[Q] Can't power on HD2 with WP7 after power off

Successfully upgraded HD2 phone to Windows Phone 7 (thanks DFT and everybody else) but after a power off (using the power button) I can't power on the phone without first removing and refitting the battery. Then the phone will power on normally. Any ideas?

try doing a factory reset in setting > about. it will look like the phone has shut off, but let it sit, then the phone will successfully reset and power on automatically. DOIT.

I've also noticed that after the "Goodbye" screen shows up and then the screen completely turns off the device itself stays on for a couple secs... Sometimes it turns off completely right away..
I noticed that while the is phone charging... when you normally turn it off the charging light turns off along with the phone... then it starts charging again for like 2secs light turns off and the phone turns back on since MAGLDR doesnt let it charge while its off... if you get one im trying to say

Just trying to paraphrase for you....
When you turn off the phone, be patient. It seems to have turned off but is really on for a short time after the screen goes dark. Give it a second

Long Press to Power On?

Anyone else have an issue with having to long press the power button 20+sec after powering down for more than a few minutes to get it to turn on?
Just returned an 8gb unit for screen lift and wanting a bigger storage capacity. Know its hard to get a perfect unit and I have found a perfect screen but now every time I power down I have to long press the power button to turn it on. My other unit turned on within a few seconds. Normal?

I've had that happen on 3 of them already. I've just learned accept it as normal behavior. Some days it powers on quickly some days i have to power it by holding the power button for 20 seconds.

How often do you power down your device? I probably never, unless have to.
Btw, I don't need ours the button for that long

Every Android device I have had expects a long press to power on.
Nexus 7 is one of the faster - mine takes about 4 seconds.
I expect the delay is to keep a momentary press from accidentally turning it on (pocket call).

I was panicked yesterday. After powered down, I could not turned it on.
Usually it will take a few seconds, but yesterday was about 20 seconds.
So I guess it is "normal".
I will no longer freaking out next time

Happens to me too. Every time it takes about 10-20 secs to power on. Generally I switch it off at night!

Yes there are times when I just press for 2-3 seconds and its powers up. Sometimes, it just doesn't power up even after 10 second... But I got used to this issue and I just keep trying again and again.
This is something Google should fix

Just bought one today and have this issue, about 10-15 seconds. Weird randomness. The first boot it only needed a few seconds. When you're travelling like I am atm its good to be able to power off if i dont know when i can charge it the next time. I wonder if its hardware or software. Nice device anyhow, the screen is so so but at this price i wouldnt expect better.

I had the same issue and thought my battery died, but the weird part is if I plug it into the oem charger it wouldn't show anything either. Don't know if that's normal or not.

Same here, I purchased it, held the power for a few seconds to power it on and it worked. After a few days I decided to turn it on one day and it wouldn't power on til I googled the answer LOL

mine booted up super quick at first, started loading it up with apps, and after my 2nd full battery discharge i noticed that it took 10-20 seconds to turn on. i have a C8OK, very very slight left side lift (not enough to be a bother) and i had super minor flicker at low levels of brightness. Funny thing, i got LUX brightness app with the free 25$ and use the "sub zero" brightness setting, i like to save battery and keep it dim, this has eliminated ALL flicker for me. i was thinking it was hardware doing this as other tegra devices had flicker, but now i think it is something with droid settings/software. i would suggest all those with flicker to try this app.

Are you talking about boot up time or time it takes holding the power button before the device switches on
For switching on it should only ever maximum take 10-15secs of holding power as holding power for 10secs simulates a battery pull

[Q] Nexus 7-Horizontal lines & Static Noise

I was using my Nexus 7, browsing the web, and the battery dies, so i go and get my charger, plug it into a USB extender, and then into the Wall Charger, it began to charge then when i unpluged it by mistake it made a static noise, (like the old TV snow, that static-y noise, I dont know if it came from the speakers or not though) and on the screen was grey(ish) horizontal lines, & really tiny colorful horizontal lines, that were moving up and down. Now it will not charge or turn on even if pluged in via the wall charger. Help?

Horizontal lines in portrait mode? I've been getting that on my Nexus 7 all the time , specially when the battery was lot or I was surfing the internet. Unplugged, discharging or low battery charging. I will try and get a replacement for dead pixels though.
Mine didn't make any noise though :/

Is it anything like this problem I've been having? http://forum.xda-developers.com/showthread.php?t=1973953

Sweet, I'm hoping the static I have gets fixed by the update!!
EDIT: after mashing the update key a few more times and getting the OTA, this problem seems to have gone away.

