I don't think that's even possible since one is sense and the other is aosp.. and I can say this cuz I try getting the miui file explorer to work on a sense ROM without success...
[Droid Incredible Q&A, Help & Troubleshooting] sk8erord:
Yeah, I can see that being the case, though I'd half expect to be able to get AOSP to work in sense, but not the other way around... *shrug*

Bah, I'll mess with it a little more and see, but I'm losing hope. :P
[Galaxy S II General] kingqueen:
I have been attempting to use the antenna socket located under the battery cover on my S2. Sometimes I go to a very remote location for a week where I can only get reception via a amplified Yagi pointing at the nearest transmitter (Orange only as well, no other networks for miles.) I currently use a P1i for this as being dated it has an antenna socket.

I wanted to do the same with the S2. I was very excited to spot the antenna socket under the battery cover. Much research online doesn't really give much information about it; neither did a phone call to Samsung (who were unhelpful.) Some online shops in Australia sell a constructed link for it but nobody here in the UK does, as far as I can tell. So I was looking at creating my own pigtail lead.

Having difficulty finding what precisely the socket is, (it isn't an MCCX I can guarantee, others report it isn't an MCX) I took a thin wire and pushed it into the centre to see if I could bodge a connection together.

Big mistake! The external antenna works - but now the internal connector doesn't. Whenever an external antenna is connected it disconnects the internal one. It turns out that if you use the wrong side wire, it appears to force apart two contacts within the socket (best I can tell with my loupe) and the internal antenna never works again.

I suspect the solution for Galaxy S which sometimes had a spontaneous similar issue - removing the antenna socket and shorting the contacts - would work, but it's not at all simple to do especially given the infrastructure on the other side of the PCB.

People think that this socket is only intended as a test point for use by Samsung before shipping the phone. I would strongly suggest NOT MESSING WITH IT or using it - and if you do, to buy (import if necessary) the specially made cable. Otherwise you may suffer my fate and have no internal antenna connection any more.

Beware...
[Galaxy S II General] mwhincup:
Thanks for the info.

I'd wondered about that socket...
[Galaxy S II General] silk_nz:
Maybe pushing the same bit of wire back in would again bridge the contacts and give you your internal aerial back? Snip it off just above the socket?
[Galaxy S II General] kingqueen:
Thanks for the excellent helpful suggestion, regrettably it doesn't work though. The little bit of wire itself works as an antenna but it doesn't reconnect the internal antenna. I think this is by design: pushing a pin in should disconnect the internal and connect the external, sadly in my case whilst it did do this the wrong diameter wire stopped it going the other way!

Happily good news: I've negotiated a warranty replacement, doorstep swap for a new one. Thank you O2.

Additional info for anybody thinking of trying to get a connector for this socket: having received an MCX connector in the post today, I can confirm that both MCX and MCCX connectors are definitely not compatible with the phone's external aerial socket and can't be bodged to work on it either.

Elsewhere forum contributors state a Samsung tech told them it is an "MPX" connector. The only MPX connector I can find on the Web is something entirely different, not for use with mobile phones.

What a mystery

Thanks once again
[Galaxy S II General] n-zocker:
Guys, do not touch that Socket!

I did the same and my s2 is now at the servicepoint!
[Galaxy S II General] kingqueen:
sorry to hear you've had the same fate as me!

Did you use the official patch lead e.g. www.cellink.com.au/productdetails.a...d=WES1781263914N&pcr=WES596880305N&byp=2&qf=1 or try to bodge one like me? I've ordered an official one but think I'm too scared to use it, having broken one s2 already!

Further info, it's an MS147 connector.
[Galaxy S II General] LBTaylor1984:
being that its under the battery cover, with no opening to the outside casing I would assume this to be a Manufacturer port only. and therefore shouldn't be used, nor played with.

I appreciate your efforts and troubles but sometimes you should leave these things alone, is there not a solution that doesn't require a connection?
[Galaxy S II General] n-zocker:
nope i broke mine with that "wire method" ^^

i will touch that port never again :)
[Galaxy S II General] Archer:
What, like the microSD port, and the SIM slot? ;)
[Galaxy S II General] kingqueen:
Not really! Passive antenna couplers don't work. I'll have to go back to my p1i with its antenna socket and Sony Ericsson antenna lead, obviously designed to be used. Old skool! Even then I can only get signal on one network, amplified using a vehicle pcs amplifier and using a directional Yagi...

^^^ cos my SGS2 is dead and not swapped out yet :-(
[Galaxy S II General] boxhead72:
I did use the Cellink connector and it killed my internal antenna.

