My i9300 all of a sudden stops charging.
I disassembled it and the next day decided to plug it in again. It charged up until 48%, when i plugged it out for use again.
Now, one day later it again won't charge... weird?
I'm trying to buy a usb port connector and want to replace it as i think the problem lies there, but how do i do this?
All the youtube video's are only replacing the simple stuff.
I have tried using another battery + batterycharger, this is not the problem. The phone still doesn't charge. I really suspect there is oxidation inside the USB connector.
Hope there's anybody who can help with replacing it.
should be the cable problem? many cases on this!
If you don't know any better about hardware, why don't you just buy an additional battery and battery charger... through could be little bit inconvenient

Thanks but this isn't the case with me. I really suspect there is oxidation inside the USB connector. So could anyone help with how to replace this? I live in the Netherlands.
You said you dissembled it, you have enough knowledge about it?
I don't have much myself too but I tried my hands on my older devices in many cases, so I can only suggest you that the charging point which is a usb port would be connected to your pcb which needs to be disconnected with the help of an soldering iron and then you can replace it with a new one. However do it only if you have subsequent knowledge.
Also before trying anything try more chargers, I came to know that none of the generic and few original ones couldn't charge mine too. Check for their voltage.

alright, thanks for the reply. But my device is flashed around 1000 times and it looks like i opened beercans with it. So this would not create a healthy warranty argument i guess. This is why i'm trying to do it myself.
Now all of a sudden it charges again, when i left it at the charger... so definately no charger problem. maybe oxidation/waterdamage from raindrops?

You have already flashed your device 1000's of time, soo i'd recommend you to flash it back to stock and try triangle away application
It did work for me
Soo .. if you manage too get system status back too normal, you can easily claim your warrenty
Put it in a bag of rice for a day so any water kind of damage is gone.

Where did you drop water? If it is within the usb port, its possible the water could have caused a short or even could have caused some corrosion. That would mean your only option would to get it fixed at some cellphone repair place. Unless your carrier replaces water damage.
yes was just going to modify it well I have no warranty so only thing is to take it to some mobile repair shop

the thing that bothers me that it still charges but after removing from charger or PC it is still charging for a few seconds after it stops you think the port is damaged? or something i can do at home as i saw the video of s2 unboxing didn't look pretty hard
There could be some dirt or slight corrosion at the port. Try gently using a soft dry toothbrush across the port. Also if you have one, try using a different USB cable.
A solution which worked for me
http://forums.androidcentral.com/samsung-galaxy-s-ii-skyrocket/179446-usb-device-not-recognized.html
This 2nd solution of pushing the tongue of the usb port up worked for me like a charm. I had no water damage and out of the blue it stopped working for me. I literally gave up when i tried this. Now everything is fine. Just give it a try :laugh::good:

I just figured this might help someone. No harm done in anyway. And yeah I still think it was worth bringing up such an old thread
Hi friends...this is the first thread by me so far and that too bcoz i cant sort out my problem by myself.
so the problem is with my neoV's screen...first it started a few times while scrolling through lists...then anytime touching any option...the display showed vertical coloured lines starting from the top coming down and went blank in 1.5 seconds...then nothing...everything on the screen gives respond on touch but i cant see anything...just blank black screen.
at first the problem went away when locking the screen and unlocking after a minute...but now...it persists even after reboots...i cant even see the boot screen...nor the recovery options...so no way to do anything.
i changed kernels via fastboot, dried the device with hair drier...only repairing with pc companion or flashing stock ftf is left...but i think the problem is not software related.
i think i have damaged my screen by charging from a samsung charger.
i will update the findings after flashing a ftf or repairing with pc companion.
any of you have any idea about the problem?
thanks.
well, I think same as you, hardware problem, LCD passed away..
PCC or .ftf and to the service center.
btw, why you mean it's caused by samsung charger?

in my case...i cant authentically say it is bcoz of the samsung charger...anyway...downloading .431 ftf...very slow conection...then if the problem persists...i will have to relock the bootloader to take it for service.
but i fear they may ask for the charger...and if i take the torn charger to them...they will straight away refuse to repair under warranty...and buying a new charger will be costly...sony equipment is always costly...and i think it would be better to repair my charger by myself and replacing the display.

