so i had a not so nice scare last night. :crying:
TLDR:
when i attach magnetic charger, i now get blinking orange light and i get the charging (lightning) icon in top status bar also blinking also showing up and then disappearing.
I can apparently charge my phone via micro usb port directly but this morning phone alarm didn't go off and i couldn't get the phone to wake without powering off via red button and powering on again.
- How bad is this? (i.e. is it corrupt software? is hardware borked?)
- What can i do to determine cause (is there any kind of log file i can look at? etc)
I've been using a knock off magnetic charger adapter (one end is micro usb female, other end is magnetic charger port for Z2) since end august. pretty much every night i use this thing to charge my phone.
here is the item on ebay
Last night, as i was about to sleep, i connected my knock off magnetic charger thingy to my phone. i think i may have connected it upside down but then i fixed it.
I then left it for a bit then came back to check something on my phone and could not get the thing to wake up.
i tried to use the power button to wake phone to no avail.
I remove the magnetic charger clip thing and tried to power off phone using red button next to sim tray. no dice.
I tried plugging power into the micro usb directly and got a red light. At this point i start freaking out.
I start hunting through XDA and all signs point to potential soft brick.
So I try putting my phone into flashmode. I tried a bunch of things as recommended and somehow got my phone to wake again, but it got stuck in a boot loop at sony logo.
I use the red button to power off the device, wait for a bit and then power it back on.
luckily it boots into ROM and my phone looks as it should. I attempt magnetic charger but I get blinking orange led and the charging (lightning) icon in top status bar also blinking. I decide to try pluging the microusb directly into port on phone and it appears to be charging.
I decide to go to sleep.
In the morning my phone alarm didn't go off and i couldn't get the phone to wake without powering off via red button and powering on again.
All day today the phone was fine, but going to sleep now i'm going to charge direct via microusb and wondering what its going to be like in the morn.
- How bad is this? (i.e. is it corrupt software? is hardware borked?)
- What can i do to determine cause (is there any kind of log file i can look at? etc)
- any other recommendations?
thanks in advance
If the device powers off due to the charger then stop using it because it will damage your device and void your warrenty

@envious: yea thats the thing. I'm not using the magnetic charger anymore.
i'm plugging into micro usb port.
this morning it was still normal at 8:15 (could wake it, unlock all things good, battery fully charged).
I have an alarm that goes off at 8:25.
I went back to sleep.
alarm did not go off. I woke up at 9 and my fone could not be woken. it was not off because if i hit power button it would vibrate, but i had to hard power off with red button and turn on again for it to be normal.
anybody seen this behaviour before?
well jsut a quick follow up. i uninstalled my alarm app and reinstalled it and now i no longer have any issue when charging via usb port.
still don't know if magnetic charger is completely eff-ed tho.

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 plugged in my razr before I went to bed. I've been using a HTC plug and cable for the last few months no problems. Woke up this morning and battery was at 5% and then the phone died completely soon after. I plugged it in using my original motorola plug and cable. The dual core screen came up and then the battery level said 0% and it looked like it was charging. It died again after about half an hour. Now nothing will get the phone going. I also tried the hard reset (Power and volume down). The phone is unrooted and hadn't been updated to Jellybean yet.
Any ideas what I can try?

Try using the correct charger and charge it for about an hour, thats the first thing I would try. How long is the htc cable you're using because the longer the cable the slower the charge.
I have tried multiple different chargers with no joy. I think the problem is with the connection. When I plug a charger in the white charging light flashes briefly for a second. I checked the connection for dust and it looks clear?
Try Booting into bp tool or hw diag (hold vol up and vol down then press power should see black screen with white text vol down moves cursor vol IP selects) the phone should charge if left in one of these modes (if you can even make it this far without the bat dying that is). if that don't work could try disassembling then charging the battery directly (never tried this its only an idea try at you own risk)
My xt910 razr maxx has suffered exactly the same fate overnight. Worked fine yesterday now it's dead with the only sign of life from the white led when attaching the moto usb charger. Phone wasn't run flat prior to this. Baffling

Yes I have and no button combination produces as much as a glimmer. I've had the back off and checked the battery for charge, it shows 4.3 volts so it's not that. Something has failed catastrophically I fear.
Check the battery's cable that connects to your phone.If that cable was broke,you can just see the battery level but without charging it.

