Why don't cell phones have BIOS? (lemmy.eco.br)

Why, instead of safely entering a BIOS setup, does the cell phone brick when installing the Custom ROM wrongly? Wouldn't this protection be better for users? I mean, this could be done through ADB.

Also, do you think it's possible that this way of doing things will come to the computer, with ARM hoping to gain a good share of the market and all?

If we are speaking of android phones, they don't have a bios, but they have a bootloader. The bootloader starts the kernel or the recovery, and it can be used to unbrick a device, by reflashing or flashing stock. if you fuck up the bootloader flashing, or disable oem unlocking again and then the phone fucks up, that is the only time the phone can be truly bricked. as for your second statement, the successor to BIOS is UEFI, and UEFI has arm support.
