[Q] Question about buying a phone for parts - Galaxy S II Q&A, Help & Troubleshooting

I am sure this has been answer a million times, but I tried to search couldnt really find anything. I was jogging and my phone fell out of my pocket and I cracked my screen. Can I buy a phone with a bad esn and swap my motherboard over to the phone?
Also one more question, sometimes when using my phone the screen will go completely unresponsive and start randomly opening apps or calling people, I just uninstalled all of my apps to see if it does it again. I did read people had problems with this when it was plugged in, I have zero problems when charging it, it will randomly just start doing it, I do not have to restart the phone, just hit the power button to put into sleep mode then hit the power button again to wake it and it will start working fine. It does this when usings apps, such as games or youtube or really anything.
Looking forward to opinions,
Thanks everyone! :good:

Already did a factory reset, didnt fix the problem. Though I did read that heavy dust build up can cause your screen to do this. I took my phone apart and it was caked with dust/lint. I used qutips and alcohol to clean it out. So far so good! Also I wont be fixing the screen, I cant find a digitizer under $70, if I spend that much Ill just buy a used S3.
Ill report back in a week or so incase anyone has this problem this could be one of the things that fixes it.

touch screen stops responding after device wake up Help

hi guys,
i'm having this really wierd problem just started couple of hours ago, ok so the problem is that when i reboot my phone and get into windows mobile or android everything works perfectly however as soon as i power off and wake up the phone the touch screen stops responding completely and the only way i see is to hard reset the phone again and i have no idea whats causing it i changed roms , changed radio and yet i still have this problem so someone please help me out, i don't no if the touch screen is messed up or what
because the touch responds perfectly the way it should when i reset my phone but after i power off the screen and wake up to the lock screen i can't unlock the phone b/c it won't respond to my touch after that
so please help out guys
thanks
hm... try hard-reseting the phone. but back up your data first using some backup software like sprite backup
Tried that as well no luck any other suggestion guys

I had the exact same problem, and I had to hard reset everytime, but as soon as I would press the end key it would be unresponsive. What I learned is that right after you hard reset you should only try waking pressing other keys than the end key and let it go to sleep by itself. Also did you use any EVO android builds, or Android at all, not sure if it's relevant, but that's where it all went wrong for me with the EVO build. I do find it quite odd that quite a few people are experiencing the same thing with the touchscreen and it also seems that there really isn't a solution to this. I had to send it in for a repair, and it got fixed pretty quick. Perhaps this needs to be investigated more.
i have same problem with my htc hd2
it is so annoying. i will send to repair service too..
hey i have the same problem too ! did you installed the new c0okies home tab ? because i did and after that it start it messing up.. well i did a thread yesterday about this.. the only responses i got was to send it back to repair. I just did not turn off the screen for nothing today during the whole school day it almost finisihed the whole day, it last it me about 6 hours without turning off the screen, otherwise the touchscreen becomes unresponsive.
Temporary fix/test
I just fixed it temporarily, i fixed it by taking off the battery cover and pressing down on the htc logo (below lcd) and pressure on both the front and back of the phone where the htc logo is.
if you do this and it fixes it, you most likely have a dodgy lcd/digitiser flex ribbon cable.

[Q] Freezing HD2 after lock

I know there are hundreds of threads and articles posted about HD2s freezing with the lock screen but this issue seems different to me. My problem is that whenever I lock the phone the touch screen will freeze entirely. I thought a work around may be to install a different lock screen. After installing that I can get past the lock screen but the touch screen still is not responsive. I have no idea what to do. I already did a hard reset and it still does it. I would like to add that it is completely consistent. It happens every time without fail. In order to even use the phone I have to pull the battery and I get one use out of it before it locks and I have to pull the battery again. Does anyone have any suggestions? I would really appreciate it..
Update: I flashed the original ROM to my phone and the freezing problem still exists.. I have no idea what to do at this point.
Update 2: Narrowed down the problem to being the physical "power/end/lock" button. If I slightly press it but not fully it will go to the honeycomb style menu with all the apps. If I press it fully the screen will go out like normal but then if I restore it, the entire screen is locked up. Nothing will work after that until I pull the battery.
I've directly linked the issue with the power button. I dont know why all of a sudden the power button would have a different function. The work around I found is while the phone is locked and the screen is off I can press the green button to unlock the phone and the touch screen will then function. If I use the power button it will remain frozen. Any ideas what happened?
Hello,
I got some bad news for you, this issue is actually related to the digitizer (hardware) not software. What i would recommend is called HTC for a repair and send it in, it is covered by warranty, hopefully you have warranty.
A lot of people are having this issue, no-one yet has been able to pinpoint the cause, but here is the link a thread with similar problem:

Thanks for the reply. I do not think I have a warranty on this phone considering I bought it privately. Ill talk to Tmo and HTC and see what I can do. Just a theory, I may be wrong. But I live in PA and its been getting below 20 here lately. I noticed today that my work around didnt work when I was outside working on my car. Then I went inside and used a blow dryer to heat up the phone and it started working again. The end button didn't function properly but I could unlock the phone with the green send button. Perhaps the cold weather is shorting out people's digitizers? I don't really know how they work so that's why i said its only a theory. I bought this phone in the spring and didnt have an issue until now when it started getting really cold.

Help! Screen Wacked out!

Ok, so my girlfriend dropped her phone and cracked the screen, I ordered a new LCD/Digitizer assembly and everything seemed fine. She then realized that it had a dead line while playing Draw Something. I sent back and just received a new assembly and installed it. Ever since I installed it the screen will occasionally black out and lock up. It takes forever for screen to come back up and seems very random in how long. I try powering off and on to no avail. Once it does come back I get an error log in the notification pull down saying it just rebooted form an unexpected reboot error and I have sent this notification 3 or 4 times.
Things I have tried.
Taking apart and checking all connections as well as cleaning screen on inside and out where proximity sensor goes. I am seriously at a loss, it seems to work for a while on a fresh(actual battery pull) and work fine until it just freezes no button push except power button which shuts off screen and then never comes back except for the captivate buttons on the bottom. I have searched for answers but haven't found anyhing like before.
Thoughts?
Thanks,
Kevin
I know that feel bro.

I've actually had this exact same problem with my phone. I haven't replaced the screen but ever since the update my phone will do what hers does. It will freeze after a bit of use and I cannot do anything with it but do a simpull and then it will work again for a bit. I haven't been able to fix it. I have done factory resets, had the store reflash the software and yadda yadda yadda. I'm havinh my phone replaced now but it's frustrating not being able to figure out how to fix it when I feel like it should be fixable since it literally didn't even start until minutes after I installed the update.
It sucks.

Phone reboot before finishing flash and/or download

Hi,
My note has started to act weirdly not too long ago. i had a custom firmware installed on it and it was working fine. i decided to change the firmware to put it back on stock Rogers and again it worked fine. maybe 1 week or 2 after the phone started to go into boot loop, even keeping the display off and just vibrating. i've been able to get into the recovery and download mode. i tried several way to fix the boot loop but in vain. i left the phone on my desk for a couple of weeks since i didnt had much time to work on it. now i'm trying to start working on it but i ended up with more errors!
now:
- my phone does get in download mode but reboot by itself even before i have time to flash anything with odin.
- i've only been able to get in recovery mode once, tryied to wipe to factory, but then rebooted by itself again.
whatever i do now i can't stay in any modes more than 5 sec until the phone restarts by itself...
Any tips and trick to have my phone working again?
Thanks in advance!
It sounds like the infamous stuck power button has plagued your device.
Try flicking the back of your phone by the power button with your finger. That's been a common fix. Another one is flicking the power button itself. If those methods fail you can try taking it apart and cleaning it. It is a very small tiny microswitch. Spraying cleaners or anything from the outside won't work. It's not hard to take apart, but I hope flicking it helps.

Flick the back of your phone a few times.........I know " but I hear and feel it click", doesnt mean anything. Flick it
Some are not afraid and will open phone and clean contacts with alcohol and qtip. I am afraid though.
Flick it

I must type just a bit slower than you. beat me to it
Hey guys thanks for the quick answer. i really happy to know that it's a kind of common problem. the things is, could you explain me what you mean by flicking my phone? english is not my first language so i don't fully understand what i need to do :s like i should swiftly hit my finger with my phone by the power button to "unstuck" the button?
hummm don't mind that, i just took it appart, pretty easy job. so now, i spray contact cleaner on the switch itself?
Thanks

Again, thanks a lot!

[Q] HTC Droid DNA Stuck on Black Screen

Hey,
I'm new to these kinds of things like forums and stuff like that, so sorry if I'm not that clear with what I'm saying. If I could also get some criticism on the post itself and how I can improve, it'd be a great help!
I've had this phone since November of 2013 and this is my first time encountering this problem. After getting home from school, I took my phone out of my backpack and tried waking it(simply pressing the power button so I could see the lock screen), then I noticed nothing would happen. I tried again and again then noticed that the 3 "buttons" at the bottom of my phone were lighting up when I unlocked it, and disappear when locking it. Once I unlocked it, I was able to turn the volume higher and lower, listen to music(because I remember what the layout looks like before it had a black screen), and even (somewhat) use apps. Every time I hear my phone ring, it really makes me want to punch it, because I know that the phone itself is working, but just the screen won't turn on. Like even when I registered for xda-developers, my phone rang once I got the e-mail to verify my account.
I looked at a bunch of other threads before creating this one. Some said to hold down Power Button, Volume +, and Volume - for 30-60 seconds. I tried doing this multiple times, each time holding down the buttons a different amount of seconds, and nothing happened. I let the 3 icons at the bottom blink 15 times, wait a few seconds, let it vibrate, then let go. The longer I held the buttons, the more it would vibrate(about one vibrate for every 15 seconds). I hear the sound effects when turning it on and off("Droid" in the robot voice, then followed by some weird robot-sounding noises). Some people just said to let it charge, and I also tried that. Nothing happened, really, it just charged.
I've been thinking of letting the battery die out, but who wouldn't think of that? So I just ditched that idea. Tell me if I should try it, though, please.
My phone's pretty beat up, but nothing to the point where some parts of the screen would stop working, just two pretty big cracks on it. Sorry, I can't post pictures 'cause I'm new > <
If you guys could help me out with this, or just tell me if it doesn't work at all, it'd be a great help.
Thanks,
Joseph
Sounds like the LCD has been broken.

That sounds pretty simple. Would I need to replace it, get a new phone, or fix it myself at home?

I would replace the screen. Whether or not you want to do it yourself depends on your confidence, experience, and tools. If you've never torn a phone apart before, then you might want to find a friend who is handy or go to a shop because HTCs, in general, are not the easiest things to start with. And you'll definitely want to buy the already pre-assembled LCD+Digitizer combo as trying to separate the 2 would be more hassle than it is worth.
