USB port issues

I am having issues with my Captivate's micro-USB port being loose. This is my second Captivate, and although it's still under warranty, the first one was RMA'd with the same issue. I never drop the phone while charging, etc, and I've tried multiple chargers so I really can't see why this would be happening. Both phones were 1008 versions, not sure if the 1008 is known to have this issue, or if I just have horrid luck. If anyone here can solder / fix the phone, I'm hesitant to go to AT&T again, as last time they made me go to the store and have the person working there verify that the USB port was not broken (luckily it still charged if you held it a certain way, and even more luckily I was able to flash stock before returning it!). Anyways, this phone is a refurb, and I did call and almost get it replaced as soon as I got it, as it had this issue slightly upon arrival, but decided it would be a hassle. It's only been about a month since the RMA, so I'm pretty sure that if I try now, they're going to get very mean about it, and possibly try and send me a bill for the phone, not to mention, the guy at the AT&T store will probably think something is up.
Any ideas are welcome, I love my Captivate, and I was just getting into develping on XDA :S

I actually found a fix to my issue. I actually was looking at it one day, and figured that in theory, it should be easy to fix, so I (CAREFULLY!!!) took a small knife I had and gently bent the inner part of the port up just a tad (it looked like it was too far down, and yes, I know it's supposed to be far down, but not that far), and it actually worked perfectly.

Thats weird... It kinda has to be what you're doing with it, since mine doesn't even have an irregular slight wiggle.
Obviously it could be just your luck but i doubt it.
edit: and who cares if the att dude thinks somethings up... its your $500..

Like I said, the second one actually had the issue upon arrival, but it was barely noticeable (the USB port would work, but if you moved the phone a lot, etc, it'd disconnect, then reconnect). I called in and talked to them, but decided not to RMA because it'd be a pain (in hindsight I should have...), and the problem just got worse.

Is the port internally lose? Or just when you plug a cable in it wiggles alot? Ive heard about people stretching the casing inside the port from alot of flashing (plugging in the usb). But if the hole port moves inside the phone thats no good lol. You should try to locate a nearby device service center and show them the problem and make sure you walk out with refurb thats fine. Dont worry about the people at atnt questioning it. Hell I use to walk in and just say "gps dosent work" and they would switch it out no questions.

What you said makes sense, the port looks like it's pretty sturdy, it's just that the cable wiggles a LOT, and it makes it hard to get it to even register.

I had the same issue but a new cable solved it

I also had this issue, i opened up the stock Samsung Cable end to find that two of the four wires had insufficient strain relief and broke off at the solder joints

Oddly enough I had issues with the first cable as well, but I replaced it, and have tried others from my current.

[Q] Jig vs. UnbrickableMod

Has anyone used the Jig that is available for this device? e.g., one of these?
http://www.amazon.com/Dongle-Samsun...JQ/ref=sr_1_23?ie=UTF8&qid=1329352013&sr=8-23
I want to know how it compares to doing the Unbrickable Mod.
http://forum.xda-developers.com/showthread.php?t=1333424
Specifically interested in what cases the Unbrickable Mod will recover a device where the jig will not. I can use a soldering iron.

Unbrickable mod will let you revive your hardware much better than a jig would. If you know how to solder I'd recommend doing that.

what FB says is right, i personally dont like messing with that small hardware so i bought a jig, its fixed all my bricks so far but if ur plannin on running some crazy stuff or testing roms then i would stick with unbrickablemod, like FB said.
P.S. - If ur like me and am not so confident in messing with small hardware, here is a cheaper one..

Well, I took apart my phone to look at the resistors and wow they are small. Put it back together and the phone can't see my SIM card. I've looked and cant find anything disconnected. This might be a problem...

I'm sure you've tried rebooting and all the usually suspects. Have you tried someone elses SIM? Here's the i-fixit teardown but you probably have it already. Good luck.

