Phone got wet, now boots into black screen and no response

Title sums up my problem. I've got a T-Mobile Touch Pro 2 and I've got some water on it a few weeks ago. The wet seal on the battery and phone are both pink. I got a new battery and now the phone boots. It goes through the pink little T-Mobile screen, and then onto the black screen that says the phone wasn't shut off properly and this and that. It gives me the option to press the Volume-up key to do a hard reset, or press any other button to turn off or restart. The problem is that pressing volume-up, or any other key does not do anything. In fact, the only way to turn the phone off at this point, is by taking the battery out.
Can somebody please advise as to what I can do with this phone that is only 2 months old?

I believe the life/fate of your phone will depend on how quickly you acted right after the phone got wet. For instance did you immediately remove the battery and place the phone under a light or in a window where it could dry out? I even here sticking the phone in a bag of rice will help to draw out moisture. But if the phone has sat for weeks I would say it's safe to assume you phone has seen its last days. If you can take it apart and leave the individual components out to dry out and clean off any corrosion with alcohol and re-assemble. I wish I could offer better advice... Good luck it brings a tear to my eye to hear about a touch pro 2 broken down
Edit: Sorry I didnt realize you said that the screen does display. I would definitely try taking it apart and thoroughly cleaning things out and leaving it apart to dry for awhile. sending it in will get you no where (since pink water marks) and chances are HTC/T-mobile wont even send your broken phone back.

You could also try connecting the phone to your pc, and run mymobiler. When the screen goes blank, maybe you will be able to have access to your phone through the program. You could back up whatever you needed, and would tell you if the lcd went out. Just a thought. Sorry to hear about that though.

Mymobiler says that it needs activesync functional in order to work. Activesync doesn't work for me. I tried it anyway and it wouldn't detect. Is there a stock htc touch pro 2 rom out there that is in NBH format so that I could stick it on my SD card?

The very same thing happened to my Touch Pro 2 a few days ago too!
My story is different. I had never had any water damage to the phone. On the 23rd of March, I installed the Deepshining ROM. It worked fine. The next morning, I went into T-Mobile to get the new HTC HD2. I turned off the Touch Pro 2 to retreive the SIM card, and then have been using the HD2 since. I tried to turn on the Touch Pro 2 for a few nights now. It just stays at the T-Mobile Stick Together screen until the battery is dead. I tried a soft reset while it was stuck on that screen, and received the error message just like the OP.
Can someone help me too? I am really worried that the phone is bricked. I can't get a new Touch Pro 2 under warranty since I am running on a custom ROM/radio.
I'm not sure if I can blame Deepshining. None of my previous ROM installs ever failed on me, and people seem to be installing the roms just fine.

Are you trying to conquer my thread? It's nice and all that you've got the same problem, but thread hijacking is frowned upon.

Sorry, the phone is physically damaged. There's not much you can do at this point.

Just as an update. Somehow, after installing the deepshining mod and trying it after a few days, it works fine now. It became very responsive, and I was able to install the original tmo 6.1 stock rom. Everything works fine, the only problem is that some of the physical qwerty keys either don't work or draw more than the needed letter/number. The power button doesn't function to turn the screen off, which really is about the only bummer. Everything works fine. Yay.

Strip of touchscren not working

Hi guys. I know many of you have had touchscreen problems and whatnot, i searched but it seems like this one is a bit different from usual. Yesterday the phone was totally fine; i woke up this morning and it had a lot of touchscreen problems: at first it registered touches without me doing anything, but after a couple of reboots it was just unresponsive. After another reboot and some messagging, the problem reduced to a strip on the screen simply not working. The strip is located exactly where the first notification on the status bar is (like when you receive a message and you click on that notification). I have the trueancestor stats bar buttons, so that zone is a tad more down than usual. Anyway, all I did yesterday was a quick game. I think it may be the flex cable not working because of the sliding, but it happened all of a sudden, not gradually. I must say that some weeks ago I had the same "registers touches by itself" issue when typing, but a simple reboot was enough. I tried doing factory reset, but nothing so far. Also I can't use pc companion to flash everything stock back (I unlocked bootloader months ago, even though I relocked it; I dunno if it's locked or not right now), and I can't seem to find a working flashtool download link -_-. I don't think that would help much, it probably is a hardware problem, but who knows. I'm on true ancestor 1.6 LE, stock kernel.
Any help would be great, as I fear the phone will get refused in assistance because of bootloader unlocking.

