[Q] HELP! GS not conneting to network

I flashed JG5 using Odin (removed sim and sd card) after that i did the modaco r3. Now it does not connect to the mobile network. PLEASE HELP
Did you flash all three files (pda,phone and csc)?
Also, are you talking about mobile network for calls/texts or data only?
Thank you for responding.
Yes i flashed all together.
My Calls / Text is not working...the status bar does not show the connection.
I thought the problem was with the task killer hence that too has been un installed.
I did notice that when i switched sim cards and restarted the network came on but the phone would restart and the network would disappear.
did you install the apn files for your phone .most of the time you find a list at the provider .you can go to apps settings wireless internet mobile networks names and intrance points tip at tapp and tip on new apn .but first find your providers list .if you google apn list ore so you can find it also

Thanks for the reply. Isnt APN used primarily to connect to EDGE / GPRS. Is it required for registering on a mobile network because as of now the phone is not registering on the mobile network.
Need help urgently...hence bumping
Set up your apn again. Trust me

APN---Done that it did not help.
Sometimes i get the signal strength bars but when i dial a number it does not connect it just says Dialing.
This is getting very frustrating.
should i try to flash another firmware...if so please point me to a mirror site as the samsung firmware site is down since the past few days.
Yes, you probably should try a different firmware. Try JM2 from my mirror. (see signature, download is fastest if you run wuala. direct http downloads may be slow at times)

One doubt...are firmwares region specific or anything goes ??
Once i flash i will update this post and i pray that it works
The content of the f/ws is region specific (additional languages and apps that only work in some countries). However, they all work on the your device!

Flashed JM2...same problem HELP!!
Should i format my internal if that is what is causing the problem...because i am not able to figure out the exact problem.
I have the same problem. I bought my GS from USA and I try to use it in Europe. I flashed it both European and America firmwares but I couldn't solve the problem.
When I press *#1234#, it shows that "Phone: Unknown" and *#06# responses nothing.
When i insert the sim card of another operator the phone works. My original operators sim works on other mobiles except this galaxy s. Any tips on why or how to check.
I'm having the same problem, any help to fix this would me really great!
It seems that the galaxy s is not connecting on 1800mhz after flashing. It connects on networks using 900 mhz. Any way to check this on the phone
This is weird. I tried using the phone from another location and it worked. I think this has to do something with the cell tower near my home location.
Hi guys,
I was able to re-flash the original firmware and all works again. If you guys want to go that way here is the link http://forum.xda-developers.com/showthread.php?t=734475 I think this is just for the Vibrant but I'm sure you can find the other firmware on the forums.

[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.

No 3G after flashing, only EDGE

Hi !!
Looking in the forums, i have seen this problem in other models
The solution, normally, is to reset the APN settings to default (haven't worked for me)
flashed to stock firmware ... still with EDGE
Someone have experienced the same problem ?
Try a factory reset

u flashed back to stockrom using odin?
i have no idea bout this problem
but if you flashed stockrom using odin and did hard reset should fix the problem.
make sure its not about a network trouble from the provider
you might try this...open setting>wireless and network>mobile network. untick use packet data. network mode, choose wcdma only. tick use packet data.

This is what i've done
1- Flashed to an Indian firmware version, no backup (my mistake). From that
moment, losed 3G/H connectivity
2- Flashed various firmwares, no success
3- Thanks to Doky, i was able to get the original firmware of my phone, installed it and change the country via *#272*_your_imei_# and reboot
4- Still with EDGE ....
In a previous flash, i used the "WCDMA Only", but i lost my mobile network .
Going to test in another phone to see if it's a provider problem .....
Thanks for your help ...
when i used "WCDMA Only", my current network changed (i'm from Colombia, my SIM is movistar, changing the setting changed the current network to Tigo) ....
based on your explanation, it seems that you have bad signal reception dude...

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.
