Hi,
My usb port on my xperia broke previously and i had i repaired but now its broken again. Would it be possible to re solder a brand new usb port as the the guy at the phone shop says he might not be able to re solder it next time.
Any response is greatly appreciated.
HI,
It is possible almost everytime but, MIGHT take very long time to resolder, if copper pads are took off the PCB. Therefore, it mustbe soldered back on other pins.
Anyway, it is possible.
.
Thanks for your replay.
I know that the outer big pins are the ones for charging but are they inner small pins for data connectivity?

Yes - outer are GND (-) and VCC (+) - inner D+ and D- (DATA). One pin is unused. Here is the pinout:

Thank you for your reply.
This was very useful and now i can out smart the phone guy when he says in can only charge meaning he hasn't soldered the inner one on.
So hit Thanks pls
If that guy was the technician, ha propably knew that. But there maid be a reason, why he didn`t soldered them - maybe it wasn`t possible due to damaged PCB...
Just guessing
..
I did get my xperia fixed once but it only charged and when ever i connected it to my computer it only charge and did not connect to the computer. Is there a solution for that?
So your phone was repaired after damage? Am I right, that it wasn`t repaired by yourselve?
So, you could find out if data pins are soldered - download Terminal emulator
here.
Then open it and connect your phone with PC via USB cable. Once phone is connected on both sides, type "dmesg" and see output. There must be something like this:
<6>[23469.853208] *********** Charger Type: HOST PC
<6>[23469.853384] Charger Type: STD DOWNSTREAM PORT
<6>[23470.708433] msm_chg_usb_charger_connected
If charger type is DEDICATED CHARGER, data pins are not connected or not solderd properly.
Thanks a lot.
It`s OK - you're welcome
I've got a phone with a broken USB too. I've got a new USB port and was looking for some information on how to do the soldering. Thanks.

Hi, if you don`t have any experience with soldering (of anything) - Don`t do it, you may damage your phone permanently.

Has anyone here tried one of these cheap ones from Hong Kong?
They are cheaper than the nearest option, and come with the right plug too.
It can't be expensive cause it consist only from ac/dc adaptor, usb plug and battery charger. I think it's right device.

I'm sure it is, I just wondered if it's likely to be good quality.
Tell you what, I'll order one and report back here once I've used it.
As promised, I bought it and here's the verdict.
Basically, it does what it says on the tin. There was a slight problem with the usb connection, but that was always the case with this computer unless I use a particular lead. Using the lead that came with it, it wouldn't connect. but using the one I normally use it works fine.

Having used cradles before, this one is slightly more awkward to connect but that's because it uses the usb connector. Previous ones have been spring loaded contacts and the pda would just drop into the cradle. This one requires a little force, but nothing major.
I've yet to determine if the charger works as fast as the original one.
All in all, well worth the money.

Hmm, seems I spoke too soon. The PDA won't charge unless the computer is on.
The 5V adaptor plugs into the back of the stand, as does the usb lead. Either of these will bring on the blue LED on the base, but the usb lead lights it brighter. I suspect there may be some problem with the 5V from the adaptor.
I shall investigate and report back (if anyone's reading this...)
charging with PC off
Hi -- I think I've got the same charger as you, and mine seems to charge fine with the computer powered off. . .
Alan
Having investigated further, it appears that the +5V from the charger and the +5V from the USB are linked directly. This means that with either one connected singly, it's fine, with both connected and the PC on, it's also fine.
But, with the PC off the +5V from the charger is fed back through the USB lead into the PC which pulls down the voltage somewhat.
I discovered this when I turned off the PC and noticed some front panel lights glowing slightly. I unplugged the cradle and they went off, and the blue LED on the charger became brighter.
dock
hi,
i've got the same "hong kong" dock as xmastree.
I think this is a good dock, simple and cheap.
regards.
I know the dock will have 2 full size USB ports. But honestly I'd rather just have a little adapter that I can plug into it.

The Samsung Galaxy Tab 10.1 will have one so hopefully Asus or another brand will produce one to compete!
Would something like this do the trick?

Oh gawd! With this delay and endlessly searching for release times, I forgot about that
How about a dual Female A USB adaptor
Amazon: USB 2.0 Adapter Female A- Female A
...plugged to the cable adaptor that comes in the box?
The cable also has data connectivity for data transfer, it probably should do the trick.
I believe the HongKong electronic shops would come to the rescue. They are known to produce many useless converter before. I don't see why not this time. Probably straight from ASUS connector to USB.
I posted something on on Asus' Campus Life. Please his reply to it and respond requesting this accessory! Look for username Dean.

I hope they make something similar to the hinge on the keyboard dock, so it can actually latch on and has the two usb's and the SD slot, it would also make a nice grip when using the tf vertically. From the pics, what they have so far looks like it's going to stick out a lot and with something that big there is definitely more of a chance it will get knocked out and possibly damage the port.
Dont we have to have usb host support first for the transformer and dont we have to wait for honeycomb 3.1 for that?

