Hello again folks,
I opened another thread regarding this problem I have, but since no one replied, I did some research and made some progress. Here's what happened: my cousin bought me an gt-i9301i in the UK, made a 5 min call or more with her SIM as instructed, and sent me the phone here in Brazil. When I received, the phone asked for the SIM network unlock PIN. I tried to unlock it by myself, with no success. Before sending it to a local store to try unlocking it, the only things I did were flashing a Chain Fire rom to root it, and then flashed a Stock rom to turn it back to its original state before sending it to be repaired. The store "unlocked" the phone, but now my IMEI is gone.
In the last days, I'm trying to fix it using QPST and the EFS Professional tools, as instructed in this thread (http://forum.xda-developers.com/gal...warning-guide-backup-restore-imei-nv-t1946915) and also this external tutorial (http://droidmodderx.com/galaxys3/?page_id=79).
I did the following procedures on my phone using its stock ROM, with USB debugging on, and tried with both root access turned on and off.
This is what I achieved so far: I connected my phone to QPST (by the way, the working code for my S3 Neo phone is *#0808#), and after turning on the RNDIS + DM + MODEM mode on, made a backup using the "Download" QPST tool. I tried to edit that backup (the file has about 260 Kb) using the "RF NV Manager", as instructed in the second post I mentioned, by going to the item 550 and writing my IMEI in blocks and everything, and then creating a separate QCN file. When I try to restore the new file using the Download QPST tool, which supposably has my IMEI number on it, I receive the message "Received an invalid command from the phone" at just 1%. When I try to restore the original backup, it goes to 100%, but in the end, I receive the message "Could not Reset the Phone. Communication Errors Occurred". When I try to edit my IMEI directly on the phone, when I reboot it and turn it back to MTP + ADB, my IMEI is still showing nothing.
Using the EFS Professional Qualcomm NV Tools, when I try to write my IMEI on the phone, using the Secure Ops. tab, I recieve an error message saying NV_ERR_BAD_SECURITY_MODE, and when I try to edit my QCN backup, I receive the message "Unable to write selected byte data to QCN Backup!".
Any thoughts on what else can be done to restore my IMEI?
Thanks
Hi!, i have a LG G2 D805, that after to flash Lollipop Cloudy G2 3.3, my phone lose the IMEI, ESN, MEID.
I tried to rewrite with many programs this data but none conect. I tried with QPST, ESF Professional, CDMA Workshop, DFS CDMA Tool etc and all programs find the port connected, but when i want to read the phone, the connection drop. None program can to recognize that the thing conected is a phone, neither recognize the chipset.
In other words, the com port connect fine, but when i click in read phone information o any rad, says "the phone connection has be lose"
In not official SAT they tried with OctopusBox and had problems to connect again.
The phone works well , except at times when the PC not want to recognize the MTP mode , or the phone not save the hour change after restart.
Any method to recover IMEI and this data?.
I not have EFS backup.
Thanks!!
You must be on stock rom to do this things

You will have to send it in for repair if you dont have a backup and a complete clean flash of the stock firmware doesnt work. Anything else is illegal depending on what country you live in.
I tried connect with clean and stock rom kdz of kitkat and nothing, not connect.
Did you try flashing your modem via twrp? I think your modem is corrupted.

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

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?
