[Q] Network unavailable - Xperia Z Q&A, Help & Troubleshooting

Hi, Ive got xperia from vodafone australia.
When I first started my phone I upgraded it to 253 straight away. Everything was working fine, but needed root.
First I tried to open the bootloader following instructions from sony but something went wrong(bootloop) so I used the SUS for the recovery. Worked fine, and when the phone was starting for the first time it went through some network configuration.
Then I downgraded it to 434 with unbranded australian rom. Upgraded to 10.3.A.0.423, unlocked bootloader, rooted, everything was looking fine. But today in the morning I tried to use my phone and it says "network unavailable" when i try calling or that "the message couldnt be sent" when trying to text. I locked bootloader, flashed with sus, then flashed the same unbranded rom and still the same!
Emergency calls are working. Reception is full but it doesnt display "H"(wifi is off).
Is there any way to run the network configuration like it was after restoring though SUS? After flashing another roms there wasnt this kind of thing..
Anyone could help?

I flashed another rom, 10.3.A.0.432 from spain and my data connection started working(yes, im sure that wifi is off). But still I cant make a voice calll. During the basic configuration it asked me about my network and if I want to download internet settings. Is that possible that I need specific settings for Vodafone?
When I tried calling my number from another phone it just says "call ended" instead of connecting to the voicemail.
Anyone?

Try another SIM card.

I'tried another vodafone card, was the same. Tomorrow I will try to get card from another network but it's a bit doggy, that I got data connection but no voice calls/texts. Remember that long time ago on wm I similar problem but there I was helpful the reinstall radio and run connection settings. Is there anything like radio drivers for xperia?

on android the radio is the baseband, have you called your provider to see if there are any issues with them or your account?

What do you have in APN in your phone?
Check it in Settings => Wireless & Network => More...=> Mobile Networks => Access Point Names
If you have no APN don't search further, this is your problem, you need to fill the APN with your operator informations.
I've had exactly the same problem after réinstalling the phone with PC compagnion.

Network Error after 2.1 unbranded flashed

Hi all, well, here is my problem.
I have my stock rom 2.1 eclair from Personal, Argentina, and i flash the phone to put the 2.1 ARO (Unbranded). After the flash, the phone works great for a while, then i lost connection, and i coulnt connect to my network anymore. I couldnt performs calls, sms, or whatever related with communication. I only have wifi.
If i access to Mobile Networks -> Net Operators, the phone keeps searching and never retrieve the list of network operators. My apn list is empty, and i couldnt add new ones, mannually or by APN Restore & Backup software. The network mode is not selected, but if i choose one mode, it doesnt selected it.
I Flashed the phone with Odin, with and without repartition, but it still having errors.
Any one can help me?
Factory reset first .
jje
i've performed a factory reste, but nothing happends...
try to deactivate the mobile data and restarting the phone this worked once for me, if that doesnt work i would suggest trying another rom this also worked once for me. And if all else fails then your gonna have to send it back for repair, i had to do that last time this happened. I put on the 2.2 update from my carrier and told them that the phone messed up after updating.
The endless searching for a carrier is normal, but you should be able to enter apns manually. Search for the code to check IMEI and confirm you have one listed.
If you have a backup of your efs file, you can restore that and see if it solves the problem, or load an Argentinian csc file (they may have one in the ROM Kitchen that you can cook as an update.zip) .

[Q] Mobile network not available..?

Hello, I bought of a friend a Samsung galaxy s and he said it needs only unlocking,so i "think" i unlocked it successfully.Was putting a O2 Simcard in and in applications i was having then the o2 SIM Toolkit.
But when i tried to make an phonecall, he tells me "Mobile Network not available",so i went to settings and wireless and network and tried to choose an network operator but he tells me then " Unable to connect to this network at this time.Please try again later."
What can I do?
Did you check the APNs?
Please first check if your IMEI is intact. If it is, flash a different MODEM and see if it works. If it's not, flash a fresh ROM using ODIN and that should hopefully restore your efs.
At first thanks for the reply, but now what is a APN? And how do i know if my IMEI is intact?
Sry,am a newbie
For you IMEI you should check your original SGS Box's sticker. There should be you IMEI number printed on. If you dial *#06# you should be able to read your IMEI. --> Look if it is the same as on your box
for apn settings. Apn is your connection settings, how your phone connects with the providers network. you have to check your mobile network settings if these are correct.
So, the IMEI nr is different then on the sticker,and the apn wasnt ticked,so I ticked the O2 and tried but still no mobile network.
Then i need to flash if I'm right?
I was already looking a bit around here about roms etc. But there are quite a few out there,so when you say to flash a fresh rom,which actually do I need to use?
Thank you
Hi again,
because the imei wasn't the same, I flashed it with a new rom (actually two different ones)
But still after both flashes I still don't got my old imei and still no mobile network available. After the one flash with I9000XXJPU he didn't said anymore no mobile network available,instead he said no data network available.
It would be nice if somebody would have some advice or help.
Thanks
hey! don't panic, i have had the the same problem
just download darky's resurrection edition in the development section and flash it. it should bring you back to froyo 2.2.1 and should also restore your imei properly. after this procedure you are free to flash any rom you want

Flash back to 2.2.1
Check imei
Continue on..
Also the problem you had when flashed JPU sounds like you didnt have your APNs correct..thats why the "no data network available"

No Network
Hi!
I have the same problem.
Network is fine (i switched the SIM-Card into different phones), but my SGS GT I-9000 does not connect / find to any network.
I am running Darky`s ROM 4.0.4 v11.0 Black Edition with 3.0.17-Semaphore_ICS_1.2.5s.
Also, the phone says on screen the name of my network provider (COSMOTE), but no signal.
What now?

[Q] How to get mobile networks working on Milestone Cyanogenmod?

I just flashed kabaldans Cyanogenmod 7.1.4 coming from 7.1.1. Like I've done many times, changed baseband to "Venezuela - Mobilnet" in OR, updated google apps and everything.
But now my phone says "Emergency calls only", when I check the network operators option it only shows one of the three operators in my country, and the one that my phone is registered to does not show up. Ive tried reflashing the baseband 5 times but the result is the same, still can't connect to the network for calls, much less data.
EDIT: I flashed 7.1.1 and the network works just fine..
if you've tried setting Baseband, why don't you go ahead and file a bug at http :// code.google.com /p/cyanogenmod4milestone/issues (sorry, new user, can't post links...) so kabaldan/nadlabak can fix it?
I would definitely try reflashing to the newest and using openrecovery to flash the baseband onto it. I can't imagine that would have been a broken feature.

[Q] HTC One mobile network not connecting

Im currently running Android Revolution 41 ROM, 4.4 Kitkat with firmware 4.06.1540.3 drivers. Im unable to connect to my GSM cell network. Manual searching shows network but wont connect. The sim works perfectly in another phone. I cant figure out why this is happening. Please help.
Make sure your APN is entered exactly as it should. A single . or - out of place will get you no data.
Did it work on stock firmware? Blacklisted IMEI?
If you just flashed the rom maybe the APN got deleted. Happened to me when I flashed ARHD, just re enter your APN, if you don't know it a simple call to your carrier or even google will do fine.

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 ?

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?
