Trouble Shooting my Nexus One Issue? - Nexus One General

I just picked up a Nexus One in Mint shape. Not a scratch on it anywhere def. has not been dropped in or exposed to water at all I know what to look for. It does respond but I get nothing but lights. Please have a look at my plug in results as listed and give me some input.
1. When I plugged it in last night I got a orange light in the earpiece screen.
2. Today when plugged into the wall or my computer I get a solid green light on the status led.
3. If I pull the battery and plug it in I get a quick orange followed by a quick green light.
The battery also does not get warm nor does it show signs of swelling. I'm trying to narrow it down to a bad logic board or Amoled/super lcd? Normally with a bad lcd in other phones you'll get a back light of sorts where in bright light you can still see the images. Possibly this isn't a characteristic of these. Also if I plug in this device or hold down the power button would it not automatically turn on. If so wouldn't I hear the boot screen or process and wouldn't it vibrate? I've never owned one so I'm not sure.

Nevermind I was told on Nexus forum to go with the old batt pull and it booted. Now onto the research for the cure.

That is the charging light. Green is full , the other color is for charging.

universal dead?? HELP red light!!!!

Hello, earlier today i felt the device was very warm, i tried to switch it on but it dint respond, even to a reset. when i plugged it into the wall charger all i get is the right hand LED glowing red.
HELP!!!!!!!!!!! how do i hard reset it or get it to work again!!!!!!
i would call in orange care, but im out of the country and i really need the pda functionality!!!!
Unlucky. The 'red' light on most HTC devices indicates a serious power problem, usually it means that the battery is dead (as opposed to simply having run out of charge) or very close to death. You can probably get it working again with a new battery, if the incident hasn't damaged any other components.
i had this with my JJ after I accidently let the battery run down, I plugged it in and led went red and unit would not power on, left it plugged in started scanning the manual and web about a red led, 30 mins later, JJ just switched on and all fine.
It's worth a go and ive not had problem since
i dont think that was the case...
i have a feeling it might have been a short or something, because the unit was SERIOUSLY hot.....
nothing i did worked....until............
final time before giving up, the light was still red etc.
i figured what the heck, either way its dead and im going to get a replacement.
i then gave it fairly hard thump
the red light disappeared. i thought to myself, oh crap, i've really killed it.
then i reset it............. IT BOOTED UP!!!!!!!!!!!!!!!
and all my info still intact......brilliant.....im still going to try and get a replacement when i get back, but thank goodness.
and here i was thinking the last computer to respond to physical violence was the old 486'es hehehehehe

Actually, it's called percussive maintenance, "the fine art of whacking a machine till it works"
hehe, i'm an IT technician and it's the first thing i try, especially with Printers.....
They don't teach you that on MSCA courses.....
I would recommend not using the machine too much until you can get a replacement battery if I were you. Lithium batteries will get very very hot (in some cases expand and ignite) if they are dis-charged too far. Most equipment which uses lithium technologies will have a voltage cut-off on the power input. As each cell is a nominal 3.3V-3.6V, this is often at around 3V in order to not discharge the battery too far. I would have hoped that this was a HARDWARE function rather than software. However with what you have described, if the voltage cutout was somehow disabled, then this could explain the problems.
Of the units that I have seen in the past like this, the red LED would describe the battery voltage being too low to safely power the unit (i.e. battery be dead). Generally a couple of minutes charge will bring it up to a safe working value. However, after 30 minutes this certainly should have been enough. On one of my motorola units, the battery has expanded a couple of millimeters as it starts to dissociate. It may be worth you checking to see whether the battery in your universal has distorted in any way.
Hmm the red light comes on mine all the time.
It just means the battery is low and the unit is charging. .
It should turn green when the battery is at or near optimum charge.
no....thats not the red, charging is orangy when i say red i mean PROPER red. battery is not distorted, and to the best of my knowledge the unit had a good charge, im pretty sure it must have been some kind of hardware short, and am going to call orange as soon as im back in the country.
dosent explain though why when i whacked it it started working again. the whack instantly made the light go out :wink:
i did a battery rundown test as soon as i got the unit, and posted the results on the forum, if the cut off was not working, i would have ended up with a red light then.
i dont have the manual with me now, but is there any documentation on the red light?
Found this site which had an online manual:
http://www.rich-michael.com/pdf/User Manuals/050802_Universal_Generic_Manual_English_CDL.pdf
What does the phone say in the Power Tab?
A really useful extract:
13 Notification LED Bi-color LED on the right side: Green and Orange
for GSM/WCDMA standby, SMS message, GSM/
WCDMA network status, notification, battery charging
status.
Bi-color LED on the left side: Blue andGreen for
Bluetooth system notification of powered-up and
ready to transmit radio frequency signal, and Wi-Fi
status.
Couldn't find anything else on the LEDs

