Hello xda!
I replaced my own battery, I followed some tutorials on the YouTube to see how to do it and was pretty easy! I was SUPER careful while i was doing it so I don't believe i have broken anything. After reassembling the device is working great but i had no cellular signal!
popped open the back, everything appeared to be in order.
Any ideas and/or suggestions?

Try reconnecting the network antenna(connected to daughter board and motherboard).

unless it was under the battery, no other connectors were disconnected.
Can I "assume" it's one of the many in row with the battery? If so, I'll go back in and make sure that they are seated properly
Thank you

Even if you haven't touched it,just try reconnecting it.It is the main thing responsible for network/signal.The WiFi will still work fine without it though.
The network antenna is actually contained within the back cover of the OPO, as is the NFC antenna. If you look closely, you'll see contact points where the back cover makes contact with the 'main' body of the phone via pairs of small brass springs. If it were me in that situation of not having cell signal after battery replacement, I would remove the back once again, and carefully clean the contact pads on the inside of the back cover. I would most likely use a pencil eraser and VERY lightly 'erase' each and every pad, wiping them off afterwards. Then closely inspect all of the brass springs on the main body for any signs of being bend or somesuch.
Not saying that will take care of the problem, but I do feel that you have a very good chance it will solve it.

Just did that. I noticed that the push pins had made indentations in the back case. I cleaned them, and they function correctly. Still No cell signal. SIM card is recognised when inserted.
Maybe a new back case?

Before you do that, double check the connection at the point indicated in the photo I'm linking to below:

I'm at a loss at to what the problem could be then.. And all you did was to remove the back, remove those 9 screws, pop that cover off, unplug the battery, swap batteries, then re-assemble? There's no scenario I can think of that would have caused your network signal to stop functioning.
The very last thing I can think of, and it's what I would do if it happened to me, is to flash the firmware for the radio using TWRP. Just check in your settings to find out what version firmware is being used for your broadband, grab a copy, and re-flash it. It's quick and painless, and just might to the trick. Don't know until you try, and it certainly won't hurt anything.

My bad, that was it. I "had connected" it. and that's when I replied. Took it to a cell repair shop. tech opened it up, and connector was off again. Took some time, and he got it snapped in place for good,
I have signal

My wife's phone got water damaged a few days ago and I took it apart and removed as much water as possible and put it in a bowl of rice to set.
I finally tried turning it on today and it seems to work fine (I think, syncs etc.) except that the screen does not power on. I can see the backlights when I look at it from an angle so it appears to receive power of some kind.
I took it apart further to see if I could see anything and I found that on the display cable there is a black area which looks like it is damaged/burnt on the cable. There was also a little bit of black on the connector but I believe I got most of that cleaned off, but the area on the cable does not seem to be able to be cleaned.
I don't really know anything about electronics or parts of a phone and was wondering if anyone that did could suggest what my next steps would be to restore the phone/screen to operational condition? Part replacement etc.
Thank you.
It sounds like the chip connected to that cable got fried, hence the burnt spots.

If that's the case I'm assuming there isn't much I can do? I don't want to solder anything but could can replace anything that just snaps in.
Thanks.

Bump for last ditch effort to get some opinions before giving up.
Recently my phone was ran over. i replaced the screen which was damaged beyond salvage. after some investigation because my phone was not connecting to the network, i looked beneath the metal bed for the sim card/nfc. i wanted to know if it is possible to put it back on. if it is i wouldn't be doing it myself as i don't have a soldering station handy. i want to make sure it's doable.

if it is possible i think your best bet would be to use heat less solder its like glue

Hi all,
First off I would like to thank anyone and everyone that reads this thread, it helps me out if you have any information that could help me out here.
About a week or so ago my girlfriend dropped her Nexus 5 in water, and removed it almost immediately then brought it to me. Sadly the damage was already done and the screen was black. I got the back off and got as much water out as I could shake gently, and the screen still had haptic feedback when I touched it, so I messaged it and it displayed the notification light. This led me to believe the battery was ok, so we left the back off and let it dry for a while, and over time the screen and sound came back. We placed the phone overnight in dry rice, and for the meantime we put her SIM in an old S2. The next morning there was obvious water damage on the screen but less than before, and everything seemed to be working fine, games ran, music played, messages came and went on Hangouts, and when we plugged it in to charge it worked like a charm, so we believed we had gotten lucky, put it back in the rice overnight again and the next day tried putting the SIM card back in the phone.
The Nexus at this point asked to restart and we obliged, but this is when the problem started. It would get to the Google boot screen, hang, then restart, over and over. I tried going into recovery and I could, but no further than that. I am not an expert so don't know what would cause this, but I am led to believe that the battery and everything else is all in working order otherwise it wouldn't have been working and charging while it was on. I wonder if maybe there is a separate part of the phone used for BIOS bootup and it got damaged? Any suggestions or ideas on how to fix the issue would be met with extreme gratitude. Thanks for reading all this.
TL;DR Phone was dropped in water, aired out and worked fine, restarted for SIM card and get stuck in endless boot loop.

Take the device apart, remove the motherboard. Get some rubbing alcohol and a tooth brush.
Remove any shields that can be taken off to expose more components. Then start scrubbing!!! Continue until you get all of the green/white corrosion. If there are any black scorch marks on the connections, take a eraser and it will remove the burn mark, then continue to clean with alcohol. Also the flex cable connections would need to be cleaned also.
The next step is up to you, if you feel comfortable with it. Make sure all plastic and rubber pieces are off the motherboard. Then stick it in the oven on 400F for 30 min to reflow some of the solder that may have gotten damaged.
Put back together, you may have to factory reset if the software got corrupted.
It is still highly possible to recover the device.
Good luck!

