NVFLASH SUCKS!! Please help!

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.

Bricked GTab? Ive tried everything. Help

I have been searching everywhere the last 48 hours trying to find someone with the same problem as me...
I did a full NVFlash, because I was going to install Honeycomb. While the Honeycomb ROM was installing, my GTab must have like slipped off my desk a little. Anyway, the power button ended up being pushed down, and the tablet shut off in the middle of updating the ROM.
Now, it will not power down, not even to the viewsonic logo. The screen just stays black. I can tell it can go in APX mode because of the little noises XP makes when something is plugged in.
NVFlash does not work. When NVFlash is 'done' the GTab screen reads "Entering NVFlash recovery mode / Nv30 Server". And the NVFlash Command prompt says it failed.
I have also tried draining the battery, and also opening the back, unplugging the battery and hitting the reset button. Nothing has worked.
I would really like this thing to work again. Any ideas are greatly appreciated.

just restart your computer. Then put the tablet back into APX mode by listening to the "sound" in xp. NVFLASH does not delete the APX partition data so it should still be there. Other than that it seems like you're doing everything right.

Thanks for the quick reply,
Unfortunately, it did not work..
I went through NVFlash again, at the end it says:
read failed NVError 30001
command failure:create failed
press enter to continue:
Then it closes.
Any other ideas?

hmm, I guess I would try redownloading NVFLASH. If you are attempting to flash a 1.1 kernel try switching it to a 1.2 kernel. If that flashes successfully attempt a 1.1 again. It should be working since you can get into APX mode.

Thank you, so much! I actually never knew there was a 1.1 and 1.2. I originally followed directions for 1.2 only.
Again, thanks!

Have you tried hammering your gtab? Have you tried banging your head against the wall? If no, then obviously you haven't tried everything.

[Q] 3.2 Update Problems, trying to understand APX

I had rooted/cwm'd my tf101 when I first got it. It was running the 3.1 update at the time. I followed the pure root posts here on XDA.
Sadly I had never tested CWM, and perhaps since it went so easily I didn't really understand/read enough on CWM to understand what is happening. When I ran the 3.2 OTA (OK so I shouldn't have done that, I know now) the TF froze on the initial splash screen.
I've tried many things and read tons of posts here on XDA and other sites, and I'm not getting anywhere, but part of it is I don't know for sure what I'm trouble shooting.
I was using a dual boot laptop in Windows mode when I did the initial update. I had the drivers working and succesfully rooted my system.
What I am trying to do is restore a stock rom for now and I've tried several methods.
1) Asus download SOP - It detects the image on the SD card, checks validity of the firmware, shuts down and reboots and hangs at the first splash screen.
2) CWM recovery, if I understand this right, I Power+ vol_down. I hit the vol_up to enter The screen says
Checking for RCK. press key <Vol_Up> in 5 sec to enter RCK.
I do that and it hangs at:
Booting recovery kernel image
3) I've tried several nvflash posts out there. NVFlash does not seem to be working, I've now done this on two windows boxes. Both the one that used to work, and a clean windows XP machine I had lying around. In both cases, I can get the nvidia APX drivers loaded and the device is seen. However, adb doesn't show any devices, and from pulling apart the batch files and doing some reading, I tried nvflash -r --getpartitiontable myfile.txt and some other commands which always hang. Eventually if I disconnect the tablet - then I get a read error of some sort.
4) quick reboot - every option leads to reboot and freeze at first splash screen.
So questions that I can't seem to find an answer too.
1) If I'm connected in APX mode, should adb show a device? Like I said the PC recognizes it as the APX device and loads the nvidia drivers instead of the normal transformer MTP drivers when I do the power + vol_up.
2) Is there a simple test to use for nvflash? The device shows up, is there anyway I can confirm whether APX mode is working or not?
I'm only starting to piece together the boot process in my own head, and my guess is that niether the stock recovery image or the cwm recovery boot image is working. Would that be a reasonable assumption based on behavior? I will admit I really don't understand the boot loading process in android.
FYI, if I go through Power+Vol_down, wait for rck to skip and then boot without wiping, the TF is fine after that. Meaning as long as I don't try to update, it will work and reboot normally. Root also still seems to be working.
I tend not to suspect a driver issue, since one machine was confirmed working, it's how I got root - and 90% of the time that machine is run as linux. I almost never boot into windows. I'm pretty sure the last time I did was to root the TF.

What happened is you overwrote the cwm when you installed the new update. You can't just randomly install things once you're rooted.
If you have a B7O machine, you need to check that you have the old or new sbk. Go to the general transformer forum, and there's a thread about the new sbk locked bootloader. Follow the test to see if you have one that you can use nvflash with. If that is the case, then go to the dev forum, and look through the nvflash unbricking thread.

Thanks for the reply
First off, you're right and I should have known better. Almost nothing I own runs it's stock firmware, and I just got dumb and didn't do the full research excited for HC 3.2 goodness.
I have a B50 machine, or at least the my serial number indicates that.
I've already tried several nvflash debricking instructions, but it seems that nvflash is not working either. I have several copies of prime and the .11 release from asus. But since nvflash is not behaving as expected, all of those threads are not helping.
I do have the nvidia USB recovery device show up in device manager, but every nvflash command fails hangs at
nvflash started
[resume mode]
ADB devices shows a serial when I'm normally connected, but it doesn't show up when I'm in APX mode. I'm just not sure if the device is in a functional APX mode, since nothing actually runs, despite it showing up in device manager. I've tried googling that situation, but I can only find posts that tell me how to get it to show up in dev manager... It seems like when that happens everyone else has been fine.
WHILE GOOGLING FOR MORE INFO ON b70 - I managed to get NVFLASH working, and now I get what the first command and -r do.