Did your phone had contact with water? When my screen had contact with water it registered touches randomly.

it didn't. it has a screen protector anyway; but that's not the problem for sure. it doesn't register randomly, simply a strip doesn't work now...

Hardware problem. Could be flex cable or digitizer.

Today there were two moments it began to work again, but a few minutes after each one the problem came back. Sigh...

Mine does that when the screen is moist or my hands are too oily. Are you sure you're working in a dry environment?

mhh... exactly that? I dunno, my hands are dry and i think the screen is too; it has a quite thick screen protector (the skinomi one), so even if it got moist that shouldn't be a problem, right? I'm now living in a different town and that may have changed something, but the problem didn't show up until now, and it was sudden.
Also, I noticed that using gamekeyboard on a certain profile I had buttons placed on the strip, and pressing hardware keys mapped to those buttons actually works. This restricts the problem just to the actual finger-touch-detecting mechanism. Does anyone know anything about this?
Edit: lol I heated the phone up a bit with a hair dryer. It works now. I hope it will last and I'll not have to do this again over and over

[Q] Weird touchscreen behaviour (only works when keyboard is flipped out?)

Hi everyone,
I've had my Desire Z for little over 2 years now and two months ago (was running CM7.2 at the time) I started getting a weird issue where my touchscreen would only be responsive when the keyboard was slid out (so the opposite problem of what quite a few other people have reported where the touchscreen becomes unresponsive when the keyboard is out). The status LED would also stay off whenever the keyboard was closed, and the keyboard backlight didn't come on anymore at all. Also, I had to make sure that the keyboard was slid out during boot, if the phone booted without the keyboard out the screen would not become responsive at all until after another reboot. My earpiece speaker stopped working around the same time so I was wondering whether it was just an issue with the flex cable becoming a bit loose, but the touchscreen would consistently start working again when I flipped the keyboard out, and also the physical scroll button on the top bit would always work, so I was still hoping it would be some weird software issue.
I then upgraded to Flinny's (amazing) Andromadus ROM (build 22, complete data+dalvik wipe) after which the keyboard backlight started working again, but the rest remained pretty much the same. Since then the touchscreen issues have been getting worse, so that I sometimes have to flip the keyboard in and out again a few times, or turn the screen on or off with the power button several times before it becomes responsive again, but then it tends to work fine until I lock the screen again, with no noticeable dead spots anywhere on the screen. I've had days where it worked all day without problems (except having to flip out the keyboard, that's been a constant for the past two months), and then today I haven't been able to get the screen to do anything at all even after dozens of reboots.
I've already bought a new digitizer and am all ready to put it in (I'll have to replace the broken earpiece anyway), but was wondering whether anyone has any thoughts on whether it could still be a software issue after all, or if anyone has experienced anything similar? The thing with having to flip the keyboard out to get not only the touchscreen but also the status LED to work is just so weird and makes me doubt that it's a pure broken digitizer or lose flex cable issue, so I'm wondering whether it would be better to first try reverting to a stock ROM before taking on the messy sticky glue stuff (I should be fine but still, never done it before)?
Many thanks!

From what you describe my best guess would be the main flex cable is what needs to be replaced. Flash a touch based recovery and see if you have the issue there as well, if so its very unlikely that its anything but a hardware fault

Thanks for the heads-up, I've been playing around a bit more with software and I do manage to get the screen working again occasionally, typically after the second boot into a newly flashed ROM or restoring a backup, and only until one or two reboots later when it becomes completely unresponsive again. I've tried CM 7.2.0 as well as Flinny's Andromadus 10, and it is only complete flashing that does the trick, cache wipe or factory reset alone does nothing. The two occasions where the touchscreen worked were still limited to when the keyboard was flipped out, and it also had to be flipped out during boot, otherwise nothing would work. I've learned to navigate my way around the phone by just using the hardware navigation button, but I'll have a close look at the flex cable when I take it apart to replace the earpiece speaker tonight...

