[Q] USB connection problem - Galaxy S II Q&A, Help & Troubleshooting

Since 2 days i have this problem.
When i connect my phone to the adapter it takes several seconds before it actually charging. But when it's full and i dissconnect it from the adapter it just keeps saying that my battery is full and i have to remove the charger.
When i connect my phone to the computer its keeps saying that he doesn't recognize the usb connecter.
What i have tried so far.
- Trying different chargers/cables
- Trying to update software but this can't be done without cable @ me
- Trying to clean up de usb port in the phone
- Battery reset
I have searched whole google and this forum but couldn't find anything related to this. so sorry if it's a repost

First up, do a factory reset. Back your stuff up before, obviously.
What rom/kernel are you running ?

When i did the factory reset it went in a bootloop for some reason.
I am using 2.6.35.7 codeworkx clockworck. I have rooted the phone and put clockworck on it nothing more... and it always worked fine.
I noticed something new. When i put off my phone you see the battery and next to it you see a yellow triangle with a exclamation mark in it. After that it changes into to a temperature meter showing it's to hot but i allready checked it and it's only 37 degrees.

First of all try the most obvious method such as turning on USB debugging. If that doesnt work go to the method below:
There is no need to do a factory reset. Just reflash your rom or flash a new one but make sure you have done a backup of your files. It worked for me

Sounds like the battery and/or the usb/charging circuitry/components might be on the fritz.
Try Steve's suggestion first (re-flash your rom or another rom), if that doesn't work, try another battery. Or even another charger. Tho you said you're seeing problems when you hook it up to a PC via USB.
If you get the same result after re-flashing same/different rom & with a different battery it would probably be a hardware fault.
I'd flash stock first & try that before restoring any backup, that would give you an indication of whether its a hardware issue (particularly with a different battery).

[Q] Suddenly stopped charging

I put my phone on charge last night and it seemed fine. When I woke this morning I noticed that it had only reached about 35% full. Neither the charger or usb cable are working now. I've pulled the battery out and left it for 10 mins etc but it's still not charging. Is this something I can fix easily or does it sound like it needs to go back to three.co.uk ?
Maybe your charger is defective!
I've also tried the regular usb cable direct to the pc and it isn't charging via that either.
I'm a worried now as I've installed a custom rom and I'll need to try to go back to stock if I need to return for repair. Trouble is that the PC isn't recognising the phone is connected by usb now :-(
Hmm, before giving it to service flash back the Stock ROM and see if the problem still remains or not.

Yes, if you have CWM use it to flash back to something stock. If you don't have it, you can get it through the app Darkysrom from the market. If you have enough power left that is..
I was wondering if I could flash back to stock with CWM which I do have. But as usb isn't being recognised I can only put the zip file on the external sd. Can I still flash from that?
I think you can.

[Q] S2 slowly dying

After a night time charge, my phone started to perform strange and I can't seem to get out of the situation.
It started with the temperature display showing on the battery when turning on. I am unable to start the phone, without it being connected to a powered on charger.Without a powered cable in, it just powers off, then goes back to the battery / temp display.
Upon starting, the phone runs fine, apart from the fact that it thinks there is something plugged into the USB port. This sometimes shows itself as the phone thinking it's still being charged to it thinking it's plugged in as a USB data connection.The USB port has been cleaned with the same outcome.
The phone can go from showing 0% charge to being flagged up as fully charged in under 10 minutes. Power the phone off and it will revert to charging as normal.
I'm unable to connect Odin to reflash as the USB port is detected as "unknown" device and I've tried this on numerous machines with the same outcome.
I'm unable to boot into recovery mode with clockworkmod, this coming up with the standard samsung boot options.
Is there a rom that I can copy over the phone, that will pass the Samsung validation check for ROM installation with the Down / power / action button combo.
I getting a bit frustrated with this at the moment, so any help advised will be great.
Cheers
Same thing happened to me, kinda, flash hyperdroid 4.0,you won't be sorry and it'l fix your. Problem.

