My brother mistakenly wipe his Samsung GT-P5200 without backing it up, and installed a custom rom.
The custom rom is working smoothly, but the phone is not bringing up a network... Always saying "NOT REGISTERED ON NETWORK" whenever I dialed numbers on it.
The custom rom has baseband and imei intact... But I noticed the "EFS PARTITION and RADIO PARTITION are no where to found on the phone... How can I fixed the EFS PARTITION and the RADIO PARTITION?
NOTE:I've tried many official stock roms from SAMMOBILE, SAMSUNG FIRMWARE AND SAMSUNG UPDATES... I've also tried NEEDROM, but I couldn't get the rom for GT-P5200.
