My 'charger' I'm using is nothing more than cutting the end off of a usb cable, stripping the red and black wires bare, and twisting them so the strands are tightly twisted. Then I carefully stick the red into the positive pin slot of the battery and the black into the negative. I then insert the battery into the phone and snap the cover on. Plugging the usb into a charger makes the phone think it's fully charged so I can flash.
I just wanted to put this here in case anyone has a low battery and needs to flash. If anyone needs more info/help let me know.
There is a special cable you can get with special wiring, often referred to as a Motorola factory cable, that can power the phone through the regular charging port instead of using it to charge, and that can also be used for basically the same purpose as what you did. There are multiple places online to buy these. It is another option for those who don't want to modify cables themselves.
I should get one of those as we've still got this Bionic and a MotoX in the house.
I was considering posting some warning about that cable, but found this page I'd previously read with various precautions and warnings and other info, I think written by the person who released the schematic for the cable: http://www.shop.teamblackhat.info/Factory-style-programming-cable-for-Motorola-FactCable.htm
There may be more phones it works with than those listed, but personally I'd only use it with ones people somewhere have reported that it works with.

I was surprised to see that, upon trying to charge the Nook Color for the first time, that the microUSB connector is very brittle to say the least. I was having a hard time even getting the nook end of the cable to be fully connected, because I was afraid I might break something. It eventually would go in with a violent SNAP sound, but it was still scary.
The next time I needed to transfer some files/charge, I tried one of my generic monoprice microUSB cables and didn't have the same issues. The connection was made with no fuss, and everything works the same. This may seem like an obvious thing to do, but, in case there's someone out there that hasn't tried a different cable and had the same concerns as me, it's a better route.
A regular microUSB cable doesn't have the power connectors on both sides (or something to that effect). I read a B&N support post over on their forums and someone mentioned trying another microUSB cable. Support warned they would only get a trickle charge without the actual Nook USB charger.
Had the same problem, almost like fishing around with the stock nook cable to get it to seat. My motorola works a little better, but still seems like a quality issue with the alignment of the micro USB on the bottom of my nook.
I think the nook wall to USB charger is 2 amp which is more then the standard 1 amp chargers that most phones and devices come with.
Does the stock cable have additional connections to light up the status light at the tip? A slow charge is better than possible snapping something off the Nook itself in my opinion.
No, the secondary power lines on the connector aren't just to light the status light though I'm sure that's part of the power draw. It'll just take you twice as long to charge. If you're an overnight charger, that might be alright for you.
I see. I also just checked the the ac adapter. It puts out 1.9A--way more than a standard USB charger. Maybe that has somethng to do with the special cable as well.

I also had some quality issue with the default cable. Changed the cable and it was fixed.
Mine was bought around Christmas, have they fixed that issue with the latest versions?
Don't think so, because I bought mine earlier this week. However, the USB connection with the factory cable seems to have been magically fixed. I have to be really careful, but the B&N cable fits better now. Strange.

