I had installed TNT Lite v 4.3.0 a couple of weeks ago and it was working pretty good. But today my tablet has gone into a bad state. Every app that I run results in FC. Even the ADW launcher EX that I had selected default is crashing. It then gives me the options: ADW Laucher, ADW Launcher EX, and the regular Launcher. The plain ADW Launcher also fails, but fortunately the regular Launcher still works so I can access the apps.
But unfortunately almost every app that I am trying fails. The only one that doesn't fail is the Web browser. The Settings starts and I can access Applications menu but once I choose say System Applications, after that if I try to choose some other option such as Installed Application, it crashes as well.
Last night however when I started the tablet the battery was probably down and while it was powering it up, it turned off and then restarted by itself and then turned off, without reaching the lock screen. I don't know if it has something to do with all this.
What do I do now? Any help will be appreciated.
Thanks.
A well known issue.

This is why I'm an advocate of people doing the partitioning right before they flash their first custom rom. This way, they won't have to wipe everything later on.
I could only wonder why people aren't mentioning this in every custom rom thread.
Thank you so much. Will try it out tonight.
Unfortunately it seems I have run into a worse issue (without even doing anything yet). Now when I power it on, it starts and shuts off within a few seconds, just shows the birds for like 5 secs and bang, black screen.
The tablet is fully charged (if I put it on charge the light turns green in no time). Looks like the battery is dead.
You might be dropping into APX mode. Do you know how to use nvflash?
Thanks for the reply. You are absolutely right. After multiple tries it did boot up and I was able to install clockworkmod and it all worked great. It wiped off everything but I could live with that. And I turned it off and back on and it was working fine.
But then it went back into the same mode - shutting off immediately after turning on. I decided to return this tablet thinking that it is bad. But before I would do that I thought to restore it or else Viewsonic won't honor the warranty. So I started reading the thread about restoring the tablet to stock using nvram flash. In that procedure it requires me to put the tablet in APX mode and that's when I thought that maybe it is going into APX without pressing the volume - button.
Anyway I was successfully able to flash nvram. Or so it said. I still have the output from the batch file. But now my tablet is totally bricked. It does not boot at all. No pretty birds for me.
I hope there is some way out of it. Please help.
Edit: After re-flashing and using a different file, it seems to have made it a little better. At least I am seeing the birds again. But the original problem of shutting off, or going into the APX mode without pressing Volume button, has returned. All I am getting is the birds for a few seconds and then black screen. I will continue to retry, and if I see it booting up successfully to the stock, this thing is going back to the factory.
1) What image did you use to nvflash?
2) What happened when the flash was finished? Did it boot normally at least once?
3) Does the screen just stay dark all the time now?
1) First time nvflash_gtablet_46_2010112600.zip and after that it did not boot at all. Only black screen. I flashed it couple of times, no avail. Later I flashed nvflash_gtablet_2010110500.zip. This at least recovered it enough that it shows the birds, but soon after the screen turns black. I have confirmed that it is going in APX mode. If I have USB cable connected to my PC, the PC reports discovering the NVIDEA APX device.
2) It hasn't booted normally since I flashed nvram.
3) No I get the birds, but after that it turns dark.
Ok. Using Bekit's 1105 image...
1) Replace part9.img with the recovery.img out of the clockworkmod installation zip.
2) Put the tablet into APX mode.
3) Type in the command to start nvflash but before you hit the enter key hold down the Volume Up key and continue to hold it down until the flash finishes.
4) The tablet should boot into clockworkmod recovery.
5) Repartition 2048 and 0
6) Clear everything (cache, data and dalvik)
7) You might need to re-nvflash at this point.
Thanks for your response. I tried it. Did not work. When you say Replace part9.img with the recovery.img, does it mean copy recovery.img into the NVFlash directory and rename it to part9.img or leave it as recevery.img. I renamed it to part9.img and backed up the original part9.img to part9.img.tmp. The size of recovery.img and the original part9.img are very different. I am confused. Please help.

