If you do a clean flash you can start-up your device, enable developer mode and in terminal type: Code: disclaimer-cal remove View-openmode after this you can flash the open mode kernel the following way: Code: flasher -a rootfs.bin -k OPEN_MODE_KERNEL --flash-only=kernel --suppress-warranty-warning -f Now start up your phone and you will be in open mode without the "scary warranty" message...It is safe to do the above and was published by CODeRUS 5 months back His thread describes how you can get rid of the message if you are already using your device in open mode and don't want to do a full flash hence losing your data...However the above is what someone needs to do if he is doing a full flash...
disclaimer-cal remove View-openmode
flasher -a rootfs.bin -k OPEN_MODE_KERNEL --flash-only=kernel --suppress-warranty-warning -f
