hi, i had an xt910 with bad mobo that didnt charge.
i swapped it with some usa variant either xt908 or xt912 not sure yet, as i can flash both roms on it.
anyway, everything works fine except gps is not getting a fix.
i read this phone has a wifi/gps combo chip, so the chip is fine as the wifi works.
i tried all the software solutions and different roms, this is not the issue i think.
what i do think happened is during the replacement of the motherboard i damaged the gps antenna connectors.
i noticed there are many small copper pins around the frame, and where i think the antenna is, the copper was dent, i tried to restore it, but i broke a piece of the pin.
and even after i "restored" to what seem a good position for the pin, i couldn't get a fix.
i looked at all the teardowns and there is no mention of gps antenna, all i could find is where the chip is, so i circled what might be the pins of the antenna.
so my last hope is try to add a copper tape/wire to the antenna so i could get a fix, but i need to know the exact location of it.
i circled in red what i think is the antenna.
im waiting for the copper tabe to fix, so in the meanwhile i would appreciate anyone that can point me to the antena direction

Does anyone know what the connector for external antennas on the back of the wizard is called? I want to build a custom antenna that I can embed into my clothing to improve reception at school. I can't use a regular antenna since phones aren't allowed to be used at school.

The antenna part is:
P/N:36H00341-00M "Antenna Pre-Assy, AMPHENOL, GAN40023, PRODIGY"
I am attaching 2 pictures, the first you can see the Antenna Assembly (silver chunky thing above the case) and a second picture of the main board. You can see the brass connector just above the bar code.
This connector type is an AMPHENOL (brand) FME...at least it should be. One of these days I'll get and antenna.
--M
PS when you get the antenna, get a connector that at least has a 90degree bend in it. You might want to try http://www.wilsonelectronics.com
I have one
I grabbed one of those adapters, unfortunately, I cannot remember where. One end (FME) fits into the back of the phone with the 90 degree plug, the other end on mine is a TNC connector. I got that as I had a couple of spare antennas that use TNC.
It does improve the reception. I use the antenna's in the vehicle when on the highway to maintain reception. (I have no problems in the city)
Depending on your device, you may want to update the Radio ROM, if you haven't already. This doesn't flash/reset your phone, but does update the radio. This might resolve your problem without spending any money.
I am using the 2.47.11 Radio ROM and it did make a difference. My device is the T-Mobile MDA (Wizard). In a particular location, where I would get zero reception, I now get one bar...and that's all the difference I need.
P.S. If you do get this adapter, be careful when plugging it in and during use. Remember that FME connector is attached to the circuit board.
ok i may have this completely wrong as i have not tested it yet but i noticed on the back of my tg01 i had 2 round black stickers, one top left, one middle left.
After peeling this stickers off i have 2 little ports which look remarkably like the ports used on internal wifi chips (laptops, nintendo ds) which the areial plugs into for the wifi signal
We can now enhance the tg01's wifi reception with a little careful wire placement
i hope his helps someone with the wifi reception & maybe better battery life as its not having to try so hard for a signal
comments?
Are you sure one of those are not for a external GSM antenna? Like for using in a car
no, i did think this but they are to small. only 2-3mm across. i know what im talking about when it comes to hardware, they are definitely wifi ant. ports.
http://images.google.co.uk/imgres?i...internal+wifi+connector&um=1&hl=en&tbs=isch:1
this site has loads of pics and prices for the relevant hardware
its called an ipx connector, the pigtails they sell can be used to act as the antennae.
i think this could be a good thing
that connector u linked in is a standard connector used with laptop wifi card , they have a little pin in the middle , the connector on the tg01 has no pin in the middle , the ring around it is the shading
kk here is what i know so far.....
most (if not all) builtin wifi chips have an antenae port out, i know this through research with the nintendo ds, and internal laptop chip on various laptops ranging from toshiba to sony.
they commonly have two of the ipx ports for the loop with the wifi flylead.
it may be possible qualcomm have used a proprietary ipx adapter for extra sales through the hardware of there chipset or toshiba have gotten the grubby little hands on it and done it that way
we need people who want to run an experiment on this and find out if they are what i think they are or if im completely wrong
volunteers????
i happen to have a connector ur looking for , but , it doesnt have a pin in the middle and its 90' angled so it wont fit unless i get the back cover off ... with that said , i dont have a 3angled srewdriver thats needed
... ill make some pics later
could it be possible the snapdragon chipset has done away with the pin for a design point? they may be purely there as a dud bit of hardware as qualcomm have directly etched the wifi ant onto pcb and not allowing the flylead?
or...
they may be semi usable with the core (the bit with the pin) etched onto the pcb and the earth allowed to be enhanced by just using the outer rim of these ipx ports?
or...
im totally wrong and as well as the usb host function you could attach a couple of jump leads to the beast via these ports and jump start that big ol v8 what keeps stalling?
Perhaps they could be test points, do you think you can show us a photograph?
i will upload pics tomorrow, they wont be great quality as i have to use my wifes blackberry for em and it dont take great up close pics.
test points are a possibility, tbh it did cross my mind but usually there just dotson the pcb, not ports, but it is a more advanced piece of hardware.
just out of interest but if you were to hook it up with the ports via usb, there would be a chance you could damage it because of the power usb ports output. if it turns out to be wifi then your gonna blow the chip or worse.
but if you want to try it then by all means psot results
hope this help

