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.

[Q] Phone only boots into safe mode because volume rocker broken

Help guys, my phone went swimming in the sea. I turned it off immediately and let it dry off, but the volume rocker doesn't seem to be working anymore. It does not react to my touches, but is constantly pressing VolUp or VolDown (I can't tell which one).
When I first started it, I got a bootloop, so I went into recovery and reflashed my ROM. It is booting now, but only in safe mode (since the volume rocker is constantly pressing). Is there any way to disable safe mode, maybe via adb or something? Or to disable the volume keys software-side?
The OS is Jelly Bean by the way (not that it matters). Everything else is working perfectly fine.

Probably, you'll need to pull the phone apart, and either clean, or replace the small volume rocker board. You can find them on eBay for pretty cheap. It's usually only a last resort to look for software fixes for hardware issues. The Nexus 4 is relatively easy to disassemble and replace parts, since everything is modular. I don't know if you have Radio Shack or an equivalent in Germany, but there's a duo of products called DeOxit and ProGold. DeOxit cleans contacts (silver, copper) from oxidation, and ProGold increases conductivity. This might be enough to clean your volume board contacts enough to work without replacing it. Of course, it is possible that the logic board is damaged, in which case you might be screwed. Replacement motherboards cost as much as a used phone does.

To be honest with you falling in the sea usually means a dead phone, saltwater is highly corrosive.

Thanks, I'll try that. Can you tell me how the screw type of the Nexus 4 is called? So I know what screwdriver to buy.

torx 5 on the bottom, you need a small phillips for the inside screws.

[Q] Help! My volume buttons won't work think I broke ribbon cable

Long story short my S5 got wet and I took it apart, but when I put it back together the volume keys aren't working. I'm not sure If I need to buy the midsection of this phone that houses the volume and power buttons or if I need to buy a new LCD glass. I think I may have cut the ribbon cable on the left side of the LCD screen. See the below image of how the two cables look like they should be connected but are disconnected. Every tear down and pics of this phone show these two cables being connected. Can someone please confirm if I did indeed cut this cable and if it does control the volume up and down buttons? I want to exhaust all my options before I break down and buy the midsection. If I did infact cut the cable then it will be a costly mistake. Any help would be appreciated, thanks

Im not sure if you did but for now you can download a volume widget till you can have it looked at
Sent from my SM-G900W8 using XDA Free mobile app

I wish it were that simple as I have another problem with my phone, but in order to fix that problem I need to fix the volume button problem. My phone is stuck in boot loop from getting wet. It's unrooted and I could access the screen to wipe data when the volume buttons worked, but even after trying to wipe data it would still stay in boot loop. Now, If I help the volume down, home, and power button I could access the Downloading screen. This screen will give me hope of reloading a new OS, but I can't get to this screen till I can figure out my volume button issue. I"m hoping some one can shed some light to my question above. Thanks

My S4-GT I9505 is stuck in Recovery mode

I have a Samsung S4-GT I9505 with a volume up damaged or stuck key , so it always boots into recovery since the volume up is stuck and in order to get it boot I have to keep pressing on the volume down while it is booting .
I took my phone to many repair shops and no one knew how to fix this issue , I know that while I'm in the rom I can install any audio widget to get the volume up but to me this is not a solution .
please , if any one knows Samsung GT-I9505 volume key ways or any clue on how to fix this issue , kindly I ask you to provide me with your experience .
thanks alot in advance

Take the phone apart so you can see the motherboard, then reassemble the phone. Sometimes the buttons on the case get out of whack and press against the volume control buttons on the motherboard, causing this issue. If that doesn't work, replacing the motherboard may be your only alternative, as the buttons on the board are not user replaceable.

thanks for the reply , but I did took apart the phone many times and no success .

Then it's most likely the button on the board that has gone bad. I am presuming you tested the button on the board while you had the back off?

Screen won't turn on, touch will works

Hello, recently I damaged the screen on my s8 where the screen wouldn't turn on and no input would work, so I figured it was the LCD and digitizer that needed replacing. I've replaced those parts, and the touch works now but the screen never turns on. I turn the phone on and see the blue notification light that turns on when the Samsung boot logo comes up, but can't see the boot logo itself. I can unlock the phone because I've memorized the pattern/placement and I can hear the volume change sounds when I adjust the volume.
I've tried cleaning the PCB contacts, holding the volume down + power button, holding volume up + power + bixby, and I've changed the battery and verified it works. Anybody know what could be the cause? Faulty screen? The company I bought it from is asking me to send it back to verify if the screen is faulty, by I'd rather not go through that trouble if the problem is with my motherboard or something. Although, because everything else works, it does lead me to believe the screen itself is bad?