Clean Slate for those that balls up the firmware or to eliminate hardware /firmware problems /return under warranty .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card .
Remove battery
Boot to download mode
Open Odin
Install correct stock firmware .
Still problems use usb jig to set rom counter to zero .
Return to service centre .

Cheers for all the info so far.
Things tried.
Different battery
USB port cleaned with isopropyl alcohol with both Qtip and new tooth brush.
Numerous factory resets
Battery left out for an hour for full reset
Wipes with CMW recovery with SD card in and Out
I am unable to connect to a machine, so I am unable to use Odin to reflash.
I've just ordered a Jig, so will try that as soon as it arrives.
I'll try the hyperdroid 4.0. Does that flash ok with the stock bootloader as the CWM recovery does not boot, even though the phone is rooted ok.

Well an update to my issues.
The Jig turned up today, after two inserts the usb port occasionally was detected correctly. This gave me enough time to reload the kernal.
After another Jig reset (successfull this time) I was able to connect to Odin and reflash the handset.
The battery is still reporting funny things (goes from 60% to full in 5 minutes or charges normally) so I'll be doing a few more resets / wipes and reinstallations to see if I get to a normal place.
Thanks for all your help.
I have the similar problem as yours.
From time to time the phone thinks its connected to USB.When this happenes I get a "Batery Overvoltaged" reading using Batery Spy App. And I can't connect to my PC using USB. The other thing happening is the phone is waking up as soon as I turn it off and if I try to turn it off again it freezes and u need to reset or pull the batery out. I though I solved the problem when I left the phone off without batery for 12 hours but that only worked for a day and now it started again this time it switches to driving mode on and off, and USB connection. I tried Hard reset ,reverting to a stable ROM with CWM , cleaning the port with alcohol, puting the phone without the back cover and the battery in a bowl of rice for 12hours(water damage?) , cleanng caches, battery stats, different kernels, removed the SD card.
I don't know what trigers this but it drains battery fast and I too had the batery going from 30% to zero in a flash and the fast charginng atleast once. Couple of times the phone even started by itself when inserted back the batery...
Please keep me posted with your progress, I surfed google and found this particular problem several times in other places so it happens more often than I though, but no one posted a fix, or atleast what is causeing the problem

[Q] Battery Issue

Hey, This is my first post so hopefully i didnt pick the wrong section to write in
So here it is.. A while ago my phone started acting crazy.. voice command started up.. turned off, started up again.. MTP started ( like i was plugging in USB cable) on and off and on and off again.. This was after i had rooted my phone for the first time.. but i was on stock rom at that point when all happend..
Now when im trying to charge my phone it takes like 30-60 sec till it starts charging.. same when i unplug the phone, takes 30-60 seconds for the phone to realise that there is no cable connected to the phone..
Can't turn off the phone.. when i turn it off its black for a few seconds then the samsung logo pops up and the phone boots up again.. and some times when i turn off the phone the battery logo appears and it shows that the battery is over heated..
This is what i have tryed:
- Re flashing, alot of diffrent roms
- Factory reset
- Format System, sd card, data
- Flash back to stock rom
Thx / Wrix
I remember seeing this issue in a few threads last year. Check this thread out as it lokos to be the same issues they were having http://forum.xda-developers.com/showthread.php?t=1174291&page=6
It seems some had to return their device and others were able to get it working again by cleaning out the micro usb port with a toothbrush. Worth trying. If nothing works, maybe you will have to return it. Hopefully not though
Thx alot.. Will take a look at the link you posted and see if there is something i can do to fix this issue.. hopefully i wont have to send it in to repair cuz i have rooted it.. dunno if samsung can see that if i use USB Jig ? hopefully not but will try with toothbrush to see if it works!
Again thx alot for the advices
EDIT: Toothbrush didnt work at all ;(
/Wrix
Just make sure you reset the counter and you should be fin returning it.
Your device should still be under warranty. I'd wipe, flash the stock ROM that you had on it when you bought it and use the jig if you have one. Then see about getting it returned. Good luck!