Hello,
so I took my dear phone apart yesterday to replace the broken earpiece - everything went fine but after reassembly the replacement earpiece isn't working either, which leads me to think that all those little broken bits might actually be related to some contacts being a bit lose, all in the same region. Should've thought about that earlier really since the earpiece and the LED (only works when keyboard flipped out) are both in that top region that the digitiser data presumable also has to run through before passing through the flex cable.
In any case, I also took a picture of the flex cable which is slightly bent but doesn't seem straightforwardly damaged (see attachment, that thing on the right is *not* a rip). Think it's worth trying to replace it anyway?
What was truly bizarre is that after the first boot following reassembly the touchscreen worked quite consistently for the entire evening - I thought I might've fixed a lose contact by un- and replugging the digitiser cable, but then the screen went nonreactive again at some point. I wonder if the working screen was again actually related to some software reset caused by the battery being taken out for so long? In the meantime the actual screen and trackball are still working away perfectly. Bizarre.

Just to let people know the solution to the mystery: the increasingly odd behaviour was actually caused by an initially small rip in the flex ribbon cable that got bigger and bigger - it's actually half-visible in the picture I uploaded above, only that the rip is where the cable comes out from underneath the case, and not where it's wrinkled!
Just in case it could be useful for anyone, here's the (top half of phone) components in the order in which they failed on me, which I guess corresponds to the order of the respective data lines in the ribbon cable (from the top of the phone towards the center):
environment brightness sensor (I thought that the sensor had been broken for almost a year, but as soon as I rebooted with the new flex cable I noticed how my phone stopped shining into my face at full brightness - if your brightness sensor gets stuck reporting the same (low) value this means your flex cable is on its way out!)
earpiece speaker
status led
touchscreen
screen (non-alignment with edge of screen, visual artefacts)
screen (fade to black/power interrupt)

I'll for sure keep that in mind. Mine is still going strong for the time being, but it's good to know some warning signs if I need to replace parts or if it's time to get a new phone

Replacement parts all the way, the repair was 15$ and it feels as good as new! Well, it could do with a new battery but that's just another 5..
Just realised that the proximity sensor should actually be added to the very top of the list - just noticed that faint red light when taking a phone call, don't remember seeing that in almost a year :]

That's not a bad cost at all. I know I'm going to have to replace my keyboard in probably 2 months or so (maybe sooner) because some buttons are starting to not work. Other than that fact my phone is currently still going strong for being going on a 3 and a half year old phone

Black Screen, phone still works?

Hello XDA members, this time I'm writing to all of you to tell you something that happened to my Optimus G E987 from Claro Argentina, also, to ask you something related to the topic.
I bought this phone about 4-5 months ago, and I have taken really good care of it, without using any film protection or case, it was working perfect and with not a single scratch on it, not even a little hit.
But then, some days ago, I decided to "protect it" a little bit, so I got one of this:
htt-p://i[dot]imgur[dot]com/YtgK1aS[dot]jpg
htt-p://i[dot]imgur.com/la1kI5e[dot]jpg
(Sorry, I'm new to this forum so it won't let me post links)
I used it like.. dunno, 3-4 days. One night, my phone was on 53% battery, to lazy to charge it so I just let it like that. Next day I gave it some use, so it dropped to 33% of battery life, I had to go work so I turned it off. When I finished, I tried to turn it on again, but nothing happened, tried more times and nothing, then I noticed I liiiitle light in the screen, the phone was turned on, but with REALLY low visibility, almost everything black but with a little of sight.
I though it was just a battery problem, so I charged it, but to my surprise, nothing happened, well something did happen, the little bit of sight that I had just went full black with no visibility. I noticed that the touch screen and buttons actually worked, I could "easily" navigate through the phone by just using it as normal, but without seeing (you can do this by just knowing your phone a bit).
And that's the story, basically, after using that case, the phone "casually" stopped working properly, all I got was a functionally phone with a black screen.
I managed to connect it to my pc through wifi and launched Android Screen Cast, to see what was happening on my phone. The glow was at 100% (I tried changing it) and everything seemed normal.
If you don't want to read, here is a TL;DR
>Bought Magnetic* Flip Stand Leather Wallet Case for Optimus G
>Some days after, phone screen stopped working (phone was still normally working, just with a full black screen)
About the Magnetic thing.. is there any possibility that this was the problem? the magnetic thing?
Btw, I sent the phone to tech service because it was still on warranty and they have me a new one, now I'm scared of putting it again in the leather case I bought, I don't want this to happen again.
Something to comment? hope you can give me some advice, thanks in advance!

