VIM3

Hello community
@tenk.wang, @jasonl, @goenjoy
so, I want to build a rom, but with a locked bootloader ( that user can’t flash it easily )
any help with that ? the u-boot documentation doesn’t explain that neither the u boot section in khadas docs

@taimed Did you build Android pie rom?

Vim3 does not support secure boot function at present

is it because the build I can make is userdebug ? also ? i can have a try and modify uboot code, I’m can go throught it if I have the right keywords

Hi,
No its not because of userdebug or user build, is because you missing the rest of the binary’s you need to encrypt/secure the bootloader + img + ota zip.
And before you ask where to get them, you wont! :frowning:
