[Q] Power Button Not Working - Galaxy S II Q&A, Help & Troubleshooting

Hi everyone,
The power button of my SGS2 is not working correctly, when I pressed it, the phone is restarted instead of show the phone options (power off, reboot, profile, airplane mode, etc) What's wrong? Also I've checked/unchecked the Power button instantly lock option in Lock Screen section.
Rooted phone, with ICS 4.0.4
Thanks!

[Q] Galaxy S2 stuck at boot screen after flash custom ROM CheckROM RevoHD™ V6

Help,
My phone just stuck at the Samsung Galaxy SII GT-19100G screen..
I can't enter CWM recovery mode or Download mode as well
When I press Volume Button UP + Home + Power, it will turn off the phone and never turn back on. When I release the Volume Button Up + Home, it turned back on and stuck at the screen again.
In fact I can't even power off my phone.. When I power off it, it will auto restart and stuck at the screen again..
Anybody.. please help
I'm only taking a wild stab in the dark here but my guess is you flashed firmware for the I9100 onto your I9100G device.
Best to download firmware for the "G" model and flash via download mode. If you have a jig it might come in handy.
Looks like you have some research to do. Good luck.

Yes, lucky I manage to flash it back to the original ROM.

For reference Vol Up + Home + Power is used to start the phone into Manual Mode, not turn it off. Vol Down + Home + Power is used to start the phone into Update Mode.

NO NO NO it puts the phone to RECOVERY MODE
not turn it off. Vol Down + Home + Power is used to start the phone into Update Mode
NO NO NO It puts the phone to DOWNLOAD MODE .

Turn off the device

During start up, hold down the menu button as soon as you feel the first vibrate
Continue to hold menu down until phone has completely booted
try to turn your phone off, then take out the battery, then press the power button and hold it for couple of seconds, put the battery back on and turn it on see if it works if it doesnt then
Turn off the device

During the Xperia logo, if u keep pressing vol. Down button, u wil enter safe mode. I tried.. Happened once for me.. It ll show 'safe mode' at bottom left corner..with normal home screen

Hit thanks if I helped you
I'm also facing the same problem. Phone is stuck with safe mode. The problem is vol down button. Sometimes it registers vol down button without me pressing it. I'm running Ice Cream Pureness ROM.
when phone is in safe mode, does the menu button (the one with lines over it) work?

Power button problem

Hi. I did http://forum.xda-developers.com/showthread.php?t=1586570 this to my phone and since then every time I turn it on the black screen with AP Fastboot flash failure appears and not the Motorola logo. Not that I turn off my phone that often, but it's frustrating. I have to pres Vol Up/Down + Power button and choose Normal boot everytime I want to turn on the phone. Please explain me how to unroot or I don't know, I have the phone for 5 days now. I want it to look like I've just opened the box
P.S. Already tried Factory reset, doesn't help, still the black screen when I press the power button to turn on.
P.S.2 My system version is 651.167.3370.XT910.AmericaMovil.en.01 if it matters.
Really? The link I posted is from this forum. Come on. I should be able to undo this flash I've made and really return to fabric settings.

[Q] Help! Messed with 'Simulate Secondary Display' settings!

Hi,
I'm new to xda, I was on CM10.1 nightly build 29th Dec, and I was just checking the dev options to see what was what. When I changed
the 'Simulate Secondary Display' settings the phone just froze. It's perfectly fine, everythings there, it's just that when I boot it, it shows the boot logo and when its about to show the home screen it freezes. I know its not bricked, and I know all I have to do is change the Dev Options. Could
someone plz tell me how? I actually have important messages and pictures that I don't want to lose.
Thanks in advance

Flash a different rom like stock based custom rom and install cm10.1 again if you want to
Thankfully I had a fairly recent Titanium Backup so I only lost a small amount of data + time. I hope you manage to find a solution as you said you have important messages and all.
Wiping cache doesn't help. I'm still stuck. :crying:
--- Edited ---
My itchy hand touch that setting as well. Stuck at CM10.1 boot screen.
Solution: Just boot into recovery, wipe cache and reboot. Done and everything working as usual.
Same question
I wiped cache and davkit cache in recovery but no luck
I would like to know the function of this option

1. use Safe mode. (I just pressed all button except power button, and it booted.)
2. disable Simulate Secondary Display.
3. reboot
(side effect : all widgets will be disappeared)

wow, it works, thank u so much! and for the first time I realise that android has a safe mode just like my windows ! feel shame for my poor knowledge
I couldn't enter safe mode. Presing Vol up+ Vol down should enter safe mode?

Yes. I just found this thread because i also locked my S2 activating "second display" and looked for a way to boot up in safe mode.
1. Turn off your phone by long pressing the Power button.
2. Press Up/Down Volume buttons (yes, both) and Power button at the same time.
3. Keep pressing all 3 buttons until boot-up image appears.
4. Release Power button while still pressing volume buttons (not sure if this is mandatory, but worked on my phone)
5. Phone will boot-up with "Safe-mode" badge in the lower-left corner of your screen.
Now go to Settings-Developer options and disable Second Display. After that, just reboot and you should be fine.

confirmed dirty flash does NOT work
confirmed flash 10.1 nonofficial then re flash DOES work
anybody try a restore?? seemed to work for me except i only had an ancient one... plus the safe mode trick seems better unless you just made a backup
im on rezound infected 2.2 JB 4.2.2 by the way and safe mode didn't seem to work but i just read the part where you hold volume buttons after letting go of the power button. so that might work for rezounds still

Seems not to work on HTC Desire Z. In a 3 seconds after holding volume buttons and power button, LED lights up in green and remains in this state. Using Jelly Baby 1.5.0.
Any other way?
EDIT: I found one. Turn on the phone and when on HTC logo, hold S button on QWERTY keyboard until home screen show up.

different phone, different method. the above applies to i9100.
glad you found a way for your HTC.
I wasn't able to boot into safe mode for some reason (HTC Evo with non-stock ROM). My solution was to use adb to edit the settings sqlite database.
Here is the guide I found: blog.jbit.net/2013/01/android-settings-reset-using-adb.html

Try to ask in NeatRom thread in case no one help you... For the power menù, you have to go to "settings -> display -> godown" and you can set all the toggles in power menù..
For the lockscreen, I dont understand well your problem: if you press the power button once (1 sec) what happen?? have you tried to modify lockscreen options???
