[Q] Xiaomi Mi2s - No cell signal after IMEI restore. - Xiaomi Mi 2

Hi.
I have a Xiaomi Mi2S that doesn't connect to any cell networks.
I'm using CyanogenMod 11 nightlies, and after an update the phone lost its IMEI number. I had taken a backup of the NVRAM using EFS Professional, but when I looked for it the files where 0 bytes in length (probably a hard disk problem on my computer)
After trying a lot of stuff (installing stock MIUI, putting the phone in diag mode and installing a bunch of drivers), I managed to restore the IMEI number, but the phone still can't connect to the network.
I have tried a SIM from another company and it doesn't work. And my SIM works correctly in other phones, so I think that is not a SIM problem.
I don't know what to do... I tried flashing different ROMS, tried flashing a new baseband radio, but I can't get it to work! Is the phone lost???
Can anyone help me? I would appreciate it very much!!!!:crying:

[Q] No Service Need Help

For the life of me I can't figure out what I did wrong. I purchased an Oppo Find 5 from China, rooted and flashed some custom ROMS. Somehow something screwed up my cellular connection. I get no service at all. I've flashed different roms, modems, factory reset ..you name it without success. The SIM card is detected but can't make calls or get data. Any ideas?
Edit: Problem solved: flashed a modem for x909t and now have service. I've been flashing x909 modem and that was the reason for connection failure.

[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

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.!

IMEI, Network Signal and Baseband is misssing
Hi
I am ready to donate if any expert can help me to restore IMEI.
I am using SM-N9500 samsung note 8 model - hongkong version, i frequently change the roms.. when last time i tried to install a custom rom i lost IMEI. i am getting error like IMEI-unknown, baseband- unknown, no network and sim cards not working..
i tried installing stock rom, custom roms, it was installing successfully but only baseband, signal and IMEI are not working. i didnt even back up my EFS folder. So, kindly help me to get back my IMEI.
I have installed stock rom, still no IMEI. now i rooted my mobile and taken EFS backup. is it enough? if yes, pls suggest me the next steps. I also tried installing combination firmware, though is not working, installation was successful and also i am able to see the factory binary logo, after which it will switch off automatically and boot loops. everytime it will open factory binary and immediately it will switch off automatically..

COOL 1 [No Network Signal After Flashing ROM]

I've searched and done so many hotfixes but
Nothing work and I think it's time to ask the experts.
Here's the Problem:
My Phone was in a HardBrick, then Gladly I've made it back
by reflashing the Stock Rom of Cool 1 (EUI 5.8.18s) using QFIL
And then I noticed that there is no network signal even though the sim card is being detected. I've searched on Google on how to fix it and I find out that it must be the IMEI and I re-write the Original IMEI from the Box on my Device successfully but still, nothing happened, I still have no Network Signal. I've done reflashing again through TWRP But still, nothing happened, I tried to switch to (EUI 5.8.17s / 5.9.26s / JUI and MIUI 9) roms. I also tried the *#*#4636#*#* and change the unknown to WCDM / LTE and everything is still the same No Network Signal.
Now I am wondering if it is because I inputted an International IMEI which is written in the Box of this phone, or might be because of my baseband or kernel.
By the way, I'm from the Philippines I'm using (Globe/Smart) Teleco's Sim.
If there's anyone who could show me the right thing to fix my device, your help will be appreciated.
If You are also suffering a HardBrick Case with the same device I am willing to help you to the best of I can do.

Hi there!
I had the same problem, tried rebuilding IMEI's even from my other phones etc. After rebuilding IMEI, appliying qcn with QFIL (after changing to diagnostic mode)... IMEI was available, but network won't work.
But I repeated with .qcn found for C103 on internet .... and it works like a charm! Connects to network!
drive.google.com/file/d/1jp41j9n68qfIVwAKl2Uu6rU6tsfrbJhx/view?usp=sharing
My phone:
