I practically can't get my phone to detect theirs a computer connected to it at all. I've tried cleaning the usb port a few times and my pc detected it but it only read as "Unknown Device" and nothing from their and after awhile it stops doing that little detection. SO what can i do other than replace the usb/headphone jack piece? is their a way to enter fastboot and do that unbrick instead?
The replacement USB is only around $14, and it's an easy fix, take the back off, take off the black plastic cover on the top, has about 9 screws I believe? The bottom has to be removed as well, that has 6 screws, once you take those off, you unhook the LCD and the motherboard from the old USB/Power/Volume dongle, and replace it.
That being said, it's still time consuming, and tedious, but it is basically easy.
I would suggest to try another cable, and to try another PC as well, there was a time where my motherboard on my PC wouldn't detect my LG phones, but my wifes would, it's resolved now, but needless to say it was a pain .
Well, at least that makes sense now, i will try when i get the money and i've tried connected different cables and pcs and its the same result. not even linux will detect anything. But thank you for the help so far

well, I think I may have accidentally signed my wizards death warrant...
I dropped it at work today, and at first, everything looked fine, still worked, so I figured it was ok.... well, I was wrong, when I got home, I plugged it into the charger, and it wouldn't charge. tried another charger, still nothing... I opened up the back case, and the mini usb connector was snapped off the board.... needless to say, I had a lovely string of expletives...
The question now, is there any way to fix this without replacing the board its connected to?
For now, I'm gonna hafta go buy a new phone... this sucks!
I saw a thread yesterday, something to do with saving a dying breed, there was a guy in there that said he had loads of the usb bits, post might have been old but worth a shot...
YUP !
Its repairable,if you have good experience with electronics and gadgets and also have knowledge and worked with fine soldering,get hold of the service manual and can repair yourself.Otherwise take it to some Mobile repair shop,they can do it,no big deal.
Did the same thing. The usb on the wizard is honestly not soldered on well at all(mine was a definite cold solder joint). You may have just broken the solder and not the leads from the usb plug that go to the board. I, unfortunately, kicked mine while it was plugged in and broke the leads all together. I had my brother take an old phone he had with a mini usb plug and swap it out in no time. Long story short you can now swing my phone by it's usb cable, although I wouldn't recommend that!
YAY! lol...
well, its temporarily fixed(till this weekend, when I'll have the time and patience to solder it....
I used some automotive goop(really thick and heavy glue, I use it to glue everything...)to re attach the mini usb. this stuff sticks to anything and dries rock solid! The phone charges, but the computer is telling me that it cant recognize it. Hell, Im just happy that all I need to do is solder the damn thing on.... I thought I killed my beloved MDA!
I had a problem with my Nexus One's usb port, the pins got bent, and so I sent it into HTC for repair. Well they told me it would cost $250, and that it wouldn't be covered because they suspected user damage. (I never dropped it, my cables just stopped working and I noticed the pins were bent, so I don't think it's anything I did wrong).
Anyways, so I decided not to repair the phone, and I would just hook up a wireless charging system from the Palm Pre and transfer all my data using wifi.
Well, when I got my phone back, HTC was nice enough to relock the bootloader for me, so now I can't install cyanogen, and I can't unlock the bootloader because I can't get a USB cable to work.
Is there anyway to unlock the bootloader without a USB cable? Any help would be appreciated.
I would try adb wireless (on the market) or SSH into the phone
Edit: which, these only make sense (and I doubt either work) if you still have root, which is probably not the case
Yea you can connect ADB over WiFi - but you need the cable (or root privelges) to switch to wifi mode. You can try of them one-click root apps, then get the adb wifi widget.
I ended up getting a USB cable to work if I held it at the right angle, so I got the fastboot unlock, couldn't send a recovery firmware, but I was able to use ADB to send the files over and do a manual root, and then put a recovery on the phone. So I have resolved my problem. Next time I would be sure to not do any updates if they ship the phone with 2.2 on it.
I believe that they use a standard microUSB receptacle, which can be removed and a new one can be soldered, for a fraction of the repair price. Moreover, with tiny screwdrivers you might be able to actually correct the misaligned connector pieces.