Also having similar problems as you. Somehow, i am quite sure its the stock rom causing the problem.

Had the very same issue few weeks ago, had to send the phone back to LG ( who replaced the motherboard :/).
I was also on stock rom, had root and unlock bootloader (of course I clean all that **** before sending it back).
For my part, I was unable to go to recovery and download mode was quit impossible to access (may be my finger fault )
BUT! some time if I let the phone off for a moment or spam the power key, the backlight turn back on until I power down the phone, so it's could be a software issue ...
Anyway, an other info, when the backlight was off, if i tried to change backlight level i was getting a error message about overeating or something like that...

HTC 10 Half of Display Not Working After Screen Replacement

The battery on my HTC 10 was completely shot and needed to be replaced. I'm a careful person by nature and this being my first phone repair, I bought an extra screen just in case something happened getting it apart. Followed a guide by jerryrigeverything on how to take apart the phone, got the battery replaced, everything seemed to go smoothly. When I went to test the display before screwing everything together, the new screen I installed lit up, but the right half of the display only showed as a repeating segment from the middle of the screen. Thinking the connector was loose, I disconnected and reconnected the display and made sure everything was tight: same problem. I reinstalled the original display, which I made sure had worked after cutting through the adhesive before I disconnected it, and now the old display is also showing the same issue.
The touch screen on the broken side of the display still works, I'm able to type PIN numbers and whatnot even though I can't see them properly. Only thing I can think of is maybe the connection actually got some debris or something inside of it? I don't think I damaged anything, as I was super careful, but it was also my first time opening up a phone.
Sorry for the inefficiently worded post. Any help would be really appreciated.

Did you resolve this?
I have exactly the same issue you describe after my screen replacement (with two new screens) Believing the first was a dud.
I have done many screens/batteries on my m7, m8's previously never having a problem.
I'm currently back to running my M8 and miss my 10!
Anyone reading this and has any suggestions they are all welcome!!
Thank you in advance

Exactly the same issue this guy has
https://youtu.be/RpdCuMiTOn8
I'm now wondering if it is just bad aftermarket screens?
Has anyone else replaced their screen successfully, if so where did you get the screen?
Thanks Rory

I have been having the same problem. I just tested screen number 4 that has the same exact problem. Is there a specific brand that is known to test well?

I dropped my 10 in water at work...believe it was a salty water at that. It stopped working completely. I opened the phone to check the internal components for damage and I broke the LCD doing so. I replaced the battery and the screen at almost the same time. I think it may have been a week or two apart.
The battery is still working. The screen worked initially but the phone kept getting really hot and the heat kills the phone. I tried keeping it cool at all times which kept it operational. It hasn't been activated since I quickly replaced the phone with another of my lines upgrades. I went back to the phone to check it out and try using it as a replacement for my daughter but the screen no longer works.
The battery charges just fine...the led light indicates that well. I've tried reinstalling it several times with no success getting the screen working again. I tried the original screen to check and I could see light and it was responding but its not usable so I'm stuck with a phone that has a new non-working display. I think the brand was called DIYRepair or similar.
If anyone has encountered this and has advice...I'd be happy to try anything.
