Hello, my friend flashed his Optimus 3D (LG P920) and lost his IMEI.
I managed to recover it by flashing the phone THREAD
However I have a question - How can I backup the IMEI or prevent it from getting deleted when flashing custom ROMs?
I'm sorry if this has been posted before but I could find a thread specifically for this phone.
Thanks in advance.

Remove the battery and you will see your IMEI
Or if he still has the case, it's on a white sticker on the back.
I don't think you quite understood me.
After flashing a custom ROM the IMEI inside the phone memory gets deleted and there's no signal or anything.
The only way to fix it was to follow the guide in my initial post. I know that the IMEI is under the battery but there's no way to set it in the phone's settings other than flashing.

you do not LOOSE your IMEI, you OVERWRITE it. so... you have to overwrite it back to have you IMEI. For this you need a commands in the thread you already know.
A while back, I lost my IMEI flashing CM10. I restored that back, and got my phone working again, but every time I leave the local area code, my phone says that I am roaming. Being that I recently moved out of state, this means that my phone now says that I am roaming all the time. While this doesn't greatly affect anything, I would like to fix it. The problem seems to stem from my ERI (ERI version: none). Is there any way to repair this?
I too have this problem now. I recently flashed a few cm10 nightlys one after another using the built in updater and I lost my imei. After using the nv-item_reader_writer program and the nv generator I was able to restore my imei but am still without an erI
This is what I did to get my eri back after losing my imei and restoring it. There may be some steps you don't need to do but it worked for me.
1) I flashed a stock rooted TW rom.
2) Next I flashed the VRLF2 modem found here (Click spoiler to see them) : http://rootzwiki.com/topic/34053-firmware-vrbmf1-modemrpmtzsbl-verizon-sgs3-sch-i535/
3) Next, I got my eri back using the forbidden software in this thread(You're going to have to search the thread some but you're on the right page): http://rootzwiki.com/topic/32397-tu...ants/page__pid__1218913__st__220#entry1218913
4) Follow directions in OP of same thread.
5) Once you have you ERI back to 5 and your phone shows verizon network I highly recommend going to Synergy rom thread and looking for the HW keys back up zip. It can be found if you look through the attachments in that thread. Make a flashable copy of your keys with that zip and place on your sd card and in multiple other places for safe keeping.

Thank you for this. I do not need iut currently and I do have a proper NVBackup but you never know . I have it on my Box account just in case and besides I could always help someone that didnt do a proper NVbackup. Quick question. What happens if you flash a 16 GB PIT on a 32 GB Model? Would it brick you or just give you a 16 GB S3? I have a 16 GB model but just curious. I need to read up on this stuff.

Since I had restored my imei with qpst all I did was use the tool to restore my eri. From what I've read it won't work unless you downgrade your modem. I didn't have to mess with the PIT files listed. I don't think it would be good to mess with those without talking to someone who knows more than I do. JMO, I don't think it would end well mixing those up. I also forgot a step, once you're back up with your eri you can upgrade your modem back to whatever is best for you. A lessoned learned the hard way for me. I haven't had to worry about losing stuff like this since the original EVO 4G.
Hi all, I'm newly registered here, however, I have been coming here to XDA for over two years now as unregistered to browse and become more knowledgeable regarding rooting, unlocking and ROMing my phones. I would like to use the Casual Root/Unlock/Recovery AIO Toolkit and finally have more freedom over my locked down Verizon Galaxy S3. I am currently running MF1 and I'm completely 100 percent stock. I've downloaded Casual, have all the Samsung drivers installed and am anxious to pull the trigger. I just want to confirm I'm on the right page and do diligence first. After I run Casual and Root, unlock the bootloader and install TWRP, would it be wise to immediately boot into recovery and then backup the rooted MF1 firmware and then back up my imei by copying the efs folder to the SD card and my PC? Is this method correct for backing up the imei or is there a specific program for it? I have searched through many custom ROM's and I am planning on flashing Beanstown106's Jelly 'Beans' Build 19 ROM, as I love the fact it's AOSP themed but has a lot of features from Touchwiz. Does this ROM happen to back up the imei automatically by chance? I've already backed up my contacts and important information, so are there many things I'm missing or am I on the right track? Before flashing Jelly 'Beans', would I need to wipe the cache / davlik at all? Or is that only when coming from a different ROM? Any help wouwould be greatly appreciated and many thanks in advance for your time!

To backup your imei/eri check the synergy rom thread. They have a zip to back them up. It's in the attachments. It only takes a few seconds but will save you a world of headache. If you want my opinion that's the first thing you should do once you root, unlock and have your custom recovery. Store that zip on your SD card, PC and cloud(Dropbox, Copy, Box, Mediafire, etc).

Here you go : http://forum.xda-developers.com/attachment.php?attachmentid=1281376&d=1345868740
Once you get root and unlock the bootloader, backing up your EMEI is recommended (I did not until I flashed my first ROM). There is a great
thread that the previous poster may have pointed you too (if so, sorry for the repost): http://forum.xda-developers.com/showthread.php?t=1852255
Previously you were pointed to the Synergy method (B). But A is very easy too, requiring you to have a terminal emulation app on your phone (I have Rom Toolbox Pro, which has a terminal emulator). Type in the two commands as instructed and it reboots. I then did B and hopefully I am doubly covered.
After that, flash your preferred ROM (lots of really good ones, I use BoneStock 3.4) and you are ready to go.

I greatly appreciate your help and advice as well, it's nice to know of other possible options backing up the imei. Something else I just thought of, once I root, unlock and get recovery using Casual, should I expect to see a message from Verizon stating that the software running is not official and to visit one of their stores? I have seen others mentioning this, but I'm not sure if and why that pops up. If it does, does it continue to pop up or stay on the screen at all? Or is it something that you can dismiss and you don't see it again?
Do you guys know if terminal emulator comes already installed on the Jelly beans rom by chance? Because that seems the easiest way to do it just by typing in those two commands. However, I would still download that .zip tool from Synergy as backup. Or would that not be needed at all if I was to use terminal emulator?

After using casual, do I just place that zip on my sdcard pc and cloud and then run it if and only when the imei is lost? Or run it prior to placing it on the SD card and such? Sorry for all the newb questions.

After you finish casual place the zip on your external sd card. If you haven't flashed a custom rom with boot to recovery menu you'll have to get to your recovery the hard way. Power down phone, hold vol up and home button at the same time you press power. Keep holding home and vol up key and let power button go. Phone should boot to your custom recovery, either CWM or TRWP depending on what you choose to use. Next go to install and navigate to the Synergy zip and choose install just like flashing a rom, kernel,etc. It will place a Synergy folder on your external sd. That folder will contain the backup zip you'll need in case you lose your IMEI/ERI. Make at least a couple backups of that.
Awesome! I really appreciate the help and quick responses. So once I've done that, if my imei should become lost, I would open that synergy folder and use the backup to restore the imei?

If you should ever need to just flash the zip in the Synergy folder, hopefully you won't ever need to. Once I got mine restored I haven't had to yet...fingers crossed.
Ok, perfect. That really sums it all up for me. Yea, hopefully you won't ever need it.

Man i was right there with you. Not quite two years, but maybe two months of reading, researching, watching vids, etc. I downloaded the casual too because i am not great with adb commands, etc. I will tell you from personal experience exactly what my opinion is of what you should do. Someone else more experience may have a better way but now that i have become a serial flashaholic hindsight is always 20/20.
1. Find the stock firmware for the Verizon Samsung Galaxy S3 any version whether is be VRBMF1 or older and download Odin. That way if anything happens short of a hard brick you can ALWAYS Odin back to stock if you are completely out of options.
2. Run CASUAL to (a) Root (b) Unlock the Bootloader and (c) download TWRP ; I have used Clockword Mod and TWRP and I personally found TWRP much easier to use
3. First thing I would do is download the Synergy HWkeys backup zip and flash it while you are still stock rooted to backup the imei. Thank God i haven't lost the imei before i backed mine up but that way you have plan b and plan c, etc.
4. Make a TWRP Nandroid backup of your stock rom that way you can always restore back up stock.
After you do that you are good to flash away my brotha. And a note too, remember that for most roms you need to flash gapps separately. I freaked my first flash and thought i broke my phone because i had no google apps but that was noob stuff on my end.
I hope this helps but all these roms and everything are really cool. the reason i came to android in the first place. and i dont donate as much as i should but you gotta give it up to these developers. anyways. later man
happy flashing
Synergy backup works. I recently lost mine and had to restore it. It was super easy to do, but I wasn't sure at first if it was going to work. Couldn't tell you what caused it because I am super careful to download all the correct files to flash Roms. Also all AOSP Roms require you to download the GAPPS for whatever version of android it is running. All TW based Roms already have the GAPPS included in the ROM zip file. Just be careful when switching back and forth between AOSP and TW Roms. A good practice is to wipe everything 3 times to make sure you got everything. Sometimes also there are residual files and/or folders left over from AOSP Roms when switching back to TW so I have a practice of wiping internal storage before I switch back to TW. Just move whatever files you want to save to your external SD card. I switch Roms often so I usually don't have to move very much. I also don't restore apps or data from titanium backup. This most likely can cause problems if you're restoring data from a different ROM.

