I have problems restoring my /efs folder
I tried backup apps and like 1000 file managers with root, but i cant delete/overwrite anything in /efs folder
Even tried Dead repair + RE-partitioning but still no luck... and Clear EFS in ODIN
Any way to mount folder /efs only, because other system folder have no problems...
Please Help
Thanks
There are many posts with ploblema IMEI or signal loss!!!!
Ok for friends who have completely corrupted EFS folder then the phone is "without imei" just write this file via ODIN in PDA
mega.co.nz/#!lxdgHCpL!UXThp1fT2HKrTJA_G1czASiKjkkrit-FjVJSwiexPFQ
This file restores EFS with a standard imei 004999010640000 then proceed to restore your imei staff with the method you prefer.
I used Z3X.
So basically i thought i had a backup of my EFS through Philz Recovery before i started to root and flash Darkstalker Rom V5. Well i ticked the option to fix the EFS partition in the aroma setup box and after installation, i see that i have a corrupted IMEI and Serial Number. I transfer the backup to restore it and to my surprise, it contained system, data, and cache but no efs. What are my options here? Any help would be appreciated..
Have you tried Odin to stock?
Odin to stock!
I have i8262 model. Root Explorer shows no files and folders under efs folder but dialing *#06# shows my imei. I cannot even mount my efs folder in recovery. (says failed to mount error) My phone shows an overlay of "Update Device Information"
I think my efs partition got corrupted but somehow imei is shown.
So, How can I backup my imei and restore efs partition?
Shall I just format it?
is there any way to rewrite imei without efs backup?
IMEI is NOT saved in /efs
