HELP USB Miniport Broke
Can someone help I have an issue, I broke my usb port, I have the phone opened, I was able to access the usb port it has been completely broken off the board, seems to be broken of clean no cracks on the board, all I need is the usb port does anyone know where I can buy a miniport? Also the correct size of the head for the Soldering pen? Is there anything else I may need to repair this issue. Keep in mind I have the phone open, and Have the ability, but if there is any more steps I may use I would really appreciate it. Thanks

Is this a common problem? Mine is now loose, and it will be so annoying of it breaks off the mobo.
I don't know anywhere where you can buy the miniport, but surely warrantee will cover fixing the miniport?...
I did almost the exact thing a couple days ago. I only noticed now from this post. My pins were bent but it didn't break. I had to bend it pretty far so my charger would work again. Do you have pictures of what it looks like from the inside? Maybe you can buy a cheap device with the same pin layout?
No Picture
No I dont could take one, the usb port broke off the board I have talked to PocketPCTechs.com They will sale me a USB Port for $25.00 dollars I wish they had a picture of it maybe I will call them for a picture. They also said they will fix it for $79.00 dollars. I would like to do myself but for 79.00 dollars well I think it is well worth it.
I had the same problem 25 for the part 0 for a local company to put it in. pocketpctechs does give you the mogul usb port which I think is better than what comes standard on my kaiser. (humorous fact htc wanted $350 and 3 wks to fix it)
its not covered under warranty its considered misuse
http://wiki.xda-developers.com/index.php?pagename=HTC_Kaiser
there are disassembly pics somewhere on this page, if your comfortable soldering it shouldn't be a problem. did it w/ my 8525.
Hey maybe you can extract the port from this:
http://cgi.ebay.com/New-HTC-MINI-US...ryZ20336QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
I get one like the one I posted and it has the HTC symbol on it and everything. It looks OEM to me. Well the mini usb port on there to where you can plug in the headphones has all the pins on there and it seems like you would be able to just extract the one on the adapter for much cheaper. (around $5)
HTC repairs
I recently sent my kaiser to htc repairs USA austin tx and had to give them my credit card number. Anything they find broken not covered by the warranty they fix for $28 which seems cheap since you know they will repair it the right way. Also its oem parts
Hey I am currently living in Austin, TX for school. I just have an ATT Tilt and am not with ATT so I am probably not covered by anything.
damn, smaething happened to me , but it didnt broke off the phone, now that i look at it the usb thing its bend, now I know why the charger didnt want to plug in yesterday...
HTC has a one year warranty and as I stated befor they will fix non warranty items for only $28. That is what I was told when I sent in a Tilt that was not with AT&T.
I think mine must be bent or something too. The USB goes into it to charge, but it falls out really easily. It's not as big of a deal if i am charging it at my house and just leave it alone. The problem is when I'm in my car and it moves around and the charger falls out when it just slides a little bit.

Thats how it started with my apache, now it doesnt charge at all. I found a site on google, search for PPC techs and they do the repair for $60, but you have to be without the phone for that time.
Tilt port repair from HTC USA
Called them about a port repair and was told it would probably be around $350 since it is part of the main board. Might be covered under warranty, up to the technician to determine if it is a normal failure or customer caused.
Too big a crap shoot!!
I just had the same thing happen, and they also told me it was "user error" and that it would be $300+ to fix...... this is clearly a manufacturing/design error and should be covered by warranty!

