[Q] Can't turn on - Nexus One Q&A, Help & Troubleshooting

Hi guys, so my Nexus One won't turn on. The power button is shagged and has been for a long time. But I've always managed to get around this.
Now I have just recently flashed the latest MIUI-US rom to my phone and the battery went flat today.
I can't get the phone to turn on due to faulty power button. I have tried the battery pull technique that I used successfully on CM7. I'm not sure at all whether it is to do with the rom or the kernal at all but the battery pull just won't work anymore! Help!

Try pulling the SIM and SD also...

If I do it like that, I won't be able to use my phone once it's on

Ok, I'll be more specific.
Try pulling and reinserting your SIM, SD and battery...

I've tried, but still no luck. I've bought a Galaxy S II now, so waiting for that to arrive. So glad to not have to worry about a stupid power button anymore

[Q] Power button broken, battery trick is not working.

sorry if there is an answer somewhere, couldn't find it.
my power button on the N1 broke and yestarday I had to turn it off. the battery trick (plug in the phone, take out and re-insert the battery a couple off times) worked once before but now the phone simply stays off.
warrenty is not an option anymore for me.
Is there any another way to turn the phone on without using the power button?
thanks in advance
Edit: just in case, my N1 is an SLCD model and its running 2.3.4.
Wow, I'm having the same problem and was about to make a thread like this.
Running CM7, the phone crashed on me last night and I had to turn it off. I tried the battery trick, but it's never worked for me. The few times I've had to turn the phone off, I was lucky and the power button worked after mashing it for a couple of minutes, but now it's completely dead.
I'm under warranty, but right now I'm without a phone and and need it back up ASAP..
(Mine is also the SLCD model, if it makes a difference.)
Edit: Managed to mash the button to life once again; My phone is back. I think I need to give HTC a call.
Try pulling the SIM and SD, as well as the battery, and re-inserting them all...
The other option - I read a post by a guy whose power button was stuck in the closed position, and he had to open the phone and separate the contacts to get the phone to start...
Also if you are anything into some DIY repair work, there is always a spare part for this http://shop.ebay.com/i.html?_kw=nexus one power flex
With the right tools, it shouldn't be to much of a problem replacing this part.

[Q] Help! Bricked phone... :/

Here is where I stand: my Captivate stops at the At&t screen. I can charge the battery, but that is it.
Problem: when I take out the battery and reinsert, the phone automatically turns on without press of the power button. I am not sure how to get it to stay off with the battery in. So because of that doing any of the combinations to get to the download mode so I can flash stock is not working.
I have also tried a make shift jig, and that hasn't worked either. If anyone else has
encountered this problem and fixed it let be know! I need to be able to have my phone off when I try the key combinations etc. So please help!!! Thanks!

On that jig did u put some tape between wire and your fingers? Are you sure you are connecting the correct pings? A key combo that might work is:
1)take out the battery, sim and SD
2) connect the usb to your phone and press the key combo (if on I897 bootloaders Vol +-)
3)stick in battery
4)you should have download mode
Yes, with the jig there is tape and I made sure it was with the correct pings.
With the key combination, all it does is restart my phone which gets me nowhere.
Is there a way to insert the battery so the phone doesn't automatically turn on?
Thing is if the jig is done right it supposed to work regardless. =/
Hmm, that is what I thought. I will keep working on it. If need be I will have to order one already made.
Just ordered one from MobileTechVideos.com, should be in Wed. I will let you know if it works.
something that just occured to me. Did you use 1/4 or 1/2 watt resistors?
Got the ordered jib in and it worked perfectly! I am relieved, now I can fix my Captivate.

[Q] Broken Power Switch

Greetings.
Today the power switch from my Note stopped working.
I found a website that will replace it for an original Samsung one, but I would like to ask if anyone has a better alternative here on the US.
This is the one I got:
http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-note-power-button-repair/
Also, it is weird that now that the power button doesn't work at all, I have to take out the battery to "turn off" the phone. But when I put the battery back on, the phone turns itself on. Is that normal behavior?
Thank you in advance.
if the phone is working as usual, then instead of removing the battery to switch the phone off, use any widget from the playstore to power off the phone. this way it will power off fine. may be its because the power button is messed up.
After 14 days of having the power switch in a nonworking state, today I woke up, and lo and behold, the damn switch started the work again.
Now I can turn off the phone normally, everything is normal now.
I didn't do anything special, nothing at all.
Before, I couldn't turn off the phone even with apps like QuickOff, thats allows the phone to reboot, turn off and etc, so I had to take the battery out every time.
I have no explanation.
You got lucky there :thumbup:

So, I think it is just because the power button gets sticky. I was having a similar problem, except that it was working intermittently; sometimes it would turn the phone off, sometimes it would bring up the shutdown screen; and sometimes it would work like it was supposed to. Probably yours started working when whatever was making it stick got dislodged. What I did was just press the button REAALLLY hard for a while while the battery was out. It's been about 24 hours and I haven't had any problems yet, fingers crossed. Another guy in a different thread just wiggled it around. Probably if you take the whole board off you could remove the power button and reinstall it or something, though it seems no one has had to go that far yet. Anyway, if anyone else runs into this problem, just mess around with the button until it starts working again. Though, as always, if you break it, its not my fault.

[Q] Power button broken, another way to boot the phone?

As the title reads I am quite sure that the power button is broke in some way or another on my HTC Desire C. I believe this since the phone is off and I cannot start it up with the power button. The reason I think that it is the power button that is broken and not something else is that when I plug it into the charger the battery shows up on the screen as always and says its charging.
Now, I wont be able to have it in for service in a couple of months and I really need the phone right now.
I could probably live with a broken power button if I just got it to boot up, which is the big problem here! I have googled for answers and found some saying for example that to charge it while popping out/in the battery in different ways will make it automatically boot up but nothing seems to work.
Is there any way to power it up without using the power button?
(Probably a good thing to say that I am not using any kind of custom rom or whatever, everything is stock)
Would be really awesome if someone could help!

Is my note dead?

Hello all, something weird happened to my phone today and I would please like some help to get it back working.
So as I was in the ebay application when the phone suddenly froze. I left it for a minute hoping that it will unfreeze but it didn't. So I long pressed the power button in order to do a hard reset. The phone shut down and then its started booting but it got stuck at the Samsung logo with the yellow triangle. I thought that was weird as it never did this before, so I long pressed the power button in order to do another hard reset. But since then, the phone is dead.
It cannot start, when I plug it in the charger the battery icon doesn't show, and I cannot get into recovery or download mode
I have tried removing the battery/simcard/sd card but nothing seemed to work. The phone was running Nightowl's Marshmallow rom.
About a month ago I changed the charging port flex cable with a cheap one off ebay. Could that be the culprit? It seemed to work fine though.
Does this mean the end of the long life of my device or is there any hope of reviving it back?
Thanks a lot in advance
Hello. It is probably a hardware problem. Take it to service center to check the usb micro port, pmc or emmc. Or just leave it alone for some time and try to boot it again.