I've read around this a little now and have invested £3 in a Motorola Factory Cable of fleabay which hopefully will resolve the issue. Due to be delivered next week so I'll keep you posted......
Well got the factory cable and tried it holding the vol down button. Nothing. Took the back off the phone and checked the voltage of the battery 2.75v. Removed the battery and tried the factory cable with vol down. Still nothing. Reinstalled battery and left charging off a pc overnight, this morning it had risen to 2.83v. Starting to think that this phone has had it
Cut the end off a micro usb cable, exposed the wires and connected the red and black to the battery terminals then plugged it into the moto wall wart. Left it until fully charged....volt meter read 5.1v, the output of the charger. Disconnected and checked charge, 4.2v out of the battery.
still dead. Nothing. No red moto screen, no recovery nothing. Something else must be amiss. All I get is a brief white led flash when I plug in the standard charger cable.
anyone have any ideas where to go from here other than the skip?!
Just resurrecting this thread in the hope someone has found a solution....
I still have a brick which is unresponsive to two factory cables plugged into my PC with and without the battery in.
Trouble is I've got pictures on there I'd like to recover if possible which causes me to persist with this troublesome device!

I access the boot menu by holding both vol up and down, and pressing the power button (hold for ~2 seconds, and release the power button, while still holding vol +/-. Volume down will only send you to APFastboot. Check out the post, I encountered the same problem. The final method I tried was the winner. Good luck, and let me know if you have any questions.
Thanks for that, I'll certainly give it ago when I get a free hour one evening this week. I am concerned though that the factory cable doesn't work, I was under the impression that the phone should at least respond to its connection in some way - it doesn't even when vol-is depressed when connecting to pc.
The only response I get from the phone is a brief flash of the white led as the usb cable (factory or charging) is connected to it.
That indicates that there isn't any power management remaining on the phone, and the battery is pretty weak. You'll need to get the battery charged up manually. After you flash with the last method I used, you should be able to reconnect the battery and charge the phone all the way up before booting. Sounds like you're having the exact same problem I did.

Really , Really wanted this to work but it doesn't look promising.
Made the USB charge cable as described (white and black twisted together to -ve, red on its own to +ve). Battery removed from phone, usb on charge cable connected to PC.
5 Volts found at the battery connection terminals. Original Moto Data cable connected to phone then PC. White LED flashed on for slightly longer than before then off. No response from phone - nothing on the screen or vibration with or without any combination of Vol- and vol+.
Battery refitted and charge lead attached to terminals as above to charge from PC. Now reading 4V across the terminals charge lead plugged in, 3.84V cable unplugged so presumed charged.
Still no response other than the brief white LED from the phone with either the Data or Factory cables and Vol-(or any other Vol configurations).
Any ideas???
I assume you tried pressing and holding all the buttons, for five or ten seconds, or even a little longer, to try a full reboot. Beyond that, I wish I could help more. I'm slap out of ideas. This was the last step for me (as the solution usually is). The main board might have had it, though I don't have a clue why.

I'm thinking dead mobo too. When it died it did so overnight without provocation - no flashing or tinkering, it was left on the kitchen sideboard and found dead in the morning. oh well I've tried. many thanks for your help:good:
Glad to try and help. I guess it's time to move on to the next device! Let us know if the phone sporadically decides to work, or you figure out a solution!

