[Q] No signal problem

Hi all! I'm experiencing a serious problem with my I5800. Suddenly I'm unable to connect to my carrier network, no signal at all. I was using Kyrillios till now, but it is still not working after i flashed a stock JPF. I tried everything, different versions of stock and Kyrillios, clearing data and cache, using another SIM from other carriers. No matter what I do my phone is unable to connect to the phone network. Searching in the forums i found others facing this problem after using Kyrillios for some time... but no solution worked. So basically now I have a "dead" phone... Any help? Someone with the same problem?

Try to choose a different network operator. Go to Settings -> Wireless and network -> Mobile networks -> Choose network operator. Try all options and see if any of em work.

I can see all my country networks, but when i choose mine the popup says registered and after some mins a red sign appear in the bar "No service (my carrier name)". I tried other carriers but I can't use others with my sim. Also i tried other sims as i said of other carriers and they all ahve the same problem. In other phone they all works normal.
I'm wondering if the Kyrillios ROM can damage the antenna or something like that. It could be a serious issue caused by it.

Nah I don't think it does. Not physically at least.
Try flashing an eclair rom, preferably the one which you had originally. Maybe that'll help. Or some ROM, just so you can be sure it works at least with some ROM. Then we can start thinking of new solutions

I tried many eclair and froyo now. It don't connect to the network. No ROM works.

thats can be it. i changed it to all 0 and after some mins it connected. long story short: i won a lawsuit against them for privacy violation (thet had to pay circa 70k euro) so i suppose they blocked my phone bought from them as revenge. (vodafone)

NO DATA?!?!

I changed ROM's and I cant get data back. Ive tried multiple and its a no go. I NEED my data. What do I do? Ive checked my APN settings....help!!!

what network are you on?
have you tried deleting all other APN's except the one you need?
Do you have signal at all / are you connected to the phone network and able to take / receive calls? or is nothing working?

I am on Straight Talk.
I just deleted the other "ATT" apn that was there. Currently only have the ST one selected and present.
I have "H+" in the notification pane and its "blue" meaning what i thought was "active data". But nothing

has the data worked at any point before?
This is the problem that lots of people over in this thread are having ...
http://forum.xda-developers.com/showthread.php?t=2084706&
We are hoping for some sort of fix to this in 4.2.2, but until then we haven't been able to find a solution. If you are 100% certain the APN settings are correct (I can't help with that as from UK so not familiar with that network) then there isn't much you can do. For me, the only thing I ever find that sometimes brings it back is if I turn airplane mode on, leave it for 30 seconds then turn it off again. Likewise, you can click on the APN to reset that each time.
If you are rooted, Faux released a modified kernal which is meant to improve data drops and the wake issue which some nexus's have.

did you cut your own micro sim?
try a spare sim if you have one.
Reset APN to default, delete all and try again.
I don't know what else to suggest other than the above / phoning google / rooting and trying a different kernal and ROM / wait for 4.2.2 update.
(In the meantime please post in the thread linked above, no need for this duplicate thread just for your issue )

rooting will not kill your network connection. that's something that you did. you need to provide a LOT more information in order to have people help you out,
what ROM are you on, what settings did you change, what mobile carrier are you on, etc. etc. this is a simple fix, but we need to know what caused it first. :good:

I also tryed that several times but nothing...
The SIM card can not register to my network has it something to do with the imei??

IMEISV: 01
Kernel version: 3.4.0-1715731

Buildnumber:
JSS15J.I9505XXUEMI8
Baseband Version:

Never give out your imei number

Well the person above me said it. You just made a mountain out of a mole hill by giving out your imei to everyone on xda. Anyway, have you tried a factory reset? If that doesn't work take it to Best Buy and tell them Kies wrecked havoc on your device and they can re-flash your phone for free. Don't tell them it was your fault.

I don't know what the problem is but you should be able to flash the stock firmware in Odin and get your phone working again. Double check this in the i9500, i9505, i9505G S4 forum. You can get the stock firmware from sammobile.com

He should be able to flash it himself. The i9505 is not locked down like the i337. It's an international version so he probably can't take it to best buy, which is what I was responding to.

Data enabled, but no internet connection
Hello,
I have the stock rooted i337 (AT&T), running on another provider network. I am aware that i337 is very difficult to do modifications due to the built-in by AT&T vicious locks to prevent using it with other network providers. This is the reason I did not flash ROM, because I am afraid to get my phone bricked and lose it entirely. Recently I subscribed to a data plan from a third party provider and I have 4G in the status line and HSPA in the data type, but I still did not have internet connection when WiFi was disabled, except that my Hotmail somehow worked. No other apps requiring internet worked. I spent a week researching the issue myself as well as working with the provider's tech support, but nothing worked. Two days ago, almost out of despair, I installed a new app called Opera Max, which is developed to route the unencrypted data to their Virtual Private Network in order to compress it and save the data use. As soon as I connected to VPN, all applications started working. I still have to turn Opera Max off when I use WiFi, because it disconnects my WiFi every few minutes, claiming that WiFi signal is too low. (My signal is very strong and no other devices have any issues with WiFi). However, this is a minor problem, considering that Opera Max saved my data plan.
It is still a mystery to me why Hotmail worked, but no other apps and why using Opera Max VPN solved the problem. If anybody has ideas, I will be happy to hear.
I must say that all data settings, including APN are checked, rechecked and correct, so this was not the issue.
Thanks,
Dan

I am also having connection issues after rooting my S4 i9505:
I am on a Telcel (Mexico) which is supposed to support 4G connections... However, ever since I rooted I can only access 2G/GSM networks. I have the official APN network configuration and I have tried two roms but still no luck...
Any advice would be most welcome.

Resetted APN and lost mobile data stock 4.3

Is the default apn profile the wrong one? I am currently at work and without wifi, would like to fix this to be able to at least make calls. As it stands, I believe nothing works. Texts, data, mms and calls. I am unable to edit the APN as well, which is odd since the default is incorrect. Any way around this? Will updating the prl or something restore my settings?
Fixed by using: "##72786# " to reset the APN settings.Will leave this thread in case anyone else has the same problem in the future.

Thanks! Just got back from Spain and even though I had saved my APN's before installing an Orange SIM card, it wouldn't restore when I got home. I was completely confused and tried several different things, but this fixed it!

Data problems - only 4g, no 3g/1X

I've noticed for a while that my phone's data is unusable any time I have a solid 3g or 1x connection. However, data works fine on 4g. Running NC4 with MJE radio, stock rooted. My wife's Note 2 works fine at the same locations, so I know it's something up with the phone or configuration.
Any ideas?
Thanks in advance.

Have you tried any other radios to test the 3g? Other than that you could check out this thread.

Thanks for the reply. Yeah, I tried NC2/NC4 radios, and no dice. I'll keep playing with it..perhaps I'll switch to Alliance or something and see if some ROM setting has gotten screwed up somewhere.

If you are willing to take the time you could try this. I've done it once and it fixed some residual settings left over from multiple roms.

Finally had a resolution to this issue -
After everything else not working, I took a SIM from a family member and put it in my phone. Data worked fine. So, I requested a replacement SIM from the Verizon store, and the issue is fixed. Not sure what happened with the old SIM, but it was a carryover from an older 4G phone.
It was ackward explaining to the rep what "Safe Strap" was...I mumbled something about installing a few tools to troubleshoot this issue from the Play Store.