Yes, that is exactly what I meant.
Are you sure you're holding the volume UP key? Birds and then black screen is APX mode which is normally entered by holding volume DOWN.
Well it goes into APX mode even if I don't press any Volume button at all. That is the problem I am trying to fix. When I press power button (without touching the volume button) the birds come and then black screen. And this is APX mode because if I am connected to the PC it brings up an NVIDIA APX device on the PC.
Now if I press the Volume UP button along with the power button, nothing happens, not even the birds come up.
So the fact that the recovery.img (3.7k) is much smaller than part9.img (16k) is ok? Or I am doing something wrong.
Any ideas?
I was thinking about formatting the gtablet. Please let me know if this is the right move, or there is something else I could try first.

A little more than "It did not work" would be helpful.
What step failed? Please tell me what happened after each step.
Did you get into CWM and repartition?
Did you get everything cleared?
What happened when it rebooted?
What was the original filename of the image you tried to flash?
What version of clockworkmod do you have installed?
Have you ever used ROM Manager?
All of this is important and no one can help you if you don't provide enough information.
Oh, I am sorry. Here are the answers to the questions you asked:
What step failed? Please tell me what happened after each step.
Ans: Out of the 7 steps you provided, the steps 1, 2 and 3 worked fine. It is the step 4 that failed (and of course I can't proceed with the steps anymore). In other words I cannot go into clockworkmod recovery.
Did you get into CWM and repartition?
Ans: No I was not able to do so. If I press power and Volume Up key at the same time, nothing happens, screen remains black, not even birds come up.
Did you get everything cleared?
Ans: I believe you are referring to step 6. No, I could not get to that step.
What happened when it rebooted?
Ans: Nothing showed up. Because when Volume Up is pressed while it is powered on, nothing shows up on the screen.
What was the original filename of the image you tried to flash?
Ans: Actually first time nvflash_gtablet_46_2010112600.zip (and this is before you provided the 7-step recipe - see post #6, 7, 8 of this thread) and after that it did not boot at all. Only black screen. I flashed it couple of times, no avail. Maybe that was my mistake. I chose a wrong file. Later I flashed nvflash_gtablet_2010110500.zip. This recovered it enough that it shows the birds now, but soon after the screen turns black (goes into APX mode).
What version of clockworkmod do you have installed?
Ans: v08
Have you ever used ROM Manager?
Ans: No. What is it?
I really appreciate your help.
What happened at the end of step 3?
Did you start holding the volume UP before you pressed the return key for the nvflash? If not... go back and do it again.
Did you continue to hold it until the flash was happening? You must continue to hold it down for at least 5 - 10 seconds after the flash starts.
When the flash was done did it say "Recovery Key detected" on the screen? If it didn't say this that is an indication that you didn't hold the volume UP key long enough.
If all of the above was done correctly and did happen but you didn't get to clockworkmod then what did you get? Did it look like stock recovery?
It sounds to me like you did the nvflash then tried to reboot into recovery.
Its unbelievable. Tonight when I powered it on it started booting up normal instead of going into the APX mode. I was glad. The stock UI came up, but some of my apps like Quadrant, File Expert etc were still there. It also notified me of the Update 3588. So I downloaded it and started installing it. Pretty soon it rebooted itself (sooner than I thought - I don't know if the remaining installation was supposed to happen after the reboot).
But instead of booting up into 3588 it is unfortunately gone back to the same old issue - the birds followed by black screen - aka APX mode. It never booted up after that. No matter how many times I tried to reboot, it goes into APX mode just like before. I don't know what caused it to complete bootup. One thing I noticed was that the battery was totally drained when I started tonight. I don't know if the drained battery somehow took it out of the APX mode. But now it has a little bit of charge because of hooking up to power supply. I have disconnected the power supply and will leave it in APX mode over night and try it again tomorrow when the battery would be totally drained and see if it boots up fully.
To answer your questions though:
What happened at the end of step 3?
The screen went black and after that it stayed black. No CWM.
Did you start holding the volume UP before you pressed the return key for the nvflash? If not... go back and do it again.
Yes, I did.
Did you continue to hold it until the flash was happening? You must continue to hold it down for at least 5 - 10 secondsafter the flash starts.
Yes, I continued to hold it all the way until the flash completed and the screen went black and quite some time after that.
When the flash was done did it say "Recovery Key detected" on the screen?
I don't think it did.
If it didn't say this that is an indication that you didn't hold the volume UP key long enough.
So I guess I need to give it another try. Tomorrow I will try to reboot the tablet again and if it continued to go into APX I will do the nvflash one more time.
If all of the above was done correctly and did happen but you didn't get to clockworkmod then what did you get? Did it look like stock recovery?
A black dark screen. No CWM or stock recovery.
It sounds to me like you did the nvflash then tried to reboot into recovery.
No at the time of nvflash I held the Volume UP button and nothing happened. Since then I have been trying to bootup or put it in CWM Recovery but only thing the tablet wants to do is go into APX mode.
So I guess my theory of "drained battery takes it out of the APX mode" is correct. I tried to reboot the tablet several times but it just kept on going into the APX mode until the battery was completely drained. And then it started booting up normally but it went into some installation (probably the stock 3588 that I had downloaded in the previous successful bootup). And then the green android with the exclamation sign came and the exclamation sign was rotating for a second or two and then stopped. And it looked like it was hung. I waited for a minute or two but nothing happened, so I pressed one of the buttons, I don't know if it was Menu or Back button, and all of a sudden clockworkmod recovery screen came up.
I have attached the picture of the screen. It still shows the green android with the exclamation sign in the middle of the screen, along with the CWM Recovery.
One other thing I noticed and I am not sure if it is normal is that if I choose say Reboot System Now from CWM menu and it shows like 10 entries with many No's and only one Yes. I can only use the volume Up + button to go down, if I try to go up using volume Down - button it does not go up. Is that normal? Is the only way to go is go down using Voume Up button in CWM menus? I have a feeling that my Volume Down button has gone crazy and it is not functioning properly and that is what is causing it to go into APX mode at the startup as well.
Anyway I first attempted "Apply SDCARD:update.zip" hoping that it might continue with the stock 3588 installation, but that failed. You can see the messages in the picture. Then I tried the Factory Reset and it was successful. I then rebooted the tablet. But now again it keeps on going up into APX mode. I will have to wait until tomorrow for it to completely drain battery again and then try to reboot again.
Any ideas? I know it is overwhelming and the behavior is very weird. At this point I am trying to bring it back to the stock firmware so that I can get this tablet replaced under warranty.
There are quite a few things that are not acting normal from what I see here.
Did you try to repartition 2048 and 0? If not, I would start with that then I would format everything and re-nvflash a stock ROM onto it. That might clear things up. If not you could be looking at a hardware reset.
I installed clockworkmod per instructions.
When I press the on and volume up buttons I get the appropriate message and then the system boots with the tap n tap (ugh) rom.
I never see a clockworkmod menu
What am I doing wrong?
I am having the same issue!!! I am beyond frustrated right now. I have downgraded to 1.1 and had success during one try and from now on trying to boot into Clockwork it won't let me. All it does is say booting from kernal image and then goes to the splash screen then to the box with the down arrow and continues until it goes right back to the viewsonic birds and boots to the normal rom again.
What the He!! am I doing wrong here? I have already done a factory reset with data wipe...

