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
http://www.mouser.com/Search/ProductDetail.aspx?qs=7zcQ9RRVJlhHWuXYKEhKMg==
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.

Since this morning my phone says it's charging when in fact it's unplugged. I tried cleaning the charging port, wiping cache, full wiping and reinstalling the rom, everything and don't understand why it'll never get off charging state.
I do check in settings while unplugged it says not charging and when plugged in says charging, but it's stuck saying "on battery for 23 min" and the icon never stops from charging....
Any suggestions? It's really annoying... Never had a single problem with my One S...
SOLUTION: Clean the charger port with a hard pointed object (that's what she said), make sure you clean and dirt or particles from underneath the middle piece in the charger port.
Also, if you notice the middle piece is too close or making contact with the bottom, use the pointed object to CAREFULLY bend it up a little.
Do all this while the phone is off and battery out. Use compressed air if available. if you wet it then completely dry it before putting the battery back in.
did you try wiping the Dalvik cache when you did the regular cache?

something like this happened to me about 2weeks ago.
It would say saying/ disconnected none stop.. if i didnt notice it would of burned my screen.
I just turned the phone off and removed the battery

A LOT of users have reported this problem, yet Samsung claims it is water damage and won't do a warranty repair: http://www.reddit.com/r/GalaxyNexus/comments/tqlii/samsung_refusing_to_honor_warranty_for_infamous/
There is already a thread on this which has some useful info:
http://forum.xda-developers.com/showthread.php?t=1427539It ranges from yep your charging port is f*cked or it just needs a clean and little tweak.
To get mine fixed I gave it blast with compressed air and a little needle to make sure all the lint/gunk was out of the port. I made sure the port was straight (if it looks like it is bent downwards slightly, try and pop it back up softly). Then what fixed it for me is to hit it with a little electrical contact cleaner.
I have a feeling the port was getting shorted by something as each of the pins on the microusb port are very close.
Hope that helps
Interesting - I'll have to keep an eye out for something like this on my phone.
I guess first step is the compressed air blast with a needle cleaning of the port. If that doesn't work then on to Samsung to see if they'll honor a warranty repair (outlook not good on this - apparently they claim water damage). Worst case you can get a replacement OEM charging cable off ebay:
http://www.ebay.com/itm/OEM-Charge-...440?pt=LH_DefaultDomain_0&hash=item33746d1eb8
And fix the faulty part yourself or have someone you trust do it.
[EDIT] here's a link to ifixit for step by step instructions on how to take your phone apart http://www.ifixit.com/Teardown/Samsung-Galaxy-Nexus-Teardown/7182/1#.T7pzI8XdOII
Thanks to all the suggestions, it does the same thing even after wiping, installing other roms or going back to stock. I tried cleaning it with a toothbrush but will try with a toothpick or something stronger. Will give updates once I do.
I would suggest the electrical contact cleaner is going to be a good bet too. If it is water damage, it could just be a bit of water has gotten in there (from a table, rain etc) and then when its dried impurities could be shorting the plug.
I am not sure what stores in the states have it (maybe bestbuy?), but we have an electronic store here called Jaycar which sells it. You could even just slip in and give it a quick spray in the isle.
Turn the phone off before doing it, and make sure it is ECC!
Fixed! It was the charger port. All i did was clean it out with a metal pointed object. I also noticed the middle piece was touching the bottom edge. It could've been making false contact. So i bent it up just a little and voila problem solved.
Hopefully this thread may further serve as future reference. Thanks everyone for your help!

