[HOWTO] Hard Reset

My touch screen stopped responding and the Acer tech had me factory reset the device. The instructions are as follows:
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.
Before it is asked, YES you will loose your data. Yes, you will loose root. The tablet will be restored to defaults.

Did this fix your touchscreen issue? I haven't experienced it yet but its good to know if it did.

Nope, I am working on the RMA now.

holy cow for this steps to hard reset T_T i remember i reset my a100 1 time, but not so complicated like that, ofcourse, all data root will be format.
But the funny issue is after hard reset, some apps i have used before which couldnt open )

[Q] acer a100 update failed?

A friend brought me a tablet at work today and told me that after he received an update the tablet's screen wouldn't unlock and the battery wouldn't charge past 12%. I got the tablet home and turned it on. it let me unlock the screen but kept going to a blank screen with "android system" in the top left corner. I press the home button and it goes to the home screen but all the icons flash on and off the screen. I tired using the hardware reset switch this did nothing. I tried a factory reset by using the volume+, power and screen lock switch. Factory reset went through okay but now when it boots up (after acer and android logos) it immediately attempts to shut down. it will stay on the shutting down screen indefinitely. to my knowledge this tablet has never been rooted.
I searched the forums but couldn't find any info, everyone had rooted then downgraded to get the updates. I do know that the tablet is under warranty still and that it could be sent in for service.
I would also like to note that before the factory reset the tablet would only let me unlock it once, then after i would reboot I was unable to unlock it again until it had set for some time. After the factory reset the tablet come to the blank screen with android system in the top left. the only function that would work was the screen rotation lock switch. after a reboot it would immediately attempt to shut down.
I would like to know if there is anything I can do so that we don't have to send the tablet off for service. I'm sure that I am overlooking something here. thanks.

It sounds pretty screwed. It seems like a bad flash, try running the ICS "leak" available in the dev section, name it update.zip then place it on your external SD card. Power on holding the volume key closest to the lock switch and report what it does next.

Any update on this? I know it's been forever, but I was just recently given an A100 that's doing the exact same thing (sitting at "Shutting Down).
I've been able to reflash via the update.zip, but with no luck.

Nevermind. I was able to fix mine with "SD_Acer_A100_1.014.08_COM_GEN1_full_user.zip" from this link:
http://www.imeiserver.org/download/index.php?dir=Flash Files /ACER/A100/
I renamned it "update.zip", held the left volume button (in landscape mode) while powering it on. The update ran, then it was stuck on the "Android" screen. I powered it off, then held the right volume button while powering it on and moving the screen lock button. After reboot, it was as if it just came out of the box.
I hope this helps someone else.

Actual it should be renamed to just "update" because the system adds the .ZIP so if you rename it update.zip it shows up as "update.zip.zip" and that won't work...

[Q] I have a black screen after trying to root my Galaxi S3 SGH- I747M

I was in the process of rooting my Samsung S3 with Odin3, everything was going well, I was following the steps from theunlokr.com .. it looked like all the processes were done but at the end the screen never came on. I keep pressing the power button still don’t turn on. I hold the 3 buttons at the same time (Vol Up+Home+Power) nothing happen.
I press the on/off button and it plays the start up ring shows the Samsung logo and then it goes black.
Can anyone help please, I hope I can fix it ASAP, need my phone for work. Can't understand what went wrong.
Need your help
Thank you!!

First mistake was using a site other than XDA to root your phone. Pull the battery and hold the power putton for about ten seconds. Put the battery back in, hold the down volume button + the home button + the power button until you feel it vibrate and then let go of the power button while holding the home and volume down buttons. It should go into download mode and ask you to confirm by pressing the up volume button. If this works then using Odin on the computer to flash back to stock rooted.

Some solid ROMs include: CNA (codenameandroid), Kyan, CM.
I used to use BlackJelly as my daily-driver, but couldn't do without the AllShareCast functionality, so I'm back to stock-rooted, until I find a ROM that both looks awesome and supports AllShareCast.

[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.

Holy crap the dude is right....just tried that myself on t805, holding all 3 buttons at same time in top left corner power,vol dwn, vol, up forces a simple reset without dwnload mode rubbish.

can not access recovery on htc one m8

What I basically need: I want to access recovery(or bootloader, I am not sure what its really called) to do a factory reset.
History of the problem: My little sister entered the pattern incorrectly too many times and now the phone is locked asking for gmail and password. Although I know it, but the phones wifi is disabled, so it says "wrong username or password" and hence I can not unlock it. I want to do a factory reset via the recovery but the phone is not going into it even though I press volume down + power(I also tried the volume up). USB debugging is off, and the device is not rooted... please help me, how can I get around this damn problem?

Power+vol down doesn't do anything (will not get you to bootloader) if the phone is on. This only works when the phone is powered off.
If power+vol up didn't go anything, it's probably because you didn't hold the buttons long enough. Hold power+vol up (and don't let go) until the screen goes dark (may take more than a minute in some conditions) meaning it is going to reboot. The moment the screen goes dark, let go of those buttons and only hold vol down. Don't let go, until the white bootloader screen appears. If you fail to get into bootloader (the phone just reboots, tried to go to OS) that means you didn't do the button combo correctly. Either you started pressing vol down too late, or let go too early. Just repeat the sequence until you get it right.

Thank you for replying
I said what you did, unfortunately it doesnt work

What doesn't work? I outlined a few steps. Need more details. The basic reboot sequence (holding power+vol up) does it reboot the phone or not?
This is hard coded into the device. It works in any condition short of a brick. It even works when the phone is powered off. The only time I've seen it fail is if your vol button or power button is broken.

ok, here is how it goes;
I turn the phone off
I press the voldown + power, the phone turns on, I release none of them, everything goes very normally, when the phone is at the lock screen, there is a messege on the display saying "to restart the phone, continue holding the power button for 3 seconds" and it counts down to 2 and then 1, it stops at 1, everything else is normal(except the home and back buttons have been flashing-turning on and off-since the start of the process). now I continue on holding both buttons until the phone autolocks, and here it goes to eternity, nothing happens form here just flashing home and back buttons..
I did the same process for volup+power. I did several times, each taking more than one minute..
and all my buttons are working, I can assure you of that..

when the phone is on at the lock screen, I have to swipe up, which takes me to a screen asking me for google username and password, and when I press the power button there, it displays the cummon box with 4 options; turn off, restart, airplane mode, and kid mode.
if I press the power button before swiping up, it displays the messege "To restart, continue holding the power button for 3 seconds" it counts down and stops at 1, just as I described before

Try picking restart. Then once the screen goes black, start holding (only) vol down. See if that gets you into bootloader.

lol. Your gratitude is enough.
Strange, I wonder why it didn't work when forcing a restart with button combo (power+ vol up). I don't think I've seen that issue you described, where the capacitive buttons are flashing.
Essentially, any time the phone reboots, if you hold vol down, it should go into bootloader. Or in the fully powered off condition, hold the vol down, and press and release power button (don't release vol down).

yeah, I read a tone about it and nothing worked. It seems my Htc is special
