Hey,
So I have some problems with service range, after I checked my SIM with other cellphones and checked my cellphone with other Sim-Cards I found that I have some problem with my antenna, the question is what should I replace?
the Antenna or the antenna connector cable?
What leads you to that conclusion? Merely checking your sim card in other phones and other sim cards in your phone has no/little connection with your antenna or antenna cable! There are easily a dozen or more hardware problems that could cause service range problems, not to speak of software problems! One of the first things I would check is what modem you have. Different modems act differently depending on your location. As a last resort, instead of mucking with your hardware, contact T-mobile customer service. You may be able to send it in for repair/replacement.
Hey, I bought the cellphone in the states but I'm using it in Europe so I cannot send it to T-mobile...
Anyway - I tried to switch modem version, back to stock, change roms but all are the same "****y" range..
I'm pretty sure that this is an hardware problem (while I'm holding the phone in the bottom the range is gettin really low...) the question is what I should replace
any suggests?
Hey all, I apologize in advance if this is posted somewhere already, I did search for a couple hours and haven't found anything that come close to my situation.
I bought 2 Samsung Galaxy Notes (i717) a couple months ago. With the news of running them on our T-mobile network, I was sold. Both devices were brand new, in the box and cealed from the factory. I unlocked both through the same Cellunlocker.net site for $25.00 each. I rooted both phones and installed CWM. After insalling Saurom RC7 and the Vkl1 Tmo Radio, everything was fine for about a month. All of a sudden, on my phone, I start losing Network/Data, needing a restart to get it back. Over the past month, I am up to an average of 20-30 restarts a day and sometimes it only works 50% of the time, the other 50% I get nothing, at all.
My 2nd phone (wifes) has no issues at all. We both have the same OS/Radio's on them, nothing is different, except for the IMEI number. We both have them in the same area for use and mine will crap out all day long. Nothing I do fixes it. I have replaced the SIM 4 times, reinstalled the same or a new OS many times, Ive heard, oh its your radio, need to reflash it, corrupt file, the list goes on. If its something that you can suggest, I have probably already tried it, software wise. . T-mobile cc says its cause its unlocked, well my wifes is unlocked and doesnt have an issue....soooo.
The only thing I can come up with is there is a difference in Hardware, between our phones. Not intentional, but maybe my Network/Data, antenna is lose or broken and hers isn't. Thats the only thing I can come up with, other than the unlock code is bad, but if thats it, then why did it work solid for a month?
I am at my wits end, I went back to my sad pos Vibrant, that works. I took my note to a local repair place to run diag tomorrow. Hopefully its something they can find and fix and not bend me over in the process. If anyone has any info on this issue, or has had the same problem, please feel free to fill me in.
Thx all in advance

Based on the fact that you are running two identical devices ,with identical software etc.
And based on the timeline of trouble that yours is having ...I'm leaning toward a material defect in the device.
The evidence is simply too strong to ignore ...IMHO
A warranty return is my suggestion ....
And I'm very sorry to hear that news ....g
Just an update....I picked it up from the cell repair store. They told me, my antenna needed to be reseated. Once done, I havent lost signal yet in over 6 hours. Good news is, they didnt even charge me.
If it happens again, I will keep this thread updated, otherwise it looks like it was a hardware problem after all.
Yep...
As expected ....
And great news on the free repair ...g
How did they reset the antenna was it software or did they open IP the device
Sent from my SGH-T879 using xda premium
open the device and push the antenna connecter into its seat.
Easy to say, difficult to do. I don't have a link, but if you go to youtube and search "galaxy note disassembly" you can see it and decide if its something you can do.

