Green trackball light won't turn off - Nexus One Q&A, Help & Troubleshooting

Hi, I recently was using my nexus one and the green trackball light just automatically turned on (solid color not flashing). I cannot get it to turn of no matter what I do. I have already tried wiping, reflashing, battery pull, and hard reset. The green light turns on immediately after powering on the device. Any help is much appreciated.

Very strange I've herd of a red light that wouldn't turn out it's sign of a hardware problem (water damage I think) but never a green one
What were you doing when it went on??

I have also heard of this problem (or at least I vaguely remember something like this). On the one I remember, it turns out that some piece got bent and came into contact with something from the trackball. It required taking the phone apart to remedy it.

I had a similar thing a few times: After confirming green notification light (by GoSMS), it has been glowing further at very low brightness. It only went off when disabling TB Notification in setup menu.

Last night the green light started flickering while charging, but this morning it was solid green again... it really is annoying and is a battery drain.

I am going to assume you have cm7 or cm something. If you go into the trackball notification menu when you can choose color and what not, select the application in where you picked green. Then hit "flash test" and hit "ok" when the light is off.
It got stuck for me too and this is how I fixed it.

Paintball, did you fix this? Mine also displays green 24x7 and causes serious battery drain. My daughter drooled quite a bit on the dock charging connectors, so I suspect something is shorted, but it's also been dropped (same person responsible for the drooling), so something could be bent as well. FWIW, I have no trackball alerts set.

Stuck in the green as well...
I have the exact same problem! In this case my girlfriend drowned the phone with lemon gatorade on her beach purse our last vacation a week ago, so I believe that's the problem: something is wrong inside the N1. I'm going to a phone repair shop see what can be done.

Cause of RLoD?

I've noticed a lot of people have issues with their Tilt randomly dying and not turning on again, but having a red LED, hence Red LED of Death (RLoD). I'm in Canada and got an unlocked AT&T Tilt, so no warranty for me... wonder what the cause of RLoD is so I can try to avoid it
I don't think anyone has narrowed it down to any certain factor that causes it. I could be wrong, I have been before.
Power circuit
Red light is related to the power circuit. If there is any fault in the power circuit it shows red light. It might be the battery or the contacts or the charging circuit!
This is just my guessing because I did a search when I got the RLoD and from the various comment I could guess that its the power failure for whatever reason!
PS: I got my phone recovered from RLoD using the so called CPR method (search the forum to find what it means if you dont know already)
PS: There is no particular reason to get RLoD. It happens randomly. I babied my tilt but still got it so its not particularly depended on usage!

WTF: LED light constantly on/won't turn off

My camera led light just started acting funny an hour ago. It turned on and it si now impossible to turn the damn thing off. It still stays on when the phone is turned off. I've tried removing the battery and then put it back again. As soon as the battery is in, the light turns on again. I've tried a soft reset and ultimately a hard reset. Light remains on.
Don't want to have to go to Sony for this because I bought the phone off the bay a month ago and therefore don't have a receipt so it won't fall under warranty. Anyone have any ideas? What a pisser.
hi,same here
I think its a hardware issue where the cables have been short and are giving direct connection. I dont know if this will work but try to tap the phone a little hard on your palm. If its just a loose contact it might get sorted. This is a very crude way.
You guys want help or just venting air?
Great story.... so ?!
If you guys want venting off air, that was it! If you are looking for help however, then KINDLY state some info, like:
what the frak is the phone model, firmware, recently flashed, if so to what. Branded or unbranded, built date, etc.!
After that, perhaps a few answers can be expected
MichaeltheImage: I doubt that in this case this had anything to do with software because of the fact that it remained on after a boot or when the phone is off.
Moleculez: Yesterday it ended up fading by itself after 2 or 3 hours. This morning it started again as I removed the battery. Tapped the led side of the phone on my palm a few times; and it worked. Thanks.
"Anything mechanical, give it a good bash."
Incase someone is still looking for a way to fix this problem:
I managed to pry the plastic covering off of the camera lense/ LED with a needle.
All it took was a slight nudge on the LED cluster to reposition it. It was situated slightly off to one side, causing the short circuit which lead to the LED being constantly lit.
Problem is, in my initial frustration I poked the LED and broke it which, as a result of the short, meant that although the LED was no longer lit it still drew power from the battery.
The only way I know that the later fix worked was by using a power consumption monitoring tool to verify that the LED (and the short circuit) was no longer drawing power.
Awesome.

[Q] Notification LED stuck on green??