That is exactly what I was watching and following when this happened to me. Any other ideas? I did however just return the other one after clearing the data and got another one so I am going to try and avoid doing that again.. I am going to try and tread slowly here so I can get things right....
I've had 100% success using the instructions here:
http://forum.xda-developers.com/showthread.php?t=861950
Go to the first link (Dropbox) and, if Windows, download the 2 zipped files. I will say I bought a Viewsonic G tablet back in December and I had to used the older zipped file in the DEPRECATED folder. My latest Viewsonic G tablet works with the latest files.
Unzip the 2 files, combine into one folder, plug in the USB cable, and reboot by holding the POWER button *and* the Vol- button. You should see the initial boot screen but should quickly see a black screen. Run the .bat file (nvflash_gtablet.bat). If the computer doesn't see the tablet, read the above link on how to make sure you've installed the drivers for the tablet. Once the batch file ends, your tablet will automatically reboot. I would suggest powering off the tablet before it reboots as you can install CW_Mod via NVFlash, which is what I do. Grab CW_Mod 1.1 (not 1.2). Unzip the UPDATE.ZIP file and copy RECOVERY.IMG to the folder where you combined the 2 zipped files from Dropbox. Connect your tablet to your PC via the USB cable. Reboot the tablet again by pressing the POWER button while holding the Vol- button. Same thing--i.e. initial boot screen, then a black screen. Either create a batch file or run the following command (sorry cannot remember the thread where I found this, so I take no credit for this):
nvflash.exe --bl bootloader.bin --download 9 recovery.img
This is a quick process. Once the command finishes. Unplug your USB cable from your tablet and hold down the POWER button to turn off your tablet. You can either power it back on or power it back on and check to make sure CW_Mod is installed (recommended). For this, press the POWER button while holding down the Vol+ key until you see the line of text appear in the upper left hand corner of the screen.
Again, on one of my Viewsonic G tablets, I had to use the zipped file contained in the DEPRECATED folder on the Dropbox. I can't remember what the current files did (think soft-brick).
Good luck. As I've said, I've used these steps so many times as I went through every 1.1 ROM and 1.2 ROM trying to find the one I liked and the steps were perfect. At this point, though, while in CW_Mod, I would go through the process of partitioning your system and formatting stuff.
hi guys,
it looks that accidentally i've booted my device into apx mode!
...uploading screens...
br
condi
What do you mean with apx mode?
Where are the screenshots?
How did you reach this?
i didnt wanted to get into apx... accidentally when trying to get root again (after reflash stock rom).. WOW
suddenly device automattically came out from it - still blank-black screen.. some sort of timeout when idle? gr....
now we've got to find out how to enter it with purpose!
will upload mobile-camera photo of that..
Hey its a good news, because APX mode is needed for NVFlash.
As i know with NV flash we can flash our tablet
so the bootloop can be repaired, and more things can be done.
We have to find out how to enter into APX mode.

