i have flashed ICS RC1 there is no service not even showing baseband and IMEI...plss help me
Restore efs worked for me. If you dont have efs backup you fail.
Then go to stock rom with rooted kernel and use nitrality for backup efs. Then on rc1 restore efs and signal should work and imei should be back.

Once back on functionnal rooted stock ROM, disable SIM lock before flashing ICS. For me it resolve the issue.

this is not for development sry bro question and answer section
sorry
Were you able to backup your efs partition?
If you were able to backup your efs before the unlock, you may push the files back to your tab and check if that would restore the missing imei.
Or you could reflash your tab with a stock rom and see if that would restore the missing details.
On my Tab it is on the backside below the barcode...

Missing baseband means no modem. Flash one through odin.
Good day to all expert
I upgrade my sgs i9000 from darkys 2.3.3 to miui 2.3.4, i noticed IMEI changes from original 053xxxxxxxx to 0409xxxxxxxx so i decided to flash back to darkys 2.3.3 and IMEI returned to its original configuration. Is there any way to fix this issue or I did a wrong procedure in flashing rom.
Please advice
Thanks in advance
could try backing up your EFS folder to your SD card before upgrading and then restoring the back up once your on miui?
what happend when your IMEI number changed?
Try this to backup your EFS before flashing:

I upgraded from icssgs 3 to 4.2 abd ever since i get no reception at all. No data, no calls no nothing. Wifi works though.
I have tried since and flashing several different roms and the problem persists. Has anyone had this problem before or does anyone have a possible solution?

Have you tried factory reset, cache wipe, advanced and dalvik cache wipe, and then re-flashing rom? Are you using teamhacksung build 16?
risking to sound stupid, by " No data, no calls no nothing" you mean "no signal"?
if you've tried the solution suggested by am2012, have you tried installing a different modem?
try flashing a modem...u can get one from here

I have tried wiping and reflashing. I have also tried flashing different roms with different modems.
I reflashed the last rom that worked but the problem persisted.
I have had thoughts of flashing a rom with odin instead of cwm but i dont know if it should make a difference?
Thanx for the replys btw, all help is very appreciated.

Try wiping and resetting everything. Then put phone into download mode and odin a stock ROM. Then if things work start working again with your signal, flash rc4.2 again. I have flashed loads of ics roms and never had a problem I couldn't fix by going back to stock ROM. Try 2.3.6 the 'leaked one' from Sammobile.
By the way, you have got a i9000 international version haven't you?

Hey, just realised you have i9100. Have you used the right ROM for your phone? Does icssgs release for i9100?
Sent from my GT-i9000 using XDA App
Is ur imei at its place ???
If you've got an sII then icssgs is never going to work - go back to sII rom.
If you've got an sI then as sbnaul pointed out it is most probably your IMEI. Some users found their IMEI changed when upgrading to 4.2
Hopefully you've taken a backup of your efs - if so just copy the backup imei file over.
If not, there is still hope - flash stock gb 2.3 back onto the phone - this should restore the imei. Then take a backup of the efs folder, flash 4.2 and copy your backed up imei into efs
Thanks for the help.
I have 2 phones, one internarional sgs and an international s2.
I mostly use the s2 but i want the sgs to work nonetheless
Im gonna try reflashing the stock, i dont have any efs backups or such:/
I have been looking for a good stock rom but didnt find a good one. Im gonna look for the leaked sammobile release though so thanks for that.
How do i take the needed efs backup? Is it through cwm?
Thanks!

I'm quite sure that this is a modem issue...
If you know, which ROM were you using previous to ICS where the reception was fine, then you can flash that modem.
(For eg.: it was 2.3.6 XXJVU in my case. So, I would require a JVU modem)
Here is a concise list of all the modems: http://forum.xda-developers.com/showthread.php?t=1158783

Yes, I have tried that but it doesnt work.
But now I flashed the stock rom and I got the reception back. So now Im gonna root and try to backup the efs folder.
Thanks alot everybody to answered the thread.
There we go. Now it works again. I didnt even have to restore the efs folder.
I just flashed the stock rom, rooted and then flashed icssgs 4.2 and now it works.
Thanks everyone
full wipe , flash new rom worked for me
I've heard if you flash a stock ROM with Odin, then the problem with the IMEI (efs folder) is often done. Is this right?

Yup... that does the job...
Upgraded my SGS stock 2.3.3 yesterday to CM9 nightly posted on 07-06-2012. I love the ROM, but the only problem is - i don't have any network signal on my phone. Wifi works. It seems to scan the mobile networks and registers also and creates APN connections automatically. But on selecting any of the networks, it shows the message: "unable to connect to this network at this time. Please try again later." The IMEI number shows up correctly. Using Vodafone India network.
I feel it should be just a minor setting somewhere that is missing...
Does anyone know how to make this work?
...or should i switch back to the stock ROM, and maybe later to CM7? I'm on Linux. Found XXJVU ROM in Heimdall format. Do i need to install clockwork again after installing XXJVU?
Thanks in advance.
Wipe again.Flash again.
hey! make a copy from the zip file of the ROM and replace the file (apns-conf.xml) which is uploaded here as a zip file with the file (apns-conf.xml) in this directory "System/etc". it worked for me and i wish it will work for u bro.
send me if it work with u or not.
Why you don´t install de modem from the your ROM stock 2.3.3 ( via Odin ) ?
I think the new modem ICS is not compatible with the system of their country.
Tell me how you solved your problem.
Sorry, for my poor English.

Before upgrading I had taken the back up of EFS Pro application, after upgrading since EFS Pro was not detecting my mobile. I had installed root explorer on my mobile and copied the EFS data into /efs folder but it did not helped.
I used the latest ee rom from sammimobile to make a rom with android kitchen. Im a complete beginner to this and thought I had rooted, zip aligned and deodexed it. Signed it and it made a zip.
I flashed this zip and it got stuck at the boot logo. So i restored from cwm nandroid (which was of the same rom originally installed via mobile odin and rooted.) When it booted up I had no mobile signal.
I checked the imei and it had gone. I had backed up the nv data before hand but was unable to restore it due to connection issues.
I reflashed the same firmware(ee) via mobile odin and I had imei and signal again.
What is happening here? Can you back up a stock rom with cwm? Can I still flash other custom roms without fear of losing my imei. I like to try most new roms but im a bit worried about screwing up my phone.
Also does anyone know why my rom never worked. Like I say it was my first attempt
Thanks

Who knows what you have done wrong building a rom .
Can you back up a stock rom with cwm >>>>>YES but it will have rooted recovery .
Can I still flash other custom roms without fear of losing my imei>>> If you have EFS / NV backup.
jje
Why do you think I lost my imei? From the rom I made and if so why didn't the nandroid I made of stock rom with cwm restore my imei? It only came back from a fresh install of the same firmware?? Proper confused.
Sent from my GT-I9305 using Tapatalk 2
a nandroid backup doesn't touch the imei.
restoring the NV data is the only possible solution
I never restored nmy nv data tho and I got my imei back just by flashing stock rom again
Sent from my GT-I9305 using Tapatalk 2
right, I missed that part. don't know what caused it
Flashing back a stock rom is a known method of possible restore of failed EFS/NV .
But the word is possible rather than probable and not to be relied on .
jje
But now its back is it as it was before. As in free to flash roms as I please as long as they are legit I.E ripper rom and cm 10 roms etc?
Thanks

yes
Probably you don't put modem.bin in ROM package or put n a wrong place and updater-script cannot find it.
