Hi are there tutorials on repairing this at ease? When I plug in any USB HTC or Black Berry cable , on my phone it keeps showing disconnected then connected. Seems like the port is loose and I need a DIY on repairing this.
+1 i have the same problem, and a guide would be nice, i have search in 3 mounth now :/ and haven`t found a guide yet
same here, since yesterday :S
usb is very loose and even a very small movement unplugs it...
HD2 USB Ports are rubbish: loose/ Detached USB Ports
I've had two HD2s and both of them have ended up with detached USB ports. HTC's Customer Services invited me to return the HD2 and said that the repair would be carried out under warranty. I foolishly fell for their dirty trick and subsequently will have to pay £25 to have the broken phone returned to me or £215 to have it repaired.

I have had a UK SII since launch (originally on O2) but rooted and now using CM9.
Ive noticed recently that my charger needed to be wiggled a bit in the port for the phone to start charging.
Now it seems to have gotten worse and now i have to have the plug tilted in the usb port at a certain angle and apply pressure to it for it to start charging. Ive tested with 4 different leads. Connected to my laptop and phone keeps on flicking to usb debugging message so i am presuming the connections in the usb port are faulty.
Ive also cleaned a load of fluff out from it and its still the same.
The phone is just under a year old... so im hoping its covered for a 2 year cover like my old Sony Erricson phone.
Do you think they will repair this fault or make me pay due to excessive wear n tear?
I charge once a day over night, and dont use the port for much else apart from probably undre 20times connected to laptop.
Thanks
did you try the cable with something else than your phone? It looks like it's probably some broken part of the cable inside, but try anyway.
If it works fine with everything else it's your phone, if doesn't work with other things it's the cable and i'm not sure if they would replace it, because it could be your fault if it's the cable.

As I described above... i have tested the phone with 4 different usb cables/chargers.
I had my USB working properly till one day when all of a suddenly socket was broken. Don't know how it happend but USB socket was phisically damaged (plate with pins broken and pins hanging in the air without support). After puting the plug in it worked but only charging (I was suprised, that it worked at all). So I took it to nearest cell phone workshop and asked to replace micro USB socket in the phone. When they did it they informed me that it's charging but there is something wrong with data connection because phone is not recognised by any PC. Now it comes to my question. Phone, when connected to PC (several cables and PC's ) is displayed as "NOT RECOGNISED DEVICE" No matter if I connect it with SD card, without card, without battery, in working state or in fastboot. May it be USB brick which might be solved similar to HTC Desire solution ?
Sorry for typhos and grammar, English is not my native language.
I'd think that the physical damage has cut some contacts on the board.
You will have to live without USB connection

in most cases it's like reaching with left hand to right front jeans pocket...
hoped for some ideas like flash this instal that etc ooo well, we'll se when it gets bricked during some rom update or so, with no chance to recover due not working USB
Hi! My mother's S7 is not recognized by any PC right now. Before I order a new USB PCB I'd like to ask for some help here. The symptoms are:
- Charge and fast charge fully working
- Everything inside the phone is workin, not a single scratch
- When I plug in to any PC, no data mode transfer appears, neither under quick settings, just charging.
- Windows doesnt recognize anything when the phone plugged in, seen on device manager.
Did you install the Samsung USB drivers?
9 times out of 10 it is the USB port. This can be replaced by dismantling the phone and connection a new USB ribbon.
If you have tried this and ruled out the port, I had one where a dodgy charger had fried some components between the USB ribbon connector and the multiplexer IC. I had to replace components ZD8008, ZD8008, R8019 and R8020. These serve as input protection on the USB data lines.
Someone with microsoldering repair experience will be able to replace these for you. You be no more than 75 Euro. It does involve dismantling so may void warranty/water resistance.

I guessed so. Where can I find this components? Are they smds resistors, capacitors? I know microsoldering but does it deserve the effort? I mean, can I found a USB pcb replacement and just replace the whole piece?
Thank you very much!
EDIT: Like this one
EDIT2: I missunderstood your first line...I haven't already tried to replace the usb pcb. I think I'll try and if it doesn't work, well... I hope not -.-"
I draughted this reply before I saw your edit; sounds like you know what to do though: :good:
Sorry, it never occurred to me that you hadn't tried a new USB port flex yet. 9 times out of 10 it is that. Get one to try; fitting it is a pain because you have to separate the screen from the mid frame for the back/app button backlights but you can test it without removing the old one. They are very cheap and available on eBay etc.
If the new USB doesn't help, the fix is probably the microsolder repair I described above. Those components are in the main PCB so a USB daughterboard swap won't help.

