Hey guys, so I rooted my gtab after I got it today (from woot), and went to flash CM7 (after rooting per http://forum.xda-developers.com/showthread.php?t=865245). On boot, it went to the ANDROID text screen, then went blank, and stayed there.
I then tried flashing g-harmony, as well as doing a full wipe. The same thing happened.
So I was getting a little weirded out. I then tried to do a full nvflash, using the G-tablet format then nvflash.
After the G-tablet format, there was some red text on the g-tab that said about some error with a magic file... not sure what that is.
I then booted up, and it got to the stock ROM, then it blue screened(?).
I did another nvflash, and this time after the g-tablet format, I got some red text about a critical error, but it booted up to the stock rom.
Now in the ROM, it shows no SD card, just 1.63GB internal memory...
I tried to root again, and it showed a triangle with a exclamation point in the middle. Now I cant mount the tablet to my PC at all..
What the heck is going on? How can I get it totally back to stock?

Put it in the box and send it back stating defect. I read your statement and there's were so many foreign things going on I couldn't keep up. Wow sounds like it's beyond something you did or could do. The question is do you want to continue on? The longer you keep something that could of or well may have been defective before your rooting experiment the better chance of you eating the cost. Your decision. I wish you the best for remedy.
did you try the repartitioning fix.
absolutely no idea if it will make any difference but at this point can't help.

Nvflash doesn't wipe the bct so user junk might still affect. Check the partition tool above or the gtablet format tool in development before that. But honestly I got a bad tablet too. It was so prone to bootlooping. Just exchange it.
So I tried the G-Tablet format again, and got the error for the "magic values" again. I have no clue what that means.
I tried to install CM7 again, and it boots to the ANDROID text, then the little android flys by the screen, then it goes blank... nothing.
Ugh.. calling viewsonic now.
So I searched for "magic number"

Magic Value Mismatch is likely caused by a corrupted zip download.
So when you flash that corrupted file it may complete succesfully but the end result isn't as good.
Sometimes even though the download may have comepleted it may still be corrupt.
What might help is downloading the zip file again from the source location and using that one instead of the original download.
Also, what may help (if you have access to recovery mode) is to flash
Calkulins Format all.zip file before you flash another rom.
This format all zip will wipe everything the standard Data & Cache wipe will not.
Thanks sleebus and tek, using the fix from that thread might help. But.. I ended up contacting Woot and they are going to do an exchange, no hassle. So Ill just get a fresh one.
When I get the new Gtab, ill re download everything and try rooting/ROM flashing again. Hopefully I won't have any problems with it!
Thanks guys, very helpful as always.

So i have used nvflash before and have ran into this issue before and eventually luck my way out of the problem but this time it aint happening. I am nv flashing the original nvflash_gtablet_2010110500 and it is successful but then it restarts and shows the gtable screen then when tapNtap shows up the screen starts to flash between the tapNtap logo and a black screen then eventually goes black. i flashed and reflashed 5-6 times and then tried the gtab 3588 apx and that didnt work and tried the first one and still no dice.
WHAT THE HELL!!!!
please someone help me .. i beg you!
After it goes black, have you tried holding down the "power" button to make sure it is off. Then restarting. Does anything happen.
Am I right that you are trying to get back to 2967 stock so you can do something else?

I figured it out and its really stupid. It was one line i didnt read. apperently NVflash DOES NOT format /data and well that was the issue. So i had to use NVflash and replace the recovery.img with the CWM.img and then boot into CWM, and wipe /data and then reflash 3588 via apx and it worked. stupid nv flash
You used nvlfash to fix a device. You didn't read the directions correctly and something went wrong. And you blame the program? Take a closer look at the user.
Agree with you, here people just jump to do advanced stuff to their tablets without reading and without knowing what the hell is a Rom and when things go wrong they blame any one besides themselves.
I nvflash my tablet, jumped from stock to vegan, tnt, and tnt 5 , flashing cwm, I don't remember how many times, and the only times I was in trouble was because I didn't read properly the warnings, but always I was able to fix it.
If you don't fully understand what you are doing, don't do it until you understand it.
My gtablet has been very happy and stable with the VEGAn-TAB GingerEdition STABLE RC1 rom for the last couple of months, but I've just run into a problem I can't get out of.
I was connected to my PC via USB about to copy some data off the tablet when everything froze. I needed to cycle power to get back to a workable system. Connected again via USB, and it froze again.
Next I booted into clockwork recovery and figured I'd have a look around to make sure everything was healthy with the filesystem. It wasn't. I was unable to mount the system partition.
At this point, I figured things were looking grim, so I opted to nvflash back to stock and maybe try again with the ROM. nvflash went ok, but after rebooting it bootloops at the white gtablet screen after 10-15 seconds or so.
Now when I try to go into recovery mode, it comes up to a black screen that reads "A N D R O I D", then i get an exclamation point, then it bootloops.
help! not sure how to proceed here.
thanks in advance for any pointers anyone can give me!
Code red (or maybe double red):
http://viewsonic-gtablet-for-dummies.webs.com/
I've gotten clockwork recovery reinstalled using this technique: http://forum.xda-developers.com/showthread.php?t=1058649
From there, I repartitioned the sdcard to 2048/0. It took a lot longer than I remembered it usually taking, but once that completed, I rebooted and got into the stock ROM without further issue.
Thanks for the space -- I've gotten rusty after having not run into any flashing difficulties for a while!
Double red it was! Thanks for that link bmag666. Definitely going in my perma-bookmarks.
Well I was caught my the new MIUI ROM i saw this morning and decided to switch from Bionix. I have flashed many phones and farmiliar with the process. I left my phone alone while the install occured. I watched it wipe data and cache. Now when it powers up, the samsung logo appears for 2 seconds and a quick I9000 logo flashes for like .25 of a second. The 3 button method to force it into recovery. I dont have a usable copy of windows to boot camp from my mac so ODIN is currently not an option.
I can get the phone into download mode so i know its not a lost sailor, i just need a mac solution without booting windows. I really dont want a refurb replacement from warranty either
You want heimdall.

