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

I have a Cingular 3125, working fine for weeks, happened that two days ago, I was charging the phone and transferring files to my computer via Bluetooth, nothing unusual, then it just got frozen, nothing responding, so I just took out the battery to manual reset the device and reinserted it, then tried to turn on the device, but it refuses to boot, no lights at all, also when I attach the phone charger, it doesnt show the usual orange led when charging, but I can feel that the phone gets warmer because the charger is attached and then after a while it gets a bit cooler, just like when it finishes charging, the usual behavior, but again, no lights at all trying to boot it or even attaching the charger, I've tried taking the battery off for hours and nothing also, and I wasnt overclocking the phone... would you say it just died? or maybe someone had same issues and solved it someway? thanks.
try this
OK, I don't remember where I read this, or the exact procedure, but give this a try.
remove the battery, press and hold the red call end key (power key) for 30-45 seconds. insert battery and do a hard reset, IE.. power on holding the 2 top soft keys while powering on the phone.
this method is supposed to clear any mother board issues and reset the phone. It has been a couple of years since I read the procedure so I am not sure if this is the correct way, if it does not work, try the same thing, only try taking the battery out, then put it back in and press and hold the power key for 30 - 45 seconds.
may or may not work, but can't hurt to try.
i had the same problem with startrek which i had bought from eBay
one more advice - try to hold record (notes) and camera buttons and insert an USB cable to your PC, it should enter to Bootloader mode
well, I have dissasembled the whole thing, I havent reached anything, even disconnected the backup battery, nothing, have checked battery with a multimeter and is full loaded... in short, someway the cell phone seems has just died, Erofich, to enter bootloader mode, the phone must turn on, it just doesnt want to start at all, no lights when connecting charger or USB cable... I'm sad because it was working fine with no problems for three months and more sad because it's the end for me to windows cellphones for a long time, I've invested a lot in this phone, accesories, unlocking, and even the same day it died also bought more memory and a neat skin cover and I'm not in mood to invest more in a cell phone so I'll use a spare crappy feature phone.
Thanks for your support.
one last effort
You could try one last thing, this has worked for me with a couple of startreks,
take the phone apart, and take the motherboard out, use a hair dryer to heat the motherboard, don't get crazy with it, but using the hair dryer on the high setting for about 30 to 45 seconds at about 3-5 inches, might revive the phone. (don't heat the battery, just the motherboard)
Put the phone back together while it is still hot (but not so hot that it will burn your fingers) and try to fire it up.
This has worker for me in 3 cases (phones that I bought off eBay that had the same symptoms as you have described)
good luck
big problem!!!!!!!!
I have been struggling to flash (again) the great pro V2 rom, but I always used my VMWare based XP windows version on my Vista laptop. Today I could use a genuine XP Laptop and I could make a connection and start the upgrade!
Sounds good? That's what I thought too, until the upgrade stopped at 70% (and I didn't touch anything), because of a connection error. I followed the text on my PC screen and I finally it started flashing again for a few seconds and then my startrek suddenly restarted, but it stops at the first splash screen! I tried to get my device back to bootloader mode (push 2 soft buttons and start), but no bootloader mode, only the 1st splash.
I solved the problem.
Hi all,
I just want to share the solution I used to solve a big shared problem I had with my X10 Mini. During a call my battery went so down I couldn't even turn it on without any sign of hope. As we know in this cases the phone CAN'T charge itself cause it need a software "help" and without a minimal charge the phone is dead. In my case scenario even with Seus holding back the button couldn't solve it.
I decided to solve it without taking it to the 60km away SE support center and:
- taken apart a usb data phone cable
- divided the red wire and the black one
- considered that the USB port gives 5v at 0.5ma
- taken apart the phone case and the rubber cap on the top of the phone
- take out the battery wires connector from the logic board
- inserted red + wire into red hole of the battery connectore and same with the black ones
- connect it to the usb port of a spare computer (you could sacrifice it if something goes wrong)
- wait for a hour to have a good charge starting point
- disconnect everything, reconnect connector, close case and connect to the normal micro usb cable
- evrything will charge as usual.
NOTE: If someone try at his personal risk, BE CAREFUL cause if something cause wrong you could ruin battery, or logic board or pc motherboard!!!
See attachment.
Bye
Nice hack!
Thanks for sharing.