Did not try another's SIM. Can do that tonight. Would be very surprised if this were the issue though. Yeah, the ifixit seems to be the best site for finding good images of the phone internals. I suspect the little ribbon cable which wraps around the phone and plugs into the daugtherboard containing the SIM is loose. Beyond that I am kinda at a loss. I will work on it more when I get home tonight from work. Thanks for the response! I'll let you know how things go.

I would pay for schematics for the Galaxy 4g!!!

Hi again guys, so this morning i took my Galaxy 4G that was not charging the battery for some reason. And changed the charging port because i thought that was going to be it. Funny enough it didnt do the trick. So i checked, double checked and triple checked the solder points and everything was fine. I can read the 5 volts on the charging port pins but thats it. When i connect the usb to the wall, it shows like charging sequence is starting but then all of the sudden the screen will go off and thats it.
Ive been having a very similar situation with a couple infuse mobos i have, but just similar in terms of charging. If i put an already charged battery on the t959v it will turn on and work just fine. It even recognizes the debbuging mode. In fact after i changed the charging port i applied the unbrickable mod to the mobo and it worked perfectly. But still, battery wont charged. The infuse mobos wont turn on they just get stock in a bootloop. So please if someone knows about some schematic made for this phone or knows the route for those 5volts please help me... I would like to at least check the closest pins where those 5volts are supposed to go before giving up with that phone.

This seems like something bhundven, m4m4n or raverx3x would know... I would pm them . Good luck with the hardware tinkering.
EDIT
Asked bhundven for you. He said he hasn't found any .

No. If you find them, we would like them too.
But I doubt you will find them.
We do have the specification (user manual) for the s5pc110 (exynos 3110). but it is not specific to our phone.

Yeap, thats what i thought. I do have that for the i9000 and the original t959. I mean some pinouts i made myself using working mobos. But i dont have that for the t959v. And since the mobo is not working as it should i dont think i will be lucky trying to check pinouts on a non working mobo.

So, a friend brought me his galaxy 4g so that i could take it apart and check for the pins i was looking for. Shure enough i found them, but too unlucky it didnt matter. It seems like its either an ic or one of those resistors shorted. But anyways thanks guys
Ok people so im editing this post because ive found the solution for my problem. Guess what? So i decided to give it a try to the reflow blower on my soldering station. Since i thought it may have been some soldering points or something that had a lose contact. Well, it was!!! Now i have my galaxy 4G working again. Im going to open it back one more time and try to use flux so that i make sure the solder points are nicely welded. Never seen something like that on a galaxy phone but hey, It worked!!!!!!

I never charge my phone....I bought an OEM external charger that came with 1 battery and then bought 3 OEM batteries for $6.00 each.
This way the only time I need the port is to hook it up to the comp.
Just a thought

Yeah, thats actually a good idea to keep your phone working. But the thing is that i do have a bunch of phones. Many of them because i buy them from friends who have them and something is wrong with them(Phones). So i buy them cheap and use them to test things and have fun flashing or stuff like that. And that one was the case, in fact, i bought it because the phone wasnt charging. But i thought the solution was to change the usb port since i saw the + contact inside the port twisted. But i changed the port and it didnt work. Like i said on a different thread, i work with electronics on a daily basis so for me this is just fun...

Good day sir I noticed you said you have schematics for Samsung T959. Is this true? I am looking for schematics to apply the unbrickable mod with the xOM5 resistor. Do you have schematic for this? Can you please share?

Those of us with an interest in kernel development would still kill for schematics or board traces. Neither have ever surfaced, that I know of. I believe that the previous poster was referring to the various SoC documentation that has been out there, but that won't tell you where to put the resistor.
The SGS4G is pretty unbrickable as it sits, as long as you don't muck with the bootloaders.
If you still want the unbrickable mod, I'd search through these SGS4G forums as I think @bhundven may have looked into it or done it. Search is your best bet as I think he's taking a break from phone-dev work.

Kit Kat is out... Gimmie a break!

