Broken power button

I have a sort of weird issue. I've got a rooted evo4g with an unlocked bootloader running alter rom. I had some issues with it a while back, so I ran fix permissions and cleared the caches through amon-ra. when I did that, all hell broke loose. my power button stopped working and the volume button took over to wake up the screen. Not only does the power button not work when booted anymore, it won't even work in recovery or in the bootloader. the volume buttons will navigate in recovery, but not in bootloader.
I would like to do a nandroid backup so I can reflash my phone and then just restore my texts, call logs, etc on a clean flash...but since I can't select any menu options in recovery I can't do a nandroid backup.
I have cwm touch for my nexus s 4g, but I don't see one for evo 4g....only standard evo. is that one the same? can I still use it on an evo4g? I know some phones are not interchangeable with recovery on variants...like nexus s, for example hs two recoveries...one for 3g, one for 4g.
also, does anyone have any idea what may have caused the buttons to go haywire like this? I've never seen anything like it. I mean, sure buttons die. All moving parts fail at some point...it's in their nature....but switching control to another hw button???? That jusy makes my head hurt to think about how it could have happened!! lol

Download smelkusmod recovery. It has touch scrolling and you can scroll, select and Deselect with the haptic buttons.
Your power button issue could be a hardware failure. Possibly one of the connectors came undone rendering the power button useless.

even though death by soap has twice as many posts but the same number of thanks as you, he is right on about this.
smelkus is a great recovery and is, essentially, touch screen. what do you do if your phone turns completely off, and are you a little familar with adb?

hmmm...good question. It's actually my sister's phone. I'm also interested in knowing how she turns it back on...I'll definitely ask her that. when I turned it off I had to pull the battery and I quickly re-inserted it so it would trigger a start-up, but I'm not sure about how she turns it on if it's been off for a while.
...and yes, I'm novice-level with adb. I know adb, fastboot, etc...enough to get by, at least I have a black belt in google-fu, too...so anything I don't understand google teaches me lol
(btw, my thank you's came from the ns4g section. I posted the first working jb rom for my device and everyone clicked thanks for it....I'm no star dev or anything to say the least )
****
I just texted her...she says it always auto boots when the battery is re-inserted as long as it has a charge. it almost sounds like the power button is just stuck in a pressed position...but wouldn't I notice that when android is booted by the power control menu always being displayed (which I can't even get to display if I do press the button)???
****
I just tested with my ns4g by holding down the power button all the way through a reboot, until after the phone FULLY booted....no power menu popped up.
what are the odds the button is just stuck in a pressed position?? anyone want to take bets? I'm gonna take it apart tonight and see if that's what it is unless someone has any other ideas.

just saw this thread. and seeing as how the phone auto-boots when the battery is put in, it does sound like the power button is stuck in the 'down' position. i recently went through a similar thing with the power button, and i opened up the phone and just put the button back in place. does the button acutally LOOK like it's depressed ( ...hehe..sorry, i dont know how else to ask that..) like..is the button not protruding out like it should? if you're down for opening the phone up (which is surprisingly easy if you have the proper little screw-drivers) then it MIGHT be an easy fix. i had never done it before, and it really was easy. you can put that black-belt to use for some easy video tutorials. but, please procede with caution.

I can't say if it looks pressed since it's not currently in front of me...I know exactly what you mean, though. The inner workings of the button get stuck, and the outer rubber piece will be sort of caved in instead of sticking out like it should.
I build gaming computers as a side-hobby. I'm sure a little disassembly won't be too difficult, as long as I'm not removing any of the guts and I can just get to it by opening the case, I should be ok....too much more and I run into issues when things are that tightly packed into a case.
(reading a tear-down tut now )

Awesome! It should be a piece of cake for you, especially with your video game background. Cool. Let me know how it goes.

[Q] HTC Desire 'down' button problem.. ideas?