Problem is that the leads that actually make the contact have probably popped off of the ceramic part that they are normally glued to.
This will make it very hard to actually use the cable without bending the contact leads backwards into the case.
That happened to me once with an older phone.
My Sony Ericsson Xperia X10 is 2 years old. The last few months, I have had problems charging the phone and connecting it to the computer.
In order to charge, I have to "wiggle" the cable into the right position. When I try connecting to the computer via cable, the phone appears to disconnect again within few seconds, and then reconnect - I am returned to the screen that shows the green android figure and that asks if I want to connect to the computer.
I have tried with a new USB cable. Charging gets easier (not so much "wiggling" required), but the problem with connecting to the computer is the same.
Does anyone know what the problem might be? Is this a hardware weakness, so that Sony should repair it? Or should I just buy a new phone?
Hardware Weakness
Should probably rephrase... Is this a KNOWN hardware weakness with this type of phone, so that it should be covered by the reclamation rights?
If not, the store will probably claim that this is my fault, or a device only expected to last 2 years, so that I have to buy a new phone.
Had a similar problem, solution?? Well is easy, if look (in your phone) into thd little microusb hole, youll find a little object like a sheet. Just move it. Up or down with a little screwdriver. Try the usb if not working move it upside down. JUST DO IT WITH CAUTION THAT PIECE IS TOO WEAK AND IS DANGEROUS. IT WORKED FOR ME BUT I CANNOT WARRANTY ITLL WORK FOR YOU

I've got the same problem.. but there is no sw solution (of course..), so you have to fix it manualy.. I wanted to do it myself, but there are too small micro ****s, so I left that... I'll try it later..
I just had the same problem as yours and I asked for a technician to solder a new USB port for me. And he did it, I no longer have this problem. It is a very annoying problem, sometimes when you're transferring datas, the USB would disconnect with a just a slight bump.
I've got this problem on my x10 also, but beware - it may be something as simple as the USB cable is worn out. I thought my problem was with the phone, until I used a car charger with it and it charged perfectly - no wiggling of the cable required.

Thanks for all the replies.
Unfortunately, it is easier to buy a new phone than to go through the 3-weeks process of having a service center determine if the problem can be solved and if it will cost me.
Fortunately, I'm able to use another phone to copy the data from my memory card onto my computer, before I switch to a new phone
To the last poster: As written, I tried with a new cable, without much luck.
hi
when i connect my phone with usb to pc it could charje but pc not recognize my device even in boot screen and its not change from serial yo usb
i do this with another cable and pc but it doesnt work
whats the problem?
tnx
could be dirt in the usb slot
could be a faulty pin in the usb slot
could be a failing usb slot (fairly common fault that the usb slot starts to fail , lots of threads reporting it - pretty difficult to repair unless you're a dab hand with a soldering iron)
1st - test on another pc, just to check its not some weird driver issue
2nd - have a really really good look in the slot, dirt gets caked into the bottom, , personally ive cleaned mine with a paper clip in the past (gets pretty grotty in my usb slot, , i run a lawnmower as one of my jobs, , get pockets filled with grass and i dont use a phone cover), but they're sharp and metal so i cant strictly recommend it, a magnifying glass and bright light will help inspect it.
3rd - gently try a little upwards and downwards pressure, if the pc suddenly recognises it but then drops it again when you wiggle, its hardware.

