Hi,
I have a problem with my S5. After flashing a custom ROM I found out that my IMEI is null, and so the EFS is corrupted. I tried to restore it from backup only to find out that I have deleted the backup
What can I do now? I anything? Would restoring EFS from another S5 (with damaged mainboard) could be a solution?
Generally everything works except of phone modem, I have got IMEI written - is there maybe a method to set the IMEI without EFS or a method to create EFS? I already tried sam IMEI changers, but I found out that they only do this on the application level - apps will be able to read different IMEI for licensing, but phone still sees NULL IMEI.
You can't restore EFS from another S5 coz it'll brick your device.

Thanks for answer
So what can I do?
Found sth like this:
Never tried coz never lost IMEI
In the dialer, type- *#197328640# or *#*#197328640#*#*
>You will be prompted into the Command mode, provided On the screen, Select on Common, normally option 6
> Now Select (FTM) Option 1
>FTM is for debugging and testing., (Field Test Mode)
>If (FTM) is on, you will have to turn this OFF
>As soon as you turned this off your NULL or altered IMEI number will be restored
>(Important) Without leaving the Command screen, press the Menu key, the button that’s found left of the Home button.
> Select Key input and enter option 2. In this case, you want to turn it off
>Wait for a minute. This will turn your FTM OFF
> Remove your battery and SIM card for two minutes
>Place your battery in your phone, (important) do not place your SIM card in.
> When the phone is booted, enter the command mode again dial – *#197328640#
>Select the Debug Screen, normally option 1
>After that, choice phone control, option eight
>Click on nas control, option 3
>Afterwards, click “RRC (HSDPA), option 5
>To Fix not registered on network or Null IMEI #, click RRC revision, option 2.
>Choose the released of your phone, here we will choose option 5 (HSDPA only)
>Final step to fix Null IMEI not registered on a network for Samsung Galaxy is to turn off your phone and insert your Sim card
or
>Insert your Sim card, afterwards reboot your phone
Thanks - are you sure about this bricking device?
I already tried this numbers but it always says "No Network", The only instruction that I found was to use *#0011# and it goes into the Service Menu, but it doesn't look like that described. There is something called NVM restore, but it doesn't do anything with IMEI
I am gonnna post screenshots at evening.

Yes I'm sure about bricking. EFS partition on your phone is made for ONLY YOUR PHONE. This is sth like restoring TA Partition on xperia devices. When you flash ta from another xperia, you brick device
Tapatalked from SM-G900F
I read someone saying they had successfully restored a backed up EFS partition from an identical model S5 to another, and it worked
The problem I can see, is if the original gets blocked by the carrier, chances are so will the clone
Not sure about network issues having two identical devices on the same network at the same time, both making calls, might end up like an IP conflict
Pretty sure that transferring IMEI from one device to another is against the law too......

Yes, I also know that is it against the law, but I have a complete phone with broker mainboard (so even the IMEI is written on the back), and I would like to use this opportunity to copy the IMEI from old (broken) mainboard to the new one. It even looks better than the situation when I have got and old case with written IMEI that doesn't correspond to the IMEI on the new mainboard.
The mainboard is broken that way, that there is short-circuit somewhere and the CPU is constantly using power and it get's really hot, so it use useless.
I am trying to flash EFS, let's see what is gonna to happen

1. Tried flashing EFS = nothing happened
2. Tried flashing EFS + Modem + ModemST1 + ModemST2 = nothing happened
3. Restored android to STOCK
I can't get into the service menu.
The only Service menu that I can get into is this one, but there isn't any fixing IMEI/NVRAM option
Code:
*#0011#
Menu > Back
Menu > keyInput "Q"
Menu > keyInput "0000"
Wait for few seconds

Hi,
you have 2 options
1. Use Samsung Kies which will repair you efs
2. Flash with Odin the official rom 5.0
If you install another efs, the data installed may be not work, even if it is same model. In S5, nothing to do with the IMEI
You can also root the phone and with adb commands, erase all the efs
you can also use Z3X tools
Hi,
Thanks - some new ideas
So if I understand you correctly, I have 3 options:
1. Use Samsung Kies which will repair you efs - how to repair EFS with Samsung Kies?
2. Flash with Odin the official rom 5.0 -> I tried flashing oryginal 4.4 and it didn't helped. Should flashing 5.0 help?
3. You can also root the phone and with adb commands, erase all the efs - What will erasing EFS will give me? Shouldn't I have EFS partition with some data?
you can also use Z3X tools -> ok... I am gonna figure this out, 'cause I don't know it yet

This does nothing on Galaxy A5!
attached 0011 code screen
Has anybody found the solution? Efs professional gives me error " device connection lost" while using Qualcomm nv tools on s5.
Hello
I have an LG G2 D802 that was working perfectly but some days ago, after a crash with broken screen the phone suddenly show the message "Service Disabled" and the code *#06# returns IMEI Null.
By the time of the crash it was kit kat, and I made a factory reset that did not solve the problem. After that I use LG Flash tool to install the lollipop 5.0.2 rom, but the problem remains.
Then I took a lot of time trying to understand the problem and I found out that it could have a EFS backup, but in fact I didn't have one.
The next thing was root the device (it is allready out of warranty) and use alternative tools. I have tried to rewrite the IMEI I have in the box with QPST , Qualcomm NV tools and did not work.
- QPST (2.7.4.11) works and shows the device but doesn't work the Backup QCN (To get QPST to show the device I needed to apply this with adb shell - http://forum.xda-developers.com/lg-...ct-g2-d800-t3175064/post62250384#post62250384, but it works and shows the phone in the ports list);
- RF NV manager returns and error "NvManager::getNvItemsFromPhone( const string comPort ) - QpstServer::sendSyncImpl - Bad response from phone (DM packet commands 19-24)";
- Qualcomm NV tools works and reads the device, then I write ESN, MEID and IMEI with good confirmation messages, but when I rebbot it remains with Null IMEI.
By this time I am in the search for more wise help and experience.
I also have "Unknown Baseband", and by reading some threads I thing the problem is that the phone has Null IMEI and the tools are unable to writr data to partitions. The only way is to write NV1 and NV2 by dd command into mmcblk0p10 and mmcblk0p11.
The phone works perfectly in all aspects (sensors, camera, wifi, screen) except for the phone signal "service disabled" with an X above the 4 signal bars. I gess it is not a hardware problem
I am struggling with this because it is a very nice device, and I need to bring it back to life before replacing the broken screen.
Any help?
thanks

