[Please help] Cannot unpack System-sign.img for TB3-850M

#1

Hello everyone,
I have system-sign.img from SP Flash Tool Firmware for TB3-850M, I cannot unpack it! Its filesystem is ext4, the size of the system-sign.img is 2.9GB which looks like they merge two system images as I cannot flash it using fastboot as I get this error: "target reported max download size of 134217728 bytes Invalid sparse file format at header magi"

I tried most ways such as Android kitchens and ext4unpacker and ext2explore and 7-Zip and they all fail!

Thanks in advance!

Regards,
addas

Which version of the tool did you use?

retry using this unpacker @ https://hovatek.com/redirect.php?link=ht...-extractor
you should consider searching for a different firmware link.

I tried it makes a check mark and just gives me a blank system folder.

Never mind I flashed the system-sign.img firmware using SP Flash Tool, backed it up using TWRP, and I extracted the firmware from TWRP Backup!

BTW, this issue is the same as this one: ( https://forum.hovatek.com/thread-13567.html ) but the solution isn't written there!
