Nook -completely- unresponsive/truebrick,full battery,unrelated to Rooted Forever scr

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.

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???

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.

Issue with not turning on

I've had my tab 10.1 since august and I rooted it to CM9 around 1month or so ago. (maybe longer!)
Last night I picked it up after getting home (it had been on charge through out the day) and it was off. (normally unplugging the charger turns the screen on)
It also will not respond to the power button at all! I left it off charge over night and tried again this morning but still no success...
Does anyone have any ideas what this might be? (there have been no signs of a power outage/surge in my house while out)
Also should I be worried that If I send it off they won't fix it as its been rooted?Or because should be able to tell till its actually working again, I have nothing to worry about?

I think I read somewhere that while holding the power switch, also hold your finger on the touch screen at the same time, and see if that helps.

thanks I will give this a test when I get home! Any other ideas for trying to solve this?

It's possible that it's the Samsung "Sleep of Death" issue.
Here's the way that I fixed mine: http://forum.xda-developers.com/showthread.php?t=1478361

@PynkFloydd
I was just in the process of trying what your suggested as it sounded promising that others may have had the same issue...
Just as I was putting masking tape over the power button it turned on...I was a little annoyed that I had started your guide and I wanted to finish it but never the less... I got my tablet working again
THANKS!!!

Great to hear! I've recovered a few Android tabs and I've noticed that sometimes it just takes a little luck and a little patience and it comes back from its vacation.

Bricked Le Pro 3 727 (Blue Screen of Death)

Hello friends,
My LeEco Le Pro3 (727) bricked two days ago and I haven't had any luck turning it back on. It was running LineageOS 8.1 latest official build with an unlocked bootloader, Magisk 16.0, TWRP 3.2.1, and OpenGapps ARM64 8.1 nano. Immediately prior to bricking I was setting it up for bluetooth with my car and was trying to run Google Maps through voice command. As I directed Google Maps to take me to a location, the phone froze, the screen got all "fuzzy" and I got the dreaded blue screen of death.
From that point on I have not been able to turn the phone back on. When I press the power button it will vibrate every 5-10 seconds as though it will turn on but it never does. Ive tried everything I can think of to get to work again including:
- Pressing power button for 2 min, 5 mins, 10 mins
- Pressing power button + vol up (recovery) for 2 min, 5 mins, 10 mins
- Pressing power button + vol down (fastboot) for 2 min, 5 mins, 10 mins
- Pressing power button + vol up + vol down (QFIL MODE) -> Installing Qualcomm driver, downloading "FlashOne2.0", flashing all versions of "qfil files" that I could find but still unable to boot up
- Pressing all different button combinations while plugged in to computer/charger
- Using different cords/chargers/usb ports
- Leaving it to charge overnight/full day then trying to boot up
- Leaving it sitting not charging for a full day then trying to boot up
At this point I'm starting to think it might be a hardware issue but who knows..
Any advice/suggestions would be greatly appreciated.
Thank you.

Where did you buy it from.
I don't have much to add here it seems like you have done everything that you could
Let's clear this up no fashboot right.
Only one thing to try hold power down then plug in USB.

My one did the same, the issue was motherboard. You should send it back to repair.

Thank you for the reply.
It was purchased from a local retailer here in the United States through Google Express. Fortunately I should still be able to return it for a full refund but I would rather have a working phone than my money back.
No flashboot either. It's like the phone just decided to quit working one day. Tried holding power while plugging in USB as well and no change.

The conclusion I'm reaching at this point too. I'll see what the return policy.

Well if it will not turn on it is hardware issue you should be able to return it.

That is so strange. The screen going fuzzy like that is indicative of a hardware issue, IMO. I saw that on my laptop once, but that was because I hit the screen too hard. Never seen a BSOD on an Android device before. TIL.
I assume you've already tried an adb logcat. Were you using the original LeEco cable? I heard it has issues since it's not up to spec. 99% hardware failure, but I can't help but think it has something to do with driver communication confusing the device and causing hardware failure (?) if that's even possible.

