My 8525 mini usb connector broke(pics included)

hello, i have had an 8525 since december and it has been great. except the other day i was going to charge my phone but i saw that the connector was messed up, and i have no idea how it got that way cuz my phone has zero scratches and hasn't been dropped. i tried using a 2mm flathead to fix it but it didn't work and i was scared to use a lot of force because i don't want to cause anymore damage. any help would be appreciated, thanks.

thanks for the reply, and yes the phone still functions perfectly. i turned it off though so i can save it for an emergency, as i do not have a backup phone.

Above we can see:
1
The rear view of the USB connector
2
That re-soldering will not be possible. This is a multi-layer board and these components are not part of or soldered to the USB Connector.
Above we can see:
1
The top of the USB housing and it's anchoring (possibly earthing also) soldering.
2
Soldering would be possible here to re-do the anchoring solder joints. This would be worthwhile if the connections are still in tact and the purpose is merely to re-anchor the housing.
Another view above of one of the anchor joints. Caution should be used not to dissipate excessive heat through the board - given its multi-layer nature and components on the reverse side.
Mike
EDIT:
In baller4ever85's picture it looks like one side only has come adrift and it may just require the anchoring joint to be re-soldered - but that assumes the contacts are still fine otherwise.

^thanks for the detailed pics. i don't have any experience with soldering. will htc repair it? my phone is also still under warranty w/at&t so i will see what they can do(probably not much).

I had this problem to the point I could not Sych or power the phone. I called at&t and it was replaced under warranty repair. It was replaced with an at&t branded 8525.
In the FWIW department... I did call HTC prior to calling at&t. Since this is a mother board repair item, minimum charge to look at the phone was quoted as $245!!! Thus the call to at&t.

If you can't get it fixed, I'll buy it.

well i called at&t and they said i could do a warrnaty exchange but the rep told me i would most likely be charged $500
so i guess im not sure what to do.

That must be because they replace the entire board. A bit different from here:

Possible to transplant the radio from the Hero to the Evo making it 3G-only?

This is a question for those familiar with the innards of the HTC phones.
Do you think it would be possible to put a Hero's radio inside of an Evo, thus making a 3G-only "Hevo" that has the horsepower of an Evo but the 3G-only radio of a Hero?
Obviously, this would take some expertise -- perhaps some work with a reflow machine or something of that nature to actually move the tiny chip -- but is there one single chip that could be physically swapped which would essentially change the ESN on a phone?
If the chip was physically swapped, would this have any chance of working from a technical standpoint? Could an Evo function if it had the radio of a Hero? If not with a stock ROM, perhaps with a third-party ROM?
Thoughts?

To what end? How is that different than just turning off 4g?

I have no idea but I just wanted to ask.... why? I don't think this one deserves an answer of "because we can" either.

With enough money I'm sure anything is possible but you have programming that might correlate with or to that radio. Just like the issue with HTC putting a different camera in the Evo is causing some problems. Imaging swapping a radio what kind of problems you would encounter. Sounds like a major pain the the a$$ with a huge probability that it would not work. Not to mention that is one reason the Evo is the $h1t because it has 4G.

i think the answer is NO. sounds to me that someone doesn't want to to pay for 4g service. i agree the extra $10 sucks because where i live i don't have 4g. but im not going to frakenstein my evo either.

Different chips with different pinouts... Never happen.

my favorite quote

To me it sounds like the OP wants to move the radio chip from his Hero so that he can sort of clone his Hero's ESN. I'm no expert on the subject, but I think a standard cloning procedure would be a lot easier.
FWIW, the chip on the Evo's motherboard that handles 4G/WIMAX is separate from the 3G radio chip. It's the Sequans SQN1210. I suppose if you're really that desperate to get away from the $10/month "4G fee" (that's not really just for 4G) then you could desolder it from the motherboard and then take it up to a Sprint store and see if you can get them to remove your premium data fee from your monthly bill. While you're at the store, ask for the 10% S.T.U.P.I.D. discount.
P.S. the 3G radio in the Evo is actually included in the QSD8650 chip. Yes, this chip includes the main CPU, GPU, CDMA radio, and even a GSM radio. To do this swap, you'll need to use a lot of extra solder.

Am i the only one thats thinking there is something amiss with this question? i can't imagine any LEGAL reason someone would want to swap chips out with an old phone.

Yup, he either found, stole, or bought a flagged EVO and is trying to use it.

