[Q] CANNOT connect to any wifi networks!? HELP! - Captivate Q&A, Help & Troubleshooting

Hey guys, I am not able to connect to any wifi networks not even my own. The phone is able to locate the wifi networks near my house, but when i click on it, it prompts for the WPA password, but the "connect" button is greyed out. I am not able to click on it T_T. So all i am able to do is enter my password and thats about it...
EDIT : This occured as a result of me manually upgrading to 2.2 firmware, if that helps anyone.
EDIT 2 : Also, there is a slight scratch on my sim card now because i may have took it out inproperly. I dont know if thats the problem
EDIT 3 : It seems like i fixed the problem, but my 3g network is still not working >_>

Aww anyone ? D:

Have you tried through settings as apposed to the notification bar
Sent from me

Yep i did it through settings. And I also noticed that my 3g network isnt working either. It shows 2 full bars/ 5 bars, but i cant go to any website. It wont load.

Can anyone help me ? D:

Have you rebooted since you flashed
Sounds like a modem problem
When you flashed did you remove your sim
Sent from me

Yes I had nothing in my phone except my b attery when i flashed. Also, my modem is fine otherwise i wouldnt be typing here

Also, there is a slight scratch on my sim card now because i may have took it out inproperly. I dont know if thats the problem

I was referring to the modern in your phone
Can you make phone calls
I have never flashed ji6. If you can not resolve I would suggest flashing back to stock. From there you can try ji6 again or try s custom 2.2 rom

Yep i can make phone calls.

help cant connect to network or save proper network or sms settings

a quick history of what I've done so far
Sumsung I897 captivate from ATT unlock and being used on Telus network was working great for about 4 days, then all kinds of problem started cropping up.
Phone came unlocked, I rooted using update.zip from xda, installed rom manager and started removing ATT bloatware, entered SMS and APN info which worked fine.
Yesterday I noticed that where I once got good reception I was now getting nothing and would have to drive down the street before I would get something descent. I thought maybe I'd put it back to stock with rom manager and see if that would help which it did not. It actually made it worse, decided to go all out and use the Odin3 one click downloader just to make sure I was back to stock firmware. This didn't work either but now I can enter the SMS and change the preferred network type but it doesn't save. Preferred network type is grayed out and even though I can change it it never save same as SMS.
Now I can't hold connecting in my living room where my wifes Milestone gets full bars. I tried taking the phone to where I had the best signal and change the preferred network, SMS, and set the network operator but it doesn't save any info, can't find on operator half the time on manual or auto and gave me an error and logged it to #*9900#
I've been at this for 2 days straight and can't figure out how to get it right back to stock, it seems to keep hanging onto the same preferred network and not saving anything I enter.
What can I do to get back to stock, and it has to be something that wipes everything clean, clean, clean, because even the GSM disconnects stay logged under *#*#4636#*#*
***I desperately even tried pulling the batt and SIM card for the night in hopes that would do something.
So, if I'm understand what happened correctly, you bought an unlocked Captivate, rooted it, deleted some bloatware, entered your Telus APN info and everything worked awesome for about four days. Now everything has gone down the hole. Is that right?
If that is the case, then we need to figure out what changed. Using Odin3 would have definitely put you back to stock/unrooted your phone, I don't think you could go back any further than that. If I were you, I would act like I first got the phone. As in, I would do everything you did to it, as if was day one. At one point, everything worked fine. Try to recreate that. You can always look into exchanging it or perhaps Samsung customer support can give you a little more insight to what's going on. Here's the number if you want to try them out.
Samsung customer service - 1.800.726.7864
Thanks, I've gone through the process a few times today from start to finish trying to figure it out ... maybe some of the problems aren't real problems and just limitations that I didn't know where their. I've since flash with odin3+re-partion to the bone stock i897UCJF6 as in not the one click method. It loaded fine but still have the same issue, I can't set preferred network type or get it to keep the number entered into SMSC. I think if I can get passed that I'll be be one the up side of winning. I keep noticing that the log of GSM disconnects never clears or the usage statistics under *#*#4636#*# , I'm thinking its in the same area that other bad data is being held onto instead of being cleared when flash firmware or factory reset.
Is anyone able to change preferred network type? maybe I was never able to change it but I think I should be able too.
I may be wrong in assuming this but I don't think ATT is going to be interested helping me connect one of their handset that I'm trying to use on foreign network, but I could be wrong and is an open option.