yeeeeeeeah i was so excited, even wanted to put charger, and keep it in apx mode as long as we could get and make some good things... but it just turned off.
ehhh how did i done it? it was another of several tries to make root, i experimented with turning on/off mtp device in device manager, first of screenshots shows, when apx mode jumped in. i think its concerned in correct rebooting device, but there should be some combination/scenario of behavior to get into apx mode.

only this is what i got before it went out.
Condi,
I also got apx mode once by chance, but i didnt manage to do it again.
I entered into recovery several times while rebooting and pressing the recovery buttons, one of the times it just got into apx...

Hi friend,
thanks for confirmation about it, now i've got hope that we'll discover how to enter apx mode
interesting... now we can find a way to use NVFLASH files to flash custom recoveries/kernels...
i had told ppl to test out stuff regarding NVFLASH:

i am busy currently... but when i am free might need some willing users to test out a few things
Any chance the reset button might have something to do with it?
It "seems" to kill all power, yet pressing it whilst on makes it flash the red led a couple times.. so ovbiously there is some power.
Also, when it connected to your pc and was recognised as an Nvidia devices etc, how did the drivers install? Was it something handled automatically by auto update, or had you previously installed drivers yourself trying to find it another time?
Edit: Just too add, has anyone tried contacting Nvidia about it? I sent them an email about it, they just refferred me to their dev section (which ended up being a section for games developers! ) I'm pretty sure they confused APX with APEX. So I email again but no response since.. perhaps if a few of us send through they might sweat a bit and give the answer . Figured we'd possibly have more luck dealing with them than Sony (even though I realise Sony would be the all-knowing in this)
OK, I just stumbled onto this thread where defsix has found a switch inside the tablet.
I can't see the picture but could this potentially be a s-off switch or something like that, that could allow us to either flash unsigned zips or get into APX/NVflash stuff?
this could lead to an unbrick?? do you think that i may better wait for this (or for any other way to unrick) or to go and try to make it replecade by another one?
Well... I recommend waiting just a little bit more, my reasoning being:
There are only 2 potential outcomes for taking it in:
1. All sweet, they fix it or replace it
2. They send it away, discover you've messed with it, log your serial number and label your warranty as void.
If this can't fix it soon enough I'd recommend just sending it back and taking a chance - I mean what the use in still having a warranty for a perma-brick when you could chance having it fixed only risking your warranty (not like they can just keep it after they check it out).
I'll check it out tonight possibly (aus time mind you/+10 hour GMT) if the gf isn't raging at me and see what it let us do!
well then, one day or two days doesn't change anything, i can esaly wait till tuesday/wednesday, if i have to send it to them, and the warranty void...well then...it's just my fault after all...but i can wait 2days..

