Hi all,
I just upgraded from CM12 to CM13 (with full wipe) and somehow the IMEI and baseband information got corrupted.
So I restored a efs backup (using dd). Now IMEI (3597...), serial and baseband is back and the phone recognizes the sim card.
But if I enter the PIN code it doesn't unlock the sim card (checked the sim card successfully in an other phone).
Any ideas?
GT-9100
Android 6.0.1
CM 13.0-20160818-Nightly-i9100
Baseband I9100XXLS8
Just after posting this, I had an other idea:
In the restored efs partition I replaced the nv_data.bin and .nv_data.bin.md5 with the *bak*-files.
And after a reboot everything is working now
(seems that my backup was also corrupted... )

Hi everyone,
I just flashed my phone for the first time from 4.3 Stock to Cyanogenmod 11 (Snapshot M10) following these steps :
Using ClockWorkMod I backed up all my device.
In recovery mod I did a factory reset
I installed from sdcard the CM11 file
I installed from sdcard the GApps file
Reboot
After 1-2min, before I can do anything (reconfigurate my "new" phone"), I have to log on my phone via SIM's PIN.
Even with the right PIN, I have a "login on the network" screen and can't do anything.
At this point, I though it would be a network (modem ?) issue
I disconnected the SIM and rebooted the phone and here is what I figured out :
IMEI is OK (the same on both Stock and CM11)
Serial Number is broken (different from Stock)
I've searched on the forums but I couldn't find some people with the same problem : generally IMEI and Serial Number are both broken
I have no clue how to restore the serial number only.
Would a EFS restore do the trick ?
For information, I don't know if that's relevant : my device is a Samsung Galaxy SIII i-9300, and I live in France, using Orange as provider.
Thank you for your help
PS : I just restored my phone via the backup I did. All works fine (but I'm back on 4.3 :/ )
There are problems with the recent CM11. Try another CustomRom: AOKP-, Omni-or TW-based.
First flash full stock room with Odin, if serial not recovered then restore your efs backup.
Once it's all working again then start custom flash again.
Device:Micromax a27 bolt

Problem: Device not recognizing after flashing stock rom.
I was recently having some problems with my device.So i thought to flash stock rom.
But flashing the ROM with flasher was unsuccessful but i found a update.zip which could be flashed using fastboot.
Then flashed the rom with fastboot but then i inserted SIM CARD and it was not recognised by the device.
I thought the IMEI would be missing but i used imei write tool.
When clicked READ IMEI then i was showing my device actual IMEI but there's no IMEI number.
I checked *#06# its still not showing the IMEI and SIM card in not recognizable.
Need some suggestions fast.
Hi, I´ve just got a Oukitel U7. This is a MTK 6582.
And at first look seems "nice". My issues start when I insert a sim card. Then it loses the Imei and dont connect to sim card. When I remove de sim card, I have Imei again.
So, any one experienced something like this ?
I already rooted, make a Imei backup, restore it. Flashed with SPFT and nothing seems to work.
Some ideias would be nice...
thank you

try to flash with new update with spft on needrom.com
Hello.
So basically my problem is when i insert any sim card my baseband version is going unknown same as imei. It happens on every rom except S5 sensation rom. Whenever i try to restore efs or modem device still has unknown imei and baseband. But when I pull the sim card out it is known and correct. Any way to repair that?
Thanks in advance
Hey everyone, I need your help badly..
Device: Rmx2151
Android: 10
RUI:1.0
Bootloader: Unlocked
IMEI : NULL
Baseband: repaired
Problem level: software level(100% sure)
The Problem:
I can't use my sim card without wifi connect.
My nvram partion was corrupted, and so my IMEI and baseband was lost,(no backup)
I managed to recover baseband version by (as someone told me that it is mandatory to use sim card) deleting "nvram" folder from twrp file manager.
But my sim card still won't work, it only works when I connect to wifi, and as soon as i disconnect wifi the mobile networks also disappears,
Others who used the same method on this very device to recover baseband have a fully functional sim.
I also tried all other stock rom firmware files RUI1/2/3 A10/11/12
Heres how it looks:-
