Hey my friend, erofs with amlogic s905x5 on all tools do not work due to the format of the erofs type.

error on all files such as these.

sha256sum: ./system/app/Firefox/Firefox.apk: Input/output error
sha256sum: ./system/app/Firefox/oat/arm64/Firefox.odex: Input/output error

sha256sum: ./system/app/MouseAssist/MouseAssist.apk: Input/output error

and these for all files too

tar: ./lib64/libvibratorutils.so: Read error at byte 0, while reading 8704 bytes: Input/output error

File shows this is the type of EROFS.

system.img: EROFS filesystem, compat: SB_CHKSUM MTIME, blocksize=12, exslots=0, uuid=0BD9DE47-790E-7851-B14A-D3CA17AF1F02, incompat: LZ4_0PADDING BIG_PCLUSTER

Let me know if there is anything I can do, here is a generic image if you want to check you are welcome too, thank you very much.

Thanks for your time.

Also super.img would not show as a single_partition_file to decompile, so I decompiled super and tried each partition, cheers

Ok lemme check

[ravindu644]

Also super.img would not show as a single_partition_file to decompile, so I decompiled super and tried each partition, cheers

Sorry, what did you mean?

Can you provide any logs?

[JasonBrooks1984]

I was able to decompile the super partition once I went into the advanced portion, that was my error, but the other errors are once any of the other partitions were decompiled, thank you very much.

Looks like this image isn't even a file system that is mountable

[JasonBrooks1984]

That is all the new formats of Amlogic and firmware upcoming, I software engineer and write from SDK but want to help a friend with this project, I can mount it, but the files can not be copied out of the fusemount folder, any ideas on this, your project is promising and extracted more than any other tool.

I will pull the changes and check to see if there is any changes. Cheers!

[JasonBrooks1984]

I saw the changes and figured I would try, same thing, I have tried so many manual methods with no dice. Hope you can figure it out, it has been but not many sharing how. I can mount and see, but can not copy the contents under any circumstance. YELP!!!! LOL.

[ravindu644]

I will pull the changes and check to see if there is any changes. Cheers!

I guess they won't do anything :)

can you give me a real .img pulled from a firmware to analyze?

[JasonBrooks1984]

That is a real image, just needs to be decompiled as an amlogic firmware, here is a super.img uploaded to check out. Here is the super.img for ya, you are doing awesome, great work! Cheers

Okay, lemme investigate

[JasonBrooks1984]

Thank you very much, if there's anything I can do please let me know, I appreciate it.

Hey, I took a look at your images.

It looks like they are Erofs images, but they aren't mountable using the normal kernel mount procedures. After looking at the dmesg, it seems like your Amlogic uses a faulty or a customized Deflate compression method in the erofs images, which the kernel cannot understand.

However, I was able to mount it using erofsfuse and was actually able to enter the file system.

They were readable.

But the issue is I have to find a proper method to copy all the files from the mounted location to another location.

My current implementation of copying files is failing for an unexplained reason.

I have to test more. Even if I were able to copy the files, I have no idea if they would copy correctly without corruption.

Also, it seems like I have to write the entire logic of the unpack script to fix this issue, which might fix your issue but introduce more random bugs in the script.

Just seeing if you made any progress, keep up the great work