used this to lock my phone to WCDMA only so that problem is solved
*** never mind posted to soon it still didn't stick after rebooting
be carefull using the service menu as I have no idea what most of this stuff does
I got the SMS service number issue fix by taking out my sim, swapping in another known working sim from the same network, setting the service number, pressing update and then swapping back. Before every time I tried to update the service number it spit out an "update error" can anybody tell where the SMS config data is stored? on the phone or sim.
The only problem I'm having now is with reception which maybe fixable if I can set the preferred network to WCDMA only. But the button for that option is a light blue colour vs other phones that I can change this setting on. Does the blue mean anything like a locked function or something that set by the firmware as unchangeable?

WEIRD! Emergency call only! O_o

This one is pretty *beep* up! The phone was working pretty fine last time I looked at it (30 minutes ago), I put it in my pocket and had dinner (as always), then I took it out to make a phone call and it says just "Emergency call only" instead of showing my phone operator (3 ITA). I tried rebooting, no luck! Still the same.
Strange thing is that it has signal (full) but I can't make/receive calls or use data network. If I go under Settings -> Wifi -> Mobile networks settings and I look for operators it searches and I can see all of them (mine included) but I cannot select it!! Neither mine nor another one (TIM, which is the roaming default one for my operator when there's no signal)...it just says "Unable to connect. Try later".
Weirdest thing of all is that I AM RECEIVING PUSH EMAILS from gmail!!!
Anyone has a clue about this??? Has it ever happened to anyone?
Btw, I'm using zeroblaster rom, which is based on official italian froyo firmware...everything was working so good until ten minutes ago!
Hope I don't have to reflash...
Just got weirder: put my sim on another phone...it registers without problems on the network.
Then put the other's phone's sim on my sgs...it registers without problems.
Then switched again: Emergency calls only
WHAT THE ****??!? (what are we? children? sorry mod...lol)

It is WAY weird imho! The weirdest thing being that I'm still receiving gmail's pushes after 5-6 reboots while it keeps saying "emergency calls only".
Also I saw that when the phone boots, while it's loading the launcher, widgets, etc. it gets the connection for like 2-3 seconds it shows my operator (in the lockscreen), then it switches to "emergency calls only"...
I'll wait another hour (maybe as the issue came out of nowhere it'll go away? ) then I'll try reflashing...since I had to change to k9 anyway to fix the /system corruption etc. -.- I'm already backing-up...
Hope the flash will fix this though...it's really a pain in the ***

No that's not it, because putting H3G sim on another phone WORKS!!
And anyway, when H3G's down it uses TIM as roaming...this time I cannot even select TIM as operator, it refuses! And normally you can always use tim in roaming if you want (even when H3G has signal...)!

Hmmmm... That is weird alright.
If you purchased your SGS through your carrier H3G I would still call them to report it as there are now 2 of you experiencing the same issue so it cant just be phone related and if it is then they will have to honor your warranty to replace or fix it (both of you)...
It's happening to me too.. i also use H3G Italy on my Galaxy S and i have this issue since around 19:00 this evening with my work SIM card
I have a Tayutama 1.0.0 ROM based on the JPM Froyo ROM.. it's the first time this is happening to me..

Well... That is 3 of you so it must be carrier related in some way. Again... Call your carrier and explain what is happening. Explain that when you put the sim into a different device it works ok but in the SGS all you can do is make emergency calls and they should be able to tell you what is going on.
Make sure to post back as I am now interested in seeing what your issue is / was...

mobile network state: connected (and it works... )
but ... int the status bar it shows "Only emergency calls"...