Hi guys,
I wanted to use my NexusS in the car. I have a 3rd party cigarette lighter to USB which I put a mini to micro adapter on.
The phone does two strange things...
Firstly the screen will not go off - it won't time out and if I switch it off it switches itself right back on again.
Secondly, even though it says it is charging the battery life depleted - and fast too. I watched it loose 10% of its charge in around 10 minutes.
Any ideas - is it just a rubbish USB adapter (worked fine with my other phones, most were HTC).
Anyone else seen this - and fixed it?
/R
try a different charger. If issue stops, you've got your answer
Try a name brand (not cheap or generic) cigarette lighter plug that has a USB female on the other end. You could use the supplied usb data cable that came with the phone for charging (that's just about all it's good for). It's a straight cable so it won't be pulling on the phone when it's charging and if you're using it (if the cable is long enough) I hate coiled cables with a passion! Yeah it might be six feet long if you stretch it out but it will always be pulling the phone if you use it while charging.
Some cables aren't wired inside like a standard usb cable is. Lg is notorious for that. Some of their older phones refused to charge if you tried to use a standard usb cable. For a good data cable, that isn't cheap quality, I suggest the sprint usb data cable that the corporate stores sell. It's built good and has a solid connection. A less expensive one is an ultra brand usb to micro usb cable that you can find at compusa. The six foot one is perfect. Yes you can find others online cheaper of course, but as a local solution, you should be able to find these stores. I don't know the quality of any that might be sold at best buy or your cell phone company. Generally from what i've seen, the cell phone stores that have lots of generic accessories, have dummy phones or all their phones in a glass display case are the places that will probably have low quality cables. Some people don't care about stuff like that and some run into problems with flashing or being detected correctly by the computer or the plugs wiggling in the sockets and possibly causing intermittent connections. See where I'm going with this? Imagine you are flashing and halfway through it or at a critical point of data transfer. The plug connections aren't good or solid because they wiggle. The contacts momentarily lose connection and the data stops... Stuff like this is a bricked phone waiting to happen imo. Both Samsung and HTC cables that were supplied with the phones with my past phones seemed like they weren't very good data cables. Some may have never had a problem with these but I have. Times when phones refused to flash or be detected by the host computer, then the problem went away when I used "better" quality cables.
Sorry for my usual rambling when I reply. I like to explain things in a way that a non tech person could begin to understand.
As for your original question, I have experienced this too. Almost always a reboot fixes that problem. A good tool to use for charge and discharge info is a widget called battery monitor widget. I turn the sampling rate faster to like five seconds and the battery capacity to what the battery is actually rated at. The widget always seems to guess the wrong capacity of the battery. You can watch and learn what your phone normally idles at and when something is really sucking a lot of power. On the flip side, it will show you when the battery is trickle or charging it hard. Mine idles at less than ten milliamps and I've seen it charge as much as upper nine hundred milliamps (970's+).
sorry, gotta stop blabbing!
Stuck in fastboot with low battery?
You dont NEED a new battery or a charger, i know many people use their phones for more than just games and dont have time to order one or go to the verizon store, so i went out on a limb and tried this. I figured, if i can jump a car, i can jump a damn cell phone battery
You'll need:
USB Cable (to cut)
Wall or car charger with USB port
Cut the USB cable
Take RED and BLACK wires (you wont use the other ones)
On your battery you should see a + and -, insert the RED wire into the + on the battery and the BLACK into the -
wait about 20 min, and try fastboot again
This fix is confirmed on Droid 3, but should work for all batteries, even 3 prong ones. (confirmed by youtube)
I would have put this in development but i cant post there because im a newb and dont know anything

this definitely works. I have done the same exact thing on my old droid x. You actually dont need to wait. If you place a piece of scotch tape taping your wires onto your batt, then cut a slit in tape above each wire, carefully wedge it in your phone, obviously leaving it plugged in, then go about your business, it works just fine. For the faint of heart, but if your impatient like me works like a charm.
yeah! i couldnt find anything about this problem thats helpful, so i figured, well, not much harm i could do, so i just winged it! and it worked. i think not many has tried it because of all the alarmist posts about li-ion batteries being dangerous.
but now i cant get past step 17 of flashing, it fails at cdrom flashing:/
(obviously completely unrelated to battery)
Hey all,
Before I even start here, please no snide replies about using the search box on here or anywhere... if the answer is out there, I'm at a loss for the keywords to get it. Fair enough? As FYI, bootloader is (was??) unlocked, rooted, and has cwm recovery.
So I dropped my MB886 cracking the screen (round of applause please) and in the process of disassembling the case to install replacement I tore (severed) the battery connection cable. Fast forward to phone now reassembled with new screen and battery installed --> -->
The phone now has a green LED that will respond with blinks to button certain presses i.e. the simulated battery pull, but the device doesn't show up in lsusb output or device manager. I've read of similar problems where the phone has been brought back, and I've read of the exact problem with no solution. Basically the only two things I've really read that supposedly work are battery pull button sequence and using OEM charger/cable to get battery to take a charge.
Unlike, say the Atrix 2 where the lonely white LED is there to serve as a reminder that it is a hard brick and that's all you're ever going to get from it again, I haven't even read that this is in fact the #1 sign device is now a brick. So could someone verify it is or isn't? I've never tried to access a device this way, but Is JTAG an option?
I don't get why this should be, despite battery issue, it's all simple hardware swapping involved here as the software wasn't touched and was 100% working even with cracked screen.
Thanks for anyone with an answer or the direction to one.
2 things it could be then: you over- or under-tightened the new battery cable screws to where there isn't a good connection with the board. The screws have to provide equal pressure on the positive or negative contacts or otherwise there's a fault in the circuit.
OR
Your new LCD/digitizer is defective OR wasn't seated well.
Since it was working before, and since you didn't break anything else (to your knowledge), those are the two things I would check.

