Hello and thanks for all help in advance. I've been using my Galaxy Note II GT-N7100 for almost four months now without any problems, but when I woke up this morning, the phone was off, would not turn on, would not charge, would not be recognized by any computer I plugged it into, and it would not boot into recovery mode. My phone would reboot randomly a while back, but that had stopped for a long time.There are not any close Samsung service centers where I live, and so that's a last resort. I tried calling local repair shops, and when I explained the problem to them, they told me that the "CPU was dead", and that "they would need to reprogram it", which would take a week. Is there any truth to this? Any ideas on what I should do?
Your phone probably had a sudden death ( unfortunately this is happening alot ) your mother board is fried and it's not cheap (around 200 $) you should contact Samsung and get a replacement
.. you were on 4.1.1 right?

How the he. ll are they going to reprogram a dead cpu? That makes 0 sense:what: And yes if you were running version 4.1.1 then it's most likely suffered sds.

Yeah, I'm pretty sure now that it's sudden death syndrome. Thanks for the help guys. The guy was probably going to take the phone, order a
replacement motherboard and install it, and charge me extra. I'll contact a service center and order a replacement motherboard.
You can try to use a soft tooth brush to clean the USB port.

Hey there, my sgn2 n7100 had the same problem before, I tried everything, even disassembled the phone apart, but it was still won't turn on or charge, won't be recognized by pc or Mac. One day when I repaired my mom's iPhone 4 touch screen, I found out that the USB port was so dusty. I thought may be it's all because the USB port was dusty then I picked up my sgn2 and used a soft tooth brush with a little pure alcohol to clean every corner of the USB port. Guess what? After 15 minutes I connected my phone with the USB wall charger, my sgn2 just started to charge again. Trust me guys, try to use a soft brush to clean the USB port before you give your phone to the repair store or somewhere else. Good luck!! Hope it helps.
I am reading about N7100 USB ports failing quite a bit. If your phone is charging extremely slowly, or intermittently, I suggest maybe investing $15 for a replacement part ($11 inc. postage) and the tools* to replace it ($4 for a mini slim-jim and screwdriver), if the alternative options are much more expensive.
* If you've already got a little phillips-head screwdriver, you can make a slim-jim / lever tool just by sharpening an old credit card.
Read on... before you just see the post and start flaming.
Been having a helluva trouble with my Galaxy Note II since a month now.
It all started a day in April when I was on a weekend break and my charger just stopped working. Not the charger, but the charger port. I even tried a few other chargers and none of them worked, whereas my charger worked on other phones.
So after the weekend without a phone I come back home and read some posts on XDA about moisture in the USB port. I blow dry the port with the hair dryer and things start working again. After a couple of days of flawless working, again the problem comes up. But it is nothing that a few 'frustrating' 20 minutes of fidgeting will not solve and so goes life.
There have been a few days where it has gotten so annoying that the phone simply wont charge no matter what I do and which angle I place the phone (yoga for phones, anyone?). The phone has even switched off completely at times. Yesterday was one of those days when it simply wouldn't charge.
So again I spend a lot of time on XDA and Google and what makes consensus is that there is moisture in the USB port, or there is something wrong (loose connection) with the USB port and it needs repair.
Few facts before we get to that, and my point about this being a software problem.
1. The charger, when it works, works flawlessly irrespective of whether it is on the table or hanging by the charger from the power outlet. I expect that in case there is a loose connection, the position becomes very delicate.
2. The charger, when it works after moving the wire around for a while, keeps disconnecting occasionally even though it has been placed on a stable table surface and no one is disturbing the table. After some seconds, it connects back automatically and begins charging.
2. The phone works without any problem whatsoever when I plug it into the Samsung car charger - never once do I remember it not working
Now here are my findings from yesterday after I almost broke the phone in frustration.
1. On a whim, I decided to do a factory reset of my device. After fidgeting with the phone for 4-5 hours and it not charging, it magically started charging after the factory reset.
2. After the reset and a 1 hour charge, I updated all the default software on the phone - including 1 samsung update, 1 allshare update, and 1 push service update. Within a few minutes of this update, the charger started showing the 'loose connection' problems again. I also noticed that at times the phone screen would switch on for no reason - for only 2-3 seconds.
3. Again I reset the phone, and force stopped some samsung services and disabled as many samsung services as I could and I could notice consistent charging.
I subsequently installed some apps (not going full out as I want to observe the behaviour) and occasionally the charging stops. I then go into the application manager and shut down some samsung services and more often than not the charging starts working.
After all this circus, I believe there is something wrong with the Samsung services, the phone device drivers, or the MTP service. It does something when it detects a cable being inserted and causes a malfunction of the phone. This is what it looks like to me.
In fact the same problem happens when I plug in the phone to the PC too. The connection keeps breaking and the phone is just not usable from the PC. However the interesting thing is that when the USB / MTP breaks, the charge is still working and the orange light is glowing.
So, finally the XDA relevant question. Can you guys help me find out if it really is a software problem or just some strange co-incidence? Are there any traces that I can pull out to see which app/service is causing the problem? There are many apps/services that I would like to disable, but they are greyed out - is there anything that I can do about them?
Mind you that my phone is not rooted - so all the usually available apps might not work for me. I use the phone as a corporate device and I can't violate rules by rooting the phone.
Any tips, suggestions, ideas, flames?
Hi I'm having the exact same symptoms as you I wondering if you got to the bottom of the problem? Many thanks

