The female USB mini connector on the device-side of my MDA Pro broke off and fell into my MDA Pro! This happened when I inserted the original supplied travel charger. My MDA Pro was four weeks old and I have never ever dropped it or damaged it in any way. It was even completely scratchless as i am very carefull with this very expensive machine.
I sent it to TMobile ProAssist, thats were the devices get repared. After one month, I got the message this problem is a "User fault" and it is not part of the warranty!!! I could choose: Have the device repared for 480 euro's (replacing motherboard) or returned at no additional costs!
I am very angry at TMobile Netherlands, as they keep saying this is just not covered in warranty... They also say that the connector is very solid and can not break off without intervention of the user. But still, it happend to me in a routine process like charging!!
So i have the following questions.
1) Is there anyone who has also experienced problems with the USB connector on the device?
2) I figure this is a designflaw or productionfault and should fall under warranty, no matter what the people at TMobile say, right? Or why not?
3) Has anyone experienced more trouble with TMobile as repaircentre?
4) Would another operator repair this within the warranty?
5) Is it me or is it madness to replace a motherboard for 480 euro's on a device that would costs TMobile like 400 euro's new?
Thanks, you are all very well appreciated in advance for your reactions!
They are lying. The connector is known to be weak, and has broken of for a number of people already. Search around a bit more and present them with the evidence, and threaten to take them to consumer court.

I complained about my connector breaking off on pocketinfo.nl. There were several others there with the same problem and I saw more on this forum.
I fixed the connector myself (I was in a hurry) so I know for sure that it is stuck on really badly. This IS a construction (or design) fault. It's only hold down by a tiny amount of solder. Completely unacceptable for a component that will be under so much stress.
The trouble is that it can do a lot of damage. In my case it damaged the wiring for the usb connector (it ripped a line off) So it can be very costly for them to repair if they need to replace the motherboard.
Happened to me too, fortunately I have Insurance provided by o2 and they sent a courier to my house to exchange it the very next morning for free.

