I had this phone for about 10 months. it was purchased from India. It was working fine the night before, I woke up and found it was off, and isnt responding to the charger, is not responding with USB cable, not turning on by Power button. I have tried all soft reset & hard reset methods available on forums.
The phone screen remain black and cold when connected to charger same situation with USB cable also.
Can any senior/ developer help me to come out of this problem as I am in US right now and not finding any solution to turn on my phone.
Try another battery (probably won't work). Try a jig (ditto). Return to service center given it didn't die as a result of a bad flash (JTAG repair may not work).

Too bad that last thursday I used the charger from a kit similar to this (link found in the forum 3 months ago).
(h**p://w*w.befr.ebay.be/itm/Dock-Sync-Cradle-USB-Charger-For-Samsung-I9100-Galaxy-S2-II-Plug-/260876977248?pt=PDA_Accessories&hash=item3cbd7ac460), directly (without the cradle)
It was the first time I use the power adapter directly to recharge my phone.
And since thursday my phone detects unexpectedly usb connection (and says I ave to close all aplications to use with Kies etc...).
I suppose it is no coincidence and that this fu***** charger damaged a capacitor or another electronic component of this kind inside my phone!?
What do you think ?
What can I do? Send it using warranty? Disable USB detection (how?)?
Thanks a lot in advance for your help!
Edit: Now the phone is not recognized when I connect it to computer (usb) or it starts the car mode!!!
A lot of people have this. Try brushing the usb connector on the bottom of your phone using a CLEAN and DRY toothbrush.
I had this problem, this fixed it for me ever since. Also bending the connector a TINY bit to the middle of the hole may help. But watch out, as it's horribly thin.
Two connectors are bent because of your new charger, or dust is causing the problem.
Thanks for this first answer! But...
Three others things (I've cleaned the connector as you said to):
The screen lights up by itself, too! And 9 times out of 5 when I press the power button (in order to lock and switch off screen) the phone just freeze and the only way to get it back again is to remove/replace battery!
By the way the battery drains faster than usual!
Do you still think it's only a matter of dust/connector (just asking but strange coincidence...)!?
Hello I have exactly the same problem since 2 days first it started thinking its connected to the USB, second thing is it wakes up soon after you have put it down and if you press the power button it freezes I have tried it more than 50 times and it freezes every time (when its connected to the charger only froze once) and today when i try to connect it to the USB nothing happens.I have tried Hard Reset , restore to a stable setup with CWM but it wont help. This happened when I got home after I was 2 hours outside working and it was very cold and moist but I only had the phone outside my pocket for 1 - 2 minutes to make a call and some very tiny drops got on the screen.I regret taking it with me if I only knew that was going to happen. One other thing I had an App to track the battery state and now when the phone thinks its connected yo USB but its not the program says my battery is over voltaged. What happened with your phone . Can someone help
Last night i went to bed after reading on my sgs2 i9100 international version running cm9 stable
i woke and found that the phone was off. Trying to turn it on by pressing power didnt work
no response when charging it via wall charger
wont go into download mode or recovery
my dearest fellow sgs2 owners
i need your help
what to do?
it might be some hardware fault.... get back your samsung store to check out device ASAP
if you are using a cover for ur S2 , just remove it , and press the power button directly for 10 to 20 seconds ( keep holding it )
ive contacted samsung and because its still in warranty theyll either fix it or replace it with a brand new one
but id still prefer to fix it myself. so far nothing has worked.
is there any way to trouble shoot the device and find out what the error is.
fried mother board etc?
Hello,
I have Galaxy S2 and having some charging issue. Yesterday, when I plugged it in the wall charger, it didn't get charged (i.e. even the flash on battery was not coming up) and when I tried to restart the phone, it powered off but didn't switch on. I tried holding the power button to turn it on but it didn't. So, I pulled out the battery and left the cell for some time like 20 mins or so. After re-inserting the battery, it turned on but still was not getting charged. I tried to change the USB cable as well but nothing helped. I then tried to charge it via my Laptop it actually started the charging process but with error on Laptop saying "USB Device not recognized".
Today, I tried the wall charger again and here's I found something: when my phone is ON and I plug it in the wall charger it doesn't charge but as soon as I turn the phone OFF, my phone starts getting charged (Battery image comes on screen which usually comes when the phone is off). So, that's how I am charging my phone.
I went to the repair shop today, he said it's a charging port issue on which I have some doubts that why it is even charging in this way if it's a port issue. I just want to make sure if whatever he's saying can be somewhat true.
Can you please help me out? I would be really thankful to you.
I look forward to hearing from you soon!
Thank you!
PS: I tried to search about the port issues but I couldn't find anyone having this kind of issue so please!
The issues you have mentioned really do all point to a faulty USB board......it is common (with a faulty board) for some functionality to work while other functionality is lost. The part itself costs pocket change and is reasonably easy to DIY replace......
If you want to go down that path, check my profile for threads I've started.....you'll find a guide explaining exactly how to do it.
Just make sure to read and note the section on 'rev versions' it is VERY important to get the correct one......
My wife says I'm a phone geek....She's probably right
hello everyone,i have updated GT-I9205 to 4.4.2 (sprint) stock, the first week was pretty good, at the second week my phone suddenly shut down and wont turn back on the battery was about 35-40%, i tried to connect to wall charger but no sign of life also tried from computer the same again under device menager no device was being added, after a day of trying i was nervous and just keept pressing the power button for about 5 minutes and than it turned on and no problems till yesterday, as usual i have putted the phone to charge when i gone to sleep and when i woke up it was 33% and not charging, when i put the charger it says usb connector connected and wont charge, ive tried to go to download mode and maybe flash with an other stock firmware but wont be recognized, i also tried to wipe data/factory reset but no luck, so i thought it was a hardware failure while trying i've found out that when i am in download mode with usb cable connected and take out the battery the phone stays turned on, than realized that if i connect the usb cable while the phone is of and than go to recovery mode then reboot, when it boots it charges the battery but keeps no notification that its charging just the regular battery icon and if i take out the cable and put it back it says usb connector connected but wont charge , does anyone know what to do with this, is this a hardware issue (i know that if i change the motherboard it will be okay because of firmware) or is this a software issue(what im thinking it is), does anyone how can i change the firmware without odin and without being rooted, or is anyway to root 4.4.2 without odin than install an other firmware or what should i do (instead of killing myself hahahahah).
Sorry for my bad English and if i was not clear please let me know than i will record a video and post it here!
Thanks for your time.
Kind regards from Prishtina DB

thanks everyone who was here, it was a hardware problem I've fixed the connector on the phone now its working fine, so it has not being a software problem.
Hello, I have a Galaxy Note II sgh-t889. The phone worked perfect until I recently flashed it to Android 6 with cynogen mod. The phone worked fine for a few weeks, now the phone only powers on when connected to a charger. When removed from charged it goes back to the Samsung note II logo screen and won't boot past. I don't think it's a battery issue as I can boot in bios and it shows the battery is %95 full. It will sit on the logo screen until charger is plugged in, then will boot fine to OS. I've factory reset multiple times to no avail. I've read other forums of users who experienced similar issues and have narrowed it down to a possibly corrupt flash. The problem being, when connected to my pc the phone won't boot to home screen, it just sits on the logo screen. (So Odin does not detect the phone) The solution I was told is to flash it back to stock/oem rom. The problem is I can't get it to bboot to home screen when connected to pc, only on wall charger. If someone could please give me some insight, I would be more than grateful. I don't have the money atm to buy a new phone, so my only option is to try and get this fixed. Also I don't have an external sd. Can someone point me in the right direction of what to do ? I'm so stumped and I can't stand having to pack my phone around on the charger all the time...