Same thing happened to me tonight.
Heard the low battery sound thought it was gnex but realized I had it charging . Went to see nexus 7 and saw it was at 0 so quickly plugged in charger but was too late. When I plugged in charged it was dark screen but then became slightly lit. When I tried to turn on it wouldn't and after holding power button it would bring about the static screen. I eventually got to Google screen and thought it was fixed. I thought it would boot normally and charge, when I glanced at it a minute later saw it was showing static.
Made a video here https://www.youtube.com/watch?v=72bU5-0IsM4&feature=youtube_gdata_player
This was made after reaching Google screen second time and I was going to stop recording because it booted normally and no static appeared. However at 49 seconds you will see that it does. After restarting again and then booting normally I shut it off before trying to get the static again and it charged normally and now its at 73% charged and running fine. I was scared tho but from what I searched it seems to happen when battery dies out

[Q] Nexus 10 (16Gb) completely bricked

- Steps to reproduce the problem.
I have seen a couple of other freeze ups from time to time, rather randomly, in various apps, not just Chrome.
In this case, I clicked the "All Apps" button in the lower right corner, and it froze.
- What happened.
The system froze, and then the screen went black. Now I am completely unable to restart the tablet. I does not matter how long I hold down the power button, either alone or combined with the volume up/down, it remains bricked. While connected to USB, it will show the battery charging icon in the middle of screen every 10 seconds (stays on for ~3 seconds) while I'm holding down the power button.
As of now the tablet is basically dead.
The tablet was running Android 4.2.
Does anyone have any ideas?

Power with volume up and down at the same time til you hit fast boot?

I know this will sound stupid, but are you sure you have battery?

Or try to hold the power button for about 20 seconds until N10 vibrates. That's it.

Keep it plugged in to the wall for a few hours and try again
edit: Emphasis on wall

How good are you with technology?

it may be worth reading this and possibly popping out the battery just to see if that helps.

did you resolve this issue? i just started having it. i know i was running out of battery and then my n10 wouldnt boot past the x screen after a restart. i left it plugged in but i dont know if it was charging. now it won't turn on and i get the same issue you have. i have it charging over night but i dont think it is going to help =(

Thanks for replying but after me thinking it was broken for 2 months it suddenly turned on on its own last night!
Not really sure what was wrong to begin with but when it turned on I had 0% charge for a few hours, really strange.

Same issue for me on 32Gb model.
I had a flicker screen once last week and today it doesn't boot up. I connected it for an hour but all I get is the fully charged battery icon when I press the power button, sometimes with a flicker screen or red/blue/green dots all over the place. It doesn't vibrate, it's not recognized by my Windows 8 computer.
I bought it through the eBay US deals and it sucks cause I'm in Europe...:crying:

Call +18553926398 from Skype. It is a Samsung Nexus Repair Center. From Skype it's free of charge line. I had problem with battery in my nexus 10 32gb. I had to send it to US on my cost. I spend on it (from Poland to the US) about 70euro(by UPS), from the US to Poland about $50 (by DHL). But Nexus came back repaired on warranty and it took about 1 week only. It easy and It worth to try. Important: Samsung Repair Center can send your fixed Nexus only to the US (to the US it's for free), so I used MyUS.com for 'a proxy' to send it to Poland (and this part cost about $50).

[q] tablet froze. Won't turn on.

Hello. I've had nexus for a few weeks now. Tonight i was surfing the Web and the screen started blinking on and off rapidly. It finally shut off. Now it will not boot. I tryed getting into the bootloader by holding volume up and down and power. I get nothing. If I plug it into the charger... The battery icon comes on the screen but that's it. If my nexus fried? Is there anything else I can do?

Screen blinking rapidly on and off? I'd call Google. I'm sure they would send out a replacement.

Yeah I called them. I they are sending a replacement. I have to pretty much pay for a new one untill they get the old one back.
This really sucks. What could this be?

I've had my nexus freeze while using chrome a few times. All I do is hold the power button until it reboots. Has worked for every time.
The flickering screen does not seem normal. Glad google is giving you a replacement.

I've had the exact same problem as OP. I was browsing in Chrome when the backlight started flickering. Wearing headphones but with no sound, I was able to hear faint static that correlated with the darkness of the screen (when the screen was dim mid-flicker, noise was produced). I had it set to a specific brightness setting, so I switched to automatic using the drop-down settings menu. The problem persisted. I did not exit Chrome. I tapped the power button which gave a normal enough looking fade out. After about 5 seconds I tapped the power button again to power the device on. The Chrome screen I had been looking at when I powered the screen off flashed briefly on my screen accompanied by a bit of static and a slight pop, and the device went black. I have not gotten a response from the device since except for, like OP, when the device is plugged into the wall. Then I only get a battery icon with a lightning bolt for 1 second every time I push the power button.
After calling the warranty information number, Google is sending me a replacement device. They do not make you pay $400 (in my case, as I had the 16Gb) but authorize a payment of that amount so that if you do not return the device within 21 days they are not left high and dry. Seems reasonable to me.
Anyway, just adding my experience with this issue to the forum. OP is not the only one to get this symptom!

I just got this same issue. Was reading my news feeds on Google Reader, it seemingly froze up for a few seconds, then the screen started flickering when touched, and finally went black. Device is non-responsive except when plugged in, where it'll display the battery icon for a few seconds.
I do not know if this is related, but I was also having the charging glitch where it would power down with "0% battery" when plugged in or unplugged seemingly at random, and the long wake-up issue.
Now I am trying to get the device awake enough to be recognized by my pc so i can adb backup my data, but so far I am getting nowhere T.T
