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] No Signal/Network after Flashing a new rom

Hi guys,
So I had this problem before, but the Captivate magically fixed itself. This time... not so much. Or not yet anyway.
Upon boot I get a "No network" symbol. Sometimes it shows the bars on boot, but quickly reverts to the no network status. I just flashed the newest version of Cognition with the accompanying kernal. I have bounced around through various roms and kernals all night, but the problem seems to carry over (even after wiping the data/cache/return to blah blah).
Any ideas?

Try some other modem......

Crispy1805,
Try going to Access Point Names and tap menu then Reset to default. Once it populates at the top of ur screen, tap the dot, it will turn green and u should be good to go.
Menu/ Settings/ Wireless and network/ Mobile networks/ Access point names/ then menu/ "Reset to default" then tap the dot selector. Reboot should not be needed.

Apn are for data right, is this anyway related to connectivity to the network.

Yes, you need to be accessing at&t's access point to connect to it's network...

Hm, tried that, no avail. The problem is that it is not detecting any "bars" at all. I removed the sim, same problem. My Infuse is showing bars in the same location, so its not a network problem.

Did you make a backup of your efs folder you can restore?

Good point, let me check and try that if I can find it.

gah, I cant find it.

Try this http://forum.xda-developers.com/showthread.php?p=15158920 ... Use the 3 file version. It is kf1 stock, but the kf1 came with a seperate CSC .tar file and the kf1 is a full wipe... Worth a shot. But u need to already have the i897 bootloaders.
If this works, then u can move on to kh3 or whatever u r wanting to go to...

I flashed back to stock (enclair---odin 1 click and master clear), but it is still not showing any network /bars. I tried this --
http://forum.xda-developers.com/showthread.php?t=881162
but all of the values were already correct. When I check for an IMEI it says "not registered on the network" --- but it can't SEE the network as far as I can tell, so that makes sense. Perhaps the network card isn't coming on at boot?
Any more ideas?

This had happened to me recently, Some how 1 of my captivate lost the original imei and had the generic one 0000461090000, When u chek under the status it shows the details but no connectivity. I restored the imei and all ok.

Mine has its generic IMEI. It was sim locked for some reason, but I fixed that--- still no signal , just the blue circle with the bar through it. Under status:
Network -- Unknown
Signal Strength -- 0 dBm 0 asu
Mobile network type -- GRPS
Service State -- Out of Service
Roaming -- Not Roaming
Mobile network state -- Disconnected
Again, the Infuse right beside it is picking up signal (2 bars of "4G" i.e. 3.5G)

Update: Flashed to 2.3
Now the signal strength -- -111dBm 1asu
The rest is still the same :-\

Generic imei does not works in India we cannot register without a proper imei but it works in US members here have confirmed this. Check your lock status with *#7465625# what it says.

Just out of curiosity...If I make a backup of my efs folder now while running the FASTY II (KH3 i897 ROM) then flash say, Rom EPIC (JVS I9000 ROM) and end up having no network (This actually happened) will I be able to successfully restore the efs folder without having any problems?

Yes you can restore it.

Do you think its an EFS folder problem? I am clueless at this point.

Code:
You have a generic imei and it is quite possible the problem is coz of that.

No, I do not have a generic IMEI.

[Q] Data network not available? help would be much appreciated

Can someone help me.. i was resetting my wife's i9000 Galaxy S as it was running slow. And since its booted up i doesn't pick up the network anymore.. and when trying to call out it says "data network not availible".... driving me insane!

Check Here to chose your forum/Guide by Version of your phone or you will have more problems by using wrong solutions due to different versions of Galaxy S
try menu>setting>wireless and Networks> Mobile networks, to select your network

Ok, since posting i have managed to Update the fiirmware to 2.3.3 gingerbread using odin. But am still unable to use it on o2/Tesco mobile or even on Tmobile now! Emergency calls only, and gives the error (mobile network not available). I might be wrong, but i suspect something like the firmware for the modem or something?..

in Phone app dial *#06# and see if your imei is intact .. if it's gone then you have to flash a GB rom, root it again and return to CM10 . Use this guide if your imei is gone : [Guide]Upgrade SGS I9000 to 2.3.6 (Value Pack) & Root It

Ok I think I've worked out where the problem lies. Think it is a bad efs/imei as its displaying wrong after entering *#06# etc.. "004999010630000" grrr. So now need to work out how to get this back

[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.
Sent from my C6603 using xda app-developers app

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.

[Q] I9305 stuck with EDGE and no 3G/LTE

Long time lurker, first time poster.
Long story short, a friend gave me an I9305, however, I can't connect to a supported 3G network.
He had toyed around with the device (rooted, installed CM11), then reverted unrooted and reverted to stock firmware. When I got the device, I rooted it with Framaroot, flashed CWM 6.0.4.5, then flashed CM11 and Boeffla kernel. My SIM card was quite old and my carrier told that it doesn't support 3G, so I filed up for a new one. Ok, I got it, however..I'm yet again stuck on EDGE!!!
Tried reflashing CM11, CWM, flashed almost every radio baseband modem from here http://forum.xda-developers.com/showthread.php?t=2010116 to no avail. My IMEI is intact, as well as my Serial Number.
Yes, I read all threads, I tried going to Settings>Wireless&networks> More > Mobile Netwroks >Preffered Network type and checked all options. When I select 3G only, the icon goes to "H", but i can't access the web. After 10-20 seconds, the H icon dissappears and I'm forced to reboot the phone to regain my EDGE data.
At the moment, I'm running the latest Omni ROM nightly. My operator supports all 3G and LTE bands, and I got the correct APNs.
Should I flash a stock ROM and check if this does the job?
I'll greatly appreciate any help, because I'm stuck.

Wipe phone factory reset flash stock rom with modem and csc for your network.

I can't check my csc code - whenever i type a code in the dialer I get "connection timed out or invalid mmi code". The only ones that work are *#06# and *#*#4636#*#*...

Ok, so I'm running a stock 4.3 rom and STILL have no 3G....tried everything.
Anyone, help?

Maybe if you can try to downgrade to a firmware 4.1.2 via Mobile Odin and then try and access the service mode menu. From there you may be able to enable the 3G/LTE DRX (Radio) which seems to remain a permanent change in the phone once you upgrade again to 4.3.
