Unlocked Phone locked again

Hi there
I Unlocked my vibrant about a month ago amd this morning I powered it on and I was askef for thesim code numbers again. I was just wondering if anyone would know what would prompt this or have had this problem? Or if this is normal

I am going to unlock it again, but I just dont want to have this problem again.
Or is there anything on my phone in the settings I should have set off , so that phone will not automatically go locked again. Some how I am thinking maybe Bell might have put something on the network that was downloaded that changed the NV_data and re locked my phone... Not sure though... Any thoughts? Never heard of a phone that was unlocked being locked again randomly.
I used ADB Shell and changed the NV_Data file and it unlocked it for me.
I did not type in any 8 digit sim code. I have a backup of my original NV_Data file. For unlocking it should I copy and paste it back on to my phone or try to unlock it with the NV_data file that is currently on there now?
It is rooted but still in JFD, I am thinking of flashing the phone again to erase everything and start back fresh. The phone seems a lil buggy and slow.
Any help would be appreciated.
Thanks!

[Q] Can't unlock phone with code

So the story is I switched from telus to wind, what I did first was the QPST AWS band unlock thing, that went smoothly but afterwards I was unable to unlock my phone. I know that I can't reach that special menu because of the latest firmware samsung released which blocked it but I even got a code from telus which I know it's correct, the thing is it doesn't work for some reason... "network unlock request unsuccessful" I tried everything, first I did a factory reset, I restored the file that QPST replaces which I was sure was the source of the problem but no luck there. I rooted my phone, still nothing. I contacted samsung and asked if there was a way to completely reinstall everything, I mean make the phone a clean slate, they said nothing can be done besides a factory reset (officially anyway). So I'm stuck with a locked phone that won't unlock with the unlock code. Anybody have any idea what I can try? I have a brand new galaxy s4 that I can't use, to some extent it's heartbreaking...

I did some more research and I found that its possible that the device is "frozen"? And that you need some unfreeze code, mck "manufacturer control key"? Anyone know anything about this? I'm dead in the water, I've tried everything I could find

[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 can I repair my IMEI on i9301i?

Hello folks,
I've read A LOT of threads here at the forum about repairing/recovering IMEI, but none specifically for the S3 Neo (GT-i9301i). Here is what happened with my cell: I bought it in the UK, brought it back to Brazil, and noticed that it was network locked (I did the region unlock while in Europe). Tried to unlock it by myself, rooted the device with ChainFire, but later, in order to send it to be unlocked in a local store, flashed the original stock ROM. The phone is unlocked now, but without the IMEI! When I hit the *#06#, it shows only the / ** numbers, the whole 15 digit number is now gone.
I have a backup from my efs folder that I did before sending the phone to the store, I installed GalaxS Unlock and did the backup. But when I access the backup, it doesn't have the .nv_data.bin and .nv_data.bin.md5 that every tutorial asks me to use it in the process. I tried the method of deleting my efs folder and restarting the phone, but that didn't worked either.
Is there something I can do to repair my phone?
Thanks

Do you a have a efs.img backup ? Or any kind of IMEI/EFS/RADIO backup ?
I had the same problem I flashed the stock ROM and somehow I lost my IMEI info, I tried everything and I was even thinking about buying a z3x box but then I decided to do a very risky move , I completely deleted all the EFS related files/info and reflashed again but now I was not able to boot because I always sent me to recovery mode saying that :
"E:Failed To Mount /EFS (invalid argument )"
Then all I did was installing TWRP and rooted my SM-G935F and then I placed my efs.img backup on my internal SD CARD and went on recovery launched the terminal and wrote this :
dd if=/sdcard/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS
Then I wrote reboot and it finally my phone was booting and I recovered my IMEI and was able to use my phone normally.
This only works if you have a backup of your EFS, and even if you do is risky , but I did it because I lost all hope and was accepting the fact that my phone would just become a useless wifi only device .

So there is not a fix yet for this problem ?

I have a problem on my s7edge instead. If i have valid imei i'am almost always in emergency calls, and when the signal comes back does not go into mobile data connection. With the wi fi no problem.Can someone help me i'am going crazy.!
