So i recently picked up an XT1254 for a great deal. The phone is pristine, not a scratch on it. It looks brand new. It is totally unresponsive. If I plug it in the light on my charger turns from blue to green, telling me it's fast charging. But nothing from the phones LED. Also if I place it on a charging pad, color changes as well. I tried both options over night and still nothing. The phone does get warm (usual amount), leading me to believe it is charging the battery.
Holding the power button - nothing (no vibration, no moto logo, no LED responce)
Holding power + vol down - nothing ( = )
USB to PC - phone is not detected at all (I have ADB and current moto drivers installed)
I opened it up, and everything seems to be in order. No loose connections, no water damage. I checked the battery, and it reads roughly 2.5 volts across each pair of pins. Should it be reading 3.7-4 volts across each pair?
I unfortunately don't have another phone to check the MB, battery and LCD against.
I don't have a SIM installed in it, but I doubt it makes a difference?
Any ideas or advice would be greatly appreciated! Thanks-

Quite low for li-ion/-poly, I don't think it ever sees 3v or under in normal circumstances. It might be well into "damaging the battery" territory at this point, and it should certainly be higher after charging it for a while...might be a goner.
Have you tried removing the battery completely and running it off the USB cord? I would expect it to, if nothing else, bring the screen up complaining of a bad/missing battery. That said, I've never tried unplugging mine to see what happens, so no real idea.
I would suggest trying to fabricate a factory cable (which would provide power directly, ignoring battery status), but I don't know if post-OMAP Motorolas are physically configured to use them. If they aren't, it'll do nothing at best and burn up traces at worst : \
Also, holding Vol - while plugging it in should bring the boot menu up, regardless of available battery charge (therefore serving as a quick test to see if the power button is the problem). But that might go out the window as well if the battery is deader than a doornail.

It doesn't. When I fresh-install a ROM, I remove my SIM card to make sure none of my data gets used before I can turn various unwanted syncs/auto-updates off. The phone doesn't care at all, and nowadays Google isn't too whiny about a missing SIM either.
Hello guys.
Sorry for reviving an old thread, but I have similar problem with my Droid Turbo. During the replacement of the battery and speaker, I noticed oxidized resistors near the proximity sensor (which wasn't working since the purchase of the phone second-hand). I have cleaned the oxidized residue with ethanol and assembled the phone. After pressing the power button, the touch buttons light up and phone was vibrating every 20s but the screen was blank. So I disassembled it again to check all the connections but everything was fine. Since then, the phone won't even vibrate, just heats up a lot after holding power button. I have tried both batteries, speakers and also powering the phone without battery (only power cord connected). Both batteries are shoving around 3.8V.
Do you please have any suggestions how to fix the phone? Or should I assume that the motherboard died?
Thanks

So I've fully discharged my phone following the instruction given by a battery calibration app. But now the phone won't even turn on and I can't even recharge it. I tried to pull the battery out and put it back in, and then plug in the cable and turn on the phone, but hell no, the phone gave only 8 short blinks and 3 long blinks from the amber colored led and went dead.
I don't know if this is related to MDJ's unity V5 beta kernel, but my phone is unwilling to recharge while it's off. Can somebody help please?
Btw, I can't even boot into bootloader by holding vol down after pressing power button.
Charge your battery min.3.6v on external charger or another phone and then put it back.
lol found a solution, a badass one too:

Ghetto Solution:
I have a spare, semi-busted USB cable.
I stripped off the insulation and exposed the green, white, black and red cables.
You only need the black (-ve) and red (+ve) cables for this effort.
Use any means you have to get expose the actual wiring and be sure to match them properly to the corresponding contact points on the battery.
The idea is to directly place the positive wire on the positive terminal of the battery and vice versa for the negative. The plug the battery into the phone.
What I did was loop the wires around the leads that would be in direct contact with +ve and -ve inside the phone itself, plugged the battery back in the phone and then plugged the USB cable into my laptop.
The phone booted right up.
Seems to be working thus far even though its still "off". I have a solid amber light and I'll leave the phone for a little bit before I try to boot it back up.
I hope this helps.
DISCLAIMER: I take NO responsibility for any damage (physical, psychological or emotional) you or your phone may incur should you attempt this.
It worked for me.
YMMV.
Be advised and tread carefully.

and if we're not feeling so badass?
I don't wanna go messing with my USB cable, but I'm in the same boat as the OP. When I plug in to wall or computer, there are 9 dim orange short flashes on the notification light, about 1 per sec, and then two longer flashes, and brighter too, then nothing. Any other suggestions that are maybe a little less bad-ass and a lot more usable?
Any help would be GREATLY appreciated!
I got my tf300 some time ago, and just today i recieved all the components needed in order to change it;note that the tablet was disasembled for more than a month, but before that, the battery was charged, so it remained like a month like that as well i don't have best memory of the disasembly proceedure.
So today, i managed to pack it back (without putting the back cover of the tablet, and tried to boot it, but nothing happened.So i put it on the charger where a sound (charging sound) beeped and a red led turned on (later green).I let the tablet charging for more than half an hour, and tried to boot it again but no sign of life at all.I removed all the screws etc and disassembled it for one more time in order to check if everything was put right.
Both digitizer cables was secured.
Screen cable was fine.
Also i tried to check the on and volume rockers cable and by mistake i ruined the plastic top of the female adaptor, but the cable still fits fine inside (that happened during the second disassebly so it was not the original cause for sure).
Also, i noticed that there is an on/off switch next to the power button.This switch was ON the whole time.
I found a button at the digitizer circuit and pressed it (tablet off).
I've tried to remove the digitizer and try to boot.Nothing happened.
What i am afraid of, is that the whole proceedure make me burn some circuit of the tablet by static electricity or by sort-circuit something by my slightly swetty hands.

Uhh, the on/off button should be always on ON if you are turning on the tablet, always have it like that...
Also, make sure that the digitizer's end is well plugged

"...I found a button at the digitizer circuit and pressed it (tablet off)...". How do you mean? If you're referring to the reset button on the Touchscreen pcb, that usually does not turn anything off, just resets to boot the tab again. In any case, you said "tablet off", meaning it was "on" before that? How do you tell it was on then? One way to find out would be to hook it up to a tv via HDMI. If it comes on, either the lcd or the cable is the problem. I've run into a situation where the tab works (comm. thru PC) but the graphics part is dead, hence no display, in which case the only solution would be a new motherboard as graphics reside within the CPU.
I mean it was turned off before i press the button.I will try to find a cable in order to check it on TV, but if hte GPU is dead how the HDMI works?By the way,i just tried to plug the tablet to my PC, and the PC recognize the device!That probably means that the device is on,but something goes wrong with the display.

If the GPU is dead then of course there won't be any display. But how do you find out? With the HDMI connection.
Its been more than a week since my Moto G died. Before it happened it had 40% battery. The was the first 2 days the phone turned on quite a few times, only to make it to the boot logo. After that it didn't do anything at all and I lost hope. But 3 days ago it started doing something weird. Every time I connect the phone the LED lights up and turns off when disconnected. If I leave the device charging the LED stays on for like half an hour. Then it comes back on, in like an hour or so.
I've tried a lot of ways to turn the device but nothing helps.
Does anyone know what does the LED mean?

I'm not an expert on the subject but, I think the LED lights because the battery, try to restoring the stock rom via fastboot, if you don't know how do this, just put in the google: Motorola Moto G XT10XX Stock ROM
XX is the model, 32 is the Single SIM version, 34 Single is the SIM Model AWS (I think that is Moto G bought at T-Mobile and AT&T), 28 is BoostMobile version and 33 is Dual SIM version
Sorry for my bad english

The device don't boot and you can't go to fastboot mode, now I think that is a hardware problem, the better you can do is send the device to assistance
The Cells may be dead or very low charge. Um remindea me of my old blackberry, try holding power then plugging charger in, keep the power button pressed though

following is motorola forum text
My device does not seem to be charging, or is doing so slower than I expect. What could cause this?
It is best to use the Motorola charger that came with your phone. Chargers have different output capacities, and a weak charger will take longer to charge your battery. If you are using the device heavily at the time, it may be possible for a weak charger to fail to provide enough energy to actually charge at all.
Inspect the charger. Ensure it is not damaged - check the insulation on the wire for cuts, ensure the micro-USB plug fits securely into the device, and that the transformer (the larger portion with the wall outlet plugs) is not visible damaged. Some wall outlets can be loose - the prongs of the plug do not firmly make contact with the conductors inside the wall. While connected to your phone, jiggle the charger at the wall outlet and watch the battery icon at the top of the phone's status bar. If the charging icon Image shows intermittently, try using a different outlet (and get an electrician to replace the loose outlet).
If your battery is completely discharged, it may take several minutes for the device to begin charging. The battery needs to charge to a minimum voltage before the system can boot up, and this may take a few moments to achieve.
If you have already been using your phone for a while, sometimes a collection of applications are using resources and background services that keep your phone more active than it needs to be. A quick and easy test is to reboot your phone if you have not turned it off in a long time (> 1 week). Press and hold the power key to select the Power Off option. Then turn your phone back on and charge your phone normally. Try to observe if any particular applications that you use correlate with the phone using dramatically more energy than you expect (discharging faster or charging slower).
Your phone is a complex device. If you believe that something is wrong with it or how it is behaving, please contact MotoCare and we may be able to provide more detailed assistance.

