I recently replaced the LED/glass/digitizer assembly of my E980, US version phone. The wi-fi antenna on the left side of the housing came loose near the bottom. It turns out that the connector was still in place but the wire was torn loose.
I see there are two connectors: one for the antenna already with the phone and then another smaller one next to it. Is the smaller one active? I have extra antenna cables from my Galaxy S4, but I just want to make sure that before I try it, that the port is actually active and not just a female connector that is a place holder for overseas variants of the phone.
Thanks very much.

Hi all.
Im hoping someone can help me out.
In the process of building the wireless charging hack for the htc desire and the prototype works fine.
However at the moment i have connected the induction coil circuit to a micro usb plug which then plugs into the desire. This is an ugly solution!
I would rather solder the induction coil circuit straight to the circuit board but am having trouble identifying where to connect to.
Has anyone looked into this and able to show me a +5v solder point on the board near the micro usb socket?
Appreciate the help.
Hi all.
Sat down with my multimeter and the desire in several pieces! Lol.
Finally found the contact points on the main board for the micro usb power.
Have now attached the induction coil to the phone main board and slipped the back cover back on.
Now I have a a desire with wireless charging using the palm touchstone but still retaining the ability to charge via the micro usb if needed!
I love the desire so much! is there nothing you cant do?

Good idea!
I spent ages trying to build a slim line micro-usb plug that could easily plug in and out if I needed to charge away from a touchstone but it was not very pretty and in my frustration I took apart the phone trying to find a points on the board instead! Initially I was planning on soldering to the micro usb +5v pin but that was way to hard so instead I searched for a contact on the pcb and eventually found one.
From the outside, the phone doesn't look any different from any other desire which I prefer.
Here are some pics. I can't take pics of the internals as I've put it all back together now and don't fancy the risk of breaking the tiny wires!
Attached some pics though as requested.
Nice project
Sent from my HTC Desire using XDA App
hi , i was thinking of doing this , when i got my phone apart i noticed two holes in the plastic that covers the microusb with two gold contact underneath, are these ground and 5+ i would check but my multi meter is bust
Hi,
this project is great and I also want to build this.
Could you please indicate the appropriate contacts which you used on one of these pictures:
http://blog.afkbio.de/index.php/uncategorized/anleitung-fur-displaytausch-bei-htc-desire-teil-3/
Did the copper coil together with the PCB (there is a PCB needed, I guess) easily fit into the HTC Desire casing? I tried to fit 5 sheets of paper there but couldn't close the case afterwards.
Do you have any more details? Will the Desire hold on the Touchstone or did you add magnets somewhere?
Hi.
Regarding the contacts, I used the 0v of the microusb socket.
The part of the pcb i soldered the +v to is not shown in those pics but if you look at pic 7, there is a square contact on the hidden side of the pcb connected to the microusb socket at the bottom of the phone. That is what i used.
I found that the case fits on fine and the phone is held on ok to the touchstone without any additional magnets but maybe that could be strengthened by thinning down the backcase a little.
i hope that makes sense. very hard to describe without pictures! i wish i had taken some when i did the mod!
I asked because I was afraid that I would need a "bigger" back cover as used by some extended batteries for the Desire. So you just extracted the coil from the Pal Pre backcover together with the board and put it on top of the regular Desire battery?

If you are talking about the ones to the left of the battery (the only ones i could find) thats +2.6V
Does it work through a case? Such as otterbox commuter?

I'll find out tonight, i'm going to destroy a powermatt cube and give this mod a shot.
Ok, so now I got my hands on a backplate and a touchstone and already disassembled the stuff.
The point is that I still need to know where to solder the 5V. How can I measure the various golden points? I have a multimeter, but where do I probe the black (mass) pin and where the red one (sample)???
I'm a little confused.
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!
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:
i.imgur.com/yCsGkWw.jpg
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:
i.imgur.com/QRvxlkB.jpg
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
Okay... i´m trying to make a mod for my Z1C to make it qi compatible....
I have the magnetic connector from a dock (which is broken).
So, using the connector + cover + glue can make it work.... and of course, need to solder the receiver to the connector....
But, the big question... which receiver should i use?
First of all, i´m from Argentina... so i have a limited access to receivers.
I´ve seen here receivers from Samsung Galaxy S3, S4, S5, Note III and Note 4, and a few others generic...
The maximum current that could find was 650mA... but read some comments that the output 1000mA is a lie... and there is no difference between the receivers...
So, which one should i buy?
Thanks to all!!
Finally, get a 700mAh receiver, and cutting out the cable, mixing + soldering + glueing it all together, and now it´s working....
Samsung GS4 1000mA QI receiver
I have a few Galaxy S4(1000mA)/S3(800mA) QI receiver cards.
The cards are different depending on the contact points location in the phones.
So you just soldered the internal magnetic charging points to a QI receiver card inside the phone?????
If you have the QI Receiver inside the phone (only real place for it), how much pressure does that place on the back cover??
The back cover tends to break away from the frame without much effort, so having the raised 'bulk' of a Qi card in the phone would only add to the pressure for the back cover to separate.
On Samsung phones (GS4 which I've added QI cards) it does take a bit of brute force to chip the back cover on again and some GS4 aftermarket cases/covers can not be used with the QI card installed due to the back of the phone being ever so slightly raised.
I have the QI receiver cards, glue seals rings for Z1C back cover and the Qi chargers and it is something I have thought about, but with three working magnet DK32 docks around the house, it's not something I have advanced at this time.
Well done for getting it to charge via QI charger if that is what you've done.
Maybe a photo would be nice.
Okay... now, the photos:
The tape is over the receiver module.
The original contacts from the receiver were removed, and over there, was soldered some copper tape (that can be seen in the photos).
The contacts were made by opening-cutting a magnetic cable, soldering it to the copper tape, and then glueing it to the cover, to maintain position.
The charger seems to be very picky about position. Searching over the internet, seems to be a common issue with this model...
Hope it´s usefull...
Well... about the charger, there seems to be an easy fix to it's pickiness... Take off the upper side... That way, the thing will gone a cool itself, and the connection will become a lot easier...
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.
