connect s7 to pc from inside phone, port broken but - Samsung Galaxy S7 Questions and Answers

Hi, i've broken the usb port on my s7. It was charging but unrecognised on pc, port was full of gunk so tried cleaning it and think i've snapped a pin. It doesn't even charge now. I've taken the back off shattering it in the process thinking i could take out the charging port to have a better look not realizing it's attached to the screen. Also managed to snap one of the small brass connectors that the wifi antenna cable plugs into on the charging port flex. The phone will end up worthless if i try taking the screen off.
Is there a way of connecting to pc from the back end of the usb port with a stripped usb lead?
I got a new contract so was selling it to Game now a nightmare!
Any help appreciated
Thanks

Just use an FTP server / Client on phone/PC and connect wirelessly if WiFi still works
Or Bluetooth
Otherwise find the schematics for the port and see if you can work it out
Sounds more like a job for a repair shop though

(FIXED) Imate 9502 broken usb port

I have just bought an imate 9502 with a broken charger port (usb plug) inside someone has tried to fix it by linking the pins from the usb port to the pcb but have failed so bad that they have completely f*ct where the pins soilder to the pcb, i was hoping someone with a 9502 would be willing enough to open theres and take some macro photos of the usb port so that i can attempt to trace back where the tracks go and fix my phone.
Any help would be great thx.
P.s in the meantime does aybody know where i can get an external battery charger?
I ended up fixing it by removing the old usb plug and replacing it with a new one and than tracing back the power wires on the pcb than i bit of trial nd error but in the end found them, soildered some tiny copper wires back to the new plug and it now charges perfect
Only downside is that the usb still doesen't work so no sync with the pc at all
which usb plug did you need and where did you get it from?
it would help alot as i am also thinking of doing this to mine

USB port seems to have a bad connection... can i return for a free fix / replacement?

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.

[Q] MS Surface Cover Connector Pinout

I know this is probably more for Microsoft Surface Developer Section but seeing how I am still pretty new I don't have enough post to be able to post in that area.
I am mainly curious if anyone knows the pin outs for the Touch/Type Cover connector on the bottom of the tablet and if it uses standard USB or if it is some kind of special propitiatory type connection that would say connect the keyboard membrane to the keyboard controller that may be in the tablet? If it is just a standard USB connection I am thinking about cannibalizing a touch cover to see if I can create a home Grown Dock so to speak for the tablet that would have a USB hub for keyboard and mouse and a USB to Ethernet adapter that works with the tablet. The USB hub will draw power from a modified Power Cord for the tablet IF I can figure out that electrical later on to where it wont fry my tablet or other accessories but first I need to figure out the first part.
TLDR Does anyone know if the touch/type cover user a standard USB protocol and if so what is the pin layout for the connector on the tablet. If anyone can help that would be appreciated.
I just received a surface and they through in 2 type covers. said, "keep it" on a sticky note. I am now working on figuring out what the connectors are. I dont see the point of having 6 connectors, so I think that some may be ground or false. I will open up one of the keyboards to see what ships they are connecting to. i would think it has to be usb. I know that the 6th pin, that is 6th from the left pin, is 1.8v when grounded. I am guessing that the voltage goes up once the surface detects the attached keyboard. I will write back, let me know if you have figured anything else out. seems like we are hte only people on the internet who even care at this point. and microsoft is literally giving away surface computers.

any progress?
i already build a power wire, with a 5,5mm plug to connect it to my Intocircuit PC26000 for more juice on the go, and for a second charger.
you can see the pinouts of the power plug in the attatched pic.
let me know if you got any results for the cover connector so far - if its USB, i will implement my UMTS stick into a cover
Cheers!
just got pictures of the cover connector, see attatchment.
in fact all the 6 pins are connected. USB 2.0 would take 4 of them.
my guess is that one of them could be a switch, to turn the device & keyboard on and off.
any progress
Curious if anyone has made any progress on decoding the pinout, figuring out if it's usb or not?
i didn't do any further research - but it guess it's usb, or at least kind of... as it shows up as USB device in the device manager...

Judging by the connector and the fact that the covers are USB-based and can be used reversed, the pinout makes perfect sense. The likely possibility for the pinout is as follows:
Power Cover connector (Using pin labels in picture)
1/10 = Power cover +ve
2/9 = Power cover Ground
Touch/Type connector (Using pin labels in picture)
3 = +ve
4 = Ground
5/6 = Data +ve or -ve (reversible internally)
7/8 = Attachment direction detect
Pins on Touch/Type cover itself (Pinout from left [1] to right [6])
1/6 = +ve
2/5 = Ground
3/4 = Data +ve or -ve (reversible internally)
As to if the USB data pairs are swapped on the SP or the Cover, we cannot know without more information. Depending on the voltage supplied or the presence of unauthorised hardware detection (e.g. the ID chip in Apple earphones, I doubt it), custom USB devices should be fairly trivial (electrically).
I know this is an old thread but has anyone made any further progress on this? If not, I'm considering experimenting myself with a spare touch cover and a raspberry pi

Nope, im sorry, i didn't make further progress on this, exept what i already posted.. it is a USB connection, you can easily verify that yourself by looking at the Touch/type-cover in the device-manager...
I guess you can easily connect other USB devices if you build yourself an adapter..
but there could also be some kind of verification, if so then its most likely software based, if you hit a barrier, try reverseing the type-cover driver, you might find something there...
One additional info: the big outer nipples can be used to charge the device.
Peace
If I were to leverage the bottom grooves for charging, can you tell me which pin is which? +/-

Hi tfBullet,
When you say "the big outer nipples can be used to charge the devices" are you referring to these...
Power Cover connector (Using pin labels in picture)
1/10 = Power cover +ve
2/9 = Power cover Ground
Any new discovery?
Any new discovery?
will the power output still be live, if the data signals are not shorted? e.g: IOS devices
Can we just connect the keyboard via usb to a windows pc?
I don't think this is true USB, as there is no 5 volts anywhere on the connector, only 3.3 volts.. It may be USB, but needing to be level-shifted before you can use it. It may be potentially a way to get another USB port on the damn thing. Why did they think one USB port is enough? I have been trying to boot it from flash drive, but need keyboard as well, but the USB will not boot with a hub connected. Grrrrr.

