i have a cyan N9 16 GB , forgot the security code so i had to flash my phone so i zeroize the device with this command
"flasher -f -F main.bin --erase-user-data=secure
flasher -f -F main.bin -F emmc.bin --flash-only=mmc"

this appeared " erasing this may take a while " but when i entered second command it replied with "error code 10 security failue"
" downgrade disallowed "
product code is 059K0Z8

HELP !!
Thanks
