defy usb port problems - Defy Q&A, Help & Troubleshooting

I'm looking for advice. the USB port on my defy seems loose and only charges if plugged in a certain way. ive physically opened my phone and inspected everything but i cant visually notice anything, and the brace holding the port down is solid. has anyone had and fixed a problem like this? if so could you give me some tips on what to do or where to further look to repair the port. thank you in advance

i have the same problem and has been living with it for the last 1 yr or so! don't know if it was the usb port or the cable's fault but don't have another cable to try
one word of advise though. don't try flashing any sbf or you might end in trouble with an incomplete flash......

thanks for the link. keeping it just incase i decided to do it too. i've already bought a couple of cheap/fake batteries and a desktop charger.
46c each!!!??? that's cheap enough, except the postage/freight is going to be much more
good luck and let us know the outcome.

Just in case either of you were wondering, I have not received the USB ports just yet. I will be posting a successful repair one way or another!

crashed and burned. destroyed the PCB where the USB ports are soldered... theyre just too small to be re-soldered by human hands. only way to charge my defy at this point is by macgyver some cut USB cables onto the battery terminals..

i'm sorry to hear that! you could alway buy a second battery and a desktop charger to get around your problem like what i did. they both can be bought from ebay for a few dollars each, like:

Phone struggling to charge.

Hello everybody. Recently, I had my phone go under a repair which involved opening up the entire phone just to replaces the mini usb port, which was detached from the phone and was trapped inside, losing its ability to charge.
Now, another problem has arisen. The phone has problems charging with wires compatible with its port. When I connect to it to charge via usb, it was plug-n-go, all good. For some unknown reason, it suddenly came under the issue that I need to shift the usb up,down, left, right, and slightly bend it the inside. Now, the original charger doesn't work because it broke, leaving the usb charger as the only option. I can't understand why my HTC Wizard is having this problem,and it's very frustrating. I paid sixty dollars for the repair on the USB, and it seems it hasn't done anything except reattatch it. Any suggestions?
Hey Infinity M,
By your description, it looks like the soldering is a bit loose, thus you have to shift the USB.
Have you tried with different chargers and cables?
If you wish (at your own risk), get a thin screwdriver or something like one, then apply a small force to all directions at the border of the Wizard's USB. Watch if it moves with any pressure, as that will indicate a loose solder.
Good luck, man!

Thank you for your sufficient reply. I have not tried a different cable, and I have checked the Wizard's USB. I'll have to try another cable to check if it works. Do you know where I can buy a charger for a cheap price. Thanks!
Edit: Heh, I realized you're the same person making that HTC Obsidian Case, I'd love to pay you for it lol.

That's a hard one. I would send you straight away to eBay, lol, but I guess you can take a look at some local stores near you. It doesn't need necessarily to be a Wizard's charger. In fact, any charger for a HTC device that uses the same battery will do (the Tytn's I guess). Or you can check the charger label and see if it meets these requirements:
INPUT: 100-240V~0.2A
OUTPUT: 5V, 1A (this one being the most important of all)

[Q] Broken USB Port

Soo... I think the USB port on my T-Mobile HD2 is gone. I can feel it jiggle around when I plug in a USB cable... that and nothing happens when I do. No charge, no USB notification, nothing. Not even plugged directly into the power adapter.
My question is whether anyone knows any way to repair the phone for cheap? I've taken the phone to several cell phone repair shops, but no one can do anything without sending it off to HTC. If they do that, then HTC will charge me a crapload because the custom software on the phone somehow must've caused a hardware problem. Because the USB port is broken, I can't flash back to factory, soooo... there's nothing I can do there either.
Any help or advice would be appreciated. Thanks!
My first and only suggestion is to look for the not working phone body of HTC HD2 at ebay.com or similar. If You have some manual skills it wouldn't be so hard to replace it by Yourself. Of cause it is almost open heart surgery but it is possible to do by DIY.
If something like this would happen to me I would do so. You can look for only micro USB port to take it away from other non-working device like old camera or mp3 player or other phone.
Why they decide to use mcroUSB instead much solid miniUSB i don' know.
You can also look for micro USB connector
here
You can put a stock winmo rom (LEOIMG.nbh) on the root of your sd card and boot up into bootloader by holding the volume-down button while booting. Then the bootloader will detect the .nbh and ask you to press a certain button to install it. Then you can send the phone off to htc, it will be completely stock.

Wish I could, but apparently the cell phone repair shop that tried to fix my phone decided to tell HTC about my custom ROM though he told me he would be doing the repairs (only reason I left the custom ROM on there). But they actually decided to ship it to HTC. HTC decided to record the serial number so I can't send back to them anyways. =/
About the DIY repair. Would it just be a case of re-soldering the USB port back on the phone? Or is it something more technical? I'm asking because the cell phone repair shop I tried out said that they needed to replace that entire board. AFAIK, that board is the mainboard. Doing so would require buying another HD2 body, but I'm afraid that would cost far too much as I am a college student with ridiculous school fees and a very low income.
1: aww dude that sucks, they got you by the serial #
2. I have a broken micro-usb too, saw the disassembly vids, and it looks to me that the m-usb port is attached to the mainboard, and you have to consider too that if you try this as a DIY project, people have had wifi coax become damaged, lcd/digitizer damage, who knows what else from 'professional' repairs, let alone doing it yourself.
2 options, get a card reader and an external hd2 battery charger (and preferably a spare battery), or have the micro-usb port fixed by someone else or by your self.
The external charger and spare battery is cheaper by far, i paid only like $8 for each, and it's surprisingly reliable and practical.
Hope i helped

i would totally call out on that shop and demand they fix it, since they ruined your warranty by sending it off to htc without your consent..
also, search on ebay, theres a cellshop in texas that repairs the port for $50, you mail it to them takes about a day and they mail it right back.
That sucks...I feel like the micro USB on my hd2 is about 2 die...if the phone moves at all connection and charge is lost. why oh why did these bums pick micro USB there's got 2 b a reason
To me is a serious design flaw...I mean its only a matter of time b4 the micro USB will fail on each and every hd2 regardless of how much u baby it device (which most of do)...after a certain number of charges the port goes bust
IMO the micro usbs put 2 much pressure on the port itself it's simply not big enough/solid enough of a connection to support the weight of the wire itself and over time gravity loosens and destroys ur port until u can't even.charge
Sent from my HTC HD2 using XDA App
I agree, the micro-usb is crap. Had my hd2 for like 2 weeks and i broke it by the charge cord getting caught on my foot, sending the phone flying. Luckily, i found that i could get a connection to my comp by holding the cable 'just right', flashed magldr and cwr, and just charge my batteries on the external charger now. I was stuck on the winmo 'test' rom for like 6 months lol.

dude same thing happened to me yesterday i was charging my phone and i got up to do something. And the cord caught on my foot and the phone went flying also. and when i tried to charge its like if you move the phone even the slightest it looses connection. But i found a fix that worked for me. im using my external hardrive cord to charge. the connection is a little thicker and fits in there perfectly so now i can move it and it stays connected... Only downside to me is the cord is really short

Yeah, I railed at him for a good 10min in the shop with customers looking (hope I drove away some of his business...). He said that he couldn't fix my phone because I had *illegal software* on it... really? I doubt that a software problem caused the microUSB port to just break off the mainboard.
I've also looked at the disassembly video, and it doesn't seem impossible, but the cost of a micro-usb port is around $35 from what I gather. I think it would take some soldering to replace it, but I have neither a solder nor the experience to attempt it the first time on a $400 device.
I guess I'm stuck with the microSD adapter and external charger for now. ~sigh~ Maybe I'll try another internet-based cell repair shop. Anyone know anything about cellulardr.com? It's based just a couple miles from where I live and they have the part in-stock with a 50% discount that brings the price for repair down to $35 + $35 for parts which is a little high... but if it gets the job done...
I'm a [fraught] example of the result of thinking the usb would somehow last if I was just gentle. Who was I kidding, it was shot to pieces.... I've dropped £100 fixing the phone's screen which resulted in the volume buttons and vibrator dying (I argued till I was blue in the face- before I demanded they reglued the screen back on, a day after it had been 'fixed')... Damn crappy little repair shops, no leg to stand on.
And now I can't charge it.
Waited 2 days for a wall charger (and believe me that was hard as it's my work phone) to find that nomatter how long it's charged for it's dropping from 80% to dead in about an hour no activity.
I wouldn't mind so much but to have finally found a rom I liked, right through from WM to SD android versions to now Cotullas Nand, I'm reluctant to give it up, even though it's more than likely on it's last legs.

