Linux에 android bootloader.img 파일을 마운트합니다.

dd를 사용하여 Android 부트로더 mtdblock을 백업했지만 설치하는 데 문제가 있습니다.https://transfer.sh/yAxnI/bootloader.img.

$ sudo losetup -o 8225280 /dev/loop0 bootloader.img  
$ sudo fsck -fv /dev/loop0


fsck from util-linux 2.35
e2fsck 1.45.5 (07-Jan-2020)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/loop0

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>

$ sudo mount -t  vfat -o loop,offset=8225280 bootloader.img /mnt/disk/
mount: /mnt/disk: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error.
