[Q] No LTE option ( C5303 ) - Xperia SP Q&A, Help & Troubleshooting

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.

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 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 let you know i send the mobile today on service center tomorrow they have it ... let see how long will this take and if the fix the problem or send me new one cannot say..
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] Problem with signal after choose usa radio band

hey guy's :
I need a solution here with my sony xperia SP, I bought it 3 weaks ago and I got this problem... when I have some problem with my signal in my place i just can get 3G and i try the method using *#*#4636#*#* and accidently I choose the radio band and set to US radio band.. and after that my phone can't get a signal I try to change the sim card but the problem still same, try to factory reset it's just same too.. anyone have the same problem ? or anyone can help give a solution with this problem to get my signal back ?
thx before...
Not sure what to say. Can you not re select the option from service menu.
If not then I think you may need to reflash phone either by sus pc companion or flash tools.
Just make sure you select right file for your phone ie c5302 or c5303, don't think there are any files posted on xda for c5306
Sent from my C5303 using xda premium
You can also flash only the kernel with an older version and let the phone make de OTA update to 254. After the update the problem should disappear without loosing data. It worked for me at least.
Just make a factory reset

i9305 no mobile signal..what else can i try ?

I Have had this i9305 now without mobile signal, with a vodaphone it did used to show signal but in all cases it always says 'no mobile networks' or 'not registered on network' i have tried with every sim i can think of... it was suggested to flash a stock rom which i did..this made no difference, i then tried installing CM11 and followed the guide to the letter.
I know this phone is not blacklisted as i checked with the imei, i have tried flashing different modems but to be honest im not sure what i am flashing to it..i have tried three different ones now starting with XX as i am in uk...i really dont know if i have missed something or doing something drastically wrong..i have read and read and usualy i would have had this resolved by now...can anyone please help me as i want to give this handset to my girlfriend for a present very soon so we can keep in touch..i am at my wits end with it:crying:
Thanks
Try an emergency restore through Samsung Kies - this should eliminate any software related problem. Sounds to be a hardware problem though so get Triangleaway going and send it for repair if that doesn't work.
Flash 4.1.2, then enable and disable the LTE-only mode hack in the hidden service menu (the *#2263# one, not *#*#4636#*#*). (If you have root, you can also access that menu in 4.3 or even the 4.4.2 port, but it's a bit more involved.)

it won't let me do that as it doesn't list the phone as needing an emergency recovery. I flashed a stock rom and the signal is showing but it keeps saying not registered on network.. if I do a search it finds providers but when I opt for the provider of the sim it just perpetually spins at registering on network.

when you say 4.1.2 which rom.. A stock one or a custom.. could you point me please ?.. The stock rom I have flashed is 4.1.3 I didn't flash a radio after as being stock it would be there already ??
Have just followed a guide to root this unit, upon installing root checker it says this device does not have proper root, Odin reports that everything went ok and i get the red pirate android..when the phone boots a pop up comes up saying unfortunatley SU has stopped working... not sure whether KNOX is stopping this ?
no network.
Hellow to you all.
I have got a problem in my s3 LTE.

please start your own thread as it is not relevant to mine.
Someone's suggested this phone is barred.. I have run a check which says it's not blocked but it's been suggested that this is unreliable...I have bars showing but just never registered on network.
Does your IMEI reported in *#06# match the one printed under the battery?

its really strange problem. go to service tests > security > see all 9 keys are there with Key OK Active written
And as u have restored TA partition and DRM keys, you can use Sony PC companion software to repair your phone
OR
use flashtool to flash the ftf file for your specific region
