how to find out if usb port is defect? - Galaxy S II Q&A, Help & Troubleshooting

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.

But does it charge when connected to PC by USB?

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.

There could be Two Reasons Your Device's Micro USB Port is Broken Something.

Nope. Kies doesn't respond.
fxrb, thanks a bunch for the explanation!
I got the flex board off ebay already. There's a nice guide on youtube.
Ah, ok - you were quicker.

blondbread said:

fxrb, thanks a bunch for the explanation! I will look into this flex board alternative. Is there anywhere further information? I got the phone pretty cheap so I'm willing to give it a try.

Further information about what exactly?
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] USB Cable?

My USB cable for my x10i seems to have developed a loose connection so now my pc wont recognise its been plugged in and the cable has to be jiggled about to get it to charge.
Anyone know the type of cable i need? or a cheap online place to get one?
All you need is a micro USB cable. You can find them pretty much in any phone or computer store. Or try Amazon.
It doesn't have to be branded. I bought an inexpensive generic one and it works just fine.
which EXACT type is it????

OEM USB Cable

Anyone have any idea where to get the SE OEM USB cable?
Ebay?

Do you have the model number?
I'll check when I get back home.

I'm curious as well. I thought that something was wrong with my phones USB port as I have to wiggle it around before it connects (very loose connection). tried plugging my phone in with other cables (blackberry and arc) and it stayed connected fine. Friend of mine plugged her phone in using my cable and it did the same thing as it does with mine. It's reassuring to know it's not the phone as that would be expensive to fix, the cable on the other hand is cheaper If you find one let me know.
Sorry, I seem to have lost the little tag on the USB cable that shows the model number.
Hi,
I have "datacable by OTB" which also charges my nokia for a few bugs from EBay. Every cable with mini- (micro-?) usb should do.
Ralf
Asked my friend, Model Number is EC600L
Ye any micro USB cable will work.
Some people prefer OEM
It's a feature! micro USB was intentionally designed so that the cable will wear out rather than the jack.
On another thread it was suggested that biting on the end of the cable tightens the cable allowing it to connect. I seem to have revitalized my old original cable though I substituted a pair of needle nose pliers for my teeth.

If you really want a model number I recently bought an OEM cable for a spare for work etc its labelled CA-101
As above though its a standard micro usb cable ...
(used this cable recently to flash and then reflash my x10i after killing my phone with various patching and the cable works great lol!)
Note I also use a Nokia mains charger for my spare work charger as that's all the guy had on his stall and it works just fine
I have the Nokia CA-101. ill check the OEM one when I get home. but I like the Nokia OEM one. it's longer :3

I am using an BB micro-USB cable as my alternative cable which cost me MYR10 around 3USD. Bought from a local Computer shop. Mobile phone shop sell at higher price.
Notice that the stock cable charge my phone bat. will reach @ 40'c while the BB micro-USB cable will above 40'c. Maybe due to the stock cable having 'resistor' locate near the both end of the cable meanwhile the BB micro-USB cable don't have.

[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..

[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

It actually is microUSB. I lost my OEM cable (which is slightly different, i think they added a couple pins to enable fast charging) but I use a motorola cable and it works fine for charging. it just takes a ridiculously long time and it doesnt charge while you're using it. unless you have a B&N store around you (which i'm going to assume you don't) you can't really get a new cable. maybe online but i wouldn't do it, chinese cables are cheap, bad, and potentially dangerous

yeah the B&N store or its products are not available here in local markets or online stores.
I am gonna try charge it on the regular micro usb cable. thanks for your suggestions.

hi, it worked well. I switched the tablet off, put it plugged in all night to my laptop, and by morning at 9 it was fully charged.
Thanks for your suggestion. :good::good::fingers-crossed:

Yes the B&N cables are special, the pins are longer and more of them to tell the nook to fast charge. But as you found out, any micro USB cable can work, just slow slow charge it. And you can't use the device and charge at the same time as you will be using more energy than is being supplied. Oh another help is to turn off wifi when charging from USB, having that on will have the device charge slower as the the radio will be accessed occasionally.
I did find this http://www.amazon.com/dp/B00FMMPDT4/ref=twister_B00FMMOSYU the connector looks longer than standard USB so perhaps it would work. I can't say for certain of course. I also saw used Nook Tablet power adapater/cable sets on amazon as well (original OEM). And a final suggestion would be to get one from ebay. I have seen a few there as well.
I am surprised B&N won't ship the cable at all. Seems like they would want to sell/move them. I was looking at them the other day and you can see how the V2 is from the photo. The connector on the nook side is not long and easy to snap off/apply stress to like the original. http://www.barnesandnoble.com/p/nook-color-new-cable/27359237?ean=9780594459453
If anyone ever gets the KS cable, please post so we know it works for sure. It looks like it will, and I may even contact them to see. I think the biggest problem with the original nook color/tablet cables was the nook connector was too long/straight and easy for people to break (that and the connector wasn't reinforced like it should have been).
@skepticmisfit
I see some sellers from china who can ship the cable to my local address. I'll see if I can get a good one.
Also, keeping the cable connected to the laptop's USB 3.0 port is useful. :good::good::good:

No. It seems i don't need a nook's stupid cable at all. The tablet gets charged on usb 2.0 port too. I am using the CM11 nightilies ROM and gapps minimal, that is efficient in terms of battery usage.

Does it fast charge? I thought the NT would only fast charge if you use the B&N cable? Or is the fast charging lock to their cable only work with the stock ROM?

You don't really need a replacement Nook charger, any 5V 2A USB wall-charger plug and a regular micro-USB cable would do although it would take a bit longer to charge.
While Digi is right, there are official Nook cables and chargers (refurbished) on ebay at the moment. You can still get the cables from Barnes and Noble but I don't know if they will ship to India or not. I would try searching for "nook tablet" on ebay.
Also if you are going the generic charger/cable route, be sure to have the screen and wifi off while charging. If you have the screen on, it will discharge faster than you can charge it.
One final note, even if you are going to get a official charger (which I would recommend as it is so much faster) it would be wise to plug it in to a generic cable/charger combo for now. It is NEVER good to leave the Nook laying around with a dead battery. It will kill the battery in short order. And it is harder to get a Nook Tablet going again with a generic charger if the battery gets too low (shuts down on you).