Hello everyone!
After finally getting an external battery charger, I've been able to use my Samsung Focus again.
I'm still, however, having USB connectivity issues.
Here's what I've tried.
-Reinstalling Zune
-Using other USB ports on my laptop.
-Using another computer
-Reinstalling the Samsung USB Driver
-Using a few different microUSB cables, including one from another Samsung phone
-Cleaning the microUSB port.
-installing WMDC
EDIT: -I've also made sure my phone's in Zune Sync USB Mode in the Diagnosis app.
When I connect the device, it says "Unrecognized USB Device Detected", I've tried replacing the drivers with the Zune driver, which works half the time, but it still has a yellow caution icon next to it. Saying things like "the device cannot start", "a request for the USB device descriptor failed.", and "device enumeration failed".
So now it's down to it being the software on the phone or the phone microUSB port.
I'd love to hard reset and see if it's the software, but if it's the port and I've reset, then I'm screwed.
I've searched numerous forums, including this one, and still haven't seen any working solutions.
EDIT: Also, I've noticed in the Battery Status app... it'll say "charging" for a few seconds and then go to "discharging".
Some specs:
Phone:
-Samsung Focus SGH-i917R
-Rev 1.3 on AT&T
-Windows Phone 7.10.8107.79
-DFT Freedom ROM [I guess it was a Rogers version]
Laptop PC:
-Dell XPS17 L702X
-Windows 8 Release Preview 6.2.8400
-Intel Core i7 2720QM @ 2.20GHz
-NVIDIA GeForce GT555M (3GB) @ 1080p120
-16GB DDR3 Dual Channel Memory
If anyone can help, it'd be huge!
And if there's anything I've neglected to mention, please let me know and I'll edit the post.
Thank you so much!
So I ended up doing a hard reset, and much to my dismay, it's still spitting out USB Device Not Recognized. It reset to the DFT Freedom (Chinese New Year) ROM I have on there, which I didn't quite expect... I'm wondering if that's the problem or not. When I get closer to my upgrade next month (Lumia 920, here I come) I'll likely get ballsy-er, and might even dismantle the phone and see if there's anything physically amiss with the port.
Still, any suggestions, feel free.
Have the same issue. Did same as you searching internet for any hints.
Have had this issue for 6months now, just been living with it and syncing files to skydrive and Gmail with WiFi.
I even took phone apart down to the circuit board level to see if anything noticeable or maybe connector or any components with broken solder. Hit it with some heat from SMT soldering iron to get a bit of reflow in that area, didn't make a difference. Ohmed it out as far as I could go thinking data lines were shorted or something...no luck.
I'm leaning toward this being a USB receiver chip level issue inside the Samsung Focus. Was hoping it would be something simple. Who knows, maybe that ROHS solder wiskering issue is haunting me somewhere in that phone.
FYI this issue came up around same time I had the repeated chiming issue. The one that only goes away when you do plug in the USB connector with charger or PC. Luckily haven't experienced that issue in 5 or so months. But did have it dissappear for a month then reappear again back then, so anything goes.
Note about 2 months ago I plugged phone into computer and it tried to sync up, zune popped up. I got excited, but after remove and plug in again, have not seen been able to get it back since.
I too am having the same problem.
First of all, be warned - if you decide to pull apart your Samsung focus, it's easy to do, but I found that the SMT port for the antenna is VERY fragile.
Steps to open it after turning it off:
1) open back plate.
2) pop out battery, sim, and expansion memory
3) take out the 7 screws.
4) with a flat blade (whether that be a screwdriver, flat tweezers, or even a guitar pick), insert it in the gap between the chrome and the FRONT of the phone, then gently twist to pop the "back" off.
5) You will now need to separate the volume buttons from the side of the phone (the plastic comes out easy enough).
This is a sticker back, and getting it off is hard and can tear easy.Take your time.
From there, there are several flat PCB sections that have multipin connectors hidden under them. They need to be pried off - they do not require a lot of force.
Now the big reason not to do this:
The f$#%ing antenna connector. It will pop off, but the connections to the mainboard are VERY fragile. I'd suggest pushing against it and use tweezers to rotate and lift the connector.
All that said, I've been looking for a cause for the problems you've been having - there is one other symptom you haven't mentioned, and this has been a problem for a lot of focus owners - the constant dinging. You may not be getting it (if you're phone is on vibrate, then it's no surprise), but every time the device "sees" the usb connection to charge, it Dings (at least, for me).
Yeah. I *want* to either fix it, or drop it in the toilet.
My phone is off any warranty already, and Samsung refuses to help. I'm not buying any more Samsung products ... and before this, I was humming and hawing between the Nokia 920 and the ATIV S (for the screen size).
