[Q] My power button is faulty, Can I still root my phone - General Topics

My power button is not working properly
For example if the screen is off and I press the power button it comes on then goes of again in a second !
I want to know can i root my phone properly ? As i recall reading, you have to select options using the power button while rooting your phone ! What if the damn thing selects a wrong option and i loose me phone ?

buddy, you need to fix that thing is not that hard, since the only way to be in download mode is to use the hard buttons, or using an app, and these apps need root, so that's not what you need, i suggest to fix that button

[Q] power button problem

i have samsung SGH i780 windows mobile phone. it has a problem power button not working correctly. power button touch a bit mobile is switch off after difficult to switch on when i remove a battery and plug again mobile is switch on without pressing power button. have any solution to fix the problem.
thanks
sounds like you need to open the device and look inside, my guess is that the plastic power button is not inserted/aligned properly.
(which is why it turns off and on the way it does)
(probably due to a recent drop of your device)
you should view the wiki for your device on how to get inside to have a look.
im pretty sure this is whats wrong with your power button dude = sometimes this happens to me when putting my device back together.
(power button needs re-aligning)

Red Hook and press the green call key while pressing the power key, hard reboot confirmation screen appear, press the space bar to confirm, and then the phone restart. After the initial setting, the screen calibration (points 5 times the cross), the initial state of the mobile phone back to just brush up ROM. After loading the program, and personal information are lost, so hard before the restart must be careful to save personal information.

i do not think his device needs a hard reset.
(it is defo the alignment of the power button inside the device!)

[Q] Power Button Issue

Recently, I've been having trouble with my phones power button, as in it doesn't work. I can click it all I want and it won't do anything. However, if I ever take the battery out or if the battery dies and I put the phone on the charger it automatically boots up as if I had hit the power button. This really isn't a big deal except I would like to change the rom on it and am not sure how to do so anymore without a functioning power button. You guys have any advice on what the problem might be or how to change the rom without a functional power button?

Download an app called flashify from the market, open the app, select zip file, pick to flash either with TWRP or CWM (depended what you have installed as recovery), then hit yes to reboot.
You could install xposed module and reassign the power button to another physical hardware button and then replace that button with something like LMT launcher. Sounds convoluted but my power button stopped working and now my home button is my power button and I have LMT taking care of the home functionality. But that won't work in recovery sorry.

I had to rip my power button off from the motherboard. If I ever find a button worthy of soldering on I'll send you a link to it. Although I will probably wait until I get a new phone.
I tried using Flashify to flash a 4.4 ROM. Unfortunately, now the phone won't boot. It will get to the black screen that says Samsung SIII, stay there for a little bit and then shut off at which point it tries to turn on again since the power button must be stuck. Any ideas as to how I could fix it from my computer?

Unfortunately, not to my current knowledge. Power button fix's can be troublesome if you don't know how to put it on the motherboard properly.
Personally, I've repaired hundreds of power buttons on an S3.
Just wanted to give you guys an update. I was able to get my phone into boot mode and realized I could swipe right to make selections. I installed a couple old roms i had on the memory card but it would never get past the turn on animation. I finally just downloaded the adb sdk and used it to download a rom onto my phone using adb sideload through the terminal on my mac. I think that's what I did, basically just followed instructions on a screen. Anyways, updated to 4.4 so I'm happy.

[Q] CyanogenMod with Broken Power Button

SO I looked around and diddn't see my particular issue posted already.
My S III has a broken power button: when I gently tap the power button the phone locks, then turns back on, and then shows the power off options as it would if I held the power button down. I dissasembled the phone and tried using the hardware button itself (without the actual plastic button over it) and I had the same issues.
I am broke and really want CM on this phone. As you would expect, If I even try to get into download mode to flash CWM Recovery, the power button forces the device to restart.
I was wondering if anyone knew of a way that I could install CyanogenMod without the use of this button or maybe any other way.
All help is appreciated,
Thanks!
Edit: If it helps, I just noticed that i'm on 4.3. Is there even a way to unlock or roll back the bootloader at this point?
Thanks again.

[Q] button combination to force a shutdown

I must be searching for the wrong things. What is the button combination to force a shutdown on the Note Pro? Thanks.
eric
Press and hold:
Power only - power off
Power + vol up - recovery
Power + vol dn - download mode.
Is this what you are needing?

