Hacking Question Is it safe to stop a nand backup in progress?

[DualBladedKirito]

Hello I started following this guide:https://gbatemp.net/threads/switch-...homebrew-menu-on-4-x-5-x.504012/#post-7978261
I might have made a dangerous mistake. I forgot to wipe my sd card before making the nand backup and my sd is 32 gb. is it safe to stop the nand backup process or am I screwed?

 

[rajkosto]

yes. however chkdsk your microsd in a computer reader afterwards.

 

[DualBladedKirito]

how do I stop it? I'm kinda scared to push buttons lol @rajkosto

 

[rajkosto]

hold the power button for 12 seconds to force turn-off your switch

Why would you stop it ? Let it finish and if you‘re unsure if your backup is ok then you can format your sd an backup the nand again.

I realized my sd isn't large enough anyway. So I was worried it would overfull the sd and soft brick. Guess I was being a bit paranoid

also how safe is hekate cause right now I don't have an microsd large enough to do a backup right now. should I just try the hbl without the backup or wait till I get a bigger sd?

I think the switch would say somerhing like „error cant backup nand: sd card hasn‘t enough storage“ or it would just stop but there won‘t be any brick.

Buy a bigger sd card before messing around with any payloads! You should never do anything without a nand backup

There's a version that lets you do the NAND backup in parts, so you don't have to get a bigger SD.

There's a payload that'll offload your NAND in 2GB (or even 1GB if you have a tiny SD card) parts that you can recompile back into a full backup.

well my sd is 32 gb but I have switch games(it's my switch's primary microsd) on it gonna try to backup the files on it wipe it and use the empty sd to do the nand backup. would that cause any problems?

Do you know how I would go about stitching the nand payload together after this? My dump was in a bunch of 2GB parts because my sd is formatted fat32. I’d like to just have one big bin file instead.

I'm not sure, I have a 64GB card. What format did the parts come in? There should be about 15, are they in .part1, .part2, etc. format?

It gave me RawNand.bin.00, RawNand.bin.01 all the way up to 14. I want to say I stitch them with dd or something but I don’t want to risk corrupting a nand dump.

I have a 64 gig card too, but the FS is limiting me to 2GB files.

It’s not really a huge issue as much as it is just the convenience of managing one file instead of 15.

You might be able to use 7Zip to join them all together? If you have 7Zip installed, try right clicking on the .00 file and click "Extract to "RawNand.bin\"".

That's a good idea, I'll give it a shot. Thanks.

Ok i got an error around the 75% mark. "Error reading 512 blocks" followed by numbers and letters. It happened 3 times. What does that mean? @rajkosto

do u have another idea to combine the .bin files? 7zip does not work for me, i get an error at 9%...
