Tinfoil on modded switch having installation errors with larger games but works fine with small ones.

Gangstalicious · Jun 7, 2024

I have tried to download Mortal Kombat 1 four times and splatoon 3 once now and each time I get an error; however, when I download small games, like mariomaker 2 or pikmin 4 it works fine. I have gotten a few different errors such as: "corrupted block" and "unknown frame descriptor". I read through previous posts to find solutions and got rid of these by redownloading tinfoil and using DBI to get rid of orphaned files, but now I get a new error that reads "failed to parse github Json!" when Tinfoil tries to download DBI, which is weird considering I already have the NRO on my sd card. If you have any advice please help a brother out I read through the entire rentry guide and couldn't find anything on this

Ps. sometimes I can see my System memory change when I use tinfoil even though I always download to SD and have the space. It only changes by a few hundred megabytes.

Do yourself a favor and send that card to the landfill

As 4d1xlaan said, something's wrong with your SD card. I'd suggest that you check your SD cards with h2testw before putting them.. anywhere, really. Especially if you're not sure if they are legit or not.

You have a fake card that pretends to be larger than it actually is

The switch thinks it's writing to "bigger" areas of the card but the card really just overwrites earlier data instead. So then when it tries to verify the files it just wrote, it fails, because the data it wrote has been partially overwritten (by itself)

It works with smaller games because the smaller games fit on the actual size of the card, so everything gets written correctly without anything being overwritten

Assuming you're using emummc, it sounds like parts of your emummc user partition are being overwritten when trying to install larger games, which would be why you see internal storage change when you're only installing to sd space. It's probably only a matter of time before actually important data gets overwritten from a game install and emummc becomes corrupted entirely. You might have already lost some save data too if you're unlucky.

Thanks for the link! I'm using it right now and it's gonna take an hour and thirty to verify half the sd card. Do you have any sd card brands you recommend and do you know anyways to avoid them getting ruined? This is the card I used: Lexar 256 GB microSDXC memory card.

I usually go with Samsung and SanDisk microSD cards. I only had one Lexar SD card which I got with my 2DS, and it's still working just fine.

Specifically for the Switch, I use SanDisk Extreme 256GB in both of my hacked Switches and they are working just fine, I'm yet to run into an issue.

Not really? Just use them the way you usually do. If they are legit, they should work properly for a long time. I always test them with h3testw to make sure that they are working properly and that's pretty much it, I let them do their own thing.

Yo thanks this made a lot of sense so I got a new official Nintendo brand SD card that I’m sure isn’t fake setup everything on it following the rentry guide to a T, but after downloading ~100 gb of games off tinfoil I got the same problem. The download would stall at low m/s, fail, and my system memory would change. I tried reinstalling tinfoil, rebooting, downloading on fusee, cleaning orphaned files, downloading sys.patches, fixed archive bit, and anything I could find. I’d also get corrupted block errors and many failed to read chunk errors in the console. It’s almost like my sd card is getting corrupted from using tinfoil over time. Everything should work fine my sd card is set to FAT32 and partitioned. So I have no idea. If you know someone who‘s an expert on this or can at least download using tinfoil consistently please send me their contact. I’m worried that my SD card reader is damaged or maybe I just got really unlucky and got 2 defective cards. Also I can’t get the files off my system memory that tinfoil downloads when this happens even after cleaning.
TLDR: got official new card, same shit still happened don’t know how.
