please can someone provide me the circuit diagram of htc sensation 4g. actually, my phone's charging point (the micro USB Hub/port) was uprooted, so i took it the mechanic shop. the guy there told me that one of the point was badly damaged and could not soldered onto the motherboard. the D+ point was badly damaged. so now, when ever i connect my phone with PC, it does not recognize my phone. my Phones charges well but i can't transfer files from PC to phone because of the D+ not connected.
so, please share circuit diagram if you have. :crying:

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
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

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
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 guys i have a HTC one x at &t and as usual i connected my phone to the charger and the phone restarted and it didnt charge after wards ! and then i realised that my charger was burnt it also gave a fried smell ! and now my phone wont charge or conect to usb ! i think this is a hardware issue ! do u guys have any ideas to help me ! i would like to know if there are any jumpers or fuses in the charging ways ! please help me with this

im sure about it
:crying::crying:
thank you
I had the same thing happen on my old htc windows phone. That one had a removable battery i could pull out and charge. I'm pretty sure there's a tiny in line fuse on the usb port that has blown. If you're into micro soldering you could try replacing it. Otherwise the only option is pulling it apart and replacing the board with the usb port on it (most likely the motherboard). These tend to cost almost as much as a new phone, so unless you can get a second hand one from someone with a busted screen (or similar) i reckon you're out of luck.
Ps - there's no guarantee that some components on the board aren't damaged beyond the fuse, so motherboard replacement would be the best option.

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.
