Before I start I know how touchy people are about searching forums and the wiki etc... but I already have!
Ok so, I tried to flash a new ROM to my phone last night, I have done it before without problems however this time I was having trouble getting the phone to connect to my laptop (I run Windows 7). Both USPL and HSPL wouldn't work (in fact active sync wouldn't even recognise it).
So I went to bed, woke up and... My phone didn't work at all
I spent ages trying to get it too work, I tried putting it into bootloader, but nothing happened, I tried getting it to Hard reset, but nothing happened. (By nothing happens i mean the screen doesn't turn on).
The only sign of life i get from it is the little vibration that usually occurs after the 'smart mobility' screen appears. Except this is delayed by about 10 seconds from after pressing the Power button.
The delay makes me think that there is something else wrong with the phone other then the screen...
Please help!!
Oh and I am sorry for the essay... I only just realised how long and rambling it is haaa.
UPDATE: right it just connected to activesync but still nothing on the screen, is there any way of checking for definite that the screen is broke before I fork out for a new one? There is astill the massive delay between turning the phone on and getting the little vibration...
Try removing battery overnight, then re-inserting. Then try to get to bootloader or hard reset
how exactly did you manage to brick it? did you flash the rom in question with uspl, or do u generally have hard spl installed? i dont know but it looks like the bootloader is somehow broken ...
Ok I will try doing that, thank you for helping
And no, I didnt get as far as flashing the ROM because active sync never recognised the phone in Bootlaoder. I usually use USPL.
Did you fix it? and if so how?
I have very similar issues with my HD right now. Screen went black, bought a new LCD and still the same problem. Oddly enough the only way I can get the screen to come on is to take the battery out and set both battery and phone body in my window sill for half an hour or so. It is cold here right now and they are both pretty cool to the touch when I take them out. Put it back together and tada! Screen comes on. I dunno what the deal is also, don't know if its the battery or phone being cold that makes it work again??? I am going to try and figure it out.. Try it on yours it may help
Hello all, I'm curious to hear your thoughts and advice.
My nook is completely unresponsive. It is not stuck at rooted forever.
In fact this has nothing with a root attempt/reset/restore/power on.
I had done a a fresh reset/root with touchnooter about four months ago and was happily and smoothly reading for about two months. I then got busy and put the nook down, did not touch or use for about another two months. I tried to use it about a week ago but found that it had run out of battery in sleep after the two months of disuse (not surprising). I put it on charge overnight and everything booted right and functioned well once it turned on, except that the battery indicator in the statusbar showed a "?" and the battery info in system info showed 100% "unknown". After alot of fruitless research I put it down with the intention of reset/restore/root when I had the time.
I just picked it up this morning and was faced with the expected "Press then button below to wake up your NOOK" screen. But when I pressed the "n" button nothing happened. Obviously holding the "n" did nothing as well.
I tried to power it off and on- nothing
holding power for 20- nothing
power for 30- nothing
8 failed boots- nothing
left right- nothing
left right power-nothing
random pushing and holding of power- nothing
all these with mem card in and out- nothing
all these plugged usb- nothing
all these pugged ac- nothing
I let it charge some more- nothing
None of the buttons do anything, the screen stays inevitably at the " press the n button to wake" screen. no activity whatsoever except that when It is plugged in, the green light shows. NO ORANGE LIGHT... it is fully charged by both usb and ac.
It is not detected at all by windows anywhere.
In Linux- lsusb, bklid, and df -h yield nothing. My nook might as well be the invisible stupid ereader.
I did not drop it, sumbmerge it, perform magic around it... It has been sitting on a shelf doing nothing.
To repeat, the only thing my nook does is light up green when plugged.
It is unchangeably stuck on poe's face...
If this isn't true brick, I don't know what is.
I'm exhausted. Any ideas? I appreciate the help.
Best,
Thomas
i don't know. i just know my dog ate mine and i'm now in the market for a new screen, so if you don't get it working sell me the unit and get some money for yourself to purchase a new one =D
or you could google the disassembly instructions and try unplugging the battery, not very hard to do. could be of .. some help perhaps?
I would definitely take you up on your offer, but i'm still under warranty.
However, I would still like to have my original, and figure out what is going on and why it happened.
Ideas?
Thank you.
similar problem were solved
Hi! I might have read about similar problem solved on USB host mode here http://forum.xda-developers.com/showpost.php?p=23475998&postcount=131
That's it, thanks so much.
if it help
if it helps let them know in the tread that you had same problem. they are wondering whether it is due to host mode
[N2E]: After automatic update to 1.1, Nook Touch Screen absolutely DEAD--Nothing Work
THIS WAS A POST FROM ANOTHER SITE AS TO MY PROBLEM:
I was reading on my N2E last night. I put it down for about 30 minutes and when I came back it was displaying the default "Authors" screensaver (I had switched to the Nature photos) and asking to slide to unlock. I thought, "Oh, the new software update must have downloaded and installed. I'll check it out." To my shock, the touch screen was completely unresponsive--no amount of swiping would unlock from the screen saver. I let it set for a while longer thinking perhaps the softare update was not yet finished. No such luck.
As a result of the new update, my NOOK is now completly DEAD! I tried powering off, but couldn't do that because you are asked to confirm power off on the touchscreen, which no longer works. So, I looked online and tried the soft reset/reboot by holding down the "Home" or "n" button and then pressing the power button for several seconds. Great--it started rebooting...and came right back to the "authors" screen saver and asking to swipe to unlock. I tried this rebooting process several times, always with the same result: back to screeensaver mode with completely unresponsive touchscreen.
So, looked at the online technical troubleshooting discussion and helps and decided to try a downloaded manual install of the software update. Plugged my NOOK into my computer and it recognized it. So, I downloaded the manualo software update and dragged and dropped it onto the NOOK as directed and sure enough, it started to reboot itself. I thought, "whew, maybe this will fix it". NOPE--came right back to the locked screensaver, with no mention of attempting to update software, and the touchscreen is still dead. (By the way, all of this was done initially with the NOOK showing about 94% charged, so it was not a battery issue.)
Reconnected the NOOK to my computer and the software update file was gone from its home directory, which implies it did something with it. So, I tried repeatedly to install the software update manually, always with the same result: NOOK comes back to locked default "authors" screensaver wtih a dead touchscreen.
Looked online for B&N technical support again saw that others had this problem (though only found a couple references). Found the instructions to do a factory reset and reluctantly tried that, desparate to make my NOOK work again, but frustrated that if it did I would have to rebuild everyting on it and download my 400+ B&N book library all over again. But, guess what, factory reset just comes up to the "Welcome to your all-new NOOK" screen (sounds like progress), BUT the touchscreen is STILL dead, so I can't hit the "Next" button onscreen to proceed with setting up my factory-reset NOOK. Tried rebooting again (as this seems to be the only solution offered in the online tech support) and now it just keeps coming back to the "Welcome to your all-new NOOK" screen with a dead touchscreen keeping me from doing anything.
So, now I am taking it back to my local B&N store in hopes they will exchange it for a new NOOK.
I really want to see a feature to disable automatic updates in the future. I specifically didn't download and manually install when the update came out, figuring I'd wait for the automatic download to give time to B&N to work out the bugs and perhaps issue a patch (as they have done in the past for the N1E). Instead I get no warning about the automatic download (happens while I am reading and set the NOOK aside for 30 minutes), and then the update KILLS my NOOK.
I am not a satisfied NOOK customer at this point.
MY POST: (from the that site)
Not Sure how to do this post or whatever, but I was happy until the update and everything that happened to you is the same with me. This is the first post that describes what happened to me. I'm out of warranty and refuse (and can't) to buy another one of these. If their updates can do this, I'm not sure I want to sink another $100 into the shareholders pockets. I'd really like to know if anyone knows what may be wrong with it.
In addition to what was already mentioned, I took the battery out several times(which seems intimidating but very easy but voids the warranty) and took it completely apart cleaning the screen very well with water and another time a glass cleaner. I tried rooting also. Not sure of what to do now. It seems software related due to working fine until the update. Still at the "Welcome to your all-new NOOK" screen with unresponsive screen. I wasn't sure if the last sentence from B&N was a personal message to me welcoming me to the "new" state of the my nook.
Thanks for any help from anyone.
Thanks.
Identical problem.... and no fix..
