Can i relock bootloader before or after and remove the Engineering SBL3 in upgrade to Windows 10 Mobile? I have a Nokia Lumia 925 or in case of not, Can only remove the Engineering SBL3, use Windows 10 Mobile and leave the bootloader unlocked?
no need to remove... you can use W10M with bootloader unlocked. you need it for glance FIX and others hacks...
only is important to stay on AU builds, not upgrade to CU because bugs...
