Hi XDA i have flashed recovery-clockwork-5.5.0.4-ariesve.tar and then new beta ICS rom, after reboot no phone signal and no show IMEI but WIFI work.. please help me. thz

I'm not a samsung user but try to push the phone.apk and dialer.apk and contacts.apk from the orginal rom maybe it'll help

i have restore original firmware and nothing, no signal. i'm not sure but what about EFS Data restore without backup ?

Got the same problem here. Tried to install different modems but it didn't help. I'm out of ideas at the moment.

how to install different modems ? install another rom ?

restore efs backup if imei is lost
if you dont even know how to flash another modem maybe you shouldnt have tampered with ur phone to begin with
and if u do not have efs backup maybe you shouldnt have messed with ur phone since its first thing you do after you have rooted your phone

here is something about losing efs data.

another problem of device is the Random Reboot or Auto Shutdown...have any idea for this ??

Magic DEVICE Imei and Baseband restored but sim card DIE

You have to reflash a GB-Rom,i.e. JVU. Then everything will be ok. And after that flash a ICS-Rom which not makes disappear the IMEI and then, without wiping you may flash this special ICS-Rom which caused that issue. Now everything should be ok. That was the experience I have made.

[Q] Survived from brick but i ve lost my IMEI

I tried to install the new version of CyanogenMod Snapshop but unfortunately afte the reboot of my LG G2 D802 the mobile phone bricked.
I read a lot around the Internet and finaly i succeeded to unbrick it. Th problem now is that i do not have IMEI (is null now). I read that there is one program that you can fix your disappeared IMEI but cannot work in my personal laptop. Do you know anything how to repair and fix my IMEI with my previous official IMEI (i have it in the box that i bought but i didnt have any backup of it).
Thank you

I am having the same problem. I was loading a milestone version of a rom and when it loaded after wiping there was no service whatsoever and everything is null. I understand it wiped the efs and I dont have a backup. I also understand that we can change the info back with the numbers off of the original box using dfa cdma tools. I have the program but my question is the 000000 code does not work when i try to unlock the phone. Anyone with any experience with this program that can help me to re write my meid???

Which program do you have?

Dfs CDMA tools

I don't have any personal experience with this, but I have done a ton of reading on this problem and it's become my biggest fear. From what I have gathered you have very very little chance of fixing this yourself. It most cases it goes back to the manufacturer. Can you tell us exactly how this happen?

I have no idea, i have been rooted for months and swapped roms like crazy. I wiped and installed a new rom and then it was getting no service so i tried to update profile and said it couldnt. Then check in the settings for the baseband and meid and unknown was shown across the board. Trying to figure it all out now!

I have had the same thing happen what cm did u install I had a d802 version on my ls980 restored it but now it will only accept a d802 modem and the signal is weak and drops out but it did show my ESN and imei and baseband again instead of unknown if I would have flashed it with a ls980 modem

Have you tried restoring a backup?
Sent from my dr87 v7 powered, Mahdified LG G2 (D801)

My problem started when I tried to update my LG G2 D8002 to the latest Cyanogenmod Kitkat Snapshop and i stuck in clockworkmod recovery loop after returning in CWM to take backup. I tried to connect it to my Laptop but i cannot have any access in my files via my laptop. The bad thing that i did is that i formated everything in my mobile (as you can see and my IMEI too) to make a clear installation of a new rom after the brick. When i entered my new ROM i realized that i have everything apart from my IMEI. So that i do not have any network-signal in my mobile but a connection to Wifi
The program Dfs CDMA tools and Octopus Box does not work in my desktop. (Any idea?)
Do you have any idea how to repair it? I read that there is a folder (nfs i suppose that encode inside the IMEI). So, if someone find this folder can upload it somewhere? Probably will find a solution to solve it.

i was solved problem with no imei :
make full buckup from TWRC in another LS980
restored that buckup in bricked phone (make first buckup on it, to know name of folder, and take to that folder buckup from work phone)
sorry for me English

Are you sure that this works in all devices of LG G2?

[Q] How do I modify QCN files?

Hello I've been trying very hard to change an imei in a QCN file of an S4. I've seen that the later versions of qpst doesn't support editing as they say but I've also tried EFS Professional but no luck. I used nspro to write the same imei as back of the phones to unlock the phones and flash a qcn file with qpst but it changes the imei and I don't want that as it's supposed to be the imei of back of the phone always. Hope I get help, I've been trying this for weeks and googled too much that I couldn't figure out and wouldn't work at all. Thanks for reading!

(HELP) with NV DATA

Hey Guys I need some help with Nv data (EFS )
The NV data baseband is I9500UBUAMDE nonetheless my firmware baseband is I9500UBUGNJ1
I think this is why my phone do not have a stable conection with cel-towers...
So I need to know, how to update the nv data without corrupt it?
Kindly regards,
AG

Just flash a stock ROM using Odin. This will ensure that the bootloader and modem match.

Already did it some many times... Without results...

The phone is missing the imei and MAC address?

No one is missing...
Phone signal Goes out and in.
However while the phone has signal. I can call and navigate on internet..
Do you need the efs folder?

If the phone has an imei, then it seems like the efs folder may be fine and something else is happening.
So flashes are successful in Odin?
Could the phone be blacklisted? Was it ever dropped? Tried a different SIM card? Tried our SIM card in another phone?

Ok, I have to be honest... I was on 4.4.2
I try to use galaxysim unlock. However EFS was v2 and I restore a v1 efs folder in order to unlock the phone. It works. However after upgrade to 5.0. It start to fluctuate the signal...
Note: v1 and v2 are versions in matter of security of the EFS folder...
That is how this how begins...

Did you restore the original version 2 efs? Do you have a backup of the original efs? If not, I'm not sure if an nvwriter will help.

I think I do not have one...
What should I do?.....

I'm not sure what to suggest. Maybe Google nvwriter and see if it works with your phone.

IMEI lost?

Hello, I flashed a stock through MiFlash, but it gave an error, I flashed a stock that I already had to backup, B13 MiFavor5, but when I search + # 06 # I get IMEI 1-2 unknown, I have EFS backup, two doubts, only flashing a compatible modem to recover the signal from the operator? or restoring the EFS partition ?, if you restore EFS, how do I do this?
(I have backup of the EFS folder)

Flash the A2017 modem first. If it doesn't work then use the EFS backup

You can flash an EFS backup with the EDL tools ,I've used it for back ups and restoring ,seems to be the most reliable method for flashing to me . Easy to set up as well . Read the forum page very carefully and you should be fine

Hello, first I want to thank the answers, and I was able to recover the IMEI by flashing the modem, but it is different from the one specified in the box, and even recognizes the chip from other operators, but specifically the one I use does not recognize it.
two questions: Is there any problem with the IMEI being different from the one specified in my box ?;
How can I make this specific SIM work? (I already tested it on other devices and the SIM works.)

At some point your device has been factory replacement chip set put in and this prosuss has cleared that up this is why the IMEI number has changed.......
