I have a second hand Galaxy S2 which was unlocked to all networks and randomly the phone would connect to driving mode. I used GoLauncher EX to delete Voice control but then it started showing that it was charging constantly. After a lot of research I found the problem was in the charging port.
I ordered a new charging port online and I've put it in instead of the old one and now the charging problem is gone, but now my phone gets no service on a Three UK sim, I'm quite sure it wasn't on Three UK to begin with.
Is it possible that changing the charging port might have locked the phone to the original carrier again?
and is there anyway to unlock it(without root) or get it working again a different way?
(This is my first post. Forgive me if I've made any mistakes. )
Got quite a few views. Does this mean no one has any idea on what it could be?
Take a look at the antenna wire sometime you touched it and it's not connected properly
Yeah I have seen a lot of people lose signal who replace that port. I'm pretty sure it has something to do with the antenna. Make sure you have knocked it by mistake

I experienced the same problem with my Samsung S2. I had destroyed the charging port by being careless when charging it which meant my phone would not charge at all; although if I was lucky I would get about 10% charge every day.
To resolve the problem, I bought a cheap charging port flex cable off ebay for about £4.00 which I thought was a bargin. After taking the phone apart (with help from a YouTube video) I replaced the port, turned the phone on and it charged perfectly. Then all of a sudden I lost all signal. I moved around the house, hoping to get the slightest bit of signal but no, nothing. I did a lot of research online as to why this has happened and everyone said it was to do with the antenna cable that runs along the left hand side of the phone so my immediate thought was to buy a new one. I did a factory reset to see if that helped but it did not. As I was desperate, the following day I went into town to see if I could find a shop that sold an antenna wire. I went in shop after shop but nowhere sold what I was looking for. I went into a shop and described my problem to the man behind the counter, and he knew exactly what was wrong. On the flex cable there is "REV" followed by a number, and he told me that if the replacement number is not the same as the original then the phone will have no service.
In the photos you will see my original cable that was "REV2.3" and my replacement cable that was "REV2.2".
Long story short... when replacing the charging port make sure the replacement flex cable has the same REV number as the original otherwise you will have no service. Your problem is not related to the antenna wire.
I hope this helps!

Somehow the micro usb port on the phone (the charger) has been mashed up inside, i think it may have been due to someone trying to fit the wrong charger into it.
a shop said it'd have to get sent away,
i was wondering if their is a place to send it to get fixed or it it fixable ?
atm im having to charge another battery with a docking station and swap battery's because it wont charge,
it did work a little earlier on today, charging. but i can see the insides are pretty well destroyed.
it looks like the piece can be removed and a new one soldered on,
any ideas ?
thanks.
Honestly, if somone on here knows how to fix hardware issues I am sure they can lend you a hand but otherwise you will have to go to a repair shop and have it serviced. Just make sure that everything is complete stock and bootloader is in locked state just to be safe. If you don't want to send it back through the mail you can always take to a sprint authorized repair shop.
If you want to attempt it yourself here you go

Thanks guys, ive been looking online and some places seem to say they can fix it,
that video is just jokes, he faffs around with the thing im sure he ha no idea what hes doing.
ive found usb ports for other htc models just not the evo 3d.
ive realised it is quite a common problem
its charging via my docking station... just. obviously the internals of the micro usb are mashed up, and i know the replacement needs to be soldered on,
ive looked on some websites but cannot find anywhere to fix it.
its ok atm as its charging via dock, and i have a spare battery, also i can just take out my sd card to add stuff but it i rather annoying abd id like it fixed asap.
You could always use WiFi file explorer,of course WiFi is required but you can read and write the sdcard from your ip address,
Signature (Don't ask me for help, couldn't careless if your phone explodes)
strange thing is its connecting via my dock.. and charging, eventho the insides of the micro usb are mashed up..
it wont work with any other cable just in the dock...
im guessing the dock pin is slightly larger thus allowing a connection ?
Just replaced the charging port on my ATT SGII i777. Still not charging. Any ideas on what to try next?
The charge port I bought was for a i9100 but I was under the impression that they were interchangeable:
I've tried several chargers so I'm pretty sure it is not the charger,

Cable? Have you tried a different charging cable?I know it sounds ridiculous but I remember someone posting that fixed their issue.

Yes. Charger and cables. tried like 4 different one including two samsung ones.. I also plugged it into the computer and it is not detected at all.
After my original post, I noticed that my cellular service wasn't working either. Cleaned up the old port with a good dose of rubbing alcohol and a soft toothbrush and put it back in. Charger still not working but the cell service is back.
The markings on both boards say GT-i9100 and rev2.2 but the original says R.B82 and the replacement says says R.B84. I doubt that means anything.
Any other ideas or testing to do? Luckily I ordered an external charger and extra battery so I am not dead in the water.
Just a quick update - I bought several other charging ports before I finally found one that works. The one that worked was on ebay from muchbuy-outlet. I emailed them prior to purchasing. They said it would work and it did. Here is the link will expire at some point...

