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

Hi.
I have a problem.
Radio band lost in my captivate.
No sim card initialisation.
I put sim card in it... but nothing.
In settings radio shows unknown.
Att captivate.
Can you provide a few more details of your situation?
What rom are you using?
Who is your network provider?
What happened just before you lost your phone connection?
It sounds like you might have a messed up /efs folder, but we would need some additional information to be sure.
Rom was slim ics 4.0.4
I downloaded some programs from play market. And was playing with them.
When it lost i went back to stock gb 2.3
I have tried several sim cards... but all the same
Ok, that sounds like a bad /efs folder.
When you put in a SIM card and go to the settings-about phone-status page, do you see anything under IMEI?
Nothing.
Phone number, network, mobile network type, Imei and imei sv show unknown.
Also baseband version is unknown too
Then you have a messed up /efs folder. There is a post in the development section that tells you how to fix it - here.

Hello, I lost IMEI data from my i9305 :\
Trying to fix it whole day, but I give up now, im done.
I tried several guides (sammobile.com/forum/showthread.php?t=15196) but nothing helps.
Basicly biggest problem I face is that when I dial to *#7284# it shows "Network is not avilable" so nothing happens, or with another method with removing EFS folder, after backuping it at SDcard1 I have no .nv_data file to modify it and fix everything.
I use SentinelROM v6.0, I tried installing some modified modems, but it was retarded from me. I installed one from orginal firmware today meanwhile I was trying to fix IMEI :\
Can anyone help me?
@edit
I dont have backup. Imei and baseband - unknown ;(
I also would like to add that I know my imei (have it written down :3), but can I somehow rebuild efs based on it :3?
I feel so lucky, I flashed orginal firmware through odin and everything is fine now I just need to upload 4.4 again, and make backup for future!
That was my lesson :3 Thread can be closed.
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
Cheers!
Ok Thanks i already installed last twrp and back up efs, i just wanted to be sure about this as i didn't want to go all through this process if i have any trouble

Hey XDA,
I'm hoping that somebody here can help me. I have somehow deleted the IMEI, Baseband and all of that from my phone and I'm unable to get any cellular connection. My wifi and bluetooth still works. I have tried using a generic qcn file to restore the imei but the imei only displayed until I rebooted it, and it didn't restore the network at all. My phone is rooted and setup for diag mode and all of that. I haven't had any success using QPST, I unfortunately do not have a backup and I was wondering if anybody could provide me with a QCN directly from a ZE620KL, WW version preferably. I can edit the IMEI's into the file myself. My phone is rooted using Magisk, currently on Android 8.0
Thanks so much!
