replacement w.fl (aka ipex mhf3) connector?

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

[Q] Moto X battery pinout/external charging ?

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

Moto G with Water Problem

Hi there. I had moto g 2 non lte this year. Sometime around spring of this year, i was on a vacation. While on vacation, I dropped my moto g and my bag into a river and thought i would never see it again.
A few days ago, the authorities said they had found my bag with all my possesions and my moto g. they shipped them to me.
I would like to know if there is any chance of recovering my device? So far, I've opened the back cover and saw it was covered in water. Some parts were also rusted. The display has weird purple blotches around the edge. I have tried to power on or charge the device. I have put the device in a bag of rice and put it in a warm area of my house.
Will I need to swap out any parts? Where could I find parts? I'm willing to replace parts. Also, where could I find instructions for replacing parts?
Thanks.

After sitting in water that long I'd be surprised it it ever came back from the dead. Also the worst thing you can do is to power on a wet phone. I would guess that you have some rust on the board, plus in the usb and earphone holes. I personally think the parts would exceed the value of the phone.

Hi there. I've opened up the main board, and I have not tried power it on. I've removed the battery, sim card, and buttons. The main bored appears corroded and I dried it off. If I dip it in 91% isoploryl alcohol, would it remove corrosion? I also saw corrosion in the ports. If I remove all the corrosion and water, logically the device would work again, right?

Anything is possible, you can also put a wet device in a bag of uncooked rice if no type of desiccant or silica powder is available. That will absorb moisture from places you can't see. As for alcohol, alcohol is a solvent and can dissolve the internal adhesives. If it was salt water, that's even worse since it dries and leaves crystals behind. I'll be shocked if you get it working completely after soaking in water. I'm surprised the sim card didn't get ruined.

At this point in time, I really don't care if the son card works or not. I just want to get to the point where I can power the device on and charge. I be read online in many places people suggested to dip your device in 91% isopropyl alcohol. Where can I get this alcohol and how much would it be? I have placed the device in a paper towel and put on top of a heating vent in my house. I'll see if that does anything.

That's regular alcohol that's sold at any drugstore or store that sells first aid stuff. You can buy it in different percentages of strength.

OH MY GOD. I CLEANED OUT THE INTERNALS, REMOVED ALL THE CORROSION I COULD WITH A TOOTHBRUSH, THEN SCREWED THE THING BACK TOGETHER. THEN I PLUGGED IT IN, AND GUESS WHAT, THERE ARE SIGNS OF LIFE!!!! The boot screen blinks for one second and goes away. There is a white led that constantly flashes. The device shows 0% charging. I have tried to boot it into recovery but the device keeps bootlooping. It turns on by itself, blinks white led, shows motorola screen, shuts off then repeats the process. I'll leave it to charge and see what happens.

Okay so maybe I reacted too quickly. I'm trying to get the device working. So far, I can boot it into fast boot mode and no further. My computer recognizes the device and can perform fast boot operations. I have tried to flash the stock firmware but the device reports error low battery remote failure on some operations. The device still does not boot. I plugged in the device for about an hour, but the second I take it off the charger, it cannot function. The device still is boot looping when it's plugged in. What should I do now?

Make absolutely sure there is no corrosion in the USB plug. After that, I don't have any ideas, something in the charge circuit has a problem or something between the battery and board.

I can't seem to remove the corrosion in the USB plug. Besides, I can plug my device into the wall or the computer and at least has limited function, however removing the plug will cause the device to loose power. The device shows up on my pc and I tried writing the factory image but the device is still in it's weird bootloop. My computer just keeps playing the USB disconnected and connected sound everytime the device does the bootloop. If I boot into fastvoor I can moto device manager to show and it says fastboot falcon s

That may be part of your problem. The corrosion in the plug could cause most of your problem. That port only costs 50 cents US, but I believe its tightly soldered in and if that's the case it would be very hard to replace without a special soldering gun.

Probabily your battery is dead

Moisture sensor too sensitive.

