[Q] thin vertical piece on the mainboard that leads to USB connection cracked - Verizon Samsung Galaxy Note II

Hello to anyone reading this,
This crack in the board happened after it went through the clothes washer, and it was gf's phone so i feel really horrible about it .
Anyways i have yet to even find out what this piece of the board is named. It's cracked in two places on the vertical part of the board that leads down
to where the usb connector is located (everything else appears looks ok just these two cracked pieces). I'm just looking for any help at all, hoping
someone might be able to offer any help at all, or if it's even possible to salvage. I have an uncle that is got a good amount of experience in
soldering/electrical stuff and can handle the soldering/fixing since im still a bit of a noob, but he was unsure about how to go about it since it would
require some very small wires to fix the connection traces, so if anyone can offer any advice or instruction on mending i would greatly appreciate and
can send some BTC for your help. I attached 2 images, and can supply more if you need more detail.

So far the only thing i can think of is to get a broken board and remove the part i need at the easiest location it could be re-attached... no clue if that easier area exists though..

Replacing the internal battery & screen?

My battery has gone to hell. After getting it down to 5% one day, it just would not hold a charge long. Then I got it down to 10% a week later, and it really got bad. Life is about 1/3 what it used to be. I also have some dust and even small hairs or flecks in the screen.
So...I ordered a new advance replacement unit from T-Mobile, and it just arrived. Simple enough? Well, I have the memory upgrade in mine, so I need to do some component swapping. What's the best way to go about this? What parts can be disconnected easily (or more importantly, reconnected)? Where is the damn battery (didn't see it in the disassembly photos on the site)?

Please specify 'component swapping' in more detail... Are you actually thinking about swapping the memory upgrade??? You do know that that would mean desoldering the 2 big memory chips on both boards, cleaning them and the boards, and soldering them back... How good are you at smd soldering??? We haven't dared doing that, yet... (some pics of upgrading memory of an iPaq are available at http://www.linearlogix.com/ipaq/upgradereview.html
There are commercial services doing the upgrade (32 -> 64 mb), if I were you I'd contact one of those.
Other than that, we're currently swapping lcd screens, touchpanels, mainboards from 3 broken units to create 2 working units and 1 very broken one. So, what do you need to know exactly?
BTW, the battery is stuck on the inside of the back cover.

No, no, I can solder normal stuff, but not that. I mean, I assume what I need to do is keep my own motherboard. I'd like the screen, case, and battery from the new unit. On the radio section, I suppose it doesn't matter either way. So I incorrectly said "component" when what I really meant was "board," and desired advice on doing that.

Ok, so you want to use the screen/touchpanel/backlight assembly from the new one (smart move, not taking that apart; besides the fact that it's glued together and you need to separate it on the correct separation, that also leaves the risk of forgetting the correct orientation of the glass panel with little dots on it, used to distribute the backlight evently onto the lcd; and, there are slightly different assemblies out there which need slightly different panels...). You should keep all boards from the old unit (old mainboard including old radio unit, use the new screen/touchpanel/backlight assemly, and the new case (which includes the new battery).
You could consider swapping IMEI numbers on the units... Although _shops_ never register the numbers when they give out units, service departments might. You know where to find the tool to do that...
The screwing around of the parts should not take more than half an hour if it's the first time you take apart this unit (but have taken apart small electronics before) and less if you've done it before.
Beware of the really thin clear plastic rings used under the screws to screw down the display...
We won't be publishing a very detailed 'how to swap your screen' instruction any time soon but do have some raw unedited pictures of the operation. I'll see if we can get them online any time soon.
Have fun,

I ended up doing the change and ran into a snag--the plastic pin that sticks out of the top power button was loose or broken (probably happened in one of the many drops the unit has experienced). When I opened the case, I lost that. Had to send it to PPC Techs to have them solder in a new power switch.
Other than that, disassembly is pretty easy and straightforward. You mentioned you won't publish a how-to...is that because of not wanting to have it on the site, or that nobody wants to write one? If the latter, I'd be happy to write it up and include my detailed pics.
If you want to make a detailed howto on how to open and close the unit, and how to exchange certain parts, we will gladly put it on!
Do make sure to stress that people need a certain level of experience or be willing to risk losing the device though...

That, my friend, is the mother board.......
Tbh......attempting to solder it is likely to cause more problems than it solves.....
Your best option would be to forget about attempting the repair and go and look for a 'donor' phone....that is to say, a phone with a broken screen but otherwise intact....most online auction sites should have some.....other than that, bite the bullet, and send it to Samsung for repair.....

