I recently took apart my Gnex to replace the USB flex cable. When I put it back together it wouldn't pick up any signal. I have determined that it is a bad antenna cable. I have looked all over but can't find one. Does anyone know of a phone that uses a similar cable of a similar length, or where to buy any oem part? (The Gnex uses one that is 85mm). Thanks.
Did it fix the problem?

I just replaced the display on my gnex due to broken glass and am having the same problem. I think I may have pinched the antenna wire. Did replacing the wire work? Or was it something else? Thanks!
I hope this is the correct place to post in since the "Accessories" section is not T-Mobile specific. I found a working replacement USB board for anyone who has one break or become defective or something.
For a little background I have a T-Mobile Note 2 and tried a "wireless charging" hack in this thread. I am terrible at soldering but I still tried soldering a wire on the USB board (above the USB connector) and I ended up shorting something and it started sparking so I don't trust the USB board anymore.
I couldn't find the T-Mobile Note 2 (SGH-T889) specific board for sale anywhere so I resorted to looking for one that was as close to possible, and I found the NT7105 USB board for sale on eBay (click here for link). I've heard that a different version of the USB board doesn't work (the phone won't boot) according to the mod thread I linked above so I was skeptical but the one from eBay works great and charges no problem. I'm hoping this also helps people who have charging issues due to a faulty board.
Hi everyones.
Under the cover of N7100 there is a connector. Maybe MCX or MMCX. I don't know.
Question is: the connector is for Wifi, 3G or GPS?
I would connect an external 3G antenna.
It's possible?
Thanks.
You mean flip cover? That is NFC chip dude

I'm pretty sure it is.
Connector marked as R1 = for 3G/UMTS.
If you have an LTE version, the R2 hole should be for the LTE signal.
*EDIT*
I'm not 100% sure.
But it makes sense if it is. The R2 connector is not on the N7100, but it is on the N7105. I don't see why they would add a 4G connector but not a 3G connector.
If it is on the side of battery compartment,they are wireless charging pins.
A Qi coil pad is connected via these for wireless charging.
I'm not be able to post external link, but I'll try.
Here is a picture of my phone:

The connector is the round one, female.
I've seen a disassembly video and seems that the connector is near to a thin cable that bring the signal to the 3G antenna on the bottom of phone.
See this:http://www.ebay.com/itm/Samsung-Gal...tenna-antenna-adapter-cable-3db-/370780049306
I always thought that these ports are present for diagnostic purposes.But I remember reading somewhere that R1 is for 3G,R2 for LTE,G1 for GPS and W1 for Wifi...but never cared to read further on
Do you mean that the connector is FME?
In the description seems there are 2x FME male connector but the connector is smallest that the female one that connects the antenna.
I think that only antenna is FME while the cell phone is another connector.
Remember that I've a 7100, not 7105, not LTE!
Hmm..maybe.
Acc to the description "Connect two ports together with only 1 antenna" means a single antenna can be used both for Lte and gsm(gps/wifi-maybe)reception...similar to a splitter(only in reverse)
In 7100's case only one input port can be used for signal gain boost in case anyone tries to use this antenna

Ok, but the question is still: the cell connector is...?
I've also found this:

With a single connector (phone side) and it's noticeable that phone and antenna connector aren't same kind.
Also... FME is a threaded connector while phone side there isn't thread.
@carsco
The FME connector i.e the threaded one isn't used to connect to the port on the phone but rather it is used to connect external antennas(yagi antenna etc.) to the cord,the smaller connector then is used to connect the port on the mobile device,I just dont know what is it called...

I've understood that the FME connector is on the antenna and not on the phone. OK.
The question of this post is, still: what's the name of the connector on the phone?
Still open question.
I don't suppose anyone found this?
I'm trying to setup an external aerial for an old Note 2 I've got so I can use it as an LTE modem.
EDIT: Found one in the UK http://www.ebay.co.uk/itm/271750904962
Just in case anyone else comes here looking
Seems my USB port needs replacing, I first thought I may have had some lint or something inside there as it wouldn't charge but after checking with a flashlight one of the pins had bent completely.
The only thing I can find for the original desire is eBay ID 380759842289
Can anyone confirm if this is right, or where I could purchase one from the UK.
Are they hard to replace? Would it just be the case of removing the 2 lower t5 screws, taking the antenna out of way and then what? Are they soldered on or ribbon cable?
Cheers
I had a similar problem, my device couldn't connect via usb but it was able to charge, so my first thought was the same as yours (about the lint). I tried to clean it and I found something like a little wire which was out of its place.
I ordered a usb port (about 1.50 euros) for that model and I followed this guide on youtube to disassemble the device /watch?v=8sYB_AM_jHE
You have to dissolder the old one and then solder the new which is a little bit tricky. It Worked!
For the replacement parts you can search on ebay for htc desire g7 its the same or use google you will find a bunch of them.
Hey guys, I’m on my second screen replacement, this time replacing the battery as well. While disassembling, one of the antenna cable connectors broke off of the main board. It is the longer of the two from the top board. I need to know what this cable is for, and if one of these other extra unused connectors on the main board can be used instead. It would be EXTREMELY nice to have a schematic/diagram. Thanks In advance.