unfortunately not, but maybe something can be discovered through that way
OK so i got home early and just cracked it open (quite literally - a little tab snapped )
So all I can gather so far is that switching this switch to "off" just kills all power. The tab will boot with ac adapter connected but not without it.
All the combos I could think of failed ie
- power on + vol up
- Power on + vol down
- power on + vol up + vol down
- power on +reset
- power on + reset + vol up
- power on + reset + vol down
- power on + reset + vol up + vol down
Nothings changing besides the fact it need ac adapter to turn on
(usb has been plugged in too)
Any ideas?

Looking at that original post, I'm pretty sure that's actually just a battery power kill switch. Between the fairly obvious PCB labelling and the position on the board, it would seem to be a purely hardware function. If I got a closer look at the whole PCB (don't want to open mine up just yet), we might be able to see something enlightening, but at this point, I think its just a power switch.
Yeah my thoughts are similar to that. There is nothing else visible at that level of tear down, It must be there simply for sony techs to quickly turn off the battery without dismantling everything.
And until someone gives us a solid reason to pursue the internels, I'd recommend staying away from opening your own tabs. The way the tablet is clipped/taped together, it's either gunna come off easy, or be a ***** like it did for me and snap something. (there's double sided tape as well as clips.. took some firm force to peel it away and when it finally caved, it snapped open in the blink of an eye snapping 2 tabs! booo.)
I can't imagine there's really any promising hardware to boot to apx mode, when people have already gotten there on software alone
yeah, i also think that is related to battery. i disassembled my tab few times, tried some combinations with on/off internal switch, no luck with apx. also tried to ground 'charging' socket - all one by one pins of it. without result. also tried special service microusb cable, with 3 options with resistors - which i use for example for galaxy s - to force download mode - without luck on sony..
about grounding - testpoint - a lot of sony ericsson phones had backdoor in that way, simple grounding one point of service interface.
today i thought about nfx services - they're involved in all of that recovery mistery, decrypting update.zip, and i think that also in apx thing.
apx mode appeared when i was trying to get root - again after hmmm... 5-10 failed try. so maybe nfx logged some number of reboots, reboots in random time, when copying, when some adb commands where running, and forced device to apx mode?
of course its just a theory
Yes, I know this is a common issue. But My Gtab is really stuck. I tried days of following the stock Bekit install. Everything installs just fine and after the nvflash it goes right into the opening screen and starts up normally. Never see birds.
The issue is if I power off, it cannot reboot, always goes to APX mode. I tried several times.
If I run a command such as nvflash --bl bootloader.bin --sync --go I can get back into the startup screen and the tablet runs normally.
There must be a file missing that is part of the normal booting sequence. Is there something missing that the stock install doesn't do?
Yes I have installed CWM and repartitioned and cleared the data. Many times.
Can run the tablet fine if I start it from APX mode, just can't start it from the power button.
I also tried to update to 3588 with same results. Nothing allows a boot from the power button.
I also tried all the files on the "dummies" site. 1.1 and 1.2 install and run just fine, It's just if I power down the tablet. I only get APX mode when powering up.
I also let the tablet update over the internet to version 1.2.5699. It downloaded, then did a restart and went into APX mode. When I forced a boot in APX mode it came up with an android and a red triangle. Another APX boot got me back into version 1.2.4349
Even if I do a reboot from CWM it shuts off tablet and then the power button goes into APX mode
Any help is greatly appreiated.
Try this. My old Gtablet got stuck in APX mode....was like that for about 8 or 9 months until I followed the link in this thread here...

Could be the contact portion of the volume rocker is stuck (I've heard of one user with this issue). Remove the back cover & disconnect the volume switch connector at the motherboard (see attachment) and then try booting.
Al
Tried tcrews suggestion. Same result. APX only on power on. Only thing different was the partitioining 3 times. Didn't work.
Volume button works perfectly. When I am in the tablet, it adjusts volume up and down correctly.