I tried this one from ebay and it did not work (can't post link so it's ebay item # 330880743336
Im thinking of trying the one you linked. Could I ask when you bought your GS2? I got mine about a mnth after it came out. If you got yours at the same time maybe ill take the risk of buying another board.

you know, I didnt use my i777 for 6 months, and I went to charge it and it wouldnt charge... It would just sit there with the captivate lights blinking rapidly like it wanted to start, and didnt... Long story short, I took the battery out of my i777 and used my t989 as a temporary charger just to get some juice in there (to about 10 %) and switched it back to the i777 and the i777 charged it no problem after that. I think there could be an issue with the i777 firmware which doesnt charge a battery that has gone to complete dead.
I have no issues charging or connecting to adb now

It is because the usb port that we have on our phone is not that great. Before I got my port fixed by Samsung, it would not be able to charge an empty battery, but now it is fine. Although sometime when the battery get too hot, it just through the phone in a loop of charging just enough to boot then shut down again.
You need I9100 gt model Rev 2.3 to replace sgh i777 At&t usb flex cable.
I just changed mine. Mine was rev 2.3. I got mine ebay at the "Cellphone-Repair-Shop" Search for "usb flex cable i9100 gt" model. It has to be the Gt model and it has to be The rev 2.3. So ask your seller before you buy. I believe the cellphone repair shop only sells 2.3.
I did put the Non-GT model in first because I read several reviews that it would work if I bought it from a specific store. This turned out to be a misplacement of many reviews. I am returning that one tomorrow. The wrong one charged for a day. Then nothing... and it caused all kinds of reception problems. Pretty much made phone useless.
Now with the Gt model in, when I connect to computer (wouldn't work before) it reads in explorer that this is a i9100 gt model phone. I do believe it is the new usb port that causes this to be read as a Gt i9100 and not the warning screen caused by rooting.
I wonder if this will cause any problems when flashing roms or anything else like otg usb mounting.

Bud,
When I plug in my charger the charging circuit goes on and off. I have a tone that dings once (or makes a "BEDUP' sound) indicating the charger is charging and it sounds like a bell indicating that the charger circuit connects and disconnect even before the BEDUP sound can fully complete! LOL Well instead of just one 'bedup' sound it bedups then bedups again! and again etc. The actual indicator on the battery icon goes on then off in sync to the bedups. I suspect its the dock connector charging port but am not positive. I have two I777's; the second one charges fine with the same usb cable so the cable is ruled out. I also had trouble using ODIN and getting my drivers to load in windows "Intermittently", but only on the SUSPECT I777.
Sometimes I can get it to charge by holding the USB cable either pressed upward or downward but it I change pressure at all it will go out.
Were the actual metal strips on your dock connector worn out? That is what I am thinking my issue is. If so It will require another charging port.
After reading your post an reevaluating my issues I am even more sure it is the charging port, but would appreciate any input you may have about your experience!
Thanks for your input!

Hey, thanks for the info.
My i777 device has the same issue. But the item in the above link does not ship to my country.
So I checked on ebay for another S2 REV 2.3 usb flex cable and found this.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140959296482
But in the cable you have bought it says "R.CB4 28 GT-I9100 REV2.4" and on my selected cable it says "R.CA4 GT-I9100 REV2.4"
Is that a big difference or should I not worry about it?
Thanks!

Sorry I missed this but anyone having this issue should first try cleaning the port with a small brush (soft toothbrush or I used these: http://www.dentek.com/product/144/easy-brush-cleaners/) dipped in isopropyl alcohol. That may help (or not). If that doesn't solve the problem, you are going to need to swap out the charging port. -- Bud

Hi,
So my battery stopped charging all of a sudden, and got drained and died. Since then, I've swapped batteries with a friend's S3 (US version, whereas mine in International), discovered that my battery's charging fine in their phone, and their battery isn't in mine, and I've concluded that my phone's micro-USB port might be damaged. I've tried both charging via wall and PC, with the charger that came with my S3, my friend's S3, and an old Samsung phone of mine (Samsung Jet). No computer detecs the phone when it is connected to it either. So my conclusion is pretty solid, right?
What can I do? I am in the US, and my phone is under warranty in Singapore, but I don't wanna ship it out for repairs.
1) Should I troubleshoot more to diagnose the problem or do you agree with my reasoning?
2) Can I get the micro-USB port replaced somewhere at minimal cost?
Thanks guys!

Had the same problem with my note. Just cleaned the port with a tooth pick (especially under that tight spot).

