    1) When you updated to 8.0, did you use autoRCM to preserve your efuses?

    2) When you downgraded back to 4.0, did you do so with a Nand backup or with choiNX?

    You will need to use rcm booting through Hekate so it ignores the fuse burn count. Stock bootloader will check the fuse count and if you burnt them (which it sounds like you did) it will panic and not boot