hey, thanks for the input. I remember battery connections being snugged when I originally took it apart, and to be honest, short of having a mini torque wrench I don't know I could put them back any closer to that. the digitizer could certainly be either defective or perhaps have a bad connection, and i am certainly willing to test/check for either, however do you know that this would prevent the phone from booting or cause it to only display the green led as a sign of life? something of the "halt on all errors" in pc bios? seems logical that the led would (or could've) been used like the oc speaker and blink out some code relaying you've got a bad O2 sensor or the gas cap isn't tight.
Over tightening can cause problems. So loosen them a bit if it's just-short-of torque wrench tight. I don't know why it does, but I've read people had problems when they over tightened those screws. That green light could be telling you that the battery is connected poorly.
Is there a possibility that the battery is so depleted that it won't charge? For that, you need a factory cable to charge the battery with power off.
Sorry, to clarify, no I just snugged the battery connections when reassembling, I only meant that i don't think i could get them any closer to the way they were originally without aid of something like a torque wrench.
As for battery charge as a potential issue... to be fair, I only have a OEM Moto wall charger and I think the cable I am using is Samsung. Surely the cable itself isn't the weak link in this chain? A car battery on a multimeter reading 12.0 volts is something like 50% charged and about 12.8 volts is looking pretty good, anyone know what I should get out of the 3.8V Li-Ion on a meter?
PS I double checked the both data cable connections to the motherboard, so I doubt just a bad connection is to blame here.

When I say "factory" cable, I'm not talking about the cable that came with the phone. There is a special Motorola cable (that you can even make yourself) that can charge your phone in situations when your phone is normally not willing to accept a charge.
If all else fails, try this: http://forum.xda-developers.com/showthread.php?t=1077414
Yes! This is brilliant and certainly answers a few questions. It'll take me a bit to get this together to try it, but I'll post back when I get a result. Cheers!

Scratch my previous answer. Seems I misunderstood what a "factory cable" is for. It can't actually charge your battery, instead it is used to power the phone so that you can flash/diagnose it, even when your battery is dead. Normally, you need a working phone to charge the battery (with the stock "charging cable").
This information may or may not help you. At the very least, using a "factory cable" may allow you to power your phone on, which would tell you whether the problem is your battery or the phone.

well, i'll take it regardless... i've acquired one of these mythical factory cables and it gets me into fastboot and recovery, so i'd wager, even though i haven't seen it, that it would boot all the way. so being that i don't have either the original charger (although have one that's motorola) or cable (samsung), my best bet is probably just find a store that has both an OEM motorola charger and cable even if they're not for the MB886? surely one for a moto x would work to charge battery, no?
or is this like a chicken and egg problem i now have? a catch 22? i can't charge the battery without a working phone, and i can't have a working phone without a charged battery? golly gee, anybody out there with an MB886 want to charge my battery for me? can i just hotwire the battery to a couple of leads from a charger and bypass using the phone as the charging device? at least to give the battery say 15%-20% to get something to happen... like get this rain cloud perpetually parked above me to blow over from above my head for a day or two maybe?
so, with phone plugged in with "factory cable" here's what i get and when... the phone bootloops on the "bootloader unlocked" warning screen if i don't press anything. volume down gets me fastboot, volume up gets me recovery. phone shows up in both and takes commands... so is it possible i just need to restore a nandroid backup, or is the battery charge the better bet now? i would just try the nandroid for $h!ts and giggles, but the last one i have isn't as fresh as i'd like, but is certainly usable if i must.

Any generic USB charging cable SHOULD be good enough to charge and flash your phone, especially a Motorola cable. I'm currently using an old Blackberry cable for everything. They should be all the same. In rare instances, a cheap cable may give you issues (I think I had a cable from an old Samsung phone that I couldn't get to work right).
I guess just keep trying until you find one that works. Hate to tell you to go spend $20+ on an official Motorola charger...
Regarding your battery, yes you may be in a bit of a pickle. I've never had to do it, but I've read of users who had to short some leads in order to directly charge the battery. Trying searching through the forums, I'm sure the info is here.

All hope is lost, I am now looking for a replacement.
Ok, so here's where I am at with this now... As we're basically talking about any regulated power supply that can put out an excess of (around) 3.8V and 800mA I've opted to use an old ATX computer power supply and wired the mini B USB end of a cable known to have in fact to have charged this very phone... nothing. I have also, for sake of hope, even tried using the wall wort from an iPad (which puts out a cool 5.1V and up to 2.1A). The green LED will shut off after a while of being plugged into said charger, but still no booty action.
As stated before, the phone still works with the factory cable.
So, I gather from this that...
A. some hardware component (i.e. resistor, etc...) on my phones board that is involved in the charging process has gone kaput.
or
B. There is some software flag flipped somewhere that could be unflipped with or without some trickery to what actually is VS what I want the phone to think it's seeing.
Anyone have any thoughts on this or something similar pertaining to B as a course of action?
*update to my update* ... umm, which should now be up to date??
I did a complete wipe of the phone (/system, /data, /data/media, /cache, and /dalvik-cache) and reinstalled the rom... and still nothing.
I got this used moto g6 xt1925-12 and it's having an issue where it's not charging in any normal mode
It does charge in fastboot mode but only up to 70%
There are no charger or cable issues as I already verified it and works with another phone
I am thinking there some chip or control device that is not recognizing the usb when I plug it in in normal mode so I was wondering if I could bypass whatever is controlling it and connect it directly to the battery
If I had a schematic I would try to see what is controlling it and perhaps replace it if that is even available on the market but without that I have to use brute force
So I was wondering if there are any electronics experts or perhaps someone who knows how a usb c is generally implemented in a phone or more specifically in the moto g6
Would connecting the usb c directly to the battery cause any problems ?
Even though you verified that your charger and cable both work with another phone, I would still try different combinations of cables and chargers. Various things can happen to both cables and chargers that render them less effective (a cable can have one internal wire fail, a charger can have a resistor fail, etc. etc.). Also, some devices are more persnickety about the power they receive than others. My GoPro Hero 5 Black was able to charge its battery and interface with my computer through a USB type C cord that didn't work with my Moto G6 at all.
That said, I can't offer much help additionally. Given the cost of a Moto G6, I doubt it's worth hours of soldering to get your battery working normally again. You might want to look into a replacement battery from eBay, but even then, you might still have issues because as you said, there could be a fault with one of the chips that manages charging. Allowing the battery to fully discharge once or twice might be worth trying.
Sorry, wish I could be of more help.

Thanks for the reply and trying to help
The phone I verified with is the exact same model xt 1925-12 so I am sure the charging system outside of the phone is fine I also bought a new battery and just plugged it in to see if that makes any difference which it did not and just last week I replaced the charge port and while that looked a little dirty and was missing one pin on the end which upon looking at a pinout found out to be a ground pin of which there is more than one so of course that did not make any difference
I understand it's a cheap phone I just like to get to the bottom of the problem if I can and perhaps do a little troubleshooting inside the phone
There has to some chip inside that controls everything since it's charging in fastboot mode but not in any other mode
I just have to try it and see what happens

I think I found something that may be a little safer than a direct jumper
I came across a video on Youtube where the guy installed a diode The video was about fake charging so that's not exactly my problem and it was on an older phone with micro USB and not USB C but in theory this may work
There was also another video on changing the ic charge ic on an Iphone 6 which was a BGA I am not even sure where the charge ic is located on the Moto G6 but if it's a BGA I don't want to mess with it unless I have to plus it's probably not even available to buy anywhere so I think I will go with the diode method first and see if that does anything
