Help!! Error while searching for network - Cant use phone and need ideas

So yesterday night I suddenly lost service on my G1. Did all basic troubleshooting including call tmobile and had them reset their end. Toggling 3g/2g, airplane mode - nothing worked.
If I try to search for networks it says "Error while searching for network"
If I click search automatically it says "Your sim card does not allow connection to this network"
I need some ideas and fast. I cant make any calls.
I already attempted reflashing. I upgraded to cyanogen mod 5.xx, amon_ra, danger spl, and confirmed the correct radio.
I cant think of anything - please help

dial *#*#4636#*#* and go to phone information
wcdma prefered
turn on radio button

I had that happen .. it was a toasted SIM card.

Thread moved to Q&A.

i had that open too, try testing the sim card in another phone and see if it works or not. If you call the service number to ask for it to be replaced they might credit you on your next bill, a new sim card is about $22USD and don't overclock it next time

[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?

cannot connect to network operator

i have used MSM 7227_SEMC unlock tool, everything was looking good and the ROM was succesfully installed with NAA kernel then i have insert my SIM card and now i cant connect to my network operator? Phone finds all network operators in my country but it tells me "unable to connect to this network at this time".
the phone was unbranded.
pls help

try other roms bro

Your problem here is that, you got the phone network unlocked with a certificate change, instead of an unlock code...you might want to go back to stock

Try choosing select automatically with your sim inserted. I have to do this and cant manually select or I get the same message as you. Hope all goes well.

[Q] No mobile signal after CM9 + modem, but can see networks

I flashed the latest CM9 nightly two days ago, and everything seems to work great other than that I have no mobile signal. I am an Australian Optus user, and I tried it both with the modem that came with CM9 and with the one I believe is for my country, which is XXJQ3 by flashing that.
In both situations, I can scan for networks and see all three carriers just fine, but it shows no signal, just an "x" in the middle of the signal triangle, nor does it show which carrier it is connected to. I cannot make emergency calls because it says no mobile network is available.
Is this a modem baseband/firmware problem ? I am guessing not, because I would think that if it can physically see the networks, then the modem must be working right ? But if so, why can it not connect to anything ? The modem firmware I am using is for ICS and I believe it is the correcto one for my region, and I have enabled everything in the modem settings but still it will not connect to any network. Why ?

did you have try replace/update the modem radios from this? http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_Tab_(GSM):_Support_Downloads
you can try a different modem, It doesn’t matter if you prefer another modem, you can flash another modem, you can try flash any modem file you want, it's will not brick your tab
If you had, but still not working, then go to dialer, put this code *#*#4636#*#*, pick tablet information, try turn of the radio then turn on again and try to fix permission on cwm too.
good luck.

Thanks. Tried all your suggestions. Yes, that is where I obtained my XXJQ3 modem, which I flashed via CWM. I tried your other tip of turning the radio off and on again and then fixing permissions in CWM but to no avail. Still no mobile signal.
Is it correct to assume that if the device can scan for networks and see networks, then the modem is working ? The information screen you directed me to says "emergency calls only", but I cannot actually make an emergency call because it says "mobile network not available", so even though it can "see" three networks, it cannot connect to any of them to either get a signal or make emergency calls.
What does this mean ? Surely it has the right frequencies set otherwise it wouldn't see the networks at all, right ? Is this a CM9 bug in the nightly I flashed or something ? Wondering where to look. I get the feeling the modem is working fine and that something else is wrong.

I use the jlv modem from the vibrant phone.
But jpz modem is also OK for optus.
Why not do Android backup for safe keep, then restock using gb stock safe from overcome guide, and flash jpz modem to try.
If it is the same, then it is hardware related.

Oh my god. The reason it didn't work work is so stupid I had to headdesk when I realised. The SIM I was using was old and had been disabled. The reason I didn't think it mattered, is that in Gingerbread, it would still register and show reception bars and I could make emergency calls with the old SIM, or indeed even without a SIM in the device at all. But in ICS, none of that was the case, and it would not register and not let me make emergency calls without a valid SIM.
I guess I was just making a stupid assumption that SIM-less emergency calls that worked in GB would also work in ICS. Stupid me.

Everyone can make mistakes or forget something, but you should thank all the users who give you answers.

[Q] Network unavailable

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.
