(Hide) Bootloader Unlocked Warning At Boot

[Dahlia-desu]

Hi, just wondering if this is possible, and if not, whether we could temporarly unlock the bootloader and make changes that would allow screen recording with internal audio support, and then relock?

I have a Huawei P9 on Kirin 955, though I've seen mixed posts/comment asking if it is supported, yet the description in YouTube video link in the Wiki says to "For Kirin 955: Try Kirin 960 or 950 (one of these should work)"

TLDR:

• Can unlocked bootloader message at startup be hidden so device boots as it usually would without the boot loader unlocked message?

• Can we unlock the bootloader and make little changes like allowing internal audio screen recording then relocking for the reason of getting rid of the boot loader message?

• Is Kirin 955 supported by PotatoNV (using 960 or 950?)

• Can all this be done without wiping the device? 🤨