You just answered your own question I think. "service state: out of service" says it all I believe even if the sim cards DO rgister on another phone for whatever reason.
The fact is the they dont register on your Galaxy S so call them and report the issue and they should be able to help you...
Yeah well, you see, that could be a problem because...H3G has a TERRIBLE customer care, lol! Basically the thing is you can't call them...you need to send an email, and an answer will arrive 2-3 days later. That's not good enough for me! If it doesn't get fixed tomorrow I'll go directly to a 3shop and they'll call someone higher to understand this. Hope they fix it soon though!
Anyway...now I have a strong curiosity: could it be JUST the SGS? If so...WHY???? I tried putting the simcard on a Nokia E71 and it works...does anyone have another android phone with H3G? Could it be somehow "system"-related? Because I can't figure out why a specific phone device shouldn't work point-blank with my operator! And that's even a phone they sell themselves!!
Rebooted and now it WORKS! THANK GOD (even if I'm atheist....)
Still would like to know why it did this!
I had a similar problem where if I was in an area with bad reception it would default to emergency calls only. But the funny thing is when I go into the menu settings I can see my carrier and when I try to select it, it says network unreachable. Eventually I would get signal but the tab still says emergency calls only. Tried making calls but it wouldn't allow.
Initially to rectify the problem I rebooted the phone and that worked but got annoying. So I realised that if I left it for a couple of mins whenn it had reception it would fix itself. As of recently (last 2 months) I haven't any problems.
Btw i'm on jpm and my carrier is 3 australia. It's rubbish service

Hello,
Same thing happening to me... It must have something related to signal strength, i went downtown and phone was perfectly fine.
But at home it keeps loosing signal, i dialed *#*#0011#*#* and it shows changing BAND... as if it was searching for service on different bands...
But the thing is, i tried inserting the SIM on other 2 phones and i get a FULL signal, so i guess signal is coming pretty intense here... why is the SGS loosing it? i have no idea...
By the way, i am from Brazil, and that started happening after i flashed my rom to FROYO VJJPA..
me too, has no signal at home but works for another phone.

[Q] Fed up with Galaxy Ace

Hi Team,
I have heard lot about this forum and hope to get some gud suggestions from you guys.
I bought my Samsung Galaxy ace GT-S5830 with android 2.3.6 Gingerbread OS 6 months back but slowly I started facing few problems when my friends noticed and told me that your phone sometimes says switch off.
I also realized that sometimes even if the airtel network is there still i get an error message that mobile network not available I had to switch off the phone to get it normal.
Again people text me but it goes on pending and gets delivered after hours. I showed this problem to the service center they flashed my mobile but the problem persist I also tried changing my sim card but still all in vain. Now i am literally fed up with this phone.
Please assist me I dont know wat to do :crying:
Note: The phone is not rooted.
Thank you
err, are you sure this is because of the phone..? not the network..? because i never face any of the problems you mention..
may be you should try flashing stock rom with newest baseband for your region, find it on sammobile..

He said the service centre guys reflashed the rom. but agree that the sms thing could be network problem.
Faulty battery/pins (Switch offs)
Faulty hardware (Antenna?)
That's all I can identify.
Hi Guys !!!
Thanks for sharing your views
@demiorkan
The mobile automatically does not gets switched off but i need to do it manually as it keeps on prompting the error message "Mobile network not available" though I can see full network on my mobile.
I would really appreciate if I get any suggestions from your side.
Let me know if any more information is required.
If you dont mind you could try flashing another stock rom and see if that works out. If it did not, then it's probably a hardware problem OR the network (as mentioned). Try your SIM card on another phone as well, that should prove if there is problem with the network or not.
Mostly it might be a firmware problem. Service center might not have flashed a new firmware but simply wiped and gave back. (can't be sure on that). So I recommend on using ODIN and flash new firmware. Google is your best friend on this.
Secondly about the network, Turn on flight mode once and turn it off, you'll get the signal. You can even do some debugging by going to the testing menu (*#*#4636#*#*) and toggle the radio and the preferred connection type and stuff. But if the place where you are is such that you get low signal, then don't try any things on phone as it's ultimately the network problem. Trust Me, the place where I stay, I rarely get proper reception and Even I'm on the same network. Flight Mode trick saves the unnecessary reboot.

[Q] HELP: Lost cellular data and service

Anyone have a fix for this? On Verizon and after almost 4 weeks I have lost my cellular service and data. I noticed when I went to check up on my phone right now that it was finishing a boot-up screen and then never had any bars at the top. Dug deeper and found no service at all. Wiped dalvik and cache and seemed to be bars for under a second and then gone. I am on sensei kernel and am thinking about doing a factory reset and reverting to stock kernel. But I really don't want to lose the benefits it came with.

