Hey, all.
What does the internal reset button actually do? I was expecting it to reset to factory settings, but fortunately for me it didn't do this. I'm actually happy it didn't, as it means I didn't lose any of the customizations I had done or applications I had installed.
I just cracked open the case on my gTablet and pressed what I assumed to be the reset button, a tiny little white switch in the center of the unit. After pressing and holding it for about 3 seconds, the tablet immediately powered back on and returned to its previous state. Everything appears to be functioning perfectly normally and exactly as it was before.
What does the reset button actually do? Do I need to worry about battery meter not being accurate or any other weird side effects? I only mention that because the battery gauge is showing 100%, but the external red charge light is still on.
I'm not sure what prompted it, but earlier today, my gTablet went blank and wouldn't turn back on at all. My son had been playing Angry Birds for an hour or so and I had been using it heavily showing it off to my in-laws, so I thought perhaps the battery had simply gone dead. I had not plugged in the charger the night before, so it seemed to be a reasonable explanation.
I plugged the charger in and the external red light was visible, so I let it charge for a little while, then tried turning back on. I could press any number of different key combinations (power & vol+, power & vol-, holding button for long time followed by short press, etc.) but I got nothing but a black screen. There was no indication whatsoever that anything was happening.
I was assuming something had gone quite awry, but didn't panic. My wife was not quite so calm, but I reassured her that I would be able to find the answer on the XDA forums. Thanks to everyone who has contributed to this great community, by the way!
First, I tried plugging in the USB cable to my Windows 7 laptop and heard the distinctive 'bing-bing,' notifying me that hardware was recognized, so I knew it wasn't dead. But, it didn't show up anywhere, so I checked the Device Manager. Interestingly, there was no yellow exclamation mark anywhere, as I expected from reading some other posts about NVFlash. I finally found it listed under the 'Disk Drives' section as: 'NVIDIA Tegra 2 USB Device.'
I remembered reading about people experiencing problems with the unit going into APX mode, but I also remembered reading about the internal reset button on the gTablet. So, I figured before I attempted to use NVFlash, I would try the reset button first. Fortunately, these devices were designed well and the case was very easy to pop off.
By the way, I was running the stock ROM, but with the TNT 3588 Enhancement Pack (Gapps with nVidia Drivers) provided by edirector. I had also installed the z4root application. I used the default ROM for the first day, but was comfortable with the idea of flashing othe ROMs, as I've done it with my HTC Aria phone. I flashed roebeet's TNT Lite 4.40 and used that for several days before going back to the factory ROM with the enhancement pack.
Thanks in advance,
Calvin
Well,
I've been reading these forums since last November and I don't know of anyone who
has really reported on "pushing" the reset button before!!!
Usually when people crack the case to push the reset button or unplug the battery
for 10-15 seconds it is a situation where they can't get the machine to start and
literally have nothing to loose.
Sounds to me (in terms of 30+ year of different computers) that you did a hardware
reset and boot. I assume something was locked up inside and the reset key released
it to restart.
Glad for you!!!

After updating to 3.2, I noticed that the touch screen has a ton of bugs. I used this program to check the inputs (I can't post links now due to forum restrictions):
Multitouch visible test
Basically if I scroll from far left to far right (Asus logo on the top left of my view), there is always a cutoff somewhere on the screen.
I never or hardly ever notice this problem when I'm in 3.1.
Any ideas on how to fix the problem? Or is it just 3.2 that has this and I should go back to 3.1?
Help is totally appreciated. Thanks!
Update:
Sent in the TF to Asus (to Ontario Canada) on August 9, 2011
Received it back from Asus on August 29, 2011 via UPS
Problem: they only reloaded the OS and did NOT test the touch screen so I have the exact SAME problem... Requesting RMA again
Can you grab a video of the issue?
Plonk it on youtube and then stick the url on here.
Cheers
Video is at youtube:
www(dot)youtube(dot)com/watch?v=ukdzYMKYtFE
Basically a portion of the screen does not respond to touch, and the classic turning screen on and off does not fully solve this problem.
had this problem before 3.2.
my screen have only small places..quarter of inch, random places.
noticed this only after rooting. and with some kernels more than others.
have you rooted?
No root. All stock since I am too lazy to do anything other than install apps, view video and manga.

