Weak signal after changing USB port. - Galaxy Note II Q&A, Help & Troubleshooting

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

Well in this case as mentined above that the usb has nthing to do wth the signal but the wire that is connected to the usb has so try to get org samsung note2 usb port as I even found that few usb slot that I being sold in ebay are not exact the same as original so try to get an authentic usb port as definately the wire which is attached to your new usb port is hvng prob catching signal so it seems that the port is nt wrking fine try to get one from a geniune seller from ebay whose feedback is positive related to the usb he is selling and 1 more thing do u have an international version I.e. n7100 or n7105 or other specific carrier be sure on what you are being rather bfr purchasing confirm with the seller the exact model code written on the usb port.

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...

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.

LMFAO>> people buggin on you with the wrong correction
there not antenna connectors.
there diagnostic ports.
(Now i could be wrong and instead of being U.fl Diag ports they could be W.fl
just size difference really
where going on the base they are u.fl but the same applies if W.fl
if you notice there UFL but there not the same as the U.fl on a wifi card..
and they arent just a connector.. ,d
so going back to they being diag ports. they dont act the same electricly as a "antenna connector" remmeber there diag ports not external antenna connectors.
they also have a disconnect in them so when they are being used the "stock" antenna is disconnected
this is so the diag whtver gets the full power from the Transmiter and its gets the full signal from the diag machine. (IE to test TX and RX power and other stuff)
they have about 20 connect/disconects before they go to crap.. (They are NOT FOR ANTENNAS ON A PHONE> THEY WILL HURT YOUR RADIO>> PROMISE> THIS .
you cant buy the proper diag port connectors easily either
there are a few types most are ment to be held in place and dont really snap on. then there is one that looks like a ufl with rp with a small Coax.
so that one would be the one to start with but then you are into resistance etc. and the diag machines compensate for that a standard antenna wont.
a u.fl diag port disconnects the stock antenna.. and is used to be either or..
where the U.fl or w.fl is a Connector desinged to send all power to one place (antenna)
now if you know what you are doing you can use them as an antenna connector if you take other things into consideration and match it to work. THiS IS NOT FOR THE GENERAL XDA FORUM USER> NOT EVEN MOST MODS> as they are software peeps and not hardware (dont flame)
OMG>> all these hackers here and no one has posted the correct info.
here are the pdfs for u.fl and w.fl they dont have the diag port or its assoisciated connectors (thingys more like it)

now i have the pdf for the diag but i dont want to upload it as i got it in email from H japan.

Phone is ruined?

So, I think I am screwed.
I am going to preface this by saying that I am very familiar with Android phones and am certainly not a noob. However, i am stumped here.
A few hours ago I tried updating my girlfriends phone to the latest version of MIUI 4. Well, it turns out that I was the poor guinea pig who found out for everyone that the uploaded file did indeed have an MD5 mismatch.
Anyhow, this borked my recovery (supposedly because a new kernel/cwm version was baked in to this flash).
Ok, I thought, I'll just put the phone in "Download Mode" and Odin back to stock and start over.
WRONG
The phone is NOT RECOGNIZED ON ANY COMPUTER. Not two different laptops running Windows 7 64-bit. Not a desktop running Windows 7 32-bit and not a Linux Box.
This isn't the typical "unrecognized device" error. I literally mean that it is NOT SEEN by any of these machines. There is no Windows "ding" or "noise" when it is plugged in. Nothing shows up in device manager as an unrecognized device. Nothing happens when I plug it in to my Linux machine.
I have tried FOUR different cable. The original Epic cable. My Epic Touch cable (which used to work great). A cable from a Nook Simple Touch and a cable from an HTC phone.
I am 99% certain that this is a hardware error and her phone is now ruined. She does not have TEP (she cancelled it for some reason -_-).
Has anyone ever heard of this? It can't be a driver issue because it would at least be seen by one of my devices correct? Or there would at least be a Windows "sound" when it is plugged in? The phone charges when connected, but nothing more whatsoever. I had issues in the past because of driver issues or bad cables. But, the fact of the matter is that the other day (when the phone was working fine) we plugged it into a computer and it would not recognize the phone at all (as I explained earlier). Even when storage was mounted, not a single thing was detected even though it used to work.
Sorry for the long winded and redundant post... It's quite late and i've been trying to fix this without freaking the woman out for the past 3+ hours. Driving me insane!
Anyone have any ideas? Or, any options I can take for if it truly is a lost cause?
Thanks everyone
uninstall all other phone drivers. Reboot. Install the drivers here : http://forum.xda-developers.com/showthread.php?t=728929
Windows is very very picky with drivers. If that doesn't work none of the cables you have used is a blackberry. I would say go out and buy a good blackberry cable or at least a good thick cable. Try another USB port as well. You can even try a fresh install of windows. If all fails then the USB is borked. Or it is dirty... see if you can't clean it out if you can see any lint or other gunk.

