[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

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.

[Q] 3G mobile data is not working

I've flashed Xperia Z Jelly Bean v4 (this one http://forum.xda-developers.com/showthread.php?t=2267230&highlight=data) on my Arc S and I can say its so fast and so beautiful.
The only problem I have is that I cant connect to mobile data 3G however my APN settings are correct
I flashed BB-77 too as recommended by one of the users in the thread and it didnt work as well
So what should I do now ?
Thanks

Were you able to use the 3G connection before this ROM?
My current advice - Ask from your operator, if the 3G connection is enabled for you.

Are you sure you have "Data enabled"? Try to reboot your phone.

Yes I was able to use 3G before this ROM and i contacted my operator and 3G is enabled already
Does that have anything to do with the baseband ??

Well, if in the thread you downloaded it from was nothing more to flash, then nop.
I said it because in GB Roms you must flash an additional libraries, but i dont had used CM10 based ROMs so i can just can guess, check the baseband threads.
By the way, sometimes my phone "losses" the data connection for a while (the icon dessapear even if the data connection is active). It just happen like 2 times since a got it, but after some time it comes back.

Flash latest stock 4.0.4 and then install Xperia Z Jelly Bean v4.

Well, in the thread I flashed something called Xperia Arc S 4.1.B.1.13 Vodafone DE firmware and they said it's for increasing system and data memory for Arc user and latest BB. You think this is the problem ?!

the phone is not set to gsm only?
look at settings - more - mobile network - uncheck 2g
also look at the accesspoin and choose the right one

Guys please this is really urgent and I did everything I could
Last thing i did was flashing every stock thing on the phone, stock GB, stock kernel, stock baseband and nothing changed and data mobile is still not working

You can try to input the apn by yourself

eXistenZ ROM network data problem

Hi,
I am new to android, recently bought a Sony Xperia ZL, great device, and I decided to root my phone and try out a Rom. I tried the eXistenz ROM black edition, and it was awesome. However, I tried it while I was at home, using wifi, but this morning I had to head out and tried to use my Data and it didn't work. Tried enabling 4G and LTE, and both options didn't work, the ICONS did not show up at all.
I had to revert back to stock because I urgently needed internet access.
Anyone run into this issue? I tried searching the forum, but no luck.
Not sure if this will help, but I'm on a locked bootloader, model C6506, Android 4.2.2, Build number 10.3.A.0.423
Anyway, looking for any advice so that I could give it another shot.

Toggle airplane mode ON the OFF, now turn Ur data ON.
or
Restart Ur phone then turn ON data.
I'm having the same issue with other custom rom. I noticed that when ur data works after restart or toggle ON/OFF airplane mode u can toggle it ON/OFF without problem, but when u start turn wifi ON/OFF the issue start that sometime ur phone can't connect to data.

Thank you for your response. I had tried a combination of that before posting lol. HOWEVER, I did find out the problem. Apparently, with my provider, and the ROM, the APN was removed. I had to add it back in manually. I never ever used an android before, so I didn't know where to begin lol.

Network Signal Dropping after update to 6.0M (Poland)

When i bought D855p it came with 4.4, then i updated to 5.1, all official. After this i installed Cyanogenmod 12.1 and everything were fine. But when i installed 6.0(poland) my network signal keeps droping the intire day, it changes to UMTS and HSPA. I cant use my phone as a phone. The only way to solve this is, every time that i turn off the cel or put in airplane mode, is enter in MOBILE NETWORKS > NETWORK OPERATORS > SEARCH NETWORKS and choose GSM. (but i need to do this EEEEEVERY TIME that my cel turns off/airplane mode).
6.0 is the only ROM that i can choose GSM and the signal keep ~stable~. At least i can use my phone as a phone !
I did a backup of my IMEI before installing cm12 as well.
Things that i already tried :
-Flash ALL modem (ALL) , including 21C.
-intall cm13 and after cm12. Using TWRP 2.8 and 3.0.
-stock 4.4 , 5.0 , 5.1 and again 6.0. Using LGFlashTools
-MANY factory resets and wipes !
anybody can help me ? :good:

Same issue. I am on stock 4.4 and mobile network signal keeps dropping on weak signal area. I set to gsm/edge mode to mobile network. But nothing goes fine.

Try this. However in your case download the Polad specific .kdz files

Doesn't work , sadly :crying:
i also tried to put in Network mode : GSM/WCDMA ( worked ) but when i choose GSM/WCDMA/LTE auto , signal drops every time. It is a solution to do this, but i cant use my LTE, and it sucks ...

Disable VOLTE n go to ur models service menu (check google) for me it was
*#546368#*851# (my model = d851)
*#546368#*XXX# (ur model=D8XX) verizon sprint numbers are differently
go to field test >network mode>set GSM permanently (try different gsm 850,990,etc)
Back > RAT selection > select GSM
U cant have network problems now cuz ur permanently set to gsm dont use 3g or 4g use wifi
hit like it helps

I'm sad to hear that. Try also flashing modem 21C. There are also other guides for restoring your signal around the forum, different things seem to work for different people.
