[Q] Replaced USB Flex + Antenna, now No Signal? - AT&T Samsung Galaxy S II SGH-I777

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.

Unlocked i717 contantly losing Data/Network

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

[Q] Water damage - Changed usb flex - No signal - IMEI working

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

If it locked once you start with non-original operator sim card it will ask you for unlock code, so you will know it's locked
do you receive sim error after airplane mode ?
Mine has a bended / broken sim reader pin and didn't recognize any sim card and after restart I got SIM error msg.
I have somewhat of a like issue. After restart takes a LONG time to connect and update the tile. Wife's phone, will state no service or emergency calls only, but she can text out AND I can always call her, so POSSIBLE the tile is not updating. Sim card replaced twice by ATT. ATT stated working on local towers for LTE upgrade, and after a whole weekend of no text coming in (able to text out)(???) all incoming test text messages (say 25) arrived at 6am on Sunday morning.
no data updating (email) while in this half-working mode. next thing I can think of is get new phone.

If the phone is the ATT model and is still locked to ATT then you obviously have an issue with the phone and should sen it in for service. There is no reason why an ATT phone and ATT SIM should have an issue on the ATT network otherwise.
I have this issue as well but only since I got it back from Nokia repairing the dust in the front camera problem. They changed the internals for some reason and now I have No Service and also now have new IME number. I contacted them and they said try a hard reset which didn't work then said I would have to send it back again for this to be repaired which when I got it back today has the same problem still. There is nothing wrong with my SIM card and have even received a new Orange one which still did the same. When I contacted Nokia they were next to useless saying I need to send it away a 3rd time (my phone was perfect before I sent it away apart from the dust in the front camera...don't I regret getting this fixed now!) which I declined and have asked to speak to the manager. I have to wait 3-4 business days for them to ring me and see what can be done. I know this is probably not much help but will let you know the outcome as it might be a setting or something I can do with the phone.
One thing I have found is Nokia Care is they are the most unhelpful company ever! Basically just suggesting I keep booking it online to be collected for repair. Once this is sorted I hope I never have to deal with them again!
At&T no Signal as well
Default AT&T Lumia 920 bought from ebay NO SIGNAL ! I flashed it but... no signal
--------------------------------------------------------------------------------
I bought this yellow Lumia 920 form USA. I live in Europe.
Unfortunately it was locked, I called AT&T and they gave me an unlock code and now it's unlocked.
I put 2 different SIMS inside but the phone shows no signal at all. It reads the SIM from inside ( services etc) but It will not lock to a signal.
When I boot it it shows an airplane mode and in 2 seconds the no signal icon. The airplane mode is disabled thought I checked enabling and disabling.
I decided to flash it to Rogers after reading all these comments here using Nokia Care Suite. It was succesful. The conversion was from RM-820 AT&T to ----> RM820 Rogers Canada.
I had the ability now to change from LTE to 3G and 2G but to no avail. The signal remained dead and it wouldn't find any signal after searching for new networks associated with my 2 sim cards that I tried.
If I flash it again to the rm-821 euro dev rom will it work ? The thing is that I can't find it nowhere to download it. Where did you guys found it from ?
Thanks
Lumia no signal
Try hard reset!!!
Permanent no signal sounds like it could be blacklisted by the networks, check the IMEI here and it should show if it's blacklisted http://www.amta.org.au/pages/amta/Check.the.Status.of.your.Handset

I had this issue with a replacement Lumia 920 that I ordered online. To fix this you will first need a t5 torx screwdriver in order to remove the two screws from the bottom of the device. Once those are out you have to pry the main body of the phone from the polycarbonate case and expose the bare backside (*giggle*). look to the upper right portion of the device for a really thin coaxial-esque cable... this is the antenna. To fix my issue I simply had to push the connector piece back into it's slot. There will be a firm but tiny click once this is properly inserted and you should now receive a signal on your 920 again. (apparently the build of the phone makes this piece pretty easy to become disconnected which is why we see a lot of this issue from various 920 owners). I hope this helps, if you need further instruction/pictures let me know.

Hi there if you can also send me some pics etc on how to do this. that would be great.
I got this wife for my wife and have it for close to 5 months and it won't work.
And she really loves the phone
thanks

I have this same issue, although hitting the phone on my hand or flexing the phone will cause the service to come back until its jostled again. ive tried to find a connection with the antenna but no luck,
I have the same issue too...
At first I notice that my phone became hotter in my pocket and the battery drains quicker than usual.
After that I just thought maybe it was because of the bad signal on that area.
Then I got home and facing the same thing, my 920 still got "no service".
But I notice in the full signal area, my phone still can catch the signal. And when I get into the lesser signal area, all I got is "No service"
I've handed it up to the Nokia Care. And they fix it and cost me Rp.750.000 (US$60-65).
And still I'm having the same problem :crying:
Same problem, no connection on 3g, but 2g works fine
Hi,
I am having a similar issue with my unlocked lumia 920. While using it with 2G I have no problems, I can make phone calls and the internet although slow, works. Whenever I decide to switch to 3G it can no longer connect to the internet nor can I make/receive phone calls.
The antena cable is new and the signal for 3G shows 2-5 bars (but sometimes it looses the signal. Any hints??

tnx very much for advice, i bought used lumia 920 yesterday and signal was very poor and often without reception then tried this and VOILA, there is now full 3G (H) signal in my room. When you push connector here is a smaaaaaaall *click* and thats almost sure sign it's reason for bad signal.

