[Q] 3G advanced configuration (help me please)

Hello there, this is my problem...
I flashed my phone and now I can't make 3G work. I have tried all this:
- call to my phone company and enter the exact parameters in configuration (user, password, server, etc)
- flash with another custom ROM
- flash with the original stock of my country (Chile) (via Odin, from Doky73 firmwares)
- backup from another GT-S5360L and restore in my phone
- enter into the servicemode *#*#197328640#*#*
Nothing of this have worked.
PLEASE HELP ME!
¿DO YOU KNOW A 3G ADVANCED CONFIGURATION MENU?
¿IS POSSIBLE THAT 3G IS GONE FOREVER?

HMM...
Did you try changing ur network mode to WCDMA? If its on auto mode then change it.. if still u dont get 3g or the H sign near ur network then its the fault of ur service provider

yes i tried changing to only WCDMA and I lost the signal.
I put the my SIM in another SGY and I changed to only WCDMA configuration and 3G is totally ok... =/

Maybe your current location doesn't have strong enough signal for your SIM card, try changing location
Sent from my GT-S5360 using XDA

It seems to be a really weird problem.. try asking your service provider for 3g setting FOR galaxy y. If it still doesnt work then ur 3G receptor is not working.

try turning on the packet data, and switch to WCDMA only.
if it does not work turn off packet data, then goto flight mode switch to GSM only and back to WCDMA and turn on packet data again. this also happens on my phone sometimes.

Wifi not showing any available network

Hi, I am on Stock 4.4.3, unrooted,
I have been using it for some days after flashing factory image,, working fine, I moved from One Country to another, and its not showing me any available wifi network, even I saved one wifi network manually but still its not connecting to it,
any ideas what could be the problem? or how it could be restored, I am thinking of a factory reset again, but just curious what happened here, and what if it repeats even after factory reset,

Check in the advanced wifi settings the frequency band. Is it on automatic?

data not working on stock rom but on flyme

Hello all,
I am from Austria and i have a bob-sim-card. It works with the A1-net. So i have to activate data-roaming.
As you see in the title, i have a problem with data connection. It couldn´t be solved with the technical support too, so i ask here for help, because i love my elephone!
I tried flyme and evereything worked fine, but i have all my contacts and apps backup on google, so i can´t use flyme. I went back to stock rom and the same again, data doesn´t work. It shows "U" or "3G" or "H+" in the display and the technical support also see connection, but firefox, wheather app, play store, .... can´t get data.
Does anybody has an idea???
Thanks and greetings from Austria,
Matthias

Try the following:
Go to Settings
select Data Usage
select your Carrier
Activate Cellular Data
Had the same problem (Phone showed 3G but there was no data connection) and this wasn't activated.

Thank you for the tip, it was off! But it doesnt work, with reboot too. I will make a few experiments more with these settings, its a little bit complicated to change sim for looking at xda.
Thanks and please for more ideas,
Matthias

I'v gone to Engineer Mode with *#*#3646633#*#*. CDS-Information says:
Network Information List:
(0)MOBILE()
state DISCONNECTED/DISCONNECTED
reason: (unspecified)
extra: (none)
roaming: false
failover: false
isAvailable: true
isConnectedToProvisioningNetwork: false)
Can anybody read this information? Data-roaming is "on".
There are a few more connections as mms, wifi,... This is the one that don't work i think.
Greetings, Matthias

huh, strange problem you have there - if you really do have to go back to flyme you can flash gapps for lollipop(around 200mb mini version) or whichever gapps package suits you. I did this and it worked fine, also installed nova launcher as hated the miui launcher!
your problem does seem to to do with the data roaming but unfortunately I'm not sure how to force this setting on...

Hello back again,
So there is a solution with installing gapps separat. Thanks for that!
I think the first custom roms are coming soon, perhaps cyanogenmod or something other? This would be wonderful!
P. S. I destroyed my imei with flashing, have to repair, perhaps it changes data-connection too?
Matthias

Not sure about the imei but I suppose it's possible, maybe have to try flyme again then! Hope CM put a rom out for us soon.

