Hello,
Here on the picture, I surrounded in RED, a part of the SGS2.
Can someone tell me what is it ? (This part is missing on my Samsung).
My problem is that my SGS2 doesn't have the network since he felt, but the wifi and everything is ok...
I need to replace the network, can someone tell me where to find this part?
Thanks
Nobody can help ?
Thats the connector for an external antenna....most likely your network board is screwed...

If you have warranty take it back to samsung

did you by any chance reset your phone with the phone plugged into a charger - sometimes when i do this, i lose network connection. Try resetting your phone on battery power.
You may have also screwed your IMEA. Search the forums for solutions for this.
My charging port is fried after attempting to make an at home Y cable to charge and have USB OTG. I see the ports on ebay for just a few dollars, and would love to switch it out, but I dont want to break anything.

So, how the hell does that thing connect to the motherboard? Is soldering involved at all?

i strongly suspect some soldering is involved. there is a video thread here about about taken the epic apart i know it says for screen but it should get you in the right direction.

Yea, that was my fear. I took the epic apart about half an hour ago and was staring at it trying to see how it might be removed, but didn't want to completely ruin it by guessing. Been searching far and wide to see if anyone has done it on their phone with little success.
sounds like the seller would do it for you for an additional $30 dollars? Just gotta ask yourself, Is it worth it or are you willing to take that chance?
Maybe you can just ask the seller for directions on how to replace it, I'm sure he'd be helpful.

There is an elite developer named adam who can definately help u with this, just search for any of his threads and ask him. He is the one who created the unbrickable mod

JTAG dump??
I'm not sure what you are asking but JTAG is not a kind of "firmware" or "software" on your phone.
You may find a JTAG being visible either under the battery or near the SIM/SDCard holder, its a circuitary pin-layout hidden, one may have to dismantle the back cover, usually 6 gold pins in a cluster close together.
It is that, using a special hardware box that has a vast-array of cables with designated pins (depending on hardware manufacturer), along with specialized software which would be specifically made for that particular handset.
The micro-code instructions are emitted by the hardware box attached to the cable, clipped in position on top of the JTAG pin-outs, which sends a signal to some part of the chip to revive it, and then from there, a appropriate firmware can get flashed into place using this method.

What? I really do not think you know what you are looking for.
My phone started acting up about 2 weeks ago. It would not charge all the time and my PC had a hard time staying connected to it. I ordered a new USB port from eBay and installed it. I am getting a weaker than normal signal, but what is really weird is that when I remove the sim card, I still have 1 bar and sometimes 2 bars of signal. I have tried rebooting and pulling the battery. Is there a way to reset my signal meter or something? Maybe I could reflash my ROM? I don't know, does anyone have any suggestions?
Oh and this is the second USB port that I have received from an eBay seller. I sent the first one back for this reason but the new one is acting the same way.

Chk settings/more settings/mobile network/network mode -gsm only see if there is any diffrence now
Be sure while fixing the usb that the network wire attached to it fine as that may be the culprit

Thanks for the suggestions but nothing helped. I'm in my house now where I should get hspa+ and I only get edge. I guess I might have to try another source for the USB port.

Well as u already replaced the usb again it must not be faulty as I had problem wth the usb 2 and when the servc guy changed it in frnt of me and after fixing it back I got no network as the wire connected to it which is on the right hand corner went kaput as a little force applied by the servc guy resulted in no netwrk and it was fixed replacing the signal reception wire .I hope u get which wire I m talking abt its the thin wire to right of the pcb board dat is attached to the usb port by just pressing it to the usb port on the lower right.
Yeah I know the wire your talking about. I can plug my original USB port back in and it gets a good signal but as soon as I plug the new board in the signal goes to crap again. If I can't get it to work I may just use it as a small tablet and use my nexus 4 as my main phone. Thanks for the help.
Yep, I just put my old USB port back in and got H+ right away. I re-installed the new one, and now I get no service.

A few pieces of information:
- USB has nothing, repeat _nothing_, to do with radio reception levels and adding a "USB port" (I assume that means a additional USB adaptor for your laptop) is not going to change that.
- If your cell phone does not charge properly, or not at all, the very first, and cheapest, thing to check is your USB cable (I had that happen to my daughter and her Blackberry), so try another cable. A short one preferably as I have a fairly long (1.9m or 6'3) one on my desk that is next to useless
- the second thing to check is to plug other USB devices (USB stick, camera, other phone, hard drive, camcorder, whatever...) in that suspected faulty USB port to see if they behave properly or not. If they do, then the port is most probably not at fault.
- If the phone is set to only use GSM, or you have selected manually a GSM cell to attach to, the phone will stay there and monitor the GSM network. You could have 5 bars H+ signal in the home and not know about it (at least all the phones I've used over the years behaved that way).
- You're supposed to be able to make emergency calls with a bare phone, so I would hope you still get reception when the SIM is out.
Finally, and seeing your other posts where you signal that changing "USB ports" changes the radio behaviour of your phone (which I have a very hard time believing), I have to assume there is a communication problem there...
Could you describe a little better, maybe with pictures, what it is you are really trying to achieve, please? Does the phone work fine when _not_ attached to a "USB port"? What do _you_ call a USB port and why do you need the phone to work while attached to it?
If indeed plugging the phone in some USB ports impacts its radio behaviour, then I would assume the phone is FUBAR and should be returned and replaced...
HTH,
François

We are talking about this, http://www.witrigs.com/replacement-parts-charging-port-usb-flex-cable-for-samsung-galaxy-note-2
I have a video that I recorded this morning that I I am uploading to YouTube. I will post a link as soon as it is done uploading so that you can see how the antenna plugs in to the USB port and that it does make a difference in my signal and data connection.
There was no need for all the sh*t talk in your first post. If you don't know what you are talking about then you shouldn't make posts before researching the topic.