Several days ago my phone started behaving strangely. Whenever the phone is NOT plugged in, the battery icon flashes continuously. If i plug it in, it stops flashing and behaves normally to show the phone is charging. Also, when the phone is NOT plugged in, the lock screen says it is charging. My battery life is dismal.
When i unplug the phone the battery indicator remains at 100% for a long time, but then drops quickly.Since this started i have to charge the phone twice a day with only moderate usage.
I am now on Shostock2 4.1.5 and Siyah 4.1.1. I tried factory reset, clearing cache and clearing dalvik. I also tried installing a different kernel (dream kernel) and a different ROM (aberration), wiping data, cache and dalvik each time.
I searched the forums, and the only threads i found seem to point to a bad usb port. One thread suggested cleaning the port, which i did using alcohol and compressed air. It helped for about half an hour, and then the problem returned.
Everything seems to point to a usb port that for some reason makes the phone think it is plugged in all the time...perhaps it is somehow shorted? So, it sounds as if my next step is to replace the usb port.
Still, I wanted to ask if anyone had any other possible solutions i could try before sending the phone for warranty repair and get the port replaced (or replace it myself).
Any ideas?
You are being kind of vague here. For instance. U say u have to charge it twice a day with .moderate usage. What if your moderate usage is 2.5 hours screen on time or something. To me, that means of course u will need to charge again if u want to make it he whole day. A bit moar info? Some cowbell?

Moderate usage means (for me anyway having the phone on, wifi on, gps off, no gaming. I only turn the screen on to check email for a couple of minutes here and there, and to answer the occasional call. Before the problem started my phone used to go all day without recharging. Now, even if i let the phone sit, unused, untouched, screen off (like overnight) battery level will drop over 10%per hour. I tried using better battery stats but none of the triggers have been triggered: if i try "since unplugged" or "since charged" or "since screen off" they all show zero seconds...I'm guessing that being "plugged in" continuously is messing with the triggers.
Still, the battery drain is not really the problem. The problem is that the phone seems to think it is plugged in continuously, even when it is not. It sounds like a bad usb port, or a port about to fail completely, but before i try to replace it i wanted to know if anyone had any other possible ideas.
People usually scrub the inside of the port with an alcohol swab if I'm not mistaken. Thought I've seen that posted, never had this problems myself.

My USB port needs to be replaced due to wear ( loose fit of cable). The ones for I777 I have found are $7.00 but are port alone, ones that are for I9100 are $15.00 but are attached to the ribbon cable. I plan to take phone apart to try to determine if the I9100 part will work. The price to have it repaired by MobileTechVideos is $40.00 plus shipping.

Definitely sounds like symptoms of a bad USB port to me. One thing you might do if you want additional confirmation, is to flash back to stock firmware (to rule out firmware issues...though I don't know of anyone who has confirmed this type of symptom being caused by bad firmware) and grab an older copy of BBS that will continue to report stats when plugged in (or maybe it will still do this if you set custom ref? I haven't tried.) There is a wakelock that will show for plugged in...vbus_present I think it is. Or you can also watch CPUSpy - if it continually thinks it's plugged in you'll get zero deep-sleep.
Thanks everyone for the suggestions.i tried sering a custom reference in bbs but no luck. No matter what i try they all show zero seconds. If i look at the battery graph in the system menu, it says the phone has been charging non-stop for the past two days, which is not the case. I will try cpuspy and report back.
Get a tooth pick and push up or down on the metal insert inside of port. May take a few tries but will work. I believe it is caused by your chargers 5 little metal cables bent when you plug into phone...

BBS update
FYI - I just grabbed the latest RC for BBS, and it now has a toggle-able option to log stats while charging (with a caveat to use at your own risk...stats may be inconsistent). Might be another tool for further investigation.

I tried cpu spy. i left the phone untouched, unplugged screen off for about 90 minutes. Cpu spy shows the phone spent almost all of that time at 200 mhz, never entered deep sleep. So it does seem to be a hardware problem, where the phone thinks it is plugged in continuously. i will carefully try the suggestion above to straighten the pins inside the port..maybe they are bent and somehow shorting. If i screw up the port....well, i probably have to change it anyway

Well it's not my cable. What it does is act like it is connected with no cable being connected. Therefor causing it to act like it is charging. Then it prevents deep sleep and wakes and vibrates every so often. Really quite annoying and killer to battery life...

