efs use ktool app to backup and restore. need cwm?
in twrp, back up your rom and your efs lo. yes in twrp when backup it can backup your efs also.
obviously twrp and cwm cant use each other backup, they are different recovery.
i send one latest copy of my cwm backup to my laptop, and been using twrp backup every since, its faster and smaller to backup.
also do you face efs corrupt often?
i kena once in s2. and never before in s3.
yup..
only 1st time kena this efs corrupted. so kinda like clueless what to do..
yeah. just bcoz last backup i made was in cwm that i think dont have missing imei.
just try n error to find what the working backup.
but after few backups restored.. still cant get my imei back.
then luckily found a backup folder made back in July that stil have working imei.
just gamble copy paste overwrite over the "notworking" efs folder on 4.4. rom.
voila.. its works

all done without bootup my phone into android coz too many time wipe all and restore session.
