speaker and headset problem please help me

i own a tmobile dash and just recently i began to experience this weird issue.
every time i turn on my phone and i make or receive a call the phone automatically goes to speaker phone and their is no way of getting rid of it. even thought it says that the speakerphone is off. also when i play any source of music, whether its a video, ringtone, or even music it always plays in a very high pitch and their is no way of stopping.

Yikes! That does not sound good!

can anybody help me please?
this really sucks

for me, the first step would be to reflash the ROM (or hard reset), and if that doesnt work, talk to the provider about a replacement phone.

i did that already.
neither worked.
does anyone know how to fix this?

I suggest first Hard Reset the phone (two softkeys and power on and then press send). If problem persist, then try to reflash with a new firmware (you can find one here). If still not work, then it must be a hardware problem, I recommend you send it to T-mobile for a replacement (you have to put it back to original firmware). Good Luck

Help! My Artermis keeps hanging

Hi all
My t-mobile MDA III has developed a problem in the last 2 weeks in that it keeps locking up. When you look at the phone its looks fine, the green light is flashing away but when you try and switch it on, nothing happens and I have to do reset before it comes back.
I've tried changing the rom, I was using Black & Blue v5 for a few months and it was fine but that hasn't helped.
One thing I have noticed is regardless of which ROM I use, when the phone starts up it always says "Black & Blue v5"
A hard reset hasn't helped either
Any ideas?

Similar problems in here, without the "Black and Blue V5" situation.
I've allready exchange the battery, but with no success...

I've given up to be honest, I was on a call the other day and it switched itself off! I'm back using my old Nokia :-(
I'm due an upgrade with T-mobile but they can't make up their minds about when they are going to release the Diamond2, I guess I just have to wait.

Hi,
I'm dealing with this bug since the beginning..how often does it happen to you?Does it happen with a clean ROM,what apps do you install? In my case it's not so frequent but very annoying because,as you said, from outside the device looks like perfectly working (green light blinking)..but you can't even receive a call! As a result you have a nice brick in your pocket or desk without knowing it. Anyway I still think this could be a sofware problem...I have apparently the same bug when i do a full backup with Spb Backup:when finished and restarts automatically after 15 sec it goes into this "black screen" deeeep sleeep. Eveything goes ok if I manually choose to restart my device.My ROM is equipped with S2U2 running just after you switch on the screen,maybe it could crash the whole phone occasionally, cannot prove it...going to disable it and see. These are only impressions (and no solutions) but I can say that this problem occurs to me more frequently when i play hard with my Artemis (I mean flashes..install-uninstall things..). When the pocketpc is in normal use i must admit it's quite stable. All this to tell that hopefully the device is not broken...I got one motherboard already replaced and I can tell you that the symptomes where different (fading screen...watch out folks).
Ah,by the way: That "Black&Blue v.5" screen you have is the splashscreen from an old rom you flashed that hasn't been replaced by anything because maybe new roms you put afterwards didn't include any..You can take a look here to change your splash screen:http://forum.xda-developers.com/showthread.php?t=317726

I'm afraid this is a hardware failure, unfortunately I don't have the repair papers with me at the moment (i'm abroad).Try to take a look in internet,I'll do the same and tell you if I find something,keep tracking this thread! Ciao
Edit: there is a Customer Care Area at htc.com where you can write an email or call them. Here's a list of phone numbers from all over Europe: http://www.htc.com/it/CA_Hotline.aspx found with Google.
Edit again:If you consider to replace it yourself,you should take a look in eBay..it may be cheaper.

Will do that.
Tried other options, but ebay is suspicious..you can find something cheap..but what if it is the same like mine??
btw..today I got reply from O2 uk...warranty is expired for 1 month!!!!

My Evo stopped Vibrating!!

Ok my Evo stopped vibrating at all on everything. Even when I first boot it, the vibrate doesn't work.
I dont have the insurance, but can I still go to like a Sprint Repair Center and swap it or can they fix it?
Or do I have to send it to HTC?

First determine if it is hardware or software. What happens when you hold down the volume down button... Do you ever feel it vibrate then?

Nope its defiantly hardware

Seems like that would be a manufacturing defect covered under warranty.

Download an app called sound manager. After it's installed hit menu and vibrate settings and make sure they're turned on. (just to make sure, it doesnt hurt) Good luck.

