Hey! Thank you so much for the tutorial. I tryed it several times but gparted gives me errors everytime I want to resize the fat32 partition. I'm trying different approaches now. But in case it doesnt work. Do you think you are going to upload the 256gb samsung soon? Thanks again.UPDATE-
First off, while working on this project I ended up making a good friend who not only helped me, but helped you. Huge thanks is deserved to Game_Over.
Game_Over and I worked together to bring you an image preloaded with android with switch to flash to your sd card.
Just backup your sd card then flash the image using balenaEtcher, then copy over your backup to the drive that has 3 folders in it (bootloader, swithroot_android and android switchroot files). Thats pretty much it. Android side has Gapps, joycon fix, magisk and Nvidia GameStream pre-installed. (.img write time about 1 hr, validation is also about 1 hour. I skipped Validation but i suggest you dont. Its up to you)
Only downside is..... its only for a Samsung 128gb sd card (.img was made from a Samsung evo 128gb U3 to be exact). You can try to flash it on a different card but I, nor Game_Over are not responsible for any damage to your sd card or your console).
I only have Samsung sd cards, but I would be willing to make different iterations if absolutey needed.
Upcoming .img's are for 256gb Samsung and 512gb Samsung. (not sure what size the andoid partition size woud be yet, but shouldnt be bigger that 28gigs, its not needed imho).
Alright, with that being said heres the link