Patrick, are you also the owner of a MDA Pro? Isn't it very weird that TMobile Netherlands doesnt consider this as a design flaw, while other providers such as O2 are conducting repairs under warranty? This is outragous.
Is there anyone that knows about laws in Holland/Europe about warranty and designflaws? Can we make a stand?
yes, mine is an mda pro too. I'm guessing mine worked lose from using the charger in the car. There is a lot of vibration on the cable that works it's way into the mini usb connector.
One morning I took out the usb cable and the connector came off and dropped back inside.
I didn't check it for warranty since I didn't want to be without my phone for a few weeks. I was just about to go on holliday for a few weeks too. So I repaired it myself. It wasn't really difficult, but you should be able to work with SMD components. I only fixed the charging though. One of the signal lines was ripped off the motherboard.
I have the same problem with my Logitech Harmony remote. I guess these mini USB connectors are the cause of the problem. They don't come with mechanical fastening or something. What kind of freaky designer uses solder for fixing mechanical components? Or at least they should use more of it. Mine was attached by the lines and maybe 2 tiny pads at the sides.
Anyway, I digress. I have no idea how you can convince T-Mobile. Guess that's where the problem with warranty is. Sometimes you don't get warranty unless you "sue" them, but then that's not worth it either.
It's pretty obvious that putting a cable in and out of the usb port is "normal use". Maybe if you say yyou dound lots of others with the same problem you can get it repaired under warranty. Ask for their manager. That might help too. or is that an american thing?
I still use a Sony Clie NX70 to read books on. That thing is built like a house. The hinge is still great and the metal housing keeps the screen from getting cracked (two other known design faults with the MDA pro) It really puts the MDA pro to shame. Just wish Sony was still making PDA's.
Goddamn im angry. T-mobile just called, all they can do is exchange my MDA Pro for a Nokia 6230i. Not over my dead body! :x
Is there anyone that has gotten it's provider to repair this flaw? If yes, can you post your RMA/reparationnumber here? I can use these numbers as evidence that this is a flaw that needs to be covered under warrantee.
Please give me your RMA's and your provider/brand/country. Thanks very much!
Wow you mean they can't even repair it anymore? Is that because they don't sell the MDA pro anymore. Or is it because you want it repaired for free?
They CAN repair it, but just not for free, as this problem is not covered in warranty. In the price offer they have sent me, they suggest to replace the entire motherboard.
I think, with a repair price of 480 euro's, it's a total loss. I'm affraid the sum of 500 dollar is too low to take this into civil court or even to let a lawyer take a look at this. So next thing what i'm gonna do is write a lettre to the CEO of T-Mobile Netherlands.
replaced under warranty reciept attached
I grow tired of this problem; I made them aware of the situation quite a while back.
though I agree that it would be just to expensive to replace every unit the company should at least replace the broken ones.
Attached is my receipt showing that Imate did replace mine under warranty for free,
I have kept my personal details on the receipt for legal reasons for everyone else.
I hope this helps.
btw- I was sworn at, I was lied to, I was made to go through useless paperwork and there website chat programs are down most of the time and even when u do connect u have to endure a person who cant even grasp the basics of English. I feel sorry for this company, they don’t understand the basics of business.
Thank you for the receipt one piece more to show T-Mobile that a device design error should fall under warrantee. I have heard numberous of bad experiences with iMate customer support, as I also sell iMate phones at my company. Would never even consider to buy one.
There HAS to be somewhere that has a T-Mobile repair receipt regarding an USB connector.. so if you're out there, please contact me!
Hello,
After some years of heavy usage, my gf's HD2 has finally given up. The USB port has completely come off the mainboard, so I disassembled the device and found that three pads have been torn off, atleast partially, in the process. I am now facing two options:
a) work some soldering magic to reconnect the USB port to where it belongs, and glue it down using epoxy resin.
b) send the board to some kind of re-padding service.
I'd rather go for b), since I am not 100% sure about having sufficient soldering skills. I've already done some small-scale soldering (0603 LEDs) in my life, but am in no way trained and only have access to basic equipment at home. The problem is, I'm not sure where to send my phone to, also I worry about the costs of it being possibly higher than buying a "new" HD2 (and YES, I'm totally going to buy her another HD2 because this device absolutely ROCKS, thanks to the awesome development done here on XDA).
What do you recommend? Has anyone ever managed fixing their USB ports on their own? Do you know of any repair service that could fix this for under <40EUR?
P.S. I'm from Austria, so shipping outside of the EU might be rather expensive and is not really an option.
Thanks in advance for any advice!
Bought a Htc Hd2 of eBay on Friday but it had a fault which caused it to freeze or overheat from time to time the seller said it was a PCB Board problem
Quote from ad ''DUE TO ONE RECURRING INTERMITTENT FAULT WHICH MAKES PHONE FREEZE UP OR IT OVERHEATS LEADING TO IT TURNING IT'SELF OFF WHICH FROM WHAT I HAVE READ IS DUE TO A PCB BOARD ISSUE WHICH CAN BE FIXED IF YOUR TECH SAVVY WITH MOBILE PHONES (WHICH I'M NOT!) ''
so i have a few questions
1. Can anyone confirm this ?
2. Where can i get a replacement ?
3. is it worth it?
Never really done any hardware mods or anything to do with hardware just software so any help appreciated won't forget any help given
CPU BGA faillure, Can be reworked but not worth it. needs a replacement mainboard, you may find a broken screen hd2 cheap on ebay for donor board then sell rest on for parts.

Hi everybody, i need help about replace the motherboard of my galaxy note 4. I will do it because i think that the eMMC of my device is completely messed, i've tried everything in modding but nothing help, the device it's barely usable, it keep rebooting and it lag, only if i use the app to keep the cpu awake it's usable. Plus it doesn't read the sim card anymore. All started when one day, totaly random, it do a factory reset by itself and i lost EVERYTHING in the phone. So i see that on aliexpress they sell motherboard for my n910f, if i buy and replace the one i have now, it should all work without any problem? thanks for any advice
ps: sorry for my bad english, i'm italian

I can confirm that once you get the eMMC read failure messages there isn't any coming back from it unless you either A) Replace the eMMC itself or B) Replace the Motherboard. Since trying to micro-solder an eMMC chip would be way to difficult for most people out there (myself included, I cant solder for s***) the motherboard replacement would be the way to go.
I did try all the "fixes" here on XDA I could find, but none worked. Flashing the full recovery software in Odin took AGES (15 + minutes, it never took me that long, plus then 20 minutes to even boot)
Finding the part is one thing, installing it is another. I have never tried replacing a phone motherboard but my main concern would be if the board is unlocked, or atleast knowing the carrier it was locked to in order to get a valid unlock code somewhere online.
I was told by a few repair shops locally that its totally possible to replace the motherboard but there was a risk the screen would also break (So a replacement may be needed there as well). Honestly it might have been that they just didn't have very good luck with taking these Note 4's apart without damage or they just were inexperienced. But in the end for me when my first Note 4 hit the eMMC error, I sold it for parts (sPen, Screen, battery ect) and bought another Note 4 second hand
Theres a ton a speculation about this chip issue, be it heat killing them, consistant flashing or just a bad batch of chips used and now failing over time.

thanks for the reply! ok so, i must have to buy the motherboard. I've find one interesting on aliexpress, 55$ and full unlocked (at least they said that), replace it isn't very hard cause you don't have to take the screen off, just the rear parts of the phone (i've already did it when i change the headphone jack), so Tomorrow i order it and when it arrive i will tell you if it works i hope so at least

Best of luck with it and hopefully the swap goes well. I probably could have tried finding parts but the 910W8 model is different I guess.
I have replaced a mainboard with one from aliexpress, which generally worked fine, but for done reason my gps didn't work. Not sure if that was a problem with the board or just some connector not during properly?
Regarding the emmc error, I've actually managed to revive the old board after it had been sorry of bricked by the previous owner in a failed flashing attempt by putting it in the fridge while flashing the firmware with Odin (on xda someone suggested this, they actually say to put it in the freezer for a while, but I don't have a freezer and putting it in the fridge and taking it out for flashing want enough). It still has the error, but seemed to run relatively ok with a wakelock app preventing the CPU from falling asleep.
Though I get your idea, it feels safer to have a fully working mainboard.
The only problem buying a motherboard is from other sources other than Samsung you not sure if the MBA are brand new. I would say go to Samsung and pay for a new MBA and they will write your original serial number and IMEI to the new MB and you get a warranty..
Just replaced a mainboard...
Bought more than a year ago a faulty Note 4 thinking it was one with a faulty screen as the blue LED and vibrator would come on while pushing the start button and the phone was recognized by my PC. Turned out to be a faulty MB and while trying to replace the MB I damaged the screen.
So I ended putting all on the shelf. Meanwhile bought a note4 for my wife and figured that the spare MB could serve her phone in case it would go bad...Then recently stumbled upon a faulty note 4 where the owner claimed it was one with a faulty MB. The asking price was ok so I ended up buying it and fitting the spare MB. I was lucky in a way that the previous owner already swapped the display so it came apart very easy. I did put all in place using the OEM tape ordered specially for the Note 4. It is a fact that this MB is manufactured in Feb 2015 so it could be well that in the near future it fails although when checking the chip with the app it tells me I have a sane ship...

You should search for videos on replacing the MB in the Note 4; it seems to be fairly involved and you run the risk of causing additional damage to your phone.
Samsung in the US is replacing MBs for about $50 to $150. I got mine replaced (plus a bunch of other repairs) for $70 (which is about the same cost of a MB through AliExpress). Samsung paid the postage for me send my phone to Samsung Service in Plano, TX, they then diagnosed the problems and said they would fix it for $70 or they would return the phone without repairing it at no charge. My phone was over two years old and out of warranty. I had them repair the phone and it was returned in like new condition and it is still working great. The entire process took about 10 days.
You may want to contact Samsung Customer Service directly (in the US call 1-800-SAMSUNG) and see if they are willing to look at your phone and hopefully make any needed repairs.

Thanks for the info will try it, my note 4 will not even
finish booting anymore. It is alteady out of warranty hope they don't mind it is rooted.
There are plenty of video's on you tube on how to. Look at them, look at different video's to get as much info as needed. Don't mess around with you screen, just replace the mainboard and you will be ok! Mine still goes very strong, its GPS is working very well even indoors. I owed a few Note 4's and this is the first one where the GPS is usable. Putting both note's side by side...well one GPS gets a fix and the other one.......well is useless! Did the same with a Note 2 where I replaced a faulty mainboard and this thing has the fastest GPS I ever seen. This Note was due to be sold but I have decided to hang on to it a bit longer...
Hi I am Samsung Note 4 user I have a problem since yesterday it is not registering on 4G or Lte Network only 2G is working. I tried lot but could not fix this problem. I changed the setting LTE/WCDMA but still it is not registering. Can and body helps me to resolve this issue. even I format my phone also by the problem could not rectified. I visited Samsung Center they are saying there is problem in motherboard. for replacement it costs 280$ in India which is very huge.

