Ok let me start my sad story. Months ago i upgraded to ICS and all was fine untill the phone started giving me that error " charging paused voltage to high". I used my nandroid to go back to GB and it was the same. Since then i changed Ics versions, now im on Cm9. I used contact cleaner spray and it actually worked for a few days. Then i got the problem again. In the last month there was no more "voltage to high" error but the phone was not charging anymore, usb or ac, unless i reboot the device. Then it says its charging but it doesnt say USB or AC, just charging. And today it stopped charging period. No matter if i reboot or not. The thing is that i bet you will all say its the USB port, and i might agree but if the micro usb port is broken tell me why odin recognize the device instantly in download mode and flashing goes smooth or why when i use my USB OTG cable my flash drive connects flawlessly and the copy operation runs perfectly? I dont get it, thats why i need help because i love my Sgs2. If there are other threads i appologize but im a seaman and im sailing alot hence my online time is either very limited or expensive.
Thanks in anticipation!

Obviously a problem with the charging circuitry. You can replace the board yourself apparently (not something I'd try), you can send it in for warranty repair or a local non-Samsung authorised repair shop should be able to repair it fairly quickly I would have thought. We see this problem on here all the time.
You could always try another battery and/or charger if you still think it isn't this problem. If you do have the same issue with a new battery/charger, then it's definitely the problem.
You've done everything you possibly can to rule a hardware issue in/out (you've gone back to stock, back to GB, cleaned the contacts), there isn't a great deal more you can do other than the above.
Hello forum! Recently my phone died due to unknown circumstances. I thought it might have been water damage so I disassembled the phone and swabbed the PCB with isopropol alcohol and left the phone in dry rice next to a heater for 24 hours. This didn't fix anything so I took it back to the store of purchase and asked to test a new battery. Success, the phone turned on with a new battery in, however, when it was put on charge, the phone became abnormally hot. I thought this may be due the new battery, but it wasn't. After a small period on charge the phone paused charging because the battery temperature was to hot, I removed it from the charger it had only accumulated 30% charge and 20 minutes later the battery level had dropped to 2%.
Someone has suggested I was sold an aftermarket battery, however at the time the person from the store claimed they had to get a battery from a new S2 box.
So, I'm a bit lost as what to do next, could flash stock firmware and take it to a samsung service center, but I'm more interested in a possible DIY fix and the knowledge that comes with it.
...
Okay, yeah a return would probably be the best way to go about it. When I opened up the phone and had a look inside, the moisture indicators looked like a small white square with purple crosses on it. I would post a link, but new users with less than 10 posts cant post links.
But otherwise I think I'll follow your advice, and return to stock/un-root, I don't want to risk toasting the phone even further.
Thanks.

Have encountered more issues. Was in the process backing up phone. Turned off phone so I could reboot it into recovery and do a full wipe. But it refused to turn on, and doesn't show any signs of charging again.
So can't really return it to samsung or its place of purchase because it's still rooted.
What are the chances it the power IC that is malfunctioning?
I'm considering buying a charging/usb port from parts4repair, I've heard that the xda community has had good experiences with that website.
Any advice for a person in my situation? Bite the bullet and buy a second hand SII?
I have an AT&T HOX+ and basically it's dead, but I figured it was worthwhile asking for suggestions. My phone was rooted and running ViperXL, working normally. Then I dropped it, while it was plugged in. What I managed to do was mangle the micro USB port beyond usability, while the phone had 1% battery. At the time it seemed like the phone was otherwise totally fine, so I figured this wouldn't be an unreasonable fix.
I brought my phone into a local repair shop with good reviews and had them look at my phone. They said the USB port was a simple fix, 20$ part and they did fix it. Four days later I get a call from them saying we're really sorry, but we did the fix and the phone still doesn't work - it seems to be a problem with the logic board. I picked up the phone yesterday and basically confirmed what they said. The USB port is fixed but doesn't appear to serve much purpose.
Here are the symptoms: nothing visibly wrong with the phone or charging port, other than the fact that it won't boot. When plugged in, a small red LED blinks every ~1.5 seconds in the speaker grille. When the power button is held down, after about 5 seconds the three LEDs light up for 2 seconds then turn off. Nothing else happens.
Edit: I should add that the blinking LED continues when not plugged in. Plugging the phone in doesn't really appear to do anything.
The repair people are probably right and it's the logic board - which is pretty unhelpful. When I asked what they suggested, they said any repair is going to be very expensive and it might be worth getting a new phone. I've only had this phone for 4 months so I have another 20 months of happy contractual obligations. At this point I'm looking for any suggestions on where to get this phone repaired. I may have voided whatever warranty HTC offers by getting my phone repaired aftermarket but when I researched the warrenty, it didn't seem like it would cover this issue anyway. I haven't tried bringing the phone into an AT&T store yet. Thank you!
I don't know that I can give you a definitive answer, but I can say that the blinking red LED is (or can be) caused by the battery having no charge. If you ask me, I say that even though the USB port is fixed, it's not delivering any charge to the battery.
That seems pretty likely which means either the repair people didn't correctly put on the new part or by dropping it I broke something more complicated.
I guess my real question is more about repair / replacing the phone. Is there an official repair outlet for HTC that could repair it? At this point paying is inevitable but I'd rather not buy a new phone if possible, although the new nexus GS4 is tempting.
The blinking red light means the phone doesn't have enough power to even power up. I don't know about the other 3 led thing you talk about, but try to leave your phone charging for a couple of hours and then try to power it up.

It doesn't seem to be getting any charge at all when plugged in, so replacing the usb port must not have fixed the problem.
better to buy a brand new HTC unit
I suggest you charge it continuously for an hour and then try to switch it on. Same thing happened to my phone and this is what I did which worked!

Hey guys, it's been awhile since I asked a question, but here I am, lol.
In a nutshell, I'm pretty sure something in my device (hardware) is fried, but I thought I'd see if anyone knows better.
The problem is my device seems to be sending power out of the usb port, and doesn't connect to the pc or recognize it is charging correctly.
This also applies to download mode (windows says device has malfunctioned) and when powered off (there is no battery that shows up when plugged in). In order to power back on after turning it off, I have to remove the battery, then reinsert it while holding down the power. I can't think of much that could have caused this, other than I was visiting places with high humidity levels. One unusual thing that happened before this started was my device rebooted into safe mode when playing bad piggies. That was really weird since I have tried booting into safe mode before, but thought samsung must have disabled it for some reason. I have already tried wiping data and flashing a new kernel/rom. Obviously I can't re-partition since I can't connect to my computer in download mode. What do you guys think? I think it is time for a new device.
EDIT: I should mention that it started behaving normally yesterday for about 5 minutes, but then it went back to this.

I'm 99.9% sure that under normal conditions that an Android device should never power the USB port. Source of speculation. If it is indeed powering the USB, then you've either got a really wonky firmware installed, or some sort of hardware issue. I'd try to make sure that it's sending power out before going further (especially if you can't charge it, the battery will be dead soon). After this test, I'd keep the battery out for a while, just to be sure it's not going to short anything.
One thing I've noticed in my tinkering is that taking a device apart, then putting it back together again can mysteriously fix problems (although 75% of the time the fix is temporary). If you suspect water damage, opening it up and letting it air out might help. I want to say there are certain cleaners that are great for cleaning up any water spots that might be shorting things out, but I've never had to try myself.
That's all I can think of right off. Good luck.

Yeah, I'm working on taking it apart right now. With my limited experience on electronics, I would be willing to bet it's a capacitor that's gone bad somewhere. That wouldn't be a problem on a desktop since I could just solder a new one in, but I don't think I have the skill to do something in such a small scale, not to mention I don't think you can even buy them that small.
The same thing happened to me, and I had to send it in for repair. Luckily, I was still in warranty. Also, are you sure it's not the charger cord?

I've tried multiple cables, and I'm unfortunately out of warranty.
Upon disassembling and cleaning with rubbing alcohol, it seemed to be working properly, with the exception of computer connection. However, I plugged it into a DC car charger (leaving the charger itself unplugged from an outlet), and the light came on again (which is what I was talking about when I said it was sending power out), and now it is acting weird again. I guess I'll take it apart and clean it again...

honestly, i cannot begin to fathom what could be causing this. it seems to me samsing paid more attention to the charging port then say amazon did on the first gen kindle.
i do however, wish you the best of luck and hope you somehow manage to fix it

See! Told you taking it apart and putting it back together again works... temporarily. :silly:
You're right, that does sound like power going out. Which would be super cool for powering, say, a micro USB laser pointer, but it's not so great when it should be charging. Can you double check with another device that the charger doesn't light up normally? I know my wife's laptop charger has a LED that stays on for a long time after it's been unplugged from the wall, sipping off of power left in the charger. It could be something similar with your charger.
Just a though... if power is only suppose to go into the device, then wouldn't it be reasonable to assume to that there would be a diode forcing power to only go one way? Or does it need to cycle power back to the charger? IDK, but it might be worth looking to see if something looks missing.
I read somewhere that if the battery voltage gets too low i.e. battery is totally flat, a current will flow from the device to the charger so this may be what's going on here. I didn't really understand the post as I was just whizzing through the thread, but i think the solution was to charge the device for many hours until the battery voltage was high enough for normal charging to occur. I'll try and locate the post, but it might take a while

