Hi everybody! I have a problem with EFS partition, I'll try explain my problem on the better way possible because I don't speak english.
After several flash via odin and CMW the EFS partition is broke.
When I flash the stock ROM with odin the IMEI is there, but when I flash a Custom ROM the IMEI dissapears and I don't know how fix this!
I tried with EFS pro but print an error:
Device Connection: okay!
Root Access: okay!
Detected 'efs' Partition Location:Failed!
Error:Can't Locate Mount Point!
EFS backup Failed!
Also, before all that, I tried with Galaxy Toolbox, and I did a backup but, this backup not works. I know that because I tried restore the EFS partition on the Custom rom and the IMEI isn't appear.
Somebody can help me please? I want restore the EFS partition.
My SGY is GT-S5360L
If you need more information about my phone, just tell me.
Thanks for read!
Greetings!
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.
Hi there,
a friend gives me his Samsung S4 GT-I9505 with the Problem of no IMEI and no Sim-Card detected.
I tryed a few things like:
- EFS-Backup and restore
- Wipe everything
- New original Samsung Firmware
- New Custom Firmware
- newest Modem installed (the last in the list) (is it for Germany?)
- Now I installed Lineage, Open Gapps and Supersu, but nothing changes.
Is there a way to make a own file for the Imei or something to flash?
I hope you can help me.
sorry for my english... =(
Sorry, but all your attempts to restore the IMEI have been a waste of your time, including restoring the EFS partition. The IMEI and nv_data files are no longer stored in the EFS partition. They have their own hidden partitions that cannot be backed up with TWRP.
The only legal way to restore the IMEI is to take the device to the service center.
