Tpsk706spc822 Firmware Repack -

| Tool | Purpose | |------|---------| | binwalk | Analyze and extract the firmware structure. Detect squashfs, uImage, or cramfs. | | dd / blkid | Carve out specific partitions. | | unsquashfs / mksquashfs | For squashfs-based root filesystems. | | firmware-mod-kit (FMK) | Automates extraction, repacking for many router/embedded types. | | hexdump / xxd | Manual header and checksum inspection. | | openssl / cmac | Decrypt or recalculate cryptographic signatures. | | python3 + crcmod | Custom checksum recalculation scripts. |

mksquashfs squashfs-root/ new_rootfs.squashfs -comp xz -b 256k -noappend For JFFS2 or YAFFS, use mkfs.jffs2 . This is the most error-prone step. You must replace the old filesystem chunk in the original tpsk706spc822.bin with your new_rootfs.squashfs while keeping the header, footer, and bootloader intact. tpsk706spc822 firmware repack
