no, wrong usb cable doesnt make the device overheating, & damaged usb cable wont charge anymore. i think the problem is ur original charger or rom what u used.
iam experience that in my old sgs+..

The Sony charger and cable are specially made for faster charging. If you connect your original charger and cable to a samsung phone, you'll see how quickly they charge up. Other cables will take more time.
Always try and use the original cable and charger. Otherwise it will charge slowly. But I don't know about the heating.
thanks
thanks everyone. i visited repair centere and they said it was problem with my charging ic.not any cable or wall socket.
i tried different chargers yesterday, he said one of my chrger's ampier rate was above 1.5A and that may cause to this error.
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.

You should get from 3.8 to 4.1.

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.

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.
Yesterday after a bit of browsing i connected my charger as battery level reached 2%. To my surprise the charging indicator din't appeared. I opened my battery monitor app to check the problem. It showed AC plugged in and not charging. The tempreature was -30C. After a little research i found out that phone does not charge under 4C. Now my phone is stuck at 1% with charger connected all the time. Since my phone is rooted i can change the value of that limit of 4C to -30C. My question is where can i find this file?
Maybe it's better to see why the temp reading is wrong? So instead of lowering the value in the system fix the temp reading, or that's what I'd do.
I really have no idea where to find the charging temp settings but I have a couple of suggestions, you could try to turn the phone off and see if it charges, or connect a magnetic charger charger, or connect both the magnetic and MicroUSB charger together while the phone is on/off.
Can't think of anything else. Good luck!

I have not done any software changes recently so its most probably a hardware problem. I have tried charging in switch off, its showing the current battery level instead of charging. Perhaps the sensors work even when the phone is off. Tried magnetic charger also, results are same as microusb charger. Changing those value is my last option.

Really??
I didn't know that! I've charged my phone with magnetic charger for some time,(a month, more or less) and it just died.
But it didn't die after using it, it died the moment I connected the magnetic charger.
Hello XDA friends,
I have two captivate phones I want re-purpose to use as wifi security cameras using IP Webcam I have them fully setup and working with the app, but they seem to overheat and shut down after an hour or so. I also have two Galaxy 2 Skyrocket phones that I have done the same thing with them. They had the same problem with overheating, but I found this post which led me to remove the battery and solder power cord directly to the battery terminals of the phone. My understanding is that the constant recharging of the battery and the power needed to run the phone is causing the overheating, so by removing the battery and eliminating the charging to the battery equals less heat. That has worked for about two months , still working. I tried this with the captivate phones but for a reason I don't know the phones won't boot up without the battery even with power directly to the battery terminals of the phone. I have removed the back of the phone but I am unable to see where I might connect directly to power the phone without the battery. I'm hoping there are are some users on XDA that might have the technical knowledge to help me either with the overheating or the direct power connection. I appreciate any help. Thank you.
Sean
************************UPDATE PROBLEM SOLVED*****************
In case someone else wants to try this I am posting my resolution here.
Although there were no replies to my plea for help, at the time of this update I see that 52 users at least viewed this thread. Thank you for looking.
I have been playing around with setting up these phones as network cameras on and off for awhile now. After posting this thread, I continued to research the issue, then I found this post by ADAMOUTLER, discussing the middle battery pin (battery size indicator). This led me to test the resistance on the battery between GND and the BSI. The measurement was 1500 ohms. I connected a 1500 ohm resistor to the BSI and the GND terminals of the phone, then cut the end off of a usb cable, connected the red wire to the BATT+, the black wire to the GND- (battery connection pins on the phone). I plugged the USB cable into a charger, pressed the phones power button and
Voilà! The phone turns on and boots up no battery installed. I now have it running the IP Webcam app, streaming video through my home network, I can view the video on my other smartphones (OnePlus One), and on my home network computers and from my computers at work. It has been running for several hours now, hopefully the overheating issue has been defeated. I believe it has.
Thank you ADAMOUTLER for all the amazing work you have done and shared on this phone.
So, first, i'm sorry for posting in the wrong place, but in the help section ppl seems to be inactive
So, yesterday my note started to blinking in some parts of the screen, like a flickering or an interference and stopped to charge correctly. I only can charge it to 74% and it discharge very very fast, and i know that it seems to be a battery problem, but it could be a usb port problem? Cause, i've tested a lot of USB cables and in some positions them was charging, and in ohter, don't, and if i use it while charging, the phone discharge. Sorry for my bad english!
I'm facing same problem, and I have to leave my GN1 untouched until it charges completely.. I'm using USB B cable that looks to attach better to usb port. As GN1 is not my principal phone, I'm OK with this battery. I installed night owl nougat and it seems to be better charging GN1.
