Subject: Feasibility and procedures for repacking firmware for devices running the Rockchip RK3026 processor (often marketed as RK3066 variants).

Customization: replace kernel, enable features, change default apps, remove bloatware.
Localization: add language packs, region-specific settings.
Recovery/repair: reassemble modified partitions after editing or to recover a bricked device.
Security research: audit code or patch vulnerabilities.

If you own a device bricked by a bad OTA update, or if you are a developer trying to customize a ROM, you have likely encountered the nightmare of proprietary firmware. Stock firmware is often distributed as a single update.img file, which is a Rockchip proprietary image format.

Device tree: decompile DTB with dtc if you need to edit hardware configuration.
Root filesystem: if system.img is an Android sparse image, convert with simg2img then mount or extract; for squashfs use unsquashfs; for ext4 loopback mount after losetup.
Make required changes: replace binaries, modify init scripts, add/remove apps, update fstab, adjust permissions, tweak kernel cmdline, or rebuild DTB.

"System.img," Leo muttered, watching the progress bar on his Linux terminal. Using the old reliable Rockchip Kitchen tools, he began the delicate surgery.