This might seem really crazy but i had the exact same problem about a year ago. It wasn't the cable, computer or the drives.
check the little connector piece in the phone where cable meets the phone. Its a small copper piece that can be notorious for bending up or down. I could charge my phone like you but couldn't figure out why the hell it wasnt syncing so try that and i could guess that's the issue. since its your gf's then Im sure she has some tweezers that an bend it back up but be very careful.

Also, the connector is physically bent. I'm going to try and bend it again today. The sides visibly form an ever so slight "u" shape.
I took the phone apart as well last night to get a better look. That piece does not appear to be interchangeable whatsoever. The entire input is like, awkwardly soldered to the system board...

you could get it JTAG'd. I'd Google for jtag services which will unbrick a hard brick. I doubt sprint will replace it unless you have a cool rep.

Do you think a JTAG would work? I truly think that this is a problem with the actual USB connector (we had problems with it before it got "stuck", EX: It wouldn't mount USB storage on any machines... Not detected at all when plugged in, aside from being charged). It isn't actually bricked... If my recovery would not have been wiped out by flashing the ROM with a bad MD5 OR, if I could get it to work on a PC/Linux machine I could easily Odin/Heimdall. I'm not exactly sure what a JTAG is, but I am 99% sure that I could fix this if it weren't for some crazy ass hardware issue. I'll try calling around.
Thanks man.
Its a direct communication with the board, is what I've grasped from hearing and reading about it. With this and a program it should rewrite things and allow you to flash things. Although now that I think about it your not hard bricked if you can get into Odin. And jtag usually puts it into download mode. Although I'm sure you can flash the stock firmware via jtag. Like I said Google things

Although now that I think about it your not hard bricked if you can get into Odin. And jtag usually puts it into download mode. Although I'm sure you can flash the stock firmware via jtag. Like I said Google things

[Q] Simcard Required to Connect to PC?

Anyone know if a simcard is necessary to connect the S2 to a computer? I haven't been able to connect to the pc, and yes I've installed the drivers. I'm waiting for a replacement screen that I'm going to install, but wanted to play with the phone before I take the simcard from my fiancee's old phone. I don't think she'd appreciate having to use a phone with a cracked screen for another week just so I can play with it =)
Edit: Whoops, should've posted this in the Q&A forum. If a dev could move it for me, that'd be wonderful. I'm not used to having a separate Q&A forum. With my Revo we only have a general section =(.

The answer is no. Lol. Sim card is only needed due radio operations.

