How to replace the data port

Hey guys-- got back from the t-mobile store and they told me the data port is dead (from water damage). It turns on with a fresh battery fine, but apparently I'm getting an error code. That code is probably that the data port is messed up because I can't charge my battery. I'm assuming I have to replace it. Does anyone know of a video tutorial or something that will show me how to do it?
thanks.

the chances of the data port being physically damaged by water is very slim- I think they are trying to tell you the circuitry is faulty. If you had ripped the charger out and bent or broke the port, then I could see it- but water cannot bend or break that way and corrosion is unlikely unless its been sitting a while.
Back to the original subject though, I just replaced a faulty USB port on my friends Moto Q. It wasnt bad, but you need a very small pencil iron (I use a station) and good eyes, otherwise you will bridge the tiny connections and be fubar'd.

Where did you find the port to replace it with...

find a bricked one on ebay or something..or someone selling one with a cracked screen etc...use it for parts

welp, i've never soldered... guess you gotta learn sometime. ports are bout 25 bucks... Guess I have a new hobby. Or maybe I should just buy an external battery charger... soldering sounds more fun though. Yeah, what i meant by getting an error code is when i plug in the charging cord into the cell phone, I get a red light instead of yellow/orange. But, I have to push up on the cable where i insert it into the port to get anything. So, its not dead, but either dying or drunk....... drunk from oil.... which it swam in... and got sick from. vegetable oil, not motor oil... which would be a waste of oil. Anyways, thanks for the replies and if you stumble upon a vid for the dash, please post it. I found some on blackberries, but not an excaliber.

sorry browser problem (double posted)

my friend sourced his usb port from Mouser (P/N 538-67503-1020) for $1.12 each. I still have one (he got a spare) but I dont have a dash to take apart and compare the pins. I assume they are all the same generic port, but the pin spacing could differ

that's pretty sweet speed. I bookmarked that webpage (dunno why really). I could just always link from here; but anyway, I received a new battery that I ordered before the geniouses at t-mobile told me that a red light is an error code, my old battery is perfectly fine, my data port is broken, and no... a new battery won't fix it. *** what's my point you ask?***
They don't know jack fecal matter. I just popped in the new battery and 1) my phone turned on, 2) my charging light turned orange, 3) my plug doesn't need adjusting to charge the phone, and just now 4) my phone has signaled to my through a pretty green light that the new battery just finished charging.
So, to recap, the guys at t-mobile said my port was fried and that all my problems were due to that. My theory was that oil (and come to find out water) damage caused the battery to malfunction and thereby refused to allow a current to charge it resulting in the errors. Turns out, I was right.
Thanks speed and all for your replies. If I need a cheap miniusb port in the future, I now have a good source. Now, Anyone know if a new lcd will fix the splotchy marks on my screen (look like dark puddle spots). I'll post a pic in a new post in a minute.

Yah you can grab a new LCD off ebay (fairly cheap) and then go to youtube and youtube "fix dash screen" and there is a tutorial on there that will guide you on replacing your screen.

just make sure its the lcd thats the problem- the outer clear part that you can touch is separate, and comes with the case. Mine are scratched to hell on both my Dash's but I refuse to buy new cases to fix them

i dunno what's up anymore
I don't know what to think of this thing anymore. This morning it wouldn't turn on, even though I had the green light on the device as it was plugged in all night. So, I kept fiddling with it hoping it would turn on so I could have ATT do a remote hard reset. Well... it wouldn't cooperate. So, I left it alone. Then this evening I was about ready to bury it and I tried the power button one last time and it turned on. But, the battery was really low and I got the red light again when I plugged it in. I guess the battery got a bit of a charge in itself just sitting there. So, perhaps the t-mobile guys do know what they're talking about. Well... i did actually get the orange light while it was on for that sweet minute, which should mean its charging, but I guess its not actually charging the battery. I suppose the last way to go is external charger. I'll probably pick one up off ebay for 15 bucks.