Quality vid there, top notch.
Have you tried a hard reboot?
And a restore to factory default settings?
For some reason that sounds sarcastic there... but the video was taken by a Desire HD so it's not that good quality. It conveys the point (I hope).
Haven't tried hard reboot or factory default settings because that would mean I have to reinstall stuff and re-setup things like gmail.
Lol dude, i wasnt being sarcastic, for some reason i was expecting some half-assed effort.
Hard reset shouldnt wipe your data.
Hard Reset:
Unplug the power cord and shut the unit off and Press and Hold the power button and the "Down" volume button together for 6-10 seconds and let them both go. After a few seconds you should see a couple of shapes in the middle of the screen called "Wipe Data" and "Android". Wait a few more seconds until the term "Cold Boot" appears in the list near the top of the screens and just press and release the "Down" volume button again and let it reboot. If you own the dock be sure and do this with the dock connected.
Sorry man, I guess my sarcasm detector is pretty off today.
I tried the hard reset and the same problem persists. I will have to see how this can be fixed though (I see that many people have similar problems though).
Thanks for your help =)
might be worth giving asus a tinkle and see what they say.
i just had an episode of an issue that worries me.
I had the tf700 docked and put to sleep by closing the keyboard/tablet. 8 hours later, I pressed the power button and nothing turned on. I thought somehow the battery completely drained, so I plugged in power adapter and still nothing. I tried holding down power and nothing.
Then I undocked, and plugged in ac adapter. After holding down power button for quite a few seconds, i get th screen to come on and the message to confirm tuning the unit off. Apparently the unit has been on but the screen off.
After I rebooted, I find the unit sluggish as if I/O issues again.
I am on firmware .26 US latest. It has been fine until now.
My biggest concern is that I remember a friend of mine describing this issue with his TF101, and said the only way to get it back on was by plugging in the power adapter.
Anyone else can shed some light on this?
I've had this on my SGS2 a few times, and on my previous phone (LG O2x as welll) -- in both cases it was related to issues with deep sleep (and on the SGS2 standard custom kernel undervolting), implying that changing kernels would cure this (or make it immensely worse, hahaha ). Having said that, I do recommend following this issue closely, and if this happens again, I'd reflash .26 from a full wipe. If it then still does it, I would suspect some hardware issue.
Again, to at least provide you a bit of reassurance: I've never encountered the error on my SGS2 again after flashing a (very, very nice) kernel, and the O2x only does it very infrequently now (but has crappy kernel development, at least when I checked last, so I'm still not very satisfied. Might tryCM9 with it or something...).

Before doing any of that I would do a "cold boot." That can solve your problem in its entirety before having to use drastic measures.

what is a cold boot?
it has only happened once, so its probably infrequent. However, I am more afraid of the inopportune times it cn happen. What if it happened when i am away from home with no ac adapter, like on a plane? I won't be able to boot then?

