Trackball stuck - Nexus One General

Think my trackball is stuck, although moves freely and can press down OK.
Turning my phone takes me striaght to bootloader. Turning phone on holding power and volume down takes me to fastboot - normally trackball would have to be held down as well.
Volume up/down do not work in bootloader.
Advice ?

Your assessment sounds about right; I'd get in touch with HTC a.s.a.p.
Never heard of this before with any of the HTC trackballs.

This happened to me when I had my second G1.
Had to get a new so def look into a replacement.

Crazy volume problem

Basically, it is as if the top volume button is held down, and the volume is continuously going up on my HD, even when I try to turn it down, it shoots back up again, and is stuck on the volume screen. Sometimes, if I turn it down to silent, it will stay silent for a few seconds, then the volume goes up again and keeps going up.
Really annoying as it means the phone is basically unusable as I'm pretty much always trapped in the volume screen!
Any ideas?
I would suppose that a button is stuck!
Take of the back cover and take a good look at the buttons to see if anything could be wrong!

That's what I thought, but it looks fine to me
I had the same problem as you but I then realize that when I was putting down the volume while in a conversation was my face pressing the screen and increasing again the volume...could it be your same problem?

Nope, because it happens if I don't touch the phone and just leave it on the table
Have you tried a hard reset?
Do a backup first.
Turn off the phone. If you can't pull the battery out.
Hold the volume up + down at the same time then press the power on button for about 1 second. Let go of the power button while keeping the volume up and down still pressed down.
You should see a blue / green / red screen then just follow the instructions on screen.
If this doesn't solve your problem then most likely something is keeping your volume up button depressed internally. Take it back for repair...
The volume slider malfunctioning is a big one on HTC devices known issues. I've had the same problem with my elf....and I've seen plenty that do too. Your best bet would be to take it to an authorized service rep. Sucks I know
Try to remove the cover and use it... the pressing mechanism is on the cover...

Tried that, still the same problem.
I'm going to try a hard reset today, if I still get the problem, going to ask Orange to replace it. I wonder if they'll let me pick another phone, I'm getting a bit fed up with the HD!
I have the same problem, it occurs randomly and I discovered that if I quickly press the power button to stand by the phone and press it again to exit from stand by, the volume bug disappears and phone starts working well again. I thought it was a software bug but I still have it on 1.19. It rarely happens now on 1.13 was more frequent.

[Q] -sigh- g1 'rainbow screen' - EXPERIENCED USER(S) please.

i'm sure this has been done to death, but, through my searching, i haven't found an actual concrete solution.
i purchased a g1, knowing that it was stuck at the rainbow screen. i thought it'd be an easy fix, but, in my case, it seems not. i'm a uk user, so have flashed the rc7 update, and NOT the 29 one. yes, i pressed the camera button, and THEN the power button, whilst the g1 was turned off. once successfully flashed/completed, i press the 'action'/trackball key, take the battery out, and turn the phone on, only to see that the rainbow screen is STILL there.
what you might need to know:
DREA110 PVT 32B
HBOOT-0.95.0000
CPLD-4
RADIO-1.22.12.29
Sep 2 2008
Serial0
so, if anyone has a full-proof solution that will get my g1 working again, i'll be extremely grateful. if not, i'll put it on e-bay. is it possible that my g1 is permanently bricked?
How about NOT pressing the trackball?
However note that pressing the trackball during bootup SHOULD put the thing into BLUELIGHT mode (debug console).
Typically, if it turns on straight into the bootloader, it means that your CAMERA or BACK button is stuck. Try pressing each of those buttons a few times and then turning it on again. If not, you may need to disassemble.
but, i mean, once the phone says Update Complete
UPDATE SUCCESS,press action (trackball) key,that's when i press the trackball key, as it tells me to. the camera and back buttons certainly don't feel stuck, ...

I don't care what they feel like. One if them is stuck.

He is right, if it boots into bootloader (rainbow screen) that means your camera button is stuck, even if it doesn't feel like it.
i just took apart my htc dream... im experience a similar problem.... i measure the ohms on the switch for the camera button, open, it shows about half contiunity on my multimeter(analog), and when the button is pressed, it registers a full short, as it should, on both sides of the switch. I will try unsoldering the camera button at some point tomorrow, and will try to post my results.
does anyone know if those switches are meant to be completely open when not pressed??
EDIT: will be heading out to my job in the next hour to use the hot air station to remove the camera button, and clean up the contacts on the board... if this doesnt work, does anyone else have any other ideas??

ok, so i just unsoldered the camera button off the main board, and it still comes up to the bootloader.... what next?? ive flashed the dreaimg.nbh file, and wiped the phone. i can press the home and pwr button and get the recovery menu, but even there, flashing anything *.zip doesnt make a difference... ideas now??
EDIT:So i just got another g1 with a cracked screen... i switched out the mainboard. with a different mainboard that worked from a different phone, it still came up to the bootloader screen... i then switched the buttons, not the camera button, ironically, the other buttons.. i switched the whole front plate(send, home, back, end, menu buttons/trackball panel). now the original mainboard works fine... just no camera button cuz my hot air station at work killed the button. try that and let us know here. see if that works for you....
EDIT2: Heres a thread that i just opened with that last explaination, as well as a story to how my day preceded with this phone... http://forum.xda-developers.com/showthread.php?t=781143 enjoy!