I asked about this and was told they checked with Samsung and the port is ok to use. Sounds like a design problem but will wait and see what the service centre says.
[Galaxy S II General] Entropy512:
What about active, such as those solutions from companies like Wilson?

I have had excellent results with their vehicle amplifier kit here - http://www.amazon.com/gp/product/B0011GI94Q

However it sounds like you'll need significantly more "oomph" - probably one of their higher-gain building-oriented kits, with a cradle and a Yagi.

I believe their non-direct-connect amps have the gain increased to compensate for the losses of the phone coupling.

Galaxy S (i9000T), same problem here

Hi everyone. I have a SGS i9000T, had the same problem as you guys.

I was in a rural area (Brazil), and it's very common there to use external antennas (by very common I mean, it's the only way to get a signal). My mother-in-law has cheap cellphone for this and I tried to connect her antenna. I has not only worked like magic, but also all the area suddenly had wifi internet access!

But after I had disconnected the antenna and traveled to the civilization again, no signal, just like happened to some here. It happened *exactly* the same way with my HTC Touch (GSM). At first I thought it was a problem with the phone, now I see it's the same connector.

The fun thing is, yesterday I went to a Samsung service center and there was this poster with tips for your phone (like, how to backup phone contents, how to clean it, carrier block matters, etc), and there was it, with huge letters: "DO NOT CONNECT AN EXTERNAL ANTENNA TO YOUR SAMSUNG PHONE. IT MAY STOP HAVING A SIGNAL AND IT WILL VOID THE WARRANTY." Well, actually, it was in portuguese, but that's what it said. It's like, "yes, we know there is a MicroSD slot in your phone, but no one said you could use it, now your warranty is void"!

My phone was not under warranty anymore anyway, so I'll try the soldering method, I guess.

As for the connector, seems like bad design to me.
[Galaxy S II General] victor79:
Easy solution

Smae thing happened to me. There is a piece like a fuse between antenna plugs as seen in the picture. If this piece is missing, you can't get signal. So just apply a small solder at that part and it is done. Any cell phone technician can do that, no need to send to Samsung service and pay more, if your device is not under guarantee of course.
[Galaxy S II General] Entropy512:
Not really bad design, other than maybe marking it clearly as "Factory test only" - which is why that antenna connector is there.

It is extremely rare for phones to have antenna connectors these days.
[Galaxy S II General] Lucasorgpl:
Guys, I've found a shop in Australia where a patch lead for SGS2 is available with the FME connector:

http://www.telcoantennas.com.au/site/patch-lead-samsung-galaxy-s-ii

Has anyone tried it? That question goes maily to people of Australia, because the shop doesn't ship products outside Australia.

If this cable works, we'll have the best solution for now :)
[Galaxy S II General] Aerobotix:
MS147, wheres the documentation, specs etc for this ?
[Galaxy S II General] dpuk:
Yep works great, the port is activated by the connection of the patch lead which will override the internal antenna. Make sure you buy the lead for the galaxy S II and not galaxy S, as the pin on the connector is slightly different in length.

maybe email them see if they can post outside Australia, as it's usually only a couple dollars more expensive.
[Galaxy S II General] spookyx:
Yep... I did it.

Long before this thread i have researched about this connector and what it is more exactly... I assumed it might have been for gps as well... Anyway, last night i tried a connector, which was close, but wouldn't fit... But I guess that has broken my internal antenna...

Wondering what should I do...

Why would the internal antenna break? Btw what connector did you try?

Can you elaborate more on this? a better/close-up picture if possible?

Flashing your galaxy, press Y to continue..
[Galaxy S II General] spookyx:
Probably because the central pin of the plug was too long and made a short inside the connector and the fuse, suggested earlier to be the problem, burned.

W1 ?

W2 ?

R1 ?

What about Galaxy Nexus i9250.

Hi.

Has anyone had luck fitting an antenna on a Galaxy Nexus i9250.

I have a MS147 connector and it doesn't fit.

I am not bothered about the internal antenna not working as I would only use it with external antenna.

Any suggestions?

Thanks in advance!

Regards

Nick
[Galaxy S II General] sloanyboy:
thanks mate its always best to know what its for rather than finding out when its too late
[Galaxy S II General] E:V:A:
Picture Please!

Could someone please provide a very close up picture, to confirm this?

Are you sure it's a hardware problem? (Perhaps the phone just went into Ext Antenna mode and then refuses to come back... And with that many HW problems with the SGS2... )

Removing the broken external antenna connector and only using the internal

Hey guys.

This is my first post on XDA.

I was so "lucky" to but a cheap used S2, with the promise that it worked 100%.

