XDA exec connectors? - JASJAR, XDA Exec, MDA Pro General

Hi,
Iv been watching these forums for a while and have had a xda exec for over a month. I like the device except there is something which has realy made me wonder something. I cant find the answer so i though somebody might know the answer to my question.
On a xda exec, on the back of the device where the usb connector is, far left to that is 2 rubber circles. I'v taken these rubber circles out and there is two gold connectors behind. My question is what are these connectors for?

for the gsm and umts antenna

Scary,
About 30 min ago I thought the same...
Maybe ext antenna?
Edit: Thanks decebal...

definately true... have a loom at the service guide for more info

so any way of making a home made antenna to fit in there to boost up signal?
I know the universal is not too bad signal wise but where i work i can hardly get a signal

Is this the antenna?

If you remove the battery cover, between the speaker and camera, slightly towards the top of the phone, there is a zig-zagging line. Is that the phone antenna? Or possibly the GPS antenna?
Reason I ask is that many years ago, I bought a bunch of those little gold stickers that are supposed to boost your reception. Though i dont believe they work, I have them, and figure it cant hurt to stick one on over the antenna.
=) Silly, I know...

Honestly, I am not 100% certain, but it could be the radio antenna and not the GPS... you might as well try it. I had one of those, and I think it actually made things worse when I put it in my old Nokia
LOL. really? I'll do some experiments. 5 days with it off, and then 5 days with it on. We'll see how it works.

According to these references
Not in english....... completely... but list an antenna assembly #20 onpage 24...and pictures [of that part number] on pages 11, 16, 27

Boosting signal easily

In brief it works.
If you look at Note stuff on ebay like me then perhaps you have seen those signal booster things. Looks like a sticker. Cause it is!
Ok it looks like crap. But I know that putting in an extra antenna could help if its then able to also transmit what it receives. Don't know enough to know for sure...
But for $2.90 I decided to try. It was a small metalic sticker that arrived. Instructions look like they were written 10 years ago for phones with antenna poking out the top.
Having seen teardown pics of the Note I figured out the antenna is on the bottom below the battery. I was at a hilly farm where there is only one tower and positioning is both sensitive and predictable. Perfect for testing.
I put the sticker over the antenna and was surprised to see it dropped the 2 bar HSPA connection to a 2 bar GSM connection. Putting the phone where I could normally get 3 bar HSPA was a 2 bar HSPA. Ok this confirms the sticker does actually affect signal. Now to place it correctly.
The instructions suggest placing behind battery in the same direction as antenna. I don't know if top should face left or right but I put it there.
Signal much better than first test and better than control. Able to get 1 bar in many places which was 0 before.
2 bar HSPA became 3 bar HSPA and 3 bar became often 4 bar :-D
I've ordered some more so I can experiment with orientation and also try multiple stickers.
It was worth $3 !!!
Measure dBm for us please
Could you give us a link to which one you bought and also some pics of where you installed it

plz post pics when you are finished with testing so we can see exactly where you put the sticker.
I bought one of these myself. from the tutorials Ive seen its seems that it must be placed on the antenna itself. & Notes antenna is placed inside the back case, so it has to be opened by unscrewing all those philips screws inside.
how about a link so we could all have a look??!!cheers!

haha that's funny! I got a pack of 25 of those for like 10 euros about 5 years ago. I still have them around in some box. I guess I'll try it some time
measurements with and without please
I'm pretty sure that if you could boost your signal this easily and cheaply then phone manufacturers would just put them in the phone in the first place!
Allow good ol' Jade to bless you with his gospel of sensibility and reason:
It's snake oil folks.
Think about it... I have seen and used these little stickers in the past before, back in the old days. Supposedly they work using harmonic resonance attenuation. However, even if you make the signal appear to be stronger, you have to remember that there is a very big difference between signal strength and signal quality. A strong signal doesn't automatically mean a good signal. If anything, the little thing is creating signal interference which will hurt your overall performance, despite the extra bars.
Besides all of what I just said, don't you think that, if it's so cheap and it improves signal performance so well, Samsung would have included it in its original design?
Go buy a cheap beer with your $3. It'll be better, trust me.