My phone charges but it seems to be thinking it's always charging even when unplugged. I use it to play music at the bar I work at & it kept going in car docking mode which I never use. My battery was almost dead but it fully charged after the night was done. I went to change the battery to see if that was the problem and when I turned it off the battery charging image came up while it was off with nothing plugged in. Now my battery status keeps flashing & changes from regular size to mini size. Has anyone ever experienced this?

Searching goes a long way here my friend. This is a common problem for a lot of people. (I've never experienced it, but many others have). The solution seems to have been cleaning out the mini usb port on the phone with some 91% isopropyl rubbing alcohol and a que tip. Or if that doesn't work it may be a bad usb port.

I guess I'm in the same boat with you. Noticed a couple of days ago the phone stopped making the little chime when you connect/disconnect the charger. Yesterday I took it off the charger and after a couple hours it was down to 40% without me using it. Today, I swapped batteries and had the same problem with the battery icon. One second it shows about 3/4 full, the next it says 100%. Then I couldn't get it to boot, just kept cycling through the battery icon. Got it booted and not only does it say charging when not connected, the USB icon is in the Stat bar saying it is MTP-connected. Guess it is time for warranty.:crying:

Sky rocket yes. I wouldn't say the one x is a downgrade necessarily
At this point I might be ready to get away from Samsung. My SI had to be replaced 3 times. The S2 has had some weird issues, but worked until this started 2 days ago. I had an HTC before (WinMo) that is still working fine today. Maybe I'll have better luck with the 1X seeing how apparently Samsung can't make phones that last.
I got an S2 as a replacement. Not a Skyrocket, so it depends on when you call. Otherwise all they would offer me was the skyrocket or 2 windows phones.

What do you think would be easier, getting the part & fixing it myself or using Odin with a tricky usb port to revert back to stock?

I don't think switching out the part will be too difficult. I have the same exact problem and am planning on switching the port and ribbon sometime in the next couple weeks. I think I've read that the i9100 one works just fine.

I think the problem is actually in the logic board and not just the connector. Even if you fix it the problem will likely reoccur in time. I don't want my phone repaired, even by AT$T, just to have it fail again, but out of warranty next time. I had to have my Captivate replaced 3 times. Maybe it's time to go back to HTC. It sucks, because I love this phone.

Mine started happening after I spilt water on the end of the charging cable and didn't let it dry off completely before plugging it in. Do you still think it would be in the logic board? Then again, it seems like more and more people are getting this problem. And of course, it's just as the warranty is expiring on these phones.

Mine had nothing to do with water. I just think the micro USB connector is a poor design for something that has to be plugged and unplugged as often as a smartphone does and in the kind of environment we use them, especially in the car. The logic board is what the connector mounts to. It takes the signals from the connector and relays that information to determine whether the connection is for charging, PC connection or some other I/O function. Over time the process of disconnecting/connecting will weaken the solder joints and/or cause the thin traces in the ribbon cable to possibly short against each other and create the issues we are seeing. That's why the problems can be seen even after the cable is unplugged. Replacing just the connector will likely not solve the problem.
Talked to support. They are sending me another SII (refurbished). They wanted me to do a factory reset and download an update as part of their troubleshooting. I insisted that no software update would fix a hardware problem. *****ed enough to get them to drop it and send me another phone. My phone is rooted stock 2.3.4. Do you lose root with a reset? If I send it in rooted will that cause me trouble with the warranty dept. even though it isn't relevant to what is wrong with the phone?

Nick says they don't check. I dunno. All I know is if they can prove you messed with the phone and voided your warranty you'll get a bill for 400$
So I have had this I9100 for about a year. Flashed with CM10.1 long ago and been reflashing new nightlies when i see stuff on the github log that address bugs I want fixed. Anyway the other night I put my phone charging, I didnt flash anything that night just a normal day. Next morning phone is dead. Wont charge, wont boot, no recovery no download mode, PC wont detect anything when I connect via USB. Odd thing is that now when the battery is inside the phone it starts heating up like crazy on both sides of the back camera/sim card slot, I guess where the CPU is.
So I searched for people with dead and bricked S2 and didn't find anyone with this problem, then I searched for people with other phones and again no one with this problem.
So I was wondering if USB jig would be able to help me, or JTAG, or if its just the usb board that died since it was while charging and it gives off no signal via USB to a computer and if I changed that it would come back to life.
What do you guys think? Was it the main board or is it just a fried USB board and the phone can't regulate power without it?
Sounds like the USB board, but you never know until someone 'qualified' has a look at it. We've had a lot of similar problems on here over the past two weeks (this week in particular I've seen maybe 5-6).
Doubt a jig or JTAG would be any good given it isn't a firmware type issue by the sound of it.
I guess I'll order a usb board a replace it. If it doesnt work its not expensive anyway. About $10.
I was wondering if there have been a lot of people lately with this problem could it have been one of the nightlies that screwed up power management and fried the board?

