Hello everybody,
I just installed a new rom and I booted my phone and it gave me this message: A problem was detected with your device. Your device IMEI number is invalid. An invalid IMEI number could cause network issues including the inability to call emergency numbers.
Does anybody know how to restore my IMEI?
Thanks in advance
Rick
first thing always provide more detail stuuf like what you did...which rom, version so some ones can help you quickly
are you able to connect to network if yes then don't think you need to worry.
if you're are not able typo connect to network then try flashing different modems and even that not solve your offside them go back to gb and then flash the rom after rooting

I forgot to take backup of efs folder. I found the imei number from the box that the phone came with. I need help to fix the imei issue. Error "No sim detected'. I have Micromax Canvas A250. I have installed colossus Samsung S5 custom rom. I have my IMEI number and I would like to know if there is any option for me to create an EFS folder and add IMEI number to fix this issue. WIFI works just fine. Please help me fix this as I am unable to make any call or use 3G data. I have backedup 'apps+data' option on Titanium backup and copied it in phone and PC. Does it help? Please help me fix it.
Thanks and Regards
Hello everybody!
After restoring with TWRP a backup of MIUI by xiaomi.eu 8.1.3.0 (MAACNDI) stable, the phone shows baseband version unknown and No SIM card message, though the SIM works perfectly fine in other phones. Also, when dialing *#06# it shows correct MEID and both IMEIs, while in settings > about phone > Status > IMEI information it shows the right MEID and IMEIs, but it shows Unknown under IMEI SV (Slot1) and IMEI SV (Slot2).
I've already tried restoring older back-ups, fastboot flashing to global rom, wiping dalvik and cache, multiple reboots. I've run out of ideas. Any ideas about how to get the baseband and the GSM function back?
Also I don't have a back-up phone and I am kind of desperate. Please Help! Thanks!
You didn't back up efs partition with twrp? You should try this thread http://forum.xda-developers.com/mi-5/how-to/xiaomi-mi5-efs-backup-restore-methods-t3432730/page8
I have a TWRP backup of the efs, but after restoring it, there is no change. Actually I think the backup is corupted and it is the culprit that broke my phone, cause when I restored the backup I accidentaly restored the efs too and after that the sim isn't recognized. I tried following the above tutorial, but I'm facing a problem with QPST cause I cannot restore the modified qcn file. It gives me the following error "Received an invalid command from the phone" and the status "Memory Restore Failed!". I don't know what to try next...
For those having the same problem after an efs restore in TWRP this is THE SOLUTION:

THANKS for your answer!
With which version of twrp did you back up efs partition?
The problem was generated by a bug of the TWRP recovery (seems the 3.0.2.0 version, which I used for backup and restore was the one with problems). I think the bug was fixed in later versions, so you should use the latest version to avoid the problem.
My phone is working flawlessly again.
Details about the bug that causes the problem can be found here: http://forum.xda-developers.com/showpost.php?p=68500121&postcount=64

Hi,
Recently I tried to clean flash AOKP on my stock rom using twrp 3.0.2.X, after flashing when i boot up the device it wasnt detecting sim card and the device's IMEI, SN, BT/WIFI/MAC/IP address are unavailable, I manually tried to restore IMEI using this guide but the device cant detect sim card in custom roms like CM/AOKP/MOKEE but when i revert to stock kitkat rom it works fine and I just have NVRAM Error in wifi available wifi list. Please help me resolve this issue. Thanks in advance :fingers-crossed:
Flash stock rom using sp tool
I have tried many custom roms but when i flash it, my imei number becomes unknown and i can't use my wifi and my sim is not detected. I tried and followed every steps but it happened every time. Then when i used the motorola rescue tool and flashed my own firmware i got my imei number back and sim and wifi are also working. I want to use a custom rom, which custom rom should i use?

I tried with leveno app and I can back it up, but still got null baseband not found. I know I asked from you a lot but is there anyway backup EFS and presit (sorry my spelling) into an twrp backup?
Because even I flash the stockrom, it dosent find IMEI numbers and the carrier
