HARDWARE problem,help me ç_ç - Atrix 4G General

http://www.youtube.com/watch?v=TbR56jSplRs
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 !
It is not a problem for me.

Rotating mechanism is broken - PLEASE HELP

Hi, everyone i am so sad you can't imagine . The rotating mechanism, the metal part which rotates the display is broken. Don't ask me how, i don't know.
I do not have any idea what to do now. Where to find, how to search ont the WEB. Is there anyone who had problem with the rotating mechanism? Could you tell me who to ask to replace this part? Or does anyone have a not working Uni....i would buy this part from them
Hi,
Dont be sad. Try to find parts on ebay. I saw there thaat part along with wires connecting LCD. It costs few bucks.
it's also surprisingly easy to open the hinge up; unscrew the little screw in the metal base plate. It's metal on metal so no risk of wearing out the screw. Base plate comes off and exposes a single cable that's well protected; no risk of screwing this up. Now you can take the plate and get a new one manufactured at any metal shop or anyone with an interest in metal work. Even a jeweler I'd guess. You may even find the plate is just bent a bit.

What are the metal pins that connect to the battery cover?

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.

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*

Desire HD GPS Fix

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:
Nice
Sent from my Desire HD using xda premium
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

It wasn't too hard to take apart, only hard part was removing the back glass, took some work and heat. You don't want to rush it so you don't break the glass. Don't think it would be possible to take it apart from the screen side, the cables are all connected to the main board from the rear so you would need to take the back apart regardless to get access to the connectors.
Im impressed by how clean the device is inside, unlike previous devices (10, m8 etc) that all was a PITA to tear down with ribbons going through the mainboard etc.

U Ultra was pretty clean as well, HTC must have learned quite a bit about internal design from being an ODM for the Pixel )
great video as always.
Looking at the mainboard from the front of the phone, what is the little block next to the "selfie cam"? Is that another mic directly under the pinhole on the top of the phone, or is it part of the speaker/subwoofer?
I only ask because I accidentally tried to pop out my SIM tray by putting the needle tool in the wrong hole .. There was resistance, and then there wasn't. All mics seem to be working. Max volume of the phone seems low, but I could be wrong. Did I just destroy the top speaker assembly?

It's another mic hole (for the video recording audio feature). It has a fine wire mesh going across (slightly recessed under the glass) for extra dust protection. You only just pushed through that so may not be as dust resistant as before.

Thank you both. I'm not as concerned about the IP67 water and dust resistance, as long as I didn't just skewer the speaker or sever some important wire.

I need to remplace my screen, It's broken but functional, but it isn't in the video. Can you explain me a little more, how to remove it safely? Please
Yes I would love to know if the glass is replaceable from the front without disassembly....... Smaller quote I have gotten is $320aud using htc parts (they won't consider using aftermarket which I can get for $40aud)
The digitiser is fine....... Can you please pm me if this is possible? In theory it should be the same as removing the rear glass and as you are not disconnecting the digitiser from the board.
I'm inexperienced here so please correct me if I'm wrong
---------- Post added at 01:06 AM ---------- Previous post was at 01:03 AM ----------
Or is the screen and digitiser one complete thing
Unfortunately you will have to start from the back if you want to remove the front LCD. The LCD cable is located under the battery so in order to remove the LCD you must do the following:
-remove back glass
-remove protective black panel
-remove speaker on the bottom and lower board
-remove motherboard
-remove motherboard
-remove lcd
I would go for a replacement part that comes with frame rather than the LCD only. You just transfer from old frame the motherboard and the charging port, the earpiece and the speaker and the battery.

I've just got mine apart to look at doing a screen replacement. What do you need to do to put the back panel back on, glue/tape?
Unfortunately all these teardowns to be found in the net do not mention ot show where the gps receiver is. I have to replace it as it is not working anymore (after several weeks of increasing location deviation.) I would like to replace it, however, I couldn't find any hints regarding the make or any other specifications.
Any advise is very much appreciated

G900F R1 / R2 antenna help, broke off R2

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 )

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.

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.

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.
