@MK said in Onion bricked? SQUASHFS error...: [ 1.291638] SQUASHFS error: xz decompression failed, data probably corrupt [ 1.298650] SQUASHFS error: squashfs_read_data failed to read block 0xd968a Judging by this error, it's likely there's data corruption on the flash, so the OS can't mount the filesystem during boot. I would suggest trying to re-flash firmware using the bootloader web recovery. If it boots normally after that, it points to data corruption. If not, then that points to an issue with the flash. Let me know how it goes and we can discuss next steps!
