[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.

[Q] {10-25-2012}{Rom}{ICS} Official Global CM9

* Unfortunately, I'm having the same problems with this ROM on HSDPA that I was having on aeroevan's ROM. GSM is found immediately on boot, however, HSDPA is very flakey. It will succeed in connecting every now and again, but then randomly drops the signal and won't reconnect. I thought maybe I just had a weak 3G signal where I was testing, but I have a BB Bold for work as well and that can easily maintain a 3G connection on the same network. I also had no problem way back in the day with CM7.2, but that ship has sailed .
Also, when the phone is in WCDMA preferred mode, after a while the phone will lose all connections (usually after a reboot but not always), including to GSM and when I go to reselect my network operator I get the message "Error while searching for networks". No matter how many times I reboot the phone or switch to "GSM Only" or "GSM/WCDMA auto" it never lets me again select my network provider.
As I said, I ran into the same problems with aero's port, so its not specific to this ROM.
* Situation are me after uproom (http://forum.xda-developers.com/showthread.php?t=1932573), spent two days lost wave, down to the original room (fullwipe finished down about 2.3.4). So lose the 3G network always in global mode (global), 3G users they will never be, but 2G ok (you spend vina sim and have installed APV vina). The physician who has experience helping hand factories. Thank a lot.

BTW, I don't understand this part.
I would suggest reading through the entire thread of Aeroevan's rom that you were describing as well as the Global CM9 thread. During your reading you may find and answer in there. I have found more answers that way than waiting on someone to direct me there anyway. That is all the advice I can provide with my limited knowledge.

Help me

I reinstall the original room 2.3.4 but only use 2G when I used dataroaming; completely unusable 3G & network global mode always (I fullwipe data before reinstalling room 2.3.4 & APN properly installed).I then set your room again, but as I said above condition.Please help me how to be able to use 3G

Ok, I don't know if anyone else is having the same problem as you. I hope I don't offend you but I am going to take a guess and say that english is not your first language as some of that is difficult for me to read and completely understand. From what I am gathering is you can connect to your carriers network but only on a temporary basis. Here are the steps I followed to connect to Verizon's network using {10-25-2012}{Rom}{ICS} Official Global CM9 - After a full wipe and clean install and after initial setup I went to (doing this from memory as I don't have it installed at the moment) Settings --> More --> Mobile Networks --> chose CDMA w/EVDO --> Exit out of settings and rebooted. When the phone booted up it recognized the Verizon network and all service and data was all working, I didn't have to change the APN settings at all. If you are still having trouble staying connected I suggest you check the version of radio you are using and consider updating it. Here is the radio thread: http://forum.xda-developers.com/showthread.php?t=1134451 I don't think I am the best person to assist you but just telling you what I would do if I were in your situation.

3G disconnect, only use 2G (GSM). Help me!

I have been having the same problem. Flashed CM10 after full wipe, mobile network (for verizon) is CDMA w/EVDO, tried rebooting and switching and wiping and re-flashing but I have no wifi and bad 3G. When I revert to stock everything is fine. How can I fine the latest radio for CM10, I didn't see any JB in the thread link.

[Q] Lost Data Signal

I recently (1 week ago) flashed Paranoid Android's latest ROM (3.99 I believe) and have been running flawless since the flash. However, this morning my phone hasn't been able to pick up a data signal. I can connect to WiFi and also can receive calls (I am getting phone signal), but no data is working on my phone unless I connect to a WiFi signal.
What I've tried:
- rebooting the device
- updating profile and prl
- rebooting to recovery and fixing permissions
- rebooting the device
- toggling wifi and data (on/off)
- rebooting the device
Did I mention I rebooted the device? Nothing.
Any help here?

Is data even enabled? Check and uncheck, reboot (Settings > Wireless & Networks > More > Mobile Networks > Data enabled)
Do you have a data usage cap set?
It sounds like Sprint cause of the profile/prl. I've had outages for my area before, luckily my personal phone is on AT&T...

Thanks for the suggestion, unfortunately I've tried it already. I do not have a data cap set on the phone. I'm hoping it is with Sprint and not anything too complicated. If other co-workers have Sprint and their data works, would that indicate that it is on my end?

The data issue with sprint is because its a 4.3 ROM, and data with those ROMs( on sprint ) is hit or miss. They're getting better, but not 100% yet. Just flash back to 4.2.2 and you should be fine

Lolipop problem with 4G LTE

Hello
After reboot phone setup wcdma/gsm network priority. There is also problem with changing to lte/wcdma/gms , you cannot click it directly, need first click like gsm and then lte to make it active.
Using official lolipop , IL customization
Anyone noticed 4G/LTE problem on Lolipop ?

I'm having the same problems, but I finally get LTE working

Same for me. But I don't have LTE yet. So didn't bother too much.

maybe you can try this:
FIX 4G PROBLEMS
edit build.prop
- look for 'telephony.lteOnCdmaDevice=0' and change it to 'telephony.lteOnCdmaDevice=1'
look for 'ro.semc.version.fs=GLOBAL-HSPA' and change it to 'ro.semc.version.fs=GLOBAL-LTE'
reboot your phone
type *#*#4636#*#*
Select phone informations (first menu)
turn off radio
in network prefered I've selected TD-SCDMA, LTE, CDMA, EvDO GSM/WCDMA
turn on radio again
exit
type *#*#4636#*#* again and look in network prefered, it will be on LTE/GSM auto (PRL) and 4G should be there

LTE/4G issue after hard reset
Hi to all,
and thank you for the tips doenen.
I have the same issue since i hard-reset the phone.
Just to be clear, if we want to edit the build.prop file, we have to be rooted ?

Hi, I did all the steps except the ro.semc one, because there is no such setting in my build.prop. However I still wasn't able to get 4g working, it just keeps switching back to the old settings.. Any ideas? Running cm12.1 android 5.1.1

Re issue with LTE/4G
Hello,
i got my phone back from SONY's technical services, cause i had a bunch of issue (i sent it twice in a month).
For now, the battery drain isseu seems to be fixed, but i do not have 4G/LTE.
I already encounter this issue, and after the service menu manipulation, everything got back in order.
I tried to do the same manipulations, but i can't turn off radio. It's like it was locked.
Any ideas ?
Thanks for helping.
Regards

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.

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.