Just bumping this thread because I have the same problem. One of the metal pins inside the usb port ended up being "pushed down" so my phone wouldn't charge/connect to activesync.
It might be time to move on from an HTC phone, I guess.
The phone was a refurb though, and I've had it for 8 months.
Hi guys.
I dropped the phone, and know my phone only charging. (PC can't see my phone any more)
I called to US Samsung center they said to call in Europe lol, because they can't find my phone.,etc.
So guys I need to buy new USB port, to fix damn Note.
Where I can find this part
Thank you for helping.
Best regards.
Hi, sorry to hear about your phone but I don't think you should fix your phone with your own money, the phone comes with a 1 year warranty that should cover such stuff and I'm guessing because the phone is not available in the US yet you might want to go down to a Samsung Customer care to see if they can get it fixed or else I'm afaird you have to do it yourself
BTW which country did you buy it from?
Composed on my Samsung Galaxy Note using XDA Premium app
I'd get a battery charger on ebay asap. Your phone will go flat while you wait though.
Its not a good plan to try your own repair. Its probably a broken solder to usb socket but might be something else and then kill your waranty.
So try to get Samsung to fix it. And a couple of batteris to keep you going till then with external charger.
no understand
Are you saying its charging or not charging?Is the phone rooted if so you won't be able to send for repair, and as your PC can't see it you won't be able to unroot.Try cleaning USB port with nail varnish remover and tooth brush without Battery inserted and leave for 20 minutes to dry.If its not charging then maybe connector has popped off.Its easy to fix just have to remove about 8 screws takes 10 minutes I've done it twice.There are how 2s available on the net.I've looked everywhere for USB port they aren't available yet but toothbrush and nail varnish remover fixed it for me.
i doubt if its a broken solder contact. I think the flex ribbon connector has come loose. if you will open up your phone, then you should just reconnect the flex ribbon connector and your phone should be ok.

Last time I checked manufacturer warranties don't cover "dropped' phones.
There are US service centers that fix phones for a fee.

Hi guys. I recently used a questionable charger with my phone (leeco le 2 x526) and since then it has been problem after problem with the USB port. Immediately after that charge, the phone stopped charging with the supplied quick charging brick. It won't even charge slowly. The phone behaves like the charger is being plugged in and out about five times and then completely stops as if the charger is no longer detected. However ,when I put it in a normal slow Samsung charger, it charges to the end without disconnecting.
It's not only the charging that's not working. A Windows PC I have connected the phone to before doesn't recognize it so mtp doesn't work. The PC says the device has malfunctioned and windows does not recognize it. Lately the phone has started rebooting randomly so it seems like I need to fix it soon.
Also, when I plug in headphones using the 3.5mm dongle, I hear crackling sounds for the first few seconds and Jack detection doesn't work sometimes until I reboot. Sounds play okay when it's detected. The microphone and media control buttons on headset have stopped working and I hear static when I press the buttons on my headset, sometimes it's quiet.
I'm pretty sure the USB board is the one that's damaged but want to know if anyone else has faced this issue. If it's the USB+mic board that's damaged I'll order one on AliExpress. I found it for like 8 bucks.
I'm thinking I have a hardware failure because since it started acting up, I tried to flash a ROM clean and got an error in TWRP. The flashing finished but I saw a red error message:
Code:
rcv error in uevent
I googled and this error occurs when the kernel fails to initialize a hardware component.
Has anyone experienced the same problem? I don't want to replace the board without a second opinion.
I believe that you are definitely on the right track with the replacing board, this same exact issue happened to me once on my first Leeco X727. In my case I was lucky enough that Amazon agreed to exchange it for a new phone. Without a doubt, many Le Pro 3 owners have seen this exact issue. Your questionable charger possibly shorted out the USB card.
I would strongly suggest that you replace the battery, while you are at it, it will also be very cheap.
You will need to use a Heat gun to remove the display without damaging the LCD, there are many videos on youtube that demonstrate the quick sweeping technique and the glue will easily release enough that the screen will come off simply by turning the phone onto its face side.
While you can also use a hairdryer, you will need to run a guitar pick along the edge of the screen to remove the display and it's very easy to damage the LCD...I did! Consequently, I bought a heat gun at harbor freight for $ 7 dollars, to easily the display on a friends X720.
Good Luck.
PS : Did you receive your Le Pro 3 yet?

Thank you so much for this advice. I will replace this board and see if it solves the problem. About the heat gun, I don't know if I will use it much after this repair so I'll take the phone to my friend who has a repair shop to change it for me.
One quick question... Is there a high possibility of damaging the battery during this repair? I don't want to replace it if I don't have to because mine is still pretty good and keeps like a new one. I don't have much luck with AliExpress because the original batteries for Le 2 cost almost $150 to ship. The rebranded batteries cost less to ship (~$10) but I don't know which one is reliable.
My Le pro 3 is still in transit. I reckon it's still about 2 weeks away because shipping takes very long to my country. I'm just now going through the various development threads to find a good ROM for it. Thanks again -- you're a godsend ???.

No problem.
The battery is underneath the heat shield so it will not be affected by the heat gun.

