Phone won't detect usb connection - Captivate Q&A, Help & Troubleshooting

I've tried multiple cables, and my cappy won't charge or sync to my computer. Is there any possible repair or anything I can do besides charging the batteries separately?

You could call samsung, and try to get a replacement.

I got it off ebay, so I don't think that's an option.

either the usb jack inside ur phone which is attached to the pcb of ur phone is having connectivity issues...
solution- if u r techie..then open the phone...look for connectivity issue around the usb socket and the pcb..and use soldering machine or blower to connect it..
or the fine 4 metal lines..which connects the cable pins to take charge or sync is rusted or having some dust accumulated..
solution - if u can use a very thin pin and try to rub that inner 4 metal connectors of usb socket..that might work..but be very gentle and do it with patience

I'll try the second one, but I'm definitely not qualified for the first. If there was someone offering the service pro a price, however, I would be very interested.
Also, my jig gets me into download mode. I don't understand...

The way the phone knows where its connected is setting a preset amount of resistance (301kOhms for download mode) on a specific set of pins. That just means the connection betwen 4th and 5th pin is relayed correctly on your phone.

I know, but that means the whole thing isn't busted... right? Are the two pins used for a jig unused for charging and syncing?

I don't know. I do know there's a schematic on the resistance combination somewhere around the forums.

I could do both the thing for you for free....because I am capable of doing both...
But sad news..Iam far from you
And yes jig only works on 2 pins...rest of the pins not giving connection..so I repeat..either cleaning those pins..or soldering those pins will solve the problem...and yes you should try cleaning with patience..as I mentioned in my first post

Charging fault?

For a few days my phone hasn't been charging, and at first I thought it was a problem with the battery, but having bought a new one I've realised that when I tilted the charger to the left it would charge, but when it's just left it wouldn't, so I guess a bit of a miss-alignment.
Anyone got any ideas how I can fix this problem?
Cheers, nathaniel
try another cable and make sure it's the one that came with the phone. you should have a usb one and a ac adapter. if both are like that then you need to warranty it out.
Yeah, Ive tried it with the USB cable and the charger, I got the same result. Is there no quick fix, I'm going abroad in 9 days and quite need my phone...
There are a few discussions on bad USB connectors in these forums -- searching might provide some things to try.
From what I can remember, it's possible the pins in the connector (on the phone side) might be bent out of place -- you might want to inspect them with a magnifying glass and try to carefully bend them back if any seem out of place.
It's also possible that the connector itself is broken -- in which case you're looking at a service call.
this seems like the problem i faced. i was also facing the same problem and i read the forums here and found it as a usb port issue. so i slightly bent the usb port so that the contacts are aligned and then it started charging
Hey I would also recommend trying a new a new charger again because I have had my share of faulty chargers. Last time I had a problem charging was with a brand new cable that did not work right at the box from At&T and thought it was my battery until i tried another charger that worked. I would suggest trying the charger that is not working on another phone and see if its actually the charger or if it is your phone that is not working.

I think it is to do with the pins in the connector.
I had a search but I'm not very good on forums and I can't find anything of any use. Does anyone have a link?
Just look at the last few pages of topics, you should find something... there are threads about broken USB at least once a week.
One common conclusion is to avoid using USB cables other than the supplied one as their
plugs are a little thicker and tend to deform the phone's plug over time (I admit I always use others though, and as a result do sometimes need to wiggle the cable a tad and not move anything anymore once the connection is established... ).
I once dismounted my Hermes and tightened the plug back a bit, it helped, I've never done it with my Kaiser yet though. If you're not used to dismantling and fixing devices I'd recommend returning it for repair indeed.
I had a the opposite happen, it would charge but no data connection with my pc. If you look at your extUSB port on your phone, see if the black plastic tab is cracked (which was my case) or if the pins are shifted. whatever the issue, its obviously hardware related, take it to an At&t service center tell them whats wrong and if your in warranty they'll change it on the spot.

He got the same result using his USB cable so that would rule out the charger.

Im in England, took it to the T-Mobile shop, the service was rubish and without even looking at it they send I should send it off which would take 2 weeks. There is a crack in the black plastic tab

Kaiser broken usb port

Hi, I've broken the usb port on my Kaiser, making it impossible to sync or charge. Can this be repaired?
How broken is it?
Is it just loose or do you think something else is wrong (e.g. bent pins, etc.)?
I would take it appart and take a look if I were you.
Maybe its the USB Cable....did you try another USB Cable?
I tried another 2 cables, as well as the AC adapter charger - it's definitely the Kaiser. It's to do with the pins. To elaborate (I was hoping not to, but....) I was in bed, lights out, and I wanted to reset the Kaiser, so I was trying to insert the stylus into the little hole by touch (no funny business, honest) and I'm sure I pressed it into the usb port a few times by mistake. So at the very least I've bent or broken the pins.
Well, I've rung a repair facility taht does HTC products, and the person on the line said that if it was just the connector, I'll be up for AUD $110 (I live in Australia). But if it's the main board, then I will be up for AUD $590!!! If it's the latter, I may as well by a new one! I'll have to send it in to find out.
Mine had broken pins...hTC told me that the usb connecter is part of the motherboard and that the board would have to be replaced for $389 (US). I ordered a new one from AT&T (cheaper + rebate!).
Now have a back up that I can use for parts, or charge the battery in the new one and put the battery in the broken one! I can play with ROMs and radios on the old one
AND, I now make darn sure the stylus goes into the reset port rather that the mini USB port.

bluetooth synch and external battery charger
I have the same issue here, my htc felt down and since then it's very tricky to synch via usb and sometimes tricky to charge up the battery.
So I'am now using the bluetooth connection to synchronize with my PC . I also bought before that an external battery charger for the tytnII on ebay from ecell for around 4 euros . I also bought a second set of battery for around 20 euros.
the tricky part is to succeed in seting up the bluetooth connection the first time , but I don't know I eventually manage to do it after several tries .
But of course now I won't risk any rom update or whatsoever.

Note won't charge

Looks like my USB port failed like others have reported. Tried different cables and even my girls sgs2 charger nothing. I know mine works because it charges her phone ..
Tried rebooting and pulling battery but doesn't show its taking a charge? Wtf...
Any suggestions? What do u do? I bought it used and I'm in the us....

And buy an extra battery so that you have one charged while the other is in the phone.
How about transferring files from computer to phone and vice versa with the usb cable? Does that work?
Hate to say it, but this is hardware fault. I've had the same issue. It is weakness of the USB connector plate. Mine was quickly replaced.
You can try to push carefully the plugged cable and connector down - in direction of the battery cover. It helped me to charge the device a few times in order to flash back stock ROM and claim warranty repair.

Good luck !
Mainly i was asking since I'm in the USA and bought my note used. If it fails (and i know its hardware) what's my nest route for getting it fixed?
I was able to get it to charge by pulling spen out and it showed charging icon. Put pen back in and it charged over night???
Really weird?

Might sound wierd but i had the same issue after downgradibg from ics. I know how this soubds stupid but a combination of downgrading, flashing custom 4.2 kernal, and restoring titanium backup. 2 days i ciuldnt charge my phone with 10+ chargers i have.
After formatting my sd, flashing full wipe and starting fresh everything went back to normal. I couldnt tell you what happen.
I was getting dock mode, vlingo and charging on/off flashing across my screen when plugging in charger.
If its harware and you cant send in for warranty. I would suggest opening the phone and taking off the speaker part. Youll be able to see if the charging port is loose or any dirt etc is around. The charging port is $5 on ebay and i think requires soldering.

This is what you do. take the battery out and then take a plastic edge like credit card type edge or even a plastic screw driver or maybe a real metal small tiny screwdriver and push the USB pin strip inside the usb port inside the phone. Not down or up but push is straight inside without bending anything. meaning: apply enough force but don't try to destroy the usb post inside the phone. This will most likely solve your problem. now take a look at the cover of the phone you have bought. make sure you cut the opening of the usb post on the plastic cover so that it allows the micro usb cable to connect without any hindrance or difficulty. I think my phone cover had a small hole in the flexible after-market cover I had bought. I didn't allow me to fit in the micro usb cable to connect easily. I had to push it in, in a slight angle. maybe this is what loosened the usb port pins inside the phone.
good luck. if all fails, buy the usb port for your phone on ebay. type in samsung galaxy note flex usb port and you will see listings. It should take you 10 mins to change the port inside the phone.
Hi every1. I have got a wierd fault. I cant charge my phone but can charge external battery charger with usb lead only via laptop...... Anybody got any ideas as to fixing this...??? I have 2 batteries and have to swap and charge them every day.
Thanx.

Got a really messed up USB port on one+ year old Razer 2

1) Can't charge while it is in normal mode.
2) Can't charge with USB C to C
3) Can only charge using USB A to C, while the phone is turned off. It still splashes the logo and vibrates repeatedly.
The port is not visible to any laptop, so adb and fastboot seem out of the question.
The stock recovery on this device has "apply update from SD card", so I need to figure out how an update.zip should look like.
Razer have a bunch of older stock ROMs on their site.
Can I just take the latest, rename it update.zip, put it on a micro SD and use the stock recovery to fix things?
Just saw the tear down. It's worse than my N10+ port PCB to replace.
However if the battery is getting near its lifespan maybe now is the time as the battery needs to come out anyway to replace the port PCB.
The port PCB price is probably low.