$50 to $150 is a pretty big range considering whatever caused these issues is originally still on Samsung itself for cheaping out. I thought about going the AliExpress route but I've never bought from there before and their site isn't the easiest to navigate...seems every seller with reviews is selling used boards (questionable lifespan?) and the ones with no reviews appear to have brand new ones, but are these brand new with the same old issue, so we're buying boards with borrowed time or is there a chance they're ones that won't have this issue. One could only hope that the new ones via AliExpress AND the ones being installed through Samsung have been revised to not have this issue, but we may never know until it takes a dump in another 3-4 years like the original phones appear to last.
I bought my phone used via Craigslist, so I hope that isn't their justification for additional gouging.
Hi all,
Looks like this guy on YouTube was experiencing the EXACT same issue that we're all experiencing (random restarts, boot loops, bricked phone, etc.) as a result of motherboard. I'm thinking about ordering one of the N910T motherboards off Aliexpress and hope for the best. I can't even restart my phone anymore...and I know my phone batteries are fully charged.
Seems like it works...I'm just nervous about taking it apart!
Regards,
Jeff
HI
i had troubles with my Note 4 lately, blocking and restarting randomly,
baked the motherboard in an oven and it worked great again but only for a 1 whole day then it only shows blue notification light when trying to turn on,
tried the baking today again at a bit higher temperature 200c for 10 min,
and it is completely dead now,
i am looking to buy another 910F board but reading the feedback on aliexpress seems like they are all baked, people are not satisfied, it works for a very short time,
dont know what to do,
can i put some other version like 9100 dual, some other that has better chips(not heating so much) exynos instead snapdragon or something like that?
Hi Community,
I tried as hard as I could but at this point I've basically given up.
The Problem:
Phone USB-C Port was damaged while charging overnight (Bad LeEco Cable). Over months with a few shipments from aliexpress I tried to repair it, damaged the screen during the process etc etc...
I changed the USB-Board as well as the damaged battery, sadly it's still broken. If I plug it in nothing happens, no detection or anything, charging works though! I unpluged the data line on the flex cable and the behaviour is absolutely the same. This leads me to the conclusion that the power line is ok but the data flex cable or something on the motherboard is "fu**ed". I also tried an EDL Cable as well as an USB Stick. The USB Stick gets powered but not detected by TWRP which is luckily still installed.
Is there any way to safe this phone or into the trash it goes? Thanks in advance to the community, I've been an avid reader for the past couple years and the solutions always suprise me
tl;dr Charging works, data not so much, any way to get something on this phone?
BTW: I don't want to buy a Jtag Box or something else that is 1 time use and 20$+
Thanks so much in advance!
Hi
Never give up, always there are solutions just you need to find it!
And yeah, you're right the cheap quality original leeco cable made this big problem as You say.
We already talked about this problem, because my phone's port was burned as well, but I could repair it, with an original USB flex board.. So now my phone stayed alive and he is just like the original one
I think won't be good the cheap fake Usb boards from aliexpress.. etc.
You need only the factory version!
Please check these topics, I have written there the solutions!

Thank you very much! I hope there really is a difference between the boards you can get from aliexpress and the one you get from taobao. Gonna order tomorrow and then wait :highfive::good:
Would be pure bliss if I can get this phone to work again.
Edit: Could you post the Taobao Link? You listed what to do, but not which products to buy, would reduce the risk to buy bad stuff again, thanks in advance

Your issue could be the motherboard.
Absolutely those factory cables are garbage, we had two Leeco destroyed by bad cables in my house. Fortunately, they were under Amazon's warranty and they were replaced with new phones.
Currently I also have a critical issue also, where my phone will start in fastboot, but will shut down when attempting to boot to the system or recovery.
To make matters worse, I could only find used motherboards priced on the average of $150 which is way too high when you can find a complete X720 on Aliexpress for about the same price :
As far as getting your data, can you boot to fastboot, if so you may be able to copy the data from the phone and then erase storage using adb. For example, adb pull <path-of-the-file> or : adb pull sdcard/ ( this should work)
As far as the issue about you phone, something that you flashed may have damaged the board. Last week several people had damage as the result of flashing a Rom that didn't have thermals ( it was an accident / Oversight)
Another option, if you are like me and cash is tight. Xiaomi has several quality phones for around $200 and the specs are excellent. Phones such as the A2, Note 6 Pro, or check this out ( Then google Snapdragon 636 vs 821 )
I hope something here helps you.

