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!!!

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
Hey everyone who reads this.
I'd like to start my topic with apologising if I post this in the wrong section.
So, I have a LG Spirit H440N LTE for about 3 years now, maybe a little less. I've always taken good care of it, both physically and in updates / security wise aswell.
My phone has been working flawlessly until the last 2 days. 2 days ago i was charging my phone, and when it vibrated (meaning its 100%) I pulled the cable off, and pressed the power button (power button locks - unlocks the screen) the screen didn't turn on. I was like "wow that's strange" but didn't care much, i just kept pressing the button every 5-6 seconds, nothing.
At that point I pulled the battery out, let it sit for a short time and then put it back, start the phone, I felt the vibration (meaning it's starting up) but no screen, so my first idea was that I need to get a new firmware and completely reinstall my phone, as it seems like it got bricked.. for no reason, by itself ? Strange thing but I accepted it and literally been googling for 9 hours now and I find more and more issues.
After I got LG FlashTool, drivers, and even 3 different firmwares, I wanted to start the phone in download mode to start upgrading, but even though I held down "volume up for 5 seconds and then put the usb cable in" nothing happened, no screen, my PC didn't recognise the phone either.
So I got a little bit mad and pulled the cable out from the phone, I wanted to remove the battery, but out of nowhere the phone suddenly started loading in, screen working completely fine, i could do whatever i want, so my first thing was to do a hard reset. After the hard reset I set up my usual stuff (important apps etc) and I locked the screen so my battery won't go down. Little did I know, I ****ed up again, because ever since that happened, I can't get my screen to work again. I tried everything I could but my PC still doesn't recognise the phone (even after a LOT of drivers being installed), charging the phone doesn't do anything. Regardless if I remove - put back the battery no screen, no screen in download - hard reset mode either, it's just completely black.
I'd like to have some sort of help, because I am just completely out of ideas, I really feel like a firmware change could fix the phone, but if the computer doesn't recognise it, I have no idea what to do.

You might be having hardware issues, such as a faulty power button. If you are the type of user that frequently presses the power button to lock/unlock the screen, this leads to excessive wear on the button components, this is why some users prefer to use the "tap to sleep" and "tap to wake" feature, to avoid wearing the power button out. On my LG, this feature is called "KnockOn", it's located in Accessibility settings.

The problem I have is with the galaxy z flip 3, it worked just fine inthe morning but after it ran outta juice and I charged it to a certain percentage, it stopped working properly, and got into an infinite boot loop, I tried forcing it to restart by long pressing volume down+power , but it didn't work, then I tried opening the recovery by long pressing on volume up+power and yet it also didn't work (I think that maybe it's because it was trying to boot at the time), so have you guys any solutions , please do help me cuz this phone really is important and with all honestly, isn't even mine XD, I'll be waiting for an answer
Your failsafe options are contact Samsung or do a factory reset (and then potentially contact Samsung).
If you can't boot it to anything, the only real option you have is to flash firmware, which likely won't help without wiping.
Unfortunately, not booting doesn't have a whole lot of options that don't wipe data without being rooted. Even then, you'd need recovery.
I see, then I may consider giving it to samsung, as long as they won't reset it, cuz the only reason why the phone is so important is because of the data, altough, isn't there any other way to acess recovery? Cuz I had this problem with the s10 before and I fixed it somehow (a certain Bixby key combination), but this time it seems there isn't any hidden combination.
Samsung is going to reset it. It's a required first step for them to do any work on it, even if the work has nothing to do with the software. What may help find a way to recover the data is starting with how it got to this point. Did you install anything new, change any important settings, or anything else that could have been a part of the issue? If not and it is an unexplained hardware failure, the data is likely gone already.
If it's something you might have installed or changed, it's possible that putting the phone in safe mode and undoing it may solve the issue and let you boot normally.
Booting into Safe Mode:
Make sure the device is powered off (charging is ok, as long as it is not currently trying to boot)
Hold the side key to power on and continue holding until "SAMSUNG" appears and the device vibrates
Immediately release the side key and begin holding volume down until boot completes
If the device has booted into safe mode, you will see a translucent "Safe Mode" in the bottom left

