I have a friend that has a Galaxy Tab S (SM-T700) and she generally uses the fingerprint sensor to unlock the device but the fingerprint sensor stopped working and she can't remember the password to unlock the tablet. The tablet is fully stock and I don't think she would want to have to use ODIN or anything to fix it. I'm actually starting to think she might be best to try to RMA it with Samsung since it's only a year-old tablet but:
A. Is it possible to do a factory reset on this device from stock recovery (and how would one go about doing that)?
B. Would that even fix the problem? (I don't know whether it would be KNOX equipped/if that would prevent a factory reset from removing the password protection)
google how to get into stock recovery on the t700. itll be something like soon as you power the device on itll be a 3 button combo for example press and hold home button power button and volume up button. something to that effect
turn device off.
press power, home and volume up
in recovery choose factory reset

Well Hello there, my name is poszy and i am having a very difficult experience.
So about a week ago i rooted my Acer A100 because i wanted cynogenmod, (i was running stock ICS)Long story short i bricked my tablet because CWM froze while i was wiping my tablet.
i did all of the following
1.) Rooted Tablet
2.) unlocked bootloader
3.) installed clockwork
All of these steps were done with the methods found here, Maybe it bricked because i was on Stock.
Anyways, i was lucky enough that my tablet only bricked to the point where it only looped during the android logo.
I am able to access the bootloader, but as soon as i tried to go back to ICS stock (because that was the only rom i could go back to and try to bring my tab back to life) that locked the bootloader. so now i have the stock bootloader. Everytime i try and flash a stock ICS update.zip it does not go past the android logo.
So i tried to flash the Honeycomb stock Acer_A100_1.014.08_COM_GEN1 Via stock recovery, and it all flashes well but for some reason it keeps asking me for a password.
i obtained the Acer_A100_1.014.08_COM_GEN1 from this thread http://forum.xda-developers.com/showthread.php?t=1307046
Stock Recovery seems to be working fine because when i power on my tab it loads into honeycomb but i cant get past the first screen because it keeps asking me for a password. :crying:
i have tried to do a hard reset with the pinhole but that does not do anything. Every Honeycomb stock rom i try to recover from always tells me to enter a password and every ICS rom i try to flash with the default recovery will not boot past the android logo.
on honeycomb i cannot do anything, i cant mount storage or access app drawer or anything because the pinlock dosent allow me to.
Can someone please help me and tell me what im doing wrong?
i was fortunate enough to make a nandroid of my ICS stock rom, but thats no use with a stock recovery right?
Since you flashed a stock rom, you should have a stock recovery, locked bootloader and unrooted. So you should be good to go, to just do a normal factory reset. To get rid of the pin lock.
-----------------------------
-Press and hold the Volume up button. Which is located farthest from the corner.
-While still holding the Volume up button, press and hold the Power button for 3 seconds and then immediately release it. Continue holding the Volume up button.
-The tablet will vibrate in approximately 1-2 seconds after you release the power button, once you feel or hear this vibration, slide the screen lock switch on and off repeatedly while continuing to hold the Volume up button.
-As soon as the Erasing Userdata... message appears in the upper left corner of the screen, release the Volume up button and stop sliding the screen lock switch. You should then also see the Erasing Cache... message below that as proof that your device is being wiped.
Many thanks

HOOOPLAA!!!! :highfive: thanks alot that worked perfectly! my tab is back to 3.2.1. Thanks alot!!
So my PIxel XL locked up (of course) and I had to soft reset it to come back. This time, however, the touch screen is 100% non responsive. Fingerprint is fine, other buttons are fine, but no touch screen. It happened to be in the middle of Play updates when it locked up - that may be related to the problem.
Anyway, I was going to try and reboot into safe mode,but I cant seem to get it into safe mode without a way to actually turn it off other than another reset, which just boots it again. I got it into recovery mode once but all I could do was reboot.
I;m reasonably savvy with the various tools, but since I can't unlock it I'm not sure where to go next.
And of course I absolutely need a working phone for work (and everything else in the world....) :crying:
Help?