There are much easier ways to clone an ESN than swapping chips.

Korean Galaxy S II has NFC!!! *pics*

Just got my hand on a Korean Samsung Galaxy S II. Found a NFC option under Setting menu. Then i removed the back cover, and found the NFC logo on the battery??!!? Could it be the battery is where the NFC tag is at?

What do you guys think?

Interesting
This is super interesting! From your pics I see that the phone has 4 connector pins, how many does the battery have? How many does the Indian battery have? I am inclined to believe this is the mystery behind "Optional NFC".

It would be interesting to see some side on shots compared to a standard SGS II - I hear the NFC version is somewhat thicker?

AFAIK, the KOREAN SGS2 had NFC since launch. lol

sd card slots not in the same place either

An NFC-chip inside the battery would actually make sense. It has a large surface area inside the phone, which would make the NFC handling easier.
However, the design is completly different. On the non-NFC GS2, the microSD cardslot is on the left side and the battery connectors are on the right side. Some small differences with the SIMcardslot and the external antenna connector too. So it seems its more than just the battery.

What are the specs on this version? Do they use the AT&T US frequencies?

Just a quick question: Have you checked 3G bands on the phone?
I heard that the Korean version is NOT quad-band, and am just wondering if you could check that.
Thanks.

I mentioned this a while ago.
http://forum.xda-developers.com/showthread.php?p=13760704#post13760704
It's my understanding that the phone extends the NFC antenna onto the battery so signals don't get blocked by the battery.
It's tri-band only. Don't know why they'd do that though.

I think this version is quad-band GSM and quad-band UMTS. Not sure, I dont have the box with me. Will test this with AT&T in the states when i get back there next month.

How do you check to see if it's tri-band or quad-band GSM/UMTS?

can you pls dump the stock ROM u have in that SGS2 ? it might be useful... i dont know in what way, but may be yes or may be no...
just curious.... from that pic its quite clear that the battery has the NFC chip built in to the SGS2..... thats amazing...
thats why samsung has maded such a thin plastic backcover... i guess so.... nice thinking & it is an indirect clue i am almost sure....
what do u guys think ???

Was on one of the Korean Samsung Spec pages. Lost the link. Although I don't see why they'd make the international version quad band and the domestic version tri band, makes no sense. There's a number code you can enter to check the phone's settings/hardware. It didn't seem to work for me though.
BTW how did you manage to get the phone? It's my understanding you can't buy it outright here unless you're on a visa. Unless you're on a visa...
@manuvaidya:
They've been dumped already. They were dumped a few days after the phone was released. Seems like it's just not that interesting to devs here.

I hope so, we can just purchase the battery and/or sim if both are needed and we get NFC.
I guess NFC in the future release might mean it comes with a NFC enabled battery.

I found a basic side-by-side comparison of the Korean and Internation models:

The UK release phone also has 4 connectors pins and the UK battery also has 4 connectors.

I have the same battery that is labeled "Near Field Communication" and no, unfortunately it does not enable NFC on a stock UK phone running KE7.
Also, did anyone notice that the connector pins on the Korean SGSII are on the left side vs ours which is on the right?

I think it's like that because the Korean SGS2 has an antenna on the right side to watch TV-over-the-air.

Extra thickness is probably from the DMB tuner
All korean phones come with DMB tuners.

what is the software version of this device?

Dang, I was thinking of getting a spare battery from Korea.

Do both batteries work with uk version of the phone?

[Q]Data connectivity issues, 4G drops after opening Note 3 to clean prox sensor

Hey guys, I am not totally sure what I did but may I can get some opinions.
I am on a n900v, rooted, on build 4 (4.3) of JellyBeans. Ive also verified that I am on LTE/CDMA
I was having some issues with the proximity sensor so I followed a detailed tutorial on youtube on unscrewing the back and airdusting the sensor. Im pretty handy with electronics so I was pretty cautious and careful.
After reassembling it I am not having issues with 4G dropping out to 3G and or high ping/lag. The phone on idle will be show LTE 3-4 bars. At times when I try to use it for data purposes, browse the internet, download something, the connection will drop out down to 3G.
Downloads and uploads seem really slow, often at times they dont even complete (dropbox progress bar freezes). Speed test often has high ping, and while testing, I tend to get network communication issues. My speeds are pretty rough as well.
Ive opened it back up, nothing is loose, nothing damaged, antenna pins all seem fine to be making fine connects from the board to the backplate.
It almost feels like I am being throttled, but the dropping down to the 3G and the connectivity issues makes me want to rule out that.
Im just curious if you guys have any ideas on how to handle it.
A couple of things I have considered. 1. Calling in for a replacement SIM card (its still the card I had from GNex launch day, maybe taking it out somehow has it acting up? 2. It is out of warranty, though I do have asurion, though I had considered canceling it. I could report it damaged and file a claim (though I could get stuck with a 4.4.4 device in return).
Any other options I haven't considered would be appreciated it. I thought about reflashing the rom but this seems more likely hardware based than software.
Thanks guys!

