I just bought a att sgs2 on craigslist.. mint condition but the something is wrong with the usb connector in the phone.. I've tried a few different cables and they all work the same.. nothing when I plug them in but if I push the cable hard into the phone's usb connector it will work. So I need to replace it or just start using an external charger. Anyone have experience replacing one of these? Any input would be greatly appreciated.
The USB port is messed up u will need to replace that small part but only a expert or Samsung can repair that or u can just use an external charger

lol, good luck with that. You're going to need some pretty legit soldering skills, IIRC. You might be better off just replacing the mainboard.
If your phone is less than a year old you can get it replaced under warranty.
It is a fairly easy repair if you have basic repair skills (no soldering is required).
The charging port is part of a separate pcb/ribbon cable assembly, which you can obtain from several on-line sellers (sorry, but I cannot post any URL's).
Also, there are several videos on youtube that will show you exactly how to disassemble the i777 (and r&r the part).

Thanks for that info. I've been concerned about the sturdiness/longevity of the usb connector on this phone since the day I got it. I've always been very careful with it, but things happen y'know. This is good to know because, even though it's covered by warranty, when/if mine decides to go I know it will be on day 366 of my ownership.

I tried using LGs oficcial firmware upgrade software on my P500. The process failed, but rendered the phone unbootable (why dont they checksum the entire thing on the phone betfore writing to flash, atleast for the boot section?). After a few retries with various firmware uploaders, "emergency mode" is gone as well.
I'm planning on buying either "RIFF JTAG" or "Medusa Box" to rewrite the flash.
I'm a bit uncomfortable with soldering 8 wires to the tiny JTAG connector on the mainboard, and would rather prefer to buy a plug of correct size, and solder wires to that.
Does anyone know where I can find such a plug, or what the socket/plug type is called? (the socket is indicated by the arrow on (I'm not allowed to post urls, google "7263653-post2.html"))
Mostly it is B2B support and you need special tools, SW and other things directly from LG and you have to probably pay for it.
You can check Service manual, if there will be something helpful (my signature) but I'm skeptic about.
I think it would be easy to soldier the wires as the pin to be solder are alternate (1 on top next at bottom). 1 = far corner pin from sim card. 2 = front of it.3 = next to 1. and so on.
Else search for 14-pin Target Adapter cable.
I found one but i dont think it will work without modifying it, its a female type connector.

Yay, soldering. Please post some pics if you make it working.
i think this should work. you will not have to solder the phone but the other end of cable.

More usefull info here but the adaptor will be of no use just the ribbon cable.

I guess the modifying part here will involve some soldering on the mainboard, which I'm trying to avoid. The connector looks like shown in the attached image. It is similar to the LCD connector, but slightly narrower (and obviously with different number of pins)
Yaa its a 14 pin jtag connector , can't find a proper ribbon connector to it. All the links I provide will need some mod but lets search...

Its a hardware which lets us flash rom directly to phone hardware. Costs around 100$.

If you ressurect it with RiffBox,you'll lose your IMEI.
You need Octopus Box for IMEI repair.
Or,you can just read the FULL from a working P500.
Soldering is not that hard. It was easier for me,to detach the connector and solder directly to mainboard.

Alright, so not too long ago i tripped on my USB cord while my phone was charging and it took out the little plastic piece inside the micro usb port that holds all the wires in place. I bent them back into place, and can still charge my phone, but sometimes it hard resets when being plugged in/ getting unplugged.
I took it to the sprint store, they said physical damage and I would have to submit a claim with a 150 deductable. Well, i know a micro usb port doesnt cost 150 so i orderd "HTC micro USB" jacks off of ebay with the intent of replacing it myself. unfortunately the ones i got were not the same; wrong size and shape, etc...
my question is, does anyone know where i can get the right usb jack, is it even available or do i have to bite the bullet and pay the 150? or maybe someone has an idea i havent thought of yet?
Just bite the bullet and pay the $150. You know it will be done right (you get a replacement phone) and it will still be under warranty. You damage it replacing it yourself, you might not be able to file a claim later.
Have you already looked at this website?

I would not recommend attempting to replace the USB jack unless you are skilled with a soldering iron. The surface mount components are not for the faint of heart. If you don't know what you are doing, you risk damaging the phone evern more.
GT-I9100, 4.1.2 stock. All of a sudden started getting this error when connecting USB cable to PC.
Note, I've been trying two different PCs (one with XP, one with Win7), different USB ports, different USB cable - same error. It charges perfectly fine with all these cables and port, but refuses to connect (Debugging on/off...you name it).
Any idea?
Thanks in advance.
OK......I think you have a faulty USB port (they DO wear out)......
Each connector in that port performs a different function. It is entirely possible that one of the connectors in your phones USB port is faulty (in your case, the data transfer connection) while the others remain functional. It is an easy and cheap part to replace.....
If you check my profile, you will see a guide I have written that explains exactly how to replace it.......