Sorry to drag up this old post.
My friend dropped my phone (Orange SPV C500) a few days ago on to a tiled floor. The phone didn't appear to be broken or faulty at all at the time. I even managed to use TomTom navigator to go to the airport, but for some reason when I looked at it before I went to sleep, the phone was off. I assumed the battery had gone (even though it should have lasted at least another day). I tried to plug in the mains charger, but the LED showed a red light. I left it plugged in while I slept, but it was the same in the morning. The phone won't power on at all. I've read that this normally happens on a flat battery, but I am pretty sure it still had juice for another day.
I brought a new battery, but to no avail, the phone still shows the red light when plugged into the mains. No light at all when plugged via USB to my computer. The phone won't power on at all.
It must have broke something when it was dropped. But I'm confused as to why it took a few hours to take any effect.
I also notice that even without the battery in the phone, the LED will still light up as red when plugged in to the mains.
I've tried whacking the phone now, but nothing. Anyone have any idea whether it can be fixed?

this is damn scary! Every day more people add on to the "my univ's gone dead after a small drop" community :?
When my univ was brand new, a friend of mine dropped it from a coffee bar table 3 feet high, and i still heave a sigh! Cant believe nothing happened...!
But one thing i guess we all know, its a "drop" away to kiss our device good bye :roll:
hope you get it back up and running m8! look around the forums, there are lots of breakdown-solutions threads...
cheers,
San
nice work afhstingray
do you think it was a baterry problem.
i have often used my battery till tit just ran out, from what i read in the post it seems to be a bad practice. anyway to turn off the phone
i doubt it was a battery problem as i've been using it until now without problems. (i didnt get a replacement as soon as i got back cos im waiting for this unit to get a bit scruffy before i get it replaced)
i had this once on my c500 as well, but taking out the battery for an hour did the trick. so i dont think the problem is related.
i've dropped my universal quite a few times already and im happy to say other than a few annoying dings on the metal plate with the orange logo, its working fine. and 2 of the drops were pretty bad ones too, i thought for sure the screen would die or crack. guess i got lucky and it hit the floor at an angle not too critical
total stab in the dark but maybe a broken connection on charging circuit? that could be why phone was ok then battery died and its now unable to charge?

wouldnt it have worked if it was plugged into the AC then?
Well my Exec was dropped onto concrete at the petrol station whilst I was trying to sort out TomTom and fill up my Yamaha R6 bike at the same time :roll:
No problems, just a couple of case marks.
I guess multitasking should be left to the ladies and computers :lol:

[Q] Nexus 4 Red Light Indication

Hello, forum
I dropped my Nexus 4 in water. I got a replacement battery to fix it, but it seems the motherboard was screwed too.
Initially, when I connected the charger after drying and cleaning the phone, I was getting a blinking red light. After a while (before battery replacement), it became a static red light. Finally, just before battery replacement, I got a red light for a second before nothingness.
After replacing the battery, there was no light. I then cleaned the motherboard with isopropyl alcohol. After some cleaning, I started getting a solid red light even with the fresh battery.
My questions are:
1. Is there are particular error notification system through the red light?
2. Is it possible that I have fixed my motherboard (just need to charge the phone now), or have I also screwed up the new battery?
Please help.
Regards
Raptor
Jumping in on your question
Similar question here.
I'm getting a red light only when the phone is charging and the screen is off. I was in PA last week and it was super cold and i noticed some slight condensation on my phone, other than that, no water or other damage.
The red light occurs on usb charging, wall charging, and on my qi charger, but again, only when the screen is off, the red light pops up.

[Q] Nexus 7 dead?

I was on my computer when i remembered i has something written in my tablet's notes that was important. I took it out of my bag and noticed it wouldn't turn on, it was out of battery (hadn't touched it for about a week). I just plugged it in the proper asus charger and put it down and went straight back on my computer.
I decide to check on it after 2 hours thinking it would be near or fully charged. I pick it up and noticed it was on a blank back lit screen. I unplugged it and then the screen turned straight off. Wondering if it didn't charge at all i re-plugged it in. There was no google logo (rooted), instead it turn on with a lit black screen and off and repeating a few times and then small thin artifact pixels run across the screen (red, blue and yellowy colours) and then stay at a black lit screen like when i first picked it up. I had just noticed a small buzzing sound while this was happening and still does so when stuck at the screen. I'm pretty sure it was buzzing when i had found it.
I redid what i had done (unplug, replug) and watch to see if it did the same thing. It did. I tried to power it off while it was at the black screen and it did, but then it would turn back on and etc. Same if i tried to enter boot loader or any key combinations.
I've tried disconnecting the battery and reconnecting and same effect (tried it without battery attached also)
I have a feeling it is dead now and i have no other ideas (checked many forums but got nothing).
Any help would be appreciated.