nice one!
looks like it connects two aerials for better wifi/radio
compare the connector with this
i558.photobucket.com/albums/ss28/linyedongwyl/Intel-5300-half.jpg
thats the connector for the ipx that has been linked earlier , this is a little different , it would be nice to see what the connectors look like on the tg's wires?
alrite , lets compare this baby to the xperia x1
www.phonewreck.com/wiki/images/b/b2/Xperia_x1_pcb_1.jpg
u can clearly see it also has two unused connectors of the same kind wich appear to be unused /but on tg the two upper ones were connected on the pcb!!!/
as for the interconnection of unknown function on the backplate they used the battery cover to pass it thru(the cover's back is unpainted on thoose specific points to give conduction) if it were to just hold the cover in place the would of left the paint on
see the four pins on the phone around the battery
www.ubergizmo.com/photos/2009/3/xperia-x1-battery.jpg
so i was right, we can get better wifi signal with these ports.
and then
better signal + less energy needed = better battery life
and the SE using the conductor pins for the back cover they have used that on the old w series of phones to. no real idea of what it does though
thanks to those who uploaded pics, helped out a lot with explaining what they are and the circuit detail.
so who' gonna be the first to install this on there phone and so testing for battery life and signal improvement?
Did you get anywhere with this? Very interested!
This sort of thing would surely work:
http://www.ebay.co.uk/itm/800-900-1...099221?pt=PDA_Accessories&hash=item4ced70add5
IPX antenna.
Alternatively.. what would almost 100% work is a replacement antenna cable for the tg01
Although I could be wrong... if you look at this review of the LG P990 (Optimus 2X) you will notice the two different types of connector: http://www.anandtech.com/show/4144/...gra-2-review-the-first-dual-core-smartphone/9
External aerial points for testing the phones at the factory? Can they be used/abused to get an external or bigger aerial setup? What connector is that without the pin????????
Update.. is it an MMCX connector ? (or even MMCX-KC). I am tempted to buy one from ebay (although my TG01 is bricked LMAO, at least I'd know if it fit!) Pretty certain now it's an MMCX connector. Now trouble is... you can get that connector for GSM and GPS... so what are the connectors for I wonder.
For example.. I have terrible reception in the office so having a bigger external aerial on the phone may help, but I'd be interested in a better GPS cable as well Let's have some fun!
EDIT: OR.. I just had a look at my Moto V3i external connection and that is almost identical to the connectors on the TG01.. and it looks like you can get an aerial/antenna kit for the v3/v3i Might give it ago but it's pricey at about £20 :-(
LMAO @ this link: http://www.ehow.com/how_7580234_increase-reception-v3i.html Fancy testing a paperclip guys?
Well... I just ordered a 3G/UMTS antenna from china (so will be a while) with a MMCX connector. I will let you guys know if it fits AND works
Another edit LOL: I also just ordered another external antenna. This time for the V3i RAZR, as it looks like it has the same connector type as the TG01, so will give that a go. Only cost £8.05 for the adaptor and the antenna, so not 'too' bad for something that should fit.
Dear All,
After that my Atrix drop on the floor of my car, the GPS is not more working...
I have figure out that the antenna wire is now unsoldered from the battery cover. I have tried to solder again but is still not working.
Any suggestions?
Thanks
i don't think antenna is soldered to battery cover.
maybe the back cover of the phone.
