OK, so please help me I'm going mad here!
I took my nexus one apart to replace the microusb port, which was totally crapped out. After putting the device back together i get very low WIFI signal although everything else is working. I took the phone apart and one of the mini pigtail connectors was unplugged and possibly a bit squished. I put it back on and it seemed fine. When i turned the device on the result was the same... Wifi works, but only short range.
This leads me to think the Coax w.fl connector is broken or possibly i damaged the WIFI antenna foil (it is somewhat deformed).
The w.fl connector is like the connector that connects the wifi aerial in your laptop, only smaller, if that helps.
I'd love it if someone could point me to a cheap antenna assembly or just the coax cable.
Even better if someone know of a device where this is sold as a complete part (antenna and coax) i could mount it behind the battery cover and possibly increase my signal!
This lack of wifi is such a pain as i live in a low signal area and rely on wifi for data/sync.
Thanks!
You can buy a 100cm coax cable terminated with W.FL connectors from RadioSpares in the UK stock number 619-6387
So like an idiot I dropped my phone in the sink, the top side (where the audio jack and USB charging port are located) got the brunt of the water on it. I took the battery out immediately, let it dry out, tried starting it and it would boot and get a signal (while making a loud screeching noise), then lose signal and start getting really hot. It also wouldn't charge via USB. I took it completely apart and cleaned the circuit boards with PCB cleaner, there were a couple of spots where the corrosion had started that was barely visible with the naked eye, but very evident through a 60x magnifier.
Once that was cleaned up I let it dry out again, booted it up and it's working perfectly now with the exception of the Wifi and Bluetooth. When I try to turn either one on it just says "Turning wifi/bluetooth on" but it never starts up. I'm assuming that the circuit and/or antenna that controls both of those functions is either corroded or fried. My question is, does anyone know whether the antenna or circuit board for wifi/bluetooth is replaceable, and/or does anyone have a map of the circuit boards that would direct me on where to look for corrosion?

I believe they are on the main board, which is a significantly trickier replacement. If not, you could always get a used captivate for cheap (one with screen broken or something like that) and switch out the boards
Hey,
Does anyone know the pinout diagram for the moto X battery, the CS-MXT912SL
http://www.techtek.cz/CS-MXT912SL
http://www.batterybay.net/Battery-for-Motorola-XT912A-p/motorola-cs-mxt912sl.htm
I intend to charge the battery externally and try to get my phone to boot up.
I basically walked into a swimming pool (yeah I was that stupid to have the phone in my shorts ) with my moto X,
and after a lot of drying the parts and assembling it back, just the green light near the ear piece lights up for a few seconds- when its plugged into the charger.
I can tell the charging circuitry is damaged, since I don't see any voltage readings at the battery input terminals,
which seem to be affected very easily as seen in my previous post here : http://forum.xda-developers.com/moto-x/moto-x-qa/moto-x-battery-stuck-10-charge-t2845065 (motorolla fixed the phone for me after that)
Thanks for any help
Unfortunately chasing down water damage is usually futile. You replace one thing and find other things are fried.
Usually saving your time and money for a replacement is better than spending it on a water damaged device.
Usually they either are OK right away after being disassembled and in a bag of rice a few days.... Or they are dead. The fact you powered it on, or tried by plugging it in probably sealed it's fate if their was any moisture still present I'm afraid.
Sorry for your loss. ?

And questions go in Q&A. ?
Thanks for your reply Darth,
I did dry out each part completely before turning it on (diassembled everything, hair dried, left it in an air conditioned room - disassembled for hours) .
I understand what you're telling me regarding replacing the parts - in this case I really think( I have reasons for this) its just the battery charging section thats shorted itself out and drained the battery.
Does anyone happen to have voltage measurements of the charging terminals of the battery, it might help me start off with some testing.
My real goal is to retrieve the data on the onboard emmc storage before replacing the board.
Im going to attempt to either :
1. Attempt to power the board up by charging the battery externally
2. Attempt to interface the emmc in some way to retrieve my data.
I know this is a long shot, but any advice/help would be useful
Thanks,
As an update to this thread,
I hooked up the battery directly to my bench powersupply at 3.18v and the battery came back to life!
The phone booted up! and works perfectly OK (speaker, gps, gsm, 3g, wifi, display, everything).... except for the MIC which I think is dead.
I've ordered a replacement part from aliexpress and hopefully can use my MotoX fully again!
PS: the battery pinout was (+) all the way left and (-) all the way right on the battery connector.

Can you pm me the link to the mic? And was it the front mic that doesn't work? Cause my issue is the front mic as well since it doesn't work.

After someone stole my wife's Moto X, they threw it in the garbage where it mixed with some soda. I was able to track it down but then it died and now has the same green light behavior you're describing. Were you or anyone else here able to fix it?
I tried taking it apart and rinsing everything with 99% isopropyl alcohol, but nothing seems to have changed.
Hey,
Yes, I was able to recover my phone - I suggest you make sure the phone is properly dried out before you try what I did.
I had the same symptom as the green light, which indicates it doesn't detect a battery or the battery is completely drained out.
I hooked up the battery directly to a bench powersupply, applying 3.7Volts for about a minute (current was less than 1A)
after that as soon as I connected the battery connector to the phone, the screen lit up with the battery symbol,
and it was charging at around 40% (I had the usb charger connected)
The battery pinout is (+) all the way left and (-) all the way right on the battery flex connector.
Good luck! let us know how it goes
PS: I just received the mic part and am about to replace it, looks like the mic was the only thing that didnt survive the water.

Wow, it's weird that the phone wouldn't even try to charge your battery until you jump-started it like this. After that everything but the microphone worked? I'll definitely give this a try, maybe by transplanting the battery from my other Moto X. For now the green light on the bad phone stays lit for about 10 seconds before it turns off, and the phone doesn't seem to be able to do anything else.
Everything except the micrphones(s) works fine, from what I figured there are 3 mics on the phone.
The main mic for phone calls is next to the usb connector, this seems dead.
The second mic which is near the front camera, I *think* is the "touchless control"/"google now" mic, this doesn't seem to work as well.
No idea where the third mic is but Im pretty sure that did not survive either.
As of now its a bit hard to replace the mic, since I don't have a hot air station at hand,
I can use the phone with a handsfree headset for the mic and it works just fine
Hello! When i was replacing my digitizer i saw that little silver part was free after removing case. I'll link photo of this. Does someone know is this part necessary to work? Usually i have problems with battery. It can turn off like there's no battery left and it only turns on while it's charging. Does this part can affect on this problem?

That's a shield for what it seems to be the antenna circuitry. Has nothing to do with charging/battery.
It took a weight off my mind I've had problems with wi-fi, but it doesn't disturb me that much. Anyway, is this shield important? What can create this problem with battery? I mean, phone could turn off and couldn't rewoke. It only worked after charging it up for a while (battery usually charged to ~90%) May I buy a new battery?
I see on some sites that users are reporting this and some think that it's related to the security update in March. That seems to be when mine quit charging wirelessly on known-good chargers.
On mine, it intermittently will never handshake with the charger, start to charge then lose connection or never charge beyond a certain point.
Wondering if anyone here is having this problem.
This sounds like the issue people have had with battery connector. There seems to be a faulty battery connector or easy to break small piece. Many have reported this and have had to either fix it themselves, get another unit or pay to get it fixed. Search around you will see what I mean. I haven't heard anything about an update causing this. I have heard that there is a piece that connects battery to phone that breaks easily. I've read quite a few reports of this and how a slight drop can cause it to break and cause charging issues... Read one person put a piece of electrical tape on it and fixed it that way.. idk. That probably doesn't help much. I hope you get it fixed. If you think it's March update and want to rule it out install April update.

Check for a swollen battery. On mine the glass started to separate near the volume buttons. I didn't find it until I took the case off and inspected it carefully. I was able to get a free replacement. There was extended coverage for 4XL battery issues... maybe still available. My issue was not the same as the battery connector issues also documented on XDA.
Erratic wireless charging and swollen battery
This issue is related to the battery, but not the connector issue others are having. About 3 weeks ago I started experiencing erratic wireless charging. Sometimes it would be fine, other times it would just stop for no reason, or not even start...

That was it exactly.
I talked to them and they escalated me to the "product safet6y team" and I'm waiting to hear back from them to see if they will replace it.
I was heartbroken when it lost wireless charging because I really wanted to keep this phone as long as possible and hated that something was broken. It's almost perfect in every way (and no notch or punch-hole.)
I also had the Soli unit go bad and they replaced my phone early on under warranty. I think LG did a great on these as the ODM, but it looks like their component sources were the problems.
Thanks again for the excellent help.
So I was having the same problem. I had to pop the back off my phone. You can see where the wireless charging pad has a spot where it contacts two pins on the phone side. I bent those two small pins slightly upward and put the back back on. YouTube how to get the back off I only used a small pry tool and my fingernail to bend the pins. You don't need to unhook the back. You can do everything with it connected.
Go slow be careful Good luck