It's surely hardware failure, have take some humidity or something like that?
Try press power for 60 seconds, if you wont see any Google logo there's some hardware failure you need to RMA ( http://en.wikipedia.org/wiki/Return_merchandise_authorization )
found the fix
I found away to fix my nexus 7. You could be right how it might have a minor hardware fault, live in australia in the high hot tropics (high humidity). I decide just to plug it into my computer usb charger instead of the proper charger since it had a lower max amp output. Against my ear, a much fainter buzzing is still heard but this time, there was nothing. No power, no back lit black screen, just a very faint buzzing. Decided to let it sit just to see what happens. After an hour or so, i decided to press the power button and noticed there was a battery charging signal. To my delight, I'm sure it was in working order now so i powered it on and oh how relieved i was.
I determined that my device might have had a small hardware fault that made it draw to much power from the 2 amp original charger and thus why the tablet could not boot up properly (from battery depletion). Either that or my charger could be bugged to. But the thing is, since it charged to slow from the usb, i plugged in the proper charger and it worked fine. Just have to try not deplete my battery i guess.
Thanks.

[Q] S5 balck screen after dropped in water (Phone seem to start)

Hi All,
I dropped my Samsung s5 (rooted) phone in water.
Before it went submerged(not more than couple of seconds) it hit the side of the sink.
I quickly took it out and looked for visible signs of broken screen or any other part. But there were no new marks, I wiped it clean, turned it off, took the battery out and looked for any water, but nowhere I could see any water inside or outside.
I then turned on the phone, It turned on all the way to homes screen , I entered pin and could view regular home tab, then I think after few seconds, screen went black. I turned it off and tried it on again but it never came back. Once in between in all of my attempts of turn off and restart, it showed battery and yellow triangle on top of battery sign.
I have tried to search and it seems like lots of people ended up with similar symptoms in their phone, but none of the solutions suggested have worked for me.
What I have tried is:
1. Leave phone submerged in a pot of uncooked rice for couple of nights
2. Take out battery and press power button for x number of seconds (starting from 10 to onwards of 2 minutes)
3. leave batter out and then try to restart (again time was variable from few minutes to several hours)
4. Soft hit on power button,
5. I might have overlooked writing a solution here but I wonder if there is any that was suggested that I have not tried.
Initially when this happened, I connected it to charging cable and red light would start blinking(where as it should stay solid red while being charged).
Anyways, now phone screen is dark. I can use adb shell to view the content on the phone which means OS is till intact and I am 100% sure that phone is working as intended. As the notification lights blink when I get an email if phone is on etc.
Its an expansive phone and hope some one can shed light on how to revive the dead screen?
Thanks
Sorry to hear that! It really sucks. Was the charging port loose or opened when dropped in the sink?
I know the blinking red light, instead of the solid red light, when charger is connected indicates a problem with charging. This can be caused when there is little water in or around the charging board or the motherboard and charger is connected.
If you don't see any signs of water damage (pink/red indicators instead of white), i'd say back up all your files and everything else through ADB, wipe the phone clean, in case you find somewhere to service or in case it gets worse and you can't access your files any more.
Chat with a Samsung rep online too, and see what your options are. Sometimes they repair it for ~$70, off warranty, and with that they might even swap the motherboard and other pieces too if needed and you only paid 70 or whatever they offer.
Thanks for reply, now charging port was shut...and after couple of days now charging happens ok, I have a solid green light when I connect charger.
So I am guessing you are thinking that either screen is gone or something else and therefore no possible way to fix this?

[Q] Nexus 4 do not turn on after LCD/Display crashed

Hello guys!
I've dropped my nexus 4 and the LCD crashed completly. Then i bought a new LCD (only LCD) and tried to change by myself, but everything went wrong, i couldn't attach it with the glue that they sent me and i saw some cracks on the display.
After the "change", the phone does not turn on anymore, just blink the notification led with red color.
Now i'm thinking to buy the full display (LCD+Display) and try to change it again, i mean, it can't be hard to do, you just have to connect the cables and close (that's what i think).
Is there a way to discover if the full display will bring my phone back to life? :crying:
Thank you!!
Up :crying:

The blinking red LED could indicate a fully discharged battery. Try leaving it on a 2.0 amp charger for a few hours to see if you can get it to boot.

I've tried it but the phone still the same. Maybe it's happening due the display is broken (cracked in the top right). I've installed a new one lcd thinking this could be the problem but now i'm thinking it's the display. Is there any way to test the motherboard and see if it's ok? If i could test the motherboard, i could decide between buy a new complete display (lcd + display) or another phone.
Thanks!
I don't know of any way to test the motherboard without a working display.
Heeyy, i've tried a new one charger, the phone blinked the red light a few minutes and then the screen turned on, but unable to see anything, due the broken display, but² the power button dont do anything, not even to turn the screen off. By this we can conclude that the motherboard is ok, and the problem is the display, right?
I've attached the photo of the screen. The white traces is where the display is "cracked", not really cracked, it's like a kneaded cloth, but it matches the cracks that the screen had.
As a test of the motherboard, let the phone charge with the new charger for a couple of hours. Then, try and power up the phone in fastboot mode, and type "fastboot devices" from a command prompt. Hopefully, the command will return the phone's serial #.
