non-responsive home & power buttons after water spilled - Galaxy S II Q&A, Help & Troubleshooting

Hello everyone,
i need your help in a dillema. the background story started yesterday, when i washed my hand and tried to reach something over the sinc, the phone dropped from my jacket pocket to the sinc, drowning... :crying:
i took it within a second, of course completely wet.
i opened it completely, seperating the board, battery, speaker...taking everything out.
to be honest the main damage was the speaker. the entire board seem to be dry and the water sticker remained untouched.
after some rice-treatment and patient i turned it on.
the home button is non-responsive..only after some clicks it works.
the power button is another issue, where if i press it it thinks its a long press and a short time after (could be minutes) it reboots.
if i dont touch the power key it wont shut down is it has to be it.
i kinda hate the idea to change phone because i actually like it.
i dont see any other option at the moment (wouldnt want to go to larger screen size)
so i have a damaged speaker, home & power button.
the speaker is replaceable, thats for sure. after all, i could disassemble it completely.
what about the other keys? is it a possible operation? if i need to solder things that wouldnt be the case for me...i dont have proper equipment.
i saw the spare parts for couple of bucks, im just not sure whats possible and what not.
i wouldnt go to a lab because that will cost alot, and im not sure if it worth it.

O2 XDA II Broken Power Button --> Bootloader Mode

Hi all,
I have an O2 XDA II which was flashed last year to WM2003se.
Now I would like to upgrade it to WM6.1, but I cannot enter bootloader mode (using [Power Button] + [D Pad] + [Soft Reset]) because my power button is broken. This means, I also cannot do a hard reset, unless I remove the battery for a long time.
The phone otherwise is working quite well.
Is there any other way to enter bootloader mode?
Thanks in advance!
First, some advice. Several people have asked this question and it has been responded to in other threads. On forums, ALWAYS try and use the search function before asking. It might save you some time, and it also may give you further ideas or solutions to the problem. Now on to the response I gave someone else last year. Read the whole post.
IT IS POSSIBLE!
BUT DO THIS AT YOUR OWN RISK!!! I'M NOT RESPONSIBLE FOR ANY DAMAGED OR FRIED PDAs
I know because I myself have done it on an I-mate (Himalaya). It took some trial and error but I am now running WM6. In my case though, I had to completely remove the power button from the device. The previous owner dropped it on its head, and I got it for free, unfortunately most of the top is missing, including the power button.
SO, on to how I did it. I took a paper clip (metal) and put it about 1cm down, slightly to the right of where the power button used to connect to the motherboard. Make sure you have turned your XDA/IMATE on before doing this. You'll find that when you find the right area, your device will turn off, or the screen will go dark (like holding the power button for a second or giving it a quick tap).
If you manage to hold it there for the right period of time, while pressing the other bootloader buttons, then you will be able to enter bootloader.
This took me close to an hour to get just right, on both occasions I have done it, but it eventually worked.
Note: I have no idea how exactly this worked, but it did. My IMATE was useless without me updating the rom, so I had no worry about frying it if I did something wrong, that is why I was OK with playing around with its insides. BEWARE that you MAY DO DAMAGE to the device.
Good luck.
Hi my power button is broken too.
I'd love to upgrade to WM6 but can't get into bootloader mode...the paper clip approach sounds risky!
Is there an application that can get me to bootloader mode? I've searched but come up with nothing.
Any ideas?
I tried everything before doing the paperclip trick, it was the last straw for me. I did a pretty intensive investigation to other possibilities but couldn't find one.
Maybe you can find something that was a similar shape to your power button? It is a long shot but it may work. If the power button isn;t completely broken off you may still be able to use it.
Thanks Jadel.
Naaa the button has completely come off.. on its side..facing the front of the XDA. Interesting to see that other people have damaged the power button.
I might give it (the paper clip approach) a go and see how it goes.
Thanks,
Taz

Same power button problem here... I found this thread and it inspired me to another idea that works very well. I disassembled the unit according to instructions I found here in other threads. I found my button was broken off from the motherboard completely and in addition it was mechanically so damaged that is was unusable for resoldering. I disassembled the (very small) switch under a microscope and it is basically a small round steel disc that works as a spring. It "clicks" when you push the center of the disk. In the center of the switch is a contact point so when the disc is pushed it makes contact and when released it clicks back. (works like the clicking frog we used to play with as a kid). It solders onto the motherboard using 4 solder pads. The two top pads are both connected to the ground plane of the motherboard. The bottom ones are 2 separate contact islands and are not connected to each to each other. (infinite resistance between them). I soldered 3 wires onto the pads, one ground and both lower unknown contact pads. Brouhgt the wires out through the broken button hole in the cover and YES, it works like a charm. If I connect the ground wire to the lower right pad it switches on and off and I can also hard reset the unit. I have not found out what the function is of the other (left lower pad) connected to ground. Maybe it has to do with holding the button longer then a second to switch backlight on and off. In my case I cannot find any functionality. I can now manually short the wires or I can solder a small microswitch to the wires and flash my original QTEK 2020 to WM 6.1. I am going to try that this week end. Anyway no unreliable fumbling with a paper clip.