Yeah, I didn't think so. I was reading something that suggested that the sim card is the problem, but it seemed a little bit weird to me. The other two fixes i can think of are that i actually need to buy an official samsung charger (although I'm not sure why an lg charger would charge the phone but not allow me to connect to my pc), or the USB port is bad. The Guy i bought it from mentioned that it would only charge if you held it in the right spot, but i haven't had that problem. luckily the USB port isonly 7 bucks with expedited shipping

Well if the port is bad, I'm going to place my money on that being the reason why it's not connecting.

nexus not charging

i know it is already posted but my issue is different. Some can charge their phone when it is off but mine cant charge even if its off.
When its off and i plug the charger the lightning logo appears, it indicates that its charging but when i turn it on the percentage of the battery remained the same. it didnt charge at all. Also my pc does not recognize my phone whether if its off or on.
i tried with no luck changing rom, kernel, used different cables and chargers (i even used one from LG).
i want to take it back to samsung but my bootloader is unlocked, im using costume rom, and rooted. They will not accept or repair it
EDIT: i want to install the stock rom and relock bootloader but how? since my pc doesnt connect to my phone
Look in the development section and download the nexus toolkit.

Use a cocktail stick and try push the chipinside your phone slot upwards a little (if the phone were laid faceup on a table). Be delicate as you dont want to force it, but a little nudge up and your problems should aaaaall be resolved.
ive already done that no luck.
bump!
if i can restore my phone to stock recovery, stock rom, stock kernel, remove root will they accept it(warranty)? or do they have something to know that i modified my phone?
EDIT: because im planning to return in back to samsung
Please read forum rules before posting

Is it a play store model or international? If it is international and you are located in the USA, Samsung will not do it. You can replace the usb port yourself..
mine too
Mine did the exact same thing. Good luck sending it in and having them actually fix it. I'm beginning to think their tech guys are really just a room full of chimps randomly putting stuff together.
I told them exactly what the problem was (because I looked it up before sending it in and my problem was the exact same as everyone else's) and they ignored me and just switched out the battery. That didn't work, so I sent it back again. Then, they updated the software. Since it's a hardware issue, obviously that did nothing. Now, they have repaired the PBA. I don't know what a PBA is or what it has to do with my USB port, but I'm betting the issue still will not be fixed and I'll have to send it back, yet again. After all this mess, I think I'm done with Samsung entirely.

i have sent it already. fortunately i was able to return to stock without USB. Hope they cant detect that ive done a mess on my phone.
probably the repair shop where you took your phone are just too lazy to repair. I hope they wont do the mess they did to you but i think it depends on tech guys if they are lazy enough to repair.

Did you get it fixed?
This is kind of what my phone is doing too (here's the thread i've made)
http://forum.xda-developers.com/showthread.php?t=2059289
It will charge, but only to a certain point, regardless of rom, kernel, on or off, etc
over the past few days the maximum charge has gone down and down. Now it only charges to a max of 82%. I have 2 batteries and it does the same thing on each. My (hopeful) solution is that i bought an external wall battery charger and will charge batteries that way. I have the verizon model so if i wanted to do some sort of warranty work i'd probably have to go through them (not even sure if im still covered). I really dont want to deal with it. It boggles my mind why my phone is doing this though, charges fine but not to full. Oh well c'est la vie.

i wouldnt recommend that to people, for me it went from a phone with "phantom charging" (ie flashing on and off for charging) and issues charging to a short circuit on the usb connection, so that the phone switches off when a usb cable is plugged in. What is well worth trying first is simply giving the port a good clean, a little bit of alcohol and that same cocktail stick may well solve your issue. I've been left charging via a chopped up usb cable to the dock connectors.
i dont doubt that forcing the tab in the port may have worked for you, but it has failed badly for others (ie me), so just be careful suggesting it
I had a similar problem as my micro usb socket was damaged. Don't worry about sending it for repair, do it yourself. The circuit board with a new micro usb socket is available on ebay, I paid £5 for mine. Watch a tear-down video or 2 on youtube and you will be sorted.
The GNex is easy to take apart requiring just a small philips head screwdriver and a pry tool, i used a guitar pik, and these are also available on ebay for just a few ££'s.
Can do the whole job in 15 minutes.

[Q] Service Bars

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
