Running TnT lite v5. Normal boot was fine except for an error "System UIDs Inconsistent". I wanted to fix that but whenever I try to boot into recovery it hangs on the Viewsonic screen after the 2nd line of text (something like "Booting recovery kernel image"). I do not have an external card in it right now, but I have tried booting from one with no success.
Any ideas?
Thanks
Another bit of information, "lsusb" does not show the tablet.
happened to me to. put in the gtab-cwm-v08.tntlite5 before i was gonna run the 5.0 tntlite. what i´m gonna do now?
I found this thread:
http://forum.xda-developers.com/archive/index.php/t-934595.html
Looks like there is a process that involves opening the device up. Does anyone know if this actually works? Here's the process outlined in the thread:
1. Disassemble the tablet. Remove the four rubber stoppers on the bottom of the tablet (put them aside). Next, unscrew the screws under them (keep those too). Next we need to get the back half of the tablet off. Put the tablet face down on a piece of paper or another protective material. Gently work one corner of the tablet until the two halves are slightly separated, then use something thin like a business card to keep them slightly parted. You can then use something thin and strong, like a plastic gift card to zip around the edges and break the seal. Prying will only damage your plastics.
2. Disconnect the battery lead (a flat connector with multicolored wires, probably held down with tape. Look near the battery.)
3. Connect the device via USB.
4. Short (connect) the four contacts circled in the photo. (A smallish square of tinfoil works well for this. Be careful.)
5. Press the power button for 2-3 seconds and release.
6. Disconnect the tinfoil shorting tool.
7. The APX device should be detected on your computer.
8. NVFlash a working bootloader.
9. Disconnect the AC adapter.
10. Reconnect your battery.
11. Reconnect the power until your device is charged.
You have pushed a wrong set of buttons ... you need to hold the "volume Down" botton and then power it up so you can restore it with NVFLASH, you will have a BLACK screen... no need to opend it ... if you see a message on the screen it's means you only boot in recovery (Volume up + power)
tried this...nothing different. still frozen. any other ideas?

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.
Hi, guys.
Inert/dead/hung Nooks can sometimes be resurrected by this insanely easy trick.
First, so you’ll understand what’s going on:
All the Nook Tablet’s buttons are really soft buttons. Even the Power button is really a soft button: All it does is communicate with the OS.
That’s worth stressing: the Nook power button is not a simple mechanical on/off switch, but a switch that sends a signal to tell the operating system to power off.
It’s sort of like the power button on the front of most PCs. The real on/off button is usually on the back of the PC (and is absent on a Nook). A PC’s front panel button, like the Nook’s power button, communicates with the OS, sending a shutdown signal.
Why is this important? Many times (in my experience) when a nook appears dead or even bricked --- dark screen, totally unresponsive to all external input --- it’s not actually dead, but hung in a software loop.
If the Nook had a true power-off switch, you could depower the hardware, and do a cold boot. That would kill the software loop, and the system would start from scratch, rebooting normally.
But without a true power-off switch, there’s no way to stop the loop, which will run --- conceivably many weeks --- before the Nook battery runs flat. Even then, a slow decline of battery power may allow the Nook to suspend itself --- in the loop --- meaning that when you recharge, the loop resumes looping, and you still have a dead nook.
But you can force a fast battery shutdown.
Wrap your nook in airtight plastic --- a 1gal freezer bag is about perfect. Squeeze out as much air as possible. Put the Nook into your refrigerator for 3-4 hours. The cold will cause the battery to lose charge very quickly.
After 3-4 hours, remove the Nook from the fridge, but leave it in the sealed plastic. Place it someplace at normal room temperature, where air can circulate freely around the Nook. (A cookie sheet or something similar is great.)
The plastic will ensure that any condensation that happens will happen harmlessly on the OUTSIDE of the bag, where it can’t hurt the Nook.
Wait until the plastic is dry and the Nook feels room temperature.
Remove the Nook. Recharge for 15 minutes. This will put back just enough charge to get your Nook bootable, without resurrecting any suspended processes, if any.
Turn on (leaving the nook plugged in). With luck, your Nook will now do a normal power-on full boot. Finish recharging normally.
I’ve done this four times on my Nook tablet. Works like a charm each time.
(I know this tip sounds sketchy, but it’s real. Google me, Fred Langa, if you wish: I’ve been a professional technology writer for 30 years. Of course, your mileage may vary; I can make no guarantees that this will always work. But the logic is sound, and it's worked for me.)
For me, pressing power and volume+ together for a few seconds (forcing the device to power down, I think) usually does the trick. Not sure how the battery would like the fridge method...
wow, i've been reading your stuff for many years ! its 'great' to have you as part of the nook community. really !
.
( secret ) i would like to crack this nook open and solder on a real 'power switch' and 'power led' . . .