Hi,
I have noticed a few threads about the trackball light being stuck but couldn't see one about the notification light. It comes on green from the moment the power button is pushed and stays like that whether booting normally or in recovery. I have tried a full wipe and reflash but nothing seems to work. Just noticed it yesterday, the phone did get a bit wet in the rain and so this could very well be a hardware problem. Any suggestions on things tp try? The phone is not wet now and wasn't severly rained on but have noticed the battery moisture detector change colour. I have tried a different battery with no luck of sorting the stuck green light.
Hope someone can offer a solution!
Thanks
Anyone anything?
I am also suffering from the same issue.
did anyone get this fixed?
already ordered a phone dismantliing kit from dealextreme... will try to peek inside and see if I can get it solved fro within..
I'm having the same issue.
It did stop for a couple of weeks after (I think) I was button mashing on a dead battery. The problem returned however.

If the moisture indicator changed colors, it got VERY wet from the rain. It's a pain in the rear to make these change colors without direct contact to moisture. Something you can try tho, and this will take a couple days...
If the phone is COMPLETELY dry, proceed... Otherwise, put the phone inside a bowl of rice for 2 days...Make sure to remove the battery, sim, memory card, and have the screen slider open during this process. If you can get a hold of silica, this works better.
**Put the phone in blue light mode. (Hold trackball down and power on.) Leave the phone like this for a few hours... Once this is done, DO NOT reboot the phone. Pull the battery. Reinsert the battery and boot into recovery. The light should now be off.
This tricks the phone into thinking it's at the factory, being repaired... Nothing actually happens, because you don't have a Diagnostic SD card.. This worked for me. May be a fluke, but still worth a shot.

Brighter notification LED ?

Hi, I think that the notification LEd of our HTC One is really poor. It really small and also not very bright, so it's very hard to see if you are not in a dark place.
But I noticed that when the battery is empty, or nearly empty, and you plug in the charger with the phone turned off, the LED is much brighter than usual.
So I wonder if it would be possible to make a hack for increase its brightness for every notification.
Thanks!

+1 here. No solution yet...
My led died last December. I don't miss it. But I was on the search for a brighter light too. I know that there are some hacks but I don't know exactly where and what.

Are you sure it's not just covered with dust or something? Try cleaning out with a toothbrush, some people "recovered" its led and loudness after cleaning

Yeah I'm pretty sure. I cleaned it very often it's dead and I don't care anymore. It's not worse to me.
Okay, I fixed my LED brightness.
It really was very very dim in phone's standby regime. Entering the bootloader or and other on/off procedure was setting orange led ON FIRE! That means there is a lot of power getting lost somewhere. In the /system/sys/class/leds/amber and /system/sys/class/leds/green there is a file named "pwm_coefficient" that determines LED's strength. I was unable to edit it on my (stock 5.0.1) kernel, but somebody may be able to do that, and alter the default value of "5" to something like "255" which I believe is maximum.
Anyhow, as a last resort (being so frustrated not being able to see my notifications on time) I decided to physically clean the LED's hole. I used an extra spiked toothpick (just give it a nice touch with a sharp knife, to make it super pointy and thin) and stuck it inside, rotating vigorously. It turns out that was it, it's as bright as new.
Still I wonder why dirty LED was shining brighter prior to boot?

Green light when connected to computer

So, one year ago, my C6602 felt on the water, for my bad, some of the waterproof doors were open. At first, it didnt damaged it at all, so i managed to turn it off, and wait cause we have a person who fix eletronic things. But, i was stupid. Even knowing that this would damage the phone, i did turned it on again...at first it were ok. One hour later, touch stoped working, couldnt turn the alarm clock off...then the screen goes off as well. Well, i did take it to stores who are specialized in cellphones and all of them told my cell was dead. Today, i decided to open it to see what the **** was happening, it turns out that i couldnt figure nothing out by myself, buttt i put the charger and got a red light. I though, its dead already, nothing bad will happen heeh. I let it for 4hrs~ charging, pressed the on buttom, but nothing happened, oh, at first, when i charged it a little, when i press the on/off buttom it would gave me 3 red notifications blinking, but that time it didnt. Instead, it went to green, and i could manage to access the cellphone on the computer (internal memory), all my files were there. Also, when chargin, it first showed me a red light, followed by a yellow/blank light, and, therefore, a green.
There is any chances that the cellphone isn't dead? Its this sorta of protection of your data what happened? Or the screen is really broken (and, by changing it, it'll be back to normal)? Thanks.
It seems that phone is turning on, but displays nothing. It may be display fault, but may be display related pcb malfunction also.
