[Q] Help! My Nook is dead?

Hi,
mi n2e only with 1 week and has got frozen in the middle of a book. It doesn't respond. Soft reset doesn't work. Battery was about 50%.
I have disassembled it and try a lot of things, remove battery, connect to supply without battery... but the screen is in the same page of the book. There is no way to turn off screen.
Now with the nook connected to supply the led indicator is off and my computer doesn't detect it. This morning I got the light turned red (charging perhaps???) In this situation when I pushed button to turn off, the red changed to green for 2-3 seconds and then turned red again. And my computer detected it.
But now the light indicator is off again.
This is a gift from a friend in Usa. I live in Spain, so there is no warranty and for this reason I've tried to repair myself.
Any help, please? I'm desperate with it. I can't understand it fails in only 1 week.
Thanks.

> Soft reset doesn't work.
What do you mean by "doesn't work". It happened to me that my touch screen stucked but when I pressed "power off" button for a long time (e.g. 15 s) my nook rebooted and then if was OK.
But in you case whole system is stucked (no menu after pressing "n"), right?

Right. Whole system is out. Anything works... Now when I plug to power, there is no light on (led is off).

Hi Esfinge
Did you find a solution?
Same thing happened to me, I'm in South Africa, so can't take it back to B&N.
Got it brand new, charged it, connected to wi-fi, registered, loaded a book via Caliber (on Mac), switched off wi-fi.
The next time I picked it up it had the message that the unit is switched off and that
you have to power it up by pressing the power button on the back.
Tried removing the battery, did not help at all, also holding power button for 20 sec.
If I plug it into power the light goes green and then orange after a couple of seconds, if I connect it to a computer I can access the files on the nook.

Dude, it's a e-ink screen..
When powered down it still retains its last image, it wont go blank unless told to do so.

That doesn't make sense, a powered down N2 will not mount the sdcard on your pc when connected via usb.
So if you're able to access the Nook partition while the N2 is still showing its "powered down" screen, you're in some serious trouble, as that would indicate the N2 is powered on and running, but not communicating with the e-Ink screen

This seems to be the case, worked perfectly and then suddenly not, I might be sitting with a 'Friday' model.... anyone know where I can get a new screen?

Screen is black blank, hasnt came back since it first shut off after the first or second reboot on the first try restoring it to 1.4.3. The Screen was working fine before I used it everyday then i wanted to switch roms from phirmod 7.1 to NookieJoyOS it worked but the wifey didnt like it. She wanted her original nook color back. So I went back to original stock rom and then i started having problems. At first i though i had formatted something wrong in cw3.0.2.8. Above I was stating scenarios in threads i was reading on what possibly happened.

I recently got an NST screen/digitizer for ~$40US on eBay, it took 5minutes to replace it.

[Q] Mt4G won't boot AT ALL

I went out for a while with my battery at 20%, when I came back it had drained out. I put it to charge, but when I tried to switch it back on, it refused to boot. On a normal power button press, it would vibrate 3 times and then the red notification light would start blinking. Same thing with power + volume_up. If I press power + volume_down, it would vibrate 5 times and the green notification light would stay lit. Nothing comes on the screen, whatsoever.
I was rooted with S=off, and was using the Operation Inferno ROM (which I have been using comfortably for the past month or so).
I did try some stuff with ADB, such as using it to reboot into bootloader and recovery (same 3 vibrate + red notification light), pushed the Operation Inferno ROM again to the sdcard and tried to restore the ROM from that location (for which I got adb: unable to open file /sdcard/backup.zip).
I haven't yet gotten around to downloading and installing the factory image some have suggested for the eMMC issue (PD15IMG.ZIP) but I wanted additional opinions considering most people with an eMMC issue have been able to open HBOOT at least.

When the phone doesn't power on, neither ADB nor fastboot will help you. There is no device on the other side, so all your attempts went to the drain, and it was expected. Nothing to do with eMMC issue or anything else. Your phone just doesn't power on.
Put your phone to charge, if the light turns orange - just leave it to charge until it's green, then disconnect and try to power on.
If the light doesn't turn orange, or it doesn't power on even after charging - remove the battery for 10 min, press Power button for 1/2 min, release the button, reinsert the battery, put to charge. And again, let it charge before you try to turn it on.

I did charge it earlier (for about half an hour or so) and the orange light does come, but it didn't boot after that either.
I'll just give it a try by charging it through the night and see.

I think a key thing is to take out your battery for 10 min, as Jack_R1 suggested. Then proceed with the charging.

Still doesn't work. I dissembled it and kept it like that for quite some time, then put everything back and charged it for hours. Still the same issue happening during boot.

Connect the phone to USB, powered off, see if the PC recognizes "QHSUSB_DLOAD" device. Try to power it on, see if it happens.
If it happens - it means your primary bootloader is screwed, in another words - no repair (actually, repair is theoretically possible, but no guide, no information and no sources exist for MT4G).

When its plugged in, its recognised by the ADB (even when powered off), and I can do some basic commands (mentioned in the first post). When I power it on the same thing happens as when it wasn't plugged into USB (ie, the vibration and the blinking LED).
I'm also worried about water damage, since a very tiny amount did come on it as I was sweating profusely. Although the indicators in the battery tray and on the battery itself don't signal damage (they're completely white) I've just decided to try and keep it opened up in a bowl of rice, just in case, until someone is able to come out with some idea.
As I'm in India, taking it to T-Mobile is not an option. If nothing works out, I might take it to HTC and see if they can help out.

[Q] Fixed (not blinking) red light after changing battery

Hi everyone,
a friend of mine's Nexus 4 has this strange behavior.
It went into water for about 1 second: unfortunately, she was working far from home and needed to keep the phone on for working reasons, I know and told her that the best would have been to switch it off and put in a bag of rice.
In any case, after few minutes where she was not able to listen to the people speaking, and the same on the other side (she was not listened), she kept the phone in a pocket and under the sun, and suddenly everything went fine: probably some water in the audio jack made the phone think the earplugs were plugged, and then this was fixed.
In the rest of the day everything was working, and we thought that, thanks to the hot day and the phone under the sun, the humidity has dried up.
At night when she came back home, she switched the phone off and put in the rice for the night.
The day after, she tried to switch the phone on, and nothing happend.
Screen black, no signals.
After reading something on the internet, she plugged the charger, and kept power+volume down buttons pushed: after some time, the red light appears, just one fast blink and then dark again.
So, we ordered a replacement battery (I have already substituted a Nexus 4 battery of another friend of mine), which arrived yesterday. I proceeded with the substitution, everything went fine (and I noticed that the internal water detectors are still perfect white, only the one in the sim tray is pink), but when I plugged the usb charger, again nothing happened. This time, holding power+volume down made the red light appear and stay solid, no blinking, no disappearing, until I unplug the phone, at that moment it disappears.
I let her charge the phone for the whole night, but still the same issue this morning.
What can the problem be?
It sounds strange to me that at first the phone worked and then it stopped at the first switch off (and I think that she powered off and on the phone right after the incident, and was still working) :-\
And I'm not able to understand the red light behavior...can someone help please?
Many many thanks :-[

[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?