Here is how to "cold boot" (copy and paste from other thread), should resolved your issue.
1. Press and hold down “power button” until the system shuts down.
2. Remove the SD card from Eee Pad.
3. Press and hold down “Volume down” button first, and then press and hold down the “Power” button until the screen appears with 2 icons, one is a droid and one is wipe data and upper left corner should said cold boot linux.) now let go your fingers. Make sure do not press any buttons until the screen mentioned screen appears. If you don't see the 2 icons in the middle of the screen re start from step 1.
5. There’s a line “Press <Vol_Up> to execute, <Vol_Down> to cancel wiping data. Press Volume Up button to execute the “Wipe Data”.
6. After the “Wipe Data” process is done, it will reboot automatically. Then Eee Pad should be able to enter the system successfully.
oh, so cold boot means wiping all apps? have to reinstall everything from scatch r use ttanium backup?
Hi, just wanted to add, happened to me also on my tf700,... I tried factory reset, didn't help, then I tried buhohitr advise of doing a cold boot wipe and that seems to be good.... is only been one day since I tried it, But so far so good... and yes, a wipe does delete your apps if you do a proper wipe.
Thanks!
Samsung Galaxy Tab 2 10.1 Hacked, Touchscreen unresponsive
Hi! I need help with my tablet.
Device: Samsung Galaxy Tab 2 10.1 Tablet, model GT-P5113 TS. This model doesn't have a way to yank out the battery.
What's wrong: Touchscreen is not responding.
Current state: Attempting to drain the battery. Doesn't appear to be turned on. Factory reset apparently performed.
What happened: Sorry, this is long. It is as best as I can remember it. It may be somewhat inaccurate.
Yesterday evening, I was on my Windows laptop and logged into my Google account. I *thought* I used the Google Play Store to install Chrome to the tablet. (I had looked at the html5test website and it said Chrome had a higher HTML5 rating than the Dolphin/Jetpack browser I've been using on my tablet.)
But something went terribly wrong.
After sending Chrome to it, I unlocked the tablet and used both Chrome and Dolphin to go to html5test website. They both scored the same or nearly the same. I don't know if any of that is relevant, but I'm including it just in case.
At some point after that, I woke the tablet with the power key and used my unlock pattern on the dots lock screen.
That's when I saw what I believe was mal-ware in action. The settings menus were scrolling and sub-menus being selected, all by themselves. I couldn't say exactly what was changed because whatever program or script that was running the process was going extremely fast.
When I realized it might be trying to send out data over my Wifi network, I turned off the Wifi router in my home.
I repeatedly held down the power key to turn the system off, but doing so only rebooted back to the useless lock screen which was not responding to anything. The normal method of holding the power button for a few seconds to bring up the menu and then tapping the "Power Off" option on that menu refused to power off the system. Nothing on that menu responded to touch.
Entering my pattern on the lock screen did absolutely nothing. I didn't even see any lines traced when I ran my finger over the screen.
At some point, I pulled out the external SD card. I have no idea if whatever hacked the tablet also put a copy of itself on the SD card.
I called a friend who looked up how to restore the tablet to factory settings. I didn't understand the directions exactly, so I ended up on a screen with a Warning!! about installing a Custom OS. (Holding down the Power + Volume Up seems to get me there)
I left it on this screen, and I turned my router back on and using my laptop, contacted Live Chat at Samsung but they didn't understand my problem. They told me to reboot the device and swipe my pattern several times and then after several failed attempts I would have the chance to use my Google credentials to get into it. But the device apparently never registered that my swipe attempts were failing.
So my device was booted up with me locked out, with the WiFi router on for a little while again. I turned off the router as soon as I realized that. That disconnected the chat session, but since Samsung chat wasn't helping me anyway, I didn't bother trying to go back.
I got the device back to the "Warning!!" screen. Then turned the router back on and searched for how to do a factory reset of the device. I found a video on YouTube and followed it.
I pressed the Volume Down and Power buttons simultaneously, followed by letting go of the power button. That brought up a menu which contained several options, including an option to do a factory reset. I used the volume buttons to highlight that and pressed Power key. A second screen came up and I used the volume buttons and power button to select "Yes" to confirm the reset.
It appeared to have done a factory reset, rebooting eventually.
However, after that, when I tried to tap on the touch screen to move forward through the selections, the touch screen was still unresponsive!
So I brought back the "Warning!!" screen and ran the battery down until the screen was blank and it wouldn't start when I held the power key.
Then I charged it for about 20 minutes and rebooted it. I think when it came back it was on the Recovery menu. I think I did a second factory reset, but not 100% sure. It eventually rebooted after a lot longer than usual.
When it came up, it was saying battery was low. I tried to tap the OK button, but nothing happened. Behind the battery window was the first setting screen to set up the device for the first time after a factory reset. (I think selecting USA?)
I brought back the "Warning!!" screen and left it on overnight so that the battery would run down.
That was about 8 hours ago. When I woke up, I used clear tape to keep the power button pressed down, to ensure that the battery will continue to run down.
____________________________________________
What do I do next? How do I get the touch screen to start working again? It is not a hardware problem, unless mal-ware can break the hardware. The touchscreen had been working fine until this happened.
Should I take the tablet back to Best Buy where I bought it at least a year (maybe 2 years) ago? I don't know if it's still under warranty.
I have over 20 year of experience as a software developer, but not for Android. I am not very experienced with doing anything to hardware.
Should I try to fix it myself?
I have never rooted any Android device and I'm not sure what that means, either.
I've never re-installed the ______ ? (rom? image? Odin?)
I read on this and/or other forums that there's a way to replace something, but the instructions were beyond my level of understanding. I would need the procedures to be broken down into steps which don't assume too much about what I know.
I understand how to download a file to Windows, given a URL for it. I understand what a zip file is and how to extract it. I understand how to press hardware buttons and plug in cables, and do these steps in the order I'm told.
I don't understand what I'd use to get the downloaded whatever-they-are onto the tablet to replace whatever-the-other-thing-is so that the touchscreen works again.
As far as I know, Odin is a Norse god.
The only firmware updates I've ever done are the ones that the device does on it's own through Samsung's updates.
I'd deeply appreciate getting this device back since I have extremely limited funds and probably won't be able to buy a replacement.
Thank you,
Linda

