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?

I dunno. I have a 2017 flagship that will no longer even boot to fastboot after accidentally disconnecting the cable during a flash.

Which phone. There’s usually a hidden firmware flashing feature. I had to use that when an update failed on a OnePlus phone. I’ve only ever used ones for snapdragon based phones, never tried anything else.

Essential Ph1. The flashing tool isn't out there anywhere as far as I can find

It has a snapdragon CPU so you'd have to try to find how to get it into EDL mode and potentially a cable for it. With my oneplus phone I rescued the other day I was able to use a regular cable, but that was also with their proprietary software.

Will it boot into fast boot when starting up with like pressing the volume up or volume down key at boot? Because as long as you can get into fast boot, you can fix it.

Yea, it won't boot to fastboot

Oh wow, then you've managed to break it more than I have ever broken a device. Oopse
