[hack] broken power button "fix" - remap genius - myTouch 4G Q&A, Help & Troubleshooting

UPDATE: This remapping allows the Genius button to "act" like the power on button while your phone is on. Having trouble getting it to actually turn the phone on. Any thoughts?
Dead or dying power button on you MT4G? Mine was dying suddenly and i didn't want the hassle and risk a warranty exchange and get a phone with a bad eMMC chip or screen. Also didn't want to pay $100 to get the power button replaced.
Using the guide found below, I just remapped my Genius/search button in hopes it will become a power button (UPDATE: as of right now, it can only act to shut off the screen and to power down the phone--powering on the phone via the remapped button doesn't work yet.)

The only difference: by key 183, replace FUNC_4 with POWER (all caps).

like when you press the genius button, it turns the actual phone on/off...or just the screen on/off? if it turns the phone itself on/off, thats pretty cool as my power button was getting a bit unresponsive also. you could also use the trackpad to wake up the device(not sure if all roms have this feature tho). but either way Ive never thought of this little mod, reps to you

I've tried remapping Genius and Camera (I know, potentially lose a factory reset option), NEITHER of these will act to power on the phone. They'll power it down and shut the screen off, but they won't wake up an off phone.
Could it be that the power button is the only button capable of turning the phone on (based on hardware wiring and $hit?).
I've tried swapping Genius and Home buttons...they work perfectly EXCEPT for as a way to power the phone on.
I've also read that you can power up the phone by plugging it in and holding down the home button. That doesn't seem to work for me.
There must be some other code that would make this work...

Thank you for this. With the TPU case holding the power button to power off the phone is a little strange. Cant tell if im pressing the button too hard or not. I do not want to press it harder than I need to cause I know how fragile they can be. Now I dont have to worry about it!

Getting a replacement
The remapping POWER is surely helpful to some...and prevents wear on the pitiful power button.
But with no clear, definitive way to turn my phone on, should the power button completely die (which seems like it will this weekend...it's worse each time), I'd be f*cked.
I did the web customer chat with T-Mobile to get a replacement. They offered me a Samsung Galaxy S. I declined that, saying I want a MT4G or better. They responded that the MT4G is out of stock and they don't know when, if ever, if will be available. This waste of time was about an hour.
So I CALLED customer service, explained the situation, the rep looked in their systems and talked with a manager and said they have *limited* stock of MT4G. My guess is that when something is *limited* they can't give it out as an exchange. Anyhow, this rep put in the order, making sure they had the MT4G in stock, and wondered why the web chat people said they were on back order. This CS experience took about 15 minutes.
Should have a replacement MT4G next week--hopefully good screen, good chip and good power button.
This is only my second exchange.

ANY changes to the power button behavior in the ROM are in effect only when the ROM is up and running.
You can't do ANYTHING to make the phone turn on using another button when it's off, without reworking the HW.

Power button stuck on... battery dieing always.

My wing is getting extreamly annoying. The power button is stuck on, so the screen is always on and i cant turn the screen off. So my battery lasts a few hours! is it possible to remap the button to another button on the side of the phone? or at least turn off the button, so i can save battery. I searched up and down for a power button fix and i cant find one for my situation. Any Suggestions?
I don't think you can remap the power button. I think it's a hardware problem so you need to take apart the case or bring it to T-Mobile.
take the case apart and clean the button . parts are very small and delicate so I suggest allowing plenty of time to operate and be patient

[Q] Power button during calls

I read a lot of reviews about the Omnia 7 before buying one (can't have it until Christmas - I'm being good you see!) and a lot of them complained about the power button being in a place you're likely to press during a call.
My question: what happens if you press the power button during a call? On my HD (WinMo 6.5), it just goes in and out of standby but the call stays connected (so you can turn the screen on to use the keypad or switch to loudspeaker, etc). Is it the same with WP7?
My question too cause im looking to buy this phone also
I use the Omnia 7 for about 2 weeks now. Never had the problem of hitting the power button while making calls. But if I do so, nothing happens, it just turns of the screen, the call is still on. Same thing as you put your phone near your head and the sensor turns your screen off.
On other hand i "had" little problems with the back and search buttons. You can easily hit those buttons while doing other stuff. But its not as a big deal as it sounds.
Thanks very much - just what I needed. I was a bit worried as the Engadget review went on and on about the power button being just by your thumb, but it doesn't seem a big deal to me.
Edit: I thanked _ivo_ as well by accident - didn't mean it! No hard feelings

This almost put me off too. They must hold their phone in the most unusual way known to man, because my thumb sits nicely between the power & camera buttons...
The power button needs to be firmly pressed to turn off power, it would be very hard to press this unintentionally unless you hold your phone as tight as possible while calling.