I know I don't have a Galaxy Nexus, but the Nexus S can also suffer from the same problem. I believe it's because of the USB ports that are the same.
Inside the USB port of the phone there is a flat plate which slides into the wall charger/USB cable, I've noticed that when this is "bent" down it will show that it's charging when it isn't, so all you need to do is to find something (I used the tip of the missus'one plastic nail file) to "bend" it up about a millimetre or two and all should be fine.
Worked for me, so I thought I would try to help out here because I know how infuriating it can be.
I had this problem a couple of weeks ago. I also had issues with being unable to connect my phone to a computer. I contacted Samsung, explained my issue and they sent me packaging to send it away. It took me 45 mins to get the computer to recognise my phone to return it to stock, but i managed it. I then wrote a nice little letter explaining the issue, that others also had the issue and that I recommended changing the whole charging board.
I got it back a week later and lo and behold, they'd taken my advice and fitted a new charging board. Now it might just be me, but the inside of the micro USB port looks slightly different. I just can't put my finger on why.
Hi, I had this problem but i sprayed "metal cleaner" on a toothbrush and wiped the contact and now it works fine again :3
This happened to me yesterday. First the phone doesnt charge, it was at 25%, After that i charged it with phone turned off, then turned on and battery whas 50% but still not charging. Turned off again, plugged the charger and it looks like was chargin, when i turned on again it was at 12%, like the charger just discharge it xD. After that the problem began, the battery icon shows like charging when unplugged....
Looks like i managed to clean it with a needle, now the chargin notification is gone, and i can transfer files via USB to my laptop, but still i cant charge with AC :-/
And when i plug the usb cable, the notification icon comes again :-/
OMG Thanks it's alive it's alive
After some time my charge port started giving me issues again. I tried messing around with it but all I did was break it. Eventually I bought a replacement flex cable and ended up installing it myself. Very easy to do. Looked up a video on YouTube and in 10 minutes my phone was charging again.

And i used this guide to pull my nexus apart.

Just be very careful on step 6 "Some have reported the cable is soldered to the mainboard. This was not the case on this CDMA version. It may be soldered in newer revisions or the GSM model."
I broke my volume down because the guide didnt have a warning !
I hope this might help anyone else who is having problems

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?

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
Sent from my GT-N7100 using Tapatalk 2
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.).
ive been having a problem with this phone for a while. it has a problem with turning on and statying on. i will set it on charge while its powered off for atleast two hours, but as soon as i turn it on it will last for about 5 mins and turn off.
i first replaced the battery and it has the same problem. so i replaced the charging port and it was working fine for a few weeks and now its back to the same issue. i cant even get it to charge now
so just trying to figure out what kind of other components it could be
Disclaimer: You're at a more advanced level than I am. I've never done phone repair, and I don't know enough about phone hardware to say if there are other components that could be responsible. I'm a software guy.
That being said, I'll chime in with what I do know, on the off chance that it's actually helpful.
When computers get too hot, they do an automatic thermal shutdown to try to prevent permanent damage. I assume smartphones do this as well. You're on XDA, so there's a good chance you like to tinker. Did you overclock the phone? Overclocking generates more heat, which could potentially lead to a thermal shutdown or permanent damage. Or you might be using or storing the phone in a hot environment.
Have you tried using a different charging cable? Maybe the cable or its connector went bad. You could also test the cable with a different device. Maybe the wall outlet, etc went bad. Did you check the connectors that the battery attaches to, to make sure they're clean?
When you opened the phone to replace the charging port, maybe you didn't put it together quite right, so over time something came loose or got pinched. Desktops and laptops use various types of adhesives such as thermal paste, and computer technicians have to remember to reapply new adhesive when putting a machine back together. Maybe phones use some adhesive too, and maybe you forgot to reapply it?
Hopefully someone more knowledgeable about phone hardware will chime in, but the Incredible 2 section of these forums has been a ghost town lately. That's why I'm giving my two cents. If it were me, I'd just buy a new phone.

well i greatly appreciate your lengthly response. to be honest, it is my mothers phone, which is why i want to try and fix it. i gave her an iphone so she really doesnt need this phone but i would like to figure out what is wrong because i do like to tinker with things. i have tried different chords, wall outlets, usb ports on the pc etc. i will reopen the phone to see if everything is back together, because thats the only thing i can think of from what you mentioned.
thanks again. if anyone has had a similar problem, let me know
sounds like you're either having a battery issue or need to replace your charge port on your phone. its a really simple process all you do is order the port from like amazon or ebay and the old one on your phone just unplugs from your phone circuit board there actually is a tutorial forum in the development page for the droid incredible 2 that gives you instructions on how to do this. hope this was of some help to you and if so please click thanks.