If they made these things more reliable, they'd never have a means to convince you to buy another device .
well a usb port repair is totally possible with just an soldering iron, but you will need a fine tip for that and some flue that does not require cleaning. if any of the contact pad came off you better know where they go or find a way to trace where it goes. if they are broken and you find where they are connected you can use a copper wire taken out from copper brace to bridge them. lastly a broken usb port from the motherboard will never be secure again, so you have to put some padding under it so it will not be moved again; otherwise it will break and may take some contact pad with it in which makes it harder to repair again.
I fixed one of these before with only 1 broken pad that I can trace. so it is definitely possible to be done, but it will be very hard if this is your first time repairing phone. it is possible to rip the volume flex cable like I did. It took me 4 hours to solder flex by rewiring copper wires.
By the way hd2 usb port is only 7$ from eBay.
P.S the good thing about fixing phone is that, I got it from eBay, fix up, and working at $120 XD
Phone going crash
I don't know what happen recently with my phone. It just starting crashing on normal activities. I thought it was probably just the rom, but I flashed HyperDroid GBX v12, clk version and damn....i can't even get pass the boot animation. After a while I did...and then I connected my USB to my computer. Within seconds, phone crashed. I need help. I've task29 this kid like 4 times and then installed clk again.
Sometimes it is just the usb cable quality causing a bad connection... I had this Chinese micro usb data cable and it would only work at a "just right" angle, until I went to Radioshack to buy a 27 $ gold plated usb cable lol
Now everything works good and saved me from having to replace the microusb port on the phone.
Woow I thought I was the only one! I feel all your pains man..
First things first, those of you whose USB is still working, get clockwork mod set up before the USB dies.. at least with a card reader you could still flash thru zips.. I got an external charger and an extra battery as well, now I feel like my hd2 was sorta reborn! Haha..
Dunno bout you guys but I'm starting to feel that our beloved hd2 is slowly being abandoned really sad thing.. and I blame the hardware problems for this trend..

Nah, it's just nearing the end of its life cycle. There are better phones coming out now with faster processors and more resources to run bigger software and flashier graphics.
The HD2 has actually stayed on the top of the hill for a surprisingly long time, and in some ways still is.
The biggest difference with the HD2 compared to other phased-out smartphones, I think, is that the HD2 is still very useable even though it is well beyond its originally intended amount of time in the limelight.
I notice this whenever I dig out one of my old devices that I haven't used in a long time, like my Kaiser or Rhodium. They are so slow and basic that they're almost unuseable, where the HD2 is fast, smooth, and seems modern still.
But the mUSB port on these things is ****. Mine's been half-busted for almost a year. I have a wall charger and extra battery, and if I hold the cable just right, I can usually get a connection to the computer, but it's just easier to pop my sd card in one of my old devices to connect to pc and transfer files. The mini-USB ports never gave me near as much trouble as the micro ones, I wish they'd have never switched.

Hi all,
Just thought I'd let you know how I fixed my HD2's loose / non-functioning microUSB port.
I've had similar problems for the last 6 months or so - dodgy microUSB connection resulting in massive amount of fiddling in terms of getting the cable just right, then pretty much completely screwed!
I took receipt of a HTC Sensation a few weeks ago, so decided to spend a little while opening up my now redundant HD2. Dissasembly is pretty easy & self-explanitory, but the leaked videos showing you how to do it is pretty useful. I'm no whizz at these things, but even I managed to do it (mostly) with just a kitchen knife (forgot where I'd put my small screwdrivers, which I eventually found, but everything seemed more dangerous & exciting with the knife).
ANYWAY, I've managed to secure a completely loose microUSB port which means perfect charging & USB connection again. It was incredibly loose & just fell out when I separated the mainboard from the chassis, but I put a bit of rubber I found under it (soldering iron is for pros... I'm winging it here!) & secured the mainboard tightly with screws.
I mean, there's probably a better way to do it, but I couldn't be arsed using any more ingenuity than required... it's a Bank Holiday after all, and the solution seems to have worked pretty damn well.
Cheers,
Dan.
Hi, I can only charge my HTC HD2 phone using the USB port, but I cannot use the usb port for activeSync and USB function (data transfering). I wonder if the USB posrt is dead already?? Why the phone still can be charged via the USB port? Can anyone tell me how to fix this?
Thanks in advance.