Actually, @AdamOutler did the modification for me, but I risked the sacrifice to make it possible for our device (SGH-T959V/W).

Yes, I'm currently taking a break from phone hacking. I'm working on my own mental health and focus on my work.

Well, i dont think youll need an schematic to apply unbrickable mod. To be honestm pictures attached by Adam look way too clear for us to miss it. Thruth is i have been looking for a couple mobos schematics and been able to find some. For example last week i needed the N7000 Galaxy Note schematic to find the sim card pinout for a customer who broke the soldering on the mobo of a N7000 Galaxy. Lucky enough i found it. So, search will always be our best tool.

Possible to flash radio / rom / anything with broken USB?

After I got my skyrocket, many of my friends and family also decided on the skyrocket Well, now it's up to me to make sure they're all in working order.
So one of my family members left her skyrocket in a bag of water for a while while she was at the beach, and it was completely unresponsive. I fully disassembled it (not my first time), dried out the majority of the water, then left the phone in rice for a few days. The good news is, the phone boots up and seems to work. The battery still works and it charges over USB.
The bad news is, the cellular radio does not work, IMEI comes up as unknown, bluetooth mac is "unavailable", front facing camera is also unresponsive. Really bad news: data/adb over usb does not register at all. A few more days in rice haven't helped.
The phone is completely stock. My first thought was that flashing a new radio might reset the cellular somehow, but not having cwm/odin makes that impossible. I can't seem to get the phone into download mode either because of the USB problem.
One thing that DOES work is the stock recovery. I can tell it to flash the official ATT ICS build, which contains a radio!
However when I try flashing it says.. "E: Short write of /tmp/sideload/package.zip (No space left on device) Installation aborted". Other zips "failed to verify whole-file signature"
Any ideas? My next step will be buying a used skyrocket with a cracked screen, and transplanting the working screen from this unit...

First off, please use the Q&A section for, you know, questions and answers. Don't create a new thread; I'm going to ask the mods to move this one instead.
Second, your issue is that the hardware radio is dead. The stock ROM only has a software radio included. To put it a different way, the stock ROM includes programming that tells the cell radio what to do. It can't fix the cell radio if it's broken, though. Unfortunately, based on the amount of damage you've got there, I'd say your phone is pretty much toast.
If you're completely stock, try to warranty it out. Just be up front with Sammy about what happened (because, in this instance, they will figure it out if you make up a story or play dumb), and the worst thing they can say is no. You might get a sympathetic rep who'll help you out. If they won't take it, you've already got your backup plan in the working SR.

Meant to post this in Q&A, woops. Too many xda tabs open trying to figure this out. Sorry about that
I do know the difference between the hardware/software radios... My thought was that while the phone was turned on and submerged, the software radio could have become corrupt... A long shot perhaps
I'll try contacting samsung, but somehow I doubt they'll cover it. Sidenote, do you really think they have a more sophisticated way to check for water damage than the internal water-damage indicator sticker?
The question still stands though, if anyone is interested. Even without a cell radio, I'd like to be able to root it for other purposes
Thanks for the advice
Tom

Yeah, based on the amount of things going wrong, it's hardware. If the software radio was corrupt, it would be because the internal storage had been corrupted, and your phone likely would not boot.
And yes, they can find water damage beyond the sticker. They can see corrosion plain as day when they open it up and look at the internals.
You can root it without USB working. Is your wifi working? If so, download GooManager off the market, then follow the instructions in the TWRP thread to get TWRP on your phone. Download a custom ROM to your PC, then transfer it to your external SD using an adapter/card reader so you can place it on the card directly (instead of going through the USB port). Use TWRP to flash the pre-rooted ROM onto your phone and viola. Unless there's a pre-rooted stock out there (and I don't think there is for SR), a custom ROM is the only way I can think of to do it.
Be advised, though, that because of the amount of damage done to your phone's internals, there's a better-than-normal chance that something won't work and you'll brick. I'm not responsible for your decisions or for the brick if that happens.
Long story short, just get a replacement SR.