SO here goes...
first off i am rooted, have all appropriate drivers, etc, have used dab to root.
I am a total newb, and was experiencing issues flashing a new ROM. when trying to install the zip through cwm the phone said "signature verification failed" or something to that extent. so being the deductive thinker that I am, I formatted everything: boot, system, sd, etc. After doing this, I realized that I totally wiped out all the files on the internal sd.
so i downloaded the heimdall one click- it connects but fails regardless of whether i flash boot loader.
i can access blue 3e recovery and download mode.
now. i want to know if it is possible to push or even install a ROM through adb. I've been playing around with it all day and have gotten nowhere.
i thought maybe i could load up a rom to an external sd but obviously you can't mount an extsd in cwm.
am i screwed?
ill gladly donate through paypal if someone can help me get my baby up and running again. i do not want to be using my nokia from middle school anymore!!
thank you in advance for ANY help you can give me.

I was attempting to flash the new Glorious Overdose rom onto my phone, and when I hit reboot, it won't leave the boot screen. It is perpetually on the boot screen. I worried because I didn't think I could get ODIN to work, but then I used AyoTeddy's fool proof method to get it into download mode. Now, from there, I attempted to use ODIN, but, it failed over and over. Pic is attached.
Is there anything I can do from here? I'm not confident about doing the soldering for that unbrickable mod, but I really like my phone and generally the contents, so....?
Now, when I was flashing, I thought I did everything right. I cleared cache, cleared data, then cleared dalvik. After that, I made sure that the system was unmount/mount (I was using the red CWM, although I recall in the past that my phone had the orange one?), and then I proceeded to flash .zip file.
Please help. :'C
ehhhh
I just bought a new one, but I'd still like to avoid the previous pitfall with the new one (since I don't know what I did wrong?), so if anyone has any advice, I'm all ears.
Thank you.
Hey Everyone. First of all I would like to say that I've had this device for about a year and a half, but it bricked? on me in only 4 months. I've tried countless methods to fix it but no go. Then as time went on I completely forgot about it. Now I don't have my sd card that I used for it any more.
The problem? One day I accidentally forgot to charge my tablet and it died on me, so I charged it right back up and turned it on. Everything went well, I got through the logo screen and everything, but then it just hangs there right before I hit the Home screen where you can do your code and everything.
Methods I've attempted:
I've tried going through CWM recovery to fix the issue but then I notice that it says near the bottom as it loads "E: Can't open/cache/recovery/log" and it has the same "E: Can't open/..." for everything. Can't mount, wipe cache, wipe data, restore, I have no backup (stupid right), can't do anything. Also, when I do attempt to wipe data through CWM I notice "E:Can't mount /dev/block/mmcblk0" if that has any special meaning.
I've tried flashing stock firmware through odin multiple times on different usb ports and different computers.
I've tried flashing PIT file (I'm not really sure if thats how you're supposed to do it but yea, I flashed the PIT file through odin by itself and with stock firmware)
Misc. Info: I did have a custom ROM installed(can't really remember which one), I also have the app2sd installed, the only thing that struck out to me when my tablet went out is that it received an OTA update for 4.1.2? and for some reason it went through even though I never intended to update.
I'm really, REALLY, open to any suggestion that could possibly help fix this tablet. On the other hand if the cold hard truth is that its gone forever or that I simply just have to take it back to Samsung (which I highly doubt I'll be able to), then please by all means let me know.
THANK YOU!!!
Bump
Help Please
Did you try flashing a different recovery again. CWM? Also after installing stock through odin try a factory wipe. It would probably help to know what your last rom was.