Tried that one already. Think I am going to just toss it and give up on this and just assume there is some sort of hardware problem with this Gtablet.
I must have reflashed it at least 25 times and spent days on it. I give up. Shame it works fine if you boot it from the APX mode, just not from the power button.

Tried tcrews suggestion. Same result. APX only on power on. Only thing different was the partitioining 3 times. Didn't work.

Did you do all the partitionings ?
Like I said, mine was stuck for near 9 months (just kept it charged and running...if it shutdown would APX boot it).
I tried every nvflash fix that was posted but when I followed the one I linked exactly, it worked. Shocked me since I had tried so many other sure fire methods didn't.

Before you give up, do this for me.
Get bekit's standard 2010110500 zip file. Edit the batch file (or shell script) in it and remove the ``--go'' parameter if there is one. Flash the images. The tablet should remain in APX mode. Now run this command:
Code:
C:\SOME\PATH> [B].\nvflash -r --read 2 a2.img --read 3 a3.img --read 4 a4.img --read 5 a5.img[/B]
After the command completes power the tablet off and immediately boot it back into APX mode. Run this command:
Code:
C:\SOME\PATH> [B].\nvflash --bl bootloader.bin --read 2 b2.img --read 3 b3.img --read 4 b4.img --read 5 b5.img --go[/B]
Let the tablet boot into the Tap 'N Tap desktop, then power off. Put the tablet into APX mode and run the previous command again (change the file names to cn.img). Now you will have 3 sets of img files. Upload all of them somewhere so I can compare them with each other and with my bekit img files.
If everything checks out ok, I'll give you another nvflash command to run and if that fails, you can give up.
I've tried all techniques posted and I can't boot anymore and don't see birds either.
I can nvflash all day long but once it shuts down, I need to use nvflash to boot it up again.
Go it.
I used nvflash to stock 1.2-4349 as I had been doing according to these instructions:
slatedroid com/topic/22124-how-to-recovery-when-gtab-does-not-turn-on-and-stay-in-apx-mode/
Then, after booting to the main screen, I let it download 1.2-5699 and shutdown.
I'm still in APX mode at this point.
Then, I referred back to those instructions and and held Vol+ along with power but I never let Vol+ go. It brought me to the blue Android recovery. I ran 'update.zip' right from that menu and it brought up something different I had never seen at the bottom in yellow text (unfortunately I was so suprised that when I grabbed the tab, I hit the home button to reboot) but it said something like /tmp/bootloader.bin=[0]....
I pressed power by itself and I finally saw birds. 4 days of this **** I'm leaving it alone for a while. :-D
I have a fairly generic Chinese tablet, a Neutab N7 (not a Nexus 7), but I have no idea how to enter the bootloader/fastboot mode.
Using adb, "adb reboot bootloader" or "adb reboot-bootloader" just makes it reboot normally.
From a shell, doing "su reboot bootloader" also reboots normally.
I tried Quick Boot from Google Play which has an option to reboot into the bootloader, but it also just ends up rebooting normally.
While powered off, I tried holding power and volume up, power and volume down, and power and both volume up and down, but they all just boot normally.
Doing "adb reboot recovery" does boot me into recovery mode, but the menu doesn't have a bootloader/fastboot option.
Does anyone have any idea how to enter the bootloader/fastboot mode for this tablet? Any help would be appreciated.

why do you want to enter the bootloader? and have they made any roms or cwm recovery for these types of generic android tablets?
[RESOLVED] finally, ROOT for Neutab N7 pro tablet.