The other thing I just found is that when I use "apply update from ADB" it used to complain about init.usb.rc, init.usb.configfs.rc. I looked at both files. 0B length with 1969 date on them. What?
There must be some way to flash a recovery from the sd card instead of using the USB port.
The thing is the battery held the whole day after a night charge yesterday, so probably not the battery. I have a feeling some apps I used to "improve" the battery and "fix" the system deleted some bits.

They can cause a lot of mischief and in other services that you never expect it to.
The battery is cheap so it's easiest to replace it at the same time as you need to pull it anyway.
200 or more full charge cycles, replace.
One more thing. I bought a wireless charger to see if it is 100% the port, and the wireless charger has not made anything easier. It seems not capable of getting any charge in. So at the moment I have only one to charge it, turn it off and use USB A to USB C cable.

Probably a defective charge port PCB... you can try a factory reset or reflashing the stock firmware if really want to test it.
Check for any signs of battery (rear panel or display bulging) swelling; replace battery asap if present! Batteries can fail at any time.

I have now done the factory reset, didn't help. Nothing is bulging. I would like to flash a fresh factory ROM, but I have no access to the port. So, no fastboot and no adb. I can't even install proper drivers in Win10 PRO since the laptop does not recognize the phone, at all.
I am searching now for any solutions with the sd card. People used to do that, updates with *.zip on an sd.
Since it is out of warranty anyway now, I have finally unlocked the bootloader.
I am trying to find out if the ROMs Razer provide on their site are signed or not.

I don't know if you have had a chance to see the USB port assembly on Ebay? Some prices are close to $120. Add to that labor costs (unless you think I should do the deed myself) or costs for tools and fresh adhesive for the plastic that covers speakers, etc... and it is going cost me more than I paid for it new.

Ok, thank you for finding this, but it looks like the ribon connector wire only. The PCB besides the port also has the microphone, I think. It appears to be sold as a unit. If the problem is the wire, then sure this would be the part.
In any case, I have managed to get the wireless charger to charge. Depending on how fast the charge will be lost today will tell say something about the battery.

Unfortunately replacing the USB charge board and port in the phone doesn't always fix it. I have a box of nearly a dozen RP2 main boards I need to dig through to figure out what the actual cause of the charging boot loop

Have you played with any OS shortcut apps on it?
The Android Setup apk will get screwed up if you access it after the original setup.
Specifically it will alter the port behavior when you connect with it. Very irritating, took me days to finally track it down on my 10+
If you clear it's data in settings it may leave the null mark that's screwing it up. Some 3rd party apps can completely clear that null mark.
Otherwise factory reset.

This is a hardware issue, nothing any kind of reset can fix or app clearing. Even if you have the device entirely powered off, plug it in on anything 2Amp or higher, it'll loop

That's not how the issue I saw behaved; only happened with the device powered on and it didn't boot loop. Just an annoying pop up message.
If it has a port PCB, try replacing that. If it's just a charge port with no components on it... it's likely either corrupted firmware (reflash) or a mobo failure.
A loose connection or bad contact is also possible.
That's my guess...

New guy, coming in hot...

Need advice from PPC-6700 folks on VZW XV6700. its currently wont take charge via the usb on bottom. i purchased new battery and most i get is phone turns on for few seconds and shuts off after it hit home page. and the light does not turn red when plugged in. it was working fine up until last week.​
Maybe a bad usb port pcb. Could be a failed mobo.
Meh, bold type not needed...
Thanks for quick response. Im relatively new to diy with phones. is replacing the usb on this device something id be able to do myself? without possibly causing more damage.
Look at a tear down vid. It may not be the port pcb. You sure the battery is good and connected properly ie no bent connector pins?
No loose ribbon cable connectors?
historically that battery was never secure based off the design itslef. i may have bought dud battery... id need one more to test that theory. i have 8 different cords ive used and nada. its the old half octogon looking ones. they aren't prongs like the ones now.
I can open it up and send pic. Maybe you will see something I’m not..
You can see more than me. The port looks ok.
Finding out what common issues that device has may be useful.
For that device I'm not going to be much help other than the very basics.
Can you access the boot menu?
Use a known good power cable and charger; make sure they are good. Cables fail erratically and unpredictably.
Power it completely down and try letting it charge overnight.
ive been trying to sneak in but it shuts down if i try anything. plus i cant find one tear down video.. looks like i may be creating the first. ill sleep on it instead of jumping in half cocked.. ill give you update soon. thanks for your time.
tbh! i was gonna attempt to splice open old usb cord and bypass port using the wires directly to prongs? what you think

Get a new cable preferably OEM.
You start splicing and get it wrong or if the cable is bad at a different point... you're trying to troubleshoot it, not start new trouble
Sounded better in my head lol. but the first cord that stopped working wa replaced and did great till now. ive rounded up 4 others from storage. non seem to catch. im trying not to order a 2nd new battery and cord. even plugged into pc or laptop it doesnt recognize anything.