Same thing happened to my girls Atrix. She gave it a nice bath in Green Tea. After shutting it down and pulling it apart I gave it the rice treatment for 48 hours. Booted but returned a radio error. Her USB port was working so I was able to root it and install a few custom ROMs on it. No change. So I would bet you actually fried the chip. Call Sammi and get a quote to cover the repair which will be a new mobo. They pay shipping both ways and are usually pretty cheap.

Heh, this is my mother's phone actually. First she ripped the screen ribbon cable on a nokia E75. Then she smashed her Atrix's screen, tried to fix it herself with a new screen, and managed to rip part of a ribbon cable... so it no longer has a working touch digitizer. Now she left her skyrocket in a bag of water. The girlfriend managed to crack her skyrocket's screen, which I replaced... I've also had to fix 2x nokia N95's, an N97, and a bunch of water damaged dumb phones over the years...
FWIW, the skyrocket seems to have the best repairability / internal layout of any of the phones I've messed with
The cracked screen skyrockets on ebay seem to be going for more than I thought, so I'll be giving sammy a call for sure

is there any way to access the internal sd card and remove it?

My mt4gs ended up bricking itself one day during a charge. won't turn on...tried every method to turn it on. Concluded that it's hard bricked. Only thing it does (every once in a while), is give me a dim red light in the trackpad. in summary, phone's dead.
One Problem:
I have crucial info stored in the phone's internal memory. I'm willing to sacrifice the phone (and any chance to unbrick it) simply for the data. is there any way I could open up the phone and access the internal SD card and remove it? Does it even use an actual SD card for internal memory? Anyone know? Thanks

im guessing the mt4gs uses emmc. is there any way to pull data off the emmc? even though a phone is bricked

the only thing I can think of is if someone has jtag knowledge and also knows where to make the connections. not even sure if you could pull info from the nand or if you can only write. this isn't the same as a computer harddrive and getting info of a dead flash device is trick (as far as I know)
id suggest googling to see if someone local has the ability. hey who knows, maybe there is someone who could restore your phone as well

Thanks for the response. Finding someone who has that knowledge wont be easy. I tried contacted jtag brick repair service but no response from them

Funny you should make such a thread...just had something very similar happen to my original doubleshot.
Was playing netflix out to tv, wasn't watching at the time my back was turned, and it just shut off and won't turn on.
Was at full charge, and swapped through 6 different fully charged batteries and couldn't get it to turn on...just a dim light in the trackpad, solid...no flashes.
I left it behind me, i am in long island, new york city this week putting it back together...so leaving things like the doubleshot behind was at the expense of things like the 14 gallons of gas in cans i'm carrying or the wealth of first aid supplies, so be a week bare minimum before i can get back to it.

Thanks, good times. I have a ton of first aid training, more tools then I know what to do with and a couple grand invested in 18volt batteries, so I can run my tools for days without power. Nothing like being able to cut a whole house apart while the power is out. ...and I like to be helpful.
Back on topic, though, I wish I knew what happened to my doubleshot. It just died out of the clear blue, was running fine until the moment it wasn't.
I haven't tried to plug it into a computer yet to see what I can see, but I remember seeing a whole lot of info on connecting to it and talking to the radio direct through linux pre-boot, so i'll exhaust all software avenues before disassembly.
I am well out of warranty now, since it's the one I got at device launch, so I do think taking it apart will be in my near future. Definitely gonna take a lot of pics on that.
As that ds was my first android cellular device, haven't had something like this happen before. Definitely gonna cripple my devving if I can't get it running again. Devving with two of the same device and seeing differences in real time in front of you is like the first time you hook up a second konitor to a computer. You just can't accurately articulate how much more productive you can be.
Definitely appreciate any tidbits of knowledge anyone can drop here to give a leg up when I can get back to it.
