery. I'll try and get a video in case I am being too vague.
Fortunately, this is an old nook, so no one is going to miss it for a bit... or ever potentially. Thanks for reading this.