Well I just asked the original owner (my mother), and apparently she doesn't remember downloading anything new into it, and it just went crazy by itself, also something else I wanna note, I tried charging it and it booted into recovery all by itself, I taught it was weird but Still went and wiped the cache and then when I tried restarting it it suddenly ran out of juice once again, also, it's second display shows some weird curruption/bug or glitch-like lines. So based off of this, can you really find the origin of this problem and if there is really any hope of saving it's data XD. Thank you btw, and once again, I'll be waiting for an answer
There are hundreds of reasons it could do that, including a faulty board. Thanks to the removal of physical sdcard support, you'd need to get it to boot into something with at least adb support to pull anything off it. Stock recovery doesn't provide any ways to perform a decent backup, but it sounds like the only option that wouldn't wipe the device didn't work.
I see, alright, thanks a lot, I'll consider resetting it
It may be worth trying to flash firmware first. Go into it knowing it may reset the device or leave you needing to reset it, but it doesn't hurt to try if you run out of safer options.
Same here, same symptoms, happened in front of my wife's and eyes face. We are fairly techy and understand our way around our devices. We also noticed the device crashed then would make it all the way to the home screen launcher and before catching signal the crash would cause a restart at that point I went in and did a cash swipe rebooted right back into recovery by itself then I unplugged the cable and it was acting as if it has a dead battery but when the cable was last plugged in during a couple of crash and then restarts all the way to the home screen I know the battery was at 70 something percent. My next step is going to probably be flashed the current firmware that just released on top of it as a dirty flash and see if I can get it to boot. If not then I'm going to do a hard reset and see if that works. When plugged in it automatically starts exhibiting symptoms as if the buttons are stuck. The devices in the OtterBox and it's fairly brand new I would say mint. Not dirty or any smudges either. all I'm saying is I'm one of those type of technicians that say yeah right when people say it just happened I don't know where but this actually happened I don't know when I was able to witness it. I'll come back and let you guys know what works and what doesn't. (By the way excuse my grammar I was voice typing while driving )

Same here, same symptoms, happened in front of my wife's and eyes face. We are fairly techy and understand our way around our devices. We also noticed the device crashed then would make it all the way to the home screen launcher and before catching signal the crash would cause a restart at that point I went in and did a cash swipe rebooted right back into recovery by itself then I unplugged the cable and it was acting as if it has a dead battery but when the cable was last plugged in during a couple of crash and then restarts all the way to the home screen I know the battery was at 70 something percent. My next step is going to probably be flashed the current firmware that just released on top of it as a dirty flash and see if I can get it to boot.

Hello everyone just a quick update. Once I got home I plugged the device into a Samsung fast charger and Samsung OEM USB type-c cable and realize the device booted all the way to the home screen but register the same battery level as I mentioned above. Device was working as if nothing happened to it. So I updated all the apps on the Galaxy store then updated all the apps left over from the Google Play store, I then proceeded to check for a firmware update because I know the April update just released and installed the update with no issues. Updated the apps that needed to be updated again somehow there's always something and unplug the device from the power cable. Everything was working if no issues about half hour later the device cuts off and does not want to power on. FYI I already had my wife contact T-Mobile and get a warranty replacement we only paid $5.00 so my thoughts and conclusion on what's going on something happened to the battery or it's defective. Btw we only use Samsung OEM cables and equipment at home and in the car while connected through Android auto. it's only working while being plugged in it's not charging all the way even though it's registering it's charge level while the device is on.
Good day, this would be a pretty lengthy post. I'd like to describe my experience clearly since I don't know what I possibly skipped over as I am very positive that my efforts have been correct basing on prior XDA forums. I even made this account solely for posting this to ask for help formally along with archiving this problem I'm having for those having a similar experience.
I've been working on my mom's phone this whole day and there are fruits of my current hard work. I am immensely stressed and despairing with my situation.
The Problems
Infinite boot looping
Can't access the recovery menu (power, volume+, even with home button)
Can access the ODIN / Download menu
Can't turn off either (holding down power button has no effect)
What I've done so far
I read XDA forums about similar experiences. Can't really access the recovery menu so I've factory reset.
We live in the Philippines and this phone is open line, so I went with those requirements while searching stock ROMs.
I downloaded the stock ROMs of the phone model via galaxyfirmware.com which was positively shared in the forums.
Did trial and error with it and eventually got the right one. I have formed a level of understanding with the filenames and eventually knew which is compatible.
Used Odin3 to Flash the BL, AP, CP, CSC, and even go Nand Erase and got the PIT file inside the CSC (Opened it using winrar)
The flashing is actually successful and quite fast to be honest.
The phone reboots itself and shows that it is still sadly boot looping.
Also, despite the several files used for the Flash, still can't access the Recovery Menu.
With that said, I have also tried using Frija which automatically downloaded the stock ROMs based on the model name and CSC type. Placed it in ODIN again and no changes, still boot looping.
I also can't put the TWRP I got here because of the FRP Lock, which can be undone via the settings of the phone. But since it's boot looping, I can't really do much about installing a custom ROM.
Currently, my dad is letting the phone drain its battery, since we can't really turn it off. The phone model doesn't have easily detachable battery as well, unlike the old days.
For some additional notes of what happened prior to this incident
My mom was just playing with her phone as her usual days went on. That day, she installed a new hotel-themed game she saw on Google Play. As I assume that it's from the app itself and not on some shady apk website, I saw no problem with it and didn't think it was the cause of all this. I went with the theory anyway and with the flashing, using CSC instead of HOME_CSC (which apparently saves the existing data on the phone from wiping), and even used the Nand Erase in the end. It's still stuck at boot looping.
I would appreciate anyone's reply to this discussion. I am truly desperate to fix this for my mom. If worse comes to it, I'll save money to buy her a brand-new phone.
You don't have a working android, so you won't remove the RFP. TWRP will not help you with this.
The symptoms you describe indicate a defective power button.
You manage to enter download mode because the power button is constantly on.
Because of the constantly on power button, you have no way to turn off the phone. Bootloop can also be the result of a constantly on power button.
To sum up, you should fix the power button.
1. The easiest way is to blow with compressed air and press the edge of the button with your fingernail, rapidly releasing the pressure. Perhaps the fuzz has blocked the button. Unfortunately, this rarely works.
2. Take the phone to a local service center.
Hi ze7zez! Me and my dad greatly appreciates your insight and we were definitely enlightened on this angle.
We didn't really think that the power button was stucked pressed on because you can clicking sounds when you press on it. The phone never had problems with the buttons along the 6 years it accompanied us, perhaps its age does start to show.
We're going to look into it tomorrow. Thank you very much! You gave us the idea that it may be shorted inside or some sort. Thank you again!
A bit of update.
I pried open only the back case of the phone so I can see and clean up the power button. I used tools specifically for it and made no damage on the phone during the process.
We couldn't really see anything busted from there. The buttons on the circuit still do the neat clicking sounds on it. Battery still looks the same.
Testing out the theory that the power button was stuck on:
We tried to only press and hold the volume down and power button. It didn't go to the download menu. We needed to press down all three together to access it. It is confusing since we believe it would be a power button issue too, as the phone instantly turns on by itself when plugged to a power source (it's completely drained by now and we still can't turn it off manually)
Perhaps it's an internal circuit problem with the power button? It's confusing with the fact we still have to press on it to access the ODIN menu if it was like "on" the entire time it's looping.
Thank you in advance for further insights.
Try restarting by pressing home, power and volume up all at once.
Hi Pranav2406,
I have tried that as well in order to access the Recovery menu to factory reset, but no luck.
We have given up on repairing the phone and went out yesterday to buy a new one in a rush.
We will still send this broken phone to a repairman.
If he fixes it, I'd ask what he did on it so I can post an update on this problem as well.
It's better to let the expert troubleshoot it.
I do suspect the problem in the phone's hardware. I'm pretty confident with all the stock ROM flashing I've done so it's not a software problem.
Thank again for everyone's insights.
Perhaps this case is too much for an amateur to fix.
