Hello people.
I was busy repairing S5 and by curiosity I removed the R2 port and there in one antenna was stuck, it popped off the motherboard and I cannot find it anymore.
Someone suggested (https://forum.xda-developers.com/showthread.php?t=1625663) to stick a small copper wire and to tape it down, would this work?
see picture...
There was nothing in the bigger connectors. Antennas are in other place.
Do you mean a small round grey plastic cover? Just forget it.
Or the whole connector is torn off?

As seen in picture marked, the whole connector is torn off. In the link you can read that it's necessary for signal reception.

These two (bigger) connectors look like test-points or something.
I'm sure they are not necessary for signal reception.
But if you have a closer look at this place, you'll see a PCB track running under that torn off connector (please refer the image attached).
If this track is untouched, the phone will work as it should.
But if it's damaged, you'll have to repair it. It can be done with a thin copper wire and some soldering (no tape )

only the r2 big connector popped off.
I hope that LTE will work otherwise my friend will be pissed off. haha.

I've looked at your problem once more.
I'm sorry, but it looks a little more complicated than it was before.
Please have a look at the pictures attached.
I don't know what variant of SGS5 you have, but you can probably see something like the image on one of the photos.
If so, you'll have to connect by soldering the points circled in red.
That's because the port or connector which was torn off worked like an electrical jumper between these points.
Good luck.

Thank you so much. I can use copper wires?
I don't have to connect the sides, just connect point a and b, right?

You can take a common stranded wire and take one thin solid copper wire from it.
You can solder it without problem because the green substance on the PCB is insulating coating, but the points which you need are free from this coating.
P.S. No, you don't need to connect sides - it's just "ground" and they are still connected.
Just connect two points circled in red - it's the signal line.

Thank you so much! Tomorrow another friend (specialist in soldering) will come, and I will ask if he can help me with it ^_^ Just a very thin copper wire, it should be possible
I tested it broken like this and I notice the signal is very bad, 0-1 bar.

You're welcome.
Let's see if it helps. I think it should.
Just to make the things more understandable.
1. Get a piece of conventional stranded wire (1).
2. Get a single thin conductor from it (2).
3. Solder in the jumper very carefully and get the result (3, 4, 5)
P.S. All photos were taken with Samsung Galaxy S5.

I've fixed an s5 via this method. It does work. There's all kinds of crazy things that fix issues but sound ridiculous. I fixed the motherboard of my ps3 by wrapping it in tinfoil and baking it. Seriously. It did a reflow of the solder.

Do it properly, forget the tape. Actually solder the wire onto the two points. It will give much better contact

I have an XDA Neo whose soft buttons haven't been working for quite a while and I cannot find a right moment to send it for repair. But I suspect it's the dust that has made its way beneath
But the bolts are so strange, I cannot unscrew them with anything - screwdrivers, knives I tried - nothing helps
Any suggestions?
this is easy you need a torx 6 screwdriver good luck
10x a lot
Look no further..
http://www.modaco.com/Changing-you-prophet-caseand33-t240109.html
Attention to side plugs...
Yes that's torx 6. It's rare but available in some stores.
But it's not over. There are some steps which need special care. Otherwise you may break some fragile parts of the body. I dismentled 2 times completely but i broke some plastic ears on the sides and the screws are not enough to come back to a tight fixing. Some spaces remian on the sides if you break the small ears while disassembling.
The steps, roughly:
1- Pull out battery, sim card.
2- Unplug upper rear cover (not necessary to unplg the antenna cover) starting from top, then bottom. Pushing 2 ears at left and righ side of the bottom is enough.
3- Unscrew 4 x torx6
4- Pull out front frame by unplugging side ears surrounding the whole frame but PAY CLOSE ATTENTION TO KEEPING THE EARS UNDAMAGED. The frame is still connected to the board and the speaker. So separate it slightly, not too much.
5- Unplug the speaker unit by pushing its caoutchouc frame and slide it through the hole to free the rear frame. DO NOT ATTEMPT TO DISCONNECT THE SPEAKER SOCKET. IT'S DANGEROUS AND NOT NECESSARY.
6- Pull out the camera. Its body is not fixed but only pushed into its frame. Pay attention while disconnecting its cable.
7- Unplug the keypad socket by pushing upside from sides. It's fragile but not too difficult.
8- Unscrew 4 little screws. One may be masked by a spacer. You can push it the access the screw.
9- Unplug the AC connector if necessary. Not screwed. So, you can get manually.
10-Pull out the keypad towards the rear of the phone. It will not come very easyly. Find the right angle. It's not necessary to pull out the white cover but you can do this if you want.
I write this using what i remember. I may forgot some small details but the order should be correct.
Finally don't use battery screwdrivers on a/m screws. The torque will be too strong and may destroy the plastic holes. You can unscrew but don't screw.
Thanks a lot man. I know it's dangerous, so want to be extremely careful. But some people told me that doing this can break my warranty because some of some manufacturer sticker being damaged. Is that true?
Yes, Warranty Voids If Dismantled
Yes indeed. One of 4 torx screws is covered by a warranty label. You have to destroy it to unscrew.
I did it because i never trust warranty issues on PDAs, at least in my country. Mine was fallen on its upper left corner and the body has taken a good crash make-up! It's 100% sure that u have no warranty because of user fault.
So, i dismantled and tried to repair the cover like a garage man works on a crushed car. Result: Not bad. Better than nothing. Some painting has gone. I add a silicon case on the device and everybody's happy.
Hi. Can anyone help me identify where a part comes from? I took apart my Prophet because of the amount of dust it in and the very irregular digitiser calibration. This is much better but I seem to have a piece left over and I don't know where it should go. I think it must be something to do with the phone antenna as I have very poor telephone reception since.
can u post a pic of the top end of the circle? can't really make out what it is. didn't have this problem when i opened my case
Hi, thanks for taking an interest. Here's another couple of shots.
Richard
i'm kinda guessing that it's the external antenna? u know the 1 with the rubber circle at the back of the pda? can't seem to find my tools atm to see what it actually is...
Yes, I am sure you are right - I will get my tools out and have another play with it. I may find an obvious place where the antenna goes which will fit the part in.
Well I feel pretty silly now. I took the Prophet apart and realised that this part was just a mount which the long screws screw into. One mount had come loose so I superglued it in and the screw firmly screws in now, making the whole device hold together better.

