Anybody have any idea how to restore this phone back to stock rom. It cannot be detected by Kies and Odin. When I put this into the download mode, all it shows is :
current binary: Samsung official
system status: official
Knox kernel lock: 0xfffffffc
Knox warranty void: 0xfffffffc
bootloader apswrev: 2
write protection: enable
I bought this phone used and I have no idea what the history is. Can anybody help?