Not this guy ....
My shakey old fingers, and poor eyes don't wanna play.
So you might get a pm one day ranger ....with me begging for help on the other end ...LOL ....g
Ok so....my paper weight, still doesn't work. I guess I spoke too soon when I replied all was well. Im not sure what the cell repair store did other than reseating my antenna, but it worked great for a solid day, then started acting up again.
Today I switched my wifes SIM for mine, to try and determin if I just had gotten really unlucky with bad SIM cards. Nope. My SIM worked great in her phone, got signal right away. Her SIM in mine? Didn't get squat on mine, meaning its most deff my hardware (SGH i717).
Long story short, don't purchase online....so you have the ability to take it back to the dealer and throw it through his/her window. I love the Gnote...hands down, coolest phone I have ever had....just wish I didn't get a dud. After all this time, I still haven't heard of anyone having the same issues. I can't be the only 1.
Edit: Just spoke to Samsung and they said it's an issue that happens with the Reciever/Antenna and needs to be repaired. They looked up my IMEI number and said its still under warranty, even though, I took it to a cell repair store and its unlocked with mulitple flashes. As long as it has no water/physical damage, its covered. So I guess I will find out in a couple weeks.
Bad news /good news I guess ...
I'm glad it's getting fixed .....by samsung.
And no ....
You are not the only one ...
There have been 4 others I know of ....
But at this point it's looking like a software issue, with your device being the exception having a hardware failure....g
Same boat
Hi, I purchased a Rogers i717r used. It came with a custom ICS ROM installed based on AT&TI717UCLE2. It seems to have a similar issue most likely hardware related. Although it would show some signal level it didn't regularly connect to the network. It wouldn't let me make calls or use data. I wanted to make sure all the band were turned on so I followed the guide I've used for other Galaxy devices (see below). It was set correctly to automatic. To further troubleshoot the issue I tried turning on only the GSM frequencies 850/1900 (which is what Rogers uses). I connected immediately to the 2G network and got excellent signal strength. I could make calls and use 2G data. Trying to use only the 3G CDMA bands did not work nor did the COMBI BANDS.
I believe this phone has a antenna wire running from the USB charging/dock board to the mainboard. I wonder if this wire or connector has been compromised. I think the previous owner said the USB connector went bad and it was replaced at some point. I may have to open the phone at check the connectors.
Before I start investigating the hardware, I will try to get it back to stock.
There must at least 3 antennas in this phone maybe more. WiFi, GPS, GSM, 3G, 4G, (possibly multiple for different bands). I'd like to know which one is which.
Any ideas on how to troubleshoot this is appreciated.
Open the Phone Screen and Type the following code:
* # * # 1 9 7 3 2 8 6 4 0 # * # *
The phone will automatically take you to a screen called:
SERVICE MODE
AND YOU WILL SEE THESE OPTIONS:
----------------------
[1] DEBUG SCREEN
[2] VERSION INFO
[3] UMTS RF NV
[4] GSM RF NV
[5] AUDIO
[6] COMMON
----------------------
all these options are written very very small so you will have to touch the screen very accurately to get the right one... so select them in the following order:
[1] Debug Screen
+
[8] Phone Control
+
[7] Network Control
+
[2] Band Selection
Once you Tap on "Band Selection" you will have a screen stating these 4 Options:
-------------------------
= BAND SELECTION =
[1] Automatic [*]
[2] WCDMA Band []
[3] GSM Band []
[4] Combi Bands []
-------------------------

Someone was nice enough to make a Nandroid backup of the stock ROM. It didn't solve the issue though. It still isn't completely stock as the superuser app is still install along with recovery. I guess I need a copy of the unrooted kernel just to be sure it's not software. While in stock GB 2.3.6 I tried the software update feature to upgrade to stock ICS. It reported there was no update available. My guess is it can tell it's been rooted.

I have called and talked to atleast 10 people today, trying to find out what the problem was. What component was replaced, what exactly was the issue. I can't complain, I wasn't charged and the communication thus far, has been top notch.
Does anyone know what PCS Service is?

See wikipedia:
At the most basic level*Personal Communications Service*or*PCS*describes a set of*wireless*communications capabilities that allows some combination of terminal mobility,*personal mobility, and service profile management.[1]*More specifically, PCS refers to any of several types of wireless voice and/or wireless data communications systems, typically incorporating digital technology, providing services similar to advanced*cellular*mobile or*paging*services. In addition, PCS can also be used to provide other wireless communications services, including services that allow people to place and receive communications while away from their home or office, as well as wireless communications to homes, office buildings and other*fixedlocations.[2]*Described in more commercial terms, PCS is a generation of wireless-phone technology that combines a range of features and services surpassing those available in analog- and digital-cellular phone systems, providing a user with an all-in-one wireless phone, paging, messaging, and data service.
I figured that's what that meant. I would still like to know what component was replaced. Part# or Sku would be nice, but they are very vague lol. Should have it by Thur/Fri so I will update then if it's still not working and what the overall outcome is, also info on what "component" was replaced, with any luck.
I had the exact same problem after unlocking my i717 through your same online unlock code shop. Signal would drop all the time. I flashed every radio version I could find and that didn't help. Only other thing I could do was flash different roms and see if it somehow fixes.
Haven't used it for a while, but was just re-flashing it so I could gift the device to family and found the Padawan JB v2 and the stock deoxide roms from jedi roms brought back the signal lost. I flashed the latest AoCP 5.8 (http://forum.xda-developers.com/showthread.php?t=1773229) and no signal lost in the last 12 hours. I'm also on radio version I717UCLF6. Hope this helps anyone else that stumbles on to this tread.
OP, did you figure out which part had to be replaced? I'm having the same problem. I wish Samsung would release this information, such a headache

