Help! Lost network after installing MIUI RC3
I have seen in other threads that other people have experienced the same or similar issues and that it is possible that the IMEI number has changed.
The advice on other threads has been to flash back using EZBase - what should I be flashing back to?
Thanks in advance.

Well.. Double check your imei # first
Go to Settings>About Phone>Status
Scroll down a bit and write down your imei.
Power off the phone, pull the battery and check if your imei matches the number on the label.
Plus what CSC is in that rom does it cover your network did you try entering the network details manually .
jje
IMEI numbers are the same so seems fine, it did pick up signal for about 5 seconds but then stopped - it is T-mobile - UK.
I tried going in to enter it manually but it either comes up with an error or just says searching for ages - am I doing the right thing??

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?
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

Hi guys, I am officially screwed.
I had stock rom (unrooted) on my Note till yesterday. Suddenly it was just showing the GT N7000 screen and wont go forward even upon restart. Even the Samsung logo wouldn't appear on restart. So I went into recovery mode, installed PhilZ-cwm6 - Safe Stock Based Kernel from SD card, and wiped data, cache and dalvik cache and restarted without any problem. (Ofcourse all my data was gone but no problem)
After restart the Network signal was good, Data was working (could send and receive whatsapp etc.) ,however when tried to make a call it displayed "Not registered on network error".
On pressing the power button the screen turns off but does not get locked, main page is shown as it on pressing the home key.
There is no power menu too. The device would just turn off completely on pressing power button to access the power menu (Menu with restart and other options).
I flashed with custom Paranoidandroid rom but it displayed no network signal, so I tried flashing stock rom again with ODIN but the above problems still persist. Also, strangely there was no setup screen on starting the phone (which has always come on flashing a rom).
Read some where about keystr file being missing. Checked the /efs/imei/keystr it all there with text as ON in it.
Please help. I have messed up this phone many a times but was always able to recover it thansk to xda threads. I am even taking a leave from office for today.
Check your IMEI. Does it start with 0049...? The symptoms you wrote are typical for a developer IMEI.

Depends...
Your IMEI isn't the original anymore (remove battery and you'll find a sticker with your original one). This happens sometimes - I never saw an explanation why and when - when you install a Custom Rom.
If you didn't backup your /efs-partition you can't get it back by yourself. There is a member who offers a solution (he connects remotely to your device/PC and restores the old number) for small money (see cvxcvx.pl).
Workarounds:
- Change your SIM Pin every time after a reboot (you can simply use your old pin as new pin again, this works). Then you'll have a working SIM and network connection.
- On a TW based ROM you'll have to use an android.policy.jar from a leaked ROM (XXLSC). I used this because it doesn't check the IMEI and so you do not have the restrictions like you wrote: no SIM Pin request, no menu, immediate Power shutdown. I used this with my Pristine Roms because I have this developer IMEI since a repair in Thailand...
- Switch back to GB, it doesn't have the IMEI check too.
My actual workaround: disabled SIM Pin and using my own build "Pristine CM10.1".

Thanks, I guess I'll just need to take it to service centre. Could you please tell me how to go back to Stock ROM and Kernel so that there are no counters or root that may make Samsung ppl not repair the phone.
I was able to get back Lock screen and Power menu using instructions to recover imei here:
http://forum.xda-developers.com/showthread.php?t=1264021
with little modifications to it as I could not find original file.
However, my IMEI is still the fake one and still can't register to network.
Also the set up screen appeared on doing the above procedure.
Changing SIM Pin isn't helping in registering to network.
Hi XDA,
I have a Galaxy GT-P1000
My locality is New Zealand
Currently flashed;
2.3.6 stock firmware
Baseband JPZ modem
I recently messed up and didn't save efs while flashing and ended up with 0049. I paid a guy to fix it for me and IMEI is showing up correctly now. Serial # is still 000's.
My issue is;
With a correct brand new sim (and others tried) While signal is showing, I have no network, Under Settings -> About Device -> Status;
Phone Number : Unknown
Network : Unknown
Signal strength : (good)
Mob Network Type : HSDPA
Service State : Out of service
Roaming : Not Roaming
Mobile Network State : Disconnected
IMEI : (correct)
Serial number : 000's
I cannot make any phone calls, even toll free or to network support. 5 days ago this tablet was working on a network before flashing it.
Any help would be greatly appreciated. Thank you
You could try re-flashing the tab. There is a threads on re-stocking gsm tabs back to stock. If that doesn't work you could try manually programming the tab via the memo app. Open memo > in the search box type **772, that should open the programming menu. Thats as much as i know. You have to take it from here.

Ok a friend of mine brought me a i9305 lte to unlock as i have done several of my firends. so i did these steps
1. made a back up from QPST
2. Cf auto rooted
3. installed custom recovery
4. downgraded to 4.1.1
5. did the network unlock from service menu
i then put my sim card in but kept getting not registered on network. i tried setting service provider to auto and also selecting manually and it does the same but no longer asks for sim unlock code so i assume its now unlocked and has some other problem. i thought it may be a imei issue and checked but the imei is fully there and matches the one behind phone batter it also has the correct baseband.. i checked in the about phone menu and it says network unknown and out of service. thinking it may be a radio issue i proceeded to install a stock 4.3 that was originally on the phone from the network carrier it was originally locked to, to see if it was a radio problem but again get network unknown. so i restored the QPST backup over the stock 4.3 and it still says network unknown.
I am starting to think the phone may be blocked but not sure as i also hear its a common problem to lose imei and / or service during rooting. Am i missing something pbvious or fighting a losing battle lol..
one other thing of slight note is when i went to sammobile for the stock rom, when i was searching i searched for i9305 as thats whats on the sticker but it has a little badge on the back that says LTE which according to sammobile is the i9305N and i9350T.
thanks for taking the time to read this and the help you guys allways offer :good::good::good:
