Hi guys,
My tf201 keeps shutting down.
I was using it when suddenly if just shut down and went black dead.
I started it, in several seconds it goes off again. This happens if it is connected to keyboard dock, through USB to computer or not connected at all.
When started to recovery or to system, or even in APX mode as soon as I get into nvflash recovery mode it just shut down in several seconds.
The same for adb or fastboot, I cannot do anything, it just shut off in a second as soon as I get into any mode.
I have got all all my backups and files ready, but my problem is that tf201 keeps shutting down on me and I cannot push any files to it because as soon as I start it shuts down while connected to computer on USB in the middle of transfer.
I wonder if any of the experts here have seen something like this I would really appreciate any suggestions.
I got it back to life!
It was the battery issue!
Just to recapitulate:
It started by shutting down the tablet one day while showing 100% battery.
Would not boot into anything (system, recovery, adb, fastbook even nvflash mode) because it would shut off after several seconds.
I tried to reinstall everything, but I could not finish any process, tablet would shut down in the middle.
I left it connected on the dock hoping it will recharge.
After 2-3 days I tried to start it, it would show red battery screen and shut down immediately. That was something new I have not seen before.
I looked around and have find out that battery is or completely fried or need to get reset.
There is two methods to try.
1. open the tablet and unplug the battery cable, then after a while plug it back and charge.
2. reset by applying paper clip in the little hole on the left side of the tablet below the Micro SD card slot and charge at the same time.
I decided to start with the second method first, since I didn't want to open the tablet.
I plugged the paper clip into the hole and taped it on the body of the tablet with the tape in a way that would apply constant pressure on the clip. I plugged it through the USB into the computer and let charging for about 5-7 hours.
Then I tried to start it into recovery.
Miraculously it worked and battery was showing 35%.
After that point everything wen smooth, I formatted and reinstalled new N 7.1.2] [ KatKiss - Nougatella #036 ] by timduru and it works like new again.
Battery is charging normally and instead of constant 100% is now showing real number that goes down when I use the tablet and up when I charge it.
Looks like the battery needed to be reset by complete discharging and then starting it up by disabling all the controls using the paper clip trick while charging on computer. That started the battery again into a new life.
Hopefully this post will help someone in similar troubles.
Thanks for support guys!
Sincerely