Yep if you can get a cheap one 2nd hand it's no great loss if it doesn't work & you end up needing to replace the MB as well. If you need them, I attached the SGS2 service manuals to a post of mine a day or two ago (click on my name & have a look through my posts over the past few days) if you need/want them.
That's an interesting theory. Not being a dev, I'm not up to spec on whether anything at, say, kernel level could cause something like that to happen (In the 18 months I've been here, I've never seen a kernel/firmware pinned down as the cause of something like this), but you wouldn't say it's impossible.
Edit - Here you go, the zip is attached to this post.

Thanks I'll try ordering and replacing it to see if it lives again. Will report back in a few weeks with results.

Yep let us know how you get on, if you need to know or think of anything else, post to this thread again.

Did you try the ole toothbrush trick?? Get an old toothbrush and put it into the usb port an go mad. Sometimes a film can be on the terminals of the usb port, which gives you a bad connection.
" Odd thing is that now when the battery is inside the phone it starts heating up like crazy on both sides of the back camera/sim card slot, I guess where the CPU is. "
This doesn't sound good!
Try that toothbrush trick first before buying anything
Also did you try another galaxy 2 battery? Your battery could be dead. Have you got a multimeter handy?

Yep first thing i did was multimeter. Was at 4 volts. I'm going to try the toothbrush thing and report back.
EDIT: The toothbrush didn't solve it.

With the multimeter check is there a voltage coming from the battery. The battery by itself!. Next leave the battery out from your phone and plug in your charger (which is connected to the wall). Put the multimeter across the appropriate terminals of the phone and measure the voltage if any.
Report any voltages values you have

The battery gives off a steady 4.
The phone connected to the wall without battery gives off 1.3 when first connected or the battery removed and then very slowly starts dropping to 0 going slower as it drops. By the appropriate terminals i imagine you mean the ones that connect to the battery wherethe battery has the + and - symbols.

That USB port is working, battery is fine. Next the screen might be dead. First check to see if the backlight is working. Turn on your phone as you would normally shine a light onto the screen and see if you can see anything. Use a flashlight or something with a high focused beam

If it was the screen my phone would still vibrate at the end of bootup right?
Sent from my GT-I9300 using xda app-developers app
Bootloop is....well....a loop....a never ending cycle. ...if your phone is in bootloop it won't get far enough into the startup process to be able to vibrate. .....

Keith is right. Also not all phones vibrate on bootup, depending on rom and kernel.
Did you check to see if you can see anything on your screen using a light?

My phone did. But i tried the flash light anyway. Nothing on the screen.

That vibration normally only happens towards the end of a successful boot....so if you've felt that vibration, the chances are that you don't have a bootloop. .....the phone would *appear* to be starting normally. But if you can't see anything on the screen, your problems will lie elsewhere.....

So batery and usb charging normal. No screen problems, and heating cpu while off. Most likely main board fried? I'm gonna get some resistors to make a jig and try that anyway. Do you guys thinks 330k ohm will work too? I know its 300k ohm buthave some resistors around that add up to 330 and i wouldnt need to go buy more tomorrow.

Yeah...that CPU heating is a worry.....it's obviously being forced to do something that it wasn't intended to do....and it doesn't like it.....
And with regards to changing the impedance of the jig....probably not advisable. ....micro electronics is very sensitive to resistance and voltage. ...what you're doing with the jig is essentially bridging two connectors. ...
Impedance too low....too much current/voltage passes.....things might begin to get hot (best case)
Impedance too high.....too little current/voltage passes.....no effect.....

Ill buy some resistors tomorow then.
I wad thinking does a normal s2 perform any operation that may involve processing when putting in a batery without turning it on?
I was asking this because it could be some sort of loop in some process it does when detecting a batery.

Well, I'm sure I remember reading *somewhere* that Android phones have a secondary/simplified/low level kernel that runs even when the phone is switched off......apparently that was how some phone on verizon was hacked or something.......
Whether that's true or not....I don't know....
If it is....it could fit in with what you're suggesting....
