Hello Nexans,
Long story short:
I was applying SGP's flex to my phone yesterday. Too much water maybe, my phone started acting weird after installation, really dimmed display, touch screen not registering touch, and etc.
So I opened up the phone per ifixit's instruction, attempting to see if there's really any water in there so I can dry the components up.
At the time of opening it up, didn't notice any water at all, while the screen still remains not responding. At the end, the phone finally failed to boot (white Google screen looping). So I put everything back on, and finally leave it looping on my desk while I went out trying to have some fun in order to blow away this Saturday night sadness.
Magically, when I returned home after ~5 hrs, the phone is in the system and the touch screen works perfectly again. Also, the screen is showing images normally again. I happily went to bed with my phone.
This [sad] morning, volume button won't work. Opened it up, found that the volume switch (which was soldered onto the mobo) was ripped off (probably by careless me). Refer to this pic here. EDIT: sorry I still can't post outside link.
Here's the image: guide-images.ifixit.net/igi/2k6S4vvKPZh2IsB2.huge
Now I'm left alone: the phone is a imported GSM, seemingly not supported by anyone in the U.S. right now. Moreover, since the volume switch is soldered onto the mobo, and I am very sure I will ruin the phone if I try to re-solder the switch onto the mobo (it's some finest soldering on there), not to mention that the Cable Ribbon of the volume switch seems to be ruined as well, I think my only option is to get a totally new mobo that has volume switch soldered onto it.
To summarize:
1.Do I need a new mobo, if I find no one to help me repair the phone?
2.Where can I get a new mobo? (searched on eBay w/o results)
3.Will changing the mobo affect anything? I assume the data and system would be lost, but how about the identity of my phone?
4.If there's one agent in the U.S. that you think would take care of this uncostly (~$100?), who would you refer? Maybe Verizon, Samsung, or someone else?
5.If all of the above attempts fail at the end, I'll be considering selling it at a deep discount to someone who's got his way of restoring this phone, where would you recommend for me to go find such a talented Nexus lover? Will eBay fulfill this purpose the best?
Finally, thanks for you, the fellow members, for your help in advance. I hate myself for opening up the phone, now, thinking that the phone may have recovered for good w/o being opened up by me. Now that it has recovered with a broken volume switch in its body, making this issue much more complicated
Again, thanks...
shoulda turned off the phone right after it started acting funky and put it in a bag a rice
it sounds like you jumped the gun and opened the phone prematurely. How long did you wait to open up the phone after you installed the screen guard?
As far as your situation, I would probably cut my losses, get what I can out of it on eBay and buy another one.

Should have I also shouldve stayed with a dry apply film. Being a perfectionist, I almost knew I would ruin the phone by over spraying the application solution for a easier and better application

Actually, immediately. I didn't know the gaps around the glass screen is also the entrance for the water to get into the phone. I thought only headset speaker could let some water into it. After disassembled the phone, I realized that the water can easily get into the phone thru the gap, which leads the water right onto the mobo underneath the glass... Again, I didn't notice any water inside the phone, but i could be just moisture that's playing some nasty game here. I also did some intensive swing and tossing of the phone to get water out, until there's no water coming out.
Anyhow, I just went to Verizon store, and they said they wouldn't touch anything GSM, and said the only option for me seems to contact Samsung. Or as you said, I could sell it on eBay. Don't know how much it's worth though
I had to open up my Gnex last week because i dropped it in a puddle of water while getting out of my car...
If i remember correctly, the vol rocker is glued to the internal part that comes out with the screen and most of the electronics, so i cant imagine how you would have torn it off...
Its connectected to the main pcb via a connector though, sure you didn't just unplug the connector??
You could also try to go without the volume rocker, use some kind of widget for volume control, not ideal but cheaper than a new Gnex
Ooo, I'm sorry for both of us...
Yes, the volume switch is double-side taped, but the other end (the cable ribbon itself) is soldered onto the back of the mobo in my phone. I don't know how or what force ripped it off of the mobo. The cable ribbon is torn pretty harshly... I'll upload a pic when I make past the 10 posts and "unlock all capabilities"..
Also, did you notice any "sequela" after the incident? Does your phone function good now? There's time that on my phone the touch screen does not respond/register touch anymore suddenly. I usually just leave it standby with screen off. Usually, after 1+ hr, when I turn the screen back on, the touchscreen works fine...
Driving me crazy, this bad luck.
Guys,
Here's another issue... How do I get into fastboot mode if my volume rockers don't work..?
Tried Toolkit V4.1 and it keeps saying waiting for device..