Electric charge in the case while charging

Hi all,
I put my desire onto charge and as I picked it up and touched the outer casing I could feel this electric charge vibration on my skin, you can clearly feel it as you run your finger along the side of the metal part of the case.
What I want to know is.. Is this normal for this kind of phone or I have a dodgy one where something is touching something it's not supposed to be?
I had a laptop once that did the same, It had a metal lid.. A portege 3110 years ago and I assumed it was faulty.

I have the same thing, more so on the left side. Thought maybe everyone had it, be weird if they dont

It's perfectly normal. I would have thought that having a laptop that does the same would have confirmed that.

Yeh I have the same, it's perfectly fine
Even my iPod Classic does the same, had it for 3 years and it's still going strong.
But yeh I wouldn't worry about it, tbh I get turned on from the electric charge from my BEAST

I am super sensitive to things like this, It actualy makes it difficult for me to use the device while plugged into the charger. I stuck my multi meter on it to check and I get a high reading from the outer part of the case that surrounds the screen, even with the phone off charge and just sitting on the table I can get a decent reading.. Is there a design fault with this phone that's causing it to leak charge into the case?
I've checked my old N95, O2 Zest & Moto Droid for the same issue, I thought the droid would be the same since it has metal casing too but it's not.
Are you 100% sure this is normal? And what are the side effects of being continualy pumped with current while using your phone plugged in?

no, you should not be getting charge in the case....it does sound to me like you have a problem.
Mine has no such feeling when charging.
I can't imagine there's any dodgy side effects, it's only 5v at 1A. that's less than sticking a 9v battery on your tongue, but it's still not right i don;t think.
If you do send it back to HTC, get someone to take a picture of you and the multi-meter clearly showing the charge on the case. it's just an extra bit of evidence in your favour.

I don't have any such problems.

For those of you that can not feel this, try the following.
When the device is being charged, very lightly run your finger along the "metel" edge part of the screen.
Its the same effect that i have when in bed with an electric blanket on and i lightly touch the brick wall!
On another note, there is no "tingle" when charging from from a pc.

Same problem here.
When i charge it on my Acer laptop with Windows or Linux, everything is ok. Today i connected it to my EEEPC with Linux on it, and after the battery was approx. 90% charged again, it started to "wobble" when you touched it. Maybe it was there before, dunno ...
I can feel it on the screen and on the bezel. If i hold the phone with 2 hands, i can't feel it. And yes, i'm very sensitive to electrical currents
I don't think it's "fine" ...

I have the same problem, just assumed it was a faulty charger as my sisters charger, and my car charger don't replicate it.

Charging Issue

Hi guys,
i have some issues with charging my inc2.
it is not accepting any charge anymore, tried diffrent chargers, cables, even on my pc but nothing. The orange charging LED just flashes slowly on and off...
Any ideas?

Need to replace phone or replace charging port.

Yes, unfortunately it is a known hardware issue. Over time, the charging port starts coming loose. Like mentioned above, you CAN fix it yourself. There are video tutorials on YouTube and the replacement part can be had for under $10. If your device is still under warranty, Verizon will replace the phone. If it's not under warranty (or if you just want to give it a go), the port replacement process is pretty straightforward.

I might give it a try. Does anybody have a video or a link?
The weird thing is, that the battery is discharging very fast, could it be just a bad battery?

Could b the back door on your inc 2. I believe you need the back door on to charge cuz it goes thru contacts on the back. I dropped mine one day and charging and getting signal was almost impossible till I figured that out and bought a new one

Ok.
Seems to charge now. Won't touch it until it is full. After that I will check what is going on.
I don't know where this issue came from.never dropped it nothing. It was even in a Otterbox

The issue stems from regular use. The charging port is essentially held in place only by the connections to the board. Repeatedly plugging and unplugging the power cable causes it to break over time.

actually just replaced the charger port on my incredible 2 today. It really wasn't that difficult at all. If you have any questions feel free to PM me

yeah it has to be replaced. happened to me last month. It's honestly like the worst flaw with this phone

Def need to replace it. Same issues I was having at one point with it randomly taking charge. I found that if the charger is plugged in a held a certain level ( i placed the phone on a flat surface with a book under the cord for leverage) it would charge just fine.
If you are rooted and sending back, make sure you revert to stock to avoid any annoyances.