Focus is dying, what could it be?

i suspect the power/lock button is FUBAR, but there are some other symptoms that do not resemble just a bad power/lock button. here are the symptoms that indicate it is the power/lock button:
1. when the phone is off, almost impossible to turn on. sometimes have to press and hold power button 10-12 times before it will shut on
2. when the phone is on and i press the lock button to lock the phone, most of the time it thinks i held the button and says "slide down to power off" although sometimes it doesn't respond at all. it almost NEVER locks when i press it (like it should be doing)
3. when the phone is on and i press the lock button to unlock the phone, most of the time it shuts off completely and i go back to step 1
symptom that indicates another problem not related to power/lock button:
1. if the phone is off and i press the power button, when the phone responds it will sometimes say "samsung" like it is turning on, and then nothing else will happen. i won't get the ATT screen and it won't boot up. this some times happens multiple times before the phone finally boots
currently i've been letting the phone time out automatically instead of the lock button, and using the camera button to unlock it. i've also been trying to not let it turn off at all, because getting it back on is really tough.
is there anyway i can disable the lock/power button...and/or is there an alternative way to lock and turn on your phone that doesn't require the use of that button? even if i tell myself not to use it, there are still times in your pocket where the darn thing gets pressed. for me that could mean it kills my phone and doesn't restart for the rest of the day, which i'm sure you can imagine is not ideal.

You seem to have a (hardware) problem with the power button (obviously).
There are a couple of ways to turn on the phone/display without the power button:
- camera/back
- connect power charger
- usb connect
Last 2 are not practical and first you already do. You should try and see how much would it cost to replace the power button, if you're out of warranty. Should be cheap, and beats workarounds.
is there any way to lock it rather than letting it just time out? what about turning it on?
do you feel pretty confident that the seemingly unrelated symptom where the "samsung" screen comes up and then shuts off while trying to turn the phone on STILL indicates the button is broken? just worried this problem extends further than just the button.
thanks for your help.

There's no other way to turn it on (except plugging it to charge) and you found the one workaround, with the camera.
I am *very* sure that the power button is the culprit in your case, most likely the spring that pops back the button is either broken or out of place.
If you keep the power button pressed, in 2 seconds you'll see the slide message, but if you keep it pressed, then it just turns off after 2 more seconds. So, yes, it's the power button and nothing else, in your case.
Fix that and you should be back to normal.
And you're not the only one with this problem. Recently, I've tried to help someone else here, with the same problem, as you can see here.
thanks. i called around and a guy here in town said it will take him 30 minutes for $30 to fix it. i'm taking it to him at lunch, so hopefully i'll come back with a fully functional phone--he also was pretty certain it was the power button, and had seen this before. thanks for your help.
well it wasn't the power button. apparently there is a battery connected to the power button that is dying. but you can't even order a new battery, so pretty much once it's dead, it's dead for good and you have to do the camera button workaround like i was doing.
though he did solder the battery to the board a little more (that's another problem, from the factory it is soldered to the main board so even if you could replace it, you'd likely damage the board), and it seemed to fix the problem. he claimed it would only be temporary and within a few weeks the problem will likely come back.

That is weird indeed. I don't think I ever heard of another type of battery being used in phones, tied to buttons. Unless it's a capacitor but anyways...
Thanks for sharing the info with us!
I know this is thread is almost a year old, but unfortunately, it seems my Samsung Focus (v1.3) also has the exact same issue.
The worst bit is that every other aspect of this once glorious phone still works and I was very happy using it, not really feeling the need to upgrade.
I was using a custom ROM which I flashed back to AT&T original 7004 but that did not work. It doesn't seem to be a software issue at all.
The symptoms are the same - tapping the power button to lock the phone gives you the option to slide to power-off and after a second it will do that anyway (without any interaction). When you try to boot, it won't progress past the SAMSUNG screen and in the rare chance it does boot, it will work for an hour or two before dying again. Connecting power helps a little (as you can't turn off the phone with mains power connected), but only just. I have tried using the original battery which I initially suspected was causing issues but even a generic battery has the same issues. I'm tempted to spend $20 on a genuine battery but I don't think it will really help given the generic battery did work properly when the phone was itself.
I'm now faced with upgrading to the Lumia 920 but with new models around the corner I think I'm going for the budget Lumia 520 which has similar specs to the Focus (except LED flash) and will hold out for the new flagship model, or buy the 920 when it falls a bit more.
Hi - just wanted to add my experience with this issue (as my focus exhibited these exact symptoms today). Unlike some people, though, even if my phone managed to boot up, it would shut down again after a few seconds on the tile screen.
Like cysser0, I also suspected the battery at first, but replacing the long-life I had purchased last year with the original battery (which I keep charged as a back-up) had no effect on the symptoms. To be brief, I tried all sorts of things over the course of an hour. Nearing the end of my tether, and resigning myself to try a format as a last resort, I discovered that if I held the power button and the volume button down, I could get the phone to stay on. Releasing either of these buttons would result in the phone switching off suddenly.
Wrapping a rubber band tightly around the top of the phone has allowed me to continue using the phone for the moment, and I have managed to do a backup of all my content (not that I will be able to restore it on this phone, it seems).

