2 days ago i had my cingular 8125 plugged into a charger . when i woke up it was off and dead, still plugged in?
now when i plug it in (to the stock charger) the red light comes on, but if i take the battery out, it stays on. if the battery is in, it is on. but i cant turn it on. ive left it for 15 hours now, and still nothing
even tried another battery.
when i first put the other battery in it turned on, was booting, but then died. probably cuz the battery was dead. but i had it plugged in as soon as i turned it on.
now the same thing happens.
any ideas?
i also thought i smelled something burnt. like if you have ever had a laptop that had a bad a/c connector and would heat up a bit, or even smoke!
dont know if it was my imagination or what?
thanks in advance

T mobile MDA shows RED LED
that is strange that you post this today, because I just received T-mobile MDA unit from 3bay that has a similar problem.
-The phone does not turn on when I press the power button.
-It does not respond to a soft reset or a hard reset.
-With the battery in, I connect the AC charger to the phone and for about 1-3 seconds the charging LED color is RED. THe LED turns off and I can not get the same result if I reconnect the AC charger.
The only visible sign of life this MDA unit has is:
-with the battery out and the AC charger connected, when the USB is removed to the point where it is not connected to the MDA, the charging LED light flashes red for a split second and the screen flashes white for a split second as well. [I hope this is a sign that there's still life in this MDA, but i'm thinking my unit is truly a brick..]
From all the websites I've searched, this does not seem to be an issue, although for me it is a scary one! Anybody that can help would be much appreciated because I want a working MDA not a dead one
EDIT: It turns out my non-booting MDA was due to a faulty vibrator and flashlight MDA part. After removing these two pieces that are connected to the back cover of the MDA housing, the MDA booted up with no problem.

I'm in exactly the same position - left phone on charge overnight two days ago and in the morning it was completely dead. I have managed to get it to power on for about 2-3 seconds on one or two occasions but now it won't do a thing
Not sure if this will help, but have you tried to push that soft reset button that you have to to push with your stylus when it is plugged in?
Sounds stupid, but my power button is completely dead and I thats how I have to start mine up. I also have to pop out the SD card to get the screen to come out of sleep mode!
I might not work, but hey...worth a try.
Well, I eventually got back up and running. Turns out the battery was completely dead. I used the 9v battery trick and then used my USB charger to get the battery fully charged and all is well.
This leads me to query how do I now charge my phone when I don't have access to a PC? I was using a standard AC wall charger and the phone showed that it was charging but due to the fact that the display stays lit whilst on external power, this eventually killed the battery as the charge indicator appeared to be false.
*as posted verbatim in another thread*
WHAT IS THIS 9 VOLT TRICK YOU SPEAK OF?!?
funny...i'm having the same problem with 2, what were perfectly fine, wizards.
which is what brought me to this forum post.
These two devices were turned off and sat in my desk for months as they were not needed. They were perfectly good, successfully unlocked and upgraded from the advice/steps/tools provided here (thanks!). They were my primary personal and work devices until i was given the option to try a few iPAQs.
Now that I want to go back NEITHER device will boot. On the original chargers (both wall and usb) both devices will display the red light as shown in the pic above, will not boot normally, or via the 2 or 3 button methods common for these devices. The batteries do not get warm, which tells me that they are not getting current...which makes NO sense if i'm using 4 different stock charging options (2 wall and 2 usb) in different locations. One expect some variable would work to eliminate some oddity, but nothing is working.
something odd is going here. how can 2 perfectly good devices and charges suddenly crapout? I could really believe it's the battery, but one is grand spankin new (only used for a month)! Both have the main board die? Both not recognizable on any computer?
Is it possible that the backup battery is causing this? Can it me charged same as the standard if its drained? I know i'm grasping at straws here, but this odd a coincidence.
FOUND FIX
okay..this was too simple.
for some reason the USB will not provide enough"juice" to pop these out of their sleep.
I have been using this great little charging system made by good old Radio Shack that is a single plug with different adapters for all different devices...i've been using it for my iPAQ's, Blackjacks, BB's, ect. SO as a last resort i went and got the CORRECT adapter (as there are many mini usb adapters available) and SHAZAM!!! they boot right up!
don't ask me why the stock wall chargers will not work, but these RS iGo systems are the trick!
i'm going to link to the other similar issue in hopes any other folks having the same issue can benefit from this.
Trying to fix a family members xt907 so here's the situation which has been nothing but headaches for me:
1. The Phone is only 7 months old and the bootloader is unlocked so warranty exchange is out of the question. She let the battery run down until the phone died. Then without charging the phone she turned it back on and it died again. From that point she couldn't get it to charge or turn back on while plugged in. At this point she brought it to me.
2. I got the phone and did a soft reset which finally got the charging screen to come up (showed the actual charging icon and the fill meter would flash up and then back down periodically). Problem is it never went past 0% after charging all night. I went ahead and tried to power it up thinking maybe it was just a glitch with the charging screen. Phone wouldnt boot. Just stuck at the Motorola logo. Another soft reset and the phone finally boots but now the battery icon showed a '?' and status showed '5% - Unknown'.
3. Performed a factory reset. No change. So I used RSD to flash the stock 4.1.2 firmware/kernel/modem, etc... What I found strange here is that despite the low battery Fastboot AP showed battery as OK, not low and let me flash (bootloader is unlocked, not sure if that affects low battery flashing or if that safeguard just wasnt built into the M).
4. So phone boots back up and shows 7% battery. Plugging in the charger at first notice has no affect. Battery stats shows '7% - Not Charging'. So I unplug the charger and the low battery warning pops up. Plug it back in and phone still doesnt register as charging, but says 'Not Charging'. Then I notice that the lockscreen shows '7% Charging'. Weird. Regardless of all that, the battery was not charging. The percentage never goes up and after reboots the percentage will remain the same. The battery does slowly discharge on the charger if I have it powered on.
5. I tried flashing a couple different roms before flashing back to stock and all had the same problem. I've formated /system hoping it was a problem with the OS but it didnt help. All of these charging tests were performed with the stock Motorola usb cable plugged into the wall charger. I tested the Motorola charger against my S4 to verify it works and also tried my Samsung charger on the Razr and it made no difference. However, booting the Razr M up with the Samsung charger resulted in the '?' in the battery icon and a notification in the status bar saying something about a CommServer starting. This notification was persistant and could not be dismissed. If I reboot the phone with the Motorola charger or no charger then that notification and the '?' dont appear.
6. I should also point out that I opened the phone up and disconnected the battery from the board and discharged the board. As a last resort I completely removed the battery and peeled back the tape on the bottom of the battery to expose the + and - terminals on the battery and wired it up to a stripped down charger and left it for a bit. Upon putting the battery back in the phone it showed a charge of 30% but still had all the same problems otherwise. So the battery is capable of taking a charge, it just wont take it through the phone, whether powered on or off. Thats what leads me to believe the battery itself is not bad. Its not practical for her to pull the battery to charge it, obviously. The phone detects the cable being plugged in and I can transfer files via usb cable to/from the computer no problem, so I'm fairly sure the Micro usb port is ok. Just refuses to charge.
A little lengthy but I'm at my wits end on this and really dont want to have her buy a $50 battery and then its a problem with the phone. I dont usually get stumped when it comes to fixing something but this one really has me. So if anybody can shed some light on this situation it would be greatly appreciated.

I presumed you tried to wipe the battery stats via the battery calibration app? not that I think it would make a difference. another option is enable/disable USB debugging. you could also try charging into a PC or a different outlet (perhaps that outlet does not provide a good current)?
not really sure, just tossing out some ideas...

I actually installed cwm recovery just to wipe battery stats. Im assuming it works the same way but I'll give the app a try. I'll try anything at this point. Tried your other ideas already though and didnt make any difference.
I appreciate the input. I'll give that app a try and see if it does something different from wiping battery stats in recovery.

Doubt it. However, the issue seems to be with the hardware, and since it is not a software issue, Motorola could honor the warranty. Last resort would be to unroot and see if you can get an exchange.

have you tried a non moto cable? the one that came with my fone was total crap, would continuously connect and disconnect when i hooked it up to my comp or try to charge it, so i tried my old samsung cable and i didnt have any disconnect problems at all. just a suggestion

Did you ever find a solution? I am having the same issues with my xt907.
What did you have it plugged in to? The fact that it said it was not charging indicates maybe you didn't have enough power coming through the charging port...