Those were what I was expecting. But the power+vol combinations aren't doing anything on mine. It is a Verizon LTE version, but I wouldn't think that would make a difference?
They should work . . . best way IMO is to just do a shutdown from within the OS, then while the tablet's off press and hold a vol/home combo prior to pressing and holding the power button. Once the model number splash screen appears let go of power first while holding the other two . . hold the other two for a second or so and then let go.

Ok, this is really silly, but I don't find any way from the Note Pro's OS to do a power down, other than the popup from holding the power button?
(Sorry, bit of background, this all started from a problem that my power button was only working to wake the tablet, but after that, had no effect whatsoever. After mucho playing, for no apparent reason, finally the popup menu came up, I did a restart, and it's been 100% since than. But it has left me worried how to do a shutdown if the power button isn't working. No pulling the batteries on these things.)

Correct, when booted into android OS a momentary holding of the power button will bring up the power menu one option within which will be to power off. This is typical of many android devices.
Are you sure your power button is operating normally?
I have read elsewhere of a user having issue with his power button not feeling right (less travel than anticipated without much tactile feedback when depressed indicating possible defect).
I would like to add for clarity that there is no force shutdown via hardware button, only force reboot. Holding power down for several seconds will force a full reboot. Holding it down briefly to get the power menu gets the power off option in the menu to fully turn the tablet off. If your tablet reboots after this option is chosen then something is wrong.

No, because after returning to working fine yesterday it is acting up again. Not a hardware problem - if the tablet is off, the button will always work to wake it up. But once again, it is now not being responded to when the tablet is awake - either a quick push, a long push, or in combination with the other buttons.
It seems like this is a software problem, either driver or app, since mechanically the button works every time to wake up the tablet. And, of course, I can't do a shutdown or reboot to see if that clears it, because its not responding to the power button. Can't remap the power button because no root available on the Verizon LTE model. Frustrating.

I would take it back to Verizon. IMO software shouldn't interfere with a long depress forcing a reboot. That function is fundamental. This still sounds to me like a possible hardware issue where a long press is not identified as such (intermittent connection in the button).

But a short press also doesn't work when the tablet is on, but does work when the tablet is off. But then it clears up, and always works properly for awhile.
Unfortunately, unlike phones, taking out the battery isn't an alternative option...
I dunno what to tell you. Without root I don't see how any software you have installed on the tablet would have changed anything, and without the ability to get into download mode I'm not sure there's a way for you to do a factory reset that will fix the issue (if it is indeed a software one). I hope someone else chimes in that can help. My suggestion to take it in to Verizon still stands though.
Good luck!

Custom button mapping?

Hey guy !
I am not quite sure I am in the right forum, so sorry if I am wrong in choosing this one.
I have an issue with my Nexus 5 where my power button does not work anymore. I have opened and tried to replace the button, with no real success... I was able to power it on by hand and I am wondering if there is any way to map the button (the one that are still working...) of my nexus 5 to custom actions.
Right now I have downloaded an Apps that let me use the volume down to wake up the phone. I have also changed the mapping in the keylayout file to wake the phone. But I am pretty sure if my phone dies or if I turn it off, I will not be able to turn it on. I was wondering if there is any way to map the volume button permanently to the power button, so that I can close and turn on the phone. (mimic the exact behavior of the power button) I am not yet familiar with custom roms (cyanogenmod and stuff), but I have heard that my solution might be somewhere in those custom roms. I have done quite bit of research, but only found solution to wake up the phone, not turn it on or off.
I really need your help with this one.
Thanks a lot in advance !!
No.
Remapping keys requires software
Phone off = no software running = no key remapping.
Mmh ok,
I thought there would be a way to modify something at a lower level than the OS that would allow me to do it.
Another idea then... Is it possible to send a boot message by USB to the phone ? There must be some kind of software running because when it is pugged, an image is shown with the battery charging, so is there any command I could send to boot it up ?
Thanks again !
EDIT : I found a kind of solution to my problem. It does not map the power button to the volume button, but I guess it is the same thing as sending a boot message by USB. By setting the variable oem off-mode-charge to 0 with fastboot, if the phone is powered off, it will boot it up if connected by USB. In case anyone stumble on this post...