Try dildroid.

lol tried all those trust me im not a noob i would know if its software def hardware HTC said it would take 2 weeks wtf!!

I had the same problem with my evo....it stopped vibrating at all and i actually found out it was a result of dropping the phone. i have to be extra carefull now with mine because if it falls it will stop vibrating again and i will be forced to drop it again purposely untill it vibrates again...lol

give it a good shake, mines done that once before and that was all it needed to start working again
edit: just noticed this thread is three months old...

Hey xHausx
xHausx... thanks!!! it worked like a charm, vibration is now working again on my 2 months old EVO.
Thanks again!

Having the same issue here. Could someone link me to the RUU that would correct this?
Original post:
Hi All,
I've recently realized that none of my notifications will cause my EVO to vibrate.
I rooted my phone using unrevoked about 4 months ago, and up until about a month ago everything was working fine, when the vibration notifications suddenly stopped.
I have tried checking all settings (which are set correctly), downloading the Sound Manager application, and most recently (today), flashing to the Fresh 4.1 ROM, all to no avail.
I have also attempted (unsuccessfully) flashing back to the original EVO ROM (3.2 i think), after setting S-chip back to "On", but was receiving an error message stating that the main version I was trying to flash is older than the current one.
Attempts to revert back to factory defaults also did not correct this problem.
I have been searching different sites for about 3 days now hoping to find some information on how to correct this or perhaps someone who has has a similair issue.
Any assistance would be appreciated.
Thanks in advance.

[Q] AuraxTSense_8.3 bricked after one week?!??

Hi all, the very best noob is posting here
I was enjoying the last AuraxTSense rom (AuraxTSense_8.3_Official_OTA_2.2_FRF91_A2SD +...) installed on 29/01. The display is SLCD. The mobile is branded, so I created-and-used a gold card. Everything was perfect until this morning when I noticed that the display was black and there was no way to come up with an image, or text ... (it's almost black, actually I can see that lights just barely).
Since the installation of the rom was successful, I do not think that the phone is bricked, but It's a supposition. Or not?
As described on forums, I've installed the rom RUU_Bravo_Froyo_HTC_WWE_2.09.405.8_Radio_32.43.00.32U_5.09.00.20_release_140022_signed to try to recover the mobile: I can hear the sound, the cell vibrates, ... but no more as in the beginning.
Any ideas?
Thank you!

would you mind giving some additional info like does the LED turn on, if plugged in to a charger? Does it turn on, if plugged into a computer?
Can you boot into fastboot(vol down + power)?
Did you do anything special before this happened?
How did you flash the ruu(from zip file or via computer)? Did any errors occour?
Also why would you try to flash a ruu, when you had no idea what was wrong or what you were doing? You might just have ruined it more. There is no way to know, but as it was able to run the ruu, apparently nothing was wrong.

Thank you for the reply.

The mobile charges with charger, and USB cable attached on the PC: while charging, the LED is orange.
When off, I can power it up using the power button: the mobile vibrates and after ~25 seconds I can hear the start sound. After ~10 seconds the home+menu+back+src button lights go on for some seconds.
The display, since the start-up vibration, becames barely lighted. While the mobile is powered on, if not used, after some time the display becomes dark and I can resume its lighting pressing the power button.
While the mobile is on, if I plug the USB cable in the PC a new drive appears; it's an empty (0 bytes size) drive - I have no SD in.
Can you boot into fastboot(vol down + power)?

I cannot say this because I cannot see anything, but when I boot with (vol down + power) the mobile does not vibrate.
BTW I can boot with (power+back), as I have used the RUU executable to flash and it worked.

Just followed the instructions seen on another blog/forum.
I can say that the behaviour of the mobile after the RUU update is the same of before.
Thank you.

to me that sounds like a hardware (backlight) fault...
But how could you flash the wwe-Ruu? Your handset was branded, wasnt it? Did you use the goldcard to flash the ruu? Remember to flash the original (=branded) ruu before you send it in for repair (if you do so)

RUU_Bravo_Froyo_HTC_WWE_2.09.405.8_Radio_32.43.00.32U_5.09.00.20_release_140022_signed
hmm isnt that for amoled phones.
try http://forum.xda-developers.com/showthread.php?t=869048
and if that isnt working flash rom that came with it and send it to repair.

