Oh, sorry my bad if you misunderstood or if I'm just being weird, but basically, I have a 128gb official Nintendo MicroSD that I tried to use for booting L4T but whenever I did so via Hekate I got greeted with a backlit screen that did nothing regardless of how long I wait. After a week or so of troubleshooting I resorted to my 3DS' MicroSD (16gb) to see if my SD was the issue and even though my 128gb was real, it's like incompatible with L4T and I was just confused as to why L4T worked with a 16gb MicroSD and not a 128gb, as if there is some compatibility difference

It could potentially be what flasher program you use maybe but it's weird about what it does. Im using balenaEtcher to flash the files

Ah ok, thanks for clarifying, I think bylaws is coming up with an update soon for the sd card fix... have you done the same method with the 16gb card?

I've used balenaEtcher and rufus for the 128gb, yet it just doesn't want to work, so flashing onto that specific SD is the issue

Yes I did the exact same method as the 128gb and it worked just fine on my 16gb, but ah good to know that they're coming for a fix. Got an approx time when that'll be? I might just buy a 64gb MicroSD and use my 128gb for Atmosphere stuff, where the 64 will be for linux

Actually holdup, regarding my 128gb MicroSD issue, I have a friend who just got it working on a 128gb... so is my write speed too fast?

Hmm @VibrantSubbed do you know the r/w speed

Check your read and write speed

--------------------- MERGED ---------------------------

It could be possible that the switch legit can't read/write if it's too fast

Try speed out or h2testw on windows
For Linux you can use gnome disks and go under your SD card sd# and open up benchmark and do a write benchmark or default benchmark
Reading speed is 23.9mb according to h2testw
(I used it before to verify I don't have a fake SD)

@bylaws since I used the 1.2 update, it wont let me install anything in ubuntu, it just tells me I don't have permission to install anything

Reading package lists... Done
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission Denied)
E: Unable to lock directory /var/lib/apt/lists/
W: Problem unlinking the file /var/lib/apt/pkgcache.bin - RemoveCaches (13: Permission Denied)
W: Problem unlinking the file /var/lib/apt/srcpkgcache.bin - RemoveCaches (13: Permission Denied)

Never mind, sudo

SpeedOut says Reading speed is 72.727 mb/s whereas Writing speed is "error"

EDIT: I figure it's an error with SpeedOut, but is it because I use a U3 MicroSD?

@bylaws Basically my issue is that when it comes to booting L4T on the switch, it seems to work when I use a U1 16gb MicroSD but when I use my 128gb U3 Official Nintendo MicroSD, it seems to fail and I can not determine whether it's an sd write speed issue or anything. I did the exact same steps in the 16gb sd card after I constantly fail with the 128gb and it worked first try. I'm just wondering if you have some sort of fix for this.

I feel like it's the issue of it being U3

I think you can also test read and write speed with Hekate too

@bylaws Hello, this is working flawlessly so far, but it seems the kernel is missing the midi sequencer (snd_seq_hw_open returns no file or directory)
Could you include it in the next update?
Thanks.
Sure

It might be fixed next update

Is there a special check if the original dock is used or some setting to get the screen on tv? I tried my 3rd party adapter (Melopow M002) which works without any issues on OFW but on ubuntu I cannot get hdmi output. Can other adapters and docks be supported somehow? Maybe I should check if there's a linix driver available for my adapter?
