Hi,

I have unlocked bootloader. On the boot, there is text "Device orange state. Bootloader is unlocked. This device can not be trusted". I want to remove this text for a bunch of reasons.

I know that on most android devices You just need to flash different boot logo, but on some needs to edit hex on hboot.img. How to remove this text from BV9800Pro boot screen?

Ok, so I have found this myself.

To remove bootloader text on MediaTek devices, follow this tutorial: https://forum.hovatek.com/thread-31664.html

OR

If You gave BV9800Pro, You can simply flash modified LK file straight away.
P.S., When You flash using SP Flash Tool (as I did), You have to flash LK and LK2 (You set the same file for both fields, atleast that what I did and it works perfectly).