It is a shame you got no solution for this. and the worst, you are not the only one... it happened exactly the same with my Nook ST....
Hopeless...

The factory restore does not actually fix every possible problem with your Nook.
If your Nook responds at all, try to boot it up on an SD card like ClockworkMod or noogie.
At least that way you can see what is happening.
The partitioning might have become corrupted which the "factory restore" does not touch.
If no response with anything, try disconnecting the battery.
You might also try booting over USB using the techniques in rooting the new white glow.
Hello I was wondering if I'm just screwed I bought 2 nook simple touch, one for me and one for a present to my mother for her birthday on march 16. I bought them at best buy for $40 a piece on January 30. I used mine and was perfect but when I tried to set up my mom it wouldn't load the license agreement, always got stuck or reboot or something, so I loaded cwm on an sd card just to play around, tested on my nook and was fine, then put it on my moms nook booted once then I didn't press anything and turn it off then I load the image but when I tried to boot again it got stuck on the load screen and wont do anything, no reset sequence will work with the sd card on or off the other nook boots with this sd card. at the end I exchanged with my mom she is happy with her nook an I have a useless unit do you think they will exchange it I didn't rooted it or did anything to it but has the n cwm splash on screen forever. I'm in Costa Rica right now and wont return home until May do you think I'll might be able to exchange it or should I just try to repair it.
I'm glad that your mother got the working one!
You say that that one will boot on your CWM SD card, but yours won't?
It may be hard to get your unit exchanged with a conspicuous screen on it, even if it's not your fault.
When you plug it into your desktop is there any indication of a new USB device found?
If it's charged and no amount of the power button gets a reaction, I'd open it up.
any news???
Hi endor43, same problem here, have been able to find any solution?

There are times when a Nook gets in a mode where it won't accept a charge.
Opening it up and disconnecting the battery for a minute might fix this.

When this worked for you did the light turn orange right when you plugged the battery back in? I just took the battery out, plugged the nook into a charger, and with it plugged in plugged the battery back in and the light stays green the whole time yet I'm not able to use the nook at all.
My nook second generation is not responding to my touch I tried everything to get it to work and I eventually got it to completely power of what if it does not work when I turn it on what should I do
It could be power/battery problems.
Check to see if it makes itself known when the USB is plugged in.
If it reacts at all, that's an indication of life.
I originally posted this over on the MotorolaDefy.com forums, but it seems to be pretty dead, so I'm going to quote over my post and then update it with what I have tried since.
Generally, I don't like to post on forums asking for assistance, I know how many repeat problems you guys probably have to read, but I don't know what else to do at this point. I've had my Defy running Cyanogen Mod for months, and earlier today I noticed the Wifi wasn't connecting properly, so I rebooted it. Lo and behold, it became stuck at the Cyanogen Mod screen, it might have something to do with me installing BusyBox earlier in the day. In anycase, I followed this guide: (link removed, since this is my first post - not really important since I figured out the McGyver trick) to attempt to fix the problem. Now the phone won't boot at all, I can't even get to the boot loader screen. RSD Lite still recognizes the phone when it is plugged in, and the white light still comes on when it is charging. I'm scared ****less to take any further actions without input from somebody with more experience. I have to head out to work now, but I wanted to post this before I left. If anybody has a solution to my problem (and I'd be grateful), then I'll attempt it in a few hours. All I'm trying to do is reset it to factory default so that I may reload Cyanogen Mod onto it. The phone worked beautifully up until this point. I am on Telus and I live in Canada, if that is at all relevant. Thanks!

So, since then, I've gotten my screen working again, I had to use the McGyver trick (gypsy-rigged usb cable to the contacts of the battery) to jump start the bootloader, and I managed to flash in the Froyo 2.2, 3.4.2-179 sbf. It ran! Thank god in heaven! But... it got stuck at the T-Mobile logo consistently. Next, I tried flashing in Froyo 2.2, 3.4.2-177 sbf. Again, it miraculously boots but it hangs at the pulsing Motorola logo.
That brings me to where I am currently, which is; I have absolutely no idea what to do next. All I want is to get my Defy up and running with a stable version of Cyanogen Mod again. It ran flawlessly before and I loved my phone, best phone I've ever had. I'm stressing out pretty hard, and I've tried all I can find on the internet. Please, XDA, help me!
Edit: I doubt this is relevant, but more information can't hurt, so I'll add that my Defy is one of the newer ones with the red-lense.
Have you remembered to wipe data and cache (factory reset) in stock recovery?^^
If you still have that data from when you ran cm7, and you're trying to boot stock, it could prevent you from booting! Happened to me once and i just couldn't see what the problem was! Really annoying.
That sounds like it could be the issue, you're supposed to be able to do that by holding volume down while powering it up, correct? Because that doesn't seem to do anything for me.
Not working? Strange. Hold volume down before pressing power button and keep it pressed untill you se a warning triangle. Then hit both volume keys to enter the recovery. Still not working?
Sorry, I should have been more specific, I can get to the little Android guy and exclamation mark, but when I touch the bottom right corner, no menu comes up. I've never actually had to access the stock recovery before, Cyanogen made it so simple. Am I supposed to be doing something other than tapping the screen?
Update: Google is my friend. I found a suggestion that I hit the up and down volume buttons at the same time, and the menu appeared! I wiped the cache and all the use data (important stuff is on a memory card anyway, I'll just have to get my contacts back). I did get an error, reading: "E:Can't mount CACHE:recovery/log". I rebooted the system regardless and IT BOOTED!
Thanks for pointing me down the right path, I owe you and this forum a great debt!
I'm now going to charge this bad boy back to full before I attempt to reload Cyanogen. (Since having wires hang out the back is starting to get old.)
I managed to short out something doing the McGyver trick, because I'm getting the question mark battery problem. Hopefully it's an issue with the battery and not the phone. I'm incredibly disappointed, the phone is fairly new and I loved it, and don't have the money to drop replacing it since there are more urgent things to attend to. I guess all I can do is hope for the best.
As of now, it won't even boot. I'm going to try the battery in a friends phone and his in mine to try to identify the problem.

I always recommend THIS solution over the McGyver method. Defy is farely often owned phone, so guys... first of all, don't let the battery drain completely; second - if this happens, don't rush into jump starting it. Try all other options first, ask somebody to recharge your battery and don't do McGyver, unless you've run out of other options.
Now try connecting your phone to the wall charger and don't try to start it for at least an hour. I've had plenty of cases when brand new Defy, Defy+ or Atrix, that have never been rooted, leave alone jump started, show the battery with "?" in it when battery drains completely and takes some thirty minutes or so of charging until the phone is able to start again.
Good luck, my friend!

TL;DR: Any way to fix/flash a Nexus 7 that reports it's in APX mode to Windows yet, that won't do anything else?
Backstory: I've had a 2012 Nexus 7 32gb since the day it came out (Oct 2012 or so?). Worked great for a year, loved it! Had AOKP on it, unlocked/rooted, used tons of apps, never a single problem. And then one day while I was using it to play music while charging it, out of the blue, it hard shut off while it was running, rebooted and shut off during boot and... never turned on again. Wouldn't indicate a charge, wouldn't turn on, couldn't get it to respond to any power or volume key presses, nothing.
I called Asus, and they agreed it needed to be repaired. I sent it to them, they sent me back the same unit, repaired, and said they swapped the mainboard out in the repair notes. Worked great, except the device was completely wiped, relocked, unrooted, and they removed my nice Stenheil screen protector.
I was without it long enough that I got used to not having it. Since it was completly back to stock, I decided instead that I would sell it when I found a good buyer (friend, etc), and buy the new 2013 Nexus 7 instead. I found a friend who wanted it a few days ago.
Today's Issue: I charged it over night last night so it was on a full charge this AM. I saw that I was still running 4.3 on it (hadn't really used it since I got it back in November), so I did the factory/official "OTA" update to 4.4.2 this AM. Went flawless, no issues, booted up fine. I updated all the apps on it, also worked fine.
I then decided to do a Factory Reset on it, (Thru Backup/Reset IN android, NOT Recovery). I went thru the confirmations/warnings, and then it said "Shutting Down..." and, it shut down. I let it sit for a few minutes, expecting it to boot back up (it never did). I tried to turn it on, nothing. I tried ALL combinations of power + volume, + charging cable in/out, etc. Everything possible, trust me, I scoured the web for new combinations and timing ,etc. No matter what, I never got ANYTHING on the display, no charging indicator, no recovery or bootloader, nothing. It's like the display is dead. The battery was fully charged this AM after being charged overnight so I know the battery wasn't even close to low. It's like it's completely dead no matter what I do.
I then tried to hook it up to my PC, which is setup for ADB etc, couldn't see it in ADB. In Device Manager though, it's showing as being in APX mode? So I tried holding power down for 10 seconds with it connected, and it DOES disconnect from windows, and a few seconds later, it shows up again, again in APX mode. Nothing ever appears on the display. Holding VOL down or all three buttons while plugging into PC never changes anything, no matter what, it ALWAYS shows in APX mode.
From what I'm reading online, this is a sign that the bootloader is missing or corrupt, and, that there isn't a fix for that unless you first backed up your crypto "blob" using Flatline (which I didn't even know about till today). I'm hoping that maybe what I've read is out of date? Is there perhaps a way to fix or flash this yet?
The whole thing makes little sense. All I did is update it, then reset it, all officially supported/normal things, on a bone stock tablet. It seems more like they didn't ACTUALLY fix it the first time it went back to them....
Help? AFAIK the tablet is now out of warranty. I just want to sell it and get the 2013 model! The tablet is in perfect shape, it's been used with a screen protector and case since day 1 - not a single scratch on the screen or case. :crying:
i'll take the silence to mean I'm screwed, right? :crying:
I don't know how, but it seems your bootloader is gone. (corrupted sector on the nand,maybe)
You can't do much without the proper blobs.
If I were you, would try to send it back to Asus. They are the only ones who can repair it.
Wow I can't believe it's been two months, but, I still have this tablet, still not working, Asus won't fix it for a reasonable price... anything changed on this in the last two months?
It seems like it should be possible to do something... maybe I'm just optimistic.
I want a 2013 Nexus 7 but it's hard to pull the trigger knowing my very lightly used gen1 model failed twice now.
There is no way to produce an universal blob and device specific blob creation is working so there is little to no reasons for further development.
You could fit a new motherboard 32gb ones are expensive but the 16gb are a lot cheaper
Programming is a race between engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.
They're readily available on eBay - $35 for a used 16GB motherboard, and $50 for a 32GB board. That's how I fixed my APX bricked N7...
Whoever stumbles across my late entry, if the N7 won't boot after empty battery, no button combinations work and PC shows only APX mode - take off the back housing (it's pretty easy to do) and disconnect and reconnect the battery cable, this let me boot it up immediately...
(my N7 however was plugged over night to charge before I attempted this unplug but actually didn't show up the charging indicator and wasn't bootable, surprisingly it was charged already half when I finally could boot it up)
Sent from my OnePlus5T using XDA Labs
Apparently it is possible without having done the backup first, at least for some people.

Hi everybody,
What Happened:
My phone has suddenly become totally unresponsive. I have been using it most of the day, it was sitting at around 70% the time that it happened, but it is now a totally black screen. I had just taken it out of my pocket and it was suddenly like this.
The only idea I could come up with as to why this happened is that I charged it off of a JBL Charge 2 last night. I'm not sure if that may have messed with the battery, but I do find it odd that it's totally unresponsive while plugged in.
I was running android 7.1.1 DP2, with the ElementalX kernel 4.0 I believe. I was also rooted with SuperSU. What's really odd is that I hadn't done anything new recently besides install uTorrent and VLC media player. Otherwise, my routine has not changed one bit. Up to when the phone actually died, I hadn't even used either of these new apps the entire day.
What I've Tried:
I have tried plugging it in via AC, via USB, I've tried booting into recovery or fastboot, but there is zero response from the phone. No indicators on the screen, no LED blinks, no vibrations, nothing.
What I'll Try:
If anyone has any experience with this happening, I could use some advice. Otherwise I'm just going to wait it out, consider an RMA I guess. However, my device did have the bootloader unlocked and was rooted, so.... I hope it comes back by itself.
My advice is to keep it plugged in, or see if there is a response on the computer perhaps on fastboot, upon using the bootloader keys. I haven't had this, just a few suggestions. Good luck!
PS: A RMA will probably be needed, there are much more experienced people around here. Sure you may get replies later.
