I am really hoping someone can help me sort this problem. I recently bought a LG P970, and after long await from customs, i received it! On day 1 before even purchasing a simcard i rooted and changed roms. I went through all sorts of roms from nightly cm7 to cm10, nove, aokp etc.. I finally decided i like AOKP Rom and day 2 bought my sim card. SUPRIZE!! no network! IMEI unknown. Unfortunately i was to ignorant to do a backup and i have been searching for +- 40hours now to try resolve this issue.
I have tried the tutty/Hyperterminal.. Does not work! If i dial 3845#*970# and access the hidden menu. as soon as i select CP USB, the pc just makes the insert/ takeout sound constantly and does not install driver, but on AP USB, the sd card can be accessed, my device shows on system and everything is 100%. I have tried this on 2 windows 7 computers. So that option is out.
Does anyone know another way to restore the IMEI? I dont have any fancy box tools, just my pc.

The AOKP hasn't been updated in a while and has more bugs than CM10 and V30 repacks.
When did this start? You can only wipe IMEI if you select "Wipe Entire AP" or something like that on SFT. Does the problem persist on other ROMs? Also no network connection isn't related to IMEI, more likely ROM related.
If your really desperate you can extract your nv partition and hex edit your IMEI in and push back to device. All you need is microusb to usb cable and computer (and a hex editor, but thats free to download ), but I will only do this as a last resort.

Thanks for you reply,
When i bought the phone, before i put in a simcard, i ended up flashing and changing roms, so the next day i bought a sim and there was no network, did research and found out that my IMEI is missing. if i type *#06# then is just says IMEI and no number. I have flashed back to original rom but still no luck. I have tried many things on youtube but nothing works, i tried the tutty to try restore an IMEI but doesn't work,
What do you suggest i do? and is there a step by step guide to resolving this?

This will only work with the P970
Use adb shell from your computer or use a app like terminal emulator.
Code:
echo $IMEI | dd of='/dev/block/mmcblk0p11' obs=1 ibs=1 count=15 seek=8 conv=notrunc
echo $IMEI | dd of='/dev/block/mmcblk0p11' obs=1 ibs=1 count=15 seek=4096 conv=notrunc
where $IMEI is you IMEI
The large bold print is for people that can't read headings that might run this and brick their devices.
Something I learned that isn't mentioned on the forum is that its important to backup your nv partition since that contains info that can't be retrieved after damaging it and nothing backs it up for you. Like MAC addresses, your IMEI etc.
On you computor
Backup using
Code:
adb pull /dev/block/mmcblk0p11 nv.img
Restore using
Code:
adb push nv.img /dev/block/mmcblk0p11
EDIT: Added notrunc to not truncate the rest of the partition

Hey, Thanks for getting back to me. I tried the command on Terminal Emulator and it says IMEI not found and conv disabled. Any suggestion?
Did you try the official LG Mobile Update Tool?
There is emergancy and recovery mod where you can fix it.

I tried the LGMobile Support Tool various times. The recovery module does not work, if i type IMEI adn select check phone, nothing happens. The strange thing is the support tool picks up my phone model as LGKU5900 version V10I. That could have happened with me trying to repair the phone with various programs and youtube videos.
I have tried uninstalling and reinstalling the support tool as well as the drivers but still no luck.... I reflashed the original rom V10F with no patch etc.. but still the Support tool picks up the model as LGKU5900, and when i select update phone, it downloads the update and during installing of update it stays on 6% for roughly 20 minutes then just stops. I have tried this numerous times and same things happens everytime.
If this is of interest to you to, you can take control of my system and check it out via team viewer.

rather try this. included dd might not be up to standard
Code:
echo $IMEI | busybox dd of='/dev/block/mmcblk0p11' obs=1 ibs=1 count=15 seek=8 conv=notrunc
echo $IMEI | busybox dd of='/dev/block/mmcblk0p11' obs=1 ibs=1 count=15 seek=4096 conv=notrunc
and replace $IMEI with your IMEI.
EDIT: The above should repair your IMEI, but if SFT fails to update your phone then it's wrong firmware or HW problem and it will cause problems elsewhere aswel.

Still no luck, it says dd applet not found with the busybox command, and the abouve code i tried {$IMEI | dd of} just disabled my conv, thats all. Do you think the phone has no chance of being network active again?

dd should be included in busybox. What busybox are you using?
The conv=notrunc just tells it not to truncate the rest of the file (in this case don't truncate the rest of the nv partition)
the echo pipes the IMEI to dd which writes it to /dev/block/mmcblk0p11 (your nv partition) on two different spots. I
You need su permissions to write to /dev/block/mmcblk0p11. I forgot to mention that. Otherwise dd will fail and the included binutils dd doesn't always list error messages. Just terminates silently without doing anything most of the time.
You can also try reflashing just the baseband. (The fls file with SFT)
If all that doesn't work then you need to take it into repairs.

I don't have a solution to your problem however I am in a similar situation. I purchased my Optimus Black from an ebay seller located in Hong Kong, it was advertised as an Optimus Black P970. The software version was similar to yours, outdated, so I grabbed a stable gingerbread version patched it with root etc. and flashed.
Upon reboot I had no cellular network, tried two different sims/networks. No Joy. Further troubleshooting uncovered the loss of the imei. I came across this thread and decided to give it a try, it didn't work. I suspect I messed up the command, in my case this was lucky because I was able to see the content of the mmcblk0p11 file using a hex editor. The imei is in there, and it is also in the same location as my Optimus Black P970, I assume it is stored elsewhere as well....
Long and short of this is you and I have purchased the KU5900, the Korean version not the P970, flashing with P970 firmware is what has messed the phones up.
Note. I did try flashing with the only Korean version that was available to me, a V30 something, that bricked the device. It is now unbricked but still shows no imei. I haven't given up but wading through reams of forum posts trying to get info on this is daunting ... My seller has agreed to replace the phone, but I fear I will end up with another KU5900 which isn't any good to me unless I can upgrade the firmware.

I just fixed one P970 with unknown IMEI by flashing it with Octopus box, I think that you can solve it by flashing with original flash file using SFT.

Hi....few days back, I had the same problem....After flashing my phone to V30B(CIS version) which was not available for my phone in my country India, the IMEI then got removed automatically(*#06#- shows IMEI not available), then I installed the latest version V20G which was available for my country then (through smartflash tool) and then got back the IMEI. Try installing the latest version available for your country and do let us know if that solve your problem. Best of luck

OK, I have one BIG problem. Yesterday I flashed XXJPK and all went smoothly. Even rooting the phone went smoothly. Today I wanted to change back my product code but I forgot to remove the SIM card while I was "playing" with the phone and ADB. Now when I put my SIM card in the phone, the phone won't detect it. It just say "No service". I don't know what to do...
I tried flashing to XXJPK once again and rooted the phone again. Everything went smoothly EXCEPT that I still have "No service".
Of course, I tried wiping the SIM card with soft cloth but it didn't help. Please help me because I really don't know what to do...
EDIT: The one who helps me gets $5 for beer
Did you back up your efs folder? Im not an expert but you could try restoring it from your backup. I've read this can help if your imei gets changed during the flashing process.

Lol you dont have to do that mate. Save it or donate it to one of the clever people on here who made the rooting/flashing, etc possible!
Glad you got it sorted in the end tho.
Which phone exactly are you using? What was your stock firmware?
I don't understand one thing:
-> I have a netlocked phone (yes i have my efs folder backed up from JM7)
-> I flashed JPK, no simcard inside
-> I put simcard
-> Everything is OK!
Howcome you got netlocked?
1. enable usb-debugging
2. adb shell
3. su
4. cp /efs/nv_data.bin /sdcard/nv_data.bin
5. disable usb-debugging
6. connect your phone to your pc with mass-storage enabled
7. open nv_data.bin from your internal SD-Card with an Hex-Editor
8. search for KOR and replace both findings with your original product code, save the file
9. enable usb-debugging