Well, this is odd. After a month of perfect service, I suddenly cannot get LTE, only 3G. Even nandroids of prior ROM's will not boot into LTE. Is VZW LTE down or should I do a total clean reformat? i do have factory images and everything is backed up. Just a pain.
Very strange. I was flashing various ROM's (CM 12 based - am testing for someone) and at one point pulled out SIM and replaced it. I checked to make sure it is seated right since then. Again, no longer get LTE.
Was on Sensei kernel as well. Let me try flashing stock kernel from ROM first. EDIT: NOPE! Flashing the stock kernel from the ROM did not do it. Looks like total reformat/flash is next!

I just got my Nexus 6 and I am also on Verizon and had the cell coverage drop too. I backed up my apps with titanium backup and did a factory reset and signal came back. I only had it for a day and went to Canada and on my way back to the US I noticed the cell bars were gone. I was just rooted and boot loader unlocked and otherwise stock. I read online that others had this issue when they got to places in the US that had little or no signal. I also noticed that under cellular network settings it loads up with Global under the preferred network type even though it has an option for "LTE (recommended)" and if you choose LTE, global is never an option again until you do a factory reset and it loads with it pre selected. With global selected it works perfectly with calls and LTE, so not sure what that means or if my selecting LTE made it drop the signal after going back from Canada.
Yep, total flash of factory image fixed it. Sigh. Early enough in the day for me to get everything set up again.
Same. About to do it too... I've done too many factory resets with this already. Kind of annoying.
I am in the same boat. Had no problems until I flashed bliss 1.5 then was stuck on 3g. Tried a clean flash of Slim and still stuck on 3g. I will try a stock rom but I am not very hopeful at this point. It's looking a like a reformat here as well :/
Ended up having to format everything and start from scratch again. I'm running a stock ROM now and in weary to try another cm ROM
Don't know if it'll help, but try LTE Discovery app in the Play Store. I use it from time to time to reset my data connection.
Having the same issue, running CM12 daily, have been for a week or so. Midday today it drops LTE, 3g data was working, then a few minutes later to no data. I didn't change anything, nothing new installed. I did reboot the phone at some point before this but that is all...
My only fix was to backup via trwp, restore stock rom, factory reset, reboot & let sim activate, then restore cm12 via twrp... it's a 20-30 min fix all said and done.... pita
Maybe its something Verizon is doing, because I didn't change anything and then next thing you know no data. I hope it's a simple fix for CM12 but I see this popping up more the last few days. Hopefully someone will figure it out. I like CM and prefer it over stock but I am not going to do this multiple times a day just to keep CM...

I just checked and global is still an option for me. I've bounced back and forth, looking to see if anything changes..
Same thing has happened to me last night, lost connection to VZW cell and data. Looking at the field test menus, it seems like the SIM/device understand GSM but NOT CDMA anymore. So I believe the issue has something to do with that. Tried everything, but will nuke and repave most likely....also lost Global as well. and LTE Discovery shows GSM stuff nothing for CDMA
Tried the SIM in another device and it works so its not the SIM.
OK I tried a world of things to recover like some of you may have....its something in Userdata because if I flash everything but userdata it wont work. I am going to try and recover from the backup I had before this happened to see if that works....otherwise rebuild from scratch
will post back
UPDATE: So restoring a backup seems to be ok once you get the SIM back.
Having the same issue over here as well... After a month or AI of having the 6, now I randomly drop service where I would normally have full LTE. I almost NEVER get LTE now and am at most on H with a couple bars then it drops out again. Have also.noticed WiFi connection is very shakey.
Any one find a fix?
I had an issue where i couldnt get my phone to connect any network. Took me long rime to realise, that entering my PIN-number too fast caused the issue xD it unlocked the sim, but didnt let me connect any network... Dunno if this helps anyone, but definetly the most cryptic issue I've ever had.

