Please could someone help. Today after installing some apps and games, I powered off my tablet. Later when I tried to power it up again it started and got to the tap n tap screen, reloaded a few times and then The screen goes blank! It won't do anything not even starting it up in recovery mode. Anyone that can help?

The best solution I would say is to follow the instructions listed for flashing the nvflash_gtablet and preferrably with a Linux system.....I couldn't get it work with Windows as the driver was no where to be found......It does work....but took me like 4 days to figure it out!!! Now, everything is working great!

So I've had the G-Tab for a month now (stock 1.1) and decided to change the rom to Vegan-Tab and followed these steps.
1. Installed CWM fine no problems.
2.Repartitioned, again fine no problems.
3. Tried installing Vegan-Tab appeared to work fine until after re-boot the tab got stuck on the three birds.
4. Realised I should have run NVFlash before installing new Rom so ran NVflash, again appeared fine until re-boot. This time I was not able to turn the Tab on (Power Button not working)
So now the only way I can turn on the device is to run NVflash (tried with and without CWM) and leave it on all day.Power button works fine for entering sleep mode or for turning Off but just will not turn the Tab on. Any time I try to install a new Rom I get through all phases until the re-boot, then nothing. Guessing I am maybe stuck in APX but how do I fix?
Yes... you're in an APX loop. Try the following...
1) Do an nvflash to start it up and immediately do a datawipe. If the resultant restart doesn't fix it...
2) Goodintentions has a GTablet for Dummies website with known good nvflash images. Follow his instructions carefully.
3) If none of that has worked... Sometimes the only way out of these loops is to force the tablet to reload a stock bootloader. The following procedure will do that:

This guy has already tried all those tricks. I was the one who sent him here. Anyone else know how he could fix his gtab? I ran out of ideas.
If that's the case I'd be interested in seeing it. Ive never seen one that failed all of the above... Perhaps a hardware problem?
Logs would help...
Any error messages during nvflash?
Any other odd behavior?
Be happy to help if you can supply more info.
Hey, yo, try my new code detox in the home page. Can't believe I forgot about that.
http://viewsonic-gtablet-for-dummies.webs.com/
Thx for your input guys, especially goodintentions. Ended up contacting Viewsonic and sending unit back. If they repair/replace it great, if not and I get it back I will try your detox. Either way next time I will follow your directions to the letter and won't get carried away this time. I will also be sending a donation/beer money your way! You guys are great for us dummies.

Will VS replace the unit even though you flashed a ROM to it. I was wondering if I should send mine in. I NVFlashed it and now I get nothing. no screen, no recovery mode, no APX mode. It is not recognized by Windows when plugged in nothing but that little red glowing light when I plug in the power jack.
If you can't turn it on, then they can't turn it on.
I'm guessing what you have is a hardware issue. Just a coincidence that it happened as you flashed in something else.
I'm running Prime 1.7 I never had any problems with my tablet. It has the creaking and light bleed. I was watching netflix the other day and watched all the way till the battery went completely dead 0%. I got home plugged it in and it charged up all the way but now the screen wont turn on. If i connect it to the mini hdmi i can see everything on the tv but screen still wont turn on.
I've tried:
Fixing Permissions
Clearing Cache
Undoing overclock
Removing SD
Turning it all the way off waiting then turning it back on.
Adjusted the Brightness
Changed Wifi.
I cant factory reset or anything in CWM because it doesn't show up on the tv through hdmi and i cant remember the each button pushes to do it blind.
Any Ideas?
Mine went blank once but that was the adw launcher. Rotating it fixed it and i was able to choose stock launcher. If nothing works you can try screencast to see the recovery on PC if you have Android sdk setup.
Did you try to hold down the Powerbutton till it switches off to make a correct Restart?
When the Tab is running hold the Powerbutton till it's off and wait till it starts again.
Normaly that helps with SOD.

You should press the power button 10 to 15 seconds...
So far nothing worked. I'm on stock launcher also.
I've tried to resetting it over and over still nothing.
I attempted to letting the battery die completely again.
Placed it on the dock and nothing.
Thank you for the suggestions. I will update if i ever solve the issue. I'm going to try screencast, but i never used it before.
I got screencast to open up and running. however it wont work in recovery. ADB recognizes it. I keep getting a blank screen. Any ideas?
I'm thinking the best option would be to nvflash it to stock and RMA it if it doesn't work.
NV Flash
Hi
if nothing else seems to work then NV Flash might be the best idea.
Could you share the BXX(First 3 digits of serial number)?
Thanks
Hi XDA,
Today I bought a tablet, the 10" Tablet PC by Qware, model QW TB-9010.
Hardware looks fine, but I'm having some issues:
First issue is that I can boot the tablet, but when I unlock it, all I see is a black screen with the notification bar at the top which works fine, but the rest is empty and black. When I press the Home button a couple of times, the wallpaper flashes up, I see the appdrawer button but then it crashes to the black screen again, so can't do anything on the device itself.
Next, the screen stopped working, I have to use a mouse to unlock it, I'm trying to fix this with new firmware but thats where we arrive at the biggest problem:
Not in the manual, the manufacturers website, or by just trying, I cannot find out how I get this device in recovery/update mode.
Support is VERY poor for this product, but I'm guessing firmware like Uberoid will work on this device, but can't install this because it doesn't boot in recovery mode or w/e.
So if anyone has any idea how they can help me or have any tips? Please let me know!
I want to fix this thing!
How long did you use this thing ?