I purchased an unlocked, unbranded i9305 S3 LTE and have not been able to back up the NV Data.
I tried this with it completely stock and even though I have tried both settings with DM in Qualcomm USB settings and the port is found in QPST it always says 'No Phone'.
After trying this on several computers, I then installed Clockwork Recovery Mod and Rooted the phone successfully, and still had no luck connecting with QPST with the same 'No phone' message.
I also tried using EFS Pro and the Qualcomm NV Tools, the phone says at first it is connected but the program freezes and then says the phone has disconnected. I tried unticking 'Read Phone version information' and it connects. But as soon as I try to read any data the Rx Tx indicators flash a couple of times in the app and then I get the same Phone disconnected message.
Can anyone help? I have searched here and online and found lots of similar cases but no solutions...
Thank you very much in advance.

I don't own this phone but are you sure you have a Qualcomm processor? From these 2 pages:
http://www.morecellphone.com/phones/samsung-galaxy-s-iii-gt-i9305/304
http://www.gsmarena.com/samsung_i9305_galaxy_s_iii-5001.php
it should have an exynos processor, so those qualcomm tools won't work. (think qualcomms are just some specific models)
Can't you just get into some custom recovery, adb to it from your computer (or terminal emulator) and 'dd' an image from the /efs partition out of it (needs root)?
How i did it:
Opened terminal emulator and typed "mount" to check my mounts. Looked up the one that had /efs on it. It should also say something like "/dev/block/mmcblk0p3" (this is the one on mine, use whatever you got from "mount"). Then do something like:
su
dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img
where the "/sdcard" is the directory where you want your efs image to go. Then you just need to copy the efs.img file to a safe place and you're done.
If you need to recover just do the opposite
su
dd if=/sdcard/efs.img of=/dev/block/mmcblk0p3
Careful with the "if" "of" order, and with what you type. dd is a powerful command and it's easy to screw up irreversibly if you overwrite a different partition by accident.
Another method, I've manually copied /efs file contents with root explorer to my sdcard and later to my computer and was able to use them to recover my phone (had an app wiping my /efs by accident).
This is how i did on mine and worked but i've heard those qualcomm's (if you really have one) have a different method and what i'm saying may simply not apply
Thank you for your response. Unfortunately even though it does not have a Qualcomm processor it does use this chipset for the modem I believe.
I've been following the instructions in this thread http://forum.xda-developers.com/showthread.php?t=1946915 but not having any luck. The phone is fine but it is not recognised correctly in QPST or EFS Pro....

You have to have USB Debugging enabled, then check adb for your device, type the following:
1. adb shell
2. su
2.1 Grant su permission on your phone
3. dd if=/dev/block/mmcblk0p7 of=/sdcard/modem.bin bs=4096
4. Choose a file explorer you like and grab the modem from the sd card. its probably in /sdcard. +
If you could do that, i would be SOOOOOOOOOOOOO thankful. I dont have the System Image, i could give you a nandroid backup though
Tomorrow i try this. Is possible to do this only with titanium backup?
Otherwise i have to find a windows pc, i have only a macbook.

Well one suggestion is to factory reset without the sim and set up the phone with no sim. It won't hurt to try
Please put pit files for SM-G800F online... i erased efs file without make a Backup... i cant make and receive calls and i dont have network.... please any solution ??? Can i type my imei manually into phone?
Factory reset then reflash stock firmware via Odin. Should regenerate EFS.
No.. I make it but no successfull
Using the EFS of another device would be illegal as the IMEI goes with it. Are you absolutely sure you performed a factory reset from recovery, wiped cache and reflashed firmware form SamMobile? This worked on a Note 2 the last time I had this problem...
Phone info+ app show me no build date, no product code, no Hardware rev. and show me wrong imei number..... its curios.. i make varies factorys resets, hard resets and i flash via odin stock rom....
EFS PIT ??
Could you post the result of the following command in a terminal on your phone?
Code:
mount | grep efs
In the terminal i put your command... without su and with su .. .. I have busybox installed....
Partition itself seems fine then. The following should just return blank. If not, you need to wipe the partition again.
Code:
su -t ls /efs
Efs
Terminal
Till now the commands gives answer... Till now everything fine my friend?
Your imei is ok, not generic number or empty....
The IMEI should be fine if the command returns non-blank. The IMEI I saw on your previous screenshot looked like that of a demo model, which means it was generate due to the EFS partition being unreadable. If you still cannot connect you may try EFS profressional if you haven't already.(Backup current on backup tab, head over to Samsung Tools tab and in other tools select "Format EFS folder". After this flash firmware file in Odin before booting up again). Otherwise I'm afraid to say you may need to take it to a service center.
I did a tutorial for backup in two ways, search in general threads
Did a little research. Seems Samsung (or carriers) has made IMEI repair impossible for S5 and up(including all variants) without a service box. Seems like a service centre is the only option for now in the absence of a backup. Apologies.
I have the same problem with my S5 SM-G900F, IMEI NULL and i think the EFS partition was deleted without backup, more infos in the screenshots.
I dont know what to do guys, help plz.