I wouldn't go so far as reflowing solder for a dry-out.
http://www.amazon.com/o/ASIN/B000BXOGNI?tag=adapas02-20
can be attained at your local auto supply, simply disassemble the boards and give them a once-over spray and wipe-down. Reassemble, and then troubleshoot the bootloop, which may require a full stock flash. Good luck!

I am not reflowing to dry it, sometimes solder on the connections/components need to be reflowed when they got WD or the device will not function correctly.I have seen it more time that I can count.

There wouldn't be solder damage when OP acted almost immediately to dry it out. A cleaning, further drying should be all that's needed. One should NEVER turn on electronics until fully disassembled, cleaned and dried in any event.

The second the device hits air corrosion starts to build. Rice does nothing, it pulls a little bit of the water from the charge port and headset jack, basically what drips out. There is possibility that there is still water inside the device. He needs to open it up to scrub it down with a tooth brush and alcohol at least.The connections may break in time even after cleaning, that is why I suggest a reflow.

I don't disagree most of this up to the point of reflow, which should be an absolute, last-ditch exercise. If corrosion is a major concern, after cleaning with solvent, a Caig deoxit treatment would be my next advice, but I think reflow is best left to the experienced.

Thanks to both of you for your advice on this. I will go and get some of the cleaning spray you suggested and give all the components a good clean, and will look for any scorch marks that may have occured when it was damaged. I would try flashing the OS as well but I'm not entirely sure how to do that when the phone has not been set up for USB Debugging. I attempted to flash it after unlocking the bootloader, but that didn't seem to work either. I will report back when I have performed the steps and let you know if there has been any progress.
Thanks =)

And to the guy above, sorry if it seemed I was arguing. A few too many drinks at that point.
After opening the back of my phone and taking it apart to get a stuck sim tray out, my wireless charging quit working. What could I have done? I did remove the battery, but I made sure to plug everything back in. Was there a connector on the backing that I missed?

Make sure to press the back down toward the upper middle of the back (all around the "S" in Nexus). There's a clip there that must fully seat, or the wireless charging connectors won't make contact. It's pretty common to miss that one.
Note: I think it's actually a bit to the right (or, a bit "beneath" the letter S, when held in landscape), but I can't remember the exact location, so just press down all around that area.

After putting my phone back in its Spigen case, I seen a couple clips came loose. I pulled it out of the case and made sure they were all seated and tried it on the charger again without the case and it still isn't working. I really don't want to pull the back off again but it's looking like I might have to, otherwise I gotta see if I can get the phone replaced through my carrier and hopefully they don't find out the back was off.

Judging from the picture in that link, the clip I was talking about seems to be directly across from the flash, just to the right of center (as you're looking at the back of the phone... so, just to the left of center in that picture), so that's where you want to press down to make sure that clip gets seated. (I guess I didn't realize it was that far up.) You can see by the proximity of that clip to the wireless charging pins how not being fully seated will cause the pins to not make contact.

OK, I didn't realize there was a clip there. I'll give it a try. Thanks.
@jt3, thank you so much. That fixed it. Working now. I'm having some display issues though, don't know if it's related. The whole screen becomes a bunch of lines but goes away when I press the power button. I've seen it before and it might be Multirom related but I'm not sure.
And thanks @Henrock11 for providing the link to the picture to figure this out.
No problem. Glad I could help.

Glad to hear. Like I said, it's VERY common for people to miss that clip when replacing the back cover, so I figured that was a good place to start.
Just out of curiosity, what prompted you to remove the back cover? Button Rattling? Weak Vibration?
I just dropped my P900 and it went completely dark. :crying: There's no mark, not a crack, nothing, but the display is completely dark. The touch buttons on each side of the home button lights up, but the display does not.
Any advice? Or it is Samsung support next?
May the ribbon for the display is disconnected from the circuit board.

Yeah, maybe I should open it myself and have a look. Are there any warranty seals that I will break if I pry it open? I have all the tools necessary, but are there any guides for opening the P900? I wouldn't want to break anything...

This is a video on replacing the battery but it helped me when I re-soldered the battery connection on mine.
https://www.youtube.com/watch?v=VeSG0hHpAG8
I've opened mine a few times and haven't noticed any specific seals but mine was refurbished to start with.
Also I have the proper tools but found a guitar pick was easier to use personally on this tablet.
Starting at the power port to remove the back made it a lot easier for me, its pretty hard to get anything between the back cover and the tablet in other areas.

Sorry to hijack your thread but figured my problem might be related.
About 2 weeks ago I charged my tablet and stored it away. The other day I tried to use it and it wouldn't turn on. I tried to charge it but that didn't work either as there isn't even charging activity on the screen. I ordered a replacement battery thinking it might be that, but I was wrong. I still can't make it turn on. Any ideas what it can be? Thanks

I had a similar experience. 3 weeks ago the 1x my SM P-900 is out of its protective case, it falls 2.5 ft off a table. Hits the floor. No visible cracks or breaks. I could hear hear it operating but the screen was black. Took 3 weeks to talk myself up to it but I pried off the back & used a magnifier glass to c.a.r.e.f.u.l.l.y check every ribbon connect. 1 connector's pins were very slightly off alignment. Couldnt find anything else. Put it back together...Yes! Screen works. All seems good. Took the back off again & securely taped over every ribbon connect I could find. Long time intermittent screen flicker issue (when battery was below 40%) also seems to be gone. That has been the best, eye squintin', back hunchin', shallow breathin', micro-screw wrangling, time investment my non-hardware tech self has ever spent. Wooo!