3.2 Update Problem SOLVED
So look at the original post for the strange condition I had gotten into.
Somewhere along the line, the transformer had stopped responding to adb even not in APX mode.
I uninstalled PC Suite and Asus Sync. Then reinstalled only ASUS sync. ADB started working when TF was connected normally
I did not reboot my PC, win7 64 bit. Shutdown transformer, it hung at the splash screen. WHILE HUNG, I held power and vol_up until device manager showed nvidia USB recovery device
I used the stock rom replacement from tabletroms. Sorry I can't include the link as I am too new to XDA.
Got the transformer back up, set up my account, restored data. However OTA from there was not working.
So I went to ASUS, grabbed the .11 image and updates via SDCARD following the SOP instructions.
After reboot, checked for updates, and there was one. Let it do the OTA for 3.2 and now I'm back at having stock 3.2 updated TF.
I will probably root, but may not CMW this time.

Stuck in APX mode

First time rooting the tablet. Thoroughly read and understood all instructions and have had multiple android phone devices that I have rooted/soft bricked/unbricked/restored to original so ive been through the process.
adb working and got tablet into apx. performed every step in the pure root for tablets thread and everything went well.
ran root.bat, tablet says it updated successfully
ran cwm.bat for clockwork and it shows to update successfully
instructions say to restart tablet, done. Now it stays in apx mode and will not go into booting screen.
tried to use nvflash to restore since i have apx access. run it and it appears to complete on the computer but on the tablet it only shows that i got into nvflash recovery and the chip uid. It never shows if it is successful.
Is there anything else I can do from while in APX? restarting the tab immediately dumps me back into apx even if i dont hold the up button.
Thanks for the help

Did you try holding the power button down for 10-20 seconds?
If you are using the pure root method, you can use nvflash --resume --go to kick start the bootloader. You might have to add ./ or \ and .exe.

I managed to fix it after looking over everything.
the recovery nvflash would exit faster than i could read if there were any errors so i changed the batch file to incorporate /k
(edit your batch file and before the 'nvflash.exe' command put in 'cmd /k' include the space and add a space after the /k. Save it and let it run and it wont close after it does whatever its doing so you can now see what the prompt is doing)
after that I saw that nvflash failed bc it didnt have the boot/system/recovery images in the folder.
i cant post external links and cant link to the img's i got but just do a quick search for nvflash and prime you'll find em.
I knew it was prime and wanted to keep stock but with root but whatever, I'll look to get back into stock later.
just posting this up so if someone has the same problem they can fix it.

You MUST use apx to restore your device it seems the boot partition is wrong you should restore that with nvflash.

HELP! I Brick the Tab.

Hi, im from Argentina.
My problem is the next.
I was trying to flash the new Flashback Rom 10.3.
Mi Clockworkmod was old, (cause i didnt have many options like the advance features). So i tried to update the recovery using ROM MANAGER from the market.
I use the first option (install clockworkmod) and then the fist item (dont remember wich, the name was like Elysium or so).
Then the tab restar and didn power up again.
My pc cant recognise the device by any form. Its not in APX mod cause of it
C:\Users\PC\Desktop\Gadgets\Gtablet\Nvflash>"nvflash.exe" --bct gtablet.bct --se
tbct --bl bootloader.bin --configfile gtablet.cfg --create --go
Nvflash started
USB device not foundPress enter to continue:
Please any help of the advanced users. Thanks so much.

Problem solved. Had to Open te Gtab and use the Hard Reset button on the back.
My problem now is the CWM. I try to re install it. Put the update.zip and the recovery folder (copy and paste above the cracked recovery from Rom Manager).
When i try to Boot into recovery it freezes on Loading kernel Image.
What can i do now?

If you can get your tablet into APX mode for NVflashing you need to get the latest pack to update your CWM and stock rom to a 1.2 bootloader in order to update to Flashback.
http://forum.xda-developers.com/showthread.php?t=1118898
This will help guide you into switching from 1.1 to 1.2 bootloaders.

.....and for God's sake, whatEVER you do with any other Android device, DON'T use Rom Manager on the GTab. You'll soft brick it 9 out of 10 times you use it. It's a fairly well documented issue with this device. just my 2 cents....

I would have to agree that if you are now able to get into APX mode, the best thing you can do is to NVFlash back to a stock 1.1 or 1.2 bootloader (see the previously mentioned thread) and start over from the beginning. Know which ROM you intend to use before you choose an NVFlash path, so that you flash to the proper bootloader version for the ROM you want to use.

Help, Gtab won't boot
My G-tab will not boot. It will only go to the APX mode. I have been reading this site for the past three days and have tried everything that I can find but nothing works. I can load CW and complete all of the steps, I can even get the gtab to boot up when I nvflash it but as soon as I reboot the gtab it goes into the APX mode. I would appreciate any help with this.

Take a look at gtabletfordummies website. Start with code RED if you haven't already done exactly those steps. Use the NvFlash file from their site for your bootloader version with CWM already installed. If you have to use code DETOX and have problems after, you may need to search XDA again for "magic value mismatch error". (Sorry I can't post links so you will have to search!) Make sure you read everything and don't skip any steps.

Thanks for the reply but I have already went through all of the different sections of Gtablet for Dummies and my gtablet will still not boot past the APX mode.

Only other thing I can think of to try would be to remove the back cover of your tablet and hold (10 - 15 seconds) the internal reset button on the back of the board. That should factory reset it. Search this site (xda) for "gtablet hardware breakdown" for pictures and some info about taking it apart.