@iJimaniac if all of these suggestions dont work, there is the possibility to just buy another battery and a battery charger and keep switching out the batteries when they die
Maybe @henk5066 would know something about this?
From what it sounds like, your power circuit is fried and is not directing power correctly this means that you're probably going to have to replace the mainboard. however don't worry. you can get one from a player with a broken screen on ebay for about 10 $. I can p.m. you some links to products on eBay with main board working and not screen and I can post a video on YouTube that shows you how to replace the board. it's actually rather quite easy. I don't get why most people don't do that and instead buy a new one. let me know if that helps

Wow, I didn't realize a broken player is so cheap. I'll look into it, and instructions won't be needed; I've already fully dissasembled my device many times in the past, just for kicks.
Edit: could you send me those links? I'm having a hard time finding very many under $25, which is still a good price I suppose.
the broken player it's self is cheap (0.99$ if your lowest bidder and win) it is shipping that makes up for most of the cost. Just make sure you get one that says powers on, that is the main indicator that the main board is still good.
EDIT: I just looked on ebay, aparantly the person i bought my new board is out of the 4.0 player. and it looks like there is however one with a 9.99$ bid. you could raise it and get the player but that is the cheapest you will get. i will pm you a link to it.
I had the same problem
I had the same problem, what i did was, instead of charging it with the original charger, i charged it with my nexus 10 charger in download mode all through the night, and the next day it would have about 80 percent charge and it was in the system, but it drained quick when i would unplugged it, so i repeat the same procedure over several days until get to 100% and scince then i have had no problems with my SGP, hopefully i helped you

Interesting, i thought the devices could not charge in download mode.
On the subject of odd charging behavieor, has anyone noticed that when plugged in running cyanogenmod overclocked to 1200mhz, the micro usb port area on the player gets rather hot?

So a few days ago, when I got up in the morning for work. I noticed my phone was off, even though I leave it on the charger turned on.. Turned it on, and got a message , the phone was powered off because it detected it was overheating.. Weird? While coming home from work, I had it plugged into my car charger and it seemed fine.. Was up to 69% once it was unplugged, it went down to 49% in 10 minutes.. Put the phone back on the charger in the house, and after a couple of minutes it powered off again.. That same evening went to use a different charger from the wifes Samsung work phone.. The phone would not charge, but would charge hers.. I tried a different charge block and her power cord.. it would show for the phone to reach 100% from 61% 3+ hrs. A couple of seconds later it was not charging.
Ok, tried a different charging cord, and my wife's charging block.. Time to reach 100% 14 hr 57 min..So today I took it to a Samsung repair center not far from my home.. They told me, the phone would not connect to their computer so they could diagnose it.. it was charging fine, so the told me the main board was bad.. They are ording one and will install it next Tue. I never had a issue with my other Samsung phones overheating, or needed to have the main board replaced..
I will say this.. Best Buy is suppose to be a Certified Samsung repair center.. But what I found out, they only service their Flagship phones.. I asked Samsung directly. when I called them first about the overheating issue, before bringing it into them.. Best Buy does not have all the tools to fix all their phones. But they do have all the tools to fix all their flagship phones???????? I find that odd for sure.
I purchase this phone, because it suits my needs.. I have always have flagship phones, but they are not needed for me at this time.. I'm was so pissed about this issue, and first getting alot of running around from different sources about this issue. I was almost ready to trash the Samsung and android all together and go Iphone..
Best Buy is a certified Samsung repair center. It is posted on their website. They just seem to do their high end phones. They also are listed as which devices they fix. Which is Samsung latest flagship phones S9+ and up.
I brought my phone to a actual Samsung repair center. The new board for my phone will be in next Tuesday.
When I started to read this I was constantly thinking this is a battery issue because its charging is so erratic. Now I wouldn't normally question the repair centre but I'm not certain how the main board would cause this. You mention charging a lot but not if the device can be powered on or used. If it can then theres no way there is a main board issue. Virtually all Samsungs have a secondary board which handles power and since your issues seemed power related, I would have thought that would have been culprit number 1. Anyway, I hope they informed you about data loss? The mainboard contains the storage and if they say it won't connect to their computer and you can't power it on for a cloud back up then you will lose all data.

The phone powers on and off just fine.. I purchased a new charger as I had mentioned I think my other one was overheating because of heavy use.. They said the main board and charging port will be changed. The main board because it will not connect to Samsung's computers fo they could diagnose the issue.. I'm not worried about losing any data, as all my stuff is backed up...

Hi, did you still have this problem ? I was wondering about buying the samsung A52s or M52.