I flashed a ROM from 4pda and totally messed the phone up. That ROM failed to boot and to make matters worse, it formatted my data partition. Everything is gone including my backups and I cannot transfer a new OS to the phone because my USB port doesn't work. The only thing I can do now is to shelve this phone until the replacement USB board arrives. You have been of great help and I appreciate it extremely. I'm using a feature phone now until my pro 3 comes. To use any Android app I have to share my wife's phone which just sucks. (She barely puts the damn thing down)

No doubt we never realize how much we rely on these devices until they are gone.
You will definitely love the Le Pro 3, it is much more powerful, and the camera is phenomenal.

Absolutely true. I have a new found appreciation for my phone. Now that I think about it, with the time I spend on it I think some digital detox is in order.
I received the USB board from AliExpress but it is incompatible with x526. Anybody with information on where I can get a board for x526 please share it here. All USB boards on AliExpress are for x620 and they can't work on x526.
I am actually thinking about looking for the x526 board in India because that's where the phone was built for. I just haven't figured out how to go about it. But I reckon there is a lot more need for spare parts there because of the high number of people using the phone.

My le 2 is finally back to full working condition thanks to you. This USB board doesn't look used at all. The best part is that mtp and fast charging are working again.
I have a Razer Phone 2 with the infamous non-working USB C port. There seems to be very little supply for the board itself unless it's a used part and those seem to be farelt expensive. Looking at a teardown video of the phone it looks as though the port itself is attached to a flimsy ribbon type cable attachment. If anyone has any experience with this specific part could you please tell me if there are solder points that could be either reconnected or replaced with a completely new port without replacing the whole board? A friend of mine has a a fair bit of know how when it comes to doing repairs of this sort, but I'd hate to take it apart to try and replace the port it self and risk damaging the seal of the device for no reason at all if this procedure is not even possible without a replacement of the full part. Thank you in advance for any replies. I know this question might be a long shot, but we are just trying to weigh our options and figured someone on here might have the experience to point us in the right direction.

I have the same problem. And since sending it back to Razer( don't get me started on how much there customer support sucks!) would cost more than buying a used phone 2. I am thinking to replace the port. Did you have any luck?
I work in a repair shop where I get these from time to time. You can try a used charge port board, but that doesn't always fix it and that seems to be a temporary fix. I have yet to find the root cause of the charging bootloop on the nearly dozen rp2's I have
Hello guys,
I have an old Samsung GT-i9060 phone which I'd received from my previous employer. It has finally given up and is now completely dead. I suspect a faulty charging cable to be the culprit this time as my attempts at superficial repair has proven that the problem is deeper. I tried getting it fixed at a local repair shop but he gave up on the basis that parts aren't available and that the motherboard has gone kaput.
So, to summarize....
Samsung GT-i9060 completely dead
has been dropped several times and cracked digitizer has been replaced.
old battery is not at optimum condition but problem persists when tested with a new battery.
No vibration or samsung/charging logo on display when powered on battery or charging but certain areas of motherboard get heated up if I try to turn it on.
I got some important contacts and backup on this phone which I'd really like to salvage. I invested in a few basic tools and looked up a few tutorials on the interwebz but none seem to help me understand the actual problem. I am a novice when it comes to electronics and can easily try to recover the data through some specialists but the satisfaction in getting it done myself is priceless!
So any kind of help would be immensely appreciated.
Thanks
Make sure that the battery voltage is over 3.6 volt. Then connect phone to pc using usb cable without pressing any buttons then check pc detects phone's soc(broadcom interface) or not.
Thanks. Let me try that out and get back to you.
Update - @engage4 Battery was at 4.27V, fully charged. Connected to PC but it wasn't detected although I observed the same heating issue as mentioned in my original post (see attached pic)
Coincidentally, the memory chip and processor are on the exact underside of the mobo area that I have highlighted (which heats up)

So you already tested with a new battery. Good! That's one of the first things I would do as well. GSM Arena says the battery is "Li-Ion 2100 mAh, removable". At least you didn't need to send it in or leave it to a repair shop to replace the battery. I remember the time when you could replace the battery of your phone yourself. That in itself was very satisfactory. Those were great times! Those times are gone. Now you have to pay a premium to replace a battery. It's "complicated" they say, and so it's not for everyone (or anyone).

