I'm working on a fork of rkflashtool improving it as much as possible:
GitHub - ilmich/rkflashtool: Tools for flashing Rockchip devices
Tools for flashing Rockchip devices. Contribute to ilmich/rkflashtool development by creating an account on GitHub.
github.com
The goal is to create a tool (also graphical and for windows) to facilitate flash operations on internal memory (especially nand). The multitool is the best tool, but for those with nand devices, not the most optimal(yet).