Unfortunately this wasn’t the case. When I got home I quickly realized that the signal was extremely poor, with the same sim card and carrier as a have used on my old HD2. Instead of finding the ***** that sold me the phone and hitting here with a pipe, I started updating the phone and searching the web for answers.

I found you guys in here and started investigating if I was falling victim to the same external antenna connector error.

Fortunately I am an electronic engineer, and have access to the right equipment for the job.

I first notates that the external connector look like it had been damaged. Maybe someone had used a wrong connector :-(. See first photo.

I found the data sheet for a similar connector (MS-147) and it did have a internal switch that disconnects the onboard antenna when a external is connected.

Data sheet, page 4:

I am not allowed to post a link to the datasheet but do a google search for “hirose MS-147 pdf”

I verified that the internal switch where broken by some simple connectivity measurement and I also tried make a small antenna with some thin wire place in the connector. The small wire gave me a couple of bars in signal strength.

So I went for it and soldered the connector out and replaced it by a small wire that connects the transmitter/receiver to the internal antenna.

Hope this helps shed some light on the issue and one way to fix it.

I would only recommend this solution if you have a thin soldering iron and some experience using it. I used a microscope as well, but this is a luxury I used because I could:-).

I think that this connector can be use as an external antenna connector, but only with extreme care and most definitely only with cable using a 100% matching male connector.

I so in another forum someone recommend a inductive cradle that can be hook up to a external antenna with a big improvement.

Again I can not poste direct link since I am a noob…..

But do a google search for this part no: CK589-AMGC
[Galaxy S II General] Azurren:
Impressive work :D

And to think.. I couldn't even fix/bridge a fuse in a NDS lite
[Galaxy S II General] kurtis.pullin:

[Galaxy S II General] leijonasisu:
I have just had the misfortune of completely breaking my device as well...

One of my neighbours moved out and gave a lot of his stuff to me. One of those things was an external yagi phone antenna..

Without even thinking I used the patch cable that was connected to the line after setting it up, just to realise that the plug for the antenna was slightly too big for the small little port on my SGS2. But it was too late, I had already broken the connector, or done whatever it is to make it not work anymore.

The thing is... I am living in

Australia

for another month. My phone is bought from

Finland

.

I still have the phone under warranty

but I have flashed the phone countless times. Though I have reset the flash counter with a USB jig, and I also have triangle away.

My question is:

Would it be better to try soldering it myself, or can I just join a little piece of wire inside it or something to make the connection come back, and never mess with it again? Or should I wait a month and suffer the fact that my $600 phone is broken and that I can no longer send or receive calls. And then go back to the place I bought it in Finland and make up some lie that the reception just stopped working one day and have it replaced under warranty?

Because I used an unofficial patch lead

there is absolutely no visible physical damage to the little antenna port

. You would have to do what 'Dr.Hammer' did at the end of page 3 (actually rip the little black button thing off) to see that I could have plugged anything in there.

Would I get away with this under warranty, if I flashed my phone back to a stock firmware, reset the flash counter and then sent the phone in for repair?

Or can Samsung somehow figure out that I have already voided my warranty TWICE.

1. By flashing even if I have reset the counter.

2. By trying to use the auxiliary antenna port (I don't know if this is against the warranty but I am assuming it is).

Anyone with any experience in this please provide some information!!... my phone is pretty much a brick now and I am not made of money so I can't just buy another one.

I can't believe this has happened, I was so grateful my neighbour had left me the antenna and that I might be able to get some reception out in the bush...
[Galaxy S II General] spookyx:
@leijonasisu

I recommend to reset the binary counter and put an official firmware and go with it to Samsung.

It happened to me too and they have fixed my phone under warranty within an hour (I'm in Romania). I just told them that the phone is loosing the signal badly. They didn't asked any other questions.

If you want to be able to use it till you get back to Finland, put a small wire into that socket and flip it against the battery so you can put the case on to of it. Try to have the wire a little bit longer, like 70mm long... You can google for a website where it tells you the exact length needed by the antenna in GsM/900MHZ and you can set your phone to only use 2G. I used a leg from a resistance or you can get something else instead... Some hard wire. Let me know if you need more info.
[Galaxy S II General] leijonasisu:
You are a legend mate. Thanks so much for the info. :)

I'll return the phone with a false sob story about how the signal stopped working one day or whatever.

I don't actually have anyone to call me while I am in Australia. LOL so it was so stupid I did this in the first place. But I didn't realise it would ruin my phone.

I'll just stick with it not working for a month... Not a big deal. Thankgod I can just use voip and Viber to call my wife.

If I can give any advice at all. I would just totally advise against even LOOKING at that external antenna jack.