[11 April][Q] Power Button Not Working

Power button does not respond at any point.
*EDIT:except after battery out for a long time, then power button WILL turn the phone on, but then continues to not function as per usual.
However, the phone automatically turns on as soon as the battery is placed in, so it's not dead at least.
Also can not get the phone to be recognised on either of two computers (one running Win 7 and the other Vista) always get "device has malfunctioned etc"
Have re-flashed a ROM from SD but same problem. If holding down the Vol Down on start up (putting the battery in) I can get to bootloader, hence the re-flash. But holding down both gets to the hard reset 'warning' screen, but it won't let me press Vol Up to actually do the hard reset.
All in all a frustrating problem which means I have to remove my battery to turn my phone off and have to use the option from Windows Menu to lock the device.
Any help with any of the problems is greatly appreciated.
Also Power Button mechanical function is still normal.
Many thanks.
Sounds like your end key has become faulty as well as your volume up button. Both of witch are common issues, especially the end button, but most peoples volume down button wears out first. This is do to the fact that the end/power key is in constant use from turning on and off the HD2 or from getting MAGLDR to pulled up a bootup for those running NAND Android. Also the volume keys take a lot of wear and tear from constant volume adjustment especially if you listen to alot of music on your HD2. Plus the volume ..down key takes extra wear and tear from being used to enter bootloader.
hello
hello vsem
Yes it does seem that way, however I have had teh battery out over night, when I put it back in this morning it DID NOT automatically initiate the boot sequence. But it did after I pressed the power button, so it must have read it to some extent?
Also when the phone is on I can change the volume up and down as per usual, its all a bit strange.
Any other way to initiate a hard reset other than that menu?
Thanks very much!
It seems you are having a hardware issue, try sending your device to the service centre.

[hack] broken power button "fix" - remap genius

UPDATE: This remapping allows the Genius button to "act" like the power on button while your phone is on. Having trouble getting it to actually turn the phone on. Any thoughts?
Dead or dying power button on you MT4G? Mine was dying suddenly and i didn't want the hassle and risk a warranty exchange and get a phone with a bad eMMC chip or screen. Also didn't want to pay $100 to get the power button replaced.
Using the guide found below, I just remapped my Genius/search button in hopes it will become a power button (UPDATE: as of right now, it can only act to shut off the screen and to power down the phone--powering on the phone via the remapped button doesn't work yet.)
http://forum.xda-developers.com/showthread.php?t=836702
The only difference: by key 183, replace FUNC_4 with POWER (all caps).
like when you press the genius button, it turns the actual phone on/off...or just the screen on/off? if it turns the phone itself on/off, thats pretty cool as my power button was getting a bit unresponsive also. you could also use the trackpad to wake up the device(not sure if all roms have this feature tho). but either way Ive never thought of this little mod, reps to you
I've tried remapping Genius and Camera (I know, potentially lose a factory reset option), NEITHER of these will act to power on the phone. They'll power it down and shut the screen off, but they won't wake up an off phone.
Could it be that the power button is the only button capable of turning the phone on (based on hardware wiring and $hit?).
I've tried swapping Genius and Home buttons...they work perfectly EXCEPT for as a way to power the phone on.
I've also read that you can power up the phone by plugging it in and holding down the home button. That doesn't seem to work for me.
There must be some other code that would make this work...
Thank you for this. With the TPU case holding the power button to power off the phone is a little strange. Cant tell if im pressing the button too hard or not. I do not want to press it harder than I need to cause I know how fragile they can be. Now I dont have to worry about it!
Getting a replacement
The remapping POWER is surely helpful to some...and prevents wear on the pitiful power button.
But with no clear, definitive way to turn my phone on, should the power button completely die (which seems like it will this weekend...it's worse each time), I'd be f*cked.
I did the web customer chat with T-Mobile to get a replacement. They offered me a Samsung Galaxy S. I declined that, saying I want a MT4G or better. They responded that the MT4G is out of stock and they don't know when, if ever, if will be available. This waste of time was about an hour.
So I CALLED customer service, explained the situation, the rep looked in their systems and talked with a manager and said they have *limited* stock of MT4G. My guess is that when something is *limited* they can't give it out as an exchange. Anyhow, this rep put in the order, making sure they had the MT4G in stock, and wondered why the web chat people said they were on back order. This CS experience took about 15 minutes.
Should have a replacement MT4G next week--hopefully good screen, good chip and good power button.
This is only my second exchange.
ANY changes to the power button behavior in the ROM are in effect only when the ROM is up and running.
You can't do ANYTHING to make the phone turn on using another button when it's off, without reworking the HW.

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.
