[Q] Lost IMEI

Guys, need some help here.
I´m noob, After try some custom Roms, scripts, kernels, etc, I lost my IMEI. Device is working fine, but can make emergency calls.
Try many things to recover it, i flash a froyo stock rom, GB stock, try diferent programs and read a lot here in XDA.
Cant find EFS folder, even using Root Browser.
I didn´t know that was need to back up the EFS folder. I only had CWR backups, and even this not works.
Maybe there something especific for Galaxy Fit?
Thanks for any help!

Try install stock ROM with 4 files via ODIN, after CWM via ODIN and after custom ROM which you want.

Tried exactly this using a stock froyo rom, doesn´t work...

Are you tried Gingerbread with 4 files?

No, i tried Gingerbread (one package) and Froyo (4 files). Is there any diference?

I do not know. After this what I suggested, custom ROMs should work normally.

I will try again, where i can find GB in 4 files?
thanks!

Here: http://www.sammobile.com/firmware/
In Search write s5670, and download ROM for your location.

Ahhh this is something that even I was perplexed with...
A lot of people have reported this already, but we haven't made headway in this area...
In samsung phones, IMEI is either in efs or in csc, but none of us have had a closer look at this...
Hopefully, we'll be able to have ways to backup imei in the future...(no promises, though)

I hope too, for now I'm trying many ways to recover my IMEI, nothing works...

Updating: I use EFS Pro V2 http://forum.xda-developers.com/showthread.php?t=1308546 , and finaly have my IMEI back. I post it cause coud be helpful for others.

Can you be a bit detailed?
Maybe list the steps.
This would help a lot of people.

Well, sorry for my bad english, will try to explain step-by-step: i instaled the app (EFS Professional) in my notebook, conect my device via USB, debuggin, ADB too.
Open the app on computer, select Qualcom.
Click on Qualcom NV Tools, a new box will apear.
Click Connect.
First i try Imei Repair box, insert manally the IMEI number and click Write IMEI,doesn´t work (and i don´t know if to digit IMEI number was neccessary, but just in case)
Close this box, go back to initial box and click NV Restore. The fone will reboot and it´s done. IMEI original number was restored.
I don´t know if maybe just clicking NV Restore as first step will do all the job, maybe. But I was "exploring" the options and thats works for me.
I hope it be helpfull

Have a couple of thanks, coz this was helpful.
I'll ask around if somebody has lost their imei and we'll try to cross check this, make it noob proof and then have it added to my guide to help the poor souls who might need this in the future

As fast as I now everyphone has different efs flashing different efs might payment lyrics brick your phone

yes serial and imei would be different but layout surely would be the same, if we can revert original imie then there shodnt be a problem

Hi
How would this help if your efs is corrupt?, or does it fix it when you restore?

Hi,
The link was ment for anyone willing to take a backup of their efs for you. Just to make it easier
I would do it, but i don't have a computer available before new year.

Ok thanks no problem, I did try installing another modem and messed around a bit what then happened was imei unknown and baseband unknown. I reinstalled stock and unikernel and everything came back. Im lost on what to do next

{URGENT} Need someone's EFS folder and NV_Data.bin

I ran into an issue where after flashing the Marshmallow firmware from a G925F rom on my SM-G925P phone getting the error "device does not have drk please install drk first"
EFS folder, nv_data.bin, and cert are corrupt. I simply need someone to send me their EFS folder so I can get my phone to accept these firmwares once again and hopefully I can start developing a few roms. Here's hoping there's someone out here who wants to help.
E-mail: [email protected]
Thanks

Can you reflash the correct version and fix the problem?

Unfortunately it doesn't change anything. When I flash the SMG925P variant firmware it still gives me the DRK issue. I've been told my EFS was corrupt and I didn't have a backup.

bump, no one? I'm not using a sim card or anything so you shouldn't have issues.

Would a backup through twrp of efs be sufficient? If not let me know what way would be acceptable.

I really need to figure out how do you flash the .bin file. I tried to make it an Odin package, fail... zip package.. no meta-data, partitions app... backup must be an .img. What are people doing to flash .bin? Could I take a look at your nv_data? I have the Sprint version with null imei. I was trying to fix a corrupted usb drive from twrp and the stupid thing mke2fs to my efs somehow. Now I can't do anything about it yet until I figure out more than I know.

It didn't fix it yes that's true, however what is there to do?

IMEI=0 restore with QPST, provided a QCN is available?

First things first, I'm sorry for opening another thread on this but I feel the other ones weren't headed exactly in the correct direction.
A little background:
I was trying to downgrade my XT1541 to Lollipop since 6.0 was really bad and I got frustrated and used
Code:
fastboot erase all
The result was I erased my IMEI and I haven't been able to connect to a network carrier since. The problem can be solved by re-writing my IMEI but that's the difficult part.
What I gathered so far is I can use QPST, backup QCN, go into HEX and change IMEI there, then restore the QCN back to my device. The problem is I can't locate the IMEI in my QCN since my IMEI is now simply 0.
So in all, could someone make a backup of THEIR QCN and send it to me? I would flash it to my XT1541, locate the IMEI (since now I would know what I'm looking for), then change it back to my own.
Does that sound like something that could work? Can anyone help?
UPDATE1: Noone sent me their QCN however I did try to restore the one I backup up (which still has an IMEI=0). QPST Software Download reports
Received an invalid command from the phone.

I tried using Qualcomm NV Tools (from EFS Professional), which reads all the information correctly, however when attempting to write the following appears
Cannot Write: NV_UE_IMEI_I
Error: NV_ERR_BAD_SECURITY_STATE
Click to expand...
Click to collapse
So getting another QCN won't help as it seems that I can't write the IMEI (qcn) back to the device...

There are only two possibilities of fixing this... a 50/50 chance that a full factory flash will restore it (don't know how, but it does sometimes). If that doesn't work, then you need to send it to Moto for repair.

Well, unfortunately that leaves option 2... or turn it into a media play and buy a new phone.
Funny how `fastboot erase all` causes such a pain for some and not others... but once your IMEI is gone, there isn't much you can do. Moto kinda screwed the pooch on that one.

Hello, did u try Xposed IMEI changer? Maybe that will be a native fix for this issue.

Hey, couldn't get any results with the xposed module

Just one bump

One last effort, not a bump. If anyone can direct me to commercial services for repairing the IMEI i'd be very greatful. Official Motorola Service wont repair it for me btw.
Thanks

try this guys