I have a Cingular 3125, working fine for weeks, happened that two days ago, I was charging the phone and transferring files to my computer via Bluetooth, nothing unusual, then it just got frozen, nothing responding, so I just took out the battery to manual reset the device and reinserted it, then tried to turn on the device, but it refuses to boot, no lights at all, also when I attach the phone charger, it doesnt show the usual orange led when charging, but I can feel that the phone gets warmer because the charger is attached and then after a while it gets a bit cooler, just like when it finishes charging, the usual behavior, but again, no lights at all trying to boot it or even attaching the charger, I've tried taking the battery off for hours and nothing also, and I wasnt overclocking the phone... would you say it just died? or maybe someone had same issues and solved it someway? thanks.
try this
OK, I don't remember where I read this, or the exact procedure, but give this a try.
remove the battery, press and hold the red call end key (power key) for 30-45 seconds. insert battery and do a hard reset, IE.. power on holding the 2 top soft keys while powering on the phone.
this method is supposed to clear any mother board issues and reset the phone. It has been a couple of years since I read the procedure so I am not sure if this is the correct way, if it does not work, try the same thing, only try taking the battery out, then put it back in and press and hold the power key for 30 - 45 seconds.
may or may not work, but can't hurt to try.
i had the same problem with startrek which i had bought from eBay
one more advice - try to hold record (notes) and camera buttons and insert an USB cable to your PC, it should enter to Bootloader mode
well, I have dissasembled the whole thing, I havent reached anything, even disconnected the backup battery, nothing, have checked battery with a multimeter and is full loaded... in short, someway the cell phone seems has just died, Erofich, to enter bootloader mode, the phone must turn on, it just doesnt want to start at all, no lights when connecting charger or USB cable... I'm sad because it was working fine with no problems for three months and more sad because it's the end for me to windows cellphones for a long time, I've invested a lot in this phone, accesories, unlocking, and even the same day it died also bought more memory and a neat skin cover and I'm not in mood to invest more in a cell phone so I'll use a spare crappy feature phone.
Thanks for your support.
one last effort
You could try one last thing, this has worked for me with a couple of startreks,
take the phone apart, and take the motherboard out, use a hair dryer to heat the motherboard, don't get crazy with it, but using the hair dryer on the high setting for about 30 to 45 seconds at about 3-5 inches, might revive the phone. (don't heat the battery, just the motherboard)
Put the phone back together while it is still hot (but not so hot that it will burn your fingers) and try to fire it up.
This has worker for me in 3 cases (phones that I bought off eBay that had the same symptoms as you have described)
good luck
big problem!!!!!!!!
I have been struggling to flash (again) the great pro V2 rom, but I always used my VMWare based XP windows version on my Vista laptop. Today I could use a genuine XP Laptop and I could make a connection and start the upgrade!
Sounds good? That's what I thought too, until the upgrade stopped at 70% (and I didn't touch anything), because of a connection error. I followed the text on my PC screen and I finally it started flashing again for a few seconds and then my startrek suddenly restarted, but it stops at the first splash screen! I tried to get my device back to bootloader mode (push 2 soft buttons and start), but no bootloader mode, only the 1st splash.
I solved the problem.
Hey Y'all,
I helped a friend of mine root his NT awhile back, and it was working fine for months. I showed him CM7 running off of the SD card and he liked it, so I set it up for him on Friday. I did a factory restore on the NT, and he reentered his BN account info. I then booted off the SD card and everything was working fine as I could tell.
He brought it to me this morning and it won't charge. The "n" is always green when plugged up to the wall and it never goes orange to indicate it is charging. But when I attempt to power it on, it is always displaying the low power message and says to plug in the charger.
What I have tried:
-I removed the SD card, and it still won't charge... (not that it would matter).
-I have 3 chargers and my own NT. When I plug a charger up to my NT it works fine and the "n" goes to orange. But when I plug the same charger into my friends NT, the "n" is green and I can't get past the low batter warning.
-I have had my friends NT connected to a wall charger for about 3 hours this morning and I still can't get it to boot.
Any ideas on what might be wrong and how to fix it?
Thanks for your time.
I found this thread and tried both of the suggestions and my friends NT still won't charge or boot.

The same thing happened to my wife's nook this evening. I think the battery is completely run down, but won't receive a charge for some reason. Her charger showed green also.
I tried, removing and reinserting the SD card and also holding power for 20 seconds. I finally was able to hold down the power and the N button down for about 20 seconds. This did the trick. It showed that the battery was too low to turn on. After about 10 minutes, it booted.
Hmm, I get the battery is too low to power on every time I hold down the power button and the "n" is always green on the charger.
strandedinar, did you have the power cord hooked up when you held the power button and "n" button down for 20 seconds?
So connecting the STOCK charger and the STOCK cable and leaving it alone for an hour or so isn't doing the trick? That's really the most that many of us have had to do... No "n" button needed either.

Yes. The nook was plugged in and the "n" was green. The Nook wouldn't power on - My wife was convinced it was my fault for rooting it...
I left it plugged in like that for 20 minutes, but nothing happened when I tried to start it. The charging light was green. I finally tried the power + N button trick and then I received the notice that the power was too low to turn on. This was the first time I received this message. After this, the color of the charging light changed from green to red/orange and I could tell that it was receiving the charge. After 10-15, it power on and has worked normally since.
I tried every thing I could think of and google and nothing worked. I took it to BandN yesterday. They thought it was a typical issue that they see a lot of, but after 3 folks at the store couldn't figure it out, they called 1800 support. Support said it was a bad usb port and swapped it out for a refurbished model.
I still think I could have fixed it, but after a couple of days my friend was getting antsy for it.
Thanks for all of the responses.

How did you do that? I was trying to hold the buttons and never got anything.
My NT has no juice to boot, but when I plug in a power cord (stock), plugged into stock power charger, it tries to boot up. Power indicator does turn orange, but then it runs out of power once it starts booting and turns off. After a few second it turns back on, and repeats same cycle again. It never boots to the point where it can actually sleep, seems that boot-up process takes more energy than charges could give it.
Try charging it from your computer. Just as suggestion not sure if it will help.

