Hacking Could it be possible to downgrade the switch somewhen

[cyrushehe]

It is impossible.

It always seriously disappoints me when people say this.

somewhen not long ago the switch came out

somewhen this new word makes me happy

I actually really like it. It's nice

ARE YOU KIDDING ME? ARE WE GOING TO START A FLAMEWAR OVER EDITING BOOTROM? ITS IN THE FUCKING NAME. ROM MEANS READ ONLY MEMORY.

downgrading will not be a thing with the eFuses in place. although doubtful, a partial downgrade would be the closest thing to a downgrade that would be possible on the Switch assuming the system will boot and not blow the tamper eFuse in that state.

well, from what it has been said in this thread (and i assume you havent read the OP with that answer) it will be possible, but with the exploit we would need to do it, downgrade would be obsolete

It doesn't work that way. The console is hardcoded to read the bootrom from a specific location. You cannot change the bootrom. It is impossible. The 3DS's Read-Only IO registers, which are what turn on when the power button is pressed, are programmed to lead to the Read-Only bootrom. You cannot change the boot process. If you could change it, the 3DS would have been completely hacked in every possible way within a few months of release.

The original xbox says hi. Everything is impossible until someone figures out how to do it.

You can probably open the switch, remove the cpu from the board, decap it, fib the chip (https://en.wikipedia.org/wiki/Focused_ion_beam), repackage it, resolder it to the board. That would be difficult to do today, but not necessarily impossible.

It took ages for the ps3 to be hacked completely. Sometimes it takes a while to figure things out.

If it is a mask rom and not an prom/eprom/eeprom/flash then it still doesn't make it impossible to modify it. It's essentially made out of a grid of connected/unconnected gates. You can modify it if you have the equipment.

Exactly this. We would need to be handed control directly by the bootrom to bypass the efuse verification and use an outdated firmware. And a bootrom hack would make downgrading useless.

Nintendo would likely put the eFuse verification into the bootrom, for maximum protection.

you made fun of somebody who doesn't natively speak english for a title that while not incorrect, sounds odd. this is why i don't like america. and i'm from there. p.s. you might be surprised to find out that the u.s. did not "win" wwii. study abroad when you get to college.

Me too. That's why I dont like America. Guess what? I live in America thanks to my parents, sighing. Made fun of somebody who doesn't natively speak English is a no no. In Europe, they dont made fun of somebody who doesn't natively speak their language.. At least in my country. They are very understanding people. What's wrong with America ? Tsk tsk.

Given the verification value changes with each update I'm pretty sure it needs to be in an area that can be updated. Although I suppose there would be the possibility the efuse checks are done via a specific algorithm in the bootrom. Either way according to the article I linked on Wololo.net the check causes a panic in the early boot chain not the bootrom. In short I'm pretty certain you're wrong.

It seems that each firmware version includes an encrypted hash which is checked by the firmware to determine the number of fuses. Unless you have the correct encryption key you don't have a chance.

it may have been a noob question, as i said in the OP, it is one
but i really wanted an answer, and i got it thanks to people who are glad to help instead of just saying "tsk... another noob"

Oh....well I think I hear my phone's ringtone, gotta go.