Today I tried this method with adb shell, to make sure Qualcomm NV tool writes IMEI to the phone...
setprop sys.usb.config diag,adb
ls -al /dev/block/platform/msm_sdcc.1/by-name
dd if=/dev/zero of=/dev/block/mmcblk0p10 (no space left on device)
dd if=/dev/zero of=/dev/block/mmcblk0p11 (no space left on device)
dd if=/dev/zero of=/dev/block/mmcblk0p16 (no space left on device)
Can anyone tell me why the "no space left on device" occurs?
Thanks
Hello!!!
First sorry for my poor english!
I think that you have a bad connection after crash!!!!
1. Remove the Backcover of your phone.
2. Remove the backplastic on upper part of phone using screw driver.
after remove back cover and upper plastic
3. Remove Battery Connector.
4.Remove all connectors except camera connector, Proximity sensor and face camera
After removing connectors
6.Reattach all connectors! Firmly press all the connectors
7.Reattach battery connector!!
Et voilÃ*!!! This is a way I do after losing IMEI and Baseband! IMEI: null and baseband should be implemented!!!
I had tried most method to fix but nothing happens,
Hope to help you!

What should I do? If the same problems on RF NV manager got the same error. bad response from phone. How do i fix it?
Wow! What a coincidence!
I also have a LG G2 (D802) and the EXACTLY SAME problems!
Background:
It's been about a year since I am on Lineage OS 14.1.
Since 6 months ago, I started having issues with my antenna. Sometimes, antenna bar got empty and sometimes I couldn't get 3G signal on locations that I had before (and others had with no problem)
Fast forward 3 months ago and one day my phone couldn't detect sim card and IMEI was vanished. I had to restart it few times to make it come again.
And a month ago, I dropped my phone and screen shattered, Exactly Like you. After changing broken LCD with new one, and also a new battery, I couldn't get sim card detected anymore, No matter how much i restarted the phone.
IMEI was null and no baseband version was showed on about page. Also back of the phone (under camera started to get suspiciously hot.
I started applying pressure to different parts and sometimes phone hanged and restarted and maybe one in 20 times I could get antenna and sim card back.
Things I've done and their result:
Opening the phone numerous times and checked the connectors and unplugged/plugged them: nothing changed
Flashing back to stock (found lollipop kdz and flashed it via lg flashtool): nothing changed
Flashing Radio (Some images were available on XDA): nothing changed
Restoring ROM to an old backup I had (year ago): same as above
Trying to use QPST/NV Tools: They cant talk to modem.
Showing the phone to some repairmen: they cant talk to modem to set the IMEI either.
Still, sometimes by applying pressure to phone randomly, the IMEI comes back, which prevents me to cut hope and drop the phone into trash!
I would really love to know your result! were you able to fix it?

How to Fix LG G2 no IMEI and not detecting SIM Card!
After I posted this reply here, I found a solution on some other topic about how to fix LG G2 WiFi issue. He opened the phone, and applied constant pressure (by putting a tape between WiFi chip and Metal Cover).
And I thought maybe my problem is similar too. So, this is the things I've done:
Download the Service Manual for your phone model. you can find it on Internet. Here is the one for LG G2
Look at the Service manual and find the chipsets related to IMEI/Service Issue. Usually they classify board components based on their common issues. For example, in G2 service manual, in pages 38 and 263, you can see this info.
For LG G2, The chips/IC's related to IMEI and Service were: U2003 (Bypass Booster), U2002 (WTR1605L), FL1014 (B3 DPX), U1101 (SP4T B7), FL1015 (B2/B3 Filter), FL1010 (DPX B20), U1005, U1000, U1001, U2002.
Most of these parts are under a metal shield which can be easily unmounted and mounted back on.
Make a thick piece of Tape and put it between the chips and the metal cover. The goal is to apply pressure to them to stick to the board.
Put the metal cover back on and close assemble the board. Done!
In my case, it worked, although after lots of repair men simply rejected my phone, I fixed it with just a little tape. Now, the IMEI is back, SIM Card is detected the moment phone is on, and I guess the phone consumes less power, since it doesn't get hot anymore.
Why this works? Well when you use your phone for a long time and it undergoes a of of heat/cooling cycle, the pins of some of these chips that tend to get hot, become a bit loose and get disconnected from the board. by doing above instructions you simply push them back.
Hi, so after messing up my NVRAM I've managed to restore my IMEI and there is connectivity, but it's emergency only. It can see the SIM card, but can't connect to a service provider for normal connectivity. I've looked into *#0011# and it says IMEI Cert failed -4, is there any way to fix this, and would it make the phone functional again?