HTC HD2 broken

Hi,
After a night in a tent my HTC HD2 started to malfunction. When turning on the device I noticed it said ''safe mode'' (Android NAND (sensation rom)). At first I didn't think much of it, because I thought the device had turned of due to a dead battery. However after leaving it for a while to recharge I noticed that after each reboot it would return to safe mode. Then I noticed that the device kept showing that it was in vibration mode --> the volume down button is stuck(not physically though). Also the device kept popping up ''recent activities''... I'm under the impression that this is due to a malfunctioning call button, not a 100% sure though.
After I reflashed it to wm 6.5 the problem still prevails. However I was able to get a more detailed view of the issue:
The windows button lacks every response, the call button does not respond on touch but seems to randomely activate the call function. The home button functions poorly. However the back button, power on button and volume up button function correctly.
The volume down button seems dependent on the other buttons. When pushing one of the buttons below the screen the volume down button is activated and is stuck untill the screen is turned on and off. However the volume up button does not yield such a result. The volume down button still is responsive to touch though, as long as it is not stuck.
Any ideas how to solve this problem, or how to work around it? As a precaution I put the HD2 in a box with a moisture absorber.
Hi. I wish I could give you a better understand that what I can offer but what I think happened is you probably rolled onto your phone while sleeping.
This is not to say your problem could have came from something else but let me explain a little about safe mode.
Safe mode anyone can enter by pressing volume down and holding it while it boots up. It allows the developer a safe mode they can enter similiar to
why your computer has it installed on it. Normally pulling the battery and letting the phone reboot clears this out though. With that being said i think what
has happened is the volume button has stopped working as it should. There are several sites you can go to here on the web to send your phone out
to have it looked at and fixed. All in all it shouldn't be that costly and if your mechanically inclined and (careful) it shouldn't be to hard to do it yourself. I
would make sure you take very good notes/pictures in dismantling your phone because if you put it back together wrong you can make the problem worse.
Ebay, listing found here has the volume button and the tools necessary to open your phone and repair the volume key for around $7 usd.
Please make sure your phone model is supported and you have the know how to do this without making things a bigger issue. I would also
suggest to wait for more info because I could be wrong as well.
Thanks for your time, effort and information.
However I don't think it is a problem caused due to physical damage to the volume button. In addition the phone was in a 'sidepocket' of the tent, making it virtually impossible to roll onto it. Because the call button is malfunctioning as well I can imagine it being motherboard related, addmittedly I am not much of an electrician .
The issue has been partly resolved. Only one problem still exists. When I push the windows button it results in a volume up response. I performed a hard reset but the problem still persists, any ideas what could cause this?
Cheers
The hd2 high level of integration can not fall. Even without the screen broke, other things will break, so the sets of sets of silicone can not throw. Screen indeed not easy to break unless it fell out just in time to have something to knock to the screen.

Home button broken & Phone keeps restarting

I've tried
http://forum.xda-developers.com/oneplus-2/general/guide-oneplus-2-home-button-dead-t3324321
none of the solutions worked while I was on Seraphs CM13.
There wasn't any on-screen buttons even in the buttons menu, so then I decided to flash Oxygen back on it because I know there was on screen buttons. After getting Oxygen 2.2.1 back, I tried to call *#808# and it would just lag and nothing would show up. Now the phone keeps restarting on it's own, power button doesn't make the clicky sound anymore however I'm able to feel when it's pressed down and I'm not sure if the power button is the cause of it. Not sure what to do from here, should I just contact OnePlus? It's been several months with my phone.
Same here
The home button on this phone is a capacitative one, it should not make any clicking sound as it's static.
Probably your home button and/or IC circuit just died for you like many others (me included). I swapped the button myself, as I'm pretty used to repairing phones myself, but that alone didn't fix the home button so it's probably the speaker IC or flex cable going up to the mainboard that's gotten fried by static electricity through the button.