Are you sure it's not the cable? Because many stock cables tend to be crappy, just try another one if you haven't. It doesn't have to be just loose connection.
Works here fine without issues, so doubt it's software. I rooted mine almost immediately, so can't say much about that though.
Ive tried 3 different cables and every time I plug one in s voice launches lol

Could be a problem with newer Samsung phones and their construction. I have a friend who has a Galaxy S3 (not Note 2) who's gone through FOUR phones so far -- all of them with the same problem of the charging port dying after a while. T-Mobile's insurance company is starting to give him dirty looks, poor guy ...
He gets intermittent charging before the phone stops charging completely. Now his phone is hooked up to the charger constantly while he's at home because of battery issues, so it's possible he's putting excessive strain on the charging port. My thinking is that it's a hardware issue rather than software, but who knows with these things.
mudge
my friend's note 2 having quite similar problem, every time plug in the cable, the phone start charging after some minutes. not the problem of cable, i tested the cable and charger with my phone. Plan to send it to service center.

Exact same problem for N7100 (international version)
I have been facing the exact problem described above. The service center has blamed water logging to be the issue. But seriously doubt it since the port seems to be working fine when it really functions. Also i noticed that when i restart my phone few times it starts to work fine(without me touching the charger cable or the charger itself). I guess its a lot to do with the software than the hardware
note 2 Gt-n7105 bootloops, with charger doesnt boot loop
Hi,
My note 2 seems to work perfectly fine when i connect my charger. But when I disconnect the charger when its full charge it turns off.
When I turn the phone on without the charger it comes on the screen where it shows the "samsung galaxy note 2 gt-n7105" its begins to boot loop.
Can someone please give me some solutions.
Has anyone ever solve this? I have the same on my S4....
I too have the exact problem of phone getting connected and then disconnected automatically in few minutes.
I fixed mine with the same issue
Power usage
Hi,
I first saw this when I was using my sat nav app in the car, I turned off the Performance optimised when plugged in option in favour of a lower power option and the problem went away. As I get more applications on my phone I see this more and more.
Could this be the power usage of the phone? The charge will supply 500ma, if the phone is already using a good portion of that the battery will not charge, so the phone shows the charge intermittently as the phone uses slightly more and slightly less power when the cpu, etc wakes and sleeps. More apps running uses more time on the cpu so more power. And of course as the battery gets older this would display itself more.
Just an idea based on what I've seen...
My Note 5 just started doing this, and only on the car charger using the Adaptive Fast Charge port. Charges for 2 seconds, off for 2 seconds, charges for 2 seconds. Using the normal port it charges fine, just slower. I have the Adaptive Fast Charge adapter at home and in the car, it works fine at home.
usb A3 usb issues
for mine it is intermittently not being recognised in file manager and also charging and then not charging round and round making beeping noises. This started when I dropped it partially in a bowl of oxtail soup. At the time it wouldn't recognise any cable at all. After I cleaned it with a cotton wool bud it was working again for ages but every now and then it wouldn't be explorable in windows. Now its acting up again, very difficult to get it to detect in windows, it starts charging when I plug in the cable but not in file explorer.
It's a real pain because its a samsung a3 which is difficult to open. I think really I will have to get it repaired - opened up and cleaned inside properly or have the usb port replaced.
I've watched many videos about mtp drivers and cleaning and bending the usb port a bit etc etc for many of you I think cleaning the port and/or bending the usb tab a bit would help, good luck.
Stop posting your damn problems so some one can answer it. Jesus look at the posts and see if there is an answer.l cuz you asking makes no difference because u have to scroll to the bottom to see an answer any ways. So just w8. Also ya it's software thing.... Samsung kinda sucks but what the hay I love them anyway even tho thay, including the expencive ones, are crap
Hey guys I'm a newbie here so please excuse me for my mistakes (if any).
My 13 month old Galaxy Nexus i9250 started giving me problems last week when it randomly started doing 'phantom charging'. It was gone for 2-3 days then it came back again. I removed the battery cleaned up the Micro-USB port a bit and then it became normal for another 2-3 days.
A couple of days ago when I connected my phone to my laptop, Windows 8 gave an error "USB device not recognised". I tried different USB cables but without success. Yesterday the phone stopped charging from the official Samsung charger. Somehow I charged it using USB charging by connecting to my laptop. Today even the laptop charging stopped . I've tried powering off, removing the battery/sim and plugging back in countless times but to no effect.
Weird thing is, when I Power off the phone and then charge (via charger or USB) then the battery charging icon on the phone appears. The charging bars fill the large battery icon 2-3 times and then the icon vanishes. Again the battery charging icon is displayed with the same battery icon getting filled again 2-3 times. This cycle continues and even after an hour or so but the phone doesn't charge a bit.
My guess is the micro-usb port of the phone is faulty. I'll be going to get it repaired tomorrow, most likely. Sad thing is, Samsung service centers won't provide any support for the Galaxy Nexus here (I'm in India) so I;'ll probably have to shell out a lot of money.
Anyone with a probably cause/solution? Anyone with similar problem?