[Q] Is my phone's network connection dead? Phone dropped...

Hi guys,
First post so please bear with me...
The phone was dropped recently and screen smashed up badly.
Replaced screen and thought all was working fine until tried to make a call/send a message when I discovered that the phone had no network access...
Here's the diagnostic process I've been through...
Wifi works100%
Sim works in other phones
Other sims don't work in this phone.
Checked the antenna assembly to ensure contacts okay
Sim definitely reading - able to read sim contacts
Switched to airplane mode, reboot, turn back on - no luck
Searched for networks manually - no networks found at all. Another phone (samsung galaxy gio) finds all three (Optus, telstra, Vodafone)
No networks detected automatically either
No network detected using 2g only
So, if my wifi is working fine, that should rule out an antenna issue which to me indicates a hardware fault with the network side of things...
Is there a way to verify this is actually the case? And if so, is there a way to repair/solve it without doing a motherboard replacement???
Here was I thinking that it would be a cheap, easy repair... :/

If you want it free of cost so first try flashing new firmware via odin and then check it if not then give it to service centre !:good:
Make sure you're using a stock rom just in case it is a software problem, but it looks like a hardware problem to me. I recommend taking it back to the repair centre where you got your screen replaced.
I don't think it is possible without a motherboard replacement.

thanks
I think I'll do a total strip down again just to make doubly sure that i've got absolutely everything connected in the right place and then if it's still not resolved, I'll look at sourcing a motherboard through some chinese friends...
The phone was actually purchased when in china, and as a result I had to flash it with an Aussie rom to get the google back in android. It's all worked fine since then until dropped which makes me think it's hardware related. problem with buying it in China is that I can't seem to find a motherboard online for it galaxy ace 5830i (the 'i' is the problem... can find plenty of 5830 mobos but seems the consensus is using a 5830 mobo will brick the phone...)
Oh well, thanks for the advice guys.
Even i had the same problem, but i solved it by flashing a stock ROM. You can try that or flash a stok kernel
recently I also had this same problem, even installing the stock rom did not solve, so I researched in several places and saw what could be problem with the IMEI, I did the whole process of repair IMEI and my phone is back to normal , try this method:

Sent from my GT-S5830i
So...
I pulled it apart again to double check everything and noticed that the cell chip had come disconnected from the mobo upon impact and was only attached by three copper strips. After staring at it under a bright light for a while (no magnifying glass was to be found!), we stuck some super glue under it and tried to dry contact all the points... but it still didn't work.
However... after talking with a mate who's into circuit boards, he suggested that I try putting the mobo in the oven at 350 deg for 15 min to resolder all the joints as they use low-temp solder on these sort of boards.
I've got nothing to lose, so will be giving this a try when I get a chance and see if this brings it back!
I'll post back my results.
Yeah, and I recommend using a fine tip on your soldering iron just to be safe.

[Q] No phone or data service unless in AT&T hotspot

Weird issue, I get no phone or data service unless I am in an AT&T hotspot. Anybody know what the issue could be?
Samsung Galaxy S2 i777
I've had the phone about 2 years and have had no problems until last week when I changed out the micro usb port.
Any thoughts are welcome, particularly related to how access within a hotspot is different than outside of one.
Thanks!
Steve
I've come to understand that the micro-usb port for these phones is tied to the network radio antenna, and there are different versionsrevisions of the part available. Considering that the wifi system is not related, it makes sense that you are able to connect to "hot-spots". I've read mention of people finding success after switching to a different "version/revision" (printed on the port/radio) of the unit.
I have also read that users are cutting the board to separate the new USB charge port from the useable data radio antenna.
If I find a link to one of those posts, I'll link it here, but that's my guess.
-Cyril
Edit: Here is the same issue, so definitely related to charge-port replacement...
- This post says that genuine equipment matters
- Here is a post citing success by separating (cutting) the useable antenna from the damaged USB port.
- This page finds success via cutting the board, or using one particular ebay seller. good luck.

Replaced old usb and new antenna -- still no service
Update: I put the old usb port in and still no service (recall that i used to have service with old usb, just couldn't charge).
Also, put in new antenna, and still no service.
Now the question is why would I no longer have service with my old usb?
Are you sure that you plugged that antenna cord back onto the board? The original should certainly give you signal if it did before.
No firmware changes? no apn changes? Was there anything else that you changed recently?