Repair Broken USB port

I just bought one of these from Kijiji. Tested everything out, handed her the money, only to find out it is a pain in the ass to charge. The port feels loose and the corn has to be in perfectly to get it to charge. I'm mid contract and totaled my other phone, BlackBerry Priv, so I thought I'd try and save some money. I thought wrong.
Is there anyway to repair the port? The rest of the phone looks almost new and I'm impressed how much faster this phone seems than my Priv with the same apps on it.

Not yet, that's going to be my last option. I can't do it myself, but have a friend that says they can. The really strange part is the cord it came with seems to work ok, but every other cord won't. It isn't the original one either. It's a 10' generic cord, but it seems to work. It's just a pain to keep carrying my cord around everywhere so I can charge my phone.

If you have a cable that works good, then it's a good sign!. Do you feel it a bit "harder" to put in place?. It might be that the two small "legs" below the connector protrude a bit more so they push more against the female connector inside the phone, or maybe the golden pins inside are of better quality. You could try bending them carefully with a needle, always on the cable. Don't touch the phone!

The working cable definitely feels tighter than the others. I've had a look at the pins on the phone and the other cables with a hand lens. The phone definitely has some damage to it, but the pins look to be intact. My cables, for the most part, are almost new and in good shape, but the 'legs' don't seem to stick out as far. I guess for now, I'm going to stick to using the one cable, I may try to buy the same name brand as a second and see if that works.
Thanks for the help.
You are welcome!. Good luck!

Replace internal Charger Port Cable?

This phone did, intermittently, work. But it also behaved as though there was a short somewhere in the system. Now it will not power on, and I am making a leap of logic and assuming that's because it cannot charge the battery. (I've tried every single suggestion here re powering it back on, so let's move past that option.)
I note that on ebay and elsewhere there are internal charger port cables (3rd party unfortunately) that are inexpensive (as low as four or five dollars, or eight dollars for one with a small tools set). Has anyone ever used one of those third party internal charger port replacements and had success?
Thanks in advance.
Okay, I have gone ahead and ordered one of the internal USB ribbon assemblies for my OnePlus 2. But I haven't seen anyone else discuss having actually done a change-out of this part. Isn't there any hardy soul armed with spudger and screw driver who's attempted this?

If you don't mind me asking, did the phone work at all right before the replacement? Mine is a dead as a doornail, which is why I wonder. The fix does look to be easy (I watched some videos and even removed the old one, so the new install is all ready to go).

Well, we shall see if that solves my completely non-functioning phone issues or not. Perhaps this thing is just dead. My ebay seller is behind schedule as far as delivery goes, but again I will post here whatever the outcome once I do replace the usb port and ribbon.
I did promise to post a video of my install. I do not know if this worked yet (charging a newer battery; if that doesn't work I'll go back to the old battery and try again). But here is the video, which I ended up sorta having fun doing.
https://www.youtube.com/watch?v=INZUBsXXTFE
Well, I'm marking this down as a fail. The install was easy, but the phone remains dead, dead, dead. Not a whiff of life to it. The short, if it is a short as I suspect, may be in either the motherboard or daughterboard. So, not being one easily driven off by failure, I bought a working but very bent up OP2 off ebay for 70 bucks. The idea being to take its innards out and put them into the frame (and the I think working screen) of the one I have. I'll look either brilliant or the fool (I play the second one better). I will, as usual, report back.
So... said I'd follow up on the $70 ebay phone buy (the phone very bent up but somehow still working). I did get it, tested it (it did work but screen was under obvious pressure due to bend), then removed the motherboard, usb ribbon cable, and daughterboard from it and moved them into the non-working phone I was given by a friend. And it worked!! I now have a OnePlus 2 phone which is updating the rom at this moment. I'll probably root it and put a custom rom on later, but for now I just wanna see what the phone is like with the standard setup. Anyway.... it was fun to take a phone apart (2 phones, actually) and succeed at the end.