Even if you did manage to do a successful repair, these phones don't like being immersed in water even briefly, so the fact that it has gone through a wash cycle (?) is likely to have caused issues due to water penetration and short circuiting.........

Tyvm for your reply, and about the board replacing, what if i got a broken board that still had the vertical side intact could there be a location where i could remove it where it would be much easier job of reattaching to my motherboard? And i also just realize i posted in the wrong forum this is a verizon GT-7100
ANY repair using a heated soldering iron has the potential to cause further damage. Unless your uncle is an experienced electronics worker, I'd advise NOT to attempt it.....
These boards are built by computer controlled robots that don't suffer with shaky hands, can easily manipulate REALLY fine tipped soldering equipment, and know EXACTLY how long they can leave the heat applied without causing damage. With the greatest of respect, your uncle ain't one of these robots......he's human, and we ALL make mistakes......

ok, i found a pretty cheap deal on a board that's actually same exact one my phone has says good esn and working they claim, but it comes barebones meaning i'd need to simply swap the vibrator,cam, usb ribbon, etc with the ones i have already. what i'm worried about is if any of these components are highly susceptible to water damage and might need to get them as well
Mate....water damage *can* be an endless, bottomless money pit......
You might be lucky in that replacing the board *appears* to fix it.....but over time, other components may start to build up oxides, or to corrode away....and it's fair to say that any components that were short circuited by the initial immersion will have had their operating lives significantly shortened.........
The choice is yours, but I'd keep in mind that it *may* not all be 'plain sailing' in the phones future.......

[Q] screen wanted please

I'm not sure if this is the right place to ask folks and if not I apologise in advance.
I am after a replacement LCD for my SGS 3. Unfortunately my new puppy bit my phone and cracked the front glass. So I bought a new glass and as I was trying to get the broken one off the puppy jumped up at me to play....knocking my arm and straight into the LCD. I have stripped the phone down completely and scraped the old screen off but I need a new / second hand one if anyone has one they will sell me or knows where to get one from.
I dont or to be honest cant afford to spend a lot of money as due to disability I am not working at the moment. I have some important files on my phone that I need to get off but im not sure if the motherboard has been damaged...when the phone is plugged into the PC all I see is a red light constantly
If anyone can help me I would be extremely gratefull

Broken screen. Is there any repair guide?

Hi guys,
I accidentally sat on my Z3 Tablet (I know how that sounds, but I had it in a messenger bag - not used to carrying those - got on the bus, sat down and there it was right where it was not supposed to be) and now I got a nice case of cracked screen.
As far as I can tell only the glass is broken because the screen and digitizer still work fine and with any clue how it is built inside I am definitely capable of fixing this/replacing the glass/screen as a whole. But after looking for a while, I haven't found any teardowns/fix guides etc. Because I am reluctant to do this "blindly" (although this would be my final choice) I wanted to ask if any of you has seen something that could help me or maybe even had the same problem and fixed it?
This is my first post and usually I only read in this forum, so I want to thank all of you who participate here for the massive amount of useful information
I also have been looking for teardown instructions and found nothing so far...(Not that i have something broken, just curious what's inside )

So basically...I need an S6 Edge motherboard and I can't find any.

Disclaimer: I am new to this forum and I realize this may not be the right place for this post, but I know there are a lot of cool people on here so here goes anyway:
Okay so here's the story: A friend gave me a water damaged Galaxy S6 Edge and tried his best to revive it beforehand (soaked it in 99% alcohol, etc). It was exposed to water and afterwards the display went south...or so we thought. I bought a replacement used display and installed it, but it did not fix the problem. The logic board is the only thing I haven't replaced yet, and it has signs of corrosion, so I believe it's the culprit. Weirdly enough the phone still boots, charges, makes noises and can receive calls presumably...just no display.
I went on eBay and other sites trying to find any motherboard at all for the phone, but I couldn't find any in my price range (only 2 listings I found were like $300). Does anyone know where I can get one? I don't care if the IMEI is bad, etc; I just want the phone to work again. I'd like to keep it under the $120-150 range. I already have about $125 into this phone so I don't want to spend a lot more.
If anyone can help me out that would be great.
I have broken my S6 twice (it's not a bad phone, I had a lot of bad luck). And the second time the phone went total loss. The repair guy explained to me the S6 Edge doesn't really have a normal frame, since most of the things are actually glued to the screen. Repairing it, will be extremely hard. I know this is not a direct answer to your problem, but please be sure you know what you're going to do, before dropping a couple of hundred dollars on a motherboard.
Thanks but I know what I'm doing, haha. And no, the only glue inside the whole phone is the back glass and battery. Everything else is held in by connectors or screws.
