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

Hello,
the bottom connector from my Himalaya is broken...
Does anybody knows if there is a sync-cabel for the back-side connector ?
Or a female plug (perhaps from a cable extension) would help me to solve the problem as well...
Thanks in advance!
I have exactly the same problem. Any advice on where to find that connector. I can't take to a authorized service, because there's none in Macedonia
Thanks
Hey guys, can anyone help please. At least if you can tell me where to find that connector on the internet, so I can change it.
I think it's the same connector as for the IPaq 3800 series, can anyone confirm that. Thanks

go to www.merconline.co.uk for xda2 parts very good for conector repairs
was you finding that cable. I am also searching it, pls tell from where i can get it. i also not sure is it for synch and to charge xda.
cant you charge just the battery on the xda dock?
and sync with bluetooth?
flyboy
but problem is this i cant flash through bluetooth
Exactly same?
I have a Himalaya(i-mate Pocket PC) with a broken USB , repalaced by only a charging port so that I can charge it but cannot flash it! Got the intact cradle though. Is there anyone who can repair my USB port so I can flash it again?
this happenend on My first Himalaya too,i´ve searched a lot through the Net
and couldn´t find any spare parts,what I want to say is...
theres a bigger Problem to find Spare Parts then to solder the Port to the board
(yeahyeah...which isn´t easy too..i know...)
But is there anyone who knows what is the backside connector? And is there cable for it?! It will be good to use it! Just to avoid, soldering and finding spare parts! Any info will be good! I have soldered mini usb 2 times and every time i do that after fall it came of! I'm sick of soldering!!!
MMMMMM That`s it!!!
Look all!!!
The backside connector isn`t for syncornizing an charging!!
It`s just for connecting the "High capacity" battery, you know the big battry with 2400 mAh.
All i want to say, you have to put a new connector to flash roms and charge the battery without take it off from your devices.
Hope i`ve help you with you problem!!!!

I knew that! But if u open a himalaya, and if u see below the back side connector there is a number of small dots, and every single of them are corespondenting for ones where the connector was soldered... So if anyone can find a corespodence for usb connection that will be good project... Just to avoid a use of old and crapy original connector, then u can use any connector u want! (for about 4 pins which is need for charge and usb sync) !!!!

Need help in fixing my samsung galaxy tab 2 7.0 charging/usb cable
Here's my situation,
1. I own original cable and soon tossed it away because the cable has got snapped wires and I find it difficult to solder to the pcb board.
2. I bought another cable, but again, it's having charging issues after 4 months or usage. I'm started to think that these type of cable is easily broken. So I wanted to fix the cable myself by open it up and resoldering the snapped wires in order to save money. The 2nd cable I bought has got no pcb board attached inside. Just pins and solderings.
For now, I just want to be able to charge using the original charger and be able to transfer data files using my pc. So I need help to someone to tell me which wire (color) is attached to which pins. 4 different colors, Black, Red, White and Green. Thanks before.
Here's the look of the 2nd cable when I open it up (removed the remaining snapped wires)
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
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.

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?
