My Samsung s4 us Cellular IMEI Number and Baseband Unknown
what can i do???
:crying:
What did you do?
Did you try factory reset? I suppose you have no efs backup...
Sent from my GT-I9505 using xda app-developers app
If you've not got an EFS backup available... try restoring back to stock firmware. People have reported that after restoring stock, their IMEI and the sorts have returned.
If you DO have an EFS backup, restore it and all should be ok
I think my phone imei lost.I have imei backup but how can I restore?
hello
i have null imei on my galaxy s4 i9505
how i fix this ?
thanks
Perform a search on EFS, EFS backup and restore on S4, and how to restore if you have the EFS backup already. If not, I guess service center is the proper way to go.
Hello everyone.
Got stock 910C with 5.0.1, today made root and twrp. backed up EFS with terminal emulator (got efs.img) on my sdcard.
Also made EFS backup with twrp.
Flashed custom 5.0.1 rom, right on welcome screen - lots of FCs. Wipes didnt help.
Returned back to backup of stock rom but now EFS got erased. no IMEI and cellular network.
Tried restoring with terminal and twrp - no luck
Can someone advise?
Try to make a software repair with Kies and report back
Dont forget, EFS doesnt contain any IMEI certs or CAL data, so if u clear EFS partition IMEI willl be the same, only SerialNumber will be wiped

can u clarify please. how can be serial number be wiped?
EFS partition -> SerialNo, Bluetooth, WiFi and password + settings
IMEI certs -> SIM LOCK, Imei number. CAL data
As u can see EFS erasing will never destroy imei number

then why did i lose baseband?
When you tried to backup EFS or root you lost MD5 signature of IMEI parititon. Now its gone. In some cases it can be undone by flashing to STOCK firmware.
Please check the screenshot for correct location of EFS partition and M9K partitions
i did restore my EFS by reinstalling stock 5.0.1 with odin.
Looking for EFS folder of G360HU for restoring my phone. Or help me to restore my IMEI.