At&t 8525 will not power on with the power button

The power button has been a little fussy...requiring a hard press to power up but it had been until today. Button does not give a tactile "click" when pressed. Out of warranty. Opened it up...the microswitch isn't "clicking" Used a needle to jump the switch and it is now powered up but would like to know
1. is it fixable? (I don't solder and haven't a clue on where to get the microswitch)
2. Does the main board have to be replaced to fix it? Where can it be ordered?
3. Does anyone know of a reliable place that can either fix the switch or replace the board? I'm not going to deal w/ At&t; this was a replacement for the white screen of death and until today; it's been perfect. Everything else is working, perfect screen, case, keyboard. Battery stays charged for 12+ hours even w/ bluetooth running for over 18 months.
You cold look on ebay for a "broken" Hermes. I got a couple and found there wasn't anything wrong with them.
I don't know where you might be able to get a microswitch from but it will require soldering to fix. Unfortunately the Hermes motherboard is multilayered and this may mean fixing yourself may not work. Taking it to someone WILL cost $$$ so be sure to try and pin them with a quote for parts and labour before they "attempt" to fix it.
Good luck...
Power button screwed ..any HELP!!
Hi Friends,
I screwed my HTC Hermes power button while trying to fix its earlier problem.
Now to turn the backlight on ..i changed the settings and I can now use any button to bring it out of Sleep mode....
I used a program available on this site to enter bootloader.
However, the problem remains when "power button" is to be pressed.
Any advice on how to get over the "Press power button" to start the ROM flashing....
I found the part on celluardr.com for 32.00 which I think is a little expensive! They may be able to change it but that will cost $$. A possible solution is to clean the switch with an electronic cleaner solution that evaporates very quickly. I suggest you remove the battery with the case open to expose the switch - really mean remove the back casing to expose the motherboard and with the tube attached to the spray can squirt in the solution. Press the switch in before the solution dries - you may have some crap that got in there and is sticking up the switch mechanism. Dirt will do this.
QUESTION: What program/changes did you make to change the phone's ability to recover from sleep mode? I'd like to preserve the power button on mine and use another key that can be replaced without changing the motherboard - Ie the front phone buttons.

Hi stim141,
Thanks for your suggestions.. i shall give it a try and let you know the progress (if any)
ANSWER: From Start-> Settings-> System-> Key lock
Change the settings here to see that NO buttons are locked when in STANDBY/ SLEEP mode - when backlight turns off.
This will help to bring the device out of standby/ sleep mode.
You can have the device lock enabled so that when in sleep mode no functions are activated if any button is pressed accidentally. when any key is pressed ...it just shows you the UNLOCK option.
Also, I read somewhere, sliding out the keyboard slightly also wakes the device.

[Q] VZW TP touch screen not working

so, i just got this phone about a week ago, and its already seen several near death experiences with all the flashing ive been doing. but this one takes the cake. all i did was put the phone in my back pocket, with the screen facing in, sat down for half a second, and when i took it out, the screen had been pressed so hard that the top layer of the resistive screen was stuck to the bottm, and not registering anything. i knew the first step to fixing it was getting it unstuck. but it still wounldnt work. did a hard reset. and now im stuck at my initial tap screen to set up phone screen, and i cant do anything. this is clearly a hardware problem. can anyone help me out?
lemme be the first to say it man, ouch lol
sorry about your screen, i fear the only way to fix would be to find another screen assembly, if you search the threads for the cdma raphael(herman) i beleive there is a detailed teardown of the phone that may or may not help you resolve your problem. here is a quick link to something along the lines of what your looking for but not really too detailed : http://www.ifixit.com/Teardown/HTC-Touch-Pro/787/1
ive done that, but usually break the screen completely. i have an extra us cellular tp that has a bad keyboard and front panel buttons but screen and touch works. i just use it as a extra battery charger. has some scratches, but works. ill send it to you if you send me your old one. the screen has a double-stick tape that holds it to the frame around the edges. let me know if your able to tear it down and think you can put it back together again. its a pretty straight forward process though.
Apply packing tape to the screen and pull as hard as you can.

White Lines across my smart phone screen

One morning I woke up and the bottom half of my Samsung galaxy avant (SM-G386T) had a grid of white lines going across it. First time I restarted my phone it went away.
But they keep coming back and now it's more permanent, Sometimes it goes away briefly but they come back. I tried factory resetting. That worked the first time for a few hours but then it came back. and I tried it again and 2nd time there white lines where there during the factory reset.
The lines even show when I turn the phone off and charge the phone. So I believe this means it is w hardware issue
I tried taking the back planel of the phone off. I disconnected and reconnected the lcd connector latch on the left side. But the problem still persists. I haven't pulled up the screen with a suction cup. So Idk if there is a cable that could be loose on the front end or not. But Idk want to go buy suctions cup if I dont need to you.
Should note that I do have a good sturdy rubber case on my phone. but it has hit the floor a few good times.
One other thing that seems to aggravate or sometimes even make the lines go away is putting my phone to sleep and waking it up repeatedly or adjusting my brightness to max.
What do you guys think? is this fixable or do I need to replace the lcd screen.
man its simple
just press the wires of display which are providing it power & ur problem will be gone.
Its due to lack of sufficient current to display!!

What wires are you speaking of exactly. cause like I said I have taken the back off and disconnected and reconnected the LCD flex cable but nothing changed. Are there wires behind the LCD I need to get to? which means I need to removed the screen with a suction cup?

Does power button wear out?

The button seems very fragile on this device. On my other phones I am in the habit to click the power button to turn off the screen. But has anybody had their button "wear out" and need to be replaced?
Maybe I would be better off to double tap the screen to turn off the screen?
I've had mine for almost 2 years now and always turn the screen on/off via power button ... zero issues here, it still works as it did on day 1
Yeah me neither is working fine for almost 2years
Thanks guys, I was afraid it might be fragile since it jiggles. I just read a forum with people that bought refurb lg g5 and sent it back for rma to the ebay seller because the power button "jiggled around" and they thought the phone must be fooked up and sent it back for a refund
Yes it does. Dirt collects behind it and the button feature fails. Sensor still works.
You will need to buy a phone repair kit, and a button to replace it. All you need is a blowdryer to reheat the plate that keeps it in place, and remove it. Consider buying a new plate for it as you could damage it taking it off.