Having been looking for this information myself i'm sharing real quick here what i've found. Scouring the net all over i've found NOTHING specific for these Chinese tablets but after finally getting on the scent of VROOT I downloaded and tried iROOT essentially a one-click rooter the .APK **DID NOT WORK** but the PC version **DID** can be found by googling iroot or vroot.
RE: bootloader, i've still found no way or any good info on entering the bootloader AFAIK this is locked and may not be possible without some good hard hacking on the firmware, I DO KNOW that if you try entering the "bootloader" with a reboot manager on the device u will find yourself at the "NeuTab" welcome screen and stuck. Fortunately at least in my experience, letting the tablet battery run down low you can boot back into it and root condition is still good.
Hope this helps somewhat I know its an old post but a lot of people have been looking for this info have yet to post on authors site confirming that the NeuTab also works with his software.
peace.
VE3UND
BTW I forgot to mention the site and the software (ALTHOUGH IT STATES OTHERWISE) is in Chinese. A leap of faith needed there I know but i confirm this method works. l8z
BTW^2 ALSO the android version was KitKat as received from the mfg, also have been told that Jellybean will install on the tablet after rooting and maybe is now included with device but don't quote me on that.
all in all a really nice tab for the price, especially now we have root biggest missing option: GPS but you can tether to another device with gps if you need to. Also no built in USB HOST MODE. //out
I've got the NeuTab N10 and can't get ADB to see it at all. How did you get ADB to work with your N7, were you able to find NeuTab ADB drivers somewhere?
So i recently came across this tablet in my stuff... something i picked up for the wife a few years back.
I also came across this website.... http://neutab.com/info-detail.php?InfoId=11
It has all the tools and programs that the company uses. includes all files for development of their entire line of tablets.
Thought this may be useful. just click on the link that says pheonixtools.zip and it will take you to a back end file server... This tablet is about as open sourced as it gets... so... this leads me to ask a question i have been struggling with for the last 2 years of being a member on this website...
can anyone... please... help me develop my first recovery and custom rom for this tablet? I just have never done it all the way... i have set up a couple things here and there... figured out how to strip the stock recovery and boot... but never got further than that.
Thanks for the help.
• Unzip phoenix tool.zip you just downloaded; (to open a .zip file, download WinRAR)
• In the folder of phoenix tool you just unzipped, depending on your system specs, select "drvinstaller_X64", "drvinstaller_x86" or "drvinstaller_IA64" to install tablet driver; Or you can run all three driver installer and at least one will work;
• Run "PhoenixSuit.exe", select "firmware" tab;
• Click on "Image" button, choose the firmware you just downloaded;
• Turn your tablet completely off (by press and hold power button for 20 seconds), press and hold "volume -" button, connect tablet to computer via usb cable, keep volume button held, press power button 10 times repeatedly；
• The phoenix tool should recognize the tablet. On pop-up dialog window, select if you want to format and wipe out everything on your tablet；
• The phoenix tool will start flash the firmware to the tablet. Wait till it is done；
• When upgrade is finished, disconnect your tablet from computer, press and hold power button for 10 seconds to quit upgrade mode. then press and hold power button for 2-4 seconds to turn tablet on；
Congratulations! Your tablet is now refreshed.
Ok so I have a NueTab Air 7 Android and I have talked toto their customer support which did neurologist absolutely no good. I have been trying to hard reset my tablet and do a factory reset by holding down the volume up and down keys and the power keys until it gives me the option of rebooting. However, there is no option for a factory reset. Only a Recovery mode, Fastboot mode, and Normal mode. I tired the Normal and Recovery an both sent me back to enter password that I can't rremember, which isthe why I'm resetting it lol. Finally I chose the Fastboot option and now it is stuck on that option and has been for almost an hour. It willwas not let me power off, try to hard reset, it is literally stuck. And it is a hundred percent charged. I do jot hav the optiontime to connectbe the tablet to acall Windows computer at this timetime, as the forums I have read say can possibly fix the issue. And what a surprise the customer service phone number for this specific tablet does not know how to fix it!!!!! Not surprised at all. If anyone at allthe has any ideas or knows what to do or howsomething to fix it please help meme. I'm very frustrated to say thethat least and in desperate need of help. Anything would be immensely appreciated. ~Melissa
How to identify the exact firmware of the N7 after this page (Oficial NEUTAB), I have 3 options but that IMEI series is nowhere in the table.

I would love to root this tablet purely because it's my daughter's and some of the games she likes has some real funky permissions That they want! A custom rom would be nice but I will be satisfied with being able to revoke some of the permissions that the apps want to have access to.

I have yet to be able to download the zip or the firmware software. i got root with kingo pc version but that's pretty much it and I can't change the route manager because once I delete that then I don't have root anymore and can't add another one. Also I have yet to been able to get into or see download mode on this either. It just stays on the screen with the name on it and that's pretty much it. no bootloader unlock either