I'd be curious to see if there is/was a way to boost the antenna signal. Kind of like how you can on wireless routers with modded firmwares.

I'll install that and give it a go later in the week when I'm back on the farm. I've ordered more of these stickers. If the new ones arrive in time then I'll happily do before and after dB measurements.
Here is someone selling 5 on ebay:

take my apologies in advance, but may you be interested in my new "dr.tml's new lifetime enhancer" as well?
this sticker (genuinely invented by me) will boost your life expectation at least by a few % by absorbing, amplifying and sending your bio energy back to you! especially usefull if you have some sort of disease...
i'll sell this "dr.tml" stickers for USD 10 pp, cash in advance!
if anyone is interested please let me know, i'll be more than happy to deliver!
ps.: soon i will have also the "dr.tml's new lifetime enhancer V2 ultra" ready!
the advantage of this ultra new sticker would be that it could separate between good and bad bioenergy, and thus only reflect the good-one to you! stay tuned...

HTC HD2 High-definition Motherboard Pictures

Hello guys. I need high definition photos of HTC HD2 Motherboard. I need to check one SMD part on motherboard because I think I accidentally broke one part on it. It seems like there is one missing part but I am not sure. So if anybody can upload really high def photo of motherboard it will be great. I searched google and forum here but its not enough to zoom in on that place.
This is what I had laying around

Don't mind the black stuff, I used a marker to mark this bricked mainboard
Sent from an awesome HD2 running Hyperdroid in a galaxy far far away
i am sending a pic of that place. its a small smd probably but i am not sure . the location of that part or better say place is very near to the edge of board it is the last solder point to the 3 gold connect points i am not sure for what they are used for. probably for extended battery? i just need to know if there is som smd part or not. because it looks suspicios on my board and i think that this is why main speaker is not working on my hd2 since i disassembled hd2 to repair vol buttons. flex cables are ok i already checked them because i remember when i bought phone the sound was not working because main flex was not properly pluged in on main board. i was very careful whem i was dis and assembling phone . i dont understand why aound is no longer working.
Nah there is nothing there. At least nothing that can break off easily. I'm sure the problem is somewhere else.
Is it the earpiece not making sound or is it the speaker on the back?

Well the problem should be near the GPS board... Or in the rear shell....
check this: (No need to take the speaker out) http://www.ifixit.com/Guide/Installing-HTC-HD2-PB81120-Phone-Speaker/5605/2
And this is where it connects: http://guide-images.ifixit.net/igi/IKePYgHa1GxX1vZF.huge
It's left from the camera, between the Camera module and the where the white wire connects to the board. There is should touch the 2 golden squares.

i will check that place near gps. Or maybe the speaker is broken. I will try another one if that help. I will let you know later when i fix it. Thank you wouternet.
Sent from my Dorimanx powered HTC HD2
Well you was right about the place near GPS where speaker is connected to the phone. The problem was there. For some reason one of the golden square dont work anymore lol. Weird huh. So the solution I have found out was to connect that non-working golden square to the little golden O point between those 2 golden squares.
Here is a picture
Selected red places are the points that are working.
So i connected non working golden square to the O point between those two golden squares with solder and after that woalaa. Speaker is working.
I still dunno why this golden square caused the problem because it looked like it is solidly attached to the board. But anyway speaker is working and I feel peacefully .
I will edit this thread as a guide if somebody needs it. I also fixed camera flash light because everybody who dissasembled HD2 know that cable from camera flash light connected to the mainboard is very fragile and it can be easily torn out of the connector and if you want to put it back into the connector it is really painfull and not always work so I decided to solder it to the board on camera flash light.
Here is a picture how I did it.
I connected those coloured cables using solder to the golden O points on camera flash light board as it is shown on the picture. Woalla again it works. Its free if you have soldering tools and some experience with soldering .
Thanks so much for sharing your solution.
Exactly this hint has given the life back to my phones speaker.
I used very thin copper wire to connect the 2 points.

Wifi antenna

This is my first post here, so I hope you will be patient with me. My wifi on my Acer iconia tab a500 has been poor no matter what from I would flash. Today I decided to try something. I went to a friend who works on laptop computers. I got two antennas from him, which have the same connector as the one in my tab. After installing it I am getting two to three bars, where before I only barely got one. I will write a install instructions, and post some pics. I am very pleased with my wifi now.