Ever notice how there are two metal pins on the back that make contact with the metal cover? Why did HTC put them in there?
Also would one be able to hardwire the antenna too these points so that the metal battery cover can be used as an extended antenna?

They are probably there to cushion the force of the back place being clicked on.

Not a chance, have you ever pulled a HD2 apart? I severely doubt it is a wise idea. Hardware modding of a phone is a fools game.
Is it to dissipate heat?
It's for the car GPS kit.

Not the 3 pins, the 2 balls on either side of the phone.
Is it really for a GPS kit? Maybe that concept kit that HTC never came out with? But what would they do it can't be for power.
Sent from my HTC HD2 using XDA App
This comes up every month or so, and i agree with Kalavere in that they are there to keep the back plate snug. They are spring loaded, so the plate wont get wobbly with extended clicking on/off. Since the reset button is under the back panel, it seems reasonable that HTC would expect the plate to be removed fairly often.
I also think it plausible that they are earthing points for the antenna, but i think that a little less unlikely.
Not sure exactly what they are for but I am positive they are not there to keep the backplate snug.
They are some kind of a contact point. The metal cover bridges the connection. You will notice that the cover is clean where the points contact.
Never seen the car kit but that is a possibility. I doubt very much that they have anything to do with the antenna. My guess is that they might simply be a ground shield.
I had the same question, I rung up the HTC support here and they told me that even they are not sure, but they did mention that on the inside, it's linked to the antenna for the GPS. Don't know what they mean by that but I guess, it's either an earth (since, if you notice, the area where the nobs rest has the paint scrapped off), or the whole back plate is an antenna. I tried to insulate it, no diff to operations of the GPS or Phone.. *shrug*

Hi,
I disassembled my N1 for changing the main flex cable (cutted power button) and in the disassembling procedure I noticed that one of the SMD components on the motherboard was de-soldered or not correctly soldered (twisted). I re-accommodated with a pair of tweezers and it did not hang loose (yet!).
What kind of function does this SMD do? Can I expect the phone to work?
I have experience with soldering iron but think this is too small for me.
I can't test it right now because my new main flex has not arrived yet.
Maybe you can solder it with an oven for CMS ?

I'm not very familiar with oven soldering; dunno if I will kill other components or If i need some kind of flux.
Also a heat gun would do the work but probably desolder other components.
I broke off a couple of the smd components right next to that connector (the screen connection) they effect color on the screen. Mine showed only red after I broke 2. It was usable but not pretty.

Thanks for your answer.
You broke those very same components?
As soon as I get my main flex i will try it and see if it report problems. It probably will as that component is there for something.
You might be able to re-flow it with a heat gun.

Actually I'm looking for a chinese reflow station with a hot air gun with a tiny nozzle. Probably will do the work but...
Should I use some kind of flux? Any recommendations? Never done a hot air reflow.
Looks like the same but hard to tell in the pics. I can't really see on my phone.
Sent from my HTC Desire using Tapatalk
that is a set of inline resistors, meaning it is quite a few connections, the best way is to use some flux from a needle and a soldering iron with a small tip,you could use a hot air machine but on a fully assembled board i would not recommend it.. flux is needed but you may be able to get away with a large soldering iron.
My advice would be to pay someone to fix it.. that way if they mess up ya get a new phone
Find someone with a reflow air knife, anyone who does SMT work would have one. It'd take 5 seconds to put that RP back on as long as you didn't break any of the pads doing whatever it is that you did that caused you to break it. Yikes.
May i ask you where u got the power cable? I need one too, how much was it? And is it hard to replace?
N1
I bought it on www.aliexpress.com
It was around USD$45.
I still don't receive it, as soon as I recive it I will report if the phone works and if it is an easy repair.
Best Regards.
The phone it's not turning on.
I tried it disassembled with the new main flex cable, motherboard and only lcd conencted.
Nothing happened when I press the power button.
The only sign of life is the ambar led that turns on when you connect the charger.
The tiny little SMD part fell off the mother board so it is completly unsoldered. Could this be the cause of not turning at all?
Looking forward to your answers.
Yes, if a single component is missing or even has a bridge in the solder, it could cause complete failure. There is a reason for it being there. If it were me, I would try to resolder it. Grab an iron and some wick and get what you can off of the board. Then try to reflow the part back on. If it works, great. If not, you still have a nice looking paperweight.
Well, I soldered the little SMD back with a soldering/hot air station but the motherboard still don't turn on.
It was working before, maybe I'm doing something wrong.
Thanks for your support.