Hi,
After installing a custom ROM, the IMEI reported by Android is different from the one on the sticker under the battery.
I believe the IMEI is somewhere in the 'efs' folder, but where exactly? There are all sorts of files and folders in that folder.
There is even a folder called 'imei', but it contains just one file called 'mps-code.dat', and that is only three bytes long, which isn't enough to contain the 15-digit IMEI.
Can anyone help?
Thanks,
Steve

No, my phone stopped working and I think it's because the IMEI has got corrupted when I was messing with various custom ROMs - it no longer matches the sticker. I want to figure out a way to fix it - I can't bear the thought that I've just bricked a fine phone that I paid good money for.
Where in the efs folder? There are loads of files and folders in there.
Thanks,
Steve
Wait wait,
You can't text or connect to the network?
Try flashing a official firmware and see if the IMEI matches...
It's not that simple to modify your IMEI n.o, special softwares are required to do this.... It's stored in .nv_data
Don't you have any efs backups?
IMEI getting corrupt is seen many times in s3 and note 2 devices....
And also, modifying your iMEi is illegal, but people out there use a software to do it.... May not be good to discuss this software here...
And one more thing, does your phone shows a generic IMEI number when you dial *#06* ?

Not a generic one. It's really weird, because it's almost but not quite the same:
Sticker inside phone:
xxxxxx05861xxx3
*#06#:
xxxxxx05681xxx1
The ...86... has reversed to ...68... and the final 3 has become 1.
I'm an idiot and furious with myself.
Thanks again for any help you can give, though.

Wow! I've just seen how much it costs to buy that eight-tentacled device who's name shall not be mentioned.
$135 makes poor sense if it's only going to be used once. Perhaps the best idea is to check my local phone repairers until I find one who has the device?
Steve
Bumpety bump just this once:
Any chance of correcting the IMEI myself?
Thanks,

Can't find some content for your device but please do one last precaution before following any more tutorials, backup your efs folder and place it in a safe place.......
If you don't find anything, I can provide you with some guides for s3 (my device ) but don't know if they'll work for you....
One advice, reset your phone and send it to any service center.... They may charge you if you are out of warranty.....
here is a random thread i found but I have a bad feeling about the person.... Carry on at your own risk but back up your current efs, it may be recoverable but can move to a unrecoverable state after some repair attempts so, we can have hope....

Thank you again, eatsleep! I really appreciate your continuing help.
I've gone about as deeply into this as I think I can, without trying even more bits of dodgy software from around the web which might make the situation worse. So, I think my next step should be to take it to a reputable service centre on a no-fix-no-fee basis. If they can't fix it either, then I'll regard it as a write-off and - on the grounds that there is nothing to lose - I'll have one last go with anything/everything I can find on the net.
Whatever the outcome I will report back so that others can benefit from my mistakes!
Thanks everyone who tried so hard to help - have a good weekend.

Yeah, samsung can definitely help you, but again, be sure to make a backup of current efs to get back if situation gets worse!
And if you fail, then we can try some softwares out there, which might me improper to discuss here, but leave that for only when everything fails....

Restored her back up, and by mistake recovered her efs in my phone. Now imei shows 000000. As I said, my back up corrupted, cant open on pc, twrp shows errors of corupted file...how can i recover my imei? Flashing stock clean rom via odin or samsung swich doesnt help...

Time to send it back to Samsung for a new board. That's if they have one. Other then that you can try flashing a compete stock rom but normally that doesn't happen.
You learned a lesson. Never restore a backup from a different device.

Sooo, my gf and I have same phones. S7 edge. I made back up of mine superstock rom. And made back up of hers rom. We decided to change phones becouse I bought rose gold very cheap and she has gold. So, my back up i transfered to pc, which later got corrupt I dont know why. And her back up tranfered to my phone. Wiped everything. Restored her back up, and by mistake recovered her efs in my phone. Now imei shows 000000. As I said, my back up corrupted, cant open on pc, twrp shows errors of corupted file...how can i recover my imei? Flashing stock clean rom via odin or samsung swich doesnt help...

Without an IMEI/EFS backup that was created before doing this, you're not gonna find much of a solution for restoring the device.