Hello Galets, did you manage to finally charge your Nook? I have the same problem as you have - when stock cable and charger are plugged in - device tries to boot and screen shows up but due to lack of power in accum it turns off and in a few seconds the cycle repeats.
I hardly understand - how it is possible that having mains power plugged it - there is not enough energy to charge and do other necessary things...
---------------
UPDATE: problem solved. In order to solve it, I had to disassemble the tablet and unplug the screen cord, then I put the power cable in, battery charged up for about an hour or so, then I plugged screen cord back in and turned it on without a problem. The down side of early charge attempts is that tablet decided that I had 10 failed boots and it reset my previously rooted device. Now I have fresh and clean stock 1.4.2 version.

how did you unplug the screen cord? I've looked up how to take apart the nook, but I'm not sure which one would the the screen cord. Did you follow a tutorial somewhere, or was it easy to figure out once you opened it up?

ACL3, check this link: http://www.ifixit.com/Guide/Installing+Nook+Tablet+Display/11148/1.
I did not really follow the guide. I was looking for first two bolts to unscrew. The rest was quite simple but challenging - i don't usually disassemble things.
I did not pull out any of the buttons or battery from where they are and simply unplugged their connectors too - you will see 3 small foam rubber black box-like pieces (in step 9 they only marked one of them). There are plastic connectors under foam rubber pieces.
Be careful not to short-circuit anything with metallic tools.
On the attached image I marked the screen connector. I unplugged it by gently hooking it with two small screwdrivers. When putting it back I gently pressed it until I heard a click. And make sure those small slots on connector match with corresponding ones on motherboard.
Also, when finishing assembly I ran into a small problem with corner flap (which covers sdcard) - it did not want to smoothly slide in and out. So, pull it off completely and after putting plastic cover in place and screwing last two bolts, put it back - some small help of small screwdriver will be needed.
Hope my explanation was helpful

thanks, looks cool. I've never taken anything apart before and I'm afraid of short circuiting something. I think I might try this.
I wanted to share this experience in case it happens to anyone else. I rooted my nook tablet and installed CM and everything worked great. This is a full install to the OS, not running from SD card at all, no SD card present. However, the battery ran low into the red zone and shut down the tablet. I plugged it in and it tried to start up without me even hitting the power button, as if it was in deep sleep and tried to wake up when it saw power. But, because it didn't have enough juice it would only get to the CWM menu screen and it would power cycle and start over again. I did the power/volume reset but that wouldn't shut down the tablet completely because every time I would plug it in it would try to restart again. Finally I was able to get it to run long enough to get to the CWM recovery menu and quickly choose power down option at which point it began charging without trying to restart. After I let it charge for an hour it reached about 60% at which point it started fine and has been fine since. It's a reminder to not let the battery drain too low because I'm not sure if this was a one time thing or if it is going to happen every time the battery drains low.
I had the same issue, my solution was to keep powering it on until it drained the battery completely. Finally I got a warning message that the batter charge was too low to power up. At this point you can plug it into the charger and it won't try to auto start.
I have a similar (maybe the same issue). But I have an additional one, because I am using a SD card. 2 Things to care about:
1. Use a powerful enough charger and just plug it in, it might boot cycle automatically, but at some point it will boot correctly... For me the charger of my Motorola Defy (850mA) with the original Nook charging cable works.
2. Leave the SD card removed while booting (I just "click" on it, so it is removed but still "connected" to the case), otherwise I also just get never-ending boot cycles for some reason - but maybe this SD card is "partially bootable" for some reason (though I never used it as a bootable SD card...)
So, I have a Nook Tablet 8gb that's stuck in a boot loop. I was using it last night to read, decided to go to bed and plugged it into the charger. Upon plugging the tablet in, it powered off, tried to boot up again, and then powered off again. It's now stuck in a boot loop (only shows the 'n' screen for 1 second), and it only does this when plugged into the charger or my laptop. When I remove it from the usb cable, it doesn't even power on at all.
I tried calling the Barnes and Noble customer support, but being that my NT is 1.5 years old, it's now out of warranty and they apparently can't do anything for me. The guy tried walking me through some troubleshooting steps and ended up telling me that it's a hardware problem. Before I toss it out, I decided to check here.
I have looked at other posts and seen similar issues that have been posted about, but seeing as how my NT won't even turn on without being plugged into the cable, none of the fixes on here seem to have worked. I did try downloading the repart.img onto a sd card but I was still unable to get my NT to reset to factory settings.
I'm at a loss at what to do with this paperweight, and I can assure anyone reading this, that I will never own a Nook again because of the horrible customer support, and the fact that the one I had only lasted me 1.5 years. Please help if you can, thanks!
Ok, update to my NT situation... (FYI, this appears to be a h/w issue with my battery vice an Android OS issue)
Just to clarify, I'll give a little more information. I've been doing research all day on my problem, and I feel like I need to specify some things in case anyone else has a similar situation going on. After reading some other posts online, this is what the problem initially appeared to be...
My nook tablet's battery drained all the way to 0% before I plugged it in. After plugging it into the cable (via pc or wall outlet), the tablet would power on, show the 'n' screen for approx 1 second, and then power off. After about 5 seconds, it would power on again, show the 'n' screen, and power off again. Basically it was just stuck in a boot loop and did not seem to be charging up at all even though the indication on the cable showed it should have been charging. When I would unplug the nook from the cable, it would not turn on at all.
Possible solution #1... I read somewhere in a couple different posts that it could be just a battery issue caused by me letting it drain all the way down. Some people resolved their issues by removing the back from their tablets, unplugging the battery for 10 seconds, plugging it back in and then letting the tablet charge. (Removing the back and messing with your tablet's hardware will void the warranty!!!) After watching a couple videos about how to access the battery and remove it, I decided to unplug mine and give it a shot.
Results so far.... After plugging my battery back in, my NT has stopped going into the boot loop. I'm now getting the message to let it charge for 15 minutes and then try to power it on again. This is at least a different screen than the boot loop I was seeing, so some success... hoping in about half an hour I'll have even more success. I will update again when I see something different... crossing my fingers!!!
Yep, unplugging my battery did stop the boot loop, and my NT is now charging. I was able to turn it back on and it's now at the stock setup screen.
Even though no-one replied to the post, I'd still like to thank the Android gurus that do post here and help individuals resolve their problems. It seems like I'm always learning something new when I check out the forums. Please keep up the great work!
Now time to root and have some more fun!!!
As the title suggests I have an old Z2 tablet that has been an absolute work horse for many years. I was using it one night and the Android OS prompted me that the device hadn't been rebooted in 28 days. So after I was done using it for the night I rebooted it. Only, it didn't reboot it just stayed off. I tinkered with it for a while and got it to show the Sony logo but then it just went dark again. The device is rooted and I have TWRP on it. So when I got it to turn on again I booted it into the TWRP recovery. I proceeded to clear the cache and also attempted to make a current backup. However, the backup would fail after running for several minutes. I decided to try backing up to an external OTG USB drive but the device needed to be rebooted to detect that the OTG USB drive was attached. So from TWRP I selected "reboot recovery".
Unfortunately that was the last time it worked. The screen will not come at all. When I hold volume+ and power it vibrates 3 times but still doesn't boot. I plugged it into the charger even though the battery charge last showed at 85%, but with the cable connected the charge light doesn't even come on. I tried plugging it into my computer but it doesn't detect the device has been connects and adb devices doesn't show anything in the list.
I read on a forum to try drying it out with a hair dryer and while the device hasn't ever gotten wet it has been humid here so I figured what the heck. Unfortunately that also hasn't resolved the issue.
Pretty much everything I've tried hasn't worked. Even the red reset button under the top panel just causes it to vibrate 3 times.
The device has been in this state for a week now. I was hoping maybe the battery would die and then I could recharge it, but since it still vibrates 3 times I'm guessing the battery still has a charge.
One thought I had is that maybe the internal storage is either dead or corrupted.
At this point I'm wondering if the device is a lost cause and I should just let it rest in peace or if there's any other solution. Even if there was a way to factory reset it from it's current state that would be better than having it be a paper weight.
Any suggestions beyond what I've already tried would be greatly appreciated. And, yes, I may look into seeing if I can get it serviced however there's definitely no warranty and I don't really want to poor money into it since it's probably time for an upgrade anyway.
Why is my phone vibrating 3 times and won't turn on? - Sony Xperia Z5
When I try to turn my phone on it just vibrates 3 times and does nothing after that, just wondering what the problem could be?? - Sony Xperia Z5

The device vibrated 3 times, that's good, then it is off.
"Sony writes: This is how you force the device to turn off:
Press and hold the power button and the volume (+) button simultaneously until the device vibrates three times."
Did you try to put the device into flash mode after that? I think only a complete flash will bring the device back to life.