Why not booting on a flash drive and use the usb for keyboard???
There's someone here who's made some progress...

i want to connect the keyboard itself to other devices
Hey guys
Good thread going on , i would like to see if any one of you ever thought about to use keyboard itself not the port , for some reasons I would like to use the keyboard on other devices (i mean kinda convert the pins to a USB port and use it on other pcs or what i really desire about is using it on Xbox) i want to see if any of you have any ideas or information about this , i mean is this even possible ? I've read the whole replies and most of them were about the port on surface and yeah its really cool , but i want to see if its possible to do , cause if its possible then it would be a lot easier than the port on the surface
Thanks

Well, take a look at the link Neakmenter posted, the guy there analyzed the communication, turns out it's no standard USB, it's proprietary.. Which means, there is no easy way of using this keyboard anywhere else than the surface... You would need some kind of microcontroller which connects to the keyboard, interprets it's signals, and relays them as Standart HID signals to a USB port..
The connector alone is a problem as well, you'd need to 3D print a connector or something like that, it's just not worth the effort i guess [emoji2371]

corrosion inside usb port

When looking into the USB port I noticed there is a slight build up of green gunk which probably came from environmental moisture (not sure).
Possibly related to this is that when connecting PC to phone, some USB cables won't work (and sometimes power surge), some only works in one orientation, some only works via the wall charger.
Before I send my phone in for repair, just wondering if anyone here has had a similar problem, and what you did to fix it. Any help and comments will be appreciated.
Hi, i had this corrosion too, what i did (maybe not so sure way) its cleaning the corrosion that was between the pins of the connector, so first i turned off the phone and then i removed it with a needle, be careful with the pins. When you finish use a brush to clean the port a little more and remove the dust it may have, you can put alcohol on the brush.
If your cables are not working you can try to press a bit both horizontal sides of the connector to ensure the pins are always touching. Thats what i did when my usb c cable started to connect and disconnect the phone randomly when i just moved it a little.

Hey. Welcome to the club mate. I screwed up my charging port after a trip in Thailand. Some underwater diving & swimming caused the green junk in my port.
I had the same issue such as yours after the trip, Charging was fine but connection through usb on a computer was screwed up.
What I did was, cleaned the charging port with alcohol (Nail polish remover), let it dry & sent it to a nearby Sony Service centre.
They replaced my mother board for free (In warranty). The best part was I had my bootloader unlocked & they gave me a new motherboard with a locked bootloader
Sony service center employees don't know **** about Bootloaders in my country, I'm from India btw.

Tf300t keyboard dock mod USB connection

Hi all,
I am trying to mod my old tf300t and keyboard dock into a dex dock for my note 9. Im not worried about the tablet portion as i can get a lcd controller for the panel. However ive been soldering and desoldering for the last 3 days. I am trying to leverage the docks kb controller and add a usb connection or modify the dock port into a usb.
I have looked at the various pinouts but cannot get the keyboard working.
I dont care about audio or sd card or the extra usb port.
Any help or pointers would be great.
Here is a mockup of the pinouts i have soldered based on the pinouts i found
Ive been trying to test it on an old s7edge incase i wire something wrong. It detects a regular keyboard but when i try this nothing...if i use the wall charger i see that the dock is charging but still nothing at the dock connector. Ive been trying with a usb 2.0 cable. Connected to the d+ d- vcc ( all 3) and multiple grounds and i pinned the sense pin to ground as well.
I have also tried to open the charge cable and solder the usb to the data pins on that both with and without ground. And use a 5v plug and the original asus plug.
The dock port is basically garbage at this point so if i plan to use that i need to use the 2 20 wire connectors and map the individual wires .
I have managed to get the s7edge to detect that something is connected. However i then resoldered the pins to try more as it wasnt working. So i need to go back to the beginning to try again. I believe my issue was due to the otg aspect of the usb. Im using an adapter for the phone but i also tried to wire the connector the same way. Ill take some pictures of it later if i can get it working
So not sure if anyone is following this thread but i have made progress.
I have totally butchered the original 40 pin connector and now am tapping into the 40 individual wires that connect the main board to the connector pcb. I can get my s7edge to detect that the usb connector is attached but it keeps telling me that a high power usb device is attached and that it needs an external power source.... so today i busted out the multimeter and i believe i connected one of the usb host vcc connections to the other vcc connections so i separated this. I also believe that the s7edge has some usbotg voltage issues so im going to test it with an old macbook pro with windows to see what it picks it up as. When i get some more time i will try to trace the other wires there might be something else needed
Maybe
Nice job, I'm not particularly knowlegdable in electronics but I remember there is a battery portion in the dock? Maybe it causes some error during otg?