No ideas guys?
I swapped SIM cards, its still happening. Not sure what my options are other than swapping out the motherboard, but a warranty replacement is probably cheaper.

You already covered the thing I thought it was also I fixed my sensor by editing the calibration for it.

Yes it does sound like the 4G antenna is broken or unplugged. But you said you checked that and wires were fine. So NK1 radio only.

Appreciate it, Ill take a look later on when I have some time. Thing is, I never even took off the motherboard or anything but the backplate. Most of the antennas are just contact points to the backplate if I am not mistaken?
Also, even when on 3G I seem to be getting a 4G signal. See the screenshot. But its like the handshake between 3 and 4G is messed up.
Though that LTE CQI value being n/a could be an issue.

No...that's normal (cqi being n/a)
The screws around the backplate are what "attach" the antennas. There have been several reported instances of signifigantly better reception after making sure those screws are "snug."

Help finding correct charge port daughter board for Galaxy s5 G900W8

My charge port is busted and I want to replace it but cannot find G900W8 (Canadian model) anywhere.
I read somewhere that I could use the G900T model daughter board.
Can anyone confirm this? Thanks!

you can buy any charge port of any model, it is default from manufacture. ------- Galaxy S5 SM-G900F works aswell like i said.
you can't buy the charger port of Galaxy S5 New Edition because i believe it has different mAh and it has some pieces that does not have on S5 Old edition.

My model is the Canadian version Galaxy S5 - so you're saying I'd be fine no matter what version of the daughter board I buy?
A second question - I've noticed online you can buy just the silver micro-usb port... Would this be an easy fix? Does the port itself pop on and off the motherboard? Or is it hardwired / requiring lots of intricate soldering? If it pops on and off just like the flex cables do onto existing pins, then that seems like a much better solution - but I can't tell without taking the whole thing apart and no one discusses this as an option online - they all talk about replacing the daughter board.

No.....it won't be fine.....this is something I know about....having had experience of this issue on a number of Samsung devices.....
You *do* need to match the board physically.....but not only that, you need to match the REV (revision) number from your existing board to the one you buy....
There will likely be a number of older/newer versions of the board, and in my experience they are NOT interchangeable.....
And as for replacing just the socket, this is something I have considered attempting in the past....but the simple truth is that the connectors are just too small to accurately hand solder....You'd need a very low power soldering iron with a needle point tip and a rock steady hand.
You'd also need a lighted magnifying glass to enable you to actually see what you were doing.

in fact i believe they are default.
only matching the revision number. if you find an recent revision, that's fine. only not buying an old revision.
only what changes is the modem country code.

to change the usb port, you will need an soldering iron; 30w will be enough to do the work.
and experience how to solder.

It's saying that Canadians (G900W8) should use the T version. That's what I'm hoping to confirm. Because I cannot find the G900W8 version online anywhere.

@DBlackFireD There is simply no way of accurately soldering these contacts.....
I have all the practical hand soldering experience you can think of.....it can't be done.....There is a reason that these boards are assembled on automated production lines, and that is that computer controlled robots do not have shaky hands. If you try to hand solder the socket, you WILL end up causing other damage.
@scott487 I understand that the W8 board may be hard to find.....it might well be the case that the board for the T variant is compatible....I had a look at the thread you linked to, and I noticed the lack of feedback as to whether it worked or not...
If it were me, I'd still try to source the W8 board, and keep the T board in mind as a last resort.
With regards to what has been said about the REV versions of replacement boards.....
There may be some truth about newer replacements being reverse compatible with older originals....but doing things the other way around *definitely will not* work.....
And getting the wrong REV version has been known to break functionality on other Samsung phones.......things like data transfer, signal strength etc; so these boards are NOT generic/default....
I still maintain that replacing your existing board with one that has an identical REV number should be considered as a first resort......
