Formatting Tablet Help

OK, so my little 9 year old brother got the Acer Iconia Tablet A100 so he wouldnt feel so left out that everyone else in the household has a tablet but not him, well he thought he would be smart and turn off the wifi and place a lock on it. Well he forgot the lock code and after many attempts he has to login with his google credentials, but the problem is that the wifi is off so it wont fix anything. So im trying to format it for him, I can get to the recovery screen, but only the volume buttons will work and the no other button will let me confirm the selection. Dose anyone know what i can do?

1. Place the rotation lock switch in the up position
2. Press and hold the Volume down button, which is located farthest from the rotation lock
3. With the Volume down button held, press and hold the Power button for 3 seconds then release it. Continue holding the Volume down button.
4. Once the tablet vibrates, switch the rotation lock on and off repeatedly while still holding the Volume down button.
5 Release the Volume down button and stop switching the rotation lock once the "Erasing Userdata..." message appears in the upper left corner of the screen
6. Once the factory reset has been completed your tablet will load to the Welcome screen.
7 Your Factory Data Reset has completed now follow the onscreen steps to setup your tablet.

Hard reset the tablet, you'll lose everything, but it will revert to factory condition.
Power off the tablet
Hold Volume + (the one furthest from the power button/ lock switch, right if holding landscape)
While holding Volume + press and hold the Power button
Once it turns on, holding the Volume +, release Power and wiggle the lock switch up and down a few times.
Screen will then say its formatting or resetting or whatever it says.
After this completes, it may reboot, or power off, or continue booting into android, whatever it does, just let it go into android
It should greet you with the Welcome screen for setup.
Resume playing with it.

Can I do a hard-reset once I have unlocked bootloader & installed a custom recovery? Is there a way to go back to stock recovery?

You can still hard reset yes but it only erases user data nothing else.
If you want to go back to stock use one of the update.zip methods in vaches stock rom thread. It'll go back to stock recovery. If you want just the stock recovery there's a stock recovery.IMG around somewhere I'll see if I can find it.

Mandatory Update Bricked my Phone....

So I've had the Optimus G since last night, and I noticed there was an AT&T update, but I postponed it. However, after postponing it three times, it launched the update automatically and forced me to update. The phone rebooted into the update screen, going through a firmware and software update before rebooting again. It got to the AT&T "Rethink possible" logo and stays there forever. No amount of hard resets help. I had root before the update, but I've read on here that others had root and updated just fine.... has this happened to anyone else? Do I have any other option besides going back to AT&T?
EDIT: How do I boot into recovery mode? I've read that for other LG phones you have to hold down both volume buttons while holding the power, but when I do that it just goes to the AT&T splash like usual.

Did you try holding the power button? I was able to get into download mode by pressing pwr/vol+/vol- simultaneously with usb plugged in, but I don't know if that will help your situation.

Yikes, sorry to hear that. I had no problems and kept root.
Sounds like a return if you can't get it going quickly. You shouldn't have to deal with that on a mandatory update.
Good luck!

From the manual, that I downloaded from the LG website (not sure that this helps, if you don't know what to delete):
5. Using Safe Mode and System Recovery Using Safe mode
To recover your phone when malfunctioning.
1 Turn off your phone and reboot. When you see the booting animation (Rethink Possible SM) press and hold the Volume Down Key . Your Home screen will then be displayed with the words "Safe mode" in lower left corner.
2 From the Home screen, tap the Menu Key and tap All settings > General tab > Applications.
3 Tap one of the available tabs at the top of the screen and select the application you wish to uninstall.
4 Tap Uninstall and OK to confirm.
5 After uninstalling the application, turn off and reboot your phone.

Neither of these solutions did anything, but thanks anyways.

Bummer sorry to hear that. Is the att store far away? I really don't think this has anything to do with root.

No, it's only a few miles away, but as a college student with no car it makes things a little harder. I'm not sure what happened, I'm surprised they forced me to update...

[Q] Power Button messed up

The power button on my S3 (SGH-i747) is pretty messed up. When i'm not touching it, it decides to register a press and completely messes up everything im doing on the phone. It has such frequent reboots that i can barely boot into recovery. The only way i can actually boot is by holding the phone horizontally with the power button facing down. Is there any fix to this? I'm on CM10.1.0 so would flashing back to stock decrease the sensitivity of this button? Or is it necessary to fix at the shop?
Also i have a cracked screen, so im not sure it would be accepted under the warranty even if it's unrooted.

Hardware failure, repair it or get a new phone
nothing you can do, the flex cable that connect's the button to the board is either busted or shorted

I'm having the same issue.
There's absolutely nothing I can do? I thought maybe if I'd open up the device and tinker with it... maybe I can get it working.

Yes this is quite an annoying problem. If you're having the same problem, are you able to boot into download mode? I can't for some reason.

Something like this you don't want to boot into download mode. What if it resets while you're pushing a file? then your whole phone will be messed up.
I got mine to boot. My method is a bit unorthodox though.... i kept pressing the power button throughout the boot process up until the lock screen. Once it finally loads... i flicked the power button a few times really hard.... it seems to stay in the position but remains extremely sensitive.. as in, i dont even have to press it to turn off the screen.
sucks man... i think this is happening to a lot of power users. I'm literally one week past my warranty.

Yeah i didnt want anything to happen while anything is installing etc. I somehow got into recovery, but it shut down within a second. (thankfully the first option in cwm is reboot, so that saved me). I can't return for warranty because I'm rooted on CM10.1.0, which was why i wanted to attempt unrooting (but that seems impossible at the moment).
http://forum.xda-developers.com/showthread.php?t=1753574
That thread seems to be the solution to our problem, but i feel that if i open it up, something worse will happen. Right now, the phone boots up fine when held horizontally (but shuts down ~2min later) and i can easily backup my data.
One strange thing that i've noticed with this problem that maybe isn't right. Normally , do you have to hold down the power button to shut it off? I always used to think that a power menu would show, THEN you could select shut down, but here, it just shuts down. The power menu flashes sometimes, but shuts down anyway. This may also have me believe that something other than the power button is the problem.

if you hold the power button for 5 seconds or more , it will skip that power menu and reboot. So this still sounds like power button to me.
thanks for the link, been searching everywhere... so fckin hard to search all the S3 threads on XDA. They need to consolidate

Were you able to fix your problem with the fix in that link? I seem to be having the same problem as you.

No, I ended up buying a new phone (I was going to upgrade anyway). I took out the power button, but that wasn't the problem. In a way, it was the button under the button that was sensitive. I would have to take out the motherboard to see the exact problem.

[Q] Rooted Kindle Fire Stuck

Howdy!
It was literally AGES ago that I rooted my Kindle.
It's been totally fine forever! Then last night it needed charged so I plugged it in and went to bed. When I got up in the morning the power button was lit a nice shade of green, showing it was charged....
So later in the day I went to turn it on... nothing.... So I held the button to reset it.... After a bit I pressed the button...
The Blue KindleFire screen came up (with the statement at the bottom to "Press power button for boot menu...)
I didn't press anything, but it acts like I did and soon I see the three choices of "Normal Boot, Recovery, Reset Boot Mode" and the lines on each end move from choice to choice over and over....
That's all it does! I can press the power button and it doesn't do a thing. It just keeps scrolling.... If I hold the power button, it'll shut off after awhile.... but when trying to boot it again, it goes right back to that boot menu, scrolling through my choices and that's it. I have yet to find a way out of that.
I've tried plugging it into the charge to see if for some reason it's a power issue, but it does the same thing. I've tried plugging it into the PC via USB cable and it does the same thing!
Anyone have any suggestions or pointers? I'm kinda lost at this point, I've never had an issue that I couldn't recover it from until now, and I've had this thing for a good number of years.