A couple of minutes...
I have an unlocked HSPA+ Galaxy Nexus imported from the UK to the US. Ordered from Negri Electronics.
It's not rooted or modded in any way.. Mainly because I don't know how to. As far as I know, it's running stock ICS.
I was using it normally, (using the fb messenger app if it makes any difference) when it suddenly rebooted by itself. The Google logo comes up, then the start up animation, and sometimes the home screen will appear but is not touch sensitive (i cannot slide it to unlock), and then it 'hangs' and the screen goes black. Repeat.
I've tried to fix this by myself and there's a video on youtube (sorry, noob here. can't post links. video is by robbidwv and title is "my galaxy nexus won't boot..") of the same problem that I have, but the posted solution doesn't work for me.
So far, I have entered Coin Mode and pressed Start. Entered Fastboot mode and gone into Recovery Mode (no options appear after that. it just starts booting up and the loop begins), and I've also tried Restart Bootloader.
I've almost given up. Now all I want is to extract my SMS, if they're still on my phone. I can't access the folders on my computer because it won't boot up and connect. Is there a way that I can extract my SMS by using DOS in either Coin Mode or Fastboot mode?
Or even better, does anyone have a solution to this boot loop problem? I'll contact Negri Electronics tomorrow and hopefully they can send me a replacement.
Please help!! Thanks
that problem just started happening with me an hour ago!!
i hate this!!
we need a solution please!
Hey guys, sorry about the issue.the major problem I see here is you wanting to retrieve your txt messages, which might be possible with a little Modding, but if yourwilling to lose them to get a working phone back, then this is what your going to have to do. Make sure your phone is completely off. Hold the 2 volume buttons and the power button together. You will get into a mode with an android Guy. Press the volume button up or down until it says reboot recovery at the top. Press the power button. It will rebootand come to a screen with an android. Hold volume up,down and power at the same time. A menu will come up. Go down to wipe data. Click it, and after it is done reboot. Your phone should work now.
If this helped you, or you simply appreciate me taking the time to write this out then please press the thanks button
Hey!
Thanks. Yeah I 'fixed' it already. I was just about to post something similar. After a while I just gave up on trying to recover my data. Good thing that Google syncs everything so the only issue would be recovering my messages, which I decided weren't worth sending it in for a repair which would probably not be able to recover anything anyway.
The thing I didn't know about was to press power + volume up WHILE on the recovery screen. I thought navigating to the recovery screen was it!
Still, this kind of sucks. I love my GNex, but I can't help but be slightly pissed seeing that my crappy iPhone 3GS never did this in the 2 years I had it. Oh well, hope it doesn't happen again!
hey guys! i also did a complete wipe on my phone and got it working again!
but i wonder why this happened in the first place?
last application i installed before the crash was double twist, i dunno why but i feel that it was the reason behind the boot loop!
Sorry for reviving this thread, but I just had this happen to me TWICE!
It happened to me first last Monday, the 23rd - the phone crashed when trying to send an email with an attachment - and went into a boot loop - Google logo would appear, no make it to the animation, and reboot....
I performed a full reset and things worked again. I didn't install all the apps I had before - figuring it must have been due to some app messing with the OS.
Well, it happened again to me yesterday! I was connecting to my bluetooth headset when the phone crashed and went into the boot loop. Full reset worked again, and I've installed even fewer apps - essentially only those that I use on a daily basis.
My phone is still on 4.0.1 and I'm hoping once 4.0.4 is pushed this may get resolved? I have a canadian GNex from Negri. I will call them again (I called the first time, but when the full reset worked I never contacted them again).
I would like to this this is a software issues, and not hardware.
I have the same problem. If you figure it out let me know.
Today my phone also entered a boot loop: [Google logo]->[black screen]->[vibration]->[Repeat]
I tried Recovery Mode, but this is what happens: (sorry for the link but I am not trusted with powerful tools such as outside links apparently, as I have not yet reached the maturity of a person with eight posts... )
dl(dot)dropbox(dot)com/u/53568097/Android.jpg
This is what I see when I navigate to Recovery Mode
For a split second I can see an image of an Android with spinning cogs in his innards, but then this little sad fellow appears. WTF is this?
EDIT:
Oh, and I'm running Android stock 4.0.2, never rooted or unlocked, Swedish. At the time when the phone started doing this, I was using Endomondo, and was about to set off on my bike when it died on me.
Stock ROM galaxy nexus bootlooping after wiping data also.
Hi,
My GNex went into a bootloop so i searched xda and found that factory reseting would be helping my prob. But after wiping the data also its still in going through the loop . Please help .:crying:
So, yesterday I decided to reboot my phone since it was very sluggish for whatever reason. I think it shut down properly but when it came back on, there was a very interesting problem that had come up - it didn't boot any further than the logo screen, which didn't even play its standard animation; it just stood there with the LED on the home button changing colors (like normal). I left it on overnight hoping the problem would be gone, but to no avail. It still hadn't booted when I woke up. If it matters, the only thing I can boot to is download mode. It doesn't let me get to safe mode or however it's called (the menu you navigate with volume up/down and the power button). Needless to say, I was very puzzled. Then I went on and tried to flash the latest kdz since I thought that would fix the problem. I hoped that would easily fix the problem. But no, it decided to be funny and give me more headache. I tried using this guide: http://forum.xda-developers.com/showthread.php?t=2409308 but after step 20 the LG Mobile Support Tool crashes and I can't continue. Sure thing, I will try the Upgrade Recovery that the tool has built in. It properly detects my phone, the software download and extraction goes smoothly. Then I reach the S/W Upgrade part of the process. The few first seconds everything is fine, but then the bar reaches 5% and just stops. Just like that. Now it's been 8 hours since I began the recovery and no progress has been made.
Can anybody help me? I'm lost here...