Hello people
Not sure if there's a thread already started on this (i apologize if there is!)
I have a HTC Desire, had it for a while now but there's been this problem since i've had it (it was given to me for free), whenever i power on the device it boots STRAIGHT into hboot/fastboot (i know you'd have to hold the volume 'down' button to enter this usually). This happens without me holding the down button down, so this makes me believe that the down button is... like stuck? The volume button ISN'T pushed down physically so? It must be an error on the board surely? I can get the rom on if i hold down with GREAT pressure on the front keys?
So what i'm asking is what do any of you suggest doing? Is there a way to fix it? My dad also brought a new 'flex' board i think it's called with no success, any other ideas?
Any ideas would i'd be extremely grateful for

Does the volume button work once the Rom is booted?

No, it acts again, as if the volume is pushed down, but like i say it isn't physically pushed down - thanks for your reply!

You need to disassemble it and see if something is wrong with button itself. It may be that just button disaligned. Also try cleaning it.

Did you solve the button problem? My gf has the same phone, and the exact same problem. The phone is running in safe mod all the time now...

Agreed. Here's a good visual guide to help with the teardown: http://tjworld.net/blog/htc-desire-tear-down

Even after disassembling/cleaning the phone is still in the same condition. Any other ideas?

[Q] Root HTC desire HD without volume key

I have searched everywhere for this and cannot find an answer so I'm sorry in advance if I have missed it somewhere. I am just bought a htc desire hd off a friend with the intention of rooting it but didn't realise the volume keys were broken. I have tried to reboot it into recovery via ADB but it gets stuck on the screen with the phone and a red exclamation mark in a triangle. I have read on other posts that this happens when you go into recovery and you press power and volume up.
Obviously I cannot use volume up so is there anyway to get around this or to avoid the screen in the first place? Or is there another way to root I'm missing where I don't need the volume keys? Even if I get into recovery mode I cannot change the options without the volume buttons.
Any help is appreciated.
Thanks

I would strongly, strongly advise getting your volume keys replaced and/or fixed before attempting to root. You can get very very stuck trying to root without working volume keys.

I actually had this problem. Wanted to use aahk and I couldn't downgrade ruu because my volume up button doesn't work. I ended up pulling off the volume rocker. Then I used a screwdriver to press the button and it luckily worked. If you can do that, that could be something you could do. But be very careful when removing the rocker or you could break it. Mine broke. But I have a otter box so its all good. Also, if you're going to get a recovery, I highly recommend getting a touch recovery like twrp or 4 ext so you don't have to use the volume buttons in recovery.

Thanks for the replied. Only paid £20 for it so not massively bothered it I break it. I've tried to do that with the volume but I don't think it's the rocker thats broken I think it's the part inside and wouldn't know how to replace it! Just thought there may be some way to get around using volume keys altogether haha

Anyone got any other ideas?

check ebay and buy a replacement volume key. They are very cheap and there are videos on youtube describing how to remove and replace it.

It's not actually the key, I've pulled the inside volume chip out (the bit behind the button which gets pressed) and pressed them and it still doesn't change the volume so I think it must be some sort of problem with the chip or the wires. I don't really know what that's called to search for on ebay haha

I am in pretty much the exact same Sh*t at the moment. However I have something even more problematic, I lost the volume rocker ages ago and I am still trying to work out whether the button itself is dead or if I am simply pressing this volume chip incorrectly. :/

If you use the end of a paperclip and try and press where the rocker was you should feel a little click as you press it in meaning it should still work. I do this with one of my Desire HD's.

Thanks for the responce (Umm)

Umm I have tried many things so far and I also find that the volume up button is not pressing. I am not sure if it is pressed in or what but the volume down button does press down (clicks when you push it) but the phone never seems to register it as a button press :/

Sounds like your stuck then. pardon the pun

Well the same as i, but u could quick boot to go to recovery

BTW I have an update on my situation. The - volume button definitely works however I think the + button is dead. However I still can't seem to get the phone in recovery by pressing power and - volume button. All I see is the T-Mobile screen and then HTC logo. Any ideas people?