Has any one figuired out which part of this phone needs to be replaced to fix loss of signal.
Hellu!
A friend of mine dropped her SGS2 accidentally into the bathtub but was quick to retrieve it. After drying it she got it to run but there was no response from the USB port so she couldn't recharge it. I replaced the USB flex and while having it hooked to the computer I upgraded it to the latest firmware through KIES, all official and no trouble. Gave it back and now she can't get signal... Problem is that I don't know if the signal trouble was before I replaced the USB port incase I "broke" something while fixing it.
No signal, no mobile network. I get no signal and can't make any connections to any provider.
Things I've been trying and reading up on..
IMEI is correct, the EFS folder intact ("mount" in Terminal emulator) and backed up also.
Opened up the phone again to check if internal antenna was attached to the sockets and everything else secured.
Tried different SIM cards which it accepts except for no signal
Factory reset
Flashed a lower ICS (4.0.3), changed CSC, tried different basebands
Rooted the phone and did a complete reset from CWM (dalvik, format system, cache the wholeshobang)
Internet wifi works, the signal strenght is stuck on "-111 dBm 1 asu"
The whole time after the water accident she's been having the phone with her without the backcase, leaving it open. I read that if you connect a external antenna it will override the internal one and get stuck.. I though maybe keys or something metal in her purse got in contact with it?! (I know, far stretched)
Perhaps the USB flex replacement is bad since one end of the internal antenna is attached to it. I could try to replace it back to the bad usb flex.
OR... Perhaps it's just another failure due to the water accident...
Phone seems to be in great shape except for missing it's main purpose, being able to call
Help

Nope, tried it and no go, seems more like there is a hardware failure after all, any more ideas?
Tried another USB flex to see if that was the problem but no.. . Anyone?
Ok.. Replaced the GSM/speaker part located at the backpart now and still no signal. Well.. When i reboot the phone I get a connection and may be able to make a short phonecall then it's just back to no signal.
Been reading up alot and I found out there is some kinda "no service bug" that exists, but all the solutions there didn't work so good.
I have same problem on a i9300 gonna see if it's antenna problem or something. And post back of I got lucky
Seems like the phone needs to get some service center time.....
BTW never connect anything to the external antenna socket.
Sent from my digital submersible hovercraft.
I have a similar problem with a i9300. Is there a way to check if modem or antenna is not working? I remember about read a few days ago than android throw some errores when modem is not working
Hello to all
Yesterday I go to shop near my home the fix androids and iPhones and the tech tell me maybe is good idea replace the board (IMEI us different from the back and can't get signal in simple mobile same as Tmo well my question is how I really know if the board is damage?
Thanks in advance for any help!

Well have you tried different modems as well as the correct APN settings for those carriers?
I do not know how this "repair shop" gets their hand on the logic board to begin with.
I had been looking for a logic board, but NO ONE has it. Not even the supplier of Samsung repair parts. It is not for sale.
So, it sounds like they may be trying to trick you and charge you a big bill to "fix" it, when the solution is most likely as simple as flashing a different modem.

Yes Sir but let me try it again so if the APN is incorrect this matter on signal and calls? i mean with my skyrocket i never put the APN phone automatically loads (Tmo apn not simple mobile) and works better than the simple mobile itself

Afternoon, XDA people.
I recently repaired my brother's S II after he broke the USB port by dropping it while plugged in. I ordered a new flex and antenna (because I broke the old antenna) and after installing all the new stuff, it gets awful to no signal. He's on Straight Talk (ATT) and usually gets 3-4 bars where we are, but now the cell rating doesn't go above 111 dBm, 1 asu. I've tested his SIM in my S II and it works fine. APNs are the same. I also updated the modem to the most recent one for ICS AOSP (he's running CM9), factory reset, all that fun stuff.
Could it be that the board has more to do with signal other than having the mic, USB, and antenna connection on it? Should I order another board and see if I had a faulty one? Should I throw it in a blender and see if it blends? Whatever insights you all might have would really help me out, because he has to have a working phone to make sure he'll have work throughout the week, and I don't want to give him a phone that isn't reliable.
Thanks for reading

You should do something like this and also nake sure that part numbers you installed match to one you replace. ...look one more time to connection
Also run service mode something like this
Success is never final
Failure is fatal
Fixed it

Wow, I totally forgot I posted this. Thanks for the response, samprocat. Turns out that the board I got was for the international edition, not the i777. Got a board for the i777 and it worked on boot, no issues. Tested for 4 months and going strong.