Troubleshooting my wife's N6 here. Your PIN issue doesn't make sense to me because the phone should be connected to the carrier when locked. Are you talking about WiFi? Because that should be connected too when locked unless settings have been changed from their default (ie, turn off wifi when locked/asleep or something)

I'm talking when you turn on your phone and it asks for pin number to unlock your sim. Some how it seems that if you enter your pin too fast, it bugs the phones radio somehow and you can't connect to your carrier but if you wait like 5sec before entering the pin, it connects to the carrier and the (!) Mark goes away. Try rebooting the phone and see if it helps? Even I think its a weird issue
Edit: OK, just pinpointed MY issue. I have to wait for the "no service" text to change into "emergency calls only" before entering my pin or I don't have any service just the exclamation mark :/

Thanks. I told her about it and she will give it a try, or just remove the pin altogether as a test. It is a weird issue. She is missing important calls from her elderly parents at night and it is rather frustrating. Turning wifi off also seems like a bad fix.

Try to keep your phone in 2g only mode. When i keep 3g only only mode i sometimes can't receive call from other party. But 2g only mode solved my problem....
Sent from my C6602 using xda app-developers app
How do I shift it to 2g mode?
menu->settings->more..->cellular network->network mode-> Only GSM
PS. type: *#*#4636#*#* and check in "phone info"
signal strength
GSM service(if enabled)
In old galaxy spica I had similar problem and I had disabled GSM(dunno why) and after second full flash of fresh stock ROM It was working again.
its not helping
I tried everything possible.
So maybe we start from beginning...
Few quick question before we can help you:
1. When those problem started?
2. After what? did you flash custom rom or Kernel ?
3. You had any app/script that could modify your phone?
4. You had ANY hardware problem before?
5. Your phone fall to the ground?
6. Did it have any contact with water?
7. What system do you have now.
8. did you check sim slot?
9. do you have signal strength in this menu that i post earlier?
1. This problem started a month back
2. It all started suddenly, I am on the stock rom without root
3. No I dont have any app that can modify my phone
4. Yes I had a faulty battery problem which was fixed
5. NYes once it had but it was a long time back before the problem started.
6. No it did not have contact with water
7 I use the stock android 4.4.4 kitkat
8 Yes I have checked my sim card slot, I have also replaced my sim a couple of times
9. Yes I have signal strength -79dbm and 25 asu
My sim works well with my other phones. Is it a hardware issue?
I think Im getting a clear view of the problem, my phone isnt able to shift from 3g to 2g I guess. I came to this place where only 2g works, I had my network mode setting as Wcdma(preffered)/gsm, its reluctant to shift. Is it a hardware problem?
Hmm.... If you have signal and phone see network its not hardware problem. To be honest its more like system or more specific kernel problem in 4.4.4 I say this because you ares sixth person who i know that have network problem in 4.4.4
For examle after flashing kk on my phone i have looooooots of reboots if i have 3g network on, and my phone swith to 2g if its in sleep mode.
My friend also have problem similar to yours but it cant use phone function if its have LTE enabled.
Best part is that when he flashed 4.3 problem is still there, but he didnt had it before when he had 4.3
I cant flash any other system now(i use phone too often )so i dont know if i also would had this problem...
So if you can, you could flash even 4.2/4.3 full clean rom and check, just to be sure. Its a bit "extream" downgrade but flashing it and checking its max 1h...
Probably like always its small weird bug or specific system setting problem, maybe different region rom...
So for now you could check other rom, even branded and downgrade to your old 4.3 to see if you still have such problem.
Seriously its a relif that its not a hardware problem yet.
I also flashed the lower version of the kernel. I am facing the same problem . I use the local region ROM only,
I think Im gonna give up on sony now
Hi there
You are not alone, I am also facing this issue and do not know how to resolve it too.
Sometimes when I try to call (full bars on) it makes a bipbip then Call not possible...
Same issue while switching from GSM to H... Most of the time I have to reboot and let it settle for a while.
I am suspecting my network provider
Sent from my C6603 using XDA Free mobile app
I called up the service provider, it seem to get fixed for a day but again the same problem continues
I'm tired of this, the phone guys can't do anything and neither can the service providers
Such an irritating bug by sony
Did anyone get a solution to this problem?
This is very annoying
Same problem,posible solution temporary.
