Seems my USB port needs replacing, I first thought I may have had some lint or something inside there as it wouldn't charge but after checking with a flashlight one of the pins had bent completely.
The only thing I can find for the original desire is eBay ID 380759842289
Can anyone confirm if this is right, or where I could purchase one from the UK.
Are they hard to replace? Would it just be the case of removing the 2 lower t5 screws, taking the antenna out of way and then what? Are they soldered on or ribbon cable?
Cheers
I had a similar problem, my device couldn't connect via usb but it was able to charge, so my first thought was the same as yours (about the lint). I tried to clean it and I found something like a little wire which was out of its place.
I ordered a usb port (about 1.50 euros) for that model and I followed this guide on youtube to disassemble the device /watch?v=8sYB_AM_jHE
You have to dissolder the old one and then solder the new which is a little bit tricky. It Worked!
For the replacement parts you can search on ebay for htc desire g7 its the same or use google you will find a bunch of them.

Hello all.
I dropped my phone pretty hard the other day. I dropped it many times before so I didn't think there would be any damage besides that the battery popped out.
Once I got home and wanted to charge my Artemis I noticed that my USB connector is gone!
Well, I found myself a spare one on eBay, but as I looked at the connections on the circuit board of my Artemis I started to doubt the possibility to put another USB connector in there.
Some pins seem to be damaged real bad but not all of them, and then again I only want to be able to charge my phone and will not use the USB connector for syncing or using a headphone.
Can someone take a look at the picture I took and see if its still possible to attach a new USB connector to my Artemis and if it will at least be able to charge the battery?

Many thanks!
Repair of the USB mini port
Hey,
Could you send a picture with more sharpness, because i can't see it that well.
I already see that you have been soldering on top (close to your serial number).
Kind Regards

As long as you have got the correct connector then the way you do it is to remove the solder that is on the pads on the board and apply solder PASTE to the pins of the connector, then with a very COOL soldering iron gently touch the pins just long enough to flow the solder on.
evenin all, ill keep it short,
the mini usb connector on the mainboard has broken off, some of the solder p=ads are damaged, i need a replacement mainboard, can anyone help??
thanks in advanced

I suggest you try to post a Wanted ad in the Marketplace section. If anyone has one to offer, that's your best chance.
I´m sure I saw today someone selling Universal parts, not sure if motherboard...

You may use some thin cable (to use as jumper) in case the pads are broken and connect to nearest point.
Also you can buy a cheap card reader which has the same mini-usb connector. Desolder it and connect to the uni if your usb connector itself is broken.
the USB connector itself is sold on eBay for around $5, works very well on Uni or any device with the same connector. However, if the pads are damaged, it might be impossible to have one reattached.
I can offer Mda Pro's motherboard. Working good. Once fell down and display was damaged..
Message me if good for you.
yeah, some of the pads a fubar, thanks for the help people
Broken USB repair
I notice you live in the UK, I can fix the USB connector for you. Even if the pads are missing there are some test points on the board that you can solder fine wires to. I have done half a dozen of these repairs so far, this seems to be the most common problem with the Uni, even more so than borken screens. One of these days I'll have to do a 'how to' guide for it.
that would be nice, my soldering skills are up to the job, i just dont know how too, if you drop me a pm or something we can discuss it further
thanks
Guys, if you could jot down what you do and perhaps a piccy of the solder points, this would be great to put in the Wiki.
Hello people,
If its any help, my usb connection came off twice. both times it was resoldered back on with a standard soldering iron with the tip made to a point, and it still works OK. I found it easy to do, just needs a steady hand.

thats all well and good. but the copper pads that are used to solder the connector to the mainboard are fubar, so no amount of soldering will help
The micro-USB connector on my HTC Desire is damaged. Charging is not a problem. However, trying to connect it to a computer causes shows flaky behavior. I took it into the vendor who are estimating a charge of $140 to fix it.
I can solder/desolder the connector quite easily as I have SMT facilities at work.
I would like to source the connector first however.
Anyone know the part number or where I can source one from?
Hi
try to sample one from eg Molex.com
I think you have to pay for the shipping oid
http://www.molex.com/molex/products...pageTitle=Introduction&parentKey=usb_products
Good luck
Thanks.
Would be good to get a more definitive part. Dont want to desolder and realize I have the wrong part.
Has anyone seen the unsoldered PCB footprint for the device?
Is the connector a bottom or midmount?
Images taken from the HTC disassembly video (is on youtube)
But maybe there's just a cold solder joint and you don't have to replace the whole connector.
Thanks. Those pictures are neat. I took some of my own after opening up the back casing.
The damage is inside the connector (the cable wont stay connected). So not a dry solder joint problem.
I guess I could try and buy a few different connectors and try to see which fits.
Hi all.
Im hoping someone can help me out.
In the process of building the wireless charging hack for the htc desire and the prototype works fine.
However at the moment i have connected the induction coil circuit to a micro usb plug which then plugs into the desire. This is an ugly solution!
I would rather solder the induction coil circuit straight to the circuit board but am having trouble identifying where to connect to.
Has anyone looked into this and able to show me a +5v solder point on the board near the micro usb socket?
Appreciate the help.
Hi all.
Sat down with my multimeter and the desire in several pieces! Lol.
Finally found the contact points on the main board for the micro usb power.
Have now attached the induction coil to the phone main board and slipped the back cover back on.
Now I have a a desire with wireless charging using the palm touchstone but still retaining the ability to charge via the micro usb if needed!
I love the desire so much! is there nothing you cant do?