Leeco pro 3 x720 Burned USB connector

Hi Everyone!
Unfortunatelly My x720's USB connector burned few weeks ago during fast charging.. It is burned, the connector is fuzed and I feel the burning smell, but it was already too late.
So the usb port got unusable, I can not use it for charging, and I am not able to connect to my phone!
I wanted to buy a new USB flex board but unfortunatelly there is no full (factory) version on the market!
I searched it many hours on the net, but there are only cheap ( remanufactured) version of it.
They have many missed parts, just have their solder points on the board, so these do not support OTG and fast charging.. I can not understand why can't make full version boards for a higher price, these versions are unhelpful items.
https://ibb.co/kYypx8
https://ibb.co/fnH4VT
https://ibb.co/fZM9x8
So I bought only USB C connectors and I will try to replace it on the original board!
I thing it will be a hard work, but I hope it will succeed.
If not, I have to buy a used phone for parts, and I will take out the USB board from it.
As I see, the X722 have the same flex board!
So I would buy a hard bricked x722 for parts for a good price!
Just very important to me that its USB connector be in a good condition!! Do someone would sell it??
I know unfortunatelly there are lots of users who have hard bricked dead x722...
So if you read this lines and you can help me, please write me, and I hope we can make a deal!
Thanks
Daniel
Hi, exactly the same happened to me, the USB port of my leeco was burned. I do not know if it would be because of the usb cable c stock that brings (bad quality). But you'd be surprised if I told you that, shortly after the usb port c burned down, I looked more closely at port C and there was melted black plastic on the pins of the connector. Then clean the connector with a fine needle (carefully), getting rid of the plastic, the remains are cleaned with cotton and a little isopropyl alcohol (which leaves no traces when it evaporates). After doing all the above, I was surprised when I plugged in the headphones and it worked, in the end I tried another cable type C first with the PC and it worked (it was recognized by the normal PC), then I took a chance with another charger I had at home (not the Leeco charger) and it worked ... I had no problem loading it. You could try it ..!

So I bought only USB C connectors and I will try to replace it on the original board!
I thing it will be a hard work, but I hope it will succeed.
If not, I have to buy a used phone for parts, and I will take out the USB board from it.
As I see, the X722 have the same flex board!
So I would buy a hard bricked x722 for parts for a good price!
Just very important to me that its USB connector be in a good condition!! Do someone would sell it??
I know unfortunatelly there are lots of users who have hard bricked dead x722...
So if you read this lines and you can help me, please write me, and I hope we can make a deal!
Thanks
Daniel

Hi
@Kener97
Thanks for the response, I would try it, maybe it would work for me as well, but it is pretty melted..Unfortunatelly I have already disassembled the phone. I did not have another cables, but now I have two good quality fast charger USB C cables, but now I already can't try it! I happy that you can use your phone after the accident. Yeah, you're right the original cable has very bad quality. I had already thrown it into the trash.
So I decided If I have already disassembled the phone than I will try to replace the USB C port in the next week and then I'll se what can I do.
@tsongming
Thanks for the links, but as I wrote, these USB boards unfortunatelly are not the original items just cheap versions with many missed parts! Check the images!!
You can see teir solder points on the boards. So these don't support OTG and fast charging... Only the normal charging without communications. These are not an option to solve the problem. Maybe if I would replace the missed parts from the original board if the connector replace won't be suceed.. )
I will write the result!
Anyone, any other solutions? Or anyone known where could I buy the factory version boards?
Regards,
Daniel

I don't know, but the x722 and x720 is the same at the USB port and the poor quality USB cable as well!
I just recommend You don't use the fast charging especially don't with the original cable!