OK, let me understand something - so I need to disassemble the phone first to determine which version my board is, before I even order it, correct? In other words - no other way to determine which version/board I need to order...
Yes....afraid that is the case.....an authorised service centre would have to do it the same way (though they'd probably have every version of the board already in stock).....

hey man,
i had exactly the same with my phone. replacing the usb port of the i9100 helped. i paid 20 € for a new original! one (i think you can get them a little bit cheaper, depends on your location). be careful not to buy fake usb ports from china.
i was afraid of disassembling too. but with the video guide it is simple and easy. the most "problem" i had, was to open the cover. do not force it, be gentle. it takes some time.
you will need a very small screwdriver. you do not need a original from ebay, just go to the next walmart or whatever you have and buy one :good:
merry xmas!
Yeah....most DIY chains will do those micro screwdrivers.....hell, they even sell them in my local £1 store.......(though i imagine they're probably only good for a single use lol)

Did you check your USB cable is working. Because, there are cheap/fake usb cables out there which can only be used for charging, sometimes charging also wont work

Yes. Checked several cables, including the original that came with the phone. All of them charge the phone (in two different computers) but not connecting the USB (again, in two different computers).
My USB port hasn't worked for a few months. It was intermittent at first, but by now it's just dead. I bought a battery charger and a second battery, and just swapped them every night. Works well enough, but it's a PITA.
I've had my i9100g for just shy of 2 years, so it's supposed to still be under warranty (here in Germany, anyway). I sent it to the repair facility but they're giving me grief about running CyanogenMod. Note that the phone won't even charge from fully off -- it's *clearly* a hardware issue, but I don't know if I'll be able to talk them into fixing it. Otherwise, they want over a hundred euro to fix the phone (they insist on a full motherboard replacement), which IMHO is barely worth that new at this point.
If I can't get it fixed under warranty, should I try to get the local repair shop to replace just the USB port, or should I try to replace the whole motherboard myself? (I'm comfortable with disassembling fiddly electronics, but I can't do tiny surface-mount soldering.) Have any of you done either of these things?
Yes.I can change usb port/board in 5 minutes.Look at the you tube video that is posted in my motherboard thread.Also read 2 threads by duguet and keithharris about usb replacement.
You dont need to take out mb, just take out the mb screw closest to usb board to get room to pull out usb boards cable.The cable under the mb is stuck down with tape.
And you shouldnt need a new mb, someone is talking crap.
Thanks for the quick response. I didn't realize there was a separate daughterboard for the port; that should make things much easier! I think the service center said they'd have to replace the motherboard because that's the "approved solution" for running custom firmware -- what a bunch of assholes, seriously.
I think my plan will be:
* Try to get warranty replacement for the daughterboard
* If not, see what they charge to replace just that daughterboard for me (I already owe them 15 EUR for a "diagnostic" fee, which is waived if they do work, so it's a sunk cost)
* If that's too much, try to replace the board myself
ETA: I'm kind of embarrassed that I missed all the old posts about this apparently very common problem -- maybe I just didn't know what to search for, but it looks like this has happened to *at least* dozens of other users :-/
Or you could save yourself all that grief & just replace the USB board/port regardless. Will cost you a tenner, tops. As TheUnderling said, Keith's thread in General (search for 'replacing usb charger board' or similar as it isn't stickied) has all the info you need to get it done. It really is quick/easy to do yourself.

I'm getting the phone shipped back, FYI.
Anyway, it sounded like a lot of people had issues with getting not *quite* the right board, which tanked their signal / reception quality. If I can clean the plug and everything works, I see no reason to open the thing (other than just to have a look round, which is always fun ).
I think it started when I spring cleaned the inside of my desktop system unit and accidentally plugged the front usb 2.0 connector (my pc is very old) to the motherboard in reverse. I didn't recognize it until I tried charging my phone through the front usb but my phone didn't charged at all and it suddenly got very hot instead.
After that, my phone won't charge through wall or usb anymore. It only displays that the phone is charging but the battery percentage is not really increasing. I already tried replacing the battery and also tried using a different wall charger and it's still the same. For now, I've been using an external battery charger since it's my only choice and I can't afford to buy a new phone.
Can somebody help me identify what parts were damaged and I need to replace in order to fix the problem? Do I need to buy an entire board replacement just to fix this?
BTW, I'm using i9100 Intl.
Thanks in advance.
Replace USB board/port; quick/easy/cheap (<US$15) to do yourself. KeithRoss39 has a guide in General which will enable you to get it done; there's a link to it in Hopper8's Odin Troubleshooting guide stickied in General if you can't find it with a search.

Thanks for the response.
Are you sure it's only the USB board/port that I need to replace? btw, file transfer is perfectly working, charging is the only problem.
USB board malfunction has become a common fault with this phone (and to be honest, all Samsung phones). The board rarely dies completely all of a sudden, almost always shows a couple of faults but works OK in other ways.
Fairly sure this will fix your problem, and given how cheap it is, you might as well try it before you start spending serious money taking it to a service centre or local mobile repair shop. If that's not the problem, it's likely something else on the motherboard but as to exactly what, that's impossible to say without the phone in front of us.
Replace the USB board & see, given you've tried different batteries & charges, it points to the board/port.
The fact that your phone is functioning normally when you insert an externally (fully) charged battery would indicate that the problem isn't with the motherboard.
The USB charger/port board is connected to the motherboard and is pretty much the only part of the phone that separates the motherboard from the charger. As @MistahBungle says, everything points to that board being faulty, and replacing it really does cost pocket change and is something that is relatively easy to do.......