I can leave my note 8 in a humid room (such as the bathroom during a shower), and it will trigger the device to say that there's moisture in the device. Recently, i even had it in my pocket while I was working, port down, and it still triggered. The device can sit on a desk in the living room or bedroom for several hours without the warning going away. Anyone else having this issue? Or does anyone know of a way to disable this feature? It's a major pain in the neck, and moisture was never an issue with my Note 3. I understand the idea behind it, to stop the charging process if it falls into water (which would generally require an idiot to begin with), but it's too sensitive in my opinion. Already, it has prevented me from charging my device when battery was critically low on at least two occasions.

Sounds like moisture is getting into your device. I'd return it.

So, the problem was corrosion in my USB port. The Sprint store couldn't do anything because it's "liquid damage." Thankfully, I was able to clean the crud it of the port, but it's still a little finicky. Wireless charging still works fine... Thankfully. So, corrosion will trigger the moisture sensor... Ugh. At least I got it taken care of now.

You can only charge with wireless charging?

I used some vinegar and the eject pin to scrape the contacts clean, and corded charging works too now. But the moisture sensor doesn't stop wireless charging.
Probably would be a good idea to invest in this...

I would call samsung. For a device thats rated to be able to be under water for up to 30 minutes......corrosion in the usb port shouldn't be a problem in my opinion.

Just spray some electric contact cleaner in there perhaps? Bizare that Samsung would not use corrosion resistance contacts for the USB port.

Perhaps, didn't have any, so vinegar was the next best thing.

Phone got wet, cleaned everything, battery has voltage, phone is a brick

The phone got immersed in water for 1 second. Like a dunce, I didn't turn it off and it worked fine and I didn't think about it. 36 hours later, on 50% charge and not charging (after working fine all day), it isn't detecting a cell signal, it's saying 0B mobile data used for the time period instead of the gigs it was previously tracking (and had a presumably accurate number in the gigs of wifi data). All the settings looked right, so I rebooted, it booted up, and maybe 30 seconds after finishing the reboot, it instantly and completely bricked. Power button did nothing for minutes, power+down did nothing. Plugging into computer does nothing, charging didn't seem to cause any warmth although I'm not betting my life on that.
I dissected the phone and there were small amounts of corrosion on the parallel pins near the audio jack, miniscule amounts in some other places, and "significant" localized corrosion at the microusb port and where the battery connector plugs into the motherboard. If the battery connector on the mobo is bottom right, corrosion got near, but didn't get on or appear to intrude into the EMI shield to the immediate left or to the one right above that, but I can't rule that out obviously. I cleaned visible corrosion off/out, checked battery and it was 3.8V at the mobo connector piece. I detached the mobo to check the underside, miniscule amounts of corrosion, cleaned, put back together, still a brick, EXCEPT charging clearly creates warmth in the inductive charger/battery area, but power and power/down still do nothing (no corrosion anywhere near those buttons).
If anybody has any bright ideas for things to try to salvage this guy, or places to check connectivity to troubleshoot further, I'm all ears.

You could try the old fashion method of pulling out residual moisture by placing it in a sealed sandwich bag with a cup of dry rice for a couple days. Sorry this happened to you.

What about the connectors for the cable from the switch assembly? Just disassembling and reassembling has caused issues for at least a few people reported on this forum.
Also, there is a board as part of the battery assembly. Just because there is voltage from the battery, doesn't mean there is sufficient current.
On a really old battery, you can have trouble getting a basic charge (been there, done that). This problem resulted in an apparently bricked device. The solution for that problem was to use a low power charger overnight. Something like the USB port on a computer. Then unplug and replug. If the screen shows the bootloader basic charging animation (white vertical battery), the battery itself is shot. But you should be able to get it charged enough to boot using a fast charger at this point.

I only unattached that ribbon from the mobo, not at the taped-over connection, and I'm like 99% sure it's back in the mobo fine because I've reseated it a few times and it feels tight. I never touched the junction between the power button ribbon and the mobo connector ribbon so that shouldn't be it. Pressing the power button definitely feels like it's depressing what it's supposed to. But I'm not even getting to the dead battery screen so wtf knows.
The battery (would normally) have more than enough charge to boot right now. Battery life was in the hours for constant use and it's been charged enough. My battery didn't seem to match the one in the teardown. It has

written on the wrapping and it wasn't immedately obvious how to get it and the inductive charger disassembled and off the midframe (maybe it was just good adhesive since I saw nothing obvious holding it to the midframe), but I didn't see any corrosion issues externally.
