Hacking Is there such thing as a permeant brick?

pablo67340 · Jan 1, 2021

Hey there,

Just out of curiosity, I wanted to ask if there was such thing as a permanent brick? By this I mean, even using an RCM Jig, You can no longer boot into Hekate? For example, say I was re-writing my nand, and half way through my console died. Would this potentially result in a brick that prevents Hekate from launching? Perhaps this wouldn't be the method to do it, but could something like this happen? From what I've gathered from my switch, I honestly couldn't think of a way that someone could make it so their switch no longer boots into Hekate.

Well, thanks for the read. Hopefully some of you smart bois have the answer for me

P.S Happy New years everybody!

Not that I have a modded switch, but shouldn't you be at like 75% percent before you try to do ANYTHING with the nand? Im to chicken right now to mod my switch, but I feel like that's just a general rule. I feel like as long as you don't touch anything with RCM You should be fine, but again, I'm no expert. To permanently brick anything you REALLY have to screw up somehow

If you have a sysMMC and BOOT0/1 backup, then there generally isn't a software brick you can't recover from.

What @Lacius said. Backing up Nand and Boot 0/1 will help greatly prevent permanent brick. Generally, people just create emuMMC, which is a copy of sysMMC but separate from it. Hope it helps, anyone feel free to elaborate on this.

As a general rule of thumb, if you backup sysnand, boot0/1 and then create emunand to mess around you should be fine. Precaution is always better than cure.

Pertaining to switch modding because there exist several different models so if you have ver1 switch which have the read only rcm exploit you will never suffer a unrecoverable softbrick since you could load any recovery software to do nand recovery. However the same cannot be said for ipatched and mariko units since the rcm exploit has been patched and requires hardware mode to access rcm and it is currently closed sourced. It is made much more complicated with additional security fuse check etc.

Personally I will always do a nand/rom backup of any device I planned to mod before messing around with it etc and it has saved me a lot of trouble doing a recovery or if you simply want to resell it.

Only literally a hardware failure

Even then, should you have a backup you can write it to a new eMMC module.

sadly there are still permanent ways to get bricked even software wise. It's just a lot harder than any normal person should do.

any suggestions? my issue is my switch lite is currently not powering on at all. tried a force restart. hard reset and tried to boot into safe mode. neither has responded. i even unplugged the battery too and that didnt work. the only indication i see so far is a green light.

Is this still in warranty? Hard to tell, many things can cause a Swich Lite not to turn on. Potential faulty component chip within the motherboard. When you say green light, what exactly do you mean?

Well I found the issue it seems to be with the lcd screen. I happened to move a button and sounds came out. So the issue is more likely a bad lcd screen. Have to get that fixed

Can you report when you try to fix it if it worked? I would greatly appreciate it.

Short of a hardware brick, or a really fucked up software brick, I'd say it's impossible, even if your prodinfo was now corrupted there are ways to recover it even without a backup. @linuxares should have mentioned that smh (jk plz don't ban me)

You mean getting the screen fixed?

There is such a thing but it cannot be achieved with the current software. Someone can make it but that requires a bit of effort.

Sorry for not responding sooner well the repair went okay but sadly it didn't help. When I plugged everything back in nothing worked and I smelled a faint burning smell. So I pulled the plug and let it sit for a day or two. Still don't work, if you need to get it fixed get done by a pro because I'm sol now. I had to end up buying a another low serial switch so I can run cfw on it. Good luck
