E os is on security patch october and stock september. Can i lock the bootloader?
Thanks for help

when you’re back on stock you lock the bootloader again. For the flashing process you keep it unlocked. Backup your data. See the link " Roll back to stock ROM" on the left side at Info about Fairphone FP4 - FP4