Thank you for the answer. Do you think the problem is the whole charge or Just the cable? Is It ok to use fast charge with third party cables?

The cables are notoriously bad, one of my x727s was destroyed by a bad cable. Fortunately, Amazon exchanged it for a new phone.
We have 4 Leeco phones in our house. I have replaced all of the USB cables with highly rated cables, that have a replacement guarantee.

So you use the stock charge with another cable?

Although some people recommend also switching the charger block. I don't agree with them, and think that is overkill. Its the stock cables that are garbage, not the the charging blocks.
We have four of these charging blocks and no issues with any of them. In fact, in late December, when the X727 that I returned had its usb card burned. My dad ( a retired electrical engineer) took apart one of the blocks and found it well constructed.
Next, Leeco charging blocks are approved by and meet Qualcomm standards.

If there was an issue with the charging blocks on a large scale, would they still provide this publicly available list? No, I don't think so.
Should you decide to go ahead and replace the adapter anyway, The pdf list has a section with Qualcomm approved chargers under the "Premium Power Banks" section

There are plenty of people with bricked X722's, go to the X722 unbrick thread and message those people, maybe some on will sell you their expensive paperweight for cheap.
If you live near a large city there is bound to be a shop that does repair at the component level. perhaps they could fix your damaged board or as you mentioned transfer the chips from the old board to the 3rd party board that has missing chips. The issue is that some of those chips are likely fried.

Hi!
No, only will work the slow charging and USB communication with the cheap, useless USB flex board!
But there is a solution, to get a new original x720 USB board with all functionality!
After 3 months and Iots of time what I spend on the net, I found TAOBAO chinese site, and to my surprise some seller selling the original version board there with a good price!
Use the Crome browser with built in translater!
Only one problem, TAOBAO is a chinese "domestic site", and nobody ship to abroad.
But I did not give up! And I found the final solution, that's Yoybuy! (Yoybuy.com)
Yoybuy is a forwrding site!
You can buy everything form chinese sites helped by Yoybuy, for a cheap price!! From Taobao or many chinese site and you can use it English.
Just register at Yoybuy and copy the Taobao item's link to Yoybuy and they will buy the items, what you want! You can pay by paypal as well!
I hope I could help you! My phone is back to life, and it is like a new one!
Regards
Daniel
PS. Definitely buy a new good quality USB C cable for charging ( I recommend You the Oneplus DASH cable) to stay the USB connector intact!

Hi, exactly the same happened to me, the USB port of my leeco was burned. I do not know if it would be because of the usb cable c stock that brings (bad quality). But you'd be surprised if I told you that, shortly after the usb port c burned down, I looked more closely at port C and there was melted black plastic on the pins of the connector. Then clean the connector with a fine needle (carefully), getting rid of the plastic, the remains are cleaned with cotton and a little isopropyl alcohol (which leaves no traces when it evaporates). After doing all the above, I was surprised when I plugged in the headphones and it worked, in the end I tried another cable type C first with the PC and it worked (it was recognized by the normal PC), then I took a chance with another charger I had at home (not the Leeco charger) and it worked ... I had no problem loading it. You could try it ..!

I think you make a good point about the the LeEco charger. Precisely, it is the cable that is the biggest culprit. I recently bought a x720 and had it for a week charging with an old charger and cable of my le 2. One day i couldn't find the le 2 charging cable so I decided to use the one that came with the pro 3. Just seconds after plugging the cable in I smelled burning plastic and could see smoke coming out of the usb port. I removed the cable and could immediately see that it had melted on the pins close to the edge. Funny enough, if i plug this burnt cable on my le 2 it is charging but if i plug it into the pro 3 it gets hot and starts to produce smoke. I have tried with other type c cables and the port is burning them also. Now it looks like I need to replace my usb port. I will have a closer look at it to see if it can be cleaned but I'm not hopeful. I hope i can get original parts for it because i was sold an old phone by an AliExpress seller who claims it's new. I have started a thread on it. Hopefully I can spin it out to ask anyone with information about where to get genuine parts to help restore these old phones.