I don't have a part number, he just cut them from the laptop he had apart. I checked at a computer store the other day, and was told they cost about twenty bucks. I will ask my friend if he can get a part number. All I know is that after I put it in my Acer tab a500 is getting on internet a lot faster.
The Antenna that i used is from my old desktop i just cut the metal part (the flat with circles) to fit it to the side of the tab..
Again i did numerous of try and test using WIFI analyzer from market to position which is the best loop/setup/placing to get a better signal again my wire is long and i don't have a short one i don't want to cut my wire short but i don't know what setup is best for you and your router mine is E4200 here's a couple of pics i took hope it will help.. so far i haven't been/experienced any slowdown or disconnection while doing that mod..
You folks should check the Transformer Prime forum. Those users came up with some very clever ideas on improving the Prime's Wifi when the first editions were released.

Well, there were a ton of images in several post's, and it was over a month ago when I saw them. Some of them, it appeared they got some wifi router antenna's, drilled holes in the back cover, and attached them for Wifi and GPS!!!! Looked like martian spaceships!! One actually had 3 (bluetooth?).
Another idea, for the 500, is to route a longer cable antenna through the fake 3g Sim slot and affix it to the outside of the cover.
All of them claimed their mods worked fantastic! You just have to root through all the posts to find them.
wifi antenna
The tab is still running at two to three bars while I am in my bedroom. I have included some pictures if they come up right. I don't have a serial number for the antenna, as my friend cut it out of the laptop while I was there. The laptop was a HP. I do not have wires running around the outside, nor does it look like a martian spaceship. Draw your own conclusions from the photos. I believe these antennas for laptops run around $25.00 here in Colorado Springs. I don't think you need the attached tiny circuit board that is on the old antenna. Everything is still running good. Hope you enjoy, and hope I have helped. This worked for me, and I have a $40.00 Dlink wireless router in the living room. I have the pictures on my computer and can't get them to this post. Try latter this evening. Well it looks like they poped up after all. Enjoy.
I believe this is the mod moscow was refering too, about the space ship like look to it. Im about to just stick the antenna through the sim card slot and just keep it in the case this should be epic

Thanks for posting the pics. Could you identify exactly where the laptop antenna is in your 3rd and 4the photos ? Thanks.
Wifi antenna location
I hope the enclosed picture will help. If it doesn't then let me know, and I will make a video. If the circuit board from the old antenna is important, I will probably build one after payday and see if it does better. Right now I have no problems at all, and it was $0.00 cost for me.

Poor Signal after Replacing Digitizer

Originally I had great service 3-4 bars continually, I dropped my S4, got a small crack it, tried to replace just the glass screen and I mistakingly hit the digitizer and had to replace it. I replaced the digitizer and have the phone on, however I am barely able to make any calls now. In the last 6 hours I was able to make 1 successful call. Even wigle wifi where I would usually see ATT at around -103db is showing -110db or not showing the ATT signal at all. Even going down to where I know normally I get -59 db to ATT I am getting no signal or in and out signal.
I have tried to swap out the internal antennas.
What is suggested? I have obviously turned the phone off and on multiple times during the last 6 hours, so something more informative than the basic, please....
Where did you have the digitizer replaced?
Where did I get it from?
I replaced it myself. It was a very simple replacement, but I do not see what role the digitizer would play in the signal?
Just confirmed even being less than 100ft away from a tower. I have no bars, previously I had 5 bars in the same area. It fails to register on ATT as well.... seems something is funky with the radio or antenna. I have swapped out 3 antennas of different length, all giving the same results.
It must be the schematic of this board. It is for sprint, not ATT. Although the PCB has the radio on it, it seems like the bottom of the attachment has 2 separate antenna connectors where as my PCB has one.
Odd. Very Odd! I am going to grab a I-377 one AT&T logo and see if that helps. It is something with antennas because even when I remove the antenna the signal is identical.

Same problem with the GSM version of the Nexus 7. You can use the bezel from the 32 GB WiFi model, but it won't have these special little contacts needed for the radio to work property. You need the AT&T parts. Always get parts specifically for your model number.