Sounds like a hardware issue, specifically the power button is sticking. Try using an object see if the button is physically depressed. If not, then it us the switch inside.

I can press the button though. I can press and Hold it to reset it, and I can press it to get it to go on again.
I guess that is possible, but if it was intermittent, the times I've just pressed the button repeatedly to try to get it to do something should have gotten me past that scrolling boot menu.

Thing is, the reason it is scrolling is from an input from the button. If the button is not the issue, then it is a circuit problem. Bad news. Better to have been the button.

Can it boot into reecovery?

Sadly no, the PC will not see it. It doesn't get far enough to be seen.
I did find a little more info. I used the Kindle Fire Utility 0.9.6 and it's running FFF 1.4a I believe? (bootup screen with the Blue Kingle Fire Logo).
The weird thing is, if I have the USB cable plugged into it and hit the power button, it won't come at all. I have to unplug it in order to get the boot sequence to come up.
If I remember correctly the boot options menu always scrolled, you just pressed the button when it was on the choice you wanted.
I did launch the KF Utility but when trying to do anything it just saying waiting for device because it isn't seeing the darn thing...
I really hope I'm not screwed. What really sucks was I had JUST been thinking about running the clean system image to restore it in TWRP but it did this before I decided to go ahead and do that.

My menus only scrolled if I press the power button. Otherwise, it boots whatever the menu is on. That is why I suspect the boot program is receiving an input from the button.

Well... I'm reading elsewhere the same thing you said.... yet mine has ALWAYS scrolled since I first loaded it and only advanced when I pressed the button when it was on the choice.....
Perhaps my power button has been having an issue for far longer than I realized... yet when the system did boot it didn't act like it was being pressed constantly.
Such a confusing issue.... sadly it's looking more and more like I've just got a Kindle I can do nothing more with

[Q] Sumsung Galaxy Tab S 10.5 (SM-T805) screen went black

My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn’t drop and hit by anything…i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life

Are you able to get into download or recovery? I've never heard of something like this before. Maybe go ahead and let it die and then plug it back in and see if you can get into download mode by holding home+power+volume down then re flash your stock firmware or whatever you were using. Or do home+power+volume up to get into recovery. If you still have stock recovery then you can just do a factory reset right from that but if your using something TWRP then your still going to need to flash something after wiping your data.
Not sure how else you can get it to shut off since you can't see it. Even knowing where the power menu is once you press the button it would still be tough to hit the right thing. I'd say let it die. Maybe someone else can come shed some light. Of course it could be a hardware problem as well. I'm leaning toward software still though.
If your still completely stock I'd say let it die and get into stock recovery. Home+power+volume up and then wipe data and do a factory reset. Now if the screen stays black after its off and you've plugged in the charging cable then I'd imagine there's a more a serious problem going on.

Yes I am waiting for battery to be completely drained out. I will try your method once the battery is completely dead.
thanks

Your welcome let me know how it goes. Will do my best to help.

I don't have my tab with me right now but can't you hold power button for 10 sec to force a reboot? All Android device I ever had could do that.

Doest work on t805 holding powerbutton, just hold the buttons for download mode and that will force it to reset and prompt you to press volume down to cancel volume up to continue...hold for 30 seconds, and if nothing appears let go and just press volume up once, still no joy then pop back cover off and unclip and reclip battery if your brave, thats what i did before i new about this quicker way.

How to run the battery completely down..? its still active and on... though not showing anything on screen.
Is there any quicker way... ?

To do a hard-reset on these Samsung devices, you need to hold Power + Home + Volume Down until it reboots. On every other device it's just Power. Some it's Power+Home. For some reason Samsung likes to be different.
Or if you have previously enabled USB Debugging, you can plug it in to your computer and do an ADB Reboot.

Power + volume down + volume up works for me as reset.