What about commercial cables?

Has anyone had the problem when using a commercially available connector cable?

-TM
[Galaxy S II General] Dr.Hammer:
I have read about some using commercially available connector cables, but if there where with the 100% correct connector, i dont know.

But Samsung do not make one for this phone, that should be kind of a hint :-).
[Galaxy S II General] kurtis1:
i too often find myself in a remote area where signal is very difficult to find. if someone could make a kit that doesnt disable your existing antenna it would be great!
[Galaxy S II General] cescof:
Hy i try to write here to explain my problem.

I've replaced my usb flex port cause was oxidated and after that i don't have anymore 3g signal just gsm. My umts provider h3g is missing.....

I've also no more sound from my loudspeaker...

Please what kind of problem could be???

Wired cable for umts or in general loudspeaker part with antenna?

Any suggests?

[Galaxy S II General] TigerWild:
Thanks!

I really appreciate the heads up! I was just trying some of my own mods, I bought a nifty bluetooth / Wifi antenna for my laptop and thought I would try it with the cell phone. It gets much better connectivity for my laptop, maybe with will help reduce power consumption in cell right? LOL, the little square antenna is a great fit, but the antenna connection is special, how do I make it fit? I was goind to force it, solder it, etc. Aftering seeing your post, I will keep looking until I spot the correct connector, then solder THAT onto the tip of my antenna!

I will post back if I spot the antenna connector, thanks again!
[Galaxy S II General] leijonasisu:
Hey man seriously leave that port alone. It's not covered by warranty at all. If you touch it and there are a lot of threads about how easy it is to break then you're on your own taking your phone apart and soldering it. Even the right connector will break it. It was just put there for testing.
[Galaxy S II General] SSThing:
I ordered one of these:-

http://telcoantennas.com.au/site/patch-lead-samsung-galaxy-s-ii

I have been having problems with Three ever since they activated some Orange masts near me that have reeeeeally low data capacity, and my downloads went to around 250kb/s on average. Now I am achieving an average of around 5mb/s with this http://speedtest.net/result/2178847170.png my best lately. I have a Yagi pointing at the mast around 4-5 miles away behind trees.

So I am happy to confirm that this patch lead works!

SST
[Galaxy S II General] stiffmanoz:
yea, so I just did this to my phone. DAMN now no reception :( and my backup phone is crappy.

Currently debating weather to go through the painful way of convincing my phone provider that its broken and should be repaired/replaced, or destroying any threads of warranty I have left and cracking out the soldering iron and doing like Dr Hammer.

I've got an uber tiny soldering iron, the tip is like wire. I think that should be perfect.

The more I'm thinking about it, the more I'm leaning towards DIY. it looks fiddly, but doable.

If I do go the DIY route, I'll be sure to document it for the sake of the internet. I don't think i'll be able to get the super macro shots like Dr Hammer though.
[Galaxy S II General] republicano:
this should be pinned, i saw that connection and wondered if i could improve the signal since i can attach an antenna but can damage if its not the proper one or enable external, its used in rural areas to increase signal with antenna attached to car,etc, used for testing not made for several re insertion, the s3 has one also but they cover it

heres a video about it also posted by SSThing, the guy has a hole in the back plate to connect without removing it

Has anyone else tried the above post from Telco antennas?
[Galaxy S II General] kingqueen:
I have just ordered one, but I live in the UK, pretty much as far away from Australia as possible, so it will be a while before it gets to me.

I am less concerned about using this little port as my S2 is now old, out of warranty and will be upgraded shortly and also due to the very helpful photo instructions on how to get the phone working again if the socket breaks.

I'll let you know how I get on.
[Galaxy S II General] SSThing:
Mine took a week, if that, to arrive.

Still going strong:)
[Galaxy S II General] beezie42:
So has this new antenna only been tested and confirmed on the SII? I have a Epic 4g and would love to try this out but not if it borks the internal antenna.
[Galaxy S II General] FirebirdStud:
It is unfortunate that others have buggered their phones by exploring that port, but I have always wanted to know that that thing did. I'll stay away from it. :good:
[Galaxy S II General] kingqueen:
My cable arrived today, it took 3 weeks from Australia, which isn't bad at all given the shipping cost was minimal.

It works! Unlike my first borked attempt, I can connect and disconnect the cable and the internal antenna reconnects itself.

It came with a warning to be careful with the port and to not keep plugging / unplugging the cable. It didn't come with a back plate, so I carefully drilled a hole in the existing plate.

I don't know how long this socket will last, and I wouldn't do it on a brand new phone, but it definitely works and doesn't break the internal antenna connection when removed.
