P970 Noob Flash with No Backup and now no IMEI & Network

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

if you can tell me how to extract i will do it for you.
and, if you can help me, i need the system image of the build kxe21.187-42. should be yours as well.

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.

Here you go, had to put it in a folder (but extract, it's not flashable), hope it helps.

Sadly it didnt.. Your phone was an US phone correct? It stil shows no Sim no reception.. IMEI is gone too from the info screen
Could you try doing this for me ?
su (press Return)
dd if=/dev/block/mmcblk0p10 of=/sdcard/modemst1.bin bs=512 (press Return)
dd if=/dev/block/mmcblk0p11 of=/sdcard/modemst2.bin bs=512 (press Return)
I remember my script deleted thos, and maybe that will do the trick

Radixtrator,
What exactly you flashed as wrong radio: NON-HLOS.bin ? fsg.mbn? Both ? Please explain in more details.
And how you flashed modem file, provided by fnut6969?

My apologies, I now notice you were looking for the XT1092 modem, I guess that shows how important it is to actually read posts thoroughly.

I thought the factory images where available on the motorola site but I see now that they aren't. Maybe you can tell me how to create a system dump to return to stock (I have an xt1092)

The absolutely most awesome thing you could do is give me a Full Nandroid Backup ( without data) especially including the EFS Partition, because i believe thats whats wrong with my phone... That would be incredibly awesome

I don't want to unluck just yet. I didn't even know btw moto has an efs partition too, I can't see it

The Problem is, there is no german firmware ANYwhere on the Internet.

Well one suggestion is to factory reset without the sim and set up the phone with no sim. It won't hurt to try

Efs erased without Backup

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.

[help needed] needed backup for unbrick

I bricked my device. Twice, first time i wrote g925f bootloader and unbricked after some time, opened thread about this:
https://forum.xda-developers.com/ga...t/guide-repair-hard-bricked-devices-t3573865/
But second time i wrote 5.1 At&T sboot and phone is now completely dead.
Tried everything, even build uart cable and converter...
I read here in xda that it is possible to unbrick with usb otg, i don't believe in this, but it is last option, can't hurt to try...
To try this i need backup of some device with 6.0 firmware with eng. boot (without root shell is impossible to dump backup)
And then in root shell type this for making backup:
adb dd if=/dev/block/sda of=/sdcard/mmcblk0 bs=1024 count=1048576 (pulls a 1GB raw dump)
adb pull /sdcard/mmcblk0 (saves it to the hard drive)
If someone is able to help, please upload me a backup.
I wrote all this here, it has more detailed axplanation: https://forum.xda-developers.com/at...-samsung-g920a-s6-g925a-s7edge-t3564637/page4
Edit: Didn't unbrick phone, at the end sent it to Samsung for warranty repair and they replaced charging board, motherboard, some coaxial cables (black and blue) and battery.
At least i have almost new phone now, Samsung accept warranty, didn't have to pay for repair.

If someone is willing to help and don't know how, here is rooted (adb only) odin flashable image:
http://www.mediafire.com/file/divdnst45jw1jp7/G925AUCS5DPJ1-rooted-upgrade.zip
This WILL NOT delete data, but use only on any 6.0 firmware.
After that just run bck.bat from this archive:
http://www.mediafire.com/file/uic3e6ea48bolox/adb-backup.zip
This will create 4. files. I need this files to try to restore my phone, but also is useful for making backup if someone likes to play like i played with my phone...

IMEI starts with 004, No WiFi, Bluetooth, and Cellular

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