I am not sure if you already watched this video, its for droid razr maxx, charging a dead battery and works perfectly for droid razr too.
My droid razr was exactly in same condition, white light and no charging, did not power up, completely dead.
I popped open the back case, connected the modified usb cable wires to the positive (Red wire) and negative (black wire) ends of the battery and let it charge (stay connected) for one hour. Then i pressed vol up+ vol down + power button. And my phone switched on.
If only your battery is dead, this should work.
So I've just acquired a Commtiva N700. It's been sitting in a desk drawer for several years, and the battery is completely flat.
When I plug it in to charge, the red power light comes on, but it remains completely unresponsive. It doesn't even show up as a USB device if I plug it into a computer. After a while the power light will start flashing irregularly. Even after being left like this for a while, nothing happens.
I've followed the suggestion on one of the other threads of taking the back off, disconnecting the battery, leaving it for a bit, reconnecting and charging. I just get a flashing red light again.
I'm suspecting that the battery is so flat that the charger circuitry is refusing to charge it because it thinks it's broken, thus rendering it a brick.
Before I bin it (not worth replacing the battery on a thing like this!) does anyone know if there's any last-ditch recovery I can try?
Hello,
Im having problem with charging My xperia z2
Recently I tried using magnetic charger for first time but it wasn't charging at all and phone started getting more heat so I removed it and got back to USB normal charging but now its not working as usual... when I connect usb charger phone showing charging symbol and red light on but its not charging at all, turned off phone and tried charging while phone off still same ..getting red light on and charging bar in the middle of screen and phone stuck on same percentage and goes down slowly even it keeps screen on charging bar after I unplug the charger !?!
I tried hard reset using power button and vol+ afew times some of the tries worked and phone charged normally but after i plug the usb charger again problem gets back ... so i keep resetting phone many times till i get lucky and charge normally
Also tried factory reset and flashing new stock ... still same
I don't know but i have feel that magnetic port causing problems for battery even i didn't use magnetic charger again
and i read somewhere it might be possible to disable magnetic port?
any idea?
help would be appreciated
any help?
When you connected the magnetic charger first time, have you connected it in the correct way? If it is connected upside down, it ll cause serious issues..
LikeTh3DON said, you probably connected your magnetic charger in the wrong side. I've done the same with my D6503, and I have the same issue. I already looked to change the battery, nothing change, it's a chip on the motherboard I think.
Look on that thread, some users have the same issue, no solution so far:
http://forum.xda-developers.com/showthread.php?t=2745786&page=3
If you can, use sony's usb cable and charger, or a usb port on your laptop, don't know if it's related, but my phone charge easier with those. If it's the same issue than mine, your phone will charge to 85-90% and the screen will constantly goes on. When it happen unplug your phone or it will heat a lot without charging.
Same thing accidently done with me.now phone dsnt charging with megnatic cable(charging on and off regularly) nd with USB its have same problem when battery % reaches above 90.
Please give me solution..
Is that repair is available for this issue?

Hey,
I haven't necessarily got a solution for your problem but thought I can offer you my opinion. I've used solely the magnetic charger for nearly a year as my USB port has clean snapped off from my logic board. The whole time I've not had an issue, the only time the device heats is during intensive games or/whilst charging.
I know that people have had issues with the magnetic charging port in the past, it's a relatively easy fix, however, will involve opening the device and stripping out a lot of the parts to get to the ribbon.... up to you what you want to do.
Guess I should ask the obvious, have you tried different cabled/ chargers etc?? the fault could potentially lie with the cables if they've been damaged/frayed.
Hello,
My phone's battery was starting to have issues so I bought a new one and replaced it yesterday. I've done it recently on another phone (same model) so knew what I was doing when reassembling it, with the right adhesives and everything. Then I left it plugged for the night as this was advised by the new battery's seller. But this is what happens this morning when I try to turn it on:
- Phone doesn't vibrate when pressing the power button, neither when holding different combinations of Power + volume, etc.
- When I plug it this is what happens: imgur[dot]com/fByubwN The screen turns on as it would normally do, displays the 100% charged battery logo and then just dies (with the green led remaining). The only way to turn the screen on is to unplug and plug it again. But the phone itself isn't booting.
Any thoughts appreciated!

I'd say that the battery is at fault. It can be two things:
- it is not correctly plugged (maybe the connector is not perfectly aligned, or one of the pins is bended)
- it is completely depleted, so won't charge at all.
Disconnect phone from charger and try to test voltage on the motherboard with a voltmeter. If you can't read anything, disconnect the battery and test it directly.
Personally I would say the first problem is more likely - a completely bricked battery is not that common.
Actually the battery was fine. I've opened it again and turns out I've kind of messed up with the flex connectors of the motherboard.
So I was able to boot it while it's open but as soon as I reassemble it, the controls are not detected anymore. It's a matter of millimeters, some parts probably don't sit properly, etc.
We spent some time on it with a guy at a local repair shop, the conclusion was that I had to get a new phone, or a new motherboard which is almost the same haha.
Thank you for taking the time to reply!