I'm amazed but it actually worked. I tried it the first day my phone stopped charging, and lots of fluff came out, but it wouldn't charge still, so I started thinking cleaning wouldn't help. But I tried again and again, actually going for ALL the tiniest bits of fluff instead of juust the big ones, and in the end it did work. Amazing, and thank god I didn't start unsoldering the micro-USB from the PCB. Thank you!
Hi guys,
So far I have used 3 chargers. A Verizon green 10ft long charger, the charger for my Nexus 7, and a Verizon car charger.
Basically when I plug any of these chargers in it will show it is charging for a split second, then it'll go away. So in order for it to charge, I have to push the charger in really hard, push it down, or bend it to the right. If I bend it to the right, when I let go, it stops charging. Sometimes I can get it at the right angle to keep it there, but I come back later and see that it isn't charger. Also if I push it in really hard, bending it to the right stops charging it.
The Verizon car charger has been the best for me (not as bad but I still have to bend it), but I use my nexus 7 charger for it most of the time.
This is super annoying, how it's real hard to get it to start charging and even harder to keep it. None of the pins on my chargers look crooked, nor inside my phone. I don't know if there is a fix for this, I might just take it to Verizon.
Anyone with the same problem or know of a fix out there? Thanks!

I've had that problem to and with my fiancée's s3, I need to push it in quite hard to get it to start charging but my girlfriends s3 I need to do almost the exact same as what you've described bending it pushing it, I think we where on our 5th charger for hers before it just refused to charge anymore it is definitely a problem with the phone we sent hers back and it was fixed under warranty, we were told by T-Mobile that it was a common fault with the s3 but it was repaired and now works perfectly, we have the international models. The only fix is it to send it back unfortunately hope this helps.

This is a Verizon certified phone. I only got it about a month ago. I'm a little scared to get a replacement. I actually had a Rezound before, and I went through 4 malfunctioning Rezounds and weeks of not having a phone before I called up verizon and they offered to switch my Rezound for a certified S3. It's great in all other ways, that's why I'm afraid to replace it with a phone that has problems with using the phone itself.
Okay, what is going on here. I made the cord tight and angled it to get a charge. It was at 42% last night when I started charging. I got up and the red light was still on, but the phone was still at 42%. It seems only angling to the right will it charge normally.
This is so annoying. So it's the charging port on my phone then? Maybe I should get the manufacturers charger, maybe I'm just using chargers not really compatible with my S3? Because my car charger works as soon as I plug it in. I mean if I turn in my car a lot it will stop charging and I will have to readjust the connection, but it's not nearly as bad as the charger I'm using at home.
Get it replaced and done with, mate. It's hardware problem. And not with the charger.

How long did it take for you to receive your phone back? I'm sending my phone to Samsung for repair. Sounds like it's going to take about 2 weeks, which is unfortunate. I just went through that
There is a simple fix!!!
I previously had to post this to a different forum so im posting the solution to this forum.
This issue can be fixed easily, you just have some stuff to fix it with. It's not only the connectors that's dirty, It's also the bottom of the micro usb port, it can easily be blocking the the connector from connecting all the way in. Here's how i fixed mine:
The first thing you'll need is some rubbing alcohol
Some Q-Tips.
The second thing you'll need is a very small sewing needle (go ask your grandma for one )
The third optional thing you'll need is some compressed air WITH a straw thing at the end
First off, remove the battery of the phone and set it somewhere.
Then get your sewing needle and dip it into the rubbing alcohol (helps clean the residue).
Then DELICATELY take the needle and clean ALL residue on the bottom of the port. Do this and make sure ALL residue is gone.
Then take the Q-tip and dip it in the rubbing alcohol.
VERY GENTLY take the Q-Tip and put very little pressure against the charging port.
Take the needle and go for a second try for the residue and let it air dry, OR get the compressed air and CAREFULLY blow out the rubbing alcohol and dust out of the charging port.
Put the battery when dry and turn on phone.
This will effectively clean the charging port AND the bottom of the port.
This has probably an 80% chance of working. It worked for me!
Plug it in and see if that works!
I'M NOT RESPONSIBLE IF YOU MESS UP AND SCREW UP YOUR PHONE!!!!!
I hope this helped everybody
Hey, I ran into a funny/dumb situation. I was on a trip and broke my micro usb port on the S3 and it was crucial for me to use the phone that couple of days (it was drained) so I found out that I can pin the wires from a regular USB cable (+ and -) out of my laptop to my battery while it was in the phone so it worked for a few times i got the charge. But then after the 5th(ish) charging the phone is not switching on... Yeah, I know, I probably fried my main board on the S3. The question is, is it worth to get it fixed? I really liked that phone though, I was not planning to change it until the S6 came out or something. Is it just waste of money and I should look out for a newer one or can fix it for a reasonable price?
Could you suggest something guys? Would really appreciate your help.
Thanks.
New motherboard is more expensive than a second hand phone would be.
