Hi guys, I had an old HD2 mo-bo that I want to resurrect, but one of the radio prongs fell off, causing very bad signal. I want to solder a tiny piece of cat5 wire from the pad of the broken prong to the one next to it (refer to pic). I would have done it already, but the connection pads on the antenna is separated.. I have two pics here to reference:

Is it ok if I bridge the contacts on the motherboard? I'm afraid that it would cause signal confusion.
Thanks in advance!
I would find something suitable to shape & solder to motherboard that will act same as spring contact that missing ...

So I bought a new housing for my O2 XDA II Mini, during the removal of the display ribbon I broke the little black part on the display connector which holds the ribbon down, and after hours of trying to get the ribbon back in and secured I have bent the pins in the connector to buggery.
The ribbon appears to be untouched, however the connector which the display ribbon goes into is broken.
Is there anywhere I can get hold of one of these little connectors to replace my broken one, obviously very sensitive soldering will be needed to remove the old one and solder the new one in place.
Alternatively, does anyone know any mobile phone repair shops in Auckland, New Zealand who would be able to help out with my situation?
I fear all i'm going to hear back is "the motherboard needs to be replaced", however I am determined not to go through this route, as I am a poor student and the phone sounds as if it functions fine, makes the beepy noise when first starting up on the setup screen.
I was very careful with the actual screen unit while removing it, and I have had signs of life earlier on in the broken connector episode, however I can no longer get anything showing as I can't fit the cable in.
Cheers for any help.
Anything would be appreciated.
"obviously very sensitive soldering will be needed"
And that only can be done by machines/robots. I don't think humans are even able to sloder those kind of connections...
But, could you post a picture? cause I might have suggestions on how to fix it. One would be to bend back the pins on the tiny slot with a toothpick and when done to tape the flatcable, so it stays there.
I've maybe got a spare creen for you.

Hi, I've still got a SPV 500 and a MDA Compact, need to find it if you want you can have my MDA Compact screen.
Just PM if you are interested.
My Hermes has been suffering from screen whitening for couple of weeks, when it one day stayed all white. I've taken apart my Hermes and reconnected all connectors I've seen, including D-Pad connector, tightening and loosening the screws. Nothing worked... What should I buy? Do you think that the actual screen may be faulty? Or maybe the flex is damaged and I should buy it?

I have been reluctant to answer this, because there is no guaranteed answer. You have tested and reset the connector, but did you try placing some padding on the d-pad chip - to push it more firmly against the d-pad board. It has been quite successful for some members here. It is thought that a common cause of the white screen is a poor connection on the chip.
You could try getting a new d-pad board or a part from a second hand device that does not suffer from the white screen problem. If you know someone with the correct equipment you could also try re-flowing the solder on the board.
But I would say that a new board is not guaranteed to solve the problem as it is still possible that the flex cable may be faulty (or it's connector.

First of all, thanks for answer.
Yes, I've tried pushing it harder. Also I unpluged D-Pad and tried to turn on- still white screen. Unfortunately, I don't have access to any spare parts of this phone.
I bought Flex cable on ebay and IT WORKED!!! Yay, but now I'm experiencing some problems with usb connection
I changed the housing of my TyTn II because the old one was really worn.
Now when I have a brand new housing, the internal GPS is not working anymore. So I'd like to know where it's located (physically) in the phone in order to check the connection/replace it.
Thanks a million in advance!
Either way you're going to have to take that thing apart again lol...not very fun
I believe the rear speaker housing doubles as wifi and gps antenna, underneath the speaker housing there should be 4 gold plated contacts, which connect to the mainboard by 4 matching gold plated spring contacts, ( 2 are close to the camera, left side, and the other two are on the top left corner by the external antenna connectors).
It's possible the spring contacts have broken off, or got trapped when replacing the rear housing, they are rather brittle, if they are broken then your probably looking at a very difficult repair, since the only way I can think of is to find a dead mainboard and desolder the connectors, and transfer them to your mainboard, if they are trapped then maybe you will be able to straighten them, but this may break them anyway.
it's also possible that the speaker housing is just not fitted properly at the left side, and this may be enough to prevent the antenna from getting a connection.
I'd remove the screw beside the camera, carefully remove the speaker housing, and have a look, (if you got a new speaker housing try the old one as well ).
gps antenna should be located near the usb connector either to the left or right.

you can look at http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=3540022&k=gps antenna&stock=1
sometimes the GPS will need sometime to recalibrate after being off the batt during repair..

Just bought a new screen for a cracked hd2 and hit some problems. Firstly, its a uk hd2, so it was a solder connection, i bought the screen + digi from ebay and noticed it was a ribbon connection (not sure if that will make a difference). When undoing these plastic clips
http://imgur.com/Faiyig3
Both broke. They were so brittle, has anybody seen/heard of a way to fix this? I put it all back together and the screen does come on, but touch doesnt work.
Can anybody tell me what these cables do? Is one for touch, what about the other?
Gutted about my hd2, its been going so well all these years...is it fixable?
Not good :-/
those 2 clips: one is the flex ribbon connector & other is the LCD ribbon connector.
The ribbon from LCD also is feed for digitizer.
Not sure if the locking arms are replaceable by themselves ! will look at an old mainboard & see.
you may get some function by bending a very light V in the ribbon so point of v is ribbon contact face & thus pushes tighter in socket promoting better contact.
putting a bit of tape on back may help too! be careful though as actual socket is very fragile too ...

Tell me about it, thanks for explaining what the ribbon connectors do...I couldn't understand why the screen would turn on if the connector was broke. That's a good idea about slightly bending the cable, I will try that tomorrow afternoon. If i could swap them out, that would be awesome.
Thanks for answering, I appreciate you talking time to help a fellow hd2 fan!
Have made none working digitizer work via creating very light v shape bend in middle of contact area (bending across width of cable)
Do be gentle though ... not sure how successful it will be without clamp though :-/

how did they break? i'm going to attempt this myself soon and would appreciate any advice on getting the clips open safely.
I was recently reassembling my Note 7 and managed to get the antenna and/or its connector (main, upper motherboard) twisted. Thanks to the quarantine I can't easily get another antenna, but even so there's the possibility that I also need to fix the connector. How can I do this? Do I need to solder it? Thanks.