Install the app called quickboot, it lets u go direcrly into recovery or bootloader without holding volume keys.
Thank you sir, I'll give it a try!
OOPS.. I'm not rooted...so it's a no-go
Hey cswithxda, have you found a way to fix it without replacing the mobo?
I live in Brazil, a friend of mine brought one bought at Negri electronics at US for me. It suffered an accident (part of it involves someone pushing down a window over it) and the screen cracked.
I've sent it back to Negri for RMA Repair to fix the screen and they did it, but before shipping back, found that the volume buttons weren't working. They canceled the shipment and found out that the volume cable was broken (the screen crack was near to the volume buttons, so I guess it wasn't them that broke it while fixing the screen).
Well, I've actually paid for the screen repair and ship back, but they claim that their repair facility was unable to fix the volume... any light over this?

Sorry I can't help buddy, at the time I owned the device, it was still pretty new, so I couldn't find a source that actually sells GNex motherboard. I think the only way to fix a ripped rocker button is to replace mobo if you don't find anywhere to solder it for you.
Important part is this, for whoever got the chance, buy it from Amazon! The rep was kind enough to issue me an RMA after knowing my ripped volume rocker is my own fault, and while I was actually trying to ask him about where to send it to fix. They just gave me an RMA and let me send it back and get anything else I want. Amazon customer service another miracle!

Thanks for the help! altho i returned the device
My phone's volume down button appeared to be stuck. It's not physically stuck but the volume pop up would come up all the time and turn my volume all the way down and vibrate. I installed Quick Settings hoping that would override whatever was causing the issue and it seemed to do the trick except I'd still get the random vibrate from before it just wasn't turning down my volume. Then I tried turning the volume down with the volume rocker and it didn't respond. I could still turn the volume up, just not down.
I unlocked my bootloader yesterday in hopes of rooting but I never got around to actually rooting my phone. I was going to do that this morning so I pulled up cmd and threw in the command: fastboot flash recovery r1-modaco-recovery-clockwork-touch-endeavoru.img. Then I realized my phone was still on *facepalm* so I tried to power down but the power down options weren't popping up like they're supposed to. So I held the power button down to force the power down but instead of powering down, it went straight to the bootloader screen.
Now here's the problem... my volume down button still does not work and to make matters worse, my volume up button and my power button are acting as the volume down button. In other words, I can only scroll down. I'm unable to select anything or power down.
Any ideas?
After pondering for a while, I'm thinking that this is a hardware issue and the volume down button is defective. I notice that when I push either the volume up or power button, the cursor doesn't move until I let go. That leads me to believe that the volume down button is still stuck so when I push another button, the other button doesn't do anything (similar to power windows in a car where the driver is trying to roll a window up while the passenger is holding the window down button and the window just sits there) but when I let go of it, the volume down button resumes and moves the cursor down.
The worst part is, I've been in Germany for three days and I've only had the phone for two. I don't speak German (I'm a lazy military husband who figured submersion would be the best way to learn) so turning this in for warranty is going to be a major pain in the ass. *sigh*
Hi, sorry to hear you are having problems,
Since you haven't actually rooted the phone and haven't made any modifications, you should be able to return it for warranty. This would have happened even if you weren't trying to root the phone; just powering it down. So yeah... Seems like warranty is your only option I'm afraid....
Good luck
I figured the warranty should still be good. I'm just hoping I can do the warranty exchange in the store like they do in the US. If not, then I hope I can call the US customer service. If I have to go through the German customer service, it won't be fun (because I don't speak German, I'm sure they're helpful if you can communicate with them).
I was able to "unstick" the button about 30 minutes ago. I read that there's a creaking noise if you squeeze the lower corners of the phone. I squeezed the phone and sure enough, it creaked, but only slightly. Nothing to worry about. But I did see that familiar rainbow looking wave in the screen. So I squeezed all up and down the sides (to this day, the rainbow distortion of LCD screens still mesmerize me) and that inadvertently unstuck my volume down button. It has still stuck a couple of times since but it stops when I squeeze the screen near the button.
I'm still going to turn it in for warranty, but at least I can play with it until then.
Ah did you got it booting then?? I would get it to an O2 store ASAP if you bought it from your carrier. If its an unbranded phone you could try going into a German phone shop to see if they'll replace it. Most people working in German shops should speak a fair amount of english, so that won't be a problem.
EDIT: Oh and before you go numb looking for one; Germany has no O2 stores I think...
Hey,
I'm happy you were able to fix it. As for the warranty thing. Technically you void it by unlocking your bootloader, no matter whether you rooted it ore somesthing. But as this seems to be a hardware issue that can't be caused by software (like frying your CPU by overclocking it).
Welcome to Germany! Normally stores won't return it, but sometimes they offer to send it to HTC for you... If you're lucky and you bought it at "Media Markt" you should be fine though. They usually do that kinda stuff, if you got it from O2, chances are low they will just give you a new one. Sorry
Yes, I am able to boot back into the OS. There are O2 stores in Germany, that's where I bought the phone.
Thanks for the info guys, I appreciate it.

I wanted to give an update to this situation in the rare case that I'm not the only one who has experienced this problem. I ended up taking my phone back to the O2 store and they sent it off for a warranty claim. During this time, I was given a Motorola Milestone as a loaner. It was small, slow and frustrating but at least it was a Google phone. Two and a half weeks later, my phone was back. The verdict? They could not duplicate the issue and therefore did NOTHING! I was so frustrated because I felt like I went without my phone for absolutely nothing. The O2 staff did tell me that if I send the phone back to the warranty claims a second time and they don't find anything again, they will replace the phone. But did I really want to be without my phone for another 2+ weeks? After all, I did find a quick temporary fix for the issue. I decided to hold onto the phone in hopes that I could better understand the issue or even live with it.
After a few more weeks with my phone, the issue was getting more and more difficult to "fix" until eventually, it wouldn't fix. I still used the phone for a couple days until it froze up, rebooted and went straight into the bootloader where it stayed at full brightness until it died. I couldn't shut it off nor charge it. Essentially, it was bricked. I went back to the O2 store again to send it off for warranty. This time it took an agonizing 3 weeks and again, they couldn't fix it. But this time they sent me a brand new phone! Yay! So now I'm sitting here with a fully functional awesome Android phone. It was rough going 5+ weeks without my phone but I'm happy now.
Recap of key points:
- HTC One X
- Unlocked bootloader
- Rooted
- Custom ROM
- Had a hardware issue
- Sent in for warranty... twice
- Phone was replaced after second warranty attempt at no cost
hi im having a problem with my desire z keyboard. some keys such as O, P and S are not working well. like i have to press them really hard to bring the letter on the screen. the hardware touch is fine like the keys feel normal when i press them but with some 4 5 keys, the letter doesnt come up unless i press really hard. anyone else having such a problem and solutionss?
I am having the same problem, but I've kinda got used to the on-screen keyboard anyways.
Same problem here, and for another 3 people on Polish forum said about this too. I have send my DZ on warranty - waiting for answer. I have rooted ulocked and changed rom so I am curious about what they will say :> Depending on how much people have this problem it's a hidden defect for DZ not caused by user.
I have problems with my "a,s,d, and spacebar". Too bad that my Desire Z's warranty is already expired. Agree with the other poster, best way around it is to get use to the touch screen keyboard.

My DZ keyboard had been working perfect until recently.
The 'i' key and space key need to be pressed hard to register. But for the i key, sometimes if I press it hard enough, it will register twice. I think it is related to dirt/dust getting into the key or aging issue. And since my DZ is nearly two years old, I am not complaining. Anyone tried to take their phone apart and clean or replace the keyboard?
As i said before, I have send my phone to HTC Service with this problem and yesterday I got it back.
My phone was rooted and "htcdev unlocked" with Virtuous Sense ROM on board when I sended it and... there was no problem with it . They replaced "FPC Pre-Assy Qwerty" and didn't even restore orginal OS. Keyboard is working perfect.
Im having problems with my . button, no more warranty, so i guess i just have to live with it...
Have you attempted to shift to a different ROM? I had encountered certain hindrances akin to this whilst utilizing certain beta ROMs. Upgrading the ROM had solved this. Alternatively, it may be a hardware malfunction.
have the same problem as yashif,o,p,i,u need to press harder sometimes it register the key twice is it a hardware problem?

Sounds like dirty contacts in the keys. the proper way to fix this is to carefully disassemble and clean the keyboard parts with some diluted isopropyl alcohol.
The _improper_, _unsafe_ _lazy_ method that does not require disassembly but is probably a stupid thing to so (but I've done with success on another phone, not a Desire Z), is to remove the battery, spray a bunch of DILUTED rubbing alcohol onto the keyboard, saturating it so that it runs into the nooks and crannies, then repeatedly press the buttons up and down -- with the idea that some alcohol gets into the contacts and cleans them. Let the phone dry completely for 24 hours, put the battery back in and hope it turns on, then hope the keyboard works again.
Let me stress that I would only do this with a phone that is past warranty and that you wouldn't mine if it never works again...
Hey guys.
Late response but I happened across this thread when I was having this problem for a few days. I slowly realized after reinstalling my ROM with no joy, that I'd actually experienced this problem before, back when I'd taken the phone apart to replace the screen. Back then it turned out i'd left the keyboard ribbon cable loose which was causing some of the keys not to work.
Well it appears this time I may have knocked the cable out of place after dropping the phone (I do that alot) as after opening the phone, taking the cable out and then simply popping it back in, my ketyboard was back in working order!
If anyone is unsure about opening up the phone and trying, it's simply the first 3 minutes of the below video, upto removing the ribbon cable (just take it out and pop it back in, easy!)

DONT spray a bunch of DILUTED rubbing alcohol onto the keyboard
sorry for digging old threads but i had this problem and i thought someone will have it in the future

The phone is too well made it has 3 layers until u get to the contacts
and is 95% probable you hard brick your phone
Dust CANT get to the contacts, instead the problem comes from the metal part touching the contacts that is bent overtime.
these things look like a ( and when they are pressed they go like this | and in the middle of them you will see
i will make a full tutorial how to repair bad contacts on this

Hey guys,
So today my phone started acting up, the power button has become touch sensitive. As soon as I touch it or come close to it on either side of it, it acts as if I'm holding it down. I tore it apart to see if it was sick and it isn't so I can't figure out why it's doing that? Anyone ever had this same problem or have an idea of how to fix it?? Any help would be greatly appreciated.
This has become a common problem with our phones; do a search for "power button" and you'll find several threads reporting the same/similar problems. Some people seem to have managed to fix their issues by wiping the area with alcohol or re-flashing their recovery and/or ROM (I personally don't see how that could help a hardware issue, but whatever). In my case, as well as several others, the power button became permanently damaged, the phone was stuck in a vibrating bootloop and the only way to stop it was to take out the battery. I chose to have the power button replaced using the MobileTechVideos repair service. I wasn't 100% satisfied with their customer service, but the power button was replaced and my phone works fine now.
I suggest the same, I got my phone back a week ago after my power button got stuck.

I bought a replacement power button for my Sprint S2, and it looks like they now offer mail-in power button repair service too. Their feedback looks better than the experience you had.

Don't bother buying a new power button yet! I had the exact same problem, and it was throwing my T989 into a boot loop. Your most likely problem is that your power button internals are getting jammed up with dirt from your finger and lint.
Here is a thread with a person experiencing a similar problem. Here is another thread where I go into detail on how to attempt to fix your problem. You already have the know-how on how to disassemble your phone, so this should be easy for you.
HERE is the original thread that I found which addresses the problem you seem to be having.
CRC QD Electronic Cleaner saved me from having to replace the hardware and I haven't had power/boot loop problems since!
If you feel as if you don't want to over-do it with the electronic cleaner, you can give your entire logic board a nice rub-down with some Isopropyl alcohol (I got mine from a general pharmacy). You should be able to get the electronic cleaner from any auto shop, but I've had specific success with CRC QD Electronic cleaner. I don't know enough about electronics or chemistry to recommend any other brand/type, so if you can't get that specific brand, then I can't help ya!
My note 10.1 2014 seems to go to sleep randomly. I will be in the middle of doing something... typing, reading, etc... and suddenly it will just go black. It then Wales normally from the lockscreen. Has anyone encountered this before? Clean room with either bindroid or stock kernel does it. I am not sure whether the stock room did it. I think not but I can't say with total certainty.
You should try to find out if it is a software or hardware issue. It could be a power button with a loose contact or a damaged board. I for example had my 7.7 gtab turn of randomly, I opened it up and switched it on and disconnected the power button, it still rebooted randomly. Then i switched it on and disconnected the board with the powerbutton and camera while it was on and it stayed on. I knew it was hardware related because it got wet, replacing the damaged board fixed the issue. What I want to say is: By backtracing to the actual cause of the issue you will be able to narrow it down and we might be able to help.

Thanks. I have not been able to get the issue to repeat itself consistently at all yet so I have not narrowed it down. I thought there might be a known issue of some kind. Failing that I will have to keep fiddling with it until I get a sense of what if anything actually trips it.
Thanks for the reply.
Hmm, I am exploring the possibility that my case has some magnets in it that I didn't know about, and when folded over it's tripping the automatic sleep. This looks like a promising line of investigation... I know I previously saw an image showing where the magnet sensors are on this device. Can anyone point me to it? I can't feel any magnets in the case but if I know where to look I may get luckier.
