Hello, I lost my IMEI number on my Samsung Galaxy S4 GT-I9505 today and I would like to restore my original IMEI back to my phone. I still have my original IMEI of my phone written down. And my Sim Card is not detected.
I do not have any backups!
I didn't make any backups of /efs (sorry!), will do that when I have this problem fixed and backup it on all my computers.
I have searched Google and www.Android.StackExchange.com but couldn't find anything that worked for me. (So please don't mark this as a duplicate question)
- Samsung Galaxy S4 GT-I9505
- I live in The Netherlands
- My carrier is KPN (if you wanted to know that)
- I have my IMEI number written down
- I do not have any backups of
/efs! (sorry!) - IMEI = Unknown
- Baseband = Unknown
- Sim Card not detected
I dialed *#06# to get the IMEI number:
The hidden menu in Android: (*#*#4636#*#* or *#*#INFO#*#*):
Of course, I flashed the stock ROM back on my phone. (Android 4.4.2)
I downloaded a backup of
/efsfrom someone else on the internet and flashed that on my phone. However theIMEIis still "Unknown".When I flash the stock ROM on my phone for my country (The Netherlands), it did restore my IMEI. However WIFI didn't work on the stock ROM, and when I flash Cyanogenmod back on my phone, I don't have an IMEI anymore. (So I think the IMEI wasn't written permanently on my phone).
Any help is appreciated.
If I need to add some more information, just tell me. Thanks!
