There is no way this can happen.

Well turning power off during saving can corrupt the save file.

Depends on how the firmware gets written desu

Good games create backup saves so revert to that if the latest fails.

it can easily brick something if the update process doesn't duplicate old firmware in a temp file or produce a rollback patch before installing the update

It is impossible. You could always download PS3/PS4 software to a usb drive and do it in safe mode (which you need to for a new hard drive). Pretty sure Xbox One has a diagnostics mode that downloads software if corrupt/none found.

I don't know anything about playstations, but some hardware literally overwrites the boot image when you update, so that would be bad to power off during.

it in fact can happen on dev hardware during stage 4 and stage 5 of the update.
If its stages 1-2 then no it wont brick but it will need to be reinstalled

There's usually a rom area where you can plug a usb in and apply the software. Like a recovery mode. This area cannot be written to but the software downloaded must match the version in the flash memory.

If what you're arguing is that it is impossible to brick the system because you are always technically able to salvage it, then I agree.

>recovery mode doesn't work because it was stored on nor chip

Only launch ps3 had all firmware written to chip.

The system would have to be incredibly poorly designed for that to happen but it is technically possible.

PSP I think did this. You could remove battery during firmware update.

Well, Wii U can be bricked if you power it off. Day one update for this console was so big, that it couldn't be saved in the console's storage. Downloading and updating system firmware in this same time is not a good idea.

the nand/nor chip also carries the ps3 bios. without the bios, the ps3 doesn't know how to operate itself.

You couldn't even update a PSP without charging it close to full even if it was plugged in.

It doesn't keep a backup on there? How many times is this area able to be written to?

But the battery was user removable. You could unplug it and take the battery out during an update.

once the nand/nor chip is corrupted or dead, your ps3 becomes a brick. unless you made a copy of your nand/nor chip with a E3 flasher or Teensy mod.

I better put my consoles on a UPS each time J update then?

some older games do this in a sorta interesting/stupid way. ocarina of time for example has 6 save slots, not 3, so when you save it writes to two slots corresponding to one file. then on boot it checks them to see if they are equal. If they aren't, it just fucking deletes your save.

there's also a "cheat code" on controller 3 to factory erase the SRAM, if you really badly corrupted your shit.

do whatever you want, just make sure your ps3 doesn't cut off while updating.

Didn't brick it, but I did lose all my save files and game data once because of it.

That sucks. I just remember Just Cause 3 freezing on a save. Next time I started it up, it said the save is corrupted but a backup is available. All on the same slot.

Yeah, I guess it depends on how often the backup is created. I think nintendo was probably more concerned with the integrity of batteries and not having the game crash on load. It's still a stupid approach though.
