moving back to 1vyrain bios, coreboot is cool and all but I dont think its really worth it
@Mia I’m sat here trying to figure it out but what exactly does 1vyrain do? like why is a jailbreak necessary? is it enterprise lockdown type stuff for the xx30 machines?
@TheIronFox is just lets you flash a custom bios rom without an external flasher
@TheIronFox obv levono doesnt want that but they left some flaws in the old firmwares and its possible to downgrade and abuse those flaws to gain write access to the bios region to flash something like coreboot, or typically a modified bios
mostly to bypass the wwan/wlan card whitelist

@TheIronFox calling it a jailbreak is a stretch but its not my code
@Mia hmmm interesting. now that you point it out, it seems obvs that there would be something akin to bootloader unlocking to flash a bios. just never thought about it before. thanks! :)
@TheIronFox all chromebooks can be internally flashed but most other stuff is externally flashed, certain thinkpads can be messed for internal flashing, but other brands aren't really messed with since nothing like coreboot/libreboot is compatible, and you'd prob want to use an external programmer to develop for a new platform, if they even have a bios chip that can be written to
@Mia fuck google but chromebooks continue to be neat lol
i guess i figured a coreboot flash would be similar to a bios update. is that a separate process? or is there some sort of digital signature or something involved with manufacturer provided files?
sorry for 20 questions lol just trying to wrap my head around it and don’t have access to hardware to try it myself
@TheIronFox I imagine its either a digital signature or it uses a different region, I honestly don't know for sure, this is my first time messing with this, all the other thinkpads I've had needed to be externally flashed, and previously I wanted to go with libreboot which needs the full 12M of the flash chip(s) where 1vyrain only exposes the 4M of the bios region