Yes, I flashed using the goldcard; it was working very well!
The last app I installed was juice defender, the full version, updated two days ago from the market.
I'm trying with the link proposed by madman_cro, it's now in download.
Thank you.

2 things... would it not have been better to post in the AuraxTsense page lol? I've used 8.3 since release and its near perfect, sounds like a hardware error.... screen maybe gone? There was a spate of HTC screen problems
Sent from my HTC Desire using XDA App

I have had this happen twice on Auraxtsense. Both times removing the battery for 30 secs and then replacing and rebooting solved the issue. It eventually came back to life.
In your case it could be a hardware failure ......

Im trying to flash the rom proposed by madman_cro, but today is a bad day: update fails with ERROR 170
Yes AuraxTsense is a great rom, with no doubt! I'm not considering the rom as the origin of the problem, but it would be nice to discover what's wrong in my mobile
In the case it's an hardware problem, I've asked HTC for assitance...
(PS: I have had no way to post in the AuraxTsense page as this is my first post)

oh one more thing(nearly forgoten) try to read this tread and see if it helps

As you say yourself this sounds like a hw error, and such it has nothing to do with auraxtsense, so why the hell should he post it in there.
But it does indeed sound like a hw error. So you will probably have to ask htc, if the prober ruu doesn't solve it. Also slcd brick only happens after flashing a wrong rom/bootloader, so it should not possibly appear out of nowhere.

Why the hell would he do that? Because at that stage a hardware fault was suggested but not confirmed ... so why the hell not?
If it was a problem with the rom like he thought it could be, that would of been a good starting point!

I had the same thing happen with a Blackstone (Touch HD)
Don't know if this is any help, but I had exactly the same thing happen with my old Touch HD. There was a util I found that allowed me to view the phone screen and drive it via my pc through the USB port. This helped in making sure that the only issue was a lack of display, and flashing and returning to stock before sending off for repair. Not too sure if there's something similar for the Desire.
The problem was initially diagnosed as a loose connection within the phone, and the repair center fixed it and sent it back to me. A couple of weeks later exactly the same thing happened. After replacing the mainboard on the second repair visit it was all fixed and worked well (until I fed it too much voltage from a charger, but that's another story). I'd suggest that claiming this experience as your own and requesting a mainboard replacement up front may be the best way to avoid too many service visits.
You'll know that they have replaced the mainboard as they'll issue you with a new IMEI.

selling it on ebay
Thank you all! My experience with support services in Italy and the fact that the phone has been rooted/flashed, have persuaded me to put it on ebay, as is. I still haven't found the solution, so I don't know if it's an hardware problem or something else. In the doubt, I'm selling it as not working.
Hope I will come back with a new desire...
Thanks to all the forum for contents and kindness

Is it not under warranty??? Its still covered if the changes you made didn't cause the issue ( I think lol)
Sent from my HTC Desire using XDA App

Although most people have said this is a hardware error (I'm inclined to think the same) have you actually tried to hard reset the phone just incase a setting is messed up somewhere and is actually displaying at 0% backlight. Very likely it won't work but is at least worth a shot before you get rid of it on Ebay

trying again
Hi warlordxxx, having the possibility to use another phone (do you remember the 7650? ) I removed the desire from ebay and I'm now trying to best discover what's happened, as I think it's not an hardward problem too.
I'm following the directions posted on the androidiani.it forum: maybe my problem it's just a video driver problem. I will let you know the result of the operations.
Have a nice week.

HTC One X Screen won't turn on, touchscreen still work???

I have been using the HOX for over 2 months now but this morning my phone display suddenly doesn't turn on even the backlight key still on and touchscreen still work ( when I sweep my finger up the unlock sound still play, and I can even adjust the volume of the phone, etc... ) I have no ideas if this is a software or hardware problem and how to solve it, I'm still on Stock Rom, Stock Kernel,... Please help me

try to reboot pressing power button for 10 seconds, if it'll not work, it can be hardware problem, as i understood you haven't unlocked it, so you can send it to htc and they will repair it, or if you can, you can change it by yourself,

have you tried starting in bootloader and factory resetting?

So the screen works in bootloader?