No. Verizon finally sent her a refurb replacement. I got the battery to charge up by taking it out and rigging a charger to it. But the phone still wouldnt accept a charge with the battery back in and it lost the charge it did have 2-3 times faster than normal. Battery Stats also showed the battery was showing a pretty decent voltage so unless the battery itself has a low charge circuit that gets tripped I'd be hesitant to point to the battery itself. And the charger port transfered files just fine and the phone recognized when the charger was plugged in (would go from 'discharging' to 'not charging'. So yeah, I was left stumped. Hopefully somebody else can get this solved for you.

Just an update: I ended up buying a replacement battery and it fixed the charging issue. I rsd back to stock. Then, playing around with it, I booted to bootloader and selected "Factory" and it immediately booted back to stock, but, the battery had a "?" again. Ready to throw the damn phone against the wall, I rebooted it. The "?" is mysteriously gone. What is the "Factory" setting? I think I tried it before, but had CM10.1 installed. My theory is that this "factory" boot from bootloader actually soft bricked the phone. Either that or the issue was truly the battery and simply replacing it fixed things. I am up and running now, cm10.1 is flawless, imho. Thanks for the quick reply and I hope this helps anyone with similar issues.
Beware of the "Factory" bootloader option...........
Here we go again. Upon a reboot into recovery. Recovery is twrp 2.5. What I notice is the motorola boot img takes an extremely long time (2 minutes) to turn off and cyanogenmod to begin. Could there be something corrupt in the bootloader? Is there any way to reload the bootloader on this device? Anyone have any ideas? Could it be Recovery?
Hi Everyone! I have a galaxy note 3 SM N9005 32GB. I've started facing a very weird problem recently that I cannot find described anywhere in quite the way I'm experiencing it.. My note 3 powered off by itself after running out of charge last night. Ever since then, the only thing that happens when I plug it in to charge is that the screen stays black and the phone only vibrates once. No charging LED indicator, nothing on the screen at all, just a black screen like when the phone is off. In order to get it to vibrate again, I have to do a power drain before connecting it back to a charger. There's nothing on the screen at all. Can't boot into recovery or download modes and it's not detected by a computer. Have tried multiple cables (USB 3.0 and 2) and have 2 batteries which were working fine till this happened.
Any idea of what's going on? And if I can back up any data from it like contacts and messages? Thankfully, I had transferred almost every app I could to the micro SD card (128GB Sandisk) and was able to at least recover my notes from colornote, but I digress. What is going on in my phone?
Additional info - the battery is probably still charging when I plug it in. I think this because the phone and the battery warm up after being plugged in for a little while just like they used to when the phone was working.
Even more additional info - I don't know if this is relevant, but I recently upgraded to the most recent OS version available. I think It's a 5.0 or something but I can't remember exactly. Also, the front camera stopped working some time after the upgrade. And 2 days before this, 2 apps refused to update for some reason. I don't know if this could be related.
TL;DR - Note 3 N9005 ran out of charge and is now almost dead with black screen and no LED but vibrates only once after plugging in or pushing the power button. To get it to vibrate again, a power drain needs to be done. The battery is still charging because it gets warm when plugged in.
I too had the same problem but when I connected the phone it would not even vibrate like completely dead.
Maybe try these:-
1)Connect it to the pc of it detects it then recovery would be easy.
2)Connect the charger properly.
3)remove battery for like 30 minutes and try the steps 1 and 2 again.
4) If still not working go to the dealer cause I had to go to him too. ?

I bought it off of amazon, any suggestions in such a case? Besides trying to send it back, I mean. Anything or tool I can try? I don't mind if it gets technical. Need to get my app data off the internal memory.
Though mine started with a different problem than yours, since today it seems like the problem is same like yours. Phone's display is totally black, yet I can go to download mode (cause phone is detected by Odin), I flashed the latest stock ROM of UK too, but now there is no change anyway. I want to be practical and think that this is a display problem, if not I will be more than happy. I have to send the phone to a local technician I know, lets see.
The only think I believe you can do is wait, for maybe 6-7 hours or so, with the battery detached, and then insert it back and see whether its booting with display on or not, if not its more likely a hardware issue, display possibly.
Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!

let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.