Wait wait,
You can't text or connect to the network?
Try flashing a official firmware and see if the IMEI matches...
It's not that simple to modify your IMEI n.o, special softwares are required to do this.... It's stored in .nv_data
Don't you have any efs backups?
IMEI getting corrupt is seen many times in s3 and note 2 devices....
And also, modifying your iMEi is illegal, but people out there use a software to do it.... May not be good to discuss this software here...
And one more thing, does your phone shows a generic IMEI number when you dial *#06* ?

Hey everyone! I had flashed Lineage 14.1 on my Samsung J210F(https://forum.xda-developers.com/an...ageos-14-1-t3680656/post74433279#post74433279)
And everything was working perfectly until I wanted a file from the stock ROM. I flashed the stock ROM and after my work was done, I flashed Lineage again. Now in the middle of this flashing I lost my network. I tried changing the APN settings and even tried putting it on GSM Only but it's of no use. The network comes and goes abruptly. I even tried going back to the stock ROM but now it's the same over there too. My radio band and everything is as it is. I just can't figure out what's wrong. I have tried reflashing multiple times. There is no problem with the physical hardware or the sim as I have tried it with a different phone too. I haven't touched my efs file either.
Any suggestions would be appreciated!
Somebody please help. I just cant find any solution to this. I've been through each and every forum possible but I still cant find anything. IMEI and everything is normal. I did try to flash the stock rom and the stock rom receives network but as soon as I switch to custom rom, the network goes away. Please help

DoHave a look at your IMEI status with *#0011#
If it's NG you may have inadvertently corrupted your EFS partition. I dealt with that myself recently. If that's the case, if you've got a backup of the EFS, try to restore it. If not, backup your EFS to your PC or another secure external location, in case of worse emergency later. Then empty your EFS folder except for the FactoryApp and prov_data folders and their contents, then flash a clean firmware with Odin.
This can backfire. Read-up and Backup before proceeding.
I have no further expertise to offer. I just blundered out of messing up my EFS during flashing.

Yes I have backed it up before but this case isn't about that. I have the proper IMEI number. I'm just not getting signal and it's becoming really frustrating now.
I even tried going back to the stock ROM but I'm not getting any signal there either. Please see the picture attached

I seemed to have the proper IMEI, too, but it's status was NG anyway. Check *#0011# if you haven't yet, to verify.

*#0011# doesn't work for me but *#06# does and this is what it shows
If you can figure out how to get into servicemode on your device (which is what *#0011# does on my device) then you can check the IMEI status, or if you're confident you can restore the EFS partition try the method I described above.
Beyond that, I'm a virtual noob. My only counsel is to be patient and cautious. Someone with actual expertise may advise you yet in the sub-forum for your device or a thread discussing a similar problem.

The code for me for service mode is *#*#197328640#*#* but I can never get to open it. It just looks blank
There may be other ways to verify the IMEI Status, but that is beyond what I know. Someone more expert may have advice.

Also, I can find FactoryApp but I can't find prov_data folder. This is what my folder looks like. Can you send a picture of yours
If your backup is of your recent, working setup, it might be interesting to compare it to your current EFS. I have no suggestions as to how to inspect the contents of a backup.

I'm quite sure there's nothing wrong with the IMEI number. I have confirmed it multiple times. I just feel so helpless. I don't even get to know if someone's calling me. I just hope I can fix this ASAP

This is not a backup. This is the actual EFS folder. Anyways thanks for the help. I'll keep bumping till someone else sees it
Also I would like to add that the network sometimes bounces on and off after a reboot so..
My IMEI seemed correct as well. The problem was with something in the EFS partition which resulted in IMEI status NG, and I only discovered this was the issue after seeing the actual IMEI status assessment by the servicemode. I repeat: the IMEI numbers shown by *#06# didn't indicate anything was wrong.
Should you proceed along the path I suggested, make sure to flash a fresh firmware from Odin directly after. It seems to be required to restore the EFS after the procedure mentioned before.
Google "FactoryApp" and "prov_data" before proceeding.
Beyond that, good luck.

Btw I did try that code when I had flashed back the stock ROM and it showed IMEI Certificate PASS. I'm sure there's nothing really wrong here because as I said the network sometimes bumps on and off after reboot
I have a question what is the baseband number on the phone? My ROM hasn't been updated for sometime now and I have got official updates for the stock ROM. Does the new update for the stock ROM come with new baseband? Will flashing the update for the stock ROM update the baseband too? Or is that in the kernel? I've read that updating the baseband usually fixes network problems. Please help me fix mine
I just extracted the new update for the stock ROM but I couldn't find any modem.bin file in there. There's just usual system, recovery,etc. If I don't have the modem.bin file how can I flash the radio/baseband? Should I just flash the firmware via Odin through AP or CP option?