try some apps from the market (GPStoolbox)
So I ordered an external antenna for a USB modem that I use in my home, and I got curious. I attached the adapter to BOTH of the connectors individually to see how my service would improve, and I think it was a mistake.
I get no service whatsoever now. I actually have to put my phone up to the signal booster I have in my phone to get any service at all.
Luckily, I had another S4 and I changed out the motherboards so I didn't have to go without a phone.
I'm wondering if there's anything I can do to restore the functionality of the other motherboard's radio. Even if it means DIYing a solution.
Below is an image of the connectors that I attached the external antenna to. Can anyone help?
It doesn't look good:
http://forum.xda-developers.com/galaxy-s2/general/external-antenna-socket-warning-t1273292
You have damaged the connectors inside the antenna socket (very easy to do, as I found out). This has switched off the internal antenna and you have four basic options:
1. If under warranty, return it and hopefully they won't notice you messed it up and replace the motherboard.
2. Rig up a permanent external antenna using copper (or other) wire.
3. Fill the socket with solder to rejoin the connectors and re-enable the internal antenna.
4. If 3. fails, replace or completely remove the antenna socket and solder the transmitter/receiver to the internal antenna on the board (how's your micro-soldering?)
I messed up my 3G antenna, which is in the same position as R1 on your board, but on mine it is labelled L1 and I only have one socket. Your other one is for 4G, I think, so if you have messed up both it's double trouble.
Well, I suppose I've got nothing to lose by trying this out and failing. The only reason I want the other board is for the older baseband version, and the fact that I have safestrap installed on it.
Hi there.
I have a G5 as my backup phone. Recently, I've replaced the fingerprint scanner (it stopped working as a button, no cleaning would help, so I've bought new part online and replaced it), and after that I have no signal (-1dbm 99asu). Not even an alarm call is possible.
From my research, the antenna module is the bottom slice of the phone, you attach the battery to (one with mic, USB-C and bottom speaker)? I have both original bottom part and a Cam+, no signal on either of them. Where else should I look for any damage, that would lead to my problem - no signal at all?
I have a similar problem. The signal is very low everywhere, I tried to clean all the contacts between the bottom part and the phone, and nothing changed.
Me too i have a problem with the signal since display change. How can i get it fix. The phone has very low signal and it has network only on 3g on LTE it hasnt any network and 2g signal doesnt have.

Well, the pcb or mainboard has a small flex type antena on the back of it, it's black and has some lettering on it and it connects using coaxial type push connectors, also the phone connects to the aluminum case via some exposed pins on the mainboard, the case acts as an antenna also, if you need pictures I can take some tomorrow, I work in a cellphone shop and I fix an LG g5 almost every day, we have some main boards laying around, you most likely bent one of the pins that connects to the case
nah i got the same problem here after disassemble the phone. I already clean all things that contacted with the backdoor or with mainboard but the problem still there. Only got 0-1 bar of 4g even it near the tower until it change to 3g with the same condition. but the 2g signal is always full bar.

so is it located on the mainboard or part of screen? could you take some picture of it :crying:
