[Q] I9100 charge without usb port - Galaxy S II Q&A, Help & Troubleshooting

Hi there,
I am looking for a way to charge my i9100 without using the usb port, as it is broken. I do know some phones have external charging pins hidden under the battery cover - my wife's Nexus S has those. Nonetheless I couldn't find them on my Galaxy S II. Anyone had some experience with this? I do know one can buy and replace the usb port together with the whole bottom circuit board, which would probably fix my problem. But I got the phone for free to use before buying a new one and I did not want to put any money into it

Hi namarath,
I have the same problem. The usb flex cable I bought to exchange the broken one was broken itself, which is common. As a solution I bought an external battery charger for just 5 Euro on Aliexpress. Works fine since I have two batteries. The indicator light switches from pink to blue when charged. Be warned that this light is bright like disco lights
Cheers

Buying a broken replacement USB port/board assembly is NOT common......buying the WRONG version of the board IS common....There are 4 different non interchangeable versions.
See this guide that I wrote for explanations.....
http://forum.xda-developers.com/showthread.php?t=2335961
But yes, I agree, an external charger and spare battery is a good option....I have done this for both my S2 and S5......

Hi keithross39,
Well, unfortunately in my case everything but loading the battery did work with the new flex cable which indeed had the same version number. So I was one of the few to pick a broken one But thanks for your work in that area!
Cheers

how to find out if usb port is defect?

Hi guys,
I've just received a - what looks pretty brand-new - S2 here naked and without its back cover. It's branded.
I also own a rooted i9001 (S plus) with themes and stuff. Still works like a charm.
So the S2.... I am pretty sure I can use same usb cable from the S plus and also the charger (Samsung Travel adapter 5.0V=0,7A) that both are working fine with the S plus.
However, usb with the S2 PC isn't recognizing phone, no matter what I tried. Only connection possible is via Kies (only wifi) and not explorer
The charger isn't recognized by phone either. I'm not sure if the USB port is dead because JIG tool is working. The battery I have is some Chinese one with own charger. The I read the S2 needs more power.
Suggestions anyone?
Thanks.

What do you mean? The phone charges but with charge rates limited by PC USB port instead of AC wall plug? Or doesn't it charge at all with the charger?
Or: how do you mange to charge the phone?

Hi, thanks for looking into my prob.
No, it doesn't charge when connected to PC via USB. The charger doesn't work with phone directly, no.
I bought the replacement battery off ebay and with it came a battery charger (wall plug). So battery can be charged aside from phone.
Unfortunately, I don't have any friends with original S2 accessories to test.
But why does the Jig work (if the USB port were broke)?

The Jig does not use all pins of the USB connector. Basically the Jig is a 300k resistor connected to the GND (5) and ID(4) pin of the USB connector. The pins used for charging are GND(5) and VCC(1). A bold guess would be that the VCC pin of your phones USB connector does not work.
You should consider buying a replacement flex board on ebay. It is very cheap ($10 to $16 I believe) and you should manage to install it yourself.

I got the flex board off ebay already. There's a nice guide on youtube.
Ah, ok - you were quicker.

If you are looking for information about how to replace the flex print then youtube is your friend
Just to let you know. I got new usb board, exchanged old one (that was clearly water damaged) and the phone now works like a charm.
OT: I've also noticed this trend on Ebay for people to buy non-functioning or damaged S2s. From the guides on youtube I can see exactly why.
However, it's getting pretty ridiculous now that non-functioning S2s with broken screens fetch as much as € 200??!!! I mean, come on!

[Q] Charger Not Working for Note

I've got 4 different car chargers that *used* to work for my Note. I know they worked, because I did quite a bit of work over the last year which required the use of the GPS on my phone. Each one is > 1A. However, recently they've all stopped working for my Note. I've tested them using a Galaxy S3 and a Desire HD, and the chargers appear to charge the other phones just fine.
I seem to have no problems with AC or the computer charger it however. I've also taken the same USB cable I've used on the AC/computer and plugged it in to 3 of my car chargers, still no luck. Any ideas?
Your charge port needs to be replaced. If you're still under warranty, get it replaced. Otherwise there is a guide around here to DIY replacement I think..
I think we need more info. Since the phone charges at home the first suggestion is not helpful. The port is fine or it wouldn't charge at home. What ROM are you using? Did you try flashing a different ROM to test the charger in car? What were the results?
get a toothpick and make sure the metal in the port isnt touching any metal , then try , these ports in samsung phones are cheap , my wp7 focus had this happen , if it doesnt work ,its easy to solder it back in place , just open it up and make sure the solder is correct!

The day after my post the AC charger stopped working with my phone as well. So after trying a couple more chargers, I took it into AT&T and got it replaced under warranty. However, since my wife and I both have the Galaxy Note, I may have to replace one in the future. Just in case someone needs it..

Very weird charging issue with my Samsung Galaxy S2

My Samsung Galaxy S2 has this problem.
A: I doesn't register the charge in the socket unless I wiggle it around or put pressure on a certain area. It's sensitive and it takes me a while to make it 'stick'.
b: It only charges to about 30% and then it stops charging.
I have tried numerous chargers and usb cables and always the same issue. I have replaced the battery and its the same problem.
Any help? I bought this damn thing on ebay a few weeks ago so I don't really know its history. The seller refuses to refund and I've opened a case.
Anyway that will all take a long time.
Any idea what the problem is and how to fix it?

Try Charging the battery externally using a battery charger, and not from inside the phone....I suppose it should get charged 100%...
If not then its battery problem...
If it does get charged then there might be a problem in the port or connection to the battery via inside the phone...get it checked at a samsung customer care...If you have warranty you might get it fixed for free...
I don't think there should be any problem with your kernel etc..
Press Thanx If I helped..
Try cleaning the micro USB port with a toothbrush or something similar
This type of issue is not weird and has been discussed on forum plenty of times.
Clean the battery contacts on battery and pins on device with alcohol (cleaning alcohol). If that doesnt work and you have changed charger/battery then your hardware is faulty so nobody here can help.

New Charging Port - Still not charging!

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

[Q] Galaxy S3 (i9300) won't charge

So I got this strange problem where my phone stopped charging. I tried diffrent cables, adapters, charging it while being off, charging it via the computer and even tried to adjust the little lip in the micro usb port. Is the charging board dead? If it is, will a replacement be expensive?
Sent from my Galaxy Nexus using XDA Free mobile app
Well dude I think your assumption is right.
It might be the charging circuit only which may be dead.
Because as you told that you have tried diffrent cabels and chargers but still your charging is not working which means that the usb micro port through which we charge and connect our phone to computer is damaged and should be replaced .
There are many possible reason of damaging usb port like you may have drop your phone or by using faulty cabels and chargers or if u have rooted your phone then there is possibility of changing the voltage of current to more than 1000 Mhz etc etc.
You should try to flashed a complete stock rom by downloading from sammobile or directly using kies to update or re-flash your phone
you can try that may it may help you.

Nah, it won't turn on because the battery is empty.. I don't have a spare so it seems buying a new board is my only hope..
I saw there are loads of micro usb connectors on ebay. If I solder a new one on. Might that help?

You can try micro usb port which is available on ebay but it would be extremely very dangerous until and unless you know what you are doing.
My suggestion is to give your phone to the samsung care and tell then to repair it.
If your phone is in warranty then they will do it for free. You just need to provide them a copy of bill at the time you purchased s3.
Press THANKS if I helped you