Hi
Sorry for the late answer, but I was very busy in this week!
.
So You can buy the original board from Taobao but only through Yoybuy. You can buy lots of factory parts for the phone or any other gadgets as well of course. Just you have to use the taobao's item link.
Here you can find what I I bought. This is 100% original board!
https://item.taobao.com/item.htm?id=563268285618
It was only 14$+ 7$ was the yoybuy service fee. The shipping cost depends of the shipping version.
The whole shipping after my payment was about 2 weeks to hungary!
Good luck!

Yes of course it is quite simple, just you have to write it on TAOBAO 'X720 mother board' to the search bar.
I found a seller, he is selling more version of boards.. Just use this link at the Yoybuy and you can choose the right version at that site.. https://item.taobao.com/item.htm?spm=a230r.1.14.1.2f6347c1TLsAv7&id=572435958176&ns=1&abbucket=20#detail

While what this website is selling is hard to determine for an English speaker. What they are selling is board repair at a super low price. Frankly, I don't understand how they make money.
But here is an option for you. I too have an old phone with a fried board, so I will research this place further and probably will mail my board to them for repair.
https://item.taobao.com/item.htm?sp...GLVYx&scm=1007.13066.127260.0&id=559560190173
By the way, you have to create a account to view pricing and there is an option to change the site to whatever language you prefer. Basically with the cost of transport included it seems that we can have our motherboards repaired for under $20.

While what this website is selling is hard to determine for an English speaker. What they are selling is board repair at a super low price. Frankly, I don't understand how they make money.
But here is an option for you. I too have an old phone with a fried board, so I will research this place further and probably will mail my board to them for repair.

I have no idea, as I am not there with you and I don't know what steps you took to ground yourself prior to changing out the board, if you were sent the wrong board then you should contact TaoBao for a refund. They have a return policy similar to other large online vendors.
Is it possible, that you received the wrong board, or that you shorted out the board by accident? If it didn't look identical to the board that you replaced then it obviously would not be compatible. If the board was in fact a correct working board, your issue could be something else such as the usb card, the connection to the usb port, or shorted flex cables. ( I assume that you tried alternate usb cables?
To be clear the link I provided was intended for on site repair, not the sale of a motherboard for sale. (repairing the board that you already own)
For example, If you have broken solder connections, you would pay a small deposit and ship the the phone to the advertised repair shop, for them to repair, by fully reballing the board.
There have been users that were able to get their phones back in working order for under $40
Finally if you are hearing a buzzing noise then you have a burned capacitor which should be an easy and cheap fix for a shop that has the tools and can repair at the component level.
Edit
The price of these phones have recently dramatically dropped Here you can find a new 4GB/64GB X720 for $140
You can replace the usb board yourself. Hardest part is removing the screen. You need a heat gun for that. And double sided 3m tape to reattach.
The actual board only costs $5.
Amazing that a 400 phone will be rendered useless by a $5 part.
Hey guys it's me again, I didn't know what to do and the phone was just flying around collecting dust. But I found a seller that apparently stocks original USB Boards. The ones you could get so far were missing components that are required for OTG etc.

It's 13$ but well, better than a wrecked phone. Now I can also solder quite well, sad I threw away my original board otherwise I could have transplanted the missing IC circuitry. This wasn't a problem I thought that would happen. "Missing" components on a board never happend to me and "a**hat" move to sell boards without saying that it's only good for charging...
This is the part I bought off eBay.

The only soldering necessary was that it didn't come with the speaker so had to remove it from the old bad board and solder it to the new one.
Phone has been back to functional since. I had to replace battery as well because I think the heat gun damaged it. That was about $17

Is OTG working since the compontens of the product you send are also missing on the photo.
Did you want me to attach an otg adapter to my phone to see if it could access the storage?
Or did you want me to connect my phone to a computer via usb-c cable to see if it could be accessed by the computer?
FYI, here's pictures of the old board from my x727 for reference

Here's my comparison between an old Aliexpress board I ordered and the new one with all the necessary IC components on it. Quite the difference...
How much was the new board? Not knowing really if it would work or not, I just ordered the cheaper 5$ board.

Could you please share the link where you bought the genuine board from?
