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!