The weird thing is it died at 40% and when plugged it in and tried to turn it on the first few times I saw the battery screen state a 40% charge. Then when trying to turn it on It showed the boot logo and then screen went black. After those few times (3-4) the phone didn't even power on or show the battery screen. I'm screwed since the bootloader is unlocked. So I can't return it. Its been more than a week and I really miss the phone and android and now I'm stuck now with my iPod touch. Guess I'll have to start saving to buy a new phone.
Weird thing is my previous phone died in a similar way: I was in the car and it suddenly turned off and then it did nothing.
I was removing the inner plastic of the phone and accidentally shocked the board in this area. After that I can't charge my phone or see any display although I see Google pop up a few times with the digitizer flickering. Now without that battery I can hit power and it would vibrate. But other than that I can't see anything.
Here some pictures. Is my phone dead? I tried changing the USB charging ribbon L piece but that didn't work out. Wasnt OEM and poor fitment.
Cant post the image
Here it is

Without the battery I can power and it would vibrate without nothing on display. With battery it does nothing. Although I saw a red light briefly. I can NFC charge it. But won't power still. Not sure if I should spend any more money on this used banged up $80 n5.

Which part of the phone is or board is it linked to. Also I did anther experiment without the battery back light comes on see grey if I tap the online I see pixelated rainbow or TV black n white lines. Weird..
The area that you are pointing to has the battery connector right beside it. It could be the battery or the board.

Question even without the battery wouldn't the phone turn on and work as normal without the battery?
I've never been able to get an N5 to boot without the battery being connected, even an almost dead battery would allow the phone to boot as long as it is connected to a charger.
Well oh well thought I had a chance to fix it when the backlight and the phone would power on with 99% no display. Battery seems to charge through NFC but what's odd is that with the battery I can hold power nothing happens. Without battery it vibrates and I think it boots up but I'm not completely sure. I'm guessing because I would go into recovery and I can feel it vibrate once going into bootloader second time I hit the power button then it vibrates again. I think first option is to start

Don't worry, it can be fixed. I just fixed mine yesterday after spending 2 days contemplating buying a Nexus 5x due to this one being broken. For a few days my mic wasn't working then I realised that pressing hard just below the camera hump got it working again as you can see in the link below I replied with my solution, I suspect the problem isn't the long connector on the left but maybe a loose component behind it on the other side of the mainboard. I jammed some folded paper behind the board and now it works fine. Jamming it in front of the board worked but from time to time the screen went off and I had to reset the phone for it to work again.

Hi,
I got a Z3 which was described as having no power and just flashing red LED when power button is pressed, after being dropped flat on the floor in a gel case.
The phone is in good condition with no external cracks or breaks and the only damage is the USB connector flap doesn’t stay closed.
I decided to take a chance on it thinking maybe the battery connector had come loose or similar.
When the volume up button and power button is pressed it vibrates 3 times.
When the off switch is held it also vibrates - but not every time.
When charger is connected the red LED sometimes comes on for 5 seconds then goes out.
When trying an a stiff apple type micro-usb lead, a couple of times I got a solid red LED. I left it on charging for 24 hours but the LED remained red and it was still the same - no power.
So I suspected maybe the micro USB connector may have damage.
Not detected by windows or Xperia/PC companion.
Sony Mobile Flasher just says “Device disconnected”.
So I decided to open it up.
It had previously been opened up and possibly the battery changed as is had horrible double sided sticky stuff holding the battery in and the back cover to the battery - cheap shop fix to avoid getting the proper adhesive seal?
The battery connector seems loose and I couldn’t be sure if it was connected properly.
The battery voltage was about 2.70v so I was thinking maybe below what would be correctly detected.
I decided to boost charge the battery for a bit.
At 3.30v I put the battery back in but the behaviour was the same - maybe the LED flashed red a few times at various points.
Any advice what else to try?
You help much appreciated.
Thanks.
try removing the battery plug in the phone to your pc and start pressing the power button rapidly if it gives a green or a blue light then your is phone is ok it might just be a battery problem but if not
You are in a heap of trouble
In most Cases the red light only cames on when there is somthing wrong inside the phone
it can be easy as a battery replacement
Or worse like mine it can be an Power Management IC that is shorting out due to lose or bad connections
Hope this helps