Back off, man!
Nowhere does it say in the OP you are trying to replace the USB port INSIDE the freaking phone, and I made it abundantly clear that I wasn't sure what you were talking about and assumed laptop USB port. I even guessed I was misunderstanding you and asked for the picture to clarify.
Based on that, I tried to offer advice based on my own experiences with cellular phones both at home and the office. And to bash me like that when it's obvious I'm not a native english speaker is a bit disingenious.
Anyway, however you want to write it, the antenna doesn't plug into the USB port, as you say. Again. The part you bought may accomodate for the connection of both the motherboard and the antennas, it does not mean antenna and USB are interconnected. They are not. The only thing I'll concede is that the amplifier may derive power directly from the power lead in the connector (and why it would do that when it gets it from the battery already?)
that's it for me, feel free to ignore me in the future I won't miss it.

Were you dropped on your head when you were born? Or did you eat lead paint chips? English not being your native language has nothing to do with this. I understood you fine. Its just you don't know what your talking about. The antenna does plug directly into the USB port flex cable.

Curiosity killed the cat
Flex cable are the operative words there. But you're right in a way, I didn't know what you were talking about until I saw this picture.
Also, I do think miscommunication can clearly be attributed to country differences. You were not being very clear and I missed your point entirely. At least I thought about the possibility,you should give me that...
Peace?

Yes, that's the same picture I found. That antenna connector links to the radio on the motherboard.

Me neither, and I get fed up witnessing people getting dragged into meaningless disputes.
About your problem, now that I can visualize it...
I have a Note 2 LTE whose radio stopped working correctly last january, as well as a co-worker's S3 (lab phones). We thought it was a bad manipulation in the phone service menus originally (we had to apply the same to both for work reasons), but that has been ruled out since.
The real reason for the mess up, it seems, the only one left to us at least, is that we were working on a bench with wired radio and had to plug radio leads into the connectors (there are two on the LTE model) to get coverage. Must have broken or changed something within the phone to explain the loss of sentitivity...
Not sure that's going to help, but you may have more than just the USB port flex cable broken on that phone...
I take that back. I now have a clear view with the video and context. I'd say your issue is with your spares. You'll probably have to swap them until you find a good enough one.
good luck
Thanks for the info. I would definitely assume that it was something other than the USB port flex cable if I did not get good signal and data connection with the old USB flex. I've seen people on the galaxy s2 forums that have the same problem as me and have actually cut the original part in half and the new part in half, taped them together, and this worked! I haven't tried that yet. The thing that threw me off is the signal with no sim card. In the USA when you take your sim card out the, the signal meter goes blank, on every phone I've had at least. I know I can make an emergency call to 911 but the signal meter is always blank. This is also true on my nexus 4 when I remove the sim card. Maybe I can find a part with the same rev. # that will work for me. Thanks to everyone for your input.

Well whatever u r doing is completely fine so just chk the model of the flex usb as it seems that is the culprit to your prob as if in org is wrking fine thn u nead to deal wth he usb flex find a genuine dealer in ebay or rather take it to servc center if u hv ny n pay thm to fix the usb flex
Yesterday I replaced ad USB board (as an old one become faulty and I have had problems with charging the phone). I can confirm I used the appropriate board model.
Today I noticed that my service bars are not as good as they used to be. Generally in the room I usually used to talk and have weak 1 bar service, right now I have no service. I tested my phone outside as well and have a feeling like the phone has no as good perception as it used to have. Another words the service bars wen down everywhere about 20% or so. Phone works fine and I see no other problems. I wonder is there might be something that affects the service bars hardware-wise ? Any ideas appreciated.

The antenna. I think we have 2, one for GSM and one for LTE.
Google for a picture with exact location and try to re-tighten them.
That's all I can think of.

Thanks for suggestions. Yes the one for GPS works fine as I have no problem with GPS (that is the one on a foil. The one for connecting to the tower is a straight wire. This wire goes from the little board (with USB port I've replaced) to the MB. I reopened the phone today and removed the antenna cable. Tested for continuity - OK, cleaned the connectors but still not luck.
I wonder if this could be some compatybility issue or deffective USB board. The board shows T889 rev1.0 so it sound like it's one of the first ones. Unfortunately I made a big mistake (to late) and thrown away old board. It had a problem with the USB post but there was no problem with the signal strength. I wonder if it is common for the usb board to go bad or if there is anything else I could possibly check. I ordered new antenna cable and thinking about getting another USB board, but if this will not fix the problem I'm clueless. I also restored the phone to factory settings to make sure it is not software problem. I need to use this phone daily at work and I'm really pissed off with the problems. PLEASE HELP
Thank you - ARTHUR
Just a question, ,, have you tried flashing the modem? Not sure it would help but maybe rewriting the radio files will help you.
Good luck
