I have a Verizon Galaxy S3 SCH-i535. I OTA updated from 4.1.2 to 4.3
I know that the bootloader cannot be unlocked, but can I flash custom ROMs that are 4.3 based? Perhaps that won't modify my bootloader?
Short answer: yes. Long answer: read me and thank Badusername. You're only able to flash roms that explicitly state VRUCML1 or ML1 in the title.