I've managed to solve this issue without messing around with the phone's innards (the last time I did it was a disaster and I was forced to buy an entirely new phone). It's not pretty, but if you twist a rubber band around the micro usb end of your charger, plug your phone in, twist that same rubber band around the phone itself, and make sure the connection very tight, you might get some more life out of your charger port.
Ugh. I can't wait for my upgrade.

Nice name there Dave.

While, I give you major kudos points for MacGuyver-ing a solution, that's more of a quick band-aid than a real fix. I could imagine having a rubber band around the phone could potentially hinder usage.
But hey, way to think outside the box! :good:

Thank you. You're telling me. Do you know how hard it is to use a touch screen with a rubber band across it? Oy.
Right. The caveat here, of course, is that this technique will only help charge your phone until the charging port becomes so disconnected from the board that no amount of force will reestablish this contact. And this will inevitably happen because you're going to keep plugging and unplugging your phone from the charger which is what created the issue in the first place.
If you know you have big, sweaty, idiot hands (like me) that are going to destroy your phone if you take it apart (like me) and you can tough it out: more power to you. The other alternative is to buy an external battery charger and a second battery. The disadvantages here are pretty obvious (e.g. you have to carry a second battery around; if you forget a second battery, you can't ask another Android user to borrow their phone charger, etc.).

Overheating when used as navigation?

I realize this is a worse case scenario, but i used my phone as navigation for the first time today and after maybe 20 minutes of having it on my dash, charging, listeing to bluetooth music while navigating it quit charging and the red notification light started blinking. I had power saver on with the screen at its lowest Automatic Brightness set. I know this is a stress test for it, but lots of other phones I've had didnt have a problem like this. I dont use it as navigation too often, but it cant not charge if i do use it that way.
Anyone elses do this too?

Mine starts to get pretty hot with the basics....browsing..youtube...charging while not using. It's not happening all the time but it gets frustrating. This is my second m8 ( I returned my first for heat issues) so it's happened on both non-rooted m8s.

I went back to the tmobile i bought it from, they hooked it up to a laptop and ran a few tests on it and declared it fine. They said to call corporate tmobile tomorrow (since they took the holiday off today) and tell them whats going on and they can put it in my notes to have the store replace my phone tomorrow.

Anyone else's phone do this? I ask because corporate gave the store the OK to exchange my phone, and if this is a problem with all M8's, theres no point to exchange it.

I am debating on getting a different phone all together. I flashed a few Roms.... Still having the heat issue.

So I was able to trade my phone for a new one at the store,...I'm now past the 14 day trial, so I hope this one is OK.

Are you guys sure it gets that hot? This is the same thing with the M7 and people were saying the same thing. It's thermal conductivity which you guys are feeling. Keep in mind just because your other phones don't feel as hot doesn't mean it's not the same temperature. Here's a video about what happens and how people confuse themselves. The M7 and M8 are different and the M8 should conduct more heat due to it being more metal.
https://www.youtube.com/watch?v=vqDbMEdLiCs

Although yes, it's hot to the touch, I'm talking about the battery getting so hot it quits charging , the Orange led blinks, and the battery starts going backwards even though it's plugged in to the car charger.

That's why I was making sure if it isn't merely it feels hot, and not actually being hot.
Are you using a 1.5 amp or something higher? I notice when I use large amp charger it'll get hotter than usual, but it does charge quicker.

It's a Verizon generic car charger, 1 amp. I'll be using the replacement phone tomorrow afternoon for navigation, I'll report back if it's any better with it.

I Just found a 2.4 amp Rocmetfish charger that gets good write ups at best buy. Wonder if that would help.....2.4a is a lot more than 1a.