at 6:34 the guy touch a copper piece that is glued on a plate.
I've bought an atrix and in my phone that thing is sliced.
it's a big problem?it's front camera or speaker piece?
Hi,
If it's in copper, I think it's the ground for the top PCB.
It's better if you can found a way to keep it connected.
But it's possible that work sliced, it depend of the drawing of the PCB...

it's half conncted..so there would be no problem if a part is connected to the plate?
Put a small sheet of tape to fix it and go head !

After having no GPS for about a year and getting annoyed with it not working I accidentally found a post about soldering wire to the contacts.
Well, rather than soldering I wondered if I could make a little tin foil antenna. Works a treat!! Pics below:

Seems like a great idea,, much easier than soldering,,,, did you sandwich the foil between two pieces of paper ,, was it easy to clip it back together with this mod.
Very tempted to try it.
hi,im struggling with enanche GPS signal too. just two questions..is it just aluminium foil ( http://upload.wikimedia.org/wikipedia/commons/1/12/Folie_2007.jpg ) or some other foil? and behind,is a piece of paper to cover motherboard contacts?
thanks in advance

Any conducting foil should be good enough if you ask me. But look at other threads - about resistance/lenght of the antenna etc. - this one is quite a guess, but should be better than not having antenna at all. By the way, if you have broken antenna (the cover), you could apply this patch to the cover leaving the spring contacts to do the resto fo the job.
And more... A new cover (antenna) on eBay is about 6 pounds? (10 euros?) - is it worth of making this by yourself when you can get a new cover?

Template
Is it possible that you could upload a folding and cutting template? Also, (and I believe it was mentioned a bit back) it appears that you have a piece of paper behind the foil to prevent accidental contact with the board other than on the antenna points. Would something like this also work on the other antenna points?
Nice idea .. but i am afraid of shorting motherboard contacts... Perhaps any more detail from you in the long run would be appreciated...
Also my spring contact broke as soon as i tried to pull it up. so may be soldering a wire would fix my GPS!!!
Tried this. It helped a little but couldnt get a good connection and as soon as i moved the phone it would go
probably try to soldier a wire onto it

Damn, sorry I missed all the replies!!!
So to make the template I used a craft knife and a board and trial and error cut the paper until it fitted correctly, once I have that done I used that as a template to make the foil.
I used the paper to prevent the foil from touching the motherboard. Its just regular kitchen foil.
To remove the cover I CAREFULLY used a razor blade to lift the side of the cover closest to the camera, its very tight the first time you try and open it, once it been off a couple of times its really easy to do.
To update this methods results, I found it worked for a while but then I started having GRP issues again. I was going to solder a wire in the instead but was due a upgrade so ... HOX ftw.
Soldering a wire in there would be pretty easy using a fine tip on a gas soldering iron, may be a bit more fiddly with a regular fixed bit electric iron but certainly doable. This would be a better fix, though have a look on fleaBay, it may be worth trying a new GPS cover ... I'm certain the issue lies with a really ****ty connection between the motherboard pins and the antenna points on the back of the cover and nothing else.
Sorry again for the slow replies guys, I posted and set for notifications and then forgot about it, was only by chance I found the notifs in my spam folder.

EDIT: Please dont jump into conclusions too soon as I did! At first I thought tha this fix was working 100% but I then noticed that although I (at last) had a signal it was too weak compared to a 'healthy' gps receiver and the phone lost it as soon as i got in a moving car or changed direction.
I used tinfoil from my kitchen, plain printer paper, a pair of scissors and a cheap modeling knife. I used the 'trial and error' method just like you said and cut out the paper for insulation first. I trimmed holes for the two flash leds and the strange circular part right next to them.. I then cut the tin foil a tad larger than the papers area and I folded its edges all around to keep it from falling apart.
Congratulations for thinking so cleverly. Thank you for uploading and sharing this fix.

EDIT: My spring contact also broke apart but it seems to have little on this fix. If the tinfoil has enough width then it should lie correctly on what remains of the broken spring on the main board. The problem is that after a few days the tinfoil looses some of its width due to continuous stress that we apply on the phone (while holding it or having it in our pockets) and thus loosing contact