Hotter than what's usual for a phone that's charging? If it's shorted, charging may damage it further. You can test it of course, but you're risking it. Don't test charge for longer than you need to, preferably not at all as soon as you realize there's something wrong with the device. There's the risk of battery leaking or catching fire. So be careful and don't leave it unsupervised.

What kind of tutorials are you reading or watching? What do you think is the problem?
You have to go over more than a few tutorials if you want to be able to intuitively know what to look for or what to do. One way is to start learning about electronics in general, experiment and learn, before you get down to this specific problem. Another way is to start exploring from the repair side of things and work your way into the topic of electronics repair by troubleshooting this specific problem.
Your problem is most likely caused by a short somewhere on the board. So I would suggest you learn about short circuits or "shorts" for short (duh) and how to find shorts in general, and then work your way down to how to find shorts on mobile phones specifically.

I know that feeling. I'm wired the same way. If I can, I will try to repair and fix things on my own. Sometimes I will take on things I hardly know anything about. I will try anyway and learn in the process. Some things are admittedly more difficult than others. But that's how you learn and grow your knowledge base.
People no longer repair things. They throw out the old and broken things, and just keep on buying new things like on conveyor belt. This is not good in by any means. The biggest negative impact of this I think is that people stop using their head. They begin to believe that everything in the world is automatic. A light bulb is the result of true magic, especially when you throw in smart home plugs and switches into the equation. People are slowly being turned into slaves of consumerism. Common knowledge diminishes, like what household products you can use to remove stains, and we only live to serve a higher purpose of capitalism.
Do you have the service manual for this phone? You can usually find these online free of charge. Do you have a multimeter? The first tool you should buy and learn to use is a multimeter. Learn about the continuity test, diode mode, and how to measure voltage.
I worked as an electrician and I felt like I had to ask about how to measure voltage at a resistor, because I was unsure and didn't want to risk damaging a board more than it already is. As an electrician, I worked with voltages relative to Earth ground. I never worked with electronics, although I did get basic electronics training and I know all the basic components and how they work. We worked with soldering iron as well, and learned to use an oscilloscope. I was best in class at soldering. This was a long time ago though. We programmed PLCs, made Delta and Y-configuration connections of three phase electric motors, worked with relays and contactors, and we learned a whole load of other useful things.
My point is, always ask someone more knowledgeable and experienced if you're in doubt about something, rather than taking a risk or gambling. This is much more important of course when working with unforgiving high voltages and high currents, so as an electrician I learned early on to respect electricity. This was all part of my training and thankfully I have never had any accident. It's OK to make mistakes, and you're bound to make mistakes when experimenting, but you better have a backup plan and put in some kind of safety net, to protect yourself and to protect your equipment or whatever it is you're working on.

The USB connector on the charging cable I was temporarily using sometime back had a flimsy connector and I suspect the loose connection might have caused 'spikes' and maybe shorted some components/mobo.
I had dropped this phone on numerous occassions and almost everytime the ribbon connector for the LCD would come loose since the connector on the board was a bit wonky. I used to check this and get the phone working again. This is what I meant by superficial repair.

Now that you mention it, one of my charging cable was a bit flimsy as well. Might be what happened with my phone as well. The connector would wiggle left and right so I would have to make sure it points straight into the port and rotate the phone left and right to make sure it's not tugging on it as I put it down on a book shelf. I always charge my phones on this book shelf as the power outlet is close by.
I have actually four identical Samsung 15 W chargers sitting there, all for the Galaxy S7. Three white ones and one black, and each with its own charging cable. I had purchased some extra chargers just as spares, and one of the chargers had a bit flimsy connection, as you say. I actually once spotted that one of the 4 pins on one of the charging cables was too short, and because of it, it was not charging fast enough. I stripped it down to bare wires, all for science and learning, before throwing it away.
On another occasion, I discovered that one of these cables didn't want to charge my phone when combined with one of the four chargers. It was a perfectly fine looking cable. The same cable worked well on the other three identical chargers though. So this was a bit of mystery I had never seen before. That will remain a mystery. That same charger also worked well when combines with other cables. So both the charger and the cable worked well, but only with others, not with each other. Note that these were all original Samsung chargers and cables. The "travel adapter", model EP-TA20EWE. They all came in original Samsung retail packaging. Although the spare chargers I purchased did have a bit stiffer and thicker cables, when compared to the original that came with the phone. They were presumably made in later years, so Samsung had probably changed them up a little bit.
But this goes to show that there is more to a cable and a charger than meets the eye. I suspect it had something to do with lack of compatibility across the many charging protocols that are in circulation in the fast charging universe, like Qualcomm Quick Charge 2.0 vs. 3.0 vs. USB Power Delivery 2.0 vs. what-have-you.
So you're not wrong to suspect something as "simple" as a charging cable. Not even a cable can be left alone, they have to make it "smart" and complicated. If the cable doesn't know how to talk the language of the charger, it's useless. Or worse, it can destroy a device. All because industry wants to satisfy inpatient people that want fast charging, and so instead of 1 standard, they make 4 different ones, if Apple Lighting-whatever is included. By the way, the faster you charger a battery, the faster it will lose its capacity and die out.