Question Z Fold 3 'Too Cold To Charge' after water damage

Okay, hello XDA Forums peoples! Ive been lurking here for like a decade. I feel bad for bothering you nice people, but now I'm at my wits end with this phone.
Okay, so, long story short:
Z Fold 3, let it run the One U.I. 4 update, bricked the whole phone, wouldnt come back on. This happens a week away from being out of warranty. So i get samsung to agree to let Asurion/uBreakiFix repair it (I almost always fix my own electronics, I hate Asurion, I've had problems dealing with them before, but its free so whatever). Well they get it working, i asked what they did and they were basically like 'uhhh idk'. I assume it was just an 'unplug the battery and plug it back in' kind of thing.
Anyways fast forward to a couple months ago. Im walking along the creek, i always keep my phone in my backpack for safety. Zipper on my backpack comes open some, phone falls out and directly into the water for about 3-5 seconds. Goes black within 15 minutes. Alright, so it seems like maybe the boys who worked on this didnt seal it back properly. Whatever.
I let it dry for about 4 or 5 days. Comes back on, everything works except the front screen's digitizer(which is cool for me, because the inside screen still works fine) and its reporting too cold to charge, so now once the battery runs out i have a new foldable brick! Yay! I check the battery temperature thats reported in settings and its completely fine. I hit it with a hair dryer for like 5 minutes to try and trip the thermometer, and nothing happens.
I tried some cheap shots in the dark, i replace the USB charging board, i replace the wireless charging coil, both of which have thermistors on other older samsung phones, so i figured it was a decent guess. Still too cold to charge.
So I find a schematic, or not exactly a schematic, but like a boardview, i guess. So at least i know where the thermistors are to check them. Theres about 10 thermistors on the main and sub boards. 5 of which are covered by metal shielding which i am just terrified of trying to remove, mainly because i havent done it before. So i check the other half.
The thermistors used in these phones are like inverse, so they have less resistance for higher temps and more resistance for lower temps. If one of them is dead, it will have like "maximum resistance", right? Which would report the coldest possible temperature, right? So that all makes sense, to me at least.
The 5 i can get to with my meter to check, they seem to work completely fine. From what research ive done they seem to be like 100k resistors when measured at ~70 degrees f, and i can watch the resistance go up and down when its cooled or heated past that temperature. Okay, perfect. That all checks out.
Because the other ones are under some metal shielding, i assume theyre most likely fine because any water would have a harder time getting in there. So i skip to the most expensive option so far: i buy two replacement batteries. The schematics do not include the battery, so i dont know where the thermistors are on my current batteries to check them, if that was the problem.
Well, batteries came yesterday, i pop them in, still too cold to charge. I've already ran the phone dead checking it, so i cant do any further diagnostics with the phone on. And now the most i get is a Yield sign with a thermometer in it when i plug it in.
Okay, so... Idk?? This problem is starting to get over my head. What do y'all think? It seems like my options are becoming more limited and expensive.
I can try and put a big blob of solder on the top of the shielding and pull it off to check the remaining thermistors, which seems to be how people remove those things. I also have have hot air at my disposal, which is always risky with tiny things because too high airspeed might blow components away on the board and then i'll probably cry.
It could just be a connector somewhere on some flex cable? Maybe? I mean like maybe what if one of them is for reporting temperature, and water corrosion is stopping it from sending a signal through???
Im fine with doing whatever, but i just want a charged battery first so i can recover my data before i do anything that drastic. I mean, back in the day they had 4 big pads on a removable battery. You could buy a universal samsung battery charger or rig a USB cable to charge it, but I have literally no idea what to do here. Does anyone know of some specialized battery charger that will connect to these flex cables?? That would be a gigantic help right now. Or if i knew where to get a Z Fold 3 just to pop it open and charge my battery with? Or maybe just sit there for 2 hours holding two wires to the positive and negative pins?!??!?? I dont know. Someone throw ideas at me, please!

Might be worth buying a bench power supply and either injecting voltage through the phone or connecting it to the cells to trickle charge them back up? Im not an expert it these just throwing ideas