The OP already tried both of those things.
Oh ok yeah i just noticed where he put that. Hardware problem maybe. Im more into software myself than i am hardware.
MINE TOO! Omg
This... it's too much. Okay, a month ago the damned power button got too hard to press in, which should have been a warning that the hardware was getting faulty I suppose. But I downloaded an app that let me use the volume button to turn screen on/off. (I won't say which because I half-blame it, unfairly, for killing my phone
(Sorry, I'm still —mourning! the death of my phone I guess.)
The app was an ugly solution, I guess, but it worked. (I couldn't turn the screen off easily, so I set the screen-off to 10 seconds.) And I hadn't used screenshots in a while so that was no big deal; and my ROM could get me to Recovery easily enough, so screw the power button, right?
But then last night, my phone STOPPED CHARGING! I did a batt pull, tried new cords; turned off every useful app. I even went back to stock ROM, which (even though plugged in) left me with 20% batt. Might as well have bricked it, I guess.
Nothing worked. I was able to turn bluetooth back on so I could use my Air Droid acct to get my on-phone pictures, at least (everything else is safe on the SD), and then I charged it overnight in the wall and hoped for the best.
I was pretty thrilled to wake up to 100% charged! —For a few minutes. As soon as I unplugged it, it started discharging fast, and then not even the wall charger stopped it from discharging.
After brooding, for a few hours, I called Verizon tech. The tech (VERY nice, admittedly) said my Dinc2 was just dead. (Damn they're good: he was more sympathetic than a doctor delivering bad news!!) —But I feel so lost. He offered me a DNA or a Dinc 4G (and some motos and crap), but said my Dinc2 wouldn't be worth fixing. He said the power button alone was a PITA, but the dongle thing you plug the charger into was likely the problem, AND it might be the battery. Maybe he said other problems, but ultimately he suggested some pre-owneds he had for sale (I'm trying to keep my unlimited data plan), or try PhoneKarma.com. (He said he didn't recommend eBay, where they have Dinc 2s, but I'm not sure why.)
So ...do Dinc2s just have power issues after (?) 3 years? I guess that's a pretty good lifetime, but boy is it depressing. (I know — hooked on a damned phone. #Sucks.) I mean, it would be stupid to fix this one, or buy another one, right?
@Trebuchette, no matter what machine you use, rechargeable batteries do not last forever. Order a new battery from Amazon or eBay and you should be fine. They're pretty cheap and easy to replace. http://www.amazon.com/HTC-Incredible-6350-BTR6350B-Packaging/dp/B0064SI3QA
A case might make your power button easier to press. The OtterBox Defender is an excellent case that you can get for $15 used (very good condition), if a new battery successfully fixes your problem.
Hey: might be worth a shot! I did try another batt, but it was older too. And I didn't think of an otterbox at all, tbh. Thanks! Might be worth a try!
Hey: does it matter much if my USB cable is LG or whatever? I tried several different USBs too, but I'd been using this LG one (no idea how!) for probably about a year.
No, the brand of micro USB cable should not matter. It's a technical standard.
Don't buy a case until you've verified that a new battery actually fixes your problem. If a battery doesn't fix it, it's only a few bucks lost. In that case, I would then get a new phone.
i just came back to this thread after i basically put the project on hold for a while and wanted to see any new suggestions. so after leaving the phone alone for two months, i pluuged the phone in and i saw that orange ligh indicating it was charging. so far so good, im not using it as a primary phone which is good, but that would be my suggestion is to give the phone a rest for a while
EDIT: yeah scratch that, its doing the same **** now
Hey guys,
So i flooded my phone, dried it, left in rice for 2 days and now when i connect it to my charger the screen goes up after a minute or so but its not charging. My screen shows battery icon with a bolt inside and a zero below, or battery with a cable inside and zero below. Any idea what can i do to fix this? I can boot to bootloarder mode, but when I'm trying to boot to recovery/other modes it goes back to 'charging screen'.
Thanks in advance!
The battery is eeprom controlled so you probably damaged it when teaching the phone to swim. Flashing will do nothing for it.
Putting the phone in rice is a bad idea as it isn't as absorbent as you think. You should have left it over a radiator for a week or so to evaporate the water before even thinking about switching it on, but by then the damage was probably already done.
If it doesnt start working in week or so then expect it to be expensive to fix.
Beamed in by telepathy.
Not sure what eeprom is, but if its in the part below, then i could replace it myself with no problem. What are Your thougts? I know that more thing may be broken, but if it would go back to life i would be glad because I don't want to spend money on any new phone, maybe apart from S8/pixel but its expensive as hell.

Cheers and thanks for previous reply
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