It sounds like his phone won't power off though. How do you get to the bootloader menu when holding down the power button automatically does a soft reboot of the phone? He might need to let the battery drain so the phone actually shuts off before he can get to the bootloader menu to do a factory reset.
Literally ALL android devices can be forced to shutdown or to restart in a similar fashion to pc's. literally just hold the power button.
In the pixels case, holding the power button for 15 consecutive seconds will force the phone to reboot.
press and hold power, start counting to 15, as soon as your about to hit 15 seconds go ahead and mash down the volume down button with it. this should get you into fastboot where you can access recovery or fastboot flash a image.

This causes a full reboot on my current and previous pixel, not a soft reboot, ive used this method to save my arse many times. i hold it down, and it restarts all the way to the unlocked bootloader screen
I had a situation where as soon as the phone booted i would get all sorts of errors that prevented me from using the phone or even accessing the power menu, and this is the savior.
possibly try holding it more than 15 seconds? maybe let it cycle twice before attempting to enter fastbppt
Im looking to flash my galaxy s7 active because, for some unkown reason the os is corrupt or has a virus.
I have not downloaded anything, all i did was charge it while i slept, picked it up an hour ago and the voulme keeps going down no matter if i press the key or not, the button isnt damaged the voulme menu never leaves the top of device like some ghost hand is permently holding back on the volume dunno wtf that is. I did a factory reset, that didnt fix the issue. The phone is permmently stuck in safe mode, I have tried to enter recovery mode and it gets stuck in a boot loop or opens the light blue screen with the explaination point, the only options is download custom os or cancel. I would like your help on what software i need to fix my somehow randomly damaged device.

Your phone doesn't have a virus. The fact that you already did a factory reset has already reverted your OS back to retail apps and settings, just like how you first got it.
Given the scenarios you provided, it seems that your volume down-button is indeed "stuck" internally (for some reason). Samsung's universal safe mode trigger is to "press-hold down button while booting"--since your vol-down button is stuck, every time you boot, it will always be in safe mode.
You might want to remove the phone case if you have one installed. Then try to inspect the volume down button a bit closer. If all else fails, get a replacement/warranty or something similar (if still in scope). It could be a hardware defect that just popped up.
Goodluck

It had to have been a virus or corrupt os, I restarted into recovery and flashed it to stock and it works perfectly now with no issues, the button was not stuck internally or externally, as pressing it caused no issues as well as if the device button was stuck it should have navigated the recovery menu if it was stuck. either way after flashing it works perfectly so no it wasnt stuck, and besides i have a galaxy s7 active, trying to disassemble that thing is a nightmare
Here what i did: found a newest version of "allways on display" from apkmirror and installed on my oreo g9600 phone. It boots, but only black screen and apps edge. But nothing starts from edge. Only power button work, it brings 3 option that dont work. Hard restart works, can boot to stock recovery.
The big question is it possible some how restore system without factory reset (or flashing rom)?

boot into safe mode and see if you can go uninstall the app
Press and hold the Power button again to turn on your cell phone. Immediately press and hold both the Volume Up and Volume Down buttons on your device. Keep holding while the device boots. Once your Android device has booted, you will see the words “Safe mode” displayed at the bottom-left corner of your screen
Hi, how can I factory reset a Galaxy Tab Active 3 without the pin code? I tried rebooting it into recovery mode using the side button + volume down, but that only restarts the device. Side button + volume up + home button won't do anything. Any advice please?

Galaxy Tab Active 3 cannot get into Download/Recovery modeHello,
I have Galaxy Tab Active 3. When started it says Powered By Know. I am not sure if Know is enabled on it or not. Cannot login into it as I don't know the password. So I wanted to reset the device so I can use it as personal device.
However, when I tried to get into download/recovery mode with Power VolUp/Down these do not work. The device simply continues to normal boot mode, despite the fact I am holding Power/VolUP, Power/VolDown, Power/VolUp/Home - all combinations I tried.
Any advice how can I get it in recovery so I can wipe out everything?