Good job, but did u try to charge for a few hours without SIM card? Because I already drained completly and solved problem just removing SIM, putting to charge and waiting. After 2 or 3 hours the system start to charge normally.
WTF? This phone has this problem? Did 2.1 fix it? My wife has the habbit of letting her mobiles die.
I hope that she will not need to take out the SIM card every week to charge her phone.
Thanks for the share by the way.
Yeah this phone got this problem and it's quiet usual I see in different forums. But not always it drains so much like me. I did the BIG error to try a couple of times to turn it on. I tried any combinations of tricks with or withous sims differents ones, different buttons, different charger, etc.... No way! I think that SE support centers has got some kind of charger that has got the female connector of the battery to solve this problem.
Ah I now realised you have a mini and not a mini pro, as mini pro's can have their batteries removed.
I hope I will not have to solve this problem , any time soon.
Good to know anyway.
hello...i hope that someone can help me....when i try to turn off the device,it shut down and after few seconds reboot?why?
also simetime the phone don't turn on and on screen i see a green battery with a thermo....someon can help me?
Did you find the answer to this? i am sending my SGS2 back for replacement. i have the same errors plus the following.
Phone selects speaker rather than earpiece as default for incoming/outgoing calls
Phone on ocasions randomly starts Kies and Voice commands even if there is no physical contact with the phone
sometimes the phone defaults back to a launcher i have never seen before (it is not touchwiz) and i have no idea how to launch it without it doing it automatically.
The faults you mentioned can be bypassed with a battery pull but they are annoying, I didn't have these problems until i upgraded my firmware through Kies to KE7.
I have an O2 branded device.

Randomly my phone will:
-go into driving mode
-answer calls in speaker phone mode
-start alarm clock
-think its charging when the cable is not plugged in
-Reboot it self/turn it self on when its off

Exactly the same to me
How do you flash congnition? just over the stock rom with odin?
did you flash modem?
Absolutely same here, since coming from CM7 to VillainRom.
Never had that before.
I´m waiting and watching it and your results!
Thanks for this thread.
That's why I don't root the phone..it works fine.

This has nothing to do with root access.
I cannot believe that any problem related just because you have access to your system.
Back to topic, flashed back to cm but problem persists.
It's getting really bad near to flashing stock and bring it back to change device if someone knows what it is could be helpful.
I also have this problem. I think it has something to do with the usb port.
Because sometimes it just scans for media, or it thinks it is charging. Really weird! Then i just put in the charger and it stops for a while. Turning off will just reboot the device. And removing battery and plugging it back it also just reboots the phone.
I hope it is not hardware related...
I was looking for help for a problem I have but this seems to cover most of the problems I'm having.
Mine has recently started going into a strange mode after shutting it down. I get the battery charging symbol alternating with the "battery overheating" symbol.
The only way to stop it is to remove the battery for at least a couple of hours (if you put it straight back in it automaticly starts up and goes back to flashing the battery warnings) or pressing Power, Vol+ and Home and choosing Reboot.
I have also noticed its very slow to respond to plugging the charger in or out. It doesn't always wake-up and bleep when the charger is put in and it stays showing its charging for some time after the charger has been removed.
I was told that the charger should be removed as soon as charging is compleated but surely overnight is the only time we have available to charge these phones!
Depending on the custom rom or kernel you are using, it might not support off mode charging.
To avoid having a "problem" with charging the phone in off mode, some developers decided to make the phone boot up when the phone is been charged when the phone is off.
Going back to an official stock ROM fixes this problem.

As for Cyanogen, since built 23, you can charge the phone when it is in the "off" state. Please wipe out your userdata partition before flashing. Do not restore from a previous backup.
I fixed my reboot problem (rebooting instead of turning off) by letting the battery drain all the way so it couldn't boot anymore. Tried turning it on to see if it really doesn't go on anymore. After that I plugged in the charger and I got the charging-symbol and it did not turn on so I kept it charging overnight while turned off and in the morning it was finished and turned it on.
I also cleaned the usb-port on the phone with a toothpick. It had alot of dust stuck in it which I couldn't see. After that no more problems...for now. They haven't returned for 2 days now.

What kernel and rom are you using? I have not seen the battery overheating symbol on the sgs2.
No, there is no need to remove the phone from charger, when the phone gets to what is considered full, the battery will stop charging by itself.
Are you using the original samsung charger that came with the phone, or are you using a after market charger? Most of these USB chargers do not send a signal on the data lines. When using these chargers, the phone becomes laggy and unresponsive, there is also a delay to register anything on the touch screen. Stay away from these chargers.
For lithium batteries just charge it whenever you feel like it. Lithium batteries have a few thousand deep charge cycles, meaning if you use up all the power, then charge it,you use 1 deep charge cycle. However, if you use the micro cycles for charging, you can charge the batteries a few million times. Leaving the battery on empty for too long will damage the lithium battery.
Can any one confirm if this is a hardware or software issue as i now have the problem when i try and switch the phone off it will just reboot?
The Same issue occurs in my sgs2
hi everybody,
i just got my sgs2 ten days ago
everything seems good at first
then i realized screen standby lock lag problem, there exist a lag between 1 second to 2.5 seconds.
i ignore that due to it cannot be named as a problem, it seems like a bad characteristic
then yesterday , i have faced with another problem
after i have docked the phone to the original vehicle dock kit,
phone cannot be closed via power button , i hold it 1.5 seconds then chose turn off among list, phone looks like to be turned off then after a little while it just vibrates and reboots. That is phone cannot be turned off, it s somehow turn itself on again.
Whats the reason of this problem ?
In another forum one faced with the same problem said that it turned out to be normal when the battery is erased but the problem is occured again after docking.
micro usb connector
I droped my phone in the water, got it alive again, but with all the error(overheat battery symbol, no stable usb connection, reboot when i power off, 100% charged not going away) replaced the micro usb connector with a new one.
Some problems are gone but i still can't connect to pc (kies, debug etc), poweroff problem still happen sometime.
Conclusion: It is not only the usb part of the phone that are causing this problem.
But I do belive its a hardware problem.
Have you phone maybe got to much to drink too..
usb port???
I've recently been experiencing the same problem
When I turned off my phone it switched on again!
And removing battery and plugging it back it also just reboots the phone.
Sometimes the USB connector and charger are confused
Do solved the problem by changing the USB port?
plz help me
Thank you in advance for helping me
This is definately a hardware issue. Clean the usb connector, failing that it will need replacing

Has anyone had this problem?
After three trouble free months, my phone has developed a a very strange problem.
After charging, it behaves as if I'm constantly connecting and disconnecting the phone to a PC. It bleeps whilst showing the battery being connected to a charger and then imidiatly acts like its been disconnected by bleeping and running media scanner on both SD cards. It also shows that its connected via Kies, even though all this is happening whilst only being connected to a charger!
I've already done a full reset, which helped for a few days before it came back. It normally sorts itself out after a few minutes but the period before it "calms down" is getting longer. This morning I removed the battery for an hour but it continued in its "loop". Another, possibly related symptom is that as soon as the battery is installed, the phone boots up without being switched on. The same thing happens if I shut the phone down, it just powers up again!
Any thoughts?
had you if ever dip the bottom part of your phone? sounds like short-circuit issue or I maybe wrong.. try bringing in on to the nearest service center for warranty
Sounds a plausible theory but as far as I can tell, it hasn't got wet. Its been doing it for a few day now, so I think if it was damp, it would have dried out by now.
Thanks anyway.
I got the same problem. Let me know if you figure it out.

my friend had a simmilar issue and it was damage to the usb port , it kept thinking it was connecting to the pc or charger , it also wouldnt charge when plugged into a wall point and went into usb mode and vice versa when he put it into a pc
he sent it back for repair and they sent him a new phone
it may not be what you have but it does sound simmilar
i would try a few things like a reset , format the mass memory , install firmware again , dont restore back ups but set phone up fresh like you would do if you just bought it , then see how it goes , it could just be a corrupted file or system error that could be fixed bya full wipe and fresh install or it could be like my friends and the usb could be on the way out
on the topic of usb ports i do think they could have been better designed and iam hoping mine doesnt break as its needed for hdmi out , charging , docks , etc etc
Thanks Buxz,
As a follow up, I put the battery back in after taking it our for about 3hrs and all seams fine. I know that it isn't a permanent fix but I think it points more to software than hardware, which in a way is more annoying as its all about trial and error, as you described. A mechanical fault is more straight forward.
I just dread having to charge it again!
Regards, Woolly.
UPDATE
Charged it overnight and no problems when disconnecting it this morning. So far!
If anything, the battery life it better than before the problems. The fact that removing the battery for 3hrs broke the cycle of connect/disconnect, makes me think its soft/firmware related.
Woolly.
Dear friends,
I have solved the problem myself but I want to share the problem I faced to you, so as to contribute a bit of knowledge.
Precondition: I always use a magnetic stand to charge up my z2.
What happened: Last night I was in my grandma's house and I forget to bring my magnetic stand so I used the standard usb charging. That night, a power outage occur. Total blackout. I didn't notice because I was sleeping.
The next day when I unplug the phone, I noticed two things: the battery was at 47%, almost the same as the previous night, which is understandable given the blackout occurred. Secondly, all hardware buttons (the power button, the volume adjuster, and the camera button, as well as the magnetic pins) all fail to work. I was only able to open my phone because I enabled the double-tap-to-awake thing. The usb port also didn;t work, i cannot connect to a pc, and neither can i charge up.
Solution, I pulled out and re-inserted the micro-SIM card while awake, this automatically rebooted the phone. After that, it all worked.
Thanks for reading.