Same Problem
Hey, ive been using my international HTC One X for about two months too now and there have been no problems. ever since the update to 4.0.3 ive been facing exactly the same problem. The screen does not turn on a lot of the time but the touch is active. Have you found any solution to it?
It would be great if you could help me out.

I have the same problem now. Using it completely stock, the screen doesn't turn on. Well.... Except for the times I visit the Vodafone shop to get it fixed....
Their first reaction was a defect in the screen, so they ordered a new one. I brought it yesterday again and it is now in for repair.
I don't know if this will solve the problem. How did they fix yours?

hey guys
I had this problem a month ago, i know its frustrating.
anyway the only solution is factory rest from boot loader and flash RUU (worked for me)
the first time i had it, i did a factory reset, all my pics music were gone, phone went back to normal( stock, locked)
after a day the problem appeared again, second rest.
flashed RUU and the problem is gone. thanks god i have been using my HOX about a month science that problem and every thing is working great.
im sure its a software issue and I recommend every one to back up their files(pics,music)
just flash RUU and good luck

Lol, exactly the issue I had recently had with mine. Sent it backto htc, let's see what they would do about it.

My colleque has the same issue with his One X.
It started with suddenly everything on his screen looking "zoomed in", so everything double size, looking ugly as a mofo, and not usable. After locking the sceen and unlocking again, it was fine.
Monday suddenly also screen didn't want to turn on anymore. Did the hard reboot for him, and it worked again... Untill he locked his screen and wanted to unlock, same issue.
Also, that time when doing the hard reboot, screen didn't turn on at all. Did another one, and worked again.
He's now sent it in for repair, this definately sounds like ahrdware issue, even full reset through bootloader didn't help.

Yup, exactly the same problem I'm having, I sent it to HTC, they said they fixed it by replacing the motherboard, but now it is happening again, I will have to send to HTC again.

This just happened to my phone... Has anyone else solved it? Is reset and flashing RUU the solution?

I have the same problem right now.
It started last week when I was using Flipboard and suddenly everything started zooming in and stuff (same as mhulsegge above). It was resolved by locking my screen and unlocking it.
Last night, i've been getting the black screen when I try to unlock my phone. The touchscreen still works but the screen is just blank. It turns on if I keep locking and unlocking, but it's getting annoying.
My phone is an international One X (duh) bought in Hong Kong and I'm currently living in Canada so it would not be possible to send it back for repairs. Plus my phone is rooted and I am currently using the latest MIUI ROM (2.9.21). I have been using an app called "Sleep" which tracks your sleeping patterns. It requires you to place your screen face down on your bed when you sleep and the accelerometer will track your sleeping patterns and wake you up at the most optimal time. I assume that for the accelerometer to work the screen has to be on, so I am wondering if this can be a screen malfunction (overheat or overuse) problem since the screen has been on for so long (every night when i sleep for around a month).
Since sending it back is out of the question for me because of where I am living right now and I have voided my warranty, I am downloading other ROMs as we speak and seeing if it is a problem with my ROM. I will keep you guys posted.
-edit- I have tried factory reset and reinstalling my ROM (with a full wipe). Still doesn't work.

It´s probably not your rom since I use CM10 hand have the same problem and others have even been running stock and had this problem. The only one who seems to have solved this (at least in this thread) flashed RUU, so guess I´ll go try that now...
Would be great to hear if anyone else has solved it, and how!
edit: This has to be a hardware problem, if I push on the screen it starts working! Its like something is loose, and when i press on the screen it gets connected again.

Good tip, but I tried a gentle two-fingered push (zoom pinch) and the backlight turned itself on with very little pressure, certainly not enough to flex the screen. I believe that it is a state issue related to zoom, but will try again and report if the issue returns.

Screen black after replacement lcd display unit
Hi,
My HOX touchscreen was broken, the touch and everything was still working. I ordered a replacement lcd display Unit and replaced the complete display and touch. After replacement the screen is completely black but the phone still works. The touch buttons on the bottom still work and i can use the volume buttons. I replaced the lcd display unit very carefully and i am sure nothing is broken etc. So the touch is working but the screen is black. I tried 2 display units and both show me a black screen.
Does anyone know how to solve this problem? Did i forget to do something during the replacement?
Please, i need some help with this issue.

OneX has too much issue with Screen . WTF with HTC?
