ok, so serge's 'fix start' patch might have done the trickcan someone provide insight with a problem. i once had havoc is on my 9600 pro (p60 version), but could not hget 4g and volte to work with it, so went back to stock. i now have a second 9600 pro (p70 version), and am trying again.
so i flash stock rom with sp flash tools. boot to unlock the bootloader (have the red letter in right corner for some reason). go to fastboot unlock bootloader, unlock flashing, flash recovery, boot to recovery, flash havoc 3.8 arm 64 AB gapps. flash magisk. wipe, and reboot. every single time it boots back to fastboot (says factory on phone. ) i've tried a couple different roms. same result. after flashing, it boots to fastboot.