Again, the only way to repair the EFS on newer Samsung devices is by using a certified Samsung service box, which, unfortunately, costs money. Samsung service centers will have this equipment, but will obviously charge for its usage too. If you manage to get your hands on one via other means, there are plenty of video tutorials around showing how to use it. It should only be a matter of time before a tool is designed for use on a PC, but for now, there is no other option. Sorry for your inconvenience and please ensure you use the correct subforum next time as per XDA rules.
After bricking my device like 10 times, I realized efs backup is very neccessary. so i thought i should post it, so more people can back it up.. efs have major details like meid, imei, serial number, config, diag settings and radio settings, etc etc.. its something like registry in windows.
you can backup efs via adb, root is required..
Code:
adb shell
su
dd if=/dev/block/platform/f9824900.sdhci/by-name/modemst1 of=/sdcard/modemst1.bin
dd if=/dev/block/platform/f9824900.sdhci/by-name/modemst2 of=/sdcard/modemst2.bin
or you can also backup via this code :-
Code:
adb shell
su
dd if=/dev/block/mmcblk0p24 of=/sdcard/modemst1.bin
dd if=/dev/block/mmcblk0p25 of=/sdcard/modemst2.bin
done..
Restoring efs if you messed it up..
Code:
dd if=/sdcard/modemst1.bin of=/dev/block/platform/f9824900.sdhci/by-name/modemst1
dd if=/sdcard/modemst2.bin of=/dev/block/platform/f9824900.sdhci/by-name/modemst2
or
Code:
dd if=/sdcard/modemst1.bin of=/dev/block/mmcblk0p24
dd if=/sdcard/modemst2.bin of=/dev/block/mmcblk0p25
RESTORE EFS AT YOUR OWN RISK, I WONT BE RESPONSIBLE IF YOU BRICK YOUR DEVICE. Though major will only flash it in brick mode
Good guide mate. I learned on my g2 that efs backup are important. Killed 3 diffrent g2s with crazy ad type expeirents
I tell errbody dont matter wut phone u have backup the efs.
Back it up. Cant say it enough. Even if u dont learn how to restore it now. Back it up

I actually bricked my phone like 10 to 15 times in 5 days, just to enable extra bands on my phone. i even extracted qcn files from h815, h8111. i was close untill i bricked it again, while playing with sprint policyman which have policies to connect to which band and stuff.. i followed a way from some chinese site and damn.. no qpst, no dfs, no tool were able to read, no imei, no meid, everything on my phone was unknown.. i flashed zv6 tot again, still i wasnt able to restore..
but eventually after going to marshmallow fixed, zv9 flashed new policyman.. THATS WHAT made me backup EFS>> cause in download mode you cant even restore nv via DFS. or qpst. no tool gets connected to the device except restoring via DD
till yet one guy was able to add extra band on sprint nexus (its just not adding band via dfs), it something more.. . and i learned his patching way, basically he extracted parameters from variant and added it on sprint nexus.
soon i will make a thread of my finding about it..
Missing a 'd' in your restore snippet
Code:
d if=/sdcard/modemst1.bin of=/dev/block/platform/f9824900.sdhci/by-name/modemst1
dd if=/sdcard/modemst2.bin of=/dev/block/platform/f9824900.sdhci/by-name/modemst2