Just a final update for those curious.
After leaving the phone alone for two days I plugged it into the charger and low and behold it started vibrating and booted up by itself. It was running a Chinese developers editions 720 rom due to the QFIL File I had flashed in my earlier in my attempt to fix it. Battery was drained so I let it charge for a while and everything was fine until I attempted to restart the phone. As the boot animation was loading, I got the blue screen of death for a second time.
I took a quick picture, the phone shut off itself off, and same as before it wouldn't boot again. As other users have suggested it appears to be a hardware issue, likely with the motherboard. Fortunately I was still able to return the phone (purchased through Google Express via a local retailer) and received a full refund. I've since bought another Le Pro3 (727) and hopefully when that one comes in, it won't have any issues.
Thanks to all the users who left suggestions/tips.

You bought the same phone again? :good: You're courageous, lol.

i been experiencing the exact problem like your on my x720, as i boot up the system or enterting the recovery mode the screen go fuzzy on loading screen and shut itself off completly, i can still able access fastboot. As i left it for a while the phone will be able to almost finish the boot then ending it all with a blue screen.
Have anyone found a way to fix this DIY since my phone has past the guarantee plan ?

My Le pro 3 (x720) randomly freezes and boots into BLUE LED? Is it now a trash?

Hello everyone.
I have a strange problem. My leeco le pro 3 x720 randomly freezes, turn itself off and goes to black screen with BLUE LED on.. Then i can press the power button for about 10 seconds and it boots into the system again. But then the other problem is, the phone doesnt search any wifi network because the wifi trigger cannot be activated, it always forces OFF. I sometimes boot a few times and then the wifi comes back but again randomly it boots into BLUE led again.. I have tried a few OREO roms but the problem persists.
What do you think? Is it a software or hardwore problem? Or is it bricked or will be dead soon totally?
Please help me. What can i do for this?

Did you tried a clean flash with formating all partitions? Also you can try a driffrent gaaps package. open gapps nano or pico is recomended.

Same Issue!

I am having the exact same issue.
My x727 was on charge and it rebooted all of a sudden and afterwards stuck on blue LED. I long pressed the power button to restart. After restating it freeze and rebooted into blue LED again. I was able to get into fastboot mode but my phone was not recognized by the computer. I gave up then!
The phone was working perfectly on stock Chinese ROM, with unlocked bootloader and TWRP installled.
ANY SOOLUTIONS?

Sorry guys, the blue light means battery death.
Honestly its not that big a deal, at least its not a dead motherboard. Just order another battery, and you might as well order a lcd screen too. Because you will break the lcd when you attempt to remove it.
To avoid breaking LCD use a heat gun. FYI, The battery will cost about $7 and the LCD is about $14

@tsongming i really dont know how to say but you must be a godgiven present for this forum! You are reaching almost to all topics and replying all the questions! Thank you for this!
Now i tell you and all what happened. I was on Bootleggers august build, wifi trigger still couldnt be activated, means no wifi no bluetoth but the phone stopped going to blue led/black screen. I used like that 1 day cos i needed the phone, i was on data internet not to lose my communication with people. I rebooted the phone a lot of times but the wifi still not came back! So i decided to downgrade to Nougat based rom Paranoid 7.3.5 unoficial by voron00 and from the beggining till now everything works without any problem... ! But this does not mean it wont repeat again!
Since my phone had this problem, i had been checking online other forums, especially this ''wifi cannot be activated'' problem, on most forums (samsung, sony xperia etc.) people commented that it might be a battery issue, it needs to be unplugged and replugged or buying a new battery solved their issues. So thats why i was checking on aliexpress some batteries and i saw your comment here! so am sure it %100 battery issue!
Right now i wont risk and will purchase a battery from china and go to phone shop and ask from my friend to replace it.
But i am not sure which battery would suit my phone %100 and wont repeat the same issue at least in the soon future.. Any help?

Is my Note 4 dead?