Definitely sounds like malware. You have two choices that I see, either root and custom rom or flash back to stock. Since you are stock you'd just be overwriting your existing install. Read this thread and decide your course of action http://forum.xda-developers.com/showthread.php?t=2203309
Last night I was using the tablet as normal. I sat it on the pillow next to me to grab my TV remote and I saw a pop-up on the screen out of the cornerbofbmy eye ,which was out of place. There was no reason for any kind of pop up.
This wasn't a notification. It was a pop-up window right in the center of the screen. The same place where the the window appears when you hold power down and you get the menu of Power, Restart, etc…
And in fact, all I saw of this pop-up was "… .. is turning off" and then it did.
But, it immediately came back on and the Android logo appeared like always then TWRP recovery screen flashed for a second and it went off. I have not been able to get it on since.
I have held the power button in for 30 seconds and I have tapped the power button. I have done every combination of power buttons with volume button and then repeated those with it plugged into the pc.
I just removed the back of the tablet and the battery out reading spot on. I'm confident that the battery is not the issue.
Now I'm lost on where I go from here. Is there a method to bypass everything and fire up the screen to see if that works?
I'm open to anything.
Any help would be life saving.

It sounds to me like you got the ota that killed your tablet. Is it the original shield tablet? You should check the serial to see if it was recalled. I don't know the address but just Google Nvidia recall battery, you'll find it
Sent from my SM-G386T1 using Tapatalk
Yes, it is an older tablet compared to the newer "K1 no stylus" version however, when checking the battery number it said it was a B01.
The idea ilof getting the kill switch never occured to me as a possibility due mostly to the above mentoned not being a candidate but also because i didnt realize the kill switch completely shut it off and somehow render the power switch useless.
I was thinking it caused a bootloop or something like that. My tablet has zero signs of life.
I will have to approach Nvidia tomorrow and hopefully get this somehow sorted out.
If this was in some way my fault and I misread the battery info i still shouldnt have recieved the kill switch because I never activated a replacement. Correct?
Is this is somehow reversible? I imagine its not since I can't power the damn thing on. I have 3 other Shield Tablets in the house. 2 OG tablets and 2 new K1s. If there was a method to use a working tablet to resuscitate my dead one, that'd be interesting.
I'm getting ahead of myself tho. I feel this is an Nvidia error and should be taken care of by them.
Word if caution there's guys going around on craigslist emailing about shield tablets that are for sale asking for serial number to verify warranty..only to submit a claim for the recall tablet .. Happened to my brother..