tried to turn on,,no response,,tried hold power on and volume up
power on and hold all keys,,nothing work at all
it even does not recharge,,and does not connect to PC
i have too much important data as well as i love this device
PLEASE HELp ME URGENTLY
Unplug the battery for a minute. If you can't get to charge after that, get a replacement battery. There was a batch of bad batteries that Samsung had issues with in the Note tablets. At one time they would replace the unit. Though, you would loose your data in the exchange.
thanks for your reply but
the battery is not replaceable in note 8.0

It is, and you can get them online. Many with battery issues have noted to pull the power ... in fact there is a thread all about this that I am surprised you missed.
i went to samsung service center and they told me u need a motherboard,,and am so frustrated
where are XDA DEVELPOERS to help me solve this issue,,,,
any trick i can try to get it back to life ??
PLEASE HELP
all service centers said the same (need a motherboard) but why the note can TOTALLY DIE without any previously notice,???
There is a YouTube video showing how to get to the battery. I did take off the back cover of my note 8 and disconnected my battery for a minute then reconnected it to solve charging and time keeping issues I had with my Note 8.

About a month ago my Sprint Note 4 stopped charging properly. I thought the battery was just getting on in age but with some troubleshooting I've noticed some symptoms-
#1- No longer shows up as Fast Charger plugged in. Whether it is Quick Charger, Regular 1A Charger, USB cable to Car Charger- it always shows up as USB Charging. This takes about 8 hours for a full charge.
#2 - Phone no longer connects to computer via USB .
#3 - Today I attempted to put a Wireless Qi Charger in, and while I was able to get some charging on a friends note. My Note seemingly is unaffected, even though the Qi Charging comes from the back plates- NOT from the USB port.
I'm guessing my 'charging unit' is damaged. Though I'm willing to hear out any suggestions.
Can anyone think of any components that would make this so?
Right now an external battery charger seems the only reasonable fix.
I've thought all these issues were caused by defective battery. You mention you thought it was battery but go on to use, "but with some troubleshooting"...
Did you replace the battery with a new one or no? If not, I don't think you've eliminated the battery.
Edit: no USB recognized. Do you have a TWRP backup?

Did try 2 other batteries. Issue not resolved.
No backups made yet- wouldn't be impossible to now since SD access is still there.
There's been a lot of root changes though, I imagine a replacement phone would be a huge bother.
What was your last full update?
Just thinking you could possibly get updated by running systemless root. But you will need to flash stock kernel as a first step.
Have you tried another ROM during troubleshooting?
Sent from my SM-N910P using Tapatalk
I haven't had a full update since roughly when I purchased the phone.
Even when off- the system doesn't recognize rapid nor wireless charging- possibly implying a hardware issue.
Safe mode also does not fix any problems.
I'm hesitant to reflash as I cannot use my USB port in the phone and could get stuck along the process on account of that.
I'm quite sure this is a hardware issue, and just wondering if/what components would need to be replaced/repaired.
There's been some exceptions around here. One guy paid Samsung for a repair, another went to Sprint and they exchanged his for a Note 4: $70.

Interesting finds- though ideally I'd get this one repaired and functioning.
My end goal is to avoid full on replacement and the hassle that comes with it.
USB Daughterboard replaced after phone got stuck in a boot loop. Phone still broken.
Complete brick. =(
Replaced with another Note 4. did NOT like note 5.
I had the same issue, when it WAS charging (which was rare) I would get about 5 minutes and it went from 100% to off and was at like 1 or 2%. Turned out the battery was defective, I had this with after trying numerous different Samsung chargers (I also have a tab 3 and S5 so I have plenty of official and non-Samsung official chargers) - all with the same results. I bought a new Anker for 15$ on Amazon and all my troubles disappeared!
