just come back to cwm this morning.
really need it coz twrp cant be use to restore my efs partition.
and twrp also cant read back the backup created by cwm meanwhile cwm can read and restore twrp backup.
one or two the weakness that wont affect much of twrp easy to use interface.

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.
