I have problem with flashing, bought sgs2 today, wanted to make flash custom rom, phone is rooted with Doomlord exploit and there is cf root kernel flashed for cwm access (flashed via odin mobile), no simlock
When I flash any custom rom, phone apk keeps crashing, there is no cellular network and no IMEI in About the Phone section. I have tried restoring IMEI with EFS pro but after reboot its the same problem. I have EFS backup and nandroid backup.
What is wrong, I have two other phones, sgs2 and note, I didn't have those problems before, what is wrong this time? Any help will be great for me, I would appreciate ideas.
Is your phone plugged in to the wall charger or a USB port.
I used a custom ROM that would not allow me to reboot plugged in. Same problems as you.
When I reboot unplugged, service returns.

I'm aware of this problem, happend to me before, but unplugging doesn't help in that case. When I delete nv_data.bin and nv_data.bin.md5 it helps instantly but returns after reboot.
I have nv_data.bak in this folder and its some old file, like 2010 old, should I deleted it or something?
solved with wipe, which gave me random IMEI then restored right one with EFS Pro (thanks a lot for Dev Team of that app)
I keep reading about people loosing their ime after a flash but never bothered to remember if the flash was via CWM or Odin.
This might already have been investigated and I've missed it but it would be nice to know if anyone has lost their ime using Odin or if it's only through CWM.
This looks like it's happening more and more so it would be good to find out the cause.

This happened me yesterday, glad you managed to fix it, I didn't have a backup but thankfully there is a market app called GSII-repair and it can restore imei without a backup, hope this helps someone

Hey all.
I was on MIUI 1.9.2 and flashed VillainRom (wiped everything as usual) and after the reboot, I couldn't get any signal. Went to the mobile network screen and I get an error saying I don't have a sim card in my phone.
My baseband and IMEI all read unknown.
Tried restoring a nandroid with no luck.
Are there any fixes or do I need to send it off to be fixed?

Another problem with Custom Rom!
Anyway, do a Factory Reset, if it doesn't work then flash Stock ROM.

This might be a long shot but try toggling airplane mode on, reboot the phone and once fully booted toggle airplane mode off.
This issue has nothing to do with the Rom you flashed, (not VillainRom anyway) it seems in all your flashing you may have messed up your EFS partition, some people got it back when they flashed a stock ROM, if you don't, you may need to get in contact with Odia, he can assist you with getting your IMEI back

Good for you it worked .
Hi. I just Odin'ed back to stock firmware after experiencing no 4G data, only Edge, after flashing the Tmobile recovery through Rom Manager while on CM9 nightly #2. I had wiped and reflashed CM9, with no luck. I thought Odin'ing would fix the problem but it did not. I also tried removing the SIM card for a couple of minutes. Anyone have any suggestions what i could try? Thanks
Update: So far flashing CWM recovery using Rom Manager has set the IMEI to 0, on mine and MacTheRipperr's phone.
Anyone else with similar issues after flashing recovery through Rom Mananger?

Are you sure it wasn't a Tmobile problem? Maybe you should try other kernels and/or roms... I'm using AOKP on my Galaxy S since february and on my Galaxy SIII since June 19th, I haven't experienced any problems with mobile data, the link is below.
I hope it works.

Check your imei under the phone status. Do you have a 0? If so the same thing happened to me.
Do you have a back up of your /efs from the root?

Thank you for your response. I'm 99% sure it's not a Tmobile problem. I didn't have any issues with mobile data at all. This happend soon after i rebooted after flashing the tmobile Rom Manager custom recovery. First thing it did was give no signal connection at all. Then i reflashed the CM9 rom, which then was only able to get Edge network. Even after Odin'ing do i still only get Edge. I haven't tried a custom kernel yet. With certain devices, I've known of issues with modem's are sometimes fixed by flashing a standalone modem rather than going through the whole Odin process. But that isn't an option that is available for the T999 varient.

Yes it reads 0 and no i do not have an /efs backup. The root process I used was the Sprint root zip file flashing CWM and root using Odin. I wasn't aware of a backup that was made. After Odin'ing back to stock, i did the same root method and have flashed Redrum Lean Stock Mod which im currently on. Where would i find the /efs if this method did make a backup of it?
Question for curiosity s sake did you flask the cwm touch recovery
You should backup your EFS folder before flashing any rom, if you'd lost your IMEI you will have problems with mobile data and/or phone service.
I've found two topics about it here, the first one has a link to recover Tmobile and the second is more general. I hope it works!

