a Mstar based TCL TV has a sparse_write command, which is not supported.

[hpp0hpp]

Hi,
I got a Mstar based TCL TV has a sparse_write command, which is not supported. I try to modify some lines in utils and unpack.py, I finally got the img file but, when I use simg2img tool to convert to raw file, then lots of content lost.

I totally not sure what happened? I've been search every website for the solution but lack of information and solution, can you help with me about this?
here is the script I got
~header_script.txt

here is the log info

Try my fork of mstar-bin-tools, it should help - https://github.com/sha-man-4pda/mstar-bin-tool

@czqn8 unpacked without any proplem. Probably you have FAT32 filesytem which doesn't allow files bigger then 4GB. Userdata partition is 7.7GB.

@czqn8 this is not an unpack log. Are you trying pack FW under Linux? Then you will need sparse utilities first. I don't know which fork of mstar-bin-tool you're using but it's definitely not mine as I never added Linux support to my fork.
