[Galaxy S II Q&A, Help & Troubleshooting] moe.nassef:
If you are facing an issue with Samsung galaxy SII with fake charging and you think that it’s a port issue and you are willing to change the USB port for your device please stop and action the below steps 1st to make sure that its not a software issue

•	Take a backup from all your data in the internal memory

•	Wipe your device by dialing the code *2767*3855# in your phone app

•	Open the device in the download mood and flash on it a stock 2.3.5 OS

•	After that you’ll find your device working like charm

•	Don’t root your device in this phase, just flash it with a stock 4.0.3 and then flash it with the root from CF-root

•	After that you can flash a custom ROM and I recommend Resurrection Remix

•	The idea that you change from ICS to ginger bread that you will completely wipe everything in your device so it will be as if you are buying it new.

Appreciate that the above is helping people having this issue as I had it and now its solved.

The Original Post down there

Dear XDA team,

Appreciate your support on the below:

I’m an android user since 2009 I had many devices since that date ended with galaxy SII i9100 “international edition” 16GB

It was working fine from Dec 2011 till 4 days back.

4 days back the battery was 10 % and I plugged the original charger to the device and I slept for about 8 H, then I unplugged the charger how ever since that time my device is having the animation of the charging in the battery and its giving that its already plugged to the charger.. The main issue that I thought it’s a USB port issue so I tried to clean it with alcohol and with a tooth brush gently and nothing was helping... then I found that in the CWM the USB cable is working fine in mount mood so this means that nothing bad with the port so I tried to think about the ROM, I formatted the system drive and cleaned the kernel and installed the official software ICS 4.0.3 and I removed the root.. I still have the issue and its always giving me that the battery health is overvoltage I asked someone in the local warranty and he stated that there is some issue with water with the device which I know by heart that it was not effected by water.. I thought maybe because all the galaxy SII users are experiencing overheated issues and we spent most of the time in air conditioner here in Egypt so it can affect by heat and the condensation process but supposed that the device must have a failsafe protocol .. I have a good faith in Samsung but I found that the issue is still there and nothing was treated, someone told me that it can be a battery issue and you have to install a new battery and I did changed the same and I tried to put also the battery in deep freezer to lose its volts and nothing helped ..

Last trouble shooting made was to try to remove the battery and put the device in the sun to have any amount of moisture away and I let it about 3 H and also I put the charger in the device without the battery and I found it opening without battery as this was for me something strange.

Please share your ideas with me as I can’t find help from the warranty or from anyone and I don’t want to void my warranty by changing the USB port as most of people advised to..

Waiting for your kind ideas to help me with my poor situation

Sorry for making it long for you to read all the above but I really want to explain everything I did to help in solving the problem as I searched the internet and I found that many people are experiencing the same.

Your kind feedback is highly appreciated.
