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.

Yes I did. But I don't know how can I restore the /efs folder that I backuped before flashing...

OK, I don't know what I did and how I did it, but all of a sudden my SIM card is again recognized. Man... I think I lost few years of my life just now... Huh...
Anyways, as promised, SkinBobUk if you give me Paypal link, I will send you $5 for beer. I don't know if your answer helped or not, but you are the only one that tried to help so... Can I buy you a beer?
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
10. adb shell
11. su
12. rm /efs/nv_data.*
13. rm /efs/.nv_data.*
14. cp /sdcard/nv_data.bin /efs/nv_data.bin
15. reboot

I have gotten myself into a mess and having upgraded to JP6 my SIM card is no longer recognised. Has anyone else had this issue and does anyone know of a Fix that they could give me to sort this mess out.
Thanks

Don't panic, this is easy to fix..
Do a reset, cache erase from recovery mode (Volume up + Home + Turn on).
Root the device, install busybox and run it, install andoid terminal emulator the execute the followings in terminal emulator:
- su
- busybox chown 1001:1001 /efs/nv_data.bin
- reboot
That is it.
EXCELLENT!,
When you say wipe the cache is that option called "wipe cache partition" and where can I download busybox from etc? Im a bit of a noob with the fixing my screw ups business.

Yes "wipe cache partition".
Root using the program from here (if not rooted yet): http://forum.xda-developers.com/showthread.php?t=803682
Busy box and emulator from the market. run busy box and click install and wait till it installs then run emulator. You must choose allow when prompted in both programs.
Hi, did all of this, it would not accept the reboot command so I turned the phone off and on. I dont know if the reboot command is integral to solving the problem but it has not worked. Is there something else I need to do?
it says
---------------------------------------------------------------------------------------------------------------------------------
change the owner and/or group or each FILE to OWNER and/or GROUP
Options:
-R Recurse
-h affect symlinks instead of symlink targets
-L Traverse all symlinks to directories
-H Traverse symlinks on command line only
-P Dont traverse symlinks (default)
-c List changed files
-v List all files
-f hide errors
------------------------------------------------------------------------------------------------------------------------------------------------
What does this mean?
I don't think that you have executed the commands right, maybe because that I should have written them more clearly.
Execute in emulator:
su
(hit Enter)
Choose "Allow" and exit the program when done.
Start Emulator again and execute:
su
(hit Enter)
busybox chown 1001:1001 /efs/nv_data.bin
(hit Enter)
reboot
(hit Enter)
The phone will reboot and it will accept the card if the nv_data.bin staill intact. Try the steps above and I hope that every thing is right.
Unfortunately it has not worked. Have you got any more ideas? I appreciate your help with this.

Did the commands execute right, no errors?
If so then check the IMEI number: Click on Phone in the home screen as when you dial a number and dial *#06# see the number that comes off, is it your correct IMEI number?
There is no IMEI number there, which is slightly worrying haha
no errors either

in this case you might need to read here: http://forum.xda-developers.com/showthread.php?t=780509
It might be that the nv_data.bin file in your mobile is damaged, I'm only saying that it might be that, the only way to know for sure is to check the IMEI number in the phone under "Settings"--> "About phone" --> "Status" if there is no IMEI number then a reflash might correct that, if the IMEI number is like 000044...etc then the nv_data.bin file is damaged and can only be corrected if you have backed up the /efs folder. Please read in the linked thread to find out before doing anything.
I had this problem. I just reset my phone. When it rebooted it installed Sim Toolkit and now it works fine & reconises the Sim. Do you have Sim Toolkit installed?
I had this exact problem spent 2 hours trying fixes etc, I had my SIM card in the wrong way around, I was so used to putting it in like my old phone i did not notice the little picture saying the way to put it haha I had taken it out to flash a new ROM and assumed it was the ROMS fault cause it stopped working
no mate it doesn't. Just done a quick factory reset without success.
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.
Best Regards.
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

i had similar problem when installing cm10 rom and cici rom, after flashing those roms my device had no IMEI and no network, it didnt even rcognize my contacs in sim card. the strange part is that i was able to make calls, but when i flashed back to the rom i had, everything was back and looking good.
i had marvel v9 rom thats runs pretty good.
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.
It started when I tried to reset the EFS (My IMEI was 0) using these commands.
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2
When I rebooted the device as instructed my WiFi was down!
I rushed to check the IMEI and found out it was 004400152020002.
I tried everything to recover it. I realized that in the bootloader menu when I select Bar Code it shows the original IMEI.
Sadly I forgot to make a QCN backup.
Any help or fix would be appreciated
hi bro send dm i have solution. I found a youtube video for fix this