Doesn't look so. And some people reported that Female A - Female A adaptors work for some devices (those that have their own power source probably) - there is a thread about it somewhere in this forum. I tried it but my pendrives nor mouse didn't work (there is probably no power line in the USB cable that is used for charging and connecting to computer).

Any ideas on release date to the USB adapter ? Pete
Hello, the other day i connect my n9770 to the computer, and this turn of and not restarted. It say: "Error! Please plug out charger!"
I've opened the mobil because had to change the screen and I have looked if he had any bad soldering, but everything seems ok.
The Flash tools not recognize the mobil.

Same Problem showing in my phone..how to solved ur problem....pls. Reply me as soon as possible
This means 1 of 2 things.
A. The phone is liquid damaged, and the solder around the charging port is corroded.
or
B. The charging port is coming a little loose, or some of the pads have cracked a bit.
To fix A. Clean really well with 91% Rubbing Alcohol and toothbrush, and take a little heating gun from a rework station, temp set at 349C for me, and move the gun back and forth over the port slowly and steadily, until you notice the solder melt, lift the gun away and turn off, let the solder re-set itself. Try to charge it then.
To fix B. try A's solution first. If it doesn't work, buy the charging port off the internet for your phone, heat up the solder, and gently pull the charging port upward off the board, insuring the pads are staying on the board. Heat the solder back up, and place the new one in the exact spot, in the exact direction. Let it set, cool down for 10+ minutes, and try it.
For liquid damaged phones I clean the board really well with a mixture of Alcohol and scrubbing bubbles foam on the entire board. Taking the board out of the phone of course.
Your Phone Is liquid damaged
you might change the charging port of your device this will solve your problem
hi, my phone (infinix zero2)fell down and went off, i thought the battery was low and plugged it it now brought out erro pls plug out your charger, what should i do?
Error please plug out charger solution
watch it - youtu.be/zxMfXKLte2o
Warning, your warrantee is now void. I take no responsibility for damaged devices doing this mod, nor any issues that may arise in the future from doing this
Just felt like posting this little mod I did to a Nabi 2. After re soldering tge wires on the oe charge cable it finally couldnt be fixed anymore. It didnt take long for me to get frustrated with the flimsy, thin charge...thing, and rip it open to see what could be done.
After a little poking and prodding I found the simplest solution.
It seems the 5v pin on the usb port is electrically separate from the charge circuit, but they all share a common ground. Soldering directly to the usb port was all but impossible because of how the port is designed, and my soldering iron isnt that tiny, but I found a resistor tied to the 5v pin.
I soldered a wire to the resistor since it had a decent surface area to get a solid solder joint, then soldered the wire to the positive pin on the charge port. The result? Micro usb charging.
I have found a bit of a glitch however. Plugging the device into a pc does properly kick it into usb storage mode, but because of the low amperage, it begins to cycle the charge system between charging an not (as if contantly plugging and unplugging the device) the same happens if you use a charger rated lower than 1amp or a bad cable.
Besides that it seems to be doing fine

Thanks. Not sure why I didn't think of this years ago. Been searching for the original cable to try and make some use of the tablet and decided to see if it was possible to charge via usb. Couldn't have been easier to modify and it works perfectly.
Any way to disable USB charging?
dafuk?? .....
Im guessing you use like an mhl cable or something in that nature where you need the data connectivity but not the power from the cable?
Then well strip the cable and remove the power lines. RED and BLACK and solder together.
Or manufacture a modul. Lets say you buy a usb extension cord. Break that cable and remove the power cable. Plug in the extension cord between the micro usb cable and mhl or whatever device you're using.
Or I dunno... I think you need to explain y u ask this question..

Yes, something like that (DAC/AMP)

Doing that won't break otg connectivity, since the 5th pin is also used for sync..?

Then I believe it won't be functioning as otg anymore.
Overall - that's why I wanted on/off hack to turn this on demand only (night charging...).
Yes you are right. Looking at this photo the ground is being actively used for turning regular cable into OTG with pin 4 to pin 5

What you could try and the only thing you really can do here. Is to cut the vcc (red) cable and solder on a switch. Perhaps buy a box to feed the cable through. Drill a hole for the switch. Solder on the vcc cable from the usb cable.
A switch like this, or a screw on model.
http://www.ebay.com/itm/5Pcs-Black-...908?pt=LH_DefaultDomain_0&hash=item27fe925acc
A box
http://www.ebay.com/itm/Junction-Ad...961?pt=LH_DefaultDomain_0&hash=item33a3085b49
Or you could buy a ready made kit
http://www.ebay.com/itm/AC-380V-10A...0&pid=100005&rk=1&rkt=6&sd=330789747574&rt=nc
Flip the switch before u go to bed and turn it off when its done.
From looking at the first picture in theory cutting the vcc cable and turning it from nc to no would just stop the device from charging. But I am not sure. Because there is as you say data actively being fed for the OTG interface.
The two things that can happen is
1: The device stops charging
2: The device loses OTG connection and stops charging
So yeah.. If you have some spare time to take in. Try it and see what happens.
