try reset default. shut down. plug batter abt 5min. boot up. it should work if doesnt work then
use odin downgrade to 4.1.1. check again. if no prob, either OTA upgrade to 412 or use odin to upgrade to 412.
if both doesnt work, bring it to service center.

thanks

Yeah i have tried all possible things wiped everything flashed many stock roms 4.1.1, 4.1.2 and customs roms too couldn't fix it exactly what could be the problem why i have to refresh network signals after reboot to get the signals bar, my IMEI number is correct, baseband is there too

It may be some faulty hardware, if you used custom roms and still you got the problem.

I don't have that problem... i don't understand why you have that problem. I have bmd2 baseband...

i don't want to open new thread as i got the same problem like @Shashan just want to share that you are not alone.
i got LTE sim cannot use it cos in my area is no LTE support .
so i want that my phone is also on GSM or GSM/WCDAMA but it doesn't stay on that it will return auto back to LTE/GSM/WCDAMA and the problem stay no signal there ,
try every think 4.1.1 and 4.1.2 stock and custom ROM no luck here so i think it is hardware problem and the only solution is service center..
just to let other user know ...i did not brick my sgs3 i9305 and never flash wrong ROM. like many other user done before i9300 rom on i9305.
next week i will send my phone to service center it take max 14 days till i get my phone back repair or Brand new .. let see

just want to add this that in max 3 days i get my sgs3 back ...from service center ..cannot say if they repair or they send me new one. so let see cannot wait for it.

@Shashan.
Finally i got my SGS3 LTE back today from service center the don't send me new one they repair it ... what they do is they changed the motherboard on SGS3 LTE.
after test around 4 hours no problem with network and finally i can use my phone ...
so your choice is also if you want you phone to run as a phone too not just PDA then send to your near Samsung service center ..

I have the same problem. My I777 is running the Shostock3, whenever I set "GSM Only", it always get back to the "WCDMA/GSM" after a reboot.
I don't want to change the ROM or kernel, so is there anyway to auto-run a script to active the "GSM Only" right after the phone start?

My I777 is running
wrong forum ??? this is i9305

[Q] No LTE option ( C5303 )

Hey guys I am new to xda forums, I recently bought the xperia SP ( c5303 model ) and I have this strange problem.
When I go to network mode I only get these 3 options WCDMA only GSM only or WCDMA/GSM auto and no LTE or whatever option...
First I thought it was a provider's problem or something but I checked that my 4G connection is enabled from my provider for my connection..
So I went to a store that has all the devices for exhibition and checked another xperia SP and found out that on that one (which had no SIM or internet connection on) that If I go to the settings there I could find all 4 options ( WCDMA , GSM , WCDMA/GSM and LTE/...) . So propably its something wrong with my phone or I dont know..
I Contacted Sony support on my country they told me to factory reset the phone and if that dosnt solve it repair the software or whatever with PC companion ...
I did both and had no luck on finding a solution, so I thought to ask you guys ...Help if you guys have any clue on that
P.S Just read a related thread http://forum.xda-developers.com/showthread.php?t=2331317&page=2 and did this
To check:
Go to the dialer and enter;
*#*#4636#*#*
Click on Phone Information
Scroll down to Set preferred network type and check if LTE is an option
Found it but still cant select it so my question is .. Is something wrong with my device or it has to do with the provider etc ?
Thanks in advance!

did you try to flash stock firmware? or just repaired it using pc companion?

Nop ( and basicly I have no clue what's that flash stock .. I just repaied it using pc companion ) ..
I think it has to do with the provider or something judging from what I read to similar posts
Just If anyone could confirm it would be good

Try to read about flashing using flashtool.it will be a great help to you. Also maybe it can resolve your problem.

Really need help!

Hi everybody. My Note 3 are with Telus. This morning, I've seen that the 4.4 update was online. So I downloaded the update for Telus from Sammobile and flash with Odin. But now, I don't have any network. Its write that I can only make emergency call.
I have try to remove my sim card and restart the phone, but that dosen't do anything. I really need help.
Thanks

Check your APN settings and also verify that you downloaded the correct software.
Worst case is Re-download and try again.

[Q]No mobile data access/internet access!!

Hi, I have this this problem no internet access through mobile network for several months now. After the official update 4.3 was release(around Jan,Feb) I install the update to my phone and then the symbol for data access(H+,H,R,etc) at signal bar never came out, I can still call and receive sms though. Then I revert back to 4.1 stock rom, the mobile data is there again! I stick with outdated stock ROM for several month and finally I decided to use custom ROM.
My phone is rooted with locked bootloader, I use CM11 rom and did every step correctly and the mobile data is gone on me again! So my phone currently can connect with internet with wifi right now, does anyone know what is the problem and how to fix it?
btw another problem is I'cant find my sdcard on my computer when I connect the phone to computer. No option on usb storage?
p/s: hate to revert back to stock 4.1, although I'm greatly fond with the illumination bar:crying: Now i'm in love with cm11, just tell me how to fix the mobile data access and I'm good to go

Mobile data is lost during flashing of a rom. There is no way of running away from that. But to fix mobile data, it depends on your carrier. Mobile data services are connected to the Internet antennas nearest to your device but it isnt possible to connect to them without an APN. An APN directs/connects ur device to the proper Internet provider and plan. This apns are lost usually during flashing. Most data carriers pre install a sim card application to your sim card after a couple of minutes(or hours) to your device usually with the name of your carrier. This applications usually have an option to set apns. Run that and follow their instructions and youll regain APN. But if ur phone doesnt have the app, go online and search on how to restore ur APN for your carrier.

care to show me the link on how to that?

You can also add the apn yourself
Settings > Mobile data and wireless > More > Mobile network > Accespoints..
And add them yourself Not hard..
You only have to apply the baseband fix when baseband is unknown under settings > about phone..

[Q] 4g problem i9305

Can somebody help me with this 4g problem?
This is what i did:
1.flashed custom ROM (worked like a charm,i did nandroid backup)
2.flashed other custom ROM (didnt like it so I restored the first one from nandroid)
3.everything went well except no imei and no baseband
4.reverted back to stock rom with odin
5.and here is the problem,no 4g signal at all. 3g/2g works fine.
If I post my build.prop can somebody tell me whats wrong?
I have tried to put my sim card in other phone and it works but not in my phone.

Did you enable 4G in Settings?
Sent from my GT-I9305 using XDA Free mobile app

Yes, I did...network mode is set to LTE
Is there a test that I can use to test is it a software or hardware issue?

Maybe an issue of Stock rom you flashed using odin.. Which one exactly have yoi flashed? What modem you have now? And finally, is your S3 i9305 or some i9305T variant?

Check this out:
Typ *#*#4636#*#* and goto Netinformation, then you will find a special-setup for the 2G 3G & 4G.
Sorry about my english. Cause i am german.
Sent from my GT-I9305 using xda premium

Thanks for your replies,I flashed stock german 4.4.4 from sammobile.It worked very good about 2 months.
I think that modem is xxufoa1 and version of phone is i9305 lte international.
If somebody could help me with this issue,I would appreciate that.But no hurries,I got new playmate S6 edge...

try doing a complete wipe of data and cache, then flash stock rom again to see if problem persists

I have tried many times but no help...

Hey, try flashing the parambin.zip file (look for it on google related to s3 lte, you'll find it easily). Another thing to try is just wait with the phone turned on with a valid SIM. I found out that sometimes it delayed a lot to get signal, specially when changing SIM carriers on another country. After a while waiting it finally succeeded (probably unrelated but I also saw on the catlog entries about upgrading the sahara file of the qualcomm chip -the modem-).
