unix3dgforce / lpunpack Goto Github PK

So I've been trying to unpack
OnePlus Nord 2 super images

But when extracting some partitions i get

python3 lpunpack.py -p odm super.img p
Traceback (most recent call last):
File "/storage/emulated/0/Download/update/lpunpack.py", line 450, in
LpUnpack(**vars(namespace)).unpack()
File "/storage/emulated/0/Download/update/lpunpack.py", line 405, in unpack
self.Extract(partition, metadata)
File "/storage/emulated/0/Download/update/lpunpack.py", line 369, in Extract
extent = metadata.extents[partition.first_extent_index]
IndexError: list index out of range

This happens both on PC and phone,

Just to add, if i don't specify any partition all files well be [OK] but they will be broken

@unix3dgforce
LpMetadataPartition, LpMetadataExtent, LpMetadataPartitionGroup and LpMetadataBlockDevice are read from BackupMetadata instead from PrimaryMetadata.

Thanks

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf0 in position 8: invalid continuation byte

It's failing to read the group names because the offsets have been updated.

lpunpack is able to extract a Fairphone 4 super.img file but --info does not show any information:

$ python3 ~/compilethings/lpunpack/lpunpack.py --info super.nonsparse.img 

$ python3 ~/compilethings/lpunpack/lpunpack.py super.nonsparse.img  --format text --info

$ python3 ~/compilethings/lpunpack/lpunpack.py super.nonsparse.img test