[Q] Hardcore battery problems (Complicated)

I have the same problem like month ago (Last time i solved it by new battery and everything was ok.)
I CAN'T CHARGE MY BATTERY.
My steps now:
1. I bought new loader and loader seems not to be problem
2. I have fully formated system, cache and everything that was in CWM possible to format and wiped all caches, battery stats etc and then I flashed stock ROM.
NOW:
I'm charging it with loader and i have all time 0%-5%.
I inserted for fun my old damaged (probably, but who knows where the hell is problem?) and it was 95% (LOL?) but after restart it died.
Where the hell is the problem?
With battery?
With micro-usb port?
With other hardware?
Maybe it's something wrong with system but I'm total newbie, tell me all steps how to check is everything there ok.
How to PRECISELY DIAGNOSE what the hell is going on?
Try hawkerpaul's nuke : http://forum.xda-developers.com/showthread.php?t=2100558
If there is a problem with the port, you can search youtube to clean it ( i don't think so tho)
Are you using the stock rom? If not, flash the stock rom with odin, try ICS rom too, there is no way we can check what is wrong, you have to try everything :/
Good advice from @Dakura except that you should stay away from Odin until you've ruled out any possibility of a faulty USB port. If you attempt a flash with a faulty port, you could end up with some really serious issues. If you want to replace the board (it costs less than a replacement genuine battery) read my guide........
http://forum.xda-developers.com/showthread.php?t=2335961
it should be of some help to you......
Edit.....if you choose the ICS stock firmware, stay away from 4.0.4......search emmc brickbug if you want to know why......

I put on my phone different baterries and it always shows different percentage. Cleaned micro-usb port and nothing changed.
@edit: i went to service and they have montage new micro-usb module, we will see what will happen

[Q] Empty Battery Bootloop

I had a recent soft bricked due to some "unknown" problems which I couldn't figure out.
Anyways,I was able to boot into download mode and successfully flashed the stock jellybean firmware via Odin.
Now the problem is that my battery is empty and the phone is stuck on an what I think is an "Empty Battery Bootloop" was the battery icon blinking every 5 seconds or so.
Any ideas how to revive it ?
PS : I am unable to boot into recovery as well.
I have attached a screenshot of the issue I am facing.
Ur screenshot says... 404 error
Re-linked.
Maybe something went wrong while you were flashing the ROM via odin. First of all did you tick Only the right options while flashing in odin?
Supposing you did,
1. Maybe the ROM file which holds information for your battery might be facing curroption.
2. Maybe the kernel (the default one coming with the stock ROM) was not flashed properly.
In either case, I would suggest trying to boot into download mode and try to flash the whole thing all over again. If the problem persists, flash a different kernel/ROM or both.
II'm pretty sure that should fix the problem though.

Tried flashing via Odin for like three consecutive days.Still no luck.
I have googled it and found out that some users were facing the same problem when their battery was completely empty and the phone wont start because it didnt had enough juice to boot up.You know how to solve that problem?

Just keep it on charging wid 0.7mA or a 1mA charger for few hrs... if still it doesnt work..use a usb cord to charge via lappy...
Also use someone else's battery to boot up... and make a wipe data via stock recovery
Charged with USB for about 4-5 Hours.I cant get hold of a 1mA charger here.Using another battery is nearly impossible for me since none of my friends seem to have a S2.
Any other phone which has a battery identical to ours? (Or a Samsung phone with 4 pins possibly.)

Nope. Don't try a battery not designed for the device. Asking for trouble.
Time to change it with a new battery or hook up with an external charger?
PS : Took it to a local mobile repair shop and asked for a universal battery charger.
When I gave him the battery,the first thing he asked was if the phone ever got wet.
He said there's some I don't know what on the battery due to licking it.
I recently replaced the charging circuit from a trusted Samsung shop and he says it's totally fine.
Seems like some kind of corrosion on the battery.Any ideas on how to remove it ?
Anyone ?