Nah. He simply didn't bother about repairing or even replacing it on the basis that parts are hard to come by!

That depends where you look and how determined you are.
I ordered a new S535 power IC for my Galaxy S7 from Germany via Ebay, and I received it last week. I don't have the exact dates, but it arrived within the same week, so about three to five days. From Germany to Sweden. I also ordered three of the same chip from a supplier in UK, also via Ebay, and it has yet to arrive. This has to do with Royal Mail strikes, so everything is delayed. In addition, I had to pay customs fee and import tax from the UK. Not sure if it will be held at Customs service and delayed even more because of this, or if it will be delivered straight to my mail box since the UK supplier made sure I can pay upfront so it can be cleared for delivery. So I will have 4 of these in total.
Let me give you another example. I have an older car that's well looked after and only driven occasionally. A few years back, it started leaking oil from the rear axis. I went to the authorized repair shop. They told me they had to either replace the differential or rebuild it. But because it's an old timer, there are no parts for it readily available. This is a BMW car and BMW has a good reputation for stock keeping parts for old models for a long time. Well, maybe they don't keep a stock of big parts such as differentials. But it's not true that it's not available. I looked it up online and found several car stripping companies that have a number of these parts to pick and choose from, some of which were in almost new condition. So if they really wanted to, they could have ordered in from there. This is where small and independent auto repair shops order from as well. I even offered to order it myself and deliver to them. But they could not make the needed arrangements. Or rather, they didn't want to. I understood the message. They can't be bothered with something as heavy, oily, dirty, difficult, skill demanding, and time consuming as a differential replacement... and a rebuild is probably as distant as science fiction to them. I never went back there. I used to go to them for years and was always happy. Since they changed the owner and relocated, it's a completely different company. I would never again go to an "authorized" repair shop. They are properly titled "car dealers", because they are more interested in selling you a new car or a used car than repairing your old one.
It's the same with phone companies like Samsung and these places they call "Support Center" where you can walk in to get support and service on the device you already own, and they put up their latest "flagship" models on display and under your nose. That's how you know you're in the wrong place. It's all sell, sell, sell.

I have invested in a multimeter, soldering iron and supplies and a heat gun. I do also have a manual for the phone and it has helped me partially.

Make sure to get the needle-like test leads for it. This is needed for probing and measuring tiny components. The ones that came with my multimeter were very good, but they were not fit for the job, because they are not thin enough at the top. Most of the standard test leads have blunt tips. I ordered a pair from Amazon, a complete kit actually, but they are not very good. The whole kit was very cheap and I could not find any other, higher quality, more expensive ones. I don't want to promote Amazon, but I can post a link if you want.
A heat gun might work, but a hot air station is better. You need about 350 C to rework big components like BGA chips. Based on my limited knowledge, but extensive research. You should be able to tell what the temperature is at, and only the more expensive heat "guns" will have a temperature sensor and a digital display.
A service manual is a good resource. I wish I had a complete service manual for Galaxy S7. I looked for a places to buy one but I only found dodgy websites that seemed to be in the business of downloading free manuals, packaging, and selling. So if you have a complete manual, that's better. I only found excerpts of the most important chapters for Galaxy S7, and it has been very useful.
So, umm, there has been no progress on the repair front as I had been away on a trip and got my phone stolen
I was a bit occupied with reporting to the authorities and blocking my phone number hence I couldn't reply earlier.
Btw, I stumbled upon something called as boardview bitmap files; I'm yet to fully explore it but it seems really helpful.