Thanks!
So before my xz premium completely stopped charging my phone used to randomly stop charging and charged very slow I used quick charge 3.0 and certified usb c cable I had to put the usb type c cable in a certain position to get my phone charging but after a while it completely stopped charging I inspected the port it was fine no bent nor broken cleaned the port but it didn’t charge after sometime I started messing with the phone so I found a way to charge it when I put pressure on the bottom of the phone from front and rear of phone where usb port and flex cable is connected it starts charging but I have to put a lot of pressure to get it to charging I don’t know about hardware so I am here If someone can guide me ty.
Is the charge manager enabled?
In this case the manager try to think at which time you disconneythe the phone from charger and stopped after a while to continue in front of disconnect (or what he think at which time it is)
No the charge manager or (Battery Care) is not enabled but I opened the device myself because I thought it might be a loose connection of charging port's flex cable but it was connected to the motherboard fine but the situation was the same I pressed the flex cable where it connects to the motherboard and the phone started charging I think it's some sort of motherboard problem as it happened with some other xz premium users as well.
P.S:Replacing the charging port didn't fixed the problem.
Hello,
I had a similar problem.
At first it only carried in certain positions or pressing the region where the flat connection. After 1 months it stopped completely.
My problem was in the motherboard charge connector, I needed to buy a new connector to replace with solder. After 30 days, everything continues to function normally.

Thank you very much that's the answer I was looking for one more thing can you guide where to buy the connecter for the motherboard and can you tell me how did you manage to replace it.
Update I just got mine fixed the btb connecter for the charging port on the motherboard was loose it needed to be resoldered in case it is more damaged you should get a new btb connecter I'll put the link to buy from link: https://rounded.com/sony-board-connector-btb-socket-2x10pin-1306-0093.html
can u guide me how to do it?
If u know any trusted and skilled repair person just tell him what the problem is and make sure the repair person fix it the right way as described otherwise he might end up damaging ur phone.

Changing the port won't fix the issue it can only be resolved if u change the btb connector on the motherboard.
Anyone knowing how to do it?
Hi. Stripped phone down and removed old BtB connector. How do you solder the new part to the motherboard. Is it just the four corners you solder or do all x10 pins on each side need to be soldered?
Can somebody who has changed a BtB put a step by step guide if poss?

ok update i've been trying to repair it/solder it in a couple 3rd repair (because there's no sony xperia service center here in indonesia..) and they say they can't, then i wen't to this repair shop (this one looks not promising) then i got a message after 3 day they say they can't repair it, i was hopeless, i left my phone there.., and after 1 and a half month i think, i finally went to get my phone, and when i arrives to get my phone they charge me 15$, in my head i was thinking "why they charge me? they didn't even fix it"
then the repair man said "we fix it" i was shock they didn't even message me and said it was fixed (they have to) so i pay the 15$ and check the phone its completely normal it's charging the fast charge work, but.. they reinstalled everything (factory reset) kinda strange.. but it's find ok so that's it
To start off my USB port seems to be malfunctioning. I can charge but will always get the " charging slow" error. It will even charge via usb port on a pc but it will not recognize it as an external Storage unit. Ive changed the usb settings via developer settings. However i do not get a usb notification on my phone giving me the option to switch the function.
Is there a way to connect to a PC to use flashing tools/ADB in order to unlock my loader as well as flash and send commands to my phone. I can use LG AirDrive but i do not believe commands can be sent through that. Would greatly appreciate help since im lead to believe rooting has just hit for the Stylo 4.
If it is any importance. I am on the stylo 4 bought through best buy not attached to any carrier Q710ULM is my model number
Did you try another USB cable? Ive had several that broken inside and the same happened. Changing USB cable solved it
Ive tried several. It is definetly my USB port. I think dollar store chargers did it in. And now since its always slowly charging i think it won't do any data transfer maybe in fear of loss of data due to bad connection?

Yours is a micro USB port right? Most likely it's a faulty USB port. See if you can get a store to replace it
Yes. Well a Type C but android charger none the less. I guess id have to send to LG to honor the warranty. I didnt purchase ot from a carrier and also did not get aj insurance plan when i connected it to t mobile.
In other words you are saying im SOL for getting on ADB? Atleast until a one click root has a method for this device.
Just to test. Did you test in another computer to see if it is detects it?
My computer corrupted the adb connection due to faulty drivers. Reinstalling windows fixed it because in another computer that i have it was detected normally. It's just to test the whole scenario here. If it doesn't work RMA it to LG
Yes I tested it on a computer as well as multiple outlets. I finally just took the back off and took out the port. It had a lot of corrosion around it. Almost all teal colored. I blame those dollar store chargers. I have no other explanation behind why it happened. Either way there is luckily someone wihtin range selling a bunch of parts on offerup so I was able to pick uo a new port for 7 dollars off of him. When I removed the back I was pretty surprised to see how the "non-removable" batteries are packages in there. Just a bunch of layers wrapped up in thin plastic with some tape around it. haha