[Q] Power Button messed up

The power button on my S3 (SGH-i747) is pretty messed up. When i'm not touching it, it decides to register a press and completely messes up everything im doing on the phone. It has such frequent reboots that i can barely boot into recovery. The only way i can actually boot is by holding the phone horizontally with the power button facing down. Is there any fix to this? I'm on CM10.1.0 so would flashing back to stock decrease the sensitivity of this button? Or is it necessary to fix at the shop?
Also i have a cracked screen, so im not sure it would be accepted under the warranty even if it's unrooted.

Hardware failure, repair it or get a new phone
nothing you can do, the flex cable that connect's the button to the board is either busted or shorted

There's absolutely nothing I can do? I thought maybe if I'd open up the device and tinker with it... maybe I can get it working.

Yes this is quite an annoying problem. If you're having the same problem, are you able to boot into download mode? I can't for some reason.

Something like this you don't want to boot into download mode. What if it resets while you're pushing a file? then your whole phone will be messed up.
I got mine to boot. My method is a bit unorthodox though.... i kept pressing the power button throughout the boot process up until the lock screen. Once it finally loads... i flicked the power button a few times really hard.... it seems to stay in the position but remains extremely sensitive.. as in, i dont even have to press it to turn off the screen.
sucks man... i think this is happening to a lot of power users. I'm literally one week past my warranty.

Yeah i didnt want anything to happen while anything is installing etc. I somehow got into recovery, but it shut down within a second. (thankfully the first option in cwm is reboot, so that saved me). I can't return for warranty because I'm rooted on CM10.1.0, which was why i wanted to attempt unrooting (but that seems impossible at the moment).
http://forum.xda-developers.com/showthread.php?t=1753574
That thread seems to be the solution to our problem, but i feel that if i open it up, something worse will happen. Right now, the phone boots up fine when held horizontally (but shuts down ~2min later) and i can easily backup my data.
One strange thing that i've noticed with this problem that maybe isn't right. Normally , do you have to hold down the power button to shut it off? I always used to think that a power menu would show, THEN you could select shut down, but here, it just shuts down. The power menu flashes sometimes, but shuts down anyway. This may also have me believe that something other than the power button is the problem.

if you hold the power button for 5 seconds or more , it will skip that power menu and reboot. So this still sounds like power button to me.
thanks for the link, been searching everywhere... so fckin hard to search all the S3 threads on XDA. They need to consolidate

Were you able to fix your problem with the fix in that link? I seem to be having the same problem as you.

No, I ended up buying a new phone (I was going to upgrade anyway). I took out the power button, but that wasn't the problem. In a way, it was the button under the button that was sensitive. I would have to take out the motherboard to see the exact problem.

Can't start, can't access recovery or download

Okay. When I put my battery into my phone, the Samsung screen shows up. Then, it restarts, and I don't even make it to the Samsung screen before it restarts again and does the little vibrate it does when it starts. When I try to access recovery, it shows the default recovery screen for a couple of seconds, and then it goes back to what I said earlier. I don't even make it to the download mode screen AT ALL. And when I plug it into the wall, it shows the battery screen for a couple seconds, but then its just back to constant restarts. I have had my current ROM install for a long time now and I just want to flash the stock kernel to my phone. Is there any hope in me being able to get the stock kernel flashed through Odin seeing as that I can't even get to the download screen?

Sounds like a bad power button
Sent from my SGH-T989 using xda app-developers app

Would another sign of a bad power button be that before this happened, my button was SUPER touchy? Like, I would barely lay a finger on it and it would sense it.

I THINK YOU'RE RIGHT. I found a post and some of the signs are: Black screen with intermittent vibrating, unable to enter recovery before phone restarts, unable to enter download mode before restart, phone turns on when battery inserted. Looks like I need to take the phone apart. Thank you for mentioning it could be the power button.

There are a few fixes suggested in the bandaid thread. I think one of them involves banging the button with a rubber eraser. Hopefully one will work for you.

I beat the ever living sh*t out of the power button with a screw driver out of anger. Did not help.