Good idea!
I spent ages trying to build a slim line micro-usb plug that could easily plug in and out if I needed to charge away from a touchstone but it was not very pretty and in my frustration I took apart the phone trying to find a points on the board instead! Initially I was planning on soldering to the micro usb +5v pin but that was way to hard so instead I searched for a contact on the pcb and eventually found one.
From the outside, the phone doesn't look any different from any other desire which I prefer.
Here are some pics. I can't take pics of the internals as I've put it all back together now and don't fancy the risk of breaking the tiny wires!
Attached some pics though as requested.
Nice project
Sent from my HTC Desire using XDA App
hi , i was thinking of doing this , when i got my phone apart i noticed two holes in the plastic that covers the microusb with two gold contact underneath, are these ground and 5+ i would check but my multi meter is bust
Hi,
this project is great and I also want to build this.
Could you please indicate the appropriate contacts which you used on one of these pictures:
http://blog.afkbio.de/index.php/uncategorized/anleitung-fur-displaytausch-bei-htc-desire-teil-3/
Did the copper coil together with the PCB (there is a PCB needed, I guess) easily fit into the HTC Desire casing? I tried to fit 5 sheets of paper there but couldn't close the case afterwards.
Do you have any more details? Will the Desire hold on the Touchstone or did you add magnets somewhere?
Hi.
Regarding the contacts, I used the 0v of the microusb socket.
The part of the pcb i soldered the +v to is not shown in those pics but if you look at pic 7, there is a square contact on the hidden side of the pcb connected to the microusb socket at the bottom of the phone. That is what i used.
I found that the case fits on fine and the phone is held on ok to the touchstone without any additional magnets but maybe that could be strengthened by thinning down the backcase a little.
i hope that makes sense. very hard to describe without pictures! i wish i had taken some when i did the mod!
I asked because I was afraid that I would need a "bigger" back cover as used by some extended batteries for the Desire. So you just extracted the coil from the Pal Pre backcover together with the board and put it on top of the regular Desire battery?

If you are talking about the ones to the left of the battery (the only ones i could find) thats +2.6V
Does it work through a case? Such as otterbox commuter?

I'll find out tonight, i'm going to destroy a powermatt cube and give this mod a shot.
Ok, so now I got my hands on a backplate and a touchstone and already disassembled the stuff.
The point is that I still need to know where to solder the 5V. How can I measure the various golden points? I have a multimeter, but where do I probe the black (mass) pin and where the red one (sample)???
I'm a little confused.
Now the pixel 2 xl support ended i am trying to root and install custom rom. But my device is not debugging...
When connected to pc only charging.. no usb options.
I can connect the usb drive and other peripherals
Usb debugging enabled in developer option.
Tried different cables.. different port.. different pc..
Is it usb c port problem or some software problem?
Any help advice!!!
Thanks in advance
I've got the same problem. Many have said they had success with different USB cables, but I've tried dozens without any luck.
I'm thinking hardware at this point, since I finally got the last OTA update and it made no difference.
I'll order the internal USB replacement part off ebay and see if it makes a difference.
I just replaced the internal USB assembly and nothing has changed. The old connector was definitely worn though.
I'll go back to trying more cables and ports. I ordered a cable that another poster claimed worked for them, but I had no luck with it.
For anyone wanting to replace their USB ass'y, here's what I learned from doing it. The service manual on ifixit is a good guide but leaves out a couple of important steps.
Heat is your friend. I used a clothes iron adjusted to 160F. The phone dissipates heat quickly so you may need to heat it several times. Place a towel over the screen and set the iron on it. I used guitar picks to pry up the screen and keep it separated while I heated the other sides.
The screen cable connection covers are hard to remove and you'll probably need a to use a metal spudger.
Heat the back of the phone to help remove the loudspeaker ass'y without damaging it, and again to remove the old cable ass'y.
The replacement ass'y I got had adhesive applied for the center of the cable, but not the adhesive foam pad under the antenna connector, so heat and scrape between the pad and phone body to remove it intact for reuse.
My old antenna connector partially came off in the white antenna connector and it was very hard to see what was wrong even under strong magnification.
You'll need a new screen adhesive sheet to reattach the screen securely.
Both parts came from a seller on ebay. Dougsgadgets was the only one that had both parts in stock. I think I paid $11 and they shipped quickly.
Good luck!