You guys are freaking me out about losing IMEI. Thankfully mine is fine after rooted and flashing several ROMs.
How do I backup my EFS folder?
/sigh re-read all the imei threads, there's like 10 of them. Backing up the efs folder will not help you at all. The nv data.bin file is not there anymore and nobody has found it yet. Your only option is odin back to stock, take your phone back to where you bought it, and say this POS broke and i can't get lte even though i paid for it. If you're still under warranty hopefully they will replace it.
I'm stuck with the generic IMEI (004999010640000). I've tried a number of the various workarounds (GSII_Repair, manually deleting the /efs folder, flashing stock and trying both of those from stock, re-flashing CM10 and trying from CM10 again...) with no luck. I was actually missing files in my /efs folder before flashing stock, but even with the full /efs folder I can't find my actual IMEI. So am I screwed?

Honestly? Probably stupidity. I didn't even realize it was an issue until I noticed apps were confusing me for other users (apparently some apps identify you by IMEI). I may just see about getting a warranty replacement. It's been acting a little flaky lately anyway (a couple apps have randomly completely lost their settings). The tinkerer in me (the one that probably got me in this mess in the first place, although I'm not sure when it happened) wants to try and fix it anyway.

I guess my question is what should I be doing related to the IMEI? I've flashed to stock with Heimdall, but I don't have a backup of my original EFS partition that I could flash on there or anything. I thought maybe you were saying ODIN had some way to poke at something Heimdall didn't.

Are you sure you don't have an efs backup on your sd card? Some roms automatically back it up without you knowing.

Yep (I'm sure I don't have one). My /sdcard space was wiped on more than one occasion, back when CWM 6 decided to wipe it for me when it first started showing up in the nightlies. I ran a backup, and *poof*, there goes my /sdcard files. I tried recovering the files from the space, and was successful in recovering most of the pictures, but any large binary files (videos, archives, etc.) were corrupt. That said, I don't think there were any efs backups on there anyway, and I was having this issue before the space was wiped, I just didn't know the IMEI was the problem.

Yeah, I tried going back to stock. I did see one (XDA?) thread somewhere that mentioned flashing over and over out of frustration magically worked for someone. Maybe I need to do that.
Does anyone here know anything about the " echo 'AT+EGMR=1,7,"your imei 1"' >/dev/pttycmd1 " command? I came across this, but it is all on international forums about international devices.
Edit: I don't see a pttycmd1 in our /dev so I'm guessing it'd just error out. Is there a similar command for the i777?

I hope you didn`t mess up your EFS folder, did you back it up? If the EFS folder is corrupted/wiped and you cannot restore it you need to take the device in for repair.
Do you have the correct APN settings in settings, mobile networks?

I haven`t done it yet myself, so i`am not 100% sure on how to do it. Don`t want to get you into trouble by saying the wrong thing though,. There is an option in the S3 Toolkit to restore a efs folder i think. Download the S3 Toolkit by Mskip and read it well and try it or wait for someone else who knows more about this stuff. There are also various tools like for instance K-Tool by hellcat that can backup/restore efs folders. Good luck
get the philz touch cwm recovery
get into recovery mode
go into advance, restore efs backup
done
I just flashed the latest stable 10.1.3 from CyanogenMod (released September 23) and now my IMEI is blank. Is there any way for me to restore it? I stupidly do not have a backup of the efs folder. When I check the efs folder now, it's empty. Is there anything I can do? Any help is appreciated.
Try this.maybe it could help.
Take out your provider card.Boot the Rom without it.then turn it off and put the provider card in. Boot your rom now.Is your imei back?

I tried this on mine when my IMEI number was changed by a rom. It didn't work for that. I reflashed to stock and mine came back. Can't get a back-up because it won't stay rooted same reason I can't restore it with Titanium. I started a thread on that issue.
I don't think titanium does imei... Reboot to stock or restoring an efs folder backup are the only ways I know how to restore an imei

I used SOC, got root to stick, was able to load RemICS without IMEI changing. Thanks clicked.
Thanks for the suggestions everyone. I was at work when it happened, so I kind of panicked, lol. When I got home I flashed the stock image with Odin and now it's working fine. But I have since made a backup of the efs folder so I can just restore the folder if it ever happens again. You always learn the hard way, lol.