Hello dear community,
I'm posting there because I have some doubts about my phone and i'd like some answers from you.
1 month ago, I was charging my phone. When it reached 100% battery, It was fine but the problem is when I was trying to press "power" to turn it on but It didn't want to. So, I removed the battery because I couldn't even turn it off. When I tried to restart it again, it didn't want to. No reaction to the "power" button.
I followed EVERY tips on Google but none worked. I also tried to change my battery but nothing. I tried also to connect it to my computer, it was detected but my phone didn't turn on.
So, I guess my phone is dead unless if there is a solution to make it working? Also before that, my phone was becoming very laggy and when it had a small lag, it was turning off and was rebooting.
Thank you in advance for your answers.

I have mustered some conclusions about your phone based on what you typed:
1st claim: The power button no longer works anymore
•Reason: "... when I was trying to press "power" to turn it on... it didn't want to... When I tried to restart it again, it didn't want to. No reaction to the "power" button."
—Seems like you're gonna have to find another Note 4 and replace its motherboard with the Note 4 whose power button doesn't work anymore after 5 years.
But before spending, I would like you to try this method from a Youtube comment:
"... you'll just have to keep the charger [cable connected] on [your phone] while you take off the battery, and put it back after; then, remove the charger quickly..."
—————
2nd claim: The screen no longer works
•Reason: "I tried also to connect it to my computer, it was detected but my phone didn't turn on."
—If the phone is charged, seeing nothing but blackness, but you still see an emitting LED light on the top-left corner, that's a sign that it still works, just not the screen. So I would suggest that you buy a new screen and replace it with your old one. If you think you can't, then go to a phone repair shop and let others do the repairing.

3rd claim: The motherboard is dead
•Reason: "... before that, my phone was becoming very laggy and when it had a small lag, it was turning off and was rebooting."
—The motherboard might be dead if these are happening, but I don't think this is the right reason unless the first two conclusions are proven to be true. If the first two conclusions are proven to be false, then the motherboard is dead, and you may either buy another Note 4 motherboard or get a new phone.

Thank you for your answer.
To answer you clearly about all the points you clarified, there is no led light appearing when putting it on charge and I also tried the "Youtube comment" but nothing.
So I think, the motherboard is dead as you mentioned. I just don't understand how it died after a charge but as I saw on Google, it's a general problem on Galaxy Note 4, so I think i'm not surprised at all. It's been since 2015 I had it.
Thank you for your time and to have solved my doubts about the death about my phone.

Hello dear community,
I'm posting there because I have some doubts about my phone and i'd like some answers from you.
1 month ago, I was charging my phone. When it reached 100% battery, It was fine but the problem is when I was trying to press "power" to turn it on but It didn't want to. So, I removed the battery because I couldn't even turn it off. When I tried to restart it again, it didn't want to. No reaction to the "power" button.
I followed EVERY tips on Google but none worked. I also tried to change my battery but nothing. I tried also to connect it to my computer, it was detected but my phone didn't turn on.

Put in cold fridge for 30 min without battery, then try to turn it on. If not, try the cardboard method under the emmc chip (search youtube)

Is this a serious thing ? (fridge)

I did the oven trick on my n910t. I left my phone stuck in the grill of my truck when I changed the brakes. I took it for a test drive and ended up running over the phone. Me being a noob at the time didn't know the AT&T Note 4 would not unlock Bootloader for custom roms or custom recoveries. I purchased the AT&T Note and was sorely disappointed there after. Flash 2019 I still have the motherboard for my note that I ran over. I can only get in to go into download mode and only when it was plugged in. I flash custom ROM or custom recovery and it would say would pass but it would just boot loop and boot loop. So I read somewhere where you can put it in the oven for around 5 to 6 minutes at about 200° and that it would settle any of the cracked solder that be around the emmc or anywhere else on the board. So I tried it. I stuck it in two different times at five minutes a piece, pull the board out and let it set for a day. I installed the board just a little while ago and she fired right up. It's amazing

I've recently replaced the motherboard on my N910F with a used one bought from AliExpress. As it's used I've no idea how long it will last but for £30 was worth a try.
It was pretty straightforward replacing the motherboard using one of the tear down guides on YouTube.