I did it!
Hello all,
the phone is working well now! Thanks for all helpers, there were two problems, here are the solutions:
1) When flashing the latest stock rom imei is destroyed. You can solve this with "MTK Engineering Mode" from playstore.
You open the app and go to: MTK Settings, Connectivity, CDS Information, Radio Information, Phone 1.
Here you have at the top "AT+". here you complete to >>AT+EGMR=1,7,"123456789012345"<<, of course with your imei, which ist standing on the akku-cover.
Then, very important: You have to put in a space after "AT+", so it looks like >>AT+ EGMR=1,7,"123456789012345"<<
Click "SEND AT COMMAND". Thats it.
For the second imei do the same with >>AT+ EGMR=1,10,"123456789012345"<<
2) The second thing is that you have to turn on data roaming at two places.
Settings, Data usage, Card 1, Cellular data and
Settings, More, Cellular networks, Data roaming
So, i hope to help at these problems, i´m very glad with this phone now although i have a few more grey hairs.
Greetings, Matthias

Glad you got it working again and thanks for posting the guide from the bbs forum here though strangely my imei has survived through at least half a dozen flashes(probably more actually!) but I may need this recovery solution one day when more roms come out.

change imei
Perhaps a mod can change the title to "change imei" or something similar?
Matthias

Data working
Not sure if this was mentioned but people who have problem with data network 3G etc I seem to found a solution.
Simpler that it seems. You just need to set up a APN in you settings. Never had to do that with my previous phone (Galaxy S3) so it was a surprise for me.
You just need to find the settings from your provider (they usually have it at their website) and then you should be fine.

No the imei is not destroyed per default by flashing, it might be destroyed by a faulty flash.
I flashed mine a couple of times now without any problems
And no, you don't need Data Roaming on (unless you are roaming).
Cellular data need to be turned on though as it's off by default after flashing.
Just to make things clear

Thanks sharkware, i flashed with sp-flashtool on Win7. Good for you when your imei is ok. Mine was not, no problem.
I have to activate data-roaming because i use a provider who has no own net but works together with a big provider.
Thanks for your comment, i see clearer now.

Showing no service though sim is detected

I unlocked bootloader and installed purenexus on my friends N5X.
It all went good for 2 week then the phone was not connecting to 3G,though 2G was okay.I thought it was a temporary network problem.
Then after a day I wiped Data then 3G was back,but then after an hour It showed 2G again and then lost all network connection.
I saw that the IMEI and Baseband is okay so no problem there.
Things I did:
-wiped data cache.
-Flashed ROM again.
-Flashed latest vendor and latest ROM.
-Tried different SIM.
Still no network.
Any help would be appreciated.

Check current APN setting and edit to appropriate input. I personally delete other APNs my phone does not need. I'm throwing a random guess, but maybe it could be from the phone automatically setting APNs upon phone restarts.

[SOLVED] Keep losing mobile service

I'm gonna lose my mind.
Last week I did a factory reset. Everything was great for a few days. Then as of Monday, my phone no longer connected to mobile network. (I'm on Visible, which is a Verizon MVNO.)
I tried the same SIM card in another phone, and it worked — but a different SIM card did not work in my phone. So it must be the phone, right?
I looked at About phone > SIM card status:
Network: Visible
Mobile network state: Disconnected
Service state: In service
IMS reg status: Registered
Signal strength: -113 dbm
Network Cell Info Lite app showed the nearest tower and:
SIM state: Ready
Service state: In-Service
I tried resetting network settings and restarting in safe mode, but that didn't help. Visible said to take the phone in to Samsung repair center.
So I did that. They ran a diagnostic, and said everything was fine. They said try factory reset again.
So I factory reset the phone, again, from recovery mode, wiping with cache several times.
After, service was working. Yay!
But then a few hours later, the battery died, and ipon powering back up, I AGAIN no longer have cell service!
Could it be related to adding a work profile? Enabling dev mode?
Any bloody idea what is happening??
I'm loathe to do another factory reset, as it takes me half a day to set up everything again (Work profile authentication, etc.)
Please help save my sanity.
Thanks!

Try playing about with this app, it allows you to force the phone to connect to specific network bands, possible you could force it to reconnect when it drops out
Samsung Band Selection - Apps on Google Play
This app will help you access hidden network settings for forcing band selection
play.google.com

SOLVED!
I popped in a SIM from a different carrier, causing phone to restart, then put back the Visible SIM, forcing phone to re-retrieve settings.
Whew!

Couldve been a CSC issue?

Congrats to you, but my problem didn't solved yet...
@*Detection* i have tried this app many times but didn't worked for me... maybe i have lost my IMEI & device is just showing dummy IMEI though IMEI is same after & before flashing the ROM but when i flashed the IMEI went to NULL in settings then after applying essential fix IMEI came back it also detect the sim but not picking the cellular network only showing the name of network...
