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) .

Data connection/3G dropping after CM7+speedmod Flash

I posted in the forum and sent a PM to the dev but no one gave me any clues.
I flashed GB 2.3.4/CM7/SpeedmodKernel (comming from 2.2.1 Ultimate 8.2) following all the instructions as usual, after It booted up I was having issues with the 3G, so I tried about 10 different modems (including KC1 and JL2) and no-go. after I got to GB I found that the data connection was twitchy. The modem behaves intermittently, it switches to "H" with "no up/down arrows" (and it stays there, when normally it would only display "H" when TX/RX data. It gets stuck and get a connection error (browser/speed test/mail/etc) and switches to EDGE even though I've told it not to. I am running a 9000T version with 850MHz band 3G only. Whatever was changed in CM7 still follows me to every ROM I load.
I went back to my stock 2.1 i9000T FW via ODIN (with and without PIT) and same. Tried full factory restore, dalvik wipe, cache partition, factory reset, no-go. Tried my nanroid backup. Tried the magical JL2 and JK3 modems and same. Tried manually setting the 850 under *#BAND# (eclair/froyo), no go. Tried also the previous ROM that I had, 2.2.1, and switched to different modems and Still. I've noticed also that after a Modem change (lets say KC1), sometimes the baseband under "about" changes to another version (JK4 or something else). The modems that I've used have been re-packed to be used with CM7 and the ones for Froyo obviously for Froyo. APN settings are fine. Wi-Fi works.
I found these files under my /efs folder: cryptprop_applied_result, cryptprop_onetimeboot, and cryptprop_securewipedata, which weren't there before, I deleted them and restore my nv_data.bin ( I have a full /efs backup) and changed ownership just in case, no-go.
Somewhere in my SGS is still a file/s that has been modified by CM7 which I can't find, that is causing my 3G connection to fail.
Any ideas?

Anyone?

Odin should have removed any and all traces with a repartition with pit file only option I can therefore think of is wipe your sd card and flash a fresh rom again
This method worked for me a few times especially when I forget to disable lagfix

I have wiped the card about 6 times now. I have used either ODIN 1.7 and 1.8. I have also ticked the "Phone EFS clear" option, as I have copies of them, and restored the /efs, no go,
Last night I flashed GT_I9000_XWJVH_XXJVO_NEEJV3_Sbl (uploaded by Ramad), and it works great, with exception of the data issue. I even got my 3Button combo back (guessing that is the new BL).
I have even searched the /root directory and all the folders of the internal sd looking for unchanged files, nothing weird (for me).
thanks for your reply

Wow Jesus that leaves me stuck you say the apn setting is fine sounds dumb but the mobile data is active isn't it are you sure you apn settings are correct cuz I really am lost for words
Also you might wanna try EZBASE
All these ideas may get you nowhere but worth trying
I'll keep thinking I no what is like to have an issue you just can't get fixed
Sorry I'm not more helpful

check your apn settings, if they arent there phone your carrier up or go to their website and get the settings

Tried that, they were correct settings so i activated them (green dot) rebooted a cuple of times, still no signal

Ok, still a noob and kina frightened to mess around with wrong files with Odin, any chance of a link, UK Vodafone is my network carrier.

GSM Problem after flashing ROM

Dear friends,
I have a Samsung Galaxy Note. I tried flashing several custom ROMs. Then I figured out that my GSM modem loses signal every now and then and I have to restart the phone every couple of minutes. (Going to flight mode and returning back also works).
I thought it relates to Custom ROM, so I get back to the stock ROM, but didn't solve the problem. I tried flashing different modems using Odin, but all of them are losing signal... So currently I can't use my phone
I live in Iran and tried the following modems:
XXLA1
XXLA3
XXLA4 (My friend's Galaxy Note official ROM uses this as base band)
Maybe I have to get back everything (include partitioning) to factory defaults from the scratch... But how?
FYI: My SIM works well on other phones.
Please help... :crying:

Check your efs folder. Search the forums.

In my case, GALAXSIMUNLOCK didn't work :crying:
Also I used EFS Pro to recover NV data and still no hope... I don't have any backup from my EFS folder.
Any other opinion?
How can I restore everything to factory data including EFS and all partitions? Could it work at all?

no way to restore efs to factory defaults if you don't have a backup of that time.

I don't have any IMEI problem, nor a network lock. When there is signal, everything works fine just as usual. There's even no disconnection during calls. But when I leave the phone alone, it loses signal after 5-10 minutes (sometimes more) and I have to restart or enable and disable flight mode.
Maybe it is not related to efs or network lock at all...

[[Update]]
I figured out that the problem only occurs in my apartment's neighborhood and both SIM and GNote 7000 work well anywhere else. But the problem raised just after I changed the ROM.
Could there be something wrong with the nearby BTS and Galaxy Note? My SIM works well in an old Nokia phone in the same area!

normally it should be fine if you flash the modem/radio on your own region.
when you said you have flashed so many modem file, is it from other region, or is it from your own region ?
Previously when I got problem with the signal / network provider, I will just flash back the modem of my own region. Everything works well.

[Q] Can't connect to mobile network

Hello,
I've got a Galaxy Note, which a mate gave to me, because he has the new Note 2 now.
He said that he has some network problems (he has two times vodafone.cz), but didn't say anything in detail. So I thought the problem would be solved with flashing another rom, like CM 9.1. He already had the stock 4.0.4 and I read that I have to flash back to GB before flashing to CM 9.1.
At first I made a backup of the efs folder with kTool. After that I flashed the LC1 version of GB (3 parts, open Europe) but with this flashing process, I lost my IMEI ! So I wanted to restore the efs folder with kTool again, but it didn't work for me, I still had no IMEI.
I thought that the structure of the efs folder could have changed from 3.6 to 4.0.4 and that this would be the reason why I can't restore the efs folder. Therefore I flashed back to a Samsung stock rom of Android 4.0.4 (N7000XXLRG_N7000DBTLRG_DBT).
And then the surprise: I had my IMEI back, without restoring the efs folder!
This just was the background. Now to my problem: I still can't connect to the mobile network. In the notification bar is written "emergency calls only" (I don't know if it is translated on the right way, because I'm from germany). If I go to the network settings and search for mobile networks, I find all the networks I reach in my area, o2-de as well, which is my favourite network. But if I want to register to the network, it takes a while and then it says: Registration failed. And after that, I also can't make emergency calls, there is written "No service"
All in all my question is: Why am I able to find networks, but can't register to my one? I also tested it with other SIM-cards from other providers, but it still does not work..
I hope anyone of you has a solution for my issue.
greetings
Senfy
Edit: My IMEI begins with 359, so it should not be a developer IMEI

May be it has network lock. Have you tried apps like galaxy s unlock from the play store.

I tested it now, but everytime I want to unlock my phone, I loose my IMEI and I have to restore the efs folder..
But if I open Galaxsim Unlock, it says my device isn't locked.. so this seems to be not the solution..

Now I flashed to CM 9.1 with the hope to solve this problem.. CM 9.1 works, but I still can not register to my network... has anyone another idea how to solve this problem ??

Are you check an eyes in code or test menu ?
Go in dialer and tape
*#0011#
Then use menu and back in menu to come on general and check in different menu(debug)

I'm sorry I don't understand you. If I dial this code nothing happens. I also searched for this code (google) but without any result.
maybe you could post a link with an exact description how to do what you mean..
But thanks for your effort.

Now I wanted to flash another modem.. but everytime I want to flash it, I lose my IMEI !
The only way to get my IMEI back is to flash back to N7000XXLRG_N7000DBTLRG_DBT ...
I don't know what to do next.. I would be glad if someone could help me..
Edit: What I forgot to tell you: The reception of emergency calls goes up and down over the time.. maybe someone of you can conclude anything out of this information..

Doesn't anyone have an idea how to solve this problem?

how are you flashing the modem? tried mobile odin?

I flashed the whole GB (3 parts) with PC Odin and the actuall modem with mobile Odin but with no success..

Where is da solution 2 no network after update