If the OS is truely hung, the power+volume won't work, alas.

Chilling (not freezing) the battery has no long-lasting effect. Many MFGs actually recommend storing uninstalled batteries in a fridge.
Wouldn't it be a lot faster to just open the case and unplug the battery?

The issue most people have isn't a software boot loop problem. Dead devices are usually caused from not understanding how to flash ROMs. Deleted internal partitions and such. It's always essential to learn exactly what you need to do before you do it.

Yes, I agree, most bricks are the result of a bad flash. However, that is not always the case.
I have a Nook Tab that I rooted way back in 2011 with the NookZergy method. It is my daughter and wife's tablet, so I did not do anything else. I only rooted so I could put Amazon App Store and the Play Store on it instead of buying over-priced apps through the B&N Store.
After a number of months the power button stopped working completely. I thought it was a hardware failure, so I added an on-screen re-boot button widget.
A few days ago, the unit appeared to be off, yet I could not get it to turn on via that "normal" ways (plugging it in and letting is charge for a bit had always resurrected it in the past). After reading this thread, I opened up the unit, unplugged the battery cable, waited 5 minutes or so, and plugged it back in. The Nook booted right up on its own...
The point of the OP was to completely drain the battery to give an opportunity for a hard re-boot. I was just making a point that, instead of taking hours to do this, it can be done in a matter of minutes if you have a t-10 driver bit...
There is an easier method .
JUST HOLD THE POWER BUTTON FOR 30 - 60 SECONDS .
holding for few seconds will tell OS . Holding for >30s will shutdown by force . No need of volume button,etc.
End of story .
Do not follow OP instructions . Crazy method . Dangerous . If put in a freezer there will be condensation for sure (even a little air trapped inside cover will condense), not to mention potenial cracks or solder troubles inside due to thermal contraction. As a last resort if all else fails maybe.
When my screen went blank , I connected via USB and used ADB to reboot it . But then I learnt to just hold Power button for a long time.

You should go back and re-read my post. My power button doesn't do anything... I have used ADB reboot when the unit was locked up with the screen on... I never thought to try it with the screen off. It is probably faster for me to open the back and pull the battery cable than it is for me to refresh my memory on ADB anyway!
Alternative Low battery in Ap fastboot fix
Tested and confirmed to work on Verizon Motorola Droid RAZR XT912
I softbricked my Verizon Motorola DROID RAZR XT912 while testing some stuff out when it got bootloops. I hard reset it by holding the volume down and power button for thirty seconds. when it restarted it got the all black screen with white letters saying Boot Failure in Ap Fastboot mode. I could not flash the factory Rom back on it to make it operational again cause my battery was below 50% charged. So here is what I did.
I used a 600ma charger cut the end off and then cut the wire coating back exposing 3/16 of wire. With charger unplugged I attached the red to the + and the black wire to the - terminal being extremely careful not to touch anything else in there causing it to arc and possibly causing damage. I recommend that you download the IFIXIT APP in the market to a tablet or use their website so you can get the instructions on the removal of the back plate without breaking or cracking it. Once removed you can use the torx screwdriver to remove the negative screw. It has a washer too I just placed the wire neatly under there making sure not have any individual wire sticking out everywhere and re-tightened it. Then done the same to the positive side.
Now that you have done this you should very carefully flip it over taking extreme care as to not have the wire break or fall out. I placed mine over the edge of the table so I could inspect it before plugging it up. If all is good plug it up then hit volume up and down plus the power button at the same time. When done correctly the Boot Mode Selection Menu will show. Use volume down to scroll the list to AP Fastboot highlight it select by pressing volume up. Usually it'll go straight there cause it's bricked and in bootfailure. The RAZR will now say BATTERY OK. Run RSD Lite and install your Fastboot files with RSD5.7
Fast boot file listed below is for the verizon edition.
ICS 4.0.4
VRZ_XT912_6.7.2-180_DHD-16_M4-31_1FF.xml
After it fully installs turn device off and carefully remove everything paying close attention not to touch the cut wires to anything and also be very careful with your torx screwdriver. Then snap the back cover on and power it back on. Worked twice for me since it keeps soft bricking every time cause of Bootloader being locked.
Update, Thanks to whirleyes and the app called Bootmenu which allows you to partition some space for a second system (dual boot) i'ts located on the market. I'm able to flash without any problems now.
If you find this helpful give thanks.
Hey, I recently tried using AnTuTu to benchmark my (non-converted) Optimus G and the phone just shut off on me. From there I couldn't get it to turn back on, it will only boot loop the charging logo when I plug it in. I'm pretty sure the partition tables are all messed up.
Anyway, I'm attempting to completely flash back to stock with LGNPST and I've tried every combination of installing drivers and I've tried going to "Tools>Load Ports" (can't remember exactly what the menu said, I'm using a mac now). However I plug the phone in, however, it isn't recognized, I've tried opening the program with it plugged in in download mode, and plugging it in when the program was running in download mode.
Any suggestions?
Thanks a bunch!
EDIT: Probably worth noting that recovery gets stuck at a black screen and no adb access. Can't flash a ROM using fastboot flash zip, I get the following error "FAILED (remote: partition table doesn't exist)", that being said I have access to the bootloader and fastboot.
Gotta take the battery out. Use a t5 torx for the bottom 2 screws, then starting by the sim card slot work an old credit card all the way around the edges popping off the little plastic clips. Gently lift off the back. The camera will still be attached to the back so be careful. Gently remove the camera from the back panel of the phone (not the ribbon cable!) then remove the 2 tiny phillips screws holding down the battery connector, pop it up, wait a few seconds and reassemble. Be careful when putting the camera back in the housing, and put the top of the back panel back in first. Sounds like a lot but pretty easy if you take your time.

Make sure you run LGNPST with admin rights.
I was asked to by my cousin to see if I could help him as he was having a problem with his S3 today, by coincidence a friend also rang me about his S3 giving him problem. When I got hold of both phones I found that they have identical issues. Both phones are not rooted and more than a year old so out of warranty.Here are their problems.
1. Turn on - it just loops at the splash screen.
2. Enter recovery - It just flashes the android figure and goes back to the loop.
3. Enter download mode - only as far as vol up and it goes back to loop.
4. Plug into wall charger - It shows the gray battery icon with static circle, at times it just flashes the charging icon.
5. Remove battery and insert the phone boots into the loop.
So there is no way to wipe or flash with Odin, I remember I had fixed my Note 1 with the charging issue which is the charging port. So i guess it could be the same problem,
THE FIX - There is a flat horizontal plate at the charging port which after repeated pluging in and pulling out usb it somehow touches the bottom. couple with dirt and grime and sweat it causes some sort of shorting.
I disassemble the phone, gently with a small flat screw driver i lifted the plate up, careful not to insert too deep and applying very light force in lifting it a bit.
With a small soft tooth brush using alcohol, clean out the port at the same time I also clean the the whole mobo, at the power on point as well..
Finally using a hair dryer at lowest, to dry it up. Reassemble and manage to go to recovery do a wipe and restore, both working well.
You could just try without disassembling too, by just lifting the plate and cleaning with alcohol, but remember to be very careful otherwise you will screw up the port.
Remember if anyone wants to try this I am in no way responsible for your damage.
Hope this helps those who have similar issues, being unable to boot up and caught in bootloop may not always be software or eMMc problems. Cheers
